    Full Text Available Sarcoidosis is a granulomatous disorder of unknown cause, affecting multiple organs, but mainly the lungs. The exact order of immunological events remains obscure. Reviewing current literature, combined with careful clinical observations, we propose a model for granuloma formation in pulmonary sarcoidosis. A tight collaboration between macrophages, dendritic cells and lymphocyte subsets, initiates the first steps towards granuloma formation, orchestrated by cytokines and chemokines. In a substantial part of pulmonary sarcoidosis patients, granuloma formation becomes an on-going process, leading to debilitating disease and sometimes death. The immunological response, determining granuloma sustainment is not well understood. An impaired immunosuppressive function of regulatory T cells has been suggested to contribute to the exaggerated response. Interestingly, therapeutical agents commonly used in sarcoidosis, such as glucocorticosteroids and anti-TNF agents, interfere with granuloma integrity and restore the immune homeostasis in autoimmune disorders. Increasing insight into their mechanisms of action may contribute to the search for new therapeutical targets in pulmonary sarcoidosis.

    We report a case of optic disc granuloma due to sarcoidosis. A 64-year-old, caucasian female with a history of pulmonary sarcoidosis presented with a vision loss on her left eye. The ophthalmologic examination revealed a discrete optic disc infiltrate compatible with the diagnosis of optic disc granuloma. Fluorescein angiography showed diffusion and impregnation of the granuloma without vascularitis. The optical coherence tomography demonstrated a homogenous and isoreflective lesion at the optic disc. The patient recovered her visual acuity after systemic corticosteroid treatment. Isolated optic disc granuloma is a rare condition of ocular sarcoidosis. Copyright © 2016 Elsevier Masson SAS.

    The formation of noncaseating granuloma is a hallmark of pulmonary sarcoidosis. This review summarizes recent progress made to explain the cellular dynamics within the granuloma structure that may considerably differ between the two clinically distinct variants, that is, acute and chronic sarcoidosis. Compelling evidence exists that in acute but not chronic sarcoidosis CD4 T lymphocytes specifically recognizing the auto-antigen vimentin on human leukocyte antigen-DR3 molecules accumulate in sarcoid granuloma. These so-called TH17.1 cells produce high amounts of the TH17-related cytokines interleukin-17 (IL-17) and IL-22 in addition to interferon-γ. Moreover, regulatory T cells from patients with acute sarcoidosis are ICOS, providing a mechanistic link to the comparably high concentration of IL-10 exclusively found in the airways of these patients. Next to obvious differences in T effector cell and Treg subsets, alveolar macrophages harbor a functional mitochondrial system in acute sarcoidosis patients, while this system is impaired in patients with chronic disease. We provide a comprehensive update on the cellular components and their functional implications in sarcoid granuloma formation, with special emphasis on the specific characteristics of granuloma in acute versus chronic sarcoidosis. Moreover, the specific antigens thought to be involved in both forms of the disease are discussed.

    To establish a C57BL/6 mouse sarcoidosis granuloma model elicited by mycobacterial superoxide dismutase A peptide (SodA). Thirty female C57BL/6 mice were randomly divided equally into 5 groups: a combination (SodA+Sepharose) group, a SodA group, a IFA (incomplete Freund's adjuvant) group, a sepharose group and a blank control group. On the first day, the combination group and the SodA group were sensitized by subcutaneous injection of 50 µg SodA incorporated into IFA 0.25 ml. The IFA group and the Sepharose group were treated with subcutaneous injection of IFA 0.25 ml and PBS 0.25 ml respectively, while the blank control group was not given any treatment. On the 14th day, the combination group was challenged by tail vein injection of 50 µg SodA covalently coupled to 6000 agarose 4B beads (in PBS 0.5 ml) . The SodA group was challenged by tail-vein injection of 50 µg SodA (in PBS 0.5 ml) . The IFA group and the Sepharose group were treated by tail-vein injection of 6000 agarose 4B beads (in PBS 0.5 ml) , while the blank control group was not given any treatment. On the 22th day, the mice were dissected and the gross and pathological changes of lymph nodes and lungs were observed. Immunohistochemisty was used to identify Mac-2 and CD(+)4T in granuloma. Counts and differentials of BALF cells were measured. CD(+)4/CD(+)8 in BALF and cytokines (IFN-γ and IL-12 ) levels in the lungs were detected by flow cytometry. Enlargement of peripheral and pulmonary hilar lymph nodes were found in the combination group and the SodA group, and sarcoidosis granuloma was found in the lymph nodes and lungs of the combination group. Sarcoidosis granuloma was also found in the lymph nodes but not in the lungs of the SodA group. No sarcoidosis granuloma was observed in the lungs and lymph nodes of the IFA group, the Sepharose group and the blank control group. Macrophage specific antigen Mac-2 and CD(+)4T were positive in the core and rim of the granuloma respectively. The lymphocyte

    To investigate if there are dust particles in the cells of granulomas of sarcoidosis and analyze its composition and the possible correlation between the sarcoidosis and the composition of dust particles. The samples of 50 patients with sarcoidosis and 6 patients with silicosis as control were collected by biopsy and/or autopsy sampling. The pathological varieties of the granulomas and the situation of the dust particles within the cells of granulomas were observed using hematoxylin and eosin staining, Warthin-Starry silver staining, immunohistochemistry staining as well as the transmission electron microscope, and the X-Ray spectrum chemical element analysis in the samples from these two kinds of diseases. The dust particles containing silicon as the main chemical element were present in epithelioid cells and multinucleate giant cells in all the samples. The quantity of the particles deposited in sarcoidosis was less than that in the silicosis. Moreover, the dust cells were found in the granulomas and the visceral pleural lymphatic vessels in the pleura and the hilar pulmonary lymph nodes in sarcoidosis and silicosis. The pathological varieties of the granulomas in sarcoidosis and silicosis were similar. There are less silicon dust particles in the cells of granulomas of sarcoidosis than in those of the silicotic nodules, which indicates that the silicon dust particles may be related to the sarcoidosis.

    2016-09-01

    Up to twenty percent of patients with sarcoidosis develop pulmonary fibrosis, transforming an often benign disease into a highly morbid and potentially fatal one. We highlight the fibrotic pulmonary sarcoidosis phenotype as an area of intense clinical and translational investigation, review recent developments in treatment, and provide a roadmap for future research in sarcoidosis associated pulmonary fibrosis. Granulomatous inflammation in a lymphatic distribution is the hallmark finding of pulmonary sarcoidosis and the nidus for fibrosis. Recent research demonstrates that fibrotic sarcoidosis begins in the setting of persistent, uncontrolled inflammation, and is aided by pro-fibrotic genetic features and immune responses. Comparison to other fibrotic lung diseases also reveals key features that inform our understanding of common pathways in fibrosis. Understanding the mechanisms of fibrotic transformation in sarcoidosis enhances clinical care and facilitates development of novel therapeutic options. The impact of these findings in fibrotic sarcoidosis may be amplified through application to other interstitial lung diseases marked by inflammatory to fibrotic transformation. Important aspects of clinical management of fibrotic sarcoidosis include surveillance for co-morbidities, such as pulmonary hypertension, airway disease, and infection, and assessment for pulmonary disease activity that may benefit from immunosuppression.

    Sarcoidosis is a systemic disease of unknown cause that is characterised by the formation of immune granulomas in various organs, mainly the lungs and the lymphatic system. Studies show that sarcoidosis might be the result of an exaggerated granulomatous reaction after exposure to unidentified antigens in individuals who are genetically susceptible. Several new insights have been made, particularly with regards to the diagnosis and care of some important manifestations of sarcoidosis. The indications for endobronchial ultrasound in diagnosis and for PET in the assessment of inflammatory activity are now better specified. Recognition of unexplained persistent disabling symptoms, fatigue, small-fibre neurological impairment, cognitive failure, and changes to health state and quality of life, has improved. Mortality in patients with sarcoidosis is higher than that of the general population, mainly due to pulmonary fibrosis. Predicted advances for the future are finding the cause of sarcoidosis, and the elucidation of relevant biomarkers, reliable endpoints, and new efficient treatments, particularly in patients with refractory sarcoidosis, lung fibrosis, and those with persistent disabling symptoms.

    Full Text Available Abstract Sarcoidosis is a multisystemic disorder of unknown cause characterized by the formation of immune granulomas in involved organs. It is an ubiquitous disease with incidence (varying according to age, sex, race and geographic origin estimated at around 16.5/100,000 in men and 19/100,000 in women. The lung and the lymphatic system are predominantly affected but virtually every organ may be involved. Other severe manifestations result from cardiac, neurological, ocular, kidney or laryngeal localizations. In most cases, sarcoidosis is revealed by persistent dry cough, eye or skin manifestations, peripheral lymph nodes, fatigue, weight loss, fever or night sweats, and erythema nodosum. Abnormal metabolism of vitamin D3 within granulomatous lesions and hypercalcemia are possible. Chest radiography is abnormal in about 90% of cases and shows lymphadenopathy and/or pulmonary infiltrates (without or with fibrosis, defining sarcoidosis stages from I to IV. The etiology remains unknown but the prevailing hypothesis is that various unidentified, likely poorly degradable antigens of either infectious or environmental origin could trigger an exaggerated immune reaction in genetically susceptible hosts. Diagnosis relies on compatible clinical and radiographic manifestations, evidence of non-caseating granulomas obtained by biopsy through tracheobronchial endoscopy or at other sites, and exclusion of all other granulomatous diseases. The evolution and severity of sarcoidosis are highly variable. Mortality is estimated at between 0.5–5%. In most benign cases (spontaneous resolution within 24–36 months, no treatment is required but a regular follow-up until recovery is necessary. In more serious cases, a medical treatment has to be prescribed either initially or at some point during follow-up according to clinical manifestations and their evolution. Systemic corticosteroids are the mainstay of treatment of sarcoidosis. The minimal duration of

    Sarcoidosis, which occurs most commonly in African American women, is a granulomatous multisystem disorder affecting the skin, lungs, and central nervous system. In a previous immunohistochemistry study of keloids, a scar granuloma stained highly positive for glioma-associated oncogene homologue (gli)-1. This observation led us to study whether gli-1, one of the vertebrate zinc finger transcription factor genes of the gli superfamily, is expressed in granulomatous skin disorders such as cutaneous sarcoidosis, granuloma annulare (GA), and necrobiosis lipoidica diabeticorum (NLD). Immunohistochemistry studies for gli-1 were performed on biopsy specimens from patients with cutaneous sarcoidosis, GA, and NLD. All sarcoid lesions were highly positive for gli-1 expression, and 75% of the cells demonstrated positivity with a stain intensity of 3 on a scale of 1 to 3. The gli-1 expression was confined to cutaneous granulomas. CD68 staining was highly positive in the sarcoid lesions as well. Similarly, GA and NLD lesions were uniformly positive for gli-1 expression. We found that gli-1 is inappropriately expressed in granulomatous lesions of the skin such as cutaneous sarcoidosis, GA, and NLD. These findings provide a rationale for clinical trials of inhibitors of gli-1 signaling, including tacrolimus and sizolimus, for the treatment of cutaneous sarcoidosis and other granulomatous disorders of the skin.

    Sarcoidosis is a systemic granulomatous disease of unknown cause affecting young and middle-aged adults. Patients commonly present with bilateral hilar lymphadenopathy, pulmonary infiltrates, and ocular and skin lesions. The heart, liver,spleen, salivary glands, muscles,bones, kidneys, and central nervous system also may be involved. Diagnosis is based on clinicoradiologic findings plus histologic evidence of noncaseating epithelioid granulomas, and exclusion of other granulomatous diseases. Prognosis correlates with mode of onset, host characteristics, initial clinical course, and extent of disease. The optimal management of sarcoidosis has not been well defined. Although corticosteroids remain the mainstay of treatment, there is little evidence for the optimal initiation, dosage, or duration of therapy. Topical steroids maybe considered for treatment of anterior uveitis and skin lesions. Systemic steroids are indicated for treatment of cardiac, nervous system, severe ocular, and symptomatic or progressive pulmonary involvement. There is little evidence for the efficacy of inhaled steroids. Cytotoxic agents and immunomodulators usually are reserved for treatment of complex or refractory disease. Of these agents, methotrexate is used more frequently because of its safety profile and possible steroid-sparing effects. Antimalarial agents are used frequently for skin lesions, and they have limited success in the treatment of pulmonary disease. Lung and cardiac transplantation is reserved for end-stage disease. Monitoring for symptoms of drug toxicity is essential, and prevention of osteoporosis must be addressed in patients taking long-term oral corticosteroids. It is not known if current therapy alters disease progression.

  14. Lack of cathepsin activities alter or prevent the development of lung granulomas in a mouse model of sarcoidosis

    Full Text Available Abstract Background Remodeling of lung tissues during the process of granuloma formation requires significant restructuring of the extra-cellular matrix and cathepsins K, L and S are among the strongest extra-cellular matrix degrading enzymes. Cathepsin K is highly expressed in various pathological granulomatous infiltrates and all three enzymes in their active form are detected in bronchoalveolar lavage fluids from patients with sarcoidosis. Granulomatous inflammation is driven by T-cell response and cathepsins S and L are actively involved in the regulation of antigen presentation and T-cell selection. Here, we show that the disruption of the activities of cathepsins K, L, or S affects the development of lung granulomas in a mouse model of sarcoidosis. Methods Apolipoprotein E-deficient mice lacking cathepsin K or L were fed Paigen diet for 16 weeks and lungs were analyzed and compared with their cathepsin-expressing littermates. The role of cathepsin S in the development of granulomas was evaluated using mice treated for 8 weeks with a potent and selective cathepsin S inhibitor. Results When compared to wild-type litters, more cathepsin K-deficient mice had lung granulomas, but individually affected mice developed smaller granulomas that were present in lower numbers. The absence of cathepsin K increased the number of multinucleated giant cells and the collagen content in granulomas. Cathepsin L deficiency resulted in decreased size and number of lung granulomas. Apoe-/- mice treated with a selective cathepsin S inhibitor did not develop lung granulomas and only individual epithelioid cells were observed. Conclusions Cathepsin K deficiency affected mostly the occurrence and composition of lung granulomas, whereas cathepsin L deficiency significantly reduced their number and cathepsin S inhibition prevented the formation of granulomas.

    The aggregation of hypertrophic macrophages constitutes the basis of all granulomatous diseases, such as tuberculosis or sarcoidosis, and is decisive for disease pathogenesis. However, macrophage-intrinsic pathways driving granuloma initiation and maintenance remain elusive. We found that activation of the metabolic checkpoint kinase mTORC1 in macrophages by deletion of the gene encoding tuberous sclerosis 2 (Tsc2) was sufficient to induce hypertrophy and proliferation, resulting in excessive granuloma formation in vivo. TSC2-deficient macrophages formed mTORC1-dependent granulomatous structures in vitro and showed constitutive proliferation that was mediated by the neo-expression of cyclin-dependent kinase 4 (CDK4). Moreover, mTORC1 promoted metabolic reprogramming via CDK4 toward increased glycolysis while simultaneously inhibiting NF-κB signaling and apoptosis. Inhibition of mTORC1 induced apoptosis and completely resolved granulomas in myeloid TSC2-deficient mice. In human sarcoidosis patients, mTORC1 activation, macrophage proliferation and glycolysis were identified as hallmarks that correlated with clinical disease progression. Collectively, TSC2 maintains macrophage quiescence and prevents mTORC1-dependent granulomatous disease with clinical implications for sarcoidosis.

    Sarcoidosis is a major cause of granulomatous uveitis but rarely manifests as multiple choroidal granulomas. This report describes the use of enhanced depth imaging optical coherence tomography (EDI-OCT) to visualize changes occurring in multiple choroidal granulomas during treatment. The patient was a 36-year-old Japanese man with histopathologically confirmed sarcoidosis, who was examined using EDI-OCT and showed multiple yellowish-white subretinal lesions in the peripapillary region and the arcade of the right eye. EDI-OCT revealed homogeneous hyporeflective choroidal lesions with choriocapillaris thinning, consistent with a diagnosis of choroidal granulomas. Subretinal fluid adjacent to one of the peripapillary choroidal lesions was also apparent. EDI-OCT during oral prednisolone administration revealed a decrease in lesion size at as early as 3 weeks and complete resolution of the lesions after 6 months of treatment. However, 2 months after prednisolone discontinuation, EDI-OCT revealed recurrence of choroidal granulomas in the peripapillary region and the arcade of the right eye. After injection of triamcinolone acetonide into the posterior sub-Tenon's capsule (sub-Tenon's injection), EDI-OCT demonstrated a reduction in granuloma lesion size within 3 months of the injection. EDI-OCT allowed detailed morphologic visualization of the choroidal granulomas caused by sarcoidosis. This imaging technique was useful for monitoring changes in granuloma size in response to steroid administration and for early detection of recurrence. Injection of triamcinolone acetonide into the posterior sub-Tenon's capsule was as effective as oral prednisolone for the treatment of choroidal granulomas.

    Sarcoidosis is a systemic disease that may present as tattoo granulomas. A patient with systemic sarcoidosis who developed a granulomatous reaction within a tattoo is presented to stimulate interest in this unusual phenomenon. A patient with a 6-year history of pulmonary sarcoidosis developed sarcoidal granulomas restricted to one pigment of a tattoo. Previous reports of sarcoidal granulomas within tattoos are reviewed, and information about the pathogenesis of this process is explored. Sarcoid granulomas may develop in tattoos as an isolated local reaction or as the presenting sign of systemic sarcoidosis. The reaction itself may provide insight into further understanding the pathogenesis of sarcoidosis.

    Sarcoidosis is one of the leading causes of inflammatory eye disease. Ocular sarcoidosis can involve any part of the eye and its adnexal tissues, and may cause uveitis, episcleritis/scleritis, eyelid abnormalities, conjunctival granuloma, optic neuropathy, lacrimal gland enlargement and orbital inflammation. Glaucoma and cataract can be complications from inflammation itself or adverse effects from therapy. Ophthalmic manifestations can be isolated, or associated with other organ involvement. Patients with ocular sarcoidosis can present with a wide range of clinical presentations and severity. Multi-disciplinary approaches are required to achieve the best treatment outcomes for both ocular and systemic manifestations. PMID:26593141

    Granulomatous inflammation is considered an immune mechanism against infection or certain non-neoplastic conditions. Sarcoidosis-like granuloma reactions (SGRs) in primary tumors or in regional lymph nodes are occasionally observed; however, they are rare in lung cancer. In this study, we reported on a case of squamous lung cancer with swollen mediastinal lymph nodes, similar to sarcoidosis. He was misdiagnosed as benign lymph node SGRs or tuberculosis for 2 years. Reexamination of the lymph node by immunohistochemistry confirmed the malignant disease. The lung cancer appeared to remain in the stasis phase for 2 years and then burst to stage IV with the amplification of the fibroblast growth factor receptor 1 gene. Although tumor-induced draining lymph node granulomatous reactions are rare, they did exist in some of the patients. In this case, differential diagnoses with malignant granulomas should be performed carefully to avoid the misdiagnosis of a benign disease. The biological significance of such a granulomatous response in inducing tumor remission or in shielding tumor cells from host lymphocytes remains obscure. © 2015 John Wiley & Sons Ltd.

    Full Text Available Gallbladder granulomas are exceedingly rare, reported in association with tuberculosis or sarcoidosis. Here we report a case of gallbladder granulomatous cholecystitis occurring in the context of sarcoidosis. A 70-years old man presented with abdominal pain, nausea and vomiting. The medical history revealed sarcoidosis diagnosed more than 20-years previously. 2-years previously the patient showed renal lithiasis, hypercalcemia and, increased angiotensin converting enzyme. The imaging features suggested thoraco-abdominal sarcoidosis. Prednisone was given at 1.2 mg/kg/day initially, than decreased, being at 2.5 mg/day at present. The ultrasound examination showed gallbladder lithiasis. A cholecystectomy was performed. Microscopy showed subacute and chronic cholecystitis with several epithelioid and giant cell granulomas some of them perineural. In conclusion, we report a case of granulomatous cholecystitis occurring in the course of treated sarcoidosis. The perineural location of granulomas may give further insights into the pathogenesis of gallbladder dysmotility.

    Sarcoidosis is a multisystem inflammatory disease defined histologically by the formation of noncaseating granulomas. The etiology of sarcoidosis remains unknown. Heart involvement in the course of sarcoidosis concerns about 5% of patients. The most common manifestation of cardiac sarcoidosis are conduction abnormalities, arrhythmias and heart failure. The diagnostic algorithm includes performing a clinical history, a 12-lead electrocardiogram (ECG) and an echocardiogram. If any of the initial screening investigations yields an abnormality, diagnostics should be continue using advanced imaging techniques: cardiovascular magnetic resonance (CMR) or fluorodeoxyglucose positron emission tomography (FDG-PET). Nowadays endomyocardial biopsy is not performed routinely.The clinical picture of cardiac sarcoidosis is highly variable. Screening for cardiac sarcoidosis should be performed in all patients diagnosed with extracardiac sarcoidosis. Cardiac sarcoidosis should also be suspected in young patients without a diagnosis of sarcoidosis who present with conduction abnormalities of unknown etiology, because cardiac sarcoidosis may be the first or the only manifestation of the disease. © 2016 MEDPRESS.

    Sarcoidosis is a systemic, clinically heterogeneous disease characterized by the development of granulomas. Any organ system can be involved, and patients may present with any number of rheumatologic symptoms. There are no U.S. Food and Drug Administration–approved therapies for the treatment of sarcoidosis. Diagnosing sarcoidosis becomes challenging, particularly when its complications cause patients’ symptoms to mimic other conditions, including polymyositis, Sjögren syndrome, or vasculitis. This review presents an overview of the etiology of and biomarkers associated with sarcoidosis. We then provide a detailed description of the rheumatologic manifestations of sarcoidosis and present a treatment algorithm based on current clinical evidence for patients with sarcoid arthritis. The discussion will focus on characteristic findings in patients with sarcoid arthritis, osseous involvement in sarcoidosis, and sarcoid myopathy. Arthritic conditions that sometimes coexist with sarcoidosis are described as well. We present two cases of sarcoidosis with rheumatologic manifestations. Our intent is to encourage a multidisciplinary, translational approach to meet the challenges and difficulties in understanding and treating sarcoidosis. PMID:20665396

    Musculoskeletal manifestations in the context of sarcoidosis are frequently observed. The rheumatologist regularly encounters this disease in clinical practice. In the present review, we aim to give a current overview of the manifestations and treatments relevant to the practicing rheumatologist. The most frequently encountered manifestation is Lofgren's syndrome, which is characterized by bilateral ankle periarthritis, bilateral hilar lymphadenopathy, and erythema nodosum and has an excellent prognosis. Chronic arthropathy most commonly manifests as oligoarthritis, which sometimes hampers its differentiation from spondylarthropathies, especially when sacroiliitis, enthesitis or dactylitis are simultaneously present. Isolated vertebral granulomas are rare and require infectious and malignant disorders to be excluded, since there are no specific imaging findings that are exclusively found in vertebral sarcoidosis. The presence of granulomas in skeletal muscle is common in muscle biopsies, whereas clinically overt myopathy is present in only around 1-2% of patients. Therapeutic responses vary among the different clinical phenotypes. Non-steroidal anti-inflammatory drugs and low to medium dose glucocorticoids are the first-line therapy for musculoskeletal manifestations and often lead to adequate disease control in acute sarcoidosis. When these are ineffective or not tolerated, steroid-sparing agents are increasingly used in chronic sarcoidosis. Evidence for all medications used in sarcoid-related arthritis is comparatively scant. When supplementing vitamin D, the possible development of hypercalcemia, even at standard doses, needs to be considered; the optimal therapeutic levels for the prevention of medication-induced osteoporosis in sarcoidosis have not been firmly established.

    To report two patients with sarcoidosis initially presenting with cicatrizing conjunctivitis. Both patients with chronic conjunctivitis were referred for further management. The first patient had conjunctival granulomas, subepithelial fibrosis, and forniceal foreshortening. The second patient had extensive upper and lower conjunctival scarring with forniceal foreshortening and symblepharon formation of both eyes. Conjunctival biopsy specimens revealed noncaseating granulomas. Immunofluorescein studies were negative for immunoreactant deposition in the basement membrane. Because of further diagnostic evaluations, sarcoidosis was determined to be the final cause of the cicatrizing conjunctivitis. Sarcoidosis should be included in the differential diagnosis of cicatrizing conjunctivitis. Recognition of the characteristic noncaseating granulomas in the conjunctival biopsy and initiation of the appropriate evaluations are essential in establishing the diagnosis and determining the extent of systemic involvement.

    Stone, Richard W.; McDaniel, Willie R.; Armstrong, Earl M.; Young, Roscoe C.; Higginbotham-Ford, Edith A.

    1985-01-01

    Sarcoidosis is a recently identified cause of functional asplenia that can be diagnosed by radionuclide imaging. A 31-year-old woman with a five-year history of histologically compatible sarcoidosis was found to have nonvisualization of the spleen on technetium 99m sulfur colloid (radiopharmaceutical) liver-spleen scan. This scintigraphic finding was accompanied by poikilocytosis and Howell-Jolly bodies in the peripheral blood smear. A subsequent gallium 67 citrate scan reflected an abnormal increase in concentration of activity in the spleen, suggesting an active inflammatory process. Based upon this constellation of findings, it was concluded that acquired functional asplenia is the result of reticuloendothelial cell replacement via infiltration of the spleen by epithelioid cell granulomas of active sarcoidosis. This case also illustrates the reversibility of functional asplenia of sarcoidosis following adrenocorticosteroid therapy. Functional asplenia in sarcoidosis is now found to have a recognizable radionuclide imaging pattern. ImagesFigure 1Figure 2Figure 3 PMID:3908697

    Full Text Available During the last two decades many advances have been made in the field of sarcoidosis. The disease is now recognised as a multisystem disorder occurring in patients with a genetic predisposition and an exposure to yet unknown transmissible environmental agent/s. The diagnosis is based on a compatible clinical and/or radiological picture, histological evidence of non-caseating granuloma and exclusion of other diseases capable of producing a similar clinical or histological picture. Treatment primarily consists of administration of corticosteroids, although there are valuable alternative drugs. Treatment should be considered in symptomatic patients with evidence of radiologic or lung function deterioration. The patients with extra-pulmonary involvement particularly with ocular, myocardial, and neuro-sarcoidosis almost always need treatment. For asymptomatic pulmonary sarcoidosis patients no therapy is needed.

    Although the initiating factor(s) is unknown, it is now accepted that pulmonary sarcoidosis develops as a result of an over-stimulated local cellular immune response. Starting as a lymphocytic alveolitis, there is a progression to granuloma formation within the interstitium as stimulated T lymphocytes release mediators capable of attracting and activating monocytes to differentiate into macrophages and epithelioid cells. We are also aware that macrophage-like cells must act as antigen present...

    Directory of Open Access Journals (Sweden)

    Bindu Suparna M, Joshi Shivani

    2014-07-01

    Full Text Available Sarcoidosis is a Greek word (Sarco means flesh and Eido means type or like. Cutaneous sarcoidosis occurs in up to one third of patients with systemic sarcoidosis. This disease is characterised by the presence of non – caseating epitheloid cell granulomas in the skin. Cutaneous sarcoidosis presents as a diagnostic challenge to the dermatopathologists due to its varied presentations and almost identical histologic pictures. Hence, exclusion of infectious causes and compatibility with clinical and radiologic picture serve as significant criteria to come up to a diagnosis. Sometimes; skin lesions are the first manifestation of systemic sarcoidosis. This is not a contagious or allergic disease. There is a risk of development of systemic manifestations at a later date; for which a close follow up is a must. We are presenting a case of cutaneous sarcoidosis, which later on progress to sarcoidosis with systemic manifestations.

    A 41-year-old man presented for evaluation of a widespread eruption. The eruption started six months beforehand as bumps within pre-existing black tattoos over his trunk and arms. One month later, the patient developed eye pain and the diagnosis of a uveitis was made. A different eruption soon followed, which the patient described as patches of rough skin. Finally, the patient developed discrete patches of hair thinning. The clinical examination, history, skin biopsy findings, and elevated angiotensin-1 converting enzyme and immunoglobulin levels supported the diagnosis of systemic sarcoidosis, which manifested as a sarcoidal tattoo granuloma, perifollicular cutaneous sarcoidosis, and uveitis.

    Madureira, Pedro; Pimenta, Sofia; Cardoso, Hélder; Guimarães Cunha, Rui; Costa, Lúcia

    A 35-year-old man presented with a 3-year history of arthralgia and purple coloration of the skin of his fingers and feet. Hand and foot radiography showed cystic bone lesions on phalanges suggestive of sarcoidosis. Lab tests revealed increased liver enzymes. Liver MRI evidenced an enlarged liver and retroperitoneal lymphadenopathy. Histological analysis of the finger skin, lymph nodes and liver demonstrated the presence of granulomas, confirming the diagnosis of sarcoidosis. The patient started prednisolone with rapid improvement of the symptoms. Skin lesions are divided into two groups: specific for sarcoidosis (with granulomas, lupus pernio-like) and nonspecific (without granulomas, erythema nodosum-like). Specific cutaneous lesions usually cause no other symptoms beyond cosmetic changes. Lupus pernio stands out for having distinctive features but, to the best of our knowledge, the simultaneous involvement of both hands and feet has never been reported.

    Sarcoidosis involving the nervous system probably occurs in about 4% of patients. The usefulness of brain scintigraphy in these cases has been suggested. In this case of cerebral sarcoid granuloma, gallium imaging demonstrated the lesion before treatment and showed disappearance of the lesion after corticosteroid treatment, which correlated with the patient's clinical improvement.

  20. Fatigue syndrome in sarcoidosis.

    Górski, Witold; Piotrowski, Wojciech J

    2016-01-01

    Sarcoidosis is an inflammatory disease of unknown etiology. Most commonly it results in the formation of non-caseating granulomas in intrathoracic lymph nodes and lung parenchyma, but the clinical course and picture may be complicated by extrapulmonary involvement and many non-respiratory signs and symptoms which are directly related to the disease. In addition, sarcoidosis patients may suffer from a plethora of symptoms of uncertain or unknown origin. Fatigue is one of these symptoms, and according to some authors it is reported by the majority of patients with active sarcoidosis, but also by a smaller proportion of patients with inactive sarcoidosis, or even with complete clinical and radiological remission. Therefore the term fatigue syndrome is frequently used to name this clinical problem. The definition of fatigue syndrome in sarcoidosis is imprecise and the syndrome is usually recognized by use of validated questionnaires. In this review the uptodate knowledge in this field was presented and different challenges connected with this syndrome were described.

    Sarcoidosis is a systemic granulomatous disorder of unknown cause. Apparition or flare of previously diagnosed sarcoidosis following hematopoietic stem cell transplantation (HSCT) has rarely been reported. We report a 62-year-old woman who presented a radiological flare of sarcoidosis post-autologous stem cell transplantation for a POEMS syndrome. Imaging findings and lymph node histology, which revealed non-caseating granuloma, were consistent with the sarcoidosis diagnosis. The patient was asymptomatic and was kept free of treatment. Sarcoidosis must be considered ahead of compatible clinicoradiological presentation occurring after HSCT. Sarcoidosis can mimic metastatic cancer or lymphatic relapse. Tissue biopsies and exclusion of differential diagnosis of granuloma diseases are warranted to confirm sarcoidosis diagnosis. Copyright © 2017 Société Nationale Française de Médecine Interne (SNFMI).

    Full Text Available Sarcoidosis is classified as an acquired systemic granulomatous disease. Because of the fact that sarcoidosis affects multiple tissues and organs, it is characterized by many potential signs and symptoms, as well as by the presence of non-caseating granulomas in the organs involved. Although oral sarcoidosis is relatively rare, it may however, present in the oral cavity. This report presents a rare case of sarcoidosis with the initial presenting symptom as severe generalized gingival enlargement. The gingival enlargement was treated by gingivectomy. After histopathological examination of gingival biopsy and certain special investigations, a diagnosis of sarcoidosis was made.

    Disorders of calcium metabolism, especially hypercalcemia and hypercalceuria, are common in sarcoidosis. They are caused by extra renal unsuppressed production of 1,25 dihydroxy vitamin D at the level of the sarcoid granuloma. Hormonal changes during pregnancy have a physiological synergistic effect on this mechanism, which is primarily parathyroid hormone (PTH) dependant. However, the combination of primary hypoparathyroidism with hypocalcemia and sarcoidosis is rare. Di George syndrome, is a dysmorphic disorder characterised by aplasia\\/hypoplasia of thymus and parathyroid glands in addition to aortic arch anamolies and facial dysmorphia.

    The cutaneous signs of sarcoidosis are extremely polymorphous and may be classified under several different headings. Herein, we report the case of a 51-year-old female patient presenting bilateral livedo of the knees accompanied by systemic signs with polyarthralgia, impaired general state of health, weight loss, and a sensation of dyspnoea. Skin biopsy revealed giant-cell granuloma around the dermal vessels, with no caseous necrosis. Histopathological examination of the patient's blood vessels revealed no abnormalities. Laboratory tests showed high levels of angiotensin converting enzyme (1.5×ULN), bilateral mediastinal adenomegaly and incipient pulmonary fibrosis. Systemic sarcoidosis was diagnosed on the basis of the overall clinical and laboratory picture. The patient subsequently presented hepatic involvement and hypercalcaemia associated with the sarcoidosis; systemic corticosteroid therapy (prednisone) was initiated, with slow dose-reduction. The outcome was favourable with a return to normal laboratory values, regression of the adenomegaly and subsidence of the livedo. The literature contains reports of a number of cases of livedo heralding sarcoidosis. The majority of such cases involved young or middle-aged female patients of Asian origin presenting systemic sarcoidosis, with a high frequency of ocular and neural involvement. Livedo could be accounted for by the specific disposition of granulomas around the arterioles, resulting in disturbance of local blood flow, which was probably associated with the mechanical compression of vessels and with the micro-thrombi noted at histology. Livedo may be considered a clinical sign of cutaneous sarcoidosis. Laboratory tests to screen for sarcoidosis may be proposed in the exploration of atypical livedo.

    2015-01-01

    Sarcoidosis is a systemic inflammatory disease characterized by the development of noncaseating granulomas in multiple organ systems. Many hematologic malignancies and solid tumors, including melanoma, have been associated with sarcoidosis. We describe the clinical and pathologic findings of a 54-year-old man with melanoma-associated sarcoidosis. In addition, we not only review the literature describing characteristics of other melanoma patients with sarcoidosis, but also the features of melanoma patients with antineoplastic therapy-associated sarcoidosis. Sarcoidosis has been described in 80 melanoma patients; sufficient information for analysis was provided in 39 of these individuals. In 43.6% of individuals (17 out of 39), sarcoidosis was directly associated with melanoma; in 56.4% of oncologic patients (22 out of 39), sarcoidosis was induced by antineoplastic therapy that had been administered for the treatment of their metastatic melanoma. The discovery of melanoma preceded the development of sarcoidosis in 12 of the 17 (70.5%) individuals who did not receive systemic treatment. Pulmonary and/or cutaneous manifestations of sarcoidosis were common among both groups of patients. Most patients did not require treatment for sarcoidosis. Melanoma patients—either following antineoplastic therapy or without systemic treatment—may be at an increased risk to develop sarcoidosis. In antineoplastic therapy naive melanoma patients, a common etiologic factor—such as exposure to ultraviolet light—may play a role in their developing melanoma and sarcoidosis. PMID:26083934

    Sarcoidosis is a systemic disorder of unknown cause that is characterized by the presence of noncaseating granulomas. The radiological findings associated with sarcoidosis have been well described. The findings include symmetric, bilateral hilar and paratracheal lymphadenopathy, with or without concomitant parenchymal abnormalities (multiple small nodules in a peribronchovascular distribution along with irregular thickening of the interstitium). However, in 25% to 30% of cases, the radiological findings are atypical and unfamiliar to most radiologists, which cause difficulty for making a correct diagnosis. Many atypical forms of intrathoracic sarcoidosis have been described sporadically. We have collected cases with unusual radiological findings associated with pulmonary sarcoidosis (unilateral or asymmetric lymphadenopathy, necrosis or cavitation, large opacity, ground glass opacity, an airway abnormality and pleural involvement) and describe the typical forms of the disorder as well. The understanding of a wide range of the radiological manifestations of sarcoidosis will be very helpful for making a proper diagnosis.

    Sarcoidosis is an inflammatory disease characterized by non-caseating granulomas in the absence of other autoimmune processes, infectious diseases, or foreign agents. The etiology of sarcoidosis is not completely understood. Several organ systems can be affected, of which the most frequently involved include the lungs and lymph nodes. Intra-abdominal sarcoidosis is less common, but can be found in the absence of pulmonary or lymphatic disease. Intra-abdominal sarcoidosis is most often asymptomatic. However, long-standing unrecognized disease can result in life-threatening complications. The identification, monitoring and prevention of these complications will be discussed, with emphasis on both clinical and histological presentations of intra-abdominal sarcoidosis.

    In recent years we have observed with increasing frequency granulomatous papular lesions involving the knees, for which we proposed the term papular sarcoidosis of knees. To evaluate the clinicopathological features of papular sarcoidosis of the knees. Patients with papular lesions of the knees and histopathologically sarcoid granulomas were included in the study. Systemic sarcoidosis was investigated in all cases. Clinical charts were retrospectively retrieved. Biopsy specimens were evaluated under polarized light to detect foreign bodies. Fifty-three patients fulfilled inclusion criteria. In 36 cases systemic sarcoidosis was diagnosed and these cases were considered as papular sarcoidosis of the knees. Foreign particles were observed in 21 of these 36 patients. In only 9/36 patients did the activity of systemic disease persist over two years. In 17 cases sarcoidosis could not be demonstrated during follow-up. Papular sarcoidosis of the knees can be considered a relatively frequent form of cutaneous sarcoidosis usually present at the beginning of the disease that can be useful for the diagnosis of sarcoidosis. It is mainly observed in acute forms of sarcoidosis and can be considered a sign of good prognosis.

    Sarcoidosis is a multisystemic disorder of unknown cause that is characterized pathologically by noncaseating granulomas and predominantly affects the lungs and the lymphatic system, especially intrathoracically. Diagnosis is based on the association of a compatible clinical and radiological presentation, the presence of characteristic histopathological lesions and the exclusion of other potential causes of granuloma. Although the lungs and mediastinal lymph nodes are almost involved, endobronchial nodular lesions of sarcoidosis with lung involvements are rare. We report a case of sarcoidosis with lung involvements and endobronchial nodules as confirmed by bronchial biopsy. © 2014 John Wiley & Sons Ltd.

    A 66-year-old woman, who was diagnosed with iritis, visited our hospital due to general malaise. A blood analysis revealed hypercalcemia. Computed tomography revealed mediastinal and hilar lymph node hyperplasia. Moreover, 67Gallium scintigraphy demonstrated strong accumulation in the lesions, suggesting sarcoidosis. A core needle biopsy (CNB) of the hypoechoic areas of the thyroid was performed because the patient refused to undergo a bronchoscopic examination. The scattering of slightly acidophilic epithelioid cell granulomas was observed in the pathological examination of the biopsy specimen. Based on this finding, the patient was diagnosed with sarcoidosis. Although sarcoidosis rarely involves the thyroid gland, in the present case, thyroid CNB was an alternative diagnostic method that allowed a pathological diagnosis to be obtained. PMID:28781308

    Sarcoidosis is an unexplained systemic granulomatosis. Bone localizations of the disease are rare. We report a maxillary localization. A 35-year-old patient consulted for facial dysmorphia first observed 2 years before. This swelling was associated to nodular panniculitis lesions and xerostomia. The facial asymmetry was due to maxillary gingival and alveolar swelling. It was associated with scarring in the legs and a purple nodular facial lesion. Lip and jaw biopsies revealed epithelioid and giant cell granulomas without caseous necrosis. The panoramic dental X-ray showed diffuse horizontal alveolar ridge lysis and CT scan revealed an osteolytic lesion of the right maxilla associated to a bone-condensing lesion of the left hemi-mandible. The diagnosis of sarcoidosis is made in case of epithelioid and giant cell granulomas without caseous necrosis and the ruling out of other possible diagnoses, including tuberculosis. Bone involvement is rare; face and maxillary localization are extremely rare. The recommended treatment is corticosteroids. Facial remodeling surgery is not recommended.

    We explored the relationship between erythema nodosum (EN) and sex, age, serum angiotensin converting enzyme (ACE), bronchoalveolar lavage lymphocytosis (BAL-I), interstitial granulomas and radiological stage in patients presenting with pulmonary sarcoidosis in Ireland. Sixty-nine patients diagnosed with sarcoidosis between 2003 and 2006 were studied. Forty one patients (59%) were male. Sixteen patients (23%) presented with EN. Forty one patients of 65 (63%) had transbronchial biopsies demonstrating non-caseating granulomas. Patients with sarcoidosis presenting with EN were more likely to be female (p=0.042), younger (p=0.012) and have earlier stage pulmonary disease (p=0.02). There were no correlations between serum ACE, interstitial granulomas and disease stage. BAL-I did however predict increasing disease radiological stage (p=0.042). In this study, one quarter of patients with sarcoidosis presented with EN among their presenting features. These patients were more likely to be young females with early stage radiological disease.

    Sarcoidosis is an idiopathic multisystem granulomatous disease that commonly involves the skin in 25% of affected patients. Because lesions assume a vast array of morphologies, a classification dividing them into specific (with presence of typical granulomas in the biopsy) or nonspecific (not containing granulomas) has been proposed. In the first group the variant morpheaform is considered exceptional. We review the cases reported in the literature and describe the possible differential diagnosis. We highlight the importance of recognizing the very atypical presentation of sarcoidosis and its ability to mimic morpheaform or sclerosis diseases in our patients.

    Full Text Available Sarcoidosis is a systemic, multi-organ disease of unknown etiology characteristically defined by the development of non-caseating granulomas. The development of sarcoidosis has been associated with a number of environmental and microbacterial factors coupled with genetic susceptibility. Depending on the type, location and distribution of disease, sarcoidosis can cause functional impairment, symptomatic distress, scarring and disfigurement. The advent of lasers as precise, minimally destructive surgical tools has allowed for their development as promising alternatives that minimize the morbidity associated with current therapies.In this paper, we reviewed the role of laser therapy in the treatment of cutaneous sarcoidosis. A comprehensive search of the Cochrane Library, MEDLINE and PUBMED databases was performed to identify relevant literatures investigating the role of laser therapy in the treatment of cutaneous sarcoidosis. In our opinion, laser therapy, particularly PDL, appears to be an effective, safe and generally well-tolerated modality for the treatment of cutaneous sarcoidosis and should be considered in patients with localized cutaneous disease that is refractory to conventional treatments. Less is known about the efficacy and tolerability of ablative laser therapy for the treatment of cutaneous sarcoidosis, though the limited data appears promising as well. With that said, however, the data is limited and warrants a need for additional larger, randomized controlled studies to further investigate the utility and efficacy of laser therapy in the treatment of cutaneous sarcoidosis.

    Full Text Available Background: leishmaniasis infection might manifest as sarcoidosis; on the other hand, some evidences propose an association between sarcoidosis and leishmaniasis. Most of the times, it is impossible to discriminate idiopathic sarcoidosis from leishmaniasis by conventional histopathologic exam. Aim: We performed a cross-sectional study to examine the association of sarcoidosis with leishmaniasis in histopathologically diagnosed sarcoidal granuloma biopsy samples by polymerase chain reaction (PCR. Materials and Methods: We examined paraffin-embedded skin biopsy samples obtained from patients with clinical and histopathological diagnosis as naked sarcoidal granuloma, referred to Skin Research Center of Shaheed Beheshti Medical University from January 2001 to March 2010, in order to isolate Leishmania parasite. The samples were reassessed by an independent dermatopathologist. DNA extracted from all specimens was analyzed by the commercially available PCR kits (DNPTM Kit, CinnaGen, Tehran, Iran to detect endemic Leishmania species, namely leishmania major (L. major. Results: L. major was positive in PCR of Eight out of twenty-five examined samples. Conclusion: Cutaneous leishmaniasis may be misinterpreted as sarcoidosis; in endemic areas, when conventional methods fail to detect Leishmania parasite, PCR should be utilized in any granulomatous skin disease compatible with sarcoidosis, regardless of the clinical presentation or histopathological interpretation.

    Sarcoidosis is a multisystem disorder of unknown origin, characterized by the accumulation of lymphocytes and mononuclear histiocytes inducing the formation of noncaseating "naked" epithelioid granulomas. The lungs, lymphatic system, and skin are most often affected, but sarcoidosis may affect any organ. Cutaneous involvement of sarcoidosis is often the sentinel sign of the disease, with the skin sometimes being exclusively affected. We present a case of a 54-year-old African American woman with long-standing history of pulmonary sarcoidosis that presented with multiple verrucous cutaneous lesions on the upper and lower extremities mimicking carcinoma. The initial cutaneous biopsy was superficial in nature, and the pathologist raised the consideration of a possible keratoacanthoma. A deeper skin shave biopsy was performed, and the histopathology showed verrucous pseudoepitheliomatous epidermal hyperplasia with scattered noncaseating granulomas in the superficial dermis. Stains (acid-fast bacillus, Periodic acid-Schiff, and Gomori-Grocott methenamine silver stains) were negative for microorganisms. Given the clinical setting and histomorphology of the cutaneous lesions, the diagnosis of verrucous sarcoidosis was rendered. Verrucous sarcoidosis is a rare cutaneous manifestation of sarcoidosis that could be easily misdiagnosed if it is not appropriately biopsied. This hinders the precise evaluation of the histological specimen, overall clinical picture, and administration of appropriate therapy.

    was investigated in granulomas from sarcoidosis patients with the use of immunohistochemistry. RESULTS: The HLA-G*010102/-G*0106 alleles were observed more often in sarcoidosis patients (39.4%) than in controls (26.4%), p = 0.025 (Fisher's exact test); however, not significant after correction (p(c) = 0.15). When...... HLA-G expression was investigated by immunohistochemistry in granulomas from sarcoidosis patients, weak HLA-G expression was observed in only one patient. CONCLUSIONS: HLA-G alleles that include a 14-bp sequence polymorphism in exon 8 of the HLA-G gene are observed more often in sarcoidosis patients...... than in controls. The sequence variation may influence HLA-G mRNA stability and influence the expression of soluble isoforms of HLA-G. Only rare and weak expression of HLA-G was observed in granulomas from sarcoidosis patients. More studies are needed to further elucidate the possible role for HLA...

    Sarcoidosis is a systemic non caseous granulomas disease. Liver is a common location but usually asymptomatic. Evidence based guidelines for this location treatment is lacking and the effect of corticosteroids may be inadequate. The aim of our study was to describe the clinical, biochemical, radiological and therapeutic features of seven patients with systemic sarcoidosis and liver involvement. A retrospective and descriptive monocentric study, over 3 years, including seven patients with systemic sarcoidosis and liver involvement. We included 5 women and 2 men with an average age of 43 years. Hepatic localization revealed sarcoidosis in 5 cases. Hepatomegaly was observed in all patients as well as abnormal serum liver function test reflected by anicteric cholestasis. Liver biopsy, showed in all granulomatous lesions consistent with sarcoidosis and severe fibrosis in 2 cases. Extra-hepatic manifestations were present in all patients represented mainly by pulmonary location. All patients were treated, five by corticosteroid and two with ursodeoxycholic acid (UDCA). Complete response was observed in one case, partial response in another case and corticosteroid refractoriness in one case. In two cases, corticosteroid therapy was introduced for less than 1 month, not allowing assessment of response. Antimalarials in combination with UDCA were used successfully in a patient with steroid-resistant liver disease. Liver involvement can reveal systemic sarcoidois. Given the risk of progression to severe liver disease, it must be screened in all patients with systemic sarcoidosis. Treatment is not systematic, and still based on corticosteroid therapy. In the absence of prospective randomized controlled trials, the efficacy of UDCA need to be proven.

    Full Text Available Abstract Childhood sarcoidosis is a rare multisystemic granulomatous disorder of unknown etiology. In the pediatric series reported from the southeastern United States, sarcoidosis had a higher incidence among African Americans. Most reported childhood cases have occurred in patients aged 13–15 years. Macrophages bearing an increased expression of major histocompatibility class (MHC II molecules most likely initiate the inflammatory response of sarcoidosis by presenting an unidentified antigen to CD4+ Th (helper-inducer lymphocytes. A persistent, poorly degradable antigen driven cell-mediated immune response leads to a cytokine cascade, to granuloma formation, and eventually to fibrosis. Frequently observed immunologic features include depression of cutaneous delayed-type hypersensitivity and a heightened helper T cell type 1 (Th1 immune response at sites of disease. Circulating immune complexes, along with signs of B cell hyperactivity, may also be found. The clinical presentation can vary greatly depending upon the organs involved and age of the patient. Two distinct forms of sarcoidosis exist in children. Older children usually present with a multisystem disease similar to the adult manifestations, with frequent hilar lymphadenopathy and pulmonary infiltrations. Early-onset sarcoidosis is a unique form of the disease characterized by the triad of rash, uveitis, and arthritis in children presenting before four years of age. The diagnosis of sarcoidosis is confirmed by demonstrating a typical noncaseating granuloma on a biopsy specimen. Other granulmatous diseases should be reasonably excluded. The current therapy of choice for sarcoidosis in children with multisystem involvement is oral corticosteroids. Methotrexate given orally in low doses has been effective, safe and steroid sparing in some patients. Alternative immunosuppressive agents, such as azathioprine, cyclophosphamide, chlorambucil, and cyclosporine, have been tried in adult cases

    Sarcoidosis is a systemic disease that histologically typically shows non-caseating granulomas. The most common radiologic finding is hilar and mediastinal adenopathy. Patients with widely disseminated disease may show involvement of the peripheral appendicular skeleton in 1-13% of such cases. A primary skeletal presentation without other manifestations typical of the disease is rare. We present a case of sarcoidosis in a middle-aged Caucasian man in whom the disease presented with widespread lytic lesions in the axial skeleton and long bones, mimicking metastatic disease. There was no involvement of the peripheral skeleton, skin or lungs. (orig.)

  14. Common features of tuberculosis and sarcoidosis

    Full Text Available Tuberculosis (TB is a disease caused by Mycobacterium tuberculosis. Despite the availability of novel therapeutic approaches, TB is considered as one of the leading causes of death due to infectious diseases worldwide. Alveolar macrophages are the first line of defense against M. tuberculosis; they ingest and sequester the bacilli within granulomatous structures. Control and resolution of the infection requires activated T lymphocytes as well as Th1 cytokines. There are two forms of TB: active TB and latent TB. Latent TB is a state in which M. tuberculosis survives in the body without causing overt signs and symptoms. People with latent TB are noncontagious. However, M. tuberculosis can become active in the body, multiply, and cause overt TB. Sarcoidosis, on the other hand, is an autoimmune disease of unknown etiology which can affect multiple systems of the body. Nonspecific constitutional symptoms, such as fever, fatigue, malaise, and weight loss, are present in approximately one-third of patients. Chest X-ray usually shows hilar and mediastinal lymphadenopathy. Although the lungs are the most common sites of inflammation, sarcoidosis can also involve other organs, such as the eyes (intraocular and adnexal, skin, lymph nodes, salivary glands, heart, spleen, liver, and the nervous system. Recent investigations have provided further insights into the genetic basis of sarcoidosis and the way genotype determines the clinical presentation and phenotype of patients. Histopathologic features are usually insufficient for diagnosis of sarcoidosis. Diagnosis of sarcoidosis in endemic areas for TB can become a great challenge. Both TB and sarcoidosis are granulomatous diseases; TB is characterized by caseating granulomas, whereas sarcoidosis is characterized by noncaseating granulomas. New cases of sarcoidosis are increasingly being diagnosed in areas endemic for TB due to increased orientation of physicians and availability of diagnostic modalities

    2005-07-01

    Full Text Available Sarcoidosis is a multiorgan granulomatous disease, the most common head and neck manifestation of which is cervical lymphadenopathy. Only the presentation of sarcoidal granuloma in cervical lymph nodes without typical manifestations of systemic sarcoidosis poses a diagnostic difficulty. We describe the case of a 39-year-old male who had a 2-month history of a progressively increasing mass with soreness in his right neck. The biopsy from the neck mass demonstrated non-caseating epithelioid cell granuloma of the lymph nodes. The differential diagnoses of mycobacterial or fungal infections were excluded. Thoracic evaluations, including chest X-ray and high-resolution computed tomography, revealed no abnormal findings. Treatment with systemic corticosteroids resulted in improved clinical symptoms. No recurrence of the neck mass or other signs of systemic sarcoidosis were noted during 1.5 years of follow-up. Although our patient's definitive diagnosis could not be determined, the case highlights 2 important issues: sarcoidal granuloma in lymph nodes may be a precursor of sarcoidosis, even in the absence of pulmonary or other systemic involvement; and regular follow-up is recommended in such cases.

    Full Text Available Sarcoidosis is a chronic, multisystemic disease commonly affecting the lungs and lymphatic system and is characterized by the formation of noncaseating granulomas. Although several reports are available on cases developing both sarcoidosis and cancer metachronously, cases of simultaneous diagnosis of these diseases have rarely been reported. A 67-year-old woman diagnosed with endometrial cancer had developed systemic lymph node swelling, including bilateral hilar, paraaortic, and a few pelvic lymph nodes, as observed on preoperative imaging. During surgery, frozen sections of a paraaortic lymph node were examined, revealing noncaseating granulomas compatible with sarcoidosis. Next, modified radical hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymphadenectomy were performed. Postoperative pathological analysis revealed endometrioid adenocarcinoma of the uterus, and no metastasis but noncaseating granulomas were detected in the resected lymph nodes. Postoperatively, we identified cutaneous sarcoidosis and uveitis in the presence of a tuberculin-negative test. On the basis of these findings, we diagnosed the patients with endometrial cancer complicated by sarcoidosis. She underwent adjuvant chemotherapy, and at the 1-year follow-up, the lymph node swelling due to sarcoidosis was stable, and no recurrence of the cancer was observed. This turned out to be a case of early endometrial cancer mimicking advanced cancer by sarcoidosis. Histological confirmation and additional examination for sarcoidosis are necessary in cancer patients suspected of sarcoidosis.

    Full Text Available The association of sarcoidosis with multiple myeloma is not well known. Including this case report, 12 cases of patients with both sarcoidosis and multiple myeloma have been reported in the literature. The skeletal lesions of both conditions have many clinical and radiological similarities, and unless clinicians are aware of the association and the possibility of dual pathologies, the diagnosis of multiple myeloma in patients known with sarcoidosis may be missed. We present a case of a patient known with longstanding sarcoidosis who was found to have multiple lesions on magnetic resonance imaging (MRI involving the pelvis and both proximal femurs. Histological analysis revealed the presence of both non-necrotising granulomas consistent with sarcoidosis, and sheets of plasma cells consistent with a plasma cell neoplasm.

    Purpose Sarcoidosis is a non-caseating granulomatous disease for which a role for infectious antigens continues to strengthen. Recent studies have reported molecular evidence of mycobacteria or propionibacteria. We assessed for immune responses against mycobacterial and propionibacterial antigens in sarcoidosis bronchoalveolar lavage (BAL) using flow cytometry, and localized signals consistent with microbial antigens with sarcoidosis specimens, using matrix-assisted laser desorption ionization imaging mass spectrometry (MALDI-IMS). Methods BAL cells from 27 sarcoidosis, 14 PPD- controls, and 9 subjects with nontuberculosis mycobacterial (NTM) infections were analyzed for production of IFN-γ after stimulation with mycobacterial ESAT-6 and Propionibacterium acnes proteins. To complement the immunological data, MALDI-IMS was performed to localize ESAT-6 and Propionibacterium acnes signals within sarcoidosis and control specimens. Results CD4+ immunologic analysis for mycobacteria was positive in 17/27 sarcoidosis subjects, compared to 2/14 PPD-subjects, and 5/9 NTM subjects (p=00.008 and p=00.71 respectively, Fisher's exact test). There was no significant difference for recognition of P. acnes, which occurred only in sarcoidosis subjects that also recognized ESAT-6. Similar results were also observed for the CD8+ immunologic analysis. MALDI-IMS localized signals consistent with ESAT-6 only within sites of granulomatous inflammation, whereas P. acnes signals were distributed throughout the specimen. Conclusions MALDI-IMS localizes signals consistent with ESAT-6 to sarcoidosis granulomas, whereas no specific localization of P. acnes signals is detected. Immune responses against both mycobacterial and P. acnes are present within sarcoidosis BAL, but only mycobacterial signals are distinct from disease controls. These immunologic and molecular investigations support further investigation of the microbial community within sarcoidosis granulomas. PMID:22552860

    Ashu S Bhalla

    2017-01-01

    Full Text Available Sarcoidosis is a multi-systemic disorder of unknown etiology, although commonly believed to be immune-mediated. Histologically, it is characterized by noncaseating granuloma which contrasts against the caseating granuloma seen in tuberculosis (TB, an infectious disease that closely mimics sarcoidosis, both clinically as well as radiologically. In TB-endemic regions, the overlapping clinico-radiological manifestations create significant diagnostic dilemma, especially since the management options are markedly different in the two entities. Part 1 of this review aims to summarize the clinical, laboratory, and imaging features of sarcoidosis, encompassing both typical and atypical manifestations, in an attempt to distinguish between the two disease entities.

    2013-08-01

    Sarcoidosis is an autoimmune disease of unknown etiology characterized by the presence of non-caseating epithelioid cell granulomas in multiple organs. Cutaneous sarcoidosis occurs in approximately 25% of the cases. Sarcoid reactions on old scars, traumatized skin sites and around embedded foreign material have long been observed. For the past 70 years, sarcoidal granulomas on tattoos and permanent make-up have also been documented. Granulomatous and sarcoidal tattoo reactions may be the first and sometimes only cutaneous manifestation of systemic sarcoidosis. This review summarizes the currently available data on this topic and discusses the issues related to the diagnosis, management and physiopathogeny of sarcoidal reactions on tattoos.

    Cutaneous lesions of sarcoidosis present with various manifestations including specific and non-specific cutaneous lesions. Ichthyosiform sarcoidosis is a rare form of cutaneous sarcoidosis, presenting with asymptomatic, adherent, polygonal scales, mainly appearing on the lower limbs.  Ichthyosiform sarcoidosis has a predilection for dark-skinned races, and cases affecting Japanese patients have rarely been reported in English literature.  We herein describe three Japanese cases of ichthyosiform sarcoidosis on the lower limbs. All of the patients were female, with an age range of 57-69 years old.  Histologically, sarcoidal granulomas were located in the mid- to lower dermis.  All cases had scar sarcoidosis on the knees.  Furthermore, Case 1 presented with papular sarcoidosis on the back, and Case 3 presented with subcutaneous nodules on the buttock as well as erythema nodosum-like lesions on the lower legs.  All patients had lung sarcoidosis, but ocular sarcoidosis was seen in only Case 2. Case 3 showed Heerfordt syndrome with facial nerve paralysis. Histological features showed that the granular layers were scarcely detected in the overlying epidermis; however, filaggrin expression was not decreased.  Sarcoidal granulomas accumulated around the sweat glands in one case, whereas those features were not detected in the other two cases. In conclusion, ichthyosiform cutaneous sarcoidosis may be overlooked or misdiagnosed as xerotic dry skin which is frequently found in elderly people, and ichthyosiform cutaneous lesions may be more prevalent than previously estimated.

    Sarcoidosis is a systemic disease of unknown cause, characterized by widespread non-caseating granulomas. There is a wide spectrum of radiologic manifestations in pulmonary sarcoidosis, providing challenges to radiologists. However, recognition of the key features of sarcoidosis with knowledge of its pathologic background can often allow for specific diagnosis. In this review, we describe the variety of high-resolution CT findings in pulmonary sarcoidosis along with its pathologic features as the basis for radiographic manifestations, and discuss the key features on high-resolution CT for the specific diagnosis of pulmonary sarcoidosis.

    A 52-year-old man was admitted to our hospital with chief complaints of fever, general fatigue, and weight loss. A chest roentgenogram showed hyperinflation and many small nodular shadows in both lung fields. A chest CT scan showed centrilobular shadows distributed equally over all lung fields. Examination of a transbronchial lung biopsy specimen revealed a small non-caseating granuloma composed of a giant cell of Langhans type, epithelioid cells, and a few lymphocytes. There was a dark red eruption about 1 cm in diameter on the right forearm, which had been present for a few years, to the best of the patient's memory. Examination of a skin biopsy specimen revealed many non-caseating granulomas composed of epithelioid cells. Uveitis developed about 2 months after admission. Our diagnosis was sarcoidosis. Steroid therapy was started. The patient's symptoms rapidly disappeared and a chest roentgenogram showed remarkable improvement. We believe this was a very peculiar case of sarcoidosis: the patient had systemic symptoms only, and roentgenographic examinations showed hyperinflation and centrilobular shadows distributed over all lung fields.

  8. Evidence for local dendritic cell activation in pulmonary sarcoidosis

    2012-04-01

    Full Text Available Abstract Background Sarcoidosis is a granulomatous disease characterized by a seemingly exaggerated immune response against a difficult to discern antigen. Dendritic cells (DCs are pivotal antigen presenting cells thought to play an important role in the pathogenesis. Paradoxically, decreased DC immune reactivity was reported in blood samples from pulmonary sarcoidosis patients. However, functional data on lung DCs in sarcoidosis are lacking. We hypothesized that at the site of disease DCs are mature, immunocompetent and involved in granuloma formation. Methods We analyzed myeloid DCs (mDCs and plasmacytoid DCs (pDCs in broncho-alveolar lavage (BAL and blood from newly diagnosed, untreated pulmonary sarcoidosis patients and healthy controls using 9-color flowcytometry. DCs, isolated from BAL using flowcytometric sorting (mDCs or cultured from monocytes (mo-DCs, were functionally assessed in a mixed leukocyte reaction with naïve allogeneic CD4+ T cells. Using Immunohistochemistry, location and activation status of CD11c+DCs was assessed in mucosal airway biopsies. Results mDCs in BAL, but not in blood, from sarcoidosis patients were increased in number when compared with mDCs from healthy controls. mDCs purified from BAL of sarcoidosis patients induced T cell proliferation and differentiation and did not show diminished immune reactivity. Mo-DCs from patients induced increased TNFα release in co-cultures with naïve allogeneic CD4+ T cells. Finally, immunohistochemical analyses revealed increased numbers of mature CD86+ DCs in granuloma-containing airway mucosal biopsies from sarcoidosis patients. Conclusion Taken together, these finding implicate increased local DC activation in granuloma formation or maintenance in pulmonary sarcoidosis.

    Sarcoidosis is a systemic disease of unknown etiology, in which granulomas develop in various organs, including the skin, lungs, eyes, or heart. It has been reported that patients with sarcoidosis are more likely to develop panic disorder than members of the general population. However, there are many unknown factors concerning the causal relationship between these conditions. We present the case of a 57-year-old woman who appeared to have panic disorder, as she experienced repeated panic attacks induced by transient complete atrioventricular block, associated with cardiac sarcoidosis. Psychotherapy and pharmacotherapy were not effective in the treatment of her panic attacks. However, when we implanted a permanent pacemaker and initiated steroid treatment for cardiac sarcoidosis, panic attacks were ameliorated. Based on these findings, we diagnosed the patient's symptoms as an anxiety disorder associated with cardiac sarcoidosis, rather than panic disorder. This report highlights the importance of considering cardiac sarcoidosis in the differential diagnosis of panic disorder. This cardiac disease should be considered especially in patients have a history of cardiac disease (e.g., arrhythmia) and atypical presentations of panic symptoms. Panic disorder is a psychiatric condition that is typically diagnosed after other medical conditions have been excluded. Because the diagnosis of sarcoidosis is difficult in some patients, caution is required. The palpitations and symptoms of heart failure associated with cardiac sarcoidosis can be misdiagnosed as psychiatric symptoms of panic disorder. The condition described in the current case study appears to constitute a physical disease, the diagnosis of which requires significant consideration and caution.

    Sarcoidosis is a systemic granulomatous disease which predominantly affects the lungs, although granulomas can also involve all other organs, including the heart. Cardiac sarcoidosis (CS) may occur at any stage of the disease and may be the cause of sudden cardiac death, even in a previously asymptomatic patient. The aim of this study was to evaluate the incidence of CS in a large group of patients diagnosed or followed up due to sarcoidosis. We performed a retrospective analysis of patients at our institution discharged with the final diagnosis "sarcoidosis" (ICD-10: D86) from January 2008 to October 2012. Only those with biopsy (from respiratory tract or lymph nodes) confirmed diagnosis of sarcoidosis were included. We then selected the subset of patients with cardiac involvement due to sarcoidosis confirmed by positive magnetic resonance imaging. The study covered 1375 consecutive sarcoidosis patients (51 % men), who were hospitalized during 5 years. Multiorgan disease was detected in 160 cases (11.7 %), and cardiac involvement was found in 64 patients (4.7 % of all), 70.3 % of whom were men. Twelve of those with CS were in stage I, 48 in stage II, and four in stage III. The odds ratio for having cardiac involvement in men compared to women was 2.3 (95 % CI 1.36-4.0, p = 0.002). Cardiac involvement in sarcoidosis was diagnosed in the similar percentage as in previously published data but was significantly more frequently in men.

    Pulmonary sarcoidosis is a disorder characterized by noncaseating epithelioid granulomas that are anatomically distributed along lymphogenous routes. Currently, limited information is available about lymphangiogenesis in pulmonary sarcoidosis. To clarify the characteristics of lymphangiogenesis in pulmonary sarcoidosis. The concentrations of vascular endothelial growth factor (VEGF), VEGF-C, and VEGF-D in serum and bronchoalveolar lavage fluid from 65 patients with pulmonary sarcoidosis, 10 with idiopathic pulmonary fibrosis, and 29 healthy volunteers were measured by ELISA. Paraffin-embedded lung tissues obtained from 19 patients were used for immunohistochemical analyses, using primary antibodies against VEGF, VEGF-C, VEGF-D, podoplanin, VEGF receptor (VEGFR)-2, VEGFR-3, and CD73. The serum and bronchoalveolar lavage fluid concentrations of VEGF and VEGF-C were significantly increased in patients with pulmonary sarcoidosis. Immunohistochemical analysis showed that VEGF and VEGF-C were expressed in sarcoid granulomas. Immunostaining with anti-podoplanin antibody for the detection of lymphatic vasculatures showed the presence of usual lymphatics and atypical tubular structures around sarcoid granulomas. Atypical tubular structures were characterized by a thin membrane, with weak expression of podoplanin and a membrane deficit in a part of the borderline. The structures were observed in around 58.6% of the total of 193 granulomas, whereas usual lymphatics were limited in 15.6%. Atypical tubular structures were coexpressed with VEGFR-2, but not VEGFR-3, whereas VEGFR-3 was expressed in usual lymphatics. Part of the tubular structures was connected to CD73(+) afferent lymphatics. These results indicate the presence and the importance of heterogeneous lymphatic microvasculature around sarcoid granulomas in pulmonary sarcoidosis.

    Sarcoidosis is a systemic granulomatous disease that primarily affects the lung and lymphatic systems of the body. The diagnosis of sarcoidosis is established on the basis of compatible clinical and radiologic findings, supported by histologic evidence in one or more organs of noncaseating epithelioid-cell granulomas. A diagnosis of sarcoidosis is reasonably certain without biopsy in patients who present with Löfgren's syndrome. In confirmation of sarcoidosis scale lymph node biopsy, endobronchial biopsy, mediastinoscopy, blind tranbronchial needle aspiration and transbronchial lung biopsy or broncho-alveolar lavage were used with diagnostic yields between 60-85%. At present in stage I and II of sarcoidosis the novel technics such as Endoscopic ultrasound-guided, fine-needle aspiration of intrathoracic lymph nodes (EBUS-FNA) and esophageal ultrasound-guided fine-needle aspiration (EUS-FNA) are performed. The combination of these two methods has been reported to provide a diagnostic yield of above 83-90% with about 100% specificity and may obviate the need for mediastinoscopy.

    A 49-year-old man with cardiac sarcoidosis is presented. He suffered from congestive heart failure, and left ventricular asynergy and reduced function was evident by echocardiogram and left ventriculogram. A light microscopic examination of the endomyocardial biopsy revealed nonspecific myocarditis without giant cells or noncaseating granulomas. Under an electron microscope, however, several epithelioid cells were found in the specimen. The serum level of lysozyme was elevated. The patient had a past history of sarcoidosis of the eyes and lungs 22 years previously. Cardiac diseases presenting epithelioid cells other than sarcoidosis were clinically ruled out. Thus, the diagnosis of cardiac sarcoidosis was made based on both clinical and ultrastructural findings, and corticosteroid therapy was initiated. In the second biopsy, performed 4 months later, a noncaseating granuloma was found. Generally, the incidence of histological diagnosis of cardiac sarcoidosis by light microscopy is relatively low in endomyocardial biopsy specimens. The present case suggests that the addition of an ultrastructural examination may improve the diagnostic usefulness of the endomyocardial biopsy in cardiac sarcoidosis, since electron microscopy can clearly identify the presence of even one epithelioid cell.

  14. Recurrence of sarcoid granulomas in lung transplant recipients is common and does not affect overall survival

    Background: Sarcoidosis represents 2,5% of all indications for lung transplantation and criteria are generally assumed to be the same as for pulmonary fibrosis. Recurrence of granulomas in transplanted lungs has earlier been proved to derive from recipient immune cells, but its role in relation...... to lung function and overall survival after lung transplantation remains uncertain. Objective: To identify recurrent granuloma in transbronchial biopsies in patients receiving lung transplant because of sarcoidosis, and relate the findings to overall survival and lung function. Design: A total of 620...... patients were transplanted at this centre from 1992 until august 2012. This study comprised all patients (n=25) transplanted due to pulmonary sarcoidosis. Lung functions, trans-bronchial biopsies, and survival were compared in patients with and without recurrence of granulomas. Granulomas were defined...

    2015-10-01

    Full Text Available Sarcoidosis is a rare condition of granulomatous infiltration of many tissues of the body, including the heart. Cardiac sarcoidosis has been challenging to study, as it is often asymptomatic, although the initial presentation can be sudden cardiac death. The incidence and prevalence rates have been difficult to establish and no expert agreed upon guidelines for diagnosis and management of cardiac sarcoidosis exist, and clinical manifestations are varied. The pathophysiology of granuloma formation in the myocardium as well as other tissues is governed by immune response to some environmental antigen. Genetics is also thought to play a role, although gene alterations have not been extensively studied, and no specific set of genetic mutations has been identified to aid in identification of individuals at risk of developing disease. Epigenetic factors likely play a significant role in modulation of gene expression with respect to immune response. There is no standardized screening tool for the identification of cardiac sarcoidosis. The presence of systemic sarcoidosis and new-onset third-degree heart block or ventricular arrhythmias warrants further investigation for cardiac sarcoidosis. MRI and PET are useful in helping to identify cardiac sarcoidosis but are not stand-alone tests. Endomyocardial biopsy is the gold standard but has a low yield owing to the patchy nature of granuloma formation in the myocardium. Therapy should be instituted early and involves immunosuppressive therapy with predominant use of corticosteroids. Arrhythmias, either ventricular or high-grade heart blocks, are managed with device therapy. Clinical presentation may warrant use of antiarrhythmic agents and/or catheter ablation. Survival and disease prognosis are dependent on early diagnosis and treatment. This review details the current understanding of cardiac sarcoidosis and highlights diagnostic strategies and treatment with the aim of guiding the clinician to early

    Sarcoidosis is a systemic inflammatory disease of unknown etiology. Osteopontin (SPP1, OPN) is an extra cellular matrix glycoprotein and cytokine with a known role in granuloma formation and in autoimmune and inflammatory diseases. To determine whether plasma OPN levels are elevated in patients with sarcoidosis and compare the frequency of four single nucleotide polymorphism (SNPs) variants in the OPN gene in sarcoidosis patients compared to healthy controls. Demographic and clinical information, radiological studies and pulmonary function tests were evaluated in 113 patients with sarcoidosis and in 79 healthy controls. Blood samples were analyzed for SNPs of the OPN gene and for plasma OPN and CRP levels. Association between clinical features of disease and OPN levels as well as SNP frequencies was determined. Plasma OPN levels were higher in sarcoidosis patients than in healthy subjects, (median: 217 vs 122ng/ml, psarcoidosis patients and controls in the frequency of any of the SNPs evaluated. Presence of lung parenchymal involvement was associated with SNP distribution at rs1126772 (p = 0.02). We found no correlation between SNPs distribution and plasma OPN levels. Osteopontin protein levels are elevated in sarcoidosis. We found no evidence for an association between SNPs on the osteopontin gene and plasma OPN levels or the presence of sarcoidosis, however, an association between genotype and several phenotypic clinical parameters of disease was observed.

    To report, in vivo, on the quasi-histologic characteristics of a sarcoid choroidal granuloma as visualized by Enhanced Depth Imaging Spectral Domain Optical Coherence Tomography (EDI SD-OCT). A 49 year-old woman showing a choroidal granuloma secondary to sarcoidosis was imaged by EDI OCT. On EDI SD-OCT examination, sarcoid choroidal granuloma appears as a localized hyporeflectivechoroidalthickening. Two weeks after systemic corticosteroids, the thickness of the granuloma decreased from 568 μm to 356 μm. Five months later, it reached 274 μm, and after eleven months, it decreased to 150 μm. EDI SD-OCT allows direct visualization of choroidal granuloma secondary to sarcoidosis and evaluation of lesion regression after treatment.

    Presentation of the etiology, pathology, clinical course, radiology and differential diagnostics of skeletal sarcoidosis. Noncaseating epithelioid cell granulomas can trigger solitary, multiple or disseminated osteolysis, reactive osteosclerosis and/or granulomatous synovitis. The incidence of sarcoidosis is 10-12 per 100,000 inhabitants per year. Skeletal involvement is approximately 14 %. Skeletal involvement occurs almost exclusively in the stage of lymph node and pulmonary manifestation. Most cases of skeletal involvement are clinically asymptomatic. In the case of synovial involvement, unspecific joint complaints (arthralgia) or less commonly arthritis can occur. Typical skin alterations can be diagnostically significant. Punch out lesions osteolysis, coarse destruction and osteosclerosis can occur, which are best visualized with projection radiography and/or computed tomography. Pure bone marrow foci without interaction with the bone can only be detected with magnetic resonance imaging (MRI) and more recently with positron emission tomography (PET), mostly as incidental findings. There is a predeliction for the hand and trunk skeleton. Skeletal tuberculosis, metastases, multiple myeloma, Langerhans cell histiocytosis and sarcoid-like reactions in solid tumors must be differentiated. The key factors for correct diagnosis are thorax radiography, thorax CT and dermatological manifestations. (orig.)

    1983-10-01

    Sarcoidosis is a chronic systemic disease of unknown etiology characterized by non-caseating granulomatous inflammation of various organs. The records of 2319 patients with the diagnosis of sarcoidosis were reviewed to determine the incidence of nasal involvement. Seventeen patients or approximately 1% of the patients with sarcoidosis had histologically proven nasal mucosa involvement. These patients had symptoms of nasal crusting, congestion, epistaxis, pain, or anosmia. The clinical findings in these patients included friable nasal mucosa, nasal polyps, or a characteristic submucosal nodularity. Most patients also had abnormal sinus roentgenograms with either thickening of the sinus mucosa or opacification of the sinuses. Biopsy of the nasal mucosa shows typical non-caseating granulomas, but care must be exercised to exclude other causes of granulomatous inflammation of the nasal mucosa including tuberculosis, fungal infections, and other idiopathic granulomatous diseases such as Wegener's granulomatosis and Churg-Strauss syndrome. The treatment of nasal sarcoidosis has consisted of systemic steroids and in some cases topical beclomethasone dipropionate.

    Background Sarcoidosis is a chronic multisystem disease of unknown etiology characterized by noncaseating granulomas that most often involves the lungs, but frequently has extrapulmonary manifestations, which might be difficult to treat in individual patients. Objective To review different disease manifestations, focusing on extrapulmonary organ systems, and to provide treatment options for refractory cases. Materials and methods We performed a literature search using Medline and Google Scholar for individual or combined keywords of “sarcoidosis, extrapulmonary, treatment, kidney, neurosarcoidosis, cardiovascular, gastrointestinal, transplantation, musculoskeletal, rheumatology, arthritis, and skin”. Peer-reviewed articles, including review articles, clinical trials, observational trials, and case reports that were published in English were included. References from retrieved articles were also manually searched for relevant articles. Results and conclusion Isolated involvement of a single organ or organ system is rare in sarcoidosis, and thus all patients must be thoroughly evaluated for additional disease manifestations. Cardiac sarcoidosis and neurosarcoidosis may be life-threatening. Clinicians need to assess patients comprehensively using clinical, laboratory, imaging, and histopathological data to recommend competently the best and least toxic treatment option for the individual patient.

We present a 58-year-old African American man with a complicated medical history including long-standing sarcoidosis that has caused him chronic, unrelenting pain for two decades. He initially underwent placement of an intrathecal morphine pump, but recently began complaining of increasing pain. Consequently, he was seen at our hospital for interrogation of his pain pump by the interventional radiologist, and was incidentally noted to have bilateral calcified hilar lymphadenopathy on fluoroscopic imaging. A dedicated chest x-ray confirmed the abnormality, which was consistent with his known diagnosis of sarcoidosis. Sarcoidosis is a complex disease process characterized by noncaseous granulomas that can affect various organ systems, with pulmonary involvement in up to 90% of cases (1. Though sarcoidosis is a diagnosis of exclusion, clinicians should recognize that bilateral hilar lymphadenopathy is highly concerning for the underlying noncaseating granulomatous disease (2.

    Sarcoidosis is a granulomatous disorder of unknown cause characterized by non-caseating granuloma in young adults. Cardiac involvement is rare and range from 2 to 75% depending on diagnostic criteria. Cardiac involvement in sarcoidosis may be asymptomatic or may manifest as rhythm/conduction troubles or congestive heart failure. The diagnosis and treatment of cardiac sarcoidosis may be challenging. However, advances have come in recent years from the use of cardiac MRI and 18FDG-TEP scanner, as well as from the stratification of the risk of ventricular tachycardia/fibrillation. Due to the rarity of the disease, there is no reliable prospective large study to guide therapeutic strategy for cardiac sarcoidosis. Corticosteroids are probably efficacious, in particular in case of atrio-ventricular block or moderate heart failure. Immunosuppressive drugs have not been largely studied but methotrexate could be helpful. In refractory forms, TNF-α antagonists have been used with success.

    Abstract Sarcoidosis is a granulomatous disease that most frequently affects the lungs with pulmonary infiltrates and/or bilateral hilar and mediastinal lymphadenopathy. An association of sarcoidosis and lymphoproliferative disease has previously been reported as the sarcoidosis-lymphoma syndrome. Although this syndrome is characterized by sarcoidosis preceding lymphoma, very few cases of sarcoidosis following lymphoma have been reported. We describe the clinical, biological, and radiological characteristics and outcome of 39 patients presenting with sarcoidosis following lymphoproliferative disease, including 14 previously unreported cases and 25 additional patients, after performing a literature review. Hodgkin lymphoma and non-Hodgkin lymphoma were equally represented. The median delay between lymphoma and sarcoidosis was 18 months. Only 16 patients (41%) required treatment. Sarcoidosis was of mild intensity or self-healing in most cases, and overall clinical response to sarcoidosis was excellent with complete clinical response in 91% of patients. Sarcoidosis was identified after a follow-up computerized tomography scan (CT-scan) or 18fluorodeoxyglucose-positron emission tomography/computerized tomography (18FDG-PET/CT) evaluation in 18/34 patients (53%). Sarcoidosis is therefore a differential diagnosis to consider when lymphoma relapse is suspected on a CT-scan or 18FDG-PET/CT, emphasizing the necessity to rely on histological confirmation of lymphoma relapse.

    Objective: To analyze radiological findings observed at high-resolution computed tomography in patients with sarcoidosis, and establishing their correlation with pathological findings. Materials and Methods: High-resolution computed tomography findings in ten patients with sarcoidosis were reviewed and correlated with findings in specimens obtained by surgical biopsy or at necropsy of four of such patients. Results: The most frequently observed finding was presence of nodules with perilymphatic distribution, predominating along bronchovascular sheaths and pleural surface, with subpleural nodules and nodular scissurae. Other less frequent findings were ground-glass attenuation and interlobular septa thickening. Conclusion: In general, all the mentioned findings demonstrated anatomopathological correlation with development of granulomas in these regions. (author)

    Sarcoidosis is a multisystem granulomatous disorder of unknown aetiology. The diagnosis is suggested on the basis of wide ranging clinical and radiological manifestations, and is supported by the histological demonstration of non-caseating granulomas in affected tissues. This review highlights the multisystem radiological features of the disease across a variety of imaging methods including multidetector computed tomography (CT), magnetic resonance imaging (MRI) as well as functional radionuclide techniques, particularly 2-[{sup 18}F]-fluoro-2-deoxy-D-glucose (FDG) positron emission tomography/computed tomography (PET/CT). It is important for the radiologist to be aware of the varied radiological manifestations of sarcoidosis in order to recognize and suggest the diagnosis in the appropriate clinical setting.

    Full Text Available A 59-year-old woman with a history of lung sarcoidosis developed general edema and exertional dyspnea. An electrocardiogram showed first-degree atrioventricular block with complete right bundle branch block. Chest X-ray showed cardiomegaly. Echocardiography showed diffuse and severe hypokinesis of the left ventricle (LV and biventricular enlargement with severe tricuspid regurgitation. Myocardial scintigraphy disclosed a perfusion defect at the ventricular septum and hypoperfusion at the posterior wall and the apex. On cardiac catheterization, pulmonary capillary wedge pressure, right ventricular, and right atrial pressures were elevated. Coronary angiograms were normal. Myocardial biopsy of the right ventricle histologically revealed epithelioid cell granuloma with infiltration of fibrous cells. The patient's symptom and LV function were improved with conventional medical therapy for heart failure. This is a rare case of cardiac sarcoidosis resulting in biventricular failure.

    Cutaneous silica granuloma is a poorly understood, uncommon condition that may mimic cutaneous sarcoidosis. We describe two cases of this entity and their characteristic latency period (between the time of silica exposure to the time of clinical onset of granuloma). We also review the histologic and energy dispersive x-ray analysis data, which prove the diagnosis. This condition should be recognized as an occupational dermatosis as well as the result of past incidental cuts or abrasions, which result in the development of granulomas, many in old wound scars. Differentiation from cutaneous sarcoidosis is possible with polarized light microscopy and energy-dispersive x-ray analysis.15 references.

    Core-needle biopsy guided by ultrasound can be performed for investigating peripheral lymph node (PLN). The aim of this study was to determine the efficacy of this technique in sarcoidosis. Retrospective review of files of all patients in the database of the radiology department of Avicenne university hospital who underwent PLN biopsies guided by ultrasound from January 2008 to June 2011 (n=292). Cases with either granulomas at histology with the procedure or with a final diagnosis of sarcoidosis were included in the study. The histological specimens were adequate in 282 out of 292 cases (96%) showing non-caseating granulomas in 22 cases (n=20 patients with a final diagnosis of sarcoidosis and n=2 patients with tuberculosis). After reviewing clinical files of the 282 patient, 22 were confirmed to have sarcoidosis, at initial presentation (n=19) or later during flare-up or relapse (n=3) with only 2 patients having no granuloma on PLN biopsy. PLN were palpable in 18 cases and only detected by (18F)FDG-PET/CT showing increased PLN uptake in 4 cases. The sensitivity and specificity of adequate biopsy were 91 and 99% and the positive and negative predictive values were 91 and 99%, respectively. Core-needle biopsy guided by ultrasound has a high efficacy for evidencing granulomas in sarcoidosis patients with PLN involvement either clinically palpable or in the presence of (18F)FDG-PET/CT uptake.

    Increased {sup 18}F-fluorodeoxyglucose (FDG) uptake in inflammatory lesions, particularly in granulomatous inflammation (e.g., sarcoidosis), makes it difficult to differentiate malignant tumors from benign lesions and is the main source of false-positive FDG-PET findings in oncology. Here, we developed a rat granuloma model and examined FDG uptake in the granuloma. The effects of corticosteroid on FDG uptake in the granuloma were compared with those in a malignant tumor. Rats were inoculated with Mycobacterium bovis bacillus Calmette-Guerin (BCG) or allogenic hepatoma cells, and subdivided into control and pretreated (methylprednisolone acetate, 8 mg/kg i.m.) groups. Radioactivity in tissues was determined 1 h after the FDG injection. FDG-PET was performed in rats bearing BCG granulomas or tumors before and after prednisolone treatment. Mature epithelioid cell granuloma-formation and massive lymphocyte-infiltration were observed in the control group of granuloma, histologically similar to sarcoidosis. The mean FDG uptake in the granuloma was comparable to that in the hepatoma. Prednisolone reduced epithelioid cell granuloma-formation and lymphocyte-infiltration. Prednisolone significantly decreased the level of FDG uptake in the granuloma (52% of control), but not in the hepatoma. The FDG uptake levels in the granulomas and tumors were clearly imaged with PET. We developed an intramuscular granuloma rat model that showed a high FDG uptake comparable to that of the tumor. The effect of prednisolone pretreatment on FDG uptake was greater in the granuloma than in the tumor. These results suggest that BCG-induced granuloma may be a valuable model and may provide a biological basis for FDG studies. (orig.)

    Cardiac involvement in systemic sarcoidosis sometimes provokes life-threatening ventricular tachyarrhythmia. Steroid administration is one of the fundamental anti-arrhythmia therapies. For an indication of steroid therapy, a definitive diagnosis of sarcoidosis is required.1) However, cases that are clearly suspected of cardiac sarcoidosis based on their clinical courses sometimes do not meet the current diagnostic criteria and result in the loss of an appropriate opportunity to perform steroid therapy.Here we report a case that was diagnosed as sarcoidosis by incidental biopsy of an inguinal lymph node during cardiac resuscitation for cardiac tamponade.2) While the inguinal lymph node was not swollen on computed tomography, a specimen obtained from an incidental biopsy during the exposure of a femoral vessel for the establishment of extracorporeal cardio-pulmonary resuscitation showed a non-caseating granuloma.This findings suggest a non-swelling lymph node biopsy might be an alternative strategy for the diagnosis for sarcoidosis if other standard strategies do not result in a diagnosis of sarcoidosis.

    Sarcoidosis is a systemic disease characterized by the formation of granulomas in various organs, mainly lungs and lymphatic system. Joint, muscle, and bone involvement is also rather common. Recent studies on its pathogenesis and therapeutic management are reviewed here. The pathogenesis of sarcoidosis is not fully elucidated. An exaggerated granulomatous reaction after exposure to unidentified antigens in genetically susceptible individuals evokes a clinical situation which we call sarcoidosis. No firm guidelines exist on whether, when, and how treatment should be started. Treatment is dependent on the presentation and the distribution, extensiveness and severity of sarcoidosis. Treatment of Löfgren's triad-related symptoms starts with NSAIDs; in other more extensive manifestations of sarcoidosis, the initiating dosage of glucocorticosteroids is approximately 20 mg daily. In terms of evidence-based treatment for sarcoidosis, only a few randomized controlled trials have been done. There is no cure for chronic sarcoidosis, and treatment only changes the granulomatous process and its clinical consequences. Identified associations of certain polymorphisms with severity of the disease and treatment response suggest future research questions as well as finding the cause(s) of sarcoidosis, and the elucidation of relevant biomarkers and new efficient treatments. Between 20 and 70% of patients need systemic therapy. The increased awareness of long-term side-effects of glucocorticosteroids and the emergence of new drugs have changed the treatment of sarcoidosis. Alternative or additional options to corticosteroids should be assessed.

    2016-11-01

    Numerous biomarkers have been evaluated for the diagnosis, assessment of disease activity, prognosis, and response to treatment in sarcoidosis. In this report, we discuss the clinical and research utility of several biomarkers used to evaluate sarcoidosis. Areas covered: The sarcoidosis biomarkers discussed include serologic tests, imaging studies, identification of inflammatory cells and genetic analyses. Literature was obtained from medical databases including PubMed and Web of Science. Expert commentary: Most of the biomarkers examined in sarcoidosis are not adequately specific or sensitive to be used in isolation to make clinical decisions. However, several sarcoidosis biomarkers have an important role in the clinical management of sarcoidosis when they are coupled with clinical data including the results of other biomarkers.

  19. Immune response CC Chemokines, CCL2 and CCL5 are associated with Pulmonary Sarcoidosis

    Palchevskiy, Vyacheslav

    2011-04-04

    Abstract Background Pulmonary sarcoidosis involves an intense leukocyte infiltration of the lung with the formation of non-necrotizing granulomas. CC chemokines (chemokine (C-C motif) ligand 2 (CCL2)-CCL5) are chemoattractants of mononuclear cells and act through seven transmembrane G-coupled receptors. Previous studies have demonstrated conflicting results with regard to the associations of these chemokines with sarcoidosis. In an effort to clarify previous discrepancies, we performed the largest observational study to date of CC chemokines in bronchoalveolar lavage fluid (BALF) from patients with pulmonary sarcoidosis. Results BALF chemokine levels from 72 patients affected by pulmonary sarcoidosis were analyzed by enzyme-linked immunosorbent assay (ELISA) and compared to 8 healthy volunteers. BALF CCL3 and CCL4 levels from pulmonary sarcoidosis patients were not increased compared to controls. However, CCL2 and CCL5 levels were elevated, and subgroup analysis showed higher levels of both chemokines in all stages of pulmonary sarcoidosis. CCL2, CCL5, CC chemokine receptor type 1 (CCR1), CCR2 and CCR3 were expressed from mononuclear cells forming the lung granulomas, while CCR5 was only found on mast cells. Conclusions These data suggest that CCL2 and CCL5 are important mediators in recruiting CCR1, CCR2, and CCR3 expressing mononuclear cells as well as CCR5-expressing mast cells during all stages of pulmonary sarcoidosis.

    Inclusion body myositis is a form of inflammatory myopathy. We identified 4 cases of inclusion body myositis showing granuloma formation in muscle tissue and aimed to assess the features of this atypical form of inclusion body myositis. We retrospectively reviewed consecutive patients who satisfied European Neuromuscular Centre IBM Research Diagnostic Criteria 2011. Then, we assessed clinical profiles and pathological findings in patients with inclusion body myositis with granuloma and compared these findings with those of typical inclusion body myositis without granuloma. We identified 15 patients with inclusion body myositis. Four patients showed granuloma formation in muscle tissue in addition to typical pathological features of inclusion body myositis. Granulomas comprised a mixture of inflammatory cells, such as macrophages, epithelioid histiocytic cells, and lymphocytes. One patient was found to have mediastinal granulomatous lymphadenopathy; however, the evidence in other patients was insufficient for a diagnosis of systemic sarcoidosis. There were no significant differences between groups with and without granuloma regarding clinical manifestations, laboratory findings, response to immunomodulating therapies, or myopathological profiles. We established a new form of inclusion body myositis showing granuloma formation in muscle tissue. Inclusion body myositis and granuloma formation could have identical pathomechanisms concerning dysregulation of autophagy. Copyright © 2015 Elsevier B.V. All rights reserved.

    Sarcoidosis is a multisystemic immune disorder of unknown cause characterized by the formation of epithelioid granuloma in involved organs particularly the lung and the lymphatic system. Consistent recent advances have been made on the clinical, therapeutical and pathogenetic aspects. Various clinical phenotypes are better characterized and efforts to grade the severity could facilitate genetic studies and therapeutic trials. Pulmonary hypertension and some infrequent or atypical pulmonary manifestations as well as some rare extrapulmonary localizations have been thoroughly studied. Sarcoidosis-like granulomatosis due to identified causes constitute interesting models and have to be differentiated from sarcoidosis. THERAPEUTICAL ASPECTS: Anti-TNFalpha drugs have been investigated and infliximab has been proved efficient even though some limits to its efficiency have to be taken into account. PATHOGENETIC ASPECTS: Finally, advances concerning the pathogenesis, particularly genetic predisposing factors and phenotype/genotype correlations have been made.

    The antigen pathway of cutaneous sarcoidosis remains obscure. We have investigated topographic involvement of inflammatory cells and lymphatic vessels. Eleven cutaneous biopsies from eight patients were studied, along with controls from other granulomatous disorders and various skin lesions. Markers for lymphocytes, dendritic cells (DCs), and lymphatic vessel endothelial cells were detected using immunohistochemistry. S100(+) and CD1a(+) immature DCs (Langerhans cells) occurred more frequently within the epidermis, whereas S100(+), fascin(+), or CD83(+) maturing DCs occurred more frequently beneath the epithelium in cutaneous sarcoidosis cases than in controls (e.g. CD83, cutaneous sarcoidosis vs. other granulomatous disorders: r = 0.557, p = 0.011). Fascin(+) and CD83(+) mature DCs were often closely attached to CD3(+) T-lymphocytes around dermal granulomas. D2-40(+) lymphatic vessels were often found surrounding dermal granulomas, especially those located in the deeper dermis, in contrast to fascin(+) blood vessels. Antigen-capturing by immature DCs seems to take place initially in the epidermis, followed by maturation of DCs. These mature DCs may present the processed antigen to T-lymphocytes that cause dermal granulomas either in the interstitium of the upper dermis, or in or around lymphatic vessels of the lower dermis. Environmental antigen could be verified by skin test.

    Sarcoidosis is characterized by noncaseating granulomas with an unknown cause that present primarily in the lung. Propionibacterium acnes, an immunogenic commensal skin bacterium involved in acne vulgaris, has been implicated as a possible causative agent of sarcoidosis. Here, we demonstrate that a viable strain of P. acnes isolated from a patient with sarcoidosis and instilled intratracheally into wild-type mice can generate pulmonary granulomas similar to those observed in patients with sarcoidosis. The formation of these granulomas is dependent on the administration of viable P. acnes. We also found that mice deficient in the innate immunity adapter protein MyD88 had a greater number and a larger area of granuloma lesions compared with wild-type mice administered P. acnes. Early after P. acnes administration, wild-type mice produced proinflammatory mediators and recruited neutrophils into the lung, a response that is dependent on MyD88. In addition, there was an increase in granuloma number and size after instillation with P. acnes in mice deficient in CybB, a critical component of nicotinamide adenine dinucleotide phosphate oxidase required for the production of reactive oxygen species in the phagosome. Myd88 -/- or Cybb -/- mice both had increased persistence of P. acnes in the lung, together with enhanced granuloma formation. In conclusion, we have generated a mouse model of early granuloma formation induced by a clinically relevant strain of P. acnes isolated from a patient with sarcoidosis, and, using this model, we have shown that a deficiency in MyD88 or CybB is associated with impaired bacterial clearance and increased granuloma formation in the lung.

    Sarcoidosis is known to be involved in diseases with vasculitis as sarcoid vasculitis. However, vasculitis in cutaneous sarcoidal lesions is extremely rare. Here we describe a case of sarcoidosis with multiple annular skin lesions with granulomatous vasculitis. A 62-year-old female was diagnosed with sarcoidosis by chest-abdominal computed tomographic examination and laboratory tests. The skin lesions had appeared on her lower limbs 2 years before. Physical examination showed multiple infiltrated annular eruptions on the lower extremities. A skin biopsy of an area of erythema showed multiple non-caseating epithelioid cell granulomas in the dermis and subcutaneous fat and granulomatous vasculitis with fibrinoid degeneration in the subcutaneous fat. There are two types of vasculitis in sarcoidosis: leukocytoclastic and granulomatous vasculitis. Ulcers and livedo were more common in granulomatous vasculitis than in leukocytoclastic vasculitis. The present case had unique annular skin lesions of sarcoidosis with granulomatous vasculitis. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Abstract Background Sarcoidosis is a multisystem disease of unknown origin characterized by the formation of noncaseating granulomas, in particular in the lungs, lymph nodes, eyes, and skin. Systemic treatment for cutaneous sarcoidosis can be used for large disfiguring lesions, generalized involvement, or recalcitrant lesions that did not respond to topical therapy. Case presentations We report three patients with recalcitrant cutaneous sarcoidosis who were treated with oral fumaric acid esters (FAE. Three female patients presented with cutaneous sarcoidosis that have proved to be refractory to various therapies, including corticosteroids and chloroquine. We treated the patients with FAE in tablet form using two formulations differing in strength (Fumaderm® initial, Fumaderm®. Dosage of FAE was performed according to the standard therapy regimen for psoriasis patients. After treatment with FAE (4–12 months, a complete clearance of skin lesions was achieved in the three patients. The side effects observed in this trial correspond to the well-known spectrum of adverse effects of FAE (flush, minor gastrointestinal complaints, lymphopenia. Conclusions On the basis of our findings FAE therapy seems to be a safe and effective regimen for patients with recalcitrant cutaneous sarcoidosis. Nevertheless further investigations are necessary to confirm our preliminary results.

    Sarcoidosis is a multi-system inflammatory disorder characterized by the presence of non-caseating granulomas in involved organs. Patients with sarcoidosis have a reduced quality-of-life and are at an increased risk for several comorbidities. Little is known about the direct and indirect cost of sarcoidosis following the initial diagnosis. To provide an estimate of the healthcare resource utilization (HCRU) and costs borne by commercial payers for sarcoidosis patients in the US. Patients with a first diagnosis of sarcoidosis between January 1, 1998 and March 31, 2015 ("index date") were selected from a de-identified privately-insured administrative claims database. Sarcoidosis patients were required to have continuous health plan enrollment 12 months prior to and following their index dates. Propensity-score (1:1) matching of sarcoidosis patients with non-sarcoidosis controls was carried out based on a logistic regression of baseline characteristics. Burden of HCRU and work loss (disability days and medically-related absenteeism) were compared between the matched groups over the 12-month period following the index date ("outcome period"). A total of 7,119 sarcoidosis patients who met the selection criteria were matched with a control. Overall, commercial payers incurred $19,714 in mean total annual healthcare costs per sarcoidosis patient. The principle cost drivers were outpatient visits ($9,050 2015 USD, 46%) and inpatient admissions ($6,398, 32%). Relative to controls, sarcoidosis patients had $5,190 (36%) higher total healthcare costs ($19,714 vs $14,524; p economic burden to payers in the first year following diagnosis.

    2014-01-01

    Sarcoidosis is a multisystem inflammatory disorder of unknown cause. It most commonly affects the pulmonary system but can also affect the musculoskeletal system, albeit less frequently. In patients with sarcoidosis, rheumatic involvement is polymorphic. It can be the presenting symptom of the disease or can appear during its progression. Articular involvement is dominated by nonspecific arthralgia, polyarthritis, and Löfgren's syndrome, which is defined as the presence of lung adenopathy, arthralgia (or arthritis), and erythema nodosum. Skeletal manifestations, especially dactylitis, appear mainly as complications of chronic, multiorgan sarcoidosis. Muscle involvement in sarcoidosis is rare and usually asymptomatic. The diagnosis of rheumatic sarcoidosis is based on X-ray findings and magnetic resonance imaging findings, although the definitive diagnosis is made by anatomopathological study of biopsy samples. Musculoskeletal involvement in sarcoidosis is generally relieved with nonsteroidal anti-inflammatory drugs or corticosteroids. In corticosteroid-resistant or -dependent forms of the disease, immunosuppressive therapy, such as treatment with methotrexate or anti-TNF-α, is employed. The aim of this review was to present an overview of the various types of osteoarticular and muscle involvement in sarcoidosis, focusing on their diagnosis and management. PMID:24831403

    2017-10-01

    Full Text Available Oral vegetable granuloma represents an inflammatory lesion of foreign body origin resulting from the implantation of vegetable matter. Controversy regarding its pathogenesis is reflected by the various terminologies used to describe the lesion. Its diverse clinical presentations are due to variations in the antigenic potential of the vegetable material and the host response. As the diagnosis is solely histopathological, it is critical to differentiate vegetable granuloma from other oral granulomatous lesions like tuberculosis, sarcoidosis and Wegner’s granulomatosis. Here, we report six cases with the varied clinicopathological presentation of hyaline ring granulomas in association with different pathological lesions.

    Sarcoidosis is a systemic disease of unknown cause characterized by the formation of immune granulomas which most often involve the lung and the lymphatic system. Sarcoidosis may encompass numerous different clinical presentations. Typical presentations often prompt a rapid diagnosis while in 25 to 50% of cases, diverse and less typical presentations may lead to delayed diagnosis. The mediastinopulmonary sphere is involved in 85 to 95% of cases, associated with extrapulmonary localizations in half of cases while extrapulmonary localizations without lung involvement may be seen in 5 to 15% of cases. Bilateral hilar lymphadenopathy is the most typical sign at chest radiography. Computed tomography (CT) is essential face for atypical manifestations of the disease to avoid confusion with differential diagnoses and, sometimes, comorbidities. CT typically evidences diffuse pulmonary perilymphatic micronodules, with a perilobular and fissural distribution and upper and posterior predominance, even when an atypical CT pattern is predominant. CT allows deciphering pulmonary lesions in cases of pulmonary fibrosis, pulmonary hypertension, and airflow limitation. Pulmonary function tests generally correlate with the overall disease process. Forced vital capacity is the simplest and most accurate parameter to reflect the impact of pulmonary sarcoidosis. Cardiopulmonary exercise testing helps in understanding the mechanism behind dyspnea of uncertain origin. Endoscopic transbronchial needle aspiration is an extra tool to support diagnosis in addition to more classical biopsy means. Bronchoalveolar lavage (BAL) may be used for individual patients while it is not really decisive for the diagnosis of sarcoidosis for most patients. Diagnosis relies on compatible clinical and radiological presentation, evidence of noncaseating granulomas and exclusion of other diseases with a similar presentation or histology. The probability of diagnosis at presentation is variable from case to case

    Full Text Available Here, we report a patient with sarcoidosis who developed edematous erythema and interstitial lung disease. At the initial visit, clinically amyopathic dermatomyositis (CADM with rapidly progressive interstitial lung disease (RP-ILD was suspected because he had progressive dyspnea but no muscle weakness. The presence of anti-CADM-140/MDA5 autoantibodies was immediately assessed to facilitate a precise diagnosis, with negative results. Thereafter, skin and transbronchial lung biopsies revealed noncaseating granuloma with Langhans giant cells in both specimens, leading to a diagnosis of sarcoidosis. In this case, clinical features of skin and lung were unable to distinguish DM (including CADM from sarcoidosis, but the lack of anti-CADM-140/MDA5 antibody was useful for differentiating CADM with RP-ILD mimicking sarcoidosis from bona fide sarcoidosis.

    Opportunistic infections (OI) are uncommon in sarcoidosis (1 to 10%) and mostly occur in patients with previously diagnosed disease or can rarely be the presenting manifestation. The most common OIs are, in descending order: aspergillosis, cryptococcosis, and mycobacterial infections. Treatment with corticosteroids is the most frequent risk factor for OI occurrence during sarcoidosis but immunosuppressive drugs and therapy with anti-TNFα are also risk factors. Overall, clinical presentation, treatment, and outcome are identical to that occur in other conditions complicated with the occurrence of OIs. However, some atypical presentations of OIs can mimic sarcoidosis exacerbation and misdiagnosis may lead clinicians to increase immunosuppression, causing worsening of the OI. The meticulous collection of patient's history along with factors differentiating OI from sarcoidosis exacerbation is key factor to optimally manage these patients.

    Full Text Available Intraorbital sarcoidosis presenting externally as a solitary eyelid mass has been described in the literature as isolated case reports. We describe a rare case of asymptomatic sarcoidosis with orbital mass as the presenting feature in a young woman. The lesion was excised with the clinical possibility of a thrombosed varix. On histology, the lesion was characterized by numerous nonnecrotizing epithelioid cell granulomas with several multinucleated giant cells containing abundant asteroid bodies and oxalate crystals. No tubercular bacilli were detected. A diagnosis of sarcoidosis was rendered and on further clinical work-up, she was detected to have hilar lymphadenopathy. Sarcoidosis should be considered in the differential diagnosis of orbital mass as it could be the initial manifestation of the disease process.

    Full Text Available Abstract Background Sarcoidosis is a chronic, systemic granulomatous disease of unknown etiology that features noncaseating granulomas in many body regions. Sinonasal involvement is rare but is also suspected to be underreported. Case presentation We present the case of a 39-year-old woman who was incidentally diagnosed with isolated sarcoidosis involving the middle turbinates. Histopathologic examination of resected concha bullosa material and an extensive panel of diagnostic tests revealed a diagnosis of isolated sarcoidosis. Since no systemic manifestations were detected, topical corticosteroid (nasal spray was administered in the postoperative period. Throughout the 12 months after surgery, the patient remained free of symptoms and all nasal endoscopy examinations were normal. Conclusion Although isolated nasal involvement of sarcoidosis is rare, otorhinolaryngologists should consider this condition in a differential diagnosis for sinonasal complaints.

    HLA-G expression was investigated by immunohistochemistry in granulomas from sarcoidosis patients, weak HLA-G expression was observed in only one patient. CONCLUSIONS: HLA-G alleles that include a 14-bp sequence polymorphism in exon 8 of the HLA-G gene are observed more often in sarcoidosis patients......BACKGROUND: The MHC class Ib molecule Human Leukocyte Antigen (HLA)-G may be important in induction and maintenance of immunological tolerance, and HLA-G expression may have a role in different cancers, in certain diseases with associations to HLA, and in organ transplantation. Sarcoidosis...... is a systemic granulomatous disease with unknown etiology but at the molecular level several studies have shown HLA associations. METHODS: In the present study, HLA-G alleles/polymorphisms were studied in sarcoidosis patients (n = 47) and controls (n = 129) by PCR techniques and HLA-G protein expression...

    Sarcoidosis is a systemic idiopathic disease characterized by the presence of noncaseating epithelioid granulomas in multiple organs. Thoracic involvement occurs in nearly all patients at some time during the course of the disease. We describe the findings in our patients with this disease using conventional computed tomography (CT) and high resolution CT (HRCT). We analyzed retrospectively the CT studies performed in our unit in 43 patients diagnosed as having sarcoidosis on the basis of biopsy and/or bronchoalveolar lavage. We classified the findings according to their intra parenchymal or extra parenchymal location, observing infrequent features such as pleural and pericardial thickening, lymphadenopathies presenting calcification or at uncommon sites, splenomegaly, laveolar pattern, trabecular pattern and air trapping. In patients with sarcoidosis, conventional CT and HRCT are more useful than plain radiology for the detection and study of the extension of intra parenchymal and extra parenchymal lesions and for the assessment of the disease course. It also serves to guide trans thoracic biopsy, should this procedure be necessary. (Author) 11 refs.

    Data on clinical manifestations and outcome of hepatic sarcoidosis are scarce. This study aimed to use a population-based cohort of patients with incident sarcoidosis to better describe the characteristics of hepatic sarcoidosis. A cohort of incident cases of sarcoidosis in Olmsted County, MN, USA, from 1976 to 2013 was identified from the database. Diagnosis was verified by individual medical record review. Confirmed cases of sarcoidosis were then reviewed for liver involvement. Data on clinical manifestations, imaging study, liver biochemical tests, treatment, and outcome were collected. Cumulative incidence of cirrhosis adjusted for the competing risk of death was estimated. A total of 345 cases of incident sarcoidosis were identified. Of these, 19 cases (6%) had liver involvement (mean age 46.1 years, 53% female and 79% Caucasian). Most patients had asymptomatic liver disease and were discovered in pursuit of abnormal biochemical tests and imaging studies. Alkaline phosphatase (ALP) and gamma-glutamyl transferase (GGT) were elevated in the majority of patients (88 and 90%, respectively). Elevated transaminases were less common and less severe. About half of patients had abnormal imaging study with hypodense nodular lesions being the most common abnormality (six patients) followed by hepatomegaly (three patients). Liver biopsy revealed non-caseating granuloma in 88% (14 of 16 patients). A total of four patients developed cirrhosis. Involvement of the liver by sarcoidosis was seen in 6% of patients with sarcoidosis. The majority of patients were asymptomatic. Elevated ALP and GGT were the most common abnormal biochemical tests. Liver biopsy revealed non-caseating granuloma in almost all cases. Cirrhosis was seen in a significant number of patients. Generalizability of the observations to other populations may be limited, as the studied population was predominantly Caucasian. The prevalence of liver disease may be higher in more diverse populations.

    Vocal process granuloma or contact ulcer is uncommon disease in which there is chronic irritation and granulation tissue formation at the posterior third of the vocal folds. Thirteen patients (11 men and two women) with vocal process granuloma were enrolled in this study; cases of intubation granuloma were excluded. The most frequent complaints were throat irritation, frequent throat clearing and voice change. Forty-seven percent of patients had a recurrence two to four months after surgery. Computed tomography (CT) of the larynx in four patients showed arytenoid sclerosis on the involved side and disclosed moderate enhancement of the vocal fold granuloma after contrast injection in one. Three patients had hyperacidity and four had hyperfunctioning granulomas: two used their voices excessively and the other two had bilateral sulcus vocalis. To our knowledge this is the first report of sulcus vocalis with vocal process granuloma, and of enhanced vocal process granuloma.

    Full Text Available Sarcoidosis is a systemic chronic granulomatous disease of unknown etiology. It predominantly involves the lungs but can affect many organs or tissues in the body, such as the lymphatic system, skin, eyes, and liver. Typical histopathological lesions are noncaseating granulomas in the affected organ or tissue. Indications, type of treatment, and duration of sarcoidosis treatment is currently debated. Despite studies showing that anti–tumor necrosis factor-α (TNF-α treatment can successfully be used in refractory sarcoidosis, there are some case reports regarding the development of sarcoidosis with these agents. There have been reports of 47 anti-TNF-associated cases of sarcoidosis until 2012. The patient is a 54-year-old Caucasian male. During routine examinations of the patient who had been followed for psoriasis vulgaris for 20 years and who had been on several anti-TNF regimens thereafter, new pulmonary pathologies due to sarcoidosis were detected. We present here a case of sarcoidosis that developed after infliximab treatment and showed obvious radiologic regression with discontinuation of treatment. During anti-TNF treatment, it should be kept in mind that autoimmune and granulomatous diseases may develop and particular care should be given to patient follow-ups.

    To report a case of choroidal sarcoid granuloma simulating choroidal metastasis in a patient with prostate carcinoma. Case report. A 66-year-old man was found to have an asymptomatic choroidal mass in his left eye. He had known history of pulmonary sarcoidosis without systemic involvement and prostate carcinoma without metastasis. On examination, visual acuity was 20/20 in each eye. Anterior segment was normal, without inflammatory sign in either eye. The right fundus was healthy. The left fundus revealed a yellow choroidal mass of 2 mm diameter, temporal to the foveola and without subretinal fluid, retinitis, or vitritis. Optical coherence tomography demonstrated a homogenous hyporeflective choroidal mass with intact retinal pigment epithelium and compression of choroidal vascular structures. Given the medical history and rarity of prostate metastasis to the uvea, choroidal sarcoid granuloma was considered and oral prednisone with a slow taper was given. After 2 months of therapy, tumor resolution with reduction in size was confirmed on optical coherence tomography. Choroidal sarcoid granuloma is a rare condition that can simulate choroidal metastasis. Treatment with prednisone can assist in establishing the diagnosis.

    The granuloma, a hallmark of host defense against pulmonary mycobacterial infection, has long been believed to be an active type 1 immune environment. However, the mechanisms regarding why granuloma fails to eliminate mycobacteria even in immune-competent hosts, have remained largely unclear. By using a model of pulmonary Mycobacterium bovis Bacillus Calmette-Guerin (BCG) infection, we have addressed this issue by comparing the immune responses within the airway luminal and granuloma compartments. We found that despite having a similar immune cellular profile to that in the airway lumen, the granuloma displayed severely suppressed type 1 immune cytokine but enhanced chemokine responses. Both antigen-presenting cells (APCs) and T cells in granuloma produced fewer type 1 immune molecules including tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), and nitric oxide. As a result, the granuloma APCs developed a reduced capacity to phagocytose mycobacteria and to induce T-cell proliferation. To examine the molecular mechanisms, we compared the levels of immune suppressive cytokine IL-10 in the airway lumen and granuloma and found that both granuloma APCs and T cells produced much more IL-10. Thus, IL-10 deficiency restored type 1 immune activation within the granuloma while having a minimal effect within the airway lumen. Hence, our study provides the first experimental evidence that, contrary to the conventional belief, the BCG-induced lung granuloma represents a symbiotic host-microbe microenvironment characterized by suppressed type 1 immune activation.

    2014-01-01

    Purpose of review None of the medications used in clinical practice to treat sarcoidosis have been approved by the regulatory authorities. Understanding how to use disease-modifying antisarcoid drugs, however, is essential for physicians treating patients with sarcoidosis. This review summarizes the recent studies of medications used for sarcoidosis with a focus on nonsteroidal therapies. Studies from 2006 to 2013 were considered for review to update clinicians on the most relevant literature published over the last few years. Recent findings Several recently published pieces of evidence have helped expand our ability to more appropriately sequence second-line and third-line therapies for sarcoidosis. For instance, methotrexate and azathioprine may be useful and well tolerated medications as second-line treatment. Mycophenolate mofetil might have a role in neurosarcoidosis. TNF-α blockers and other biologics seem to be well tolerated medications for the most severely affected patients. Summary Corticosteroids remain the first-line therapy for sarcoidosis as many patients never require treatment or only necessitate a short treatment duration. Second-line and third-line therapies described in this article should be used in patients with progressive or refractory disease or when life-threatening complications are evident at the time of presentation.

    2014-01-01

    Sarcoidosis is a chronic systemic disease of unknown etiology that is characterized by the presence of noncaseating epithelioid granulomas, usually in multiple organs. Several studies have shown that sarcoidosis might be the result of an exaggerated granulomatous reaction after exposure to unidentified antigens in genetically susceptible individuals. Cardiac involvement may occur and lead to an adverse outcome: the heart mechanics will be affected and that causes ventricular failure, and the cardiac electrical system will be disrupted and lead to third degree atrioventricular block, malignant ventricular tachycardia, and sudden cardiac death. Thus, early diagnosis and treatment of this potentially devastating disease is critically important. However, sensitive and accurate imaging modalities have not been established. Recent studies have demonstrated the promising potential of cardiac magnetic resonance imaging (MRI) and 18F-fluoro-2-deoxyglucose positron emission tomography (18F-FDG PET) in the diagnosis and assessment of cardiac sarcoidosis (CS). In this review, we discuss the epidemiology, etiology, histological findings, and clinical features of sarcoidosis. We also introduce advanced imaging including 18F-FDG PET and cardiac MRI as more reliable diagnostic modalities for CS. PMID:25250336

    Full Text Available Literature on concurrent association of sarcoidosis with lymphoproliferative malignancies other than lymphoma e.g. multiple myeloma is meager. The rarity of the situation prompted us to report this patient who was a 51-year-old woman with a 2-years history of breathlessness, cough with expectoration, chest pain and backache. Initial evaluation revealed mild anemia, increased alkaline phosphatase with chest skiagram showing both lower zone non homogenous opacities with calcified hilar lymph nodes. CECT chest showed mediastinal with bilateral hilar lymphadenopathy, parenchymal fibrosis, traction bronchiectasis, ground glass opacities, septal and peribronchovascular thickening affecting mid and lower lung zones bilaterally. MRI Dorsolumbar spine was suggestive of marrow infiltrative disorder. EBUS FNA of intrathoracic nodes, EBB and TBLB confirmed sarcoidosis. PET CT revealed hyper metabolic activity in lung, multiple lymph nodes and lytic bone lesions. Serum protein electrophoresis and immunofixation revealed a monoclonal paraprotein, immunoglobulin IgG kappa type. Bone marrow biopsy revealed an increase in plasma cells (15%, but no granulomas. Diagnosis of Indolent or multiple myeloma with sarcoidosis was established. 12 cases of sarcoidosis and multiple myeloma have been reported in literature, and mostly preceding the onset of multiple myeloma by many years, in our case both were diagnosed concurrently.

    Full Text Available Autoimmune endocrinopathies and, less commonly, thyroid autoimmune disease have been reported in patients with sarcoidosis. Similarities exist in the pathogenesis of these two conditions. Concomitant sarcoidosis in the thyroid gland in patients with Graves′ disease may contribute to the resistance to antithyroid drugs and radioiodine therapy. We present the clinical, laboratory, imaging, and pathologic findings of a patient with Graves′ disease who was unresponsive to medical management. This 37-year-old man presented with thyrotoxicosis. Thyroid hormone assays and 99m Technitium findings were consistent with Graves′ disease. He was also found to have hilar lymphadenopathy. Patient failed to achieve remission with high doses of antithyroid drugs and 2 sessions of radioiodine ablative therapy.Histopathology of lymph nodesdisclosed noncaseating granulomas, consistent with sarcoidosis. Patient′s thyrotoxicosis subsided only following steroid administration. The histopathology of the thyroid gland on aspiration and the subsidence of symptoms with steroids reiterate the possibility of thyroid sarcoidosis. This diagnosis needs biopsy for confirmation, which our patient didn′t consent for.

    Full Text Available Depending on the location, dermatoses can produce blemishes that severely impair quality of life and require highly effective treatment that is otherwise used for extensive skin involvement. We report the case of a 39-year-old, otherwise healthy male disfigured by an 8 × 7-cm hypopigmented and centrally atrophic annular plaque with erythematous indurated borders in an area of scar tissue on his forehead. Skin biopsies revealed non-caseating granulomas, and hilar involvement was identified, leading to the diagnosis of systemic sarcoidosis stage II with cutaneous involvement. The lesions proved resistant to multiple therapies, but responded within 4 months to adalimumab with regression of the lesion and inflammatory infiltrate. The visual analogue scale of disease activity decreased from 7/10 to 3.5/10, and the Dermatology Life Quality Index from 16/30 to 3/30 points. In conclusion, TNF-α inhibition can control inflammation and disfigurement by cutaneous sarcoidosis and restore quality of life.

    Sarcoidosis is a chronic, multisystemic, granulomatous disorder. Our patient was a 2-year-old girl with multiple airway conditions and a partial response to inhaled and systemic steroids. She was positive for acute phase reactants and negative for antibodies. Polymerase chain reaction revealed atypical Mycobacteria and she was negative for Mycobacterium tuberculosis. Laryngeal sarcoidosis was diagnosed by histopathology in a biopsy of larynx that revealed a chronic granulomatous inflammatory process with Langhans giant cells and acute and ulcerated areas with changes compatible with tuberculosis. Treatment consisted of monthly gammaglobulin for 6 months at doses of 2g/kg body weight, accompanied by Valmetrol™ and methotrexate. Immunomodulation with gammaglobulin was prescribed, with subsequent use of methotrexate-based immunosuppression. Currently, bronchoscopy shows no evidence of granulomas and she is negative for acute-phase reactants.

    Previous studies demonstrated that SAA staining of sarcoidosis granulomas was qualitatively and quantitatively different from other granulomatous diseases. These data suggest that positive SAA staining of granulomatous tissue may have adequate specificity to establish a diagnosis of sarcoidosis. Our objective was to determine the diagnostic specificity of SAA staining for sarcoidosis relative to other granulomatous disorders. Pathological specimens demonstrating granulomatous inflammation were retrospectively identified at one institution, plus 4 specimens were obtained from New York City firefighters with biopsy-confirmed World Trade Center "sarcoidosis-like" pulmonary disease. Specimens were analyzed if specific diagnoses related to the granulomatous inflammation were confirmed through medical record review. SAA staining was performed using previously developed methods. Two pathologists, blinded to each other and the diagnoses, determined if the stained material was SAA positive or negative. Discordant results were adjudicated by the two pathologists. 106 specimens were analyzed from 100 patients, with 36 biopsies (34%) from sarcoidosis tissues and 70 (66%) from other granulomatous disorders. The Cohen Kappa correlation between the two pathologists for SAA staining positivity was excellent (0.85, 0.73-0.98). The overall specificity of SAA staining for the diagnosis of sarcoidosis was 84% (59/70). The sensitivity was 44% (16/36). Although SAA staining of various granulomatous tissues was fairly specific for the diagnosis of sarcoidosis, the specificity was inadequate for SAA staining to be used as a diagnostic test for sarcoidosis in isolation. These data suggest that SAA production may not be a universal mechanism in the development of sarcoidosis. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Cutaneous sarcoidosis can present in pre-existing tattoos. Previous reports suggest modest improvement with systemic or topical corticosteroids or other immunomodulating medications. Tetracyclines have anti-inflammatory properties and have been shown to be efficacious in non-tattoo associated cutaneous sarcoidosis. The pharmacology of minocycline suggests that its higher concentration in the skin may improve its efficacy in the treatment of cutaneous granulomas. We present a case of a 35-year-old man with a history of pulmonary sarcoidosis who developed raised plaques within tattoos present for over 10 years. Skin biopsy findings revealed non-caseating granulomas consistent with cutaneous sarcoidosis. The patient was started on minocycline 100mg twice daily and had resolution of pruritus in four days and improvement of sarcoidal plaques within one week. To our knowledge, this is the first report of cutaneous sarcoidosis in tattoos treated with minocycline. Our patient's rapid response to minocycline suggests that minocycline may be a quickly effective medication for cutaneous sarcoidosis and should be considered as a therapeutic option given its favorable side-effect profile.

    We report a case of sarcoidosis that manifested as choroidal granuloma. We followed the treatment-associated changes in the granulomatous lesion by serial examinations using high-penetration optical coherence tomography (HP-OCT). A 77-year-old woman, who was referred to our clinic with granulomatous uveitis, presented initially with a yellowish-white subretinal granuloma formation surrounding the left optic disk. On presentation, diffuse keratic precipitates, anterior chamber inflammation and snowball-like vitreous opacity were observed. The HP-OCT image of subretinal lesion showed a low density choroidal space-occupying lesion. Due to the presence of bilateral hilar lymphadenopathy based on a close inspection of the entire body and abnormal cardiac/mediastinal uptake with positron emission tomography in combination with computed tomography (PET-CT), the definite clinical diagnosis group of sarcoidosis was made. Sub-Tenon injection of triamcinolone acetonide (STTA) was administered. In response to the treatment, HP-OCT showed that the choroidal granuloma had disappeared. Six months after treatment, the lesion recurred, however, this choroidal lesion resolved on OCT within the following 6 months in response to an STTA injection. As a complete atrioventricular block was observed during the follow-up, a pacemaker was implanted. The findings and clinical course strongly suggested choroidal granuloma of ocular sarcoidosis. HP-OCT allowed a detailed observation of the space-occupying lesion and helped make a diagnosis and observe the course of treatment.

    2017-03-01

    Sarcoidosis is a debilitating, inflammatory, multiorgan, granulomatous disease of unknown cause, commonly affecting the lung. In contrast to other chronic lung diseases such as interstitial pulmonary fibrosis or pulmonary arterial hypertension, there is so far no widely accepted or implemented animal model for this disease. This has hampered our insights into the etiology of sarcoidosis, the mechanisms of its pathogenesis, the identification of new biomarkers and diagnostic tools and, last not least, the development and implementation of novel treatment strategies. Over past years, however, a number of new animal models have been described that may provide useful tools to fill these critical knowledge gaps. In this review, we therefore outline the present status quo for animal models of sarcoidosis, comparing their pros and cons with respect to their ability to mimic the etiological, clinical and histological hallmarks of human disease and discuss their applicability for future research. Overall, the recent surge in animal models has markedly expanded our options for translational research; however, given the relative early stage of most animal models for sarcoidosis, appropriate replication of etiological and histological features of clinical disease, reproducibility and usefulness in terms of identification of new therapeutic targets and biomarkers, and testing of new treatments should be prioritized when considering the refinement of existing or the development of new models.

    Cryptococcus neoformans is an infrequent cause of septic arthritis. Cryptococcal infections have been linked to sarcoidosis because of both inherent immunologic consequences of the disease and its typical immune modulating treatments. Cryptococcal infections should be suspected in patients with underlying immune deficiencies, and a high degree of vigilance should be exercised to avoid misdiagnosis, dissemination of infection, and meningitis.

    To study treatment method of laryngeal nonspecific granuloma. Twenty-five patients with histopathologically identified laryngeal nonspecific granuloma were retrospective reviewed from 1998-2005. All patients were surgically treated by laser laryngomicrosurgery under general anesthesia, postoperative non-operative therapies included anti-gastroesophageal reflux medication, topical inhalant steroid (Beclometasone, Fluticasone) and voice therapy. Two patients were treated with 12 Gy of low-dose radiotherapy after surgery. Laryngeal nonspecific granuloma have remarkable tendency of recurrence despite of surgery and non-surgical managements. Recurrence of laryngeal nonspecific granuloma occurs between 2-3 months postoperatively and requires repeated operation for 3 5 times. For intubation granuloma, 6 out of 8 were healed. Six out of eight contact granulomas were healed. Six of gastroesophageal reflux granulomas were healed. Glottic carcinoma was demonstrated in one case after 2 sessions of combined managements. Two patients were completely healed by low-dose radiotherapy of 12 Gy. Laryngeal nonspecific granuloma have an obvious tendency of recurrence, however, surgery is an important therapy. Combined non-surgical therapies (anti-gastroesophageal reflux medication, topical inhalant steroid and voice therapy) are necessary. In case which routine ways fail to control recurrence, low-dose radiotherapy is recommended because of its safety and satisfied effect.

    Full Text Available Abstract Background Scar sarcoidosis is a rare and uncommon but specific cutaneous manifestation of sarcoidosis. In general it arises in pre-existing scars deriving from mechanical traumas. As most surgeons dealing with scars might not be aware of cutaneous sarcoidosis and its different types of appearance the appropriate staging and treatment might be missed or at least delayed. To our knowledge this is the first case in literature of scar sarcoidosis on a finger. Case presentation We present a case of a 33-year-old carpenter who developed scar sarcoidosis on his right index finger 4 years after the tendon of the long digital flexor got accidentally cut by an angle grinder. He was referred due to a swelling of the finger suspected to be a malignant soft tissue tumour. The circumference of the affected finger had almost doubled, adding up to 94 mm. Incision biopsy revealed typical noncaseating granulomas. Further investigation showed a systemic extent of the disease with involvement of the lung. A systemic treatment with oral steroids led to an almost full regression of the swelling with restoration of function and resolution of lung infiltrates. Conclusion In case of a suspicious and/or progressive swelling a definite diagnosis should be achieved by biopsy within a short time to enable a proper treatment. If scar sarcoidosis is proven further investigation is necessary to exclude a systemical involvement. A surgical treatment of the swelling is not indicated.

    Substance P (SP) is a proinflammatory neuropeptide that is secreted by sensory nerves and inflammatory cells. Increased levels of SP are found in sarcoid bronchoalveolar lavage fluid. SP acts by binding to the neurokinin-1 receptor and increases secretion of tumor necrosis factor-alpha in many cell types. We sought to determine neurokinin-1 receptor expression in patients with sarcoidosis compared with normal controls. Neurokinin-1 receptor messenger RNA and protein expression were below the limits of detection by reverse transcriptase-polymerase chain reaction and immunohistochemistry in peripheral blood mononuclear cells of healthy volunteers (n = 9) or patients with stage 1 or 2 pulmonary sarcoidosis (n = 10), but were detected in 1\\/9 bronchoalveolar lavage cells of controls compared with 8\\/10 patients with sarcoidosis (p = 0.012) and 2\\/9 biopsies of controls compared with 9\\/10 patients with sarcoidosis (p = 0.013). Immunohistochemistry localized upregulated neurokinin-1 receptor expression to bronchial and alveolar epithelial cells, macrophages, lymphocytes, and sarcoid granulomas. The patient in whom neurokinin-1 receptor was not detected was taking corticosteroids. Incubation of the type II alveolar and bronchial epithelial cell lines A549 and SK-LU 1 with dexamethasone downregulated neurokinin-1 receptor expression. Upregulated neurokinin-1 receptor expression in patients with sarcoidosis may potentiate substance P-induced proinflammatory cytokine production in patients with sarcoidosis.

  10. Imbalance between Th17 and Regulatory T-Cells in Sarcoidosis

    Full Text Available Sarcoidosis is a systemic granulomatous disease, which is thought to result from an aberrant immune response. CD4+ T lymphocytes play an important role in the development of granulomas. Previously, the immunopathogenesis of sarcoidosis was focused on Th1/Th2 disturbances. The aim of this study was to evaluate the balance between newer CD4+ T lymphocytes, i.e., Treg and Th17 cells. In our studies, a decrease in Treg cells and an increase in Th17 cells were observed in the peripheral blood and BALF of sarcoidosis patients. A significant increase in the Th17/Treg cell ratio was observed in sarcoidosis patients. After treatment with prednisone, the expression of Foxp3 mRNA was elevated in the peripheral blood, and expression of (RORγt mRNA showed a downward trend. These findings suggest that sarcoidosis is associated with an imbalance between Th17 and Treg cells in peripheral blood and BALF. Therefore, targeting the cytokines that affect the Th17/Treg ratio could provide a new promising therapy for pulmonary sarcoidosis.

    Sarcoidosis is a multisystemic disorder of unknown etiology, characterised by the presence of non-caseating granulomas in target organs. In ninety percent of cases, there is thoracic involvement. Fifty to seventy percent of pulmonary sarcoidosis patients will experience acute, self-limiting disease. For the subgroup of patients who develop persistent disease, no targeted therapy is currently available. To investigate the potential of the single nucleotide polymorphism (SNP), Toll-like receptor 3 Leu412Phe (TLR3 L412F; rs3775291), as a causative factor in the development of, and in disease persistence in pulmonary sarcoidosis. To investigate the functionality of TLR3 L412F in vitro in primary human lung fibroblasts from pulmonary sarcoidosis patients. Cohorts of Irish sarcoidosis patients (n = 228), healthy Irish controls (n = 263) and a secondary cohort of American sarcoidosis patients (n = 123) were genotyped for TLR3 L412F. Additionally, the effect of TLR3 L412F in primary lung fibroblasts from pulmonary sarcoidosis patients was quantitated following TLR3 activation in the context of cytokine and type I interferon production, TLR3 expression, and apoptotic- and fibroproliferative-responses. We report a significant association between TLR3 L412F and persistent clinical disease in two cohorts of Irish and American Caucasians with pulmonary sarcoidosis. Furthermore, activation of TLR3 in primary lung fibroblasts from 412F-homozygous pulmonary sarcoidosis patients resulted in reduced IFN-β and TLR3 expression, reduced apoptosis- and dysregulated fibroproliferative-responses compared with TLR3 wild-type patients. This study identifies defective TLR3 function as a previously unidentified factor in persistent clinical disease in pulmonary sarcoidosis and reveals TLR3 L412F as a candidate biomarker.

  13. Genotyping in the MHC locus: potential for defining predictive markers in sarcoidosis

    Full Text Available Abstract In sarcoidosis, host genetic factors are discussed as contributing to disease susceptibility and course. Since tumor necrosis factor (TNF-α is a central mediator of granuloma formation and since elevated TNF-α levels are found during active phases of sarcoidosis, genetic polymorphisms correlating with influences on TNF-α levels are of special interest. The complete sequencing of the MHC region and the increase in the number of identified gene polymorphisms in this locus associated with TNF-α production offer the opportunity of detecting new genes associated with sarcoidosis and perhaps of defining disease-associated haplotypes that bear the potential of serving as predictive markers for this disease.

    Granuloma faciale (GF) is a rare benign inflammatory dermatosis that usually develops as a solitary brownish-red plaque on the face. It clinically mimics and is often misinterpreted as, sarcoidosis, lupus erythematosus, lupus vulgaris, lymphoma or basal cell carcinoma.Dermoscopy, which is valuable for evaluation and differentiation between malignant and benign skin tumors, allows better visualization of dermal vascular structures and color variations. In this context, it might serve as an adjuvant diagnostic tool in the differentiation of inflammatory disorders, too. In the current manuscript, we present the dermoscopic features observed in a lesion of GF and discuss them in correlation with the underlying histopathological alterations.

    Full Text Available Sarcoidosis is a systemic inflammatory disease characterised by appearance of granulomas. Precise etiology has not been elucidated. Osteopontin (Opn is a Th1 cytokine whose levels have been found increased in granulomas and serum samples from patients with sarcoidosis. We investigated whether genetic variation in Osteopontin gene (OPN gene contributes to susceptibility to sarcoidosis. Haplotype-block structure in the OPN gene region was investigated using data from HapMap project. Three representative SNPs have been selected from each block of SNPs in linkage disequilibrium (rs11730582-C/T, rs11728697-C/T and rs4754-C/T. Genotyping was performed using TaqMan SNP Genotyping Assays on a sample of 165 patients and 284 controls. Statistical analyses of association were performed using Chi-Square test and algorithms implemented in the haplo.stats and PHASE packages. Genotyping analysis revealed a significant difference in genotype frequencies at rs4754 polymorphism in groups of patients and controls under recessive genetic model (p=0.036, OR=1.99, 95%CI=1.04-3.82, CC homozygotes being significantly over-represented in the patients group. However these results failed to reach significance after correction for multiple testing (p=0.25. The frequencies of predicted haplotypes differed between patient and control groups, frequency of TTT haplotype was found to be significantly decreased in the group of patients with sarcoidosis (p=0.014, OR=0.40, 95%CI=0.20-0.79. Our results suggest that variation in the OPN gene might be significantly associated with sarcoidosis and that the TTT haplotype in OPN may act as a protective factor in sarcoidosis.

    Pulmonary sarcoidosis (PS) is characterized by the formation of granulomas in the lungs and has been associated with infection by microorganisms. Triggering receptor expressed on the surface of myeloid cells (TREM)-1 is overexpressed in response to infection while TREM-2 is involved in granuloma formation. We hypothesized that these receptors are overexpressed in PS and might be useful for diagnostic testing. Cell surface TREM-1 and TREM-2 expression in cells obtained at bronchoalveolar lavage (BAL) was measured in individuals with sarcoidosis (n = 26) and compared with that seen in individuals with other interstitial lung diseases (ILD) (n = 27). TREM-1 and TREM-2 expression was significantly increased in sarcoidosis compared with other ILD: total number of TREM-1, P = 0.0039 (23.81 vs 13.50 cells/μl), TREM-2, P < 0.0001 (32.81 vs 7.76 cells/μl); percentage of TREM-1: P = 0.0002 (41.30% vs 15.70%), TREM-2: P < 0.0001 (34% vs 9.60%); and mean fluorescence of TREM-1: P = 0.0005 (5.43 vs 1.96), TREM-2: P = 0.0011 (6.85 vs 2.77). Increase in both of these receptors seems to be typical for PS. In discriminating sarcoidosis from other ILD, the specificity (96%) and sensitivity (72%) of the combination of TREM-1 and TREM-2 was high. Increased TREM-1 and TREM-2 cell surface expression is observed in sarcoidosis. Evaluation of BAL cell expression of both of these receptors may serve as a diagnostic marker for sarcoidosis. © 2013 The Authors. Respirology © 2013 Asian Pacific Society of Respirology.

    To report outcomes of treatment for laryngeal contact granuloma. Prospective treatment of 21 patients with laryngeal contact granulomas using proton-pump inhibitor (PPI) medication. Patients were diagnosed and followed by office endoscopy and patient interview. Three patients did not tolerate PPI medication and were managed by treatment with type 2 histamine (H2) blockers. The lesion completely resolved in 14 of the 18 patients maintained on PPI medication, and significantly regressed in the other 4. Residual granulomas were surgically excised in one patient. Lesions resolved in two patients following injection of botulinum toxin into one thyroarytenoid muscle. One patient had a residual lesion, but symptoms were controlled by medication, and he declined treatment with botulinum toxin. Of the three patients treated with H2-blocker medication, the lesion resolved in only one. PPI medication is effective in the treatment of laryngeal contact granuloma, even in the absence of identifiable symptoms of gastroesophageal reflux.

    Purpose of Review Chronic sarcoidosis is a complex disease with numerous comorbid conditions and can be fatal in some cases. Recognizing causes of morbidity and mortality is important to effectively select treatments, manage symptoms, and improve outcomes. The purpose of this review is to examine emerging knowledge on morbidity and mortality in sarcoidosis. Recent Findings Approximately one to five percent of patients with sarcoidosis die from complications of sarcoidosis. Recent population studies indicate that mortality may be increasing over the past decade. The reasons behind these trends are unclear, but could include increasing incidence, detection rates, severity of disease, or age of the population. Morbidity of sarcoidosis is reflected by a trend of increased hospitalizations over recent years and increased use of healthcare resources. Morbidity can be caused by organ damage from granulomatous inflammation, treatment complications, and psychosocial effects of the disease. Recent studies are focused on morbidity related to cardiopulmonary complications, bone health, and aging within the sarcoidosis population. Last, sarcoidosis is associated with autoimmune diseases, pulmonary embolism, and malignancy; however, the underlying mechanisms linking diseases continue to be debated. Summary Morbidity in sarcoidosis is significant and multifactorial. Mortality is infrequent, but may be increasing over the years. PMID:25029298

    Sarcoidosis is a well-recognized systemic granulomatous process which involves the central nervous system in 5-15% of patients. One of the more frequent sites of central nervous system involvement is the pituitary and hypothalamic region. Involvement of the sellar region by sarcoidosis is overall an infrequent occurrence, comprising less than 1% of all intrasellar lesions. Patients typically present with an infiltrative lesion on imaging studies and clinically with symptoms related to diabetes insipidus or hyperprolactinemia. This report describes a 38-year-old woman who initially presented with a variety of symptoms including headaches, light sensitivity, nausea and vomiting, acute visual changes, cold intolerance, amenorrhea, decreased libido, fatigue and galactorrhea. She had an elevated serum prolactin level and evidence of oligoclonal bands in the cerebrospinal fluid. Imaging studies discovered a 1.8cm mass involving the pituitary gland and compressing the optic chiasm. The lesion was excised and microscopically was marked by a chronic inflammatory cell infiltrate and scattered nonnecrotizing granulomas. Stains and microbiologic cultures failed to demonstrate microorganisms. There was no evidence of other organ involvement on postoperative imaging. She was treated with prednisone with improvement of symptoms and subsequently required methotrexate to treat left eye pain and blurred vision, 29months after her surgery. Achieving treatment control in patients with pituitary and hypothalamic improvement in sarcoidosis still remains a challenge. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Introduction Although the causes of sarcoidosis are still unknown, past and current studies have provided evidence that this disease may be associated with occupational exposure to specific environmental agents. We describe a case of sarcoidosis in a dental surgeon with long exposure to inorganic dusts. To the best of our knowledge, this is the first report of this kind in the literature. Case presentation At the beginning of 2000, a 52-year-old Caucasian man, who worked as a dental surgeon, presented with shortness of breath during exercise, cough and retrosternal pain. After diagnosis of sarcoidosis, a scanning electronic microscopy with X-ray microanalysis of biopsy specimens was used in order to determine whether the disease could be traced to an occupational environmental agent. Results showed the presence of inorganic dust particles within sarcoidotic granulomas, and demonstrated that the material detected was identical to that found in a powder used by our patient for several years. Conclusions Although these results cannot be considered as definitive proof, they do however provide strong evidence that this disease may be associated with material used by dental surgeons.

  3. Evidence for Mycobacteria in Sarcoidosis

    Despite its recognition as a distinct granulomatous disease for over a century, the etiology of sarcoidosis remains to be defined. Since the early 1900s, infectious agents have been suspected in causing sarcoidosis. For much of this time, mycobacteria were considered a likely culprit, yet until recently, the supporting evidence has been tenuous at best. In this review, we evaluate the reported association between mycobacteria and sarcoidosis. Historically, mycobacterial infection has been investigated using histologic stains, cultures of lesional tissue or blood, and identification of bacterial nucleic acids or bacterial antigens. More recently, advances in biochemical, molecular, and immunological methods have produced a more rigorous analysis of the antigenic drivers of sarcoidosis. The result of these efforts indicates that mycobacterial products likely play a role in at least a subset of sarcoidosis cases. This information, coupled with a better understanding of genetic susceptibility to this complex disease, has therapeutic implications. PMID:21659662

    Sarcoidosis is a systemic granulomatous inflammation of unknown etiology, and seems to involve the liver parenchyma in most cases. However, sarcoidosis-associated hepatocellular carcinoma is rare. We report here a case in which a hepatocellular carcinoma occurred within the liver, which was probably involved as a result of systemic sarcoidosis. A 57-year-old Japanese man had been followed up for 2 years because of diabetic nephropathy and sarcoidosis. On admission for pneumonia, imaging studies revealed an unexpected hepatic tumor. Histology revealed a hepatocellular carcinoma accompanied by T-lymphocytic infiltration and marked granulomatous inflammation, which was surrounding some tumor nodules. The background liver parenchyma exhibited a moderate degree of fibrosis with granulomatous inflammation. The patient had no other apparent liver disease such as viral hepatitis, steatohepatitis, or primary biliary cirrhosis. Therefore, in the present case, sarcoidosis may be considered the probable background etiology for hepatocarcinogenesis.

    Yoshinobu Eishi

    2013-01-01

    Full Text Available Sarcoidosis is a systemic granulomatous disease of unknown etiology. Propionibacterium acnes is the only microorganism that has been isolated from sarcoid lesions. Many P. acnes have been detected in sarcoid lymph nodes using quantitative PCR and in sarcoid granulomas by in situ hybridization. P. acnes trigger factor protein causes a cellular immune response only in sarcoid patients and induces pulmonary granulomas in mice sensitized with the protein and adjuvant, but only those with latent P. acnes infection in their lungs. Eradication of P. acnes by antibiotics prevents the development of granulomas in this experimental model. Although P. acnes is the most common commensal bacterium in the lungs and lymph nodes, P. acnes-specific antibody detected the bacterium within sarcoid granulomas of these organs. P. acnes can cause latent infection in the lung and lymph node and persist in a cell-wall-deficient form. The dormant form is activated endogenously under certain conditions and proliferates at the site of latent infection. In patients with P. acnes hypersensitivity, granulomatous inflammation is triggered by intracellular proliferation of the bacterium. Proliferating bacteria may escape granulomatous isolation, spreading to other organs. Latent P. acnes infection in systemic organs can be reactivated by another triggering event, leading to systemic sarcoidosis.

    Full Text Available Objective To improve the ability of clinicians in the recognition, diagnosis and treatment of sarcoidosis with renal damage through analyzing the clinical data of one case of sarcoidosis with renal damage and literature review. Methods One case of sarcoidosis with renal damage was reported. The case history, clinical manifestations, pathological features, diagnosis and treatment of the patient were analyzed, and the related literature published domestically and abroad was reviewed to summarize the experiences in diagnosis and treatment of the disease. Results The patient was a 39 years old woman. The primary main clinical manifestations were cough and fever. Renal damage manifesting proteinuria and microscopic hematuria appeared one month later, and chest CT showed mediastinum and bilateral hilar lymphadenectasis. Renal and tracheal mucosa biopsy revealed noncaseating necrotized granuloma, so the diagnosis of sarcoidosis with renal damage was confirmed. Administration of glucocorticoid combined with cyclophosphamide achieved good therapeutic effect: hypercalciuria and proteinuria that lymph nodes in were abated with urinary calcium and protein returned to normal level, and microscopic hematuria disappeared. Chest CT showed mediastinum and hilum on both sides reduced significantly in size compared with those before the treatment. Conclusion  Sarcoidosis with renal damage is a rare disease with atypical clinical manifestations. Early diagnosis and timely treatment may achieve good effects.

The clinical expression was uniform with pale, smooth swellings of the supraglottic structures. Surgery proved...... successful to maintain normal breathing. None of the many parameters examined--some previously having been found to be abnormal in sarcoidosis--were abnormal in the present cohort. We are therefore unable to elucidate the pathogenesis.

    Full Text Available In this study, we sought to identify differentially expressed proteins in the serum of patients with sarcoidosis or tuberculosis and to evaluate these proteins as markers for the differential diagnosis of sarcoidosis and sputum-negative tuberculosis.Using protein microarrays, we identified 3 proteins exhibiting differential expression between patients with sarcoidosis and tuberculosis. Elevated expression of these proteins was verified using the enzyme-linked immunosorbent assay (ELISA and was further confirmed by immunohistochemistry. Receiver operating characteristic (ROC curve, logistic regression analysis, parallel, and serial tests were used to evaluate the diagnostic efficacy of the proteins.Intercellular Adhesion Molecule 1(ICAM-1 and leptin were screened for differentially expressed proteins relevant to sarcoidosis and tuberculosis. Using ROC curves, we found that ICAM-1 (cutoff value: 57740 pg/mL had an area under the curve (AUC, sensitivity, and specificity of 0.718, 62.3%, and 79.5% respectively, while leptin (cutoff value: 1193.186 pg/mL had an AUC, sensitivity, and specificity of 0.763, 88.3%, and 65.8%, respectively. Logistic regression analysis revealed that the AUC, sensitivity, and specificity of combined leptin and ICAM-1 were 0.787, 89.6%, and 65.8%, respectively, while those of combined leptin, ICAM-1, and body mass index (BMI were 0.837, 90.9%, and 64.4%, respectively, which had the greatest diagnostic value. Parallel and serial tests indicated that the BMI-leptin parallel with the ICAM-1 serial was the best diagnostic method, achieving a sensitivity and specificity of 86.5% and 73.1%, respectively. Thus, our results identified elevated expression of ICAM-1 and leptin in serum and granulomas of sarcoidosis patients.ICAM-1 and leptin were found to be potential markers for the diagnosis of sarcoidosis and differential diagnosis of sarcoidosis and sputum-negative tuberculosis.

    Cryptococcal intraocular infection is a rare disease and is usually associated with generalized systemic disease in immunocompromised patients. The diagnosis may be difficult because of the rarity of this disease and its similarities to other uveitic entities. We describe a case of culture-positive cryptococcal iridociliary granuloma diagnosed by anterior chamber tap and fine-needle aspiration biopsy in a 60-year-old immunocompetent woman with acute granulomatous uveitis. She was treated successfully with systemic amphotericin B and fluconazole and intravitreal amphotericin B, with improvement in the inflammation and visual acuity and regression of the iridociliary granuloma. We review previously reported cases of intraocular cryptococcal infection. Cryptococcal iridociliary granuloma should be considered in the differential diagnosis of an atypical iridociliary mass associated with acute uveitis. Copyright © 2015 Elsevier Inc.

    Full Text Available Plasma cell granuloma, also known as inflammatory pseudotumor is a tumor-like lesion that manifests primarily in the lungs. But it may occur in various other anatomic locations like orbit, head and neck, liver and rarely in the oral cavity. We here report an exceedingly rare case of gingival plasma cell granuloma in a 58 year old woman who presented with upper gingival polypoidal growth. The histopathological examination revealed a mass composed of proliferation of benign spindle mesenchymal cells in a loose myxoid and fibrocollagenous stroma along with dense infiltrate of chronic inflammatory cells predominantly containing plasma cells. Immunohistochemistry for kappa and lambda light chains showed a polyclonal staining pattern confirming a diagnosis of plasma cell granuloma.

    Full Text Available A case of mycotic bovine nasal granuloma in a 10 year-old Jersey cow, produced by Drechslera halodes is presented. Histopathological sections showed abundant hyaline and pigmented extra and intracellular fungal structures together with a polymorphic cellular granuloma formed by neutrophils, lymphocytes, plasmocytes, histiocytes and giant cells of the Langhans type. It is the first case of mycotic bovine nasal granuloma recognized in Uruguay although this disease seems to be frequent according to the opinion of veterinarian specialists. Another similar clinical case also in a Jersey cow from the same dairy house with an intense cellular infiltrate rich in eosinophils without granulomatous image, together with extracellular hyaline and fuliginous fungal forms, is also referred for comparative purposes. Geotrichum sp. was isolated. The need of an early diagnosis and treatment of the disease is stressed.

    Sarcoidosis is a juvenile systemic granulomatosis. Its polymorphic clinical presentation depends on its different localisations, thoracic and extrathoracic. The role of imaging is very important for all localisations; but for mediastinopulmonary involvement, which is the most frequent (>90% of cases), it plays a major role in detecting the disease, diagnosing it, its prognosis, decision-making regarding treatment of it and in the monitoring of its development. Standard radiography, which sometimes detects the disease, forms the basis for its four-stage prognostic classification. CT scanning enables the study of mediastinal and hilar lymphadenopathy and the study of parenchyma, making it possible to identify micronodules of lymphatic distributions, alveolar opacities, septal lines, ground-glass hyperintensities, nodules surrounded by a ring of satellite micronodules, peribronchovascular thickening; all potentially reversible lesions. Elsewhere, it highlights irreversible fibrous lesions: hilar peripheral linear opacities; septal linear opacities; bronchial distortion, honeycomb destruction or even perihilar fibrotic masses. Less frequently we can visualise bronchiolar or cystic involvement. Benign in most cases, the sarcoidosis prognosis becomes bleaker in the event of hemoptysis, Aspergillus colonisation or before the onset of pulmonary hypertension.

    Kveim-reagent (Kv) skin testing was a historical method of diagnosing sarcoidosis. Intradermal injection of treated sarcoidosis spleen tissue resulted in a granuloma response at injection site by 4-6 weeks. Previous work indicates proteins as the possible trigger of this reaction. We aimed to identify Kv-specific proteins and characterise the ex vivo response of Peripheral Blood Mononuclear Cells (PBMCs) from sarcoidosis, tuberculosis and healthy control patients when stimulated with both Kv and selected Kv-specific proteins. Kv extracts were separated by 1D-SDS-PAGE and 2D-DIGE and then underwent mass spectrometric analysis for protein identification. Sarcoidosis and control PBMCs were first stimulated with Kv and then with three selected recombinant protein candidates which were identified from the proteomic analysis. PBMC secreted cytokines were subsequently measured by Multiplex Cytokine Assay. We observed significantly increased IFN-γ and TNF-α secretion from Kv-stimulated PBMCs of sarcoidosis patients vs. PBMCs from healthy volunteers (IFN-γ: 207.2 pg/mL vs. 3.86 pg/mL, p = 0.0018; TNF-α: 2375 pg/mL vs. 42.82 pg/mL, p = 0.0003). Through proteomic approaches we then identified 74 sarcoidosis tissue-specific proteins. Of these, 3 proteins (vimentin, tubulin and alpha-actinin-4) were identified using both 1D-SDS-PAGE and 2D-DIGE. Data are available via ProteomeXchange with identifier PXD005150. Increased cytokine secretion was subsequently observed with vimentin stimulation of sarcoidosis PBMCs vs. tuberculosis PBMCs (IFN-γ: 396.6 pg/mL vs 0.1 pg/mL, p = 0.0009; TNF-α: 1139 pg/mL vs 0.1 pg/mL, psarcoidosis PBMCs compared to PBMCs from healthy controls (IFN-γ: 396.6 pg/mL vs. 0.1 pg/mL, p = 0.014; TNF-α: 1139 pg/mL vs 42.29 pg/mL, p = 0.027). No difference was found in cytokine secretion between sarcoidosis and control PBMCs when stimulated with either tubulin or alpha-actinin-4. Stimulation with both Kveim reagent and vimentin induces a specific pro

    Sarcoidosis is characterized by the appearance of noncausating, epitheloid cell granulomas, primarily in skin and lung. Hereditary disposition is well known; additional infection-associated triggers play a role for the development of inflammation mediated by T helper (Th)1 cells. Clinically, various disease courses can be observed that are characterized by the formation of skin papules at typical sites of the body which differ in their tendency to be associated with systemic organ involvement. Systemic disease without skin affections is also possible. The diagnosis is based on the typical clinical appearance, biopsy of affected tissue (e.g. skin, lung) and laboratory investigations. Additional systemic involvement needs to be excluded. In most cases, the disease is self-limited, but can also be life threatening due to organ fibrosis. The degree of (extra-)cutaneous involvement and level of discomfort are used to select the type of treatment, which ranges from topical immune suppressive agents to systemic therapy with corticosteroids. In nonresponders, additional modern immunosuppressive/immunomodulating therapeutic options are available.

    Full Text Available Abstract Background Sarcoidosis is an inflammatory disorder of immune dysregulation characterized by non-caseating granulomas that can affect any organ. Cardiac sarcoidosis is an under-recognized entity that has a heterogeneous presentation and may occur independently or with any severity of systemic disease. Diagnosing cardiac sarcoidosis remains problematic with endomyocardial biopsies associated with a high risk of complications. Several diagnostic algorithms are currently available that rely on histopathology or clinical and radiological measures. The dominant mode of diagnostic imaging to date for cardiac sarcoidosis has been cardiac magnetic resonance imaging with gadolinium enhancement. Case presentations We report the cases of two adult patients: case 1, a 50-year-old white man who presented with severe congestive cardiac failure; and case 2, a 37-year-old white woman who presented with complete heart block. Both patients had a background of untreated pulmonary sarcoidosis. Cardiac magnetic resonance imaging did not show evidence of sarcoidosis in either patient and both proceeded to 18F-fluorodeoxyglucose-positron emission tomography scans that were highly suggestive of cardiac sarcoidosis. Both patients were systemically immunosuppressed with orally administered prednisone and methotrexate and had subsequent improvement by clinical and nuclear medicine imaging measures. Conclusions Current consensus guidelines recommend all patients with sarcoidosis undergo screening for occult cardiac disease, with thorough history and examination, electrocardiogram, and transthoracic echocardiogram. If any abnormalities are detected, advanced cardiac imaging should follow. While cardiac magnetic resonance imaging identifies the majority of cardiac sarcoidosis, early disease may not be detected. These cases demonstrate 18F-fluorodeoxyglucose-positron emission tomography is warranted following an indeterminate or normal cardiac magnetic resonance

    Full Text Available Most of the studies have shown a higher risk for subclinical and clinical hypothyroidism, antithyroid autoantibodies [overall antithyroid peroxidase antibodies (TPOAb], and in general, thyroid autoimmunity, overall in the female gender in patients with sarcoidosis (S. A significantly higher prevalence of clinical hypothyroidism and Graves’ disease was also described in female S patients with respect to controls. Gallium-67 (Ga-67 scyntigraphy in S patients, in the case of thyroid uptake, suggests the presence of aggressive autoimmune thyroiditis and hypothyroidism. For this reason, ultrasonography and thyroid function should be done in the case of Ga-67 thyroid uptake. In conclusion, thyroid function, TPOAb measurement, and ultrasonography should be done to assess the clinical profile in female S patients, and the ones at high risk (female individuals, with TPOAb positivity, and hypoechoic and small thyroid should have periodically thyroid function evaluations and suitable treatments.

    Sarcoidosis is a systemic disease characterized by an immune-mediated disorder, which leads to the development of non-caseating granulomas in the involved organs. More than 90% of patients with sarcoidosis present lungs and lymphatic system involvement at onset, while less than 10% has an isolated extrapulmonary localization. Here, we describe the case of an elderly patient with isolated hepato-splenic onset (multiple splenic lesions at imaging and cholestasis), and subsequent pulmonary involvement. The liver biopsy showed the presence of non-caseating granulomas, suggesting sarcoidosis. Despite the complete recovery was obtained with steroid therapy, after dosage reduction the patient presented watery diarrhea. Endoscopic investigations with biopsies were performed, describing the presence of an important lympho-plasmacytic infiltrate of terminal ileum mucosa with typical aspects of inflammatory bowel disease. The symptomatology completely disappeared after steroid dosage increase. This case confirms that sarcoidosis could present in a very atypical way, involving several organs in a different manner at the same time and that every symptom should not be underestimated, despite the rare presentation.

    Sarcoidosis is a systemic autoimmune disease where an inflammatory reaction involving alveolar macrophages, T-helper lymphocytes, and epitheloid cells is mounted against unknown antigens. A genetic predisposition for sarcoidosis is supposed by studies in twins, by geographical and racial distribution. In the current investigation we compared the expression patterns between slow onset and acute sarcodosis using a whole-genome cDNA array. Bronchoalveolar lavage was performed in six patients with slow onset sarcoidosis and four patients with acute sarcoidosis (Löfgren's disease) and obtained cells were used for gene expression profiling. The results were confirmed by RT- and Taqman-PCR. In addition, protein expression was examined on paraffin sections of sarcoid granulomas by immunohistochemistry. In T-helper lymphocytes and alveolar macrophages we found an upregulation of genes belonging to the phosphoinositol-3-kinase/v-akt murine thymoma viral oncogene homolog/signal transducer and activator of transcription 3 pathway, as well as a downregulation of genes of the extrinsic and intrinsic apoptotic signaling cascades. In addition an upregulation of the genes encoding fatty acid binding protein 4 and 5, as well as peroxisome proliferative activated receptor delta in Löfgren's disease was detected. Differences in gene expression between slow onset sarcoidosis and Löfgren's syndrome were found mainly within genes of the major histocompatibility complex. In sarcoidosis enhanced cell proliferation and decreased apoptosis result in accumulation and prolonged survival of antigen-primed T-helper lymphocytes and activated macrophages. This is enhanced in Löfgren's disease, probably by hyper-stimulation via the peroxisome proliferation signaling, providing a larger pool of antigen-primed immune cells.

    Introduction. Sarcoidosis is a multisystemic granulomatous disorder characterized by multiple noncaseating granulomas involving intrathoracic lymph nodes and lung parenchyma. Recently, the use of anti-tumor necrosis factor alpha (anti-TNFα) agents has been introduced for therapy of chronic and refractory sarcoidosis with controversial results. Infliximab (Remicade) is a chimeric monoclonal antibody (mAb) that recognizes and binds TNFα, neutralizing its biological effects. In the present study,   99mTc labelled infliximab was used to study the expression of TNFα in sarcoid lesions and to evaluate its role as a predictive marker in response to therapy with Remicade. Material and Methods. A total of 10 patients with newly diagnosed sarcoidosis were enrolled together with 10 control patients affected by rheumatoid arthritis. All patients were studied by planar imaging of the chest with   99mTc-infliximab at 6 h and 24 h and total body [18F]-FDG PET/CT. Regions of interest were drawn over the lungs and the right arm and target-to-background ratios were analysed for   99mTc-infliximab. SUVmean and SUVmax were calculated over lungs for FDG. Results and Discussion. Image analysis showed low correlation between T/B ratios and BAL results in patients despite positivity at [18F]-FDG PET. Conclusion. In conclusion, patients with newly diagnosed pulmonary sarcoidosis, with FDG-PET and BAL positivity, showed a negative   99mTc-infliximab scintigraphy. PMID:25866780

    Full Text Available Purpose: To report an undiagnosed case of systemic sarcoidosis manifesting with bilateral acute posterior multifocal placoid pigment epitheliopathy (APMPPE. Case Report: A 26-year-old Caucasian man was referred for management of unilateral visual loss together with a paracentral scotoma developing 2 weeks after a flu-like syndrome. Clinical signs and ancillary diagnostic investigations suggested APMPPE. Laboratory tests demonstrated elevated serum angiotensin converting enzyme and lysozyme levels. Chest CT-scan disclosed moderate hilar lymph node calcifications but QuantiFERON-TB gold test was negative and bronchoalveolar lavage and biopsies were unremarkable. Accessory salivary gland biopsy disclosed epithelioid and gigantocellular granuloma formation without caseum, confirming a diagnosis of sarcoidosis. The fellow eye was involved a few days later and the patient complained of dyspnea. Echocardiography disclosed severe granulomatous myocardial infiltration and high dose corticosteroids and intravenous cyclophosphamide were initiated. Systemic treatment controlled both cardiac and ocular lesions, and was tapered accordingly. Conclusion: The constellation of "white dot syndromes" and systemic symptoms necessitates a general work-up to exclude granulomatous disorders such as sarcoidosis or tuberculosis. Delayed diagnosis of cardiac sarcoidosis may have life-threatening consequences and the ophthalmologist may be the first physician to diagnose the condition.

    Gastric sarcoidosis with noncaseating granuloma is rare. Although corticosteroid produces a dramatic clinical response, it is unknown whether azathioprine show efficacy in prednisolone-dependent cases. Here, we report a case of gastric sarcoidosis in a 25-year-old man with severe epigastlargia. Gastroendoscopy revealed multiple map-like ulcerations. Histological examination showed multiple noncaseating granulomatous lesions in gastric mucosa, which were incompatible with diagnoses of Crohn's disease or tuberculosis. He was started on prednisolone at 30 mg/d, and his symptoms improved within 7-d. The prednisolone was gradually tapered by 5 mg every 2-wk, but oral azathioprine at 50 mg was added after symptoms recurred at tapered dose of 10 mg. Endoscopy 4-wk later showed healing ulcers, and, lymphocytic infiltration was absent. The efficacy of additional azathioprine in gastric sarcoidosis is not well defined. Here, we report a case of prednisolone-dependent gastric sarcoidosis that improved after additional azathioprine, and also review the literature concerning the treatment, especially for prednisolone-dependent cases.

    Full Text Available Sarcoidosis is an idiopathic, systemic disease that rarely involves the genitourinary tract. Here, we present a case of a 40-year-old male presented with bilateral scrotal swelling. The scrotal ultrasound showed multiple echogenic masses bilaterally ranging between 3 mm and 15 mm involving both testicles. Enlarged retroperitoneal lymph nodes were detected on the abdominal computed tomography (CT. Surgical exploration of the testes with a frozen section analysis of the left testicular mass was carried out, and it revealed noncaseating granulomas. CT scan of the chest revealed the classic bilateral hilar and mediastinal lymphadenopathy with reticulonodular infiltrates. The final pathological diagnosis was systemic sarcoidosis with bilateral testicular involvement. Treatment with high-dose corticosteroids resulted in complete resolution of the testicular mass and a significant decrease in the size of the hilar, mediastinal, and retroperitoneal lymphadenopathy.

    Sarcoidosis represents a non-caseating, granulomatous disorder of unknown aetiology whose clinical manifestation is heterogeneous and frequently multisystemic. The portion of patients needing systemic treatment varies: though many patients may undergo spontaneous remission, organ-threatening courses demand systemic therapy. Corticosteroids are the first-line treatment option; however, disease´s progression and/or major corticosteroid side effects may require second- and third-line therapeutics. A current stepwise therapeutic algorithm to sarcoidosis that characterizes additive and alternative therapeutic agents is given in the following review. © Georg Thieme Verlag KG Stuttgart · New York.

    Autoimmune hepatitis/primary biliary cirrhosis overlap syndrome, lymphangioleiomyomatosis/tuberous sclerosis complex (LAM-TSC), and sarcoidosis are three rare diseases. Here we present, to the best of our knowledge, the first description of a patient with the coexistence of these three diseases. A 47-year-old woman affected by LAM-TSC and primary biliary cirrosis/autoimmune hepatitis overlap syndrome. During her follow up a high resolution chest CT scan (HRTC) confirmed the presence of both multiple cysts and micronodular opacities consistent with multifocal micronodular pneumocytes hyperlasia (MMPH), and revealed multiple hilar-mediastinal symmetrical lymphadenopathies suggestive of sarcoidosis. Simultaneously, subcutaneous nodules appeared on her forearm bilaterally. Cutaneous biopsy showed granulomatous dermatitis with sarcoid-like granulomas. A diagnosis of stage I pulmonary sarcoidosis was made. No treatment for sarcoidosis was initiated since the patient had neither systemic involvement, nor respiratory impairment. The presence of more than one rare disease should challenge the concept of a potential common underlying mechanism, since the a priori probability of the concomitant presence of different conditions with different pathogenic mechanisms - especially if rare diseases - is low. We speculate that the dysregulation of the pathway involving mTOR and MAPK and their interaction might play a role in the pathogenesis of other diseases, including sarcoidosis.

    Sarcoidosis is a systemic inflammatory disease clinically characterized by swelling of bilateral hilar lymph nodes and histologically defined by non-caseating epithelioid cell granulomas. Among child cases, a special subtype, called the early-onset sarcoidosis, is known to appear in children younger than 4 years of age and to be characterized by a distinct triad of skin, joint and eye disorders without pulmonary involvement. On the other hand, autosomal dominantly-transmitted disease with a characteristic features similar to those of early-onset sarcoidosis has been reported as Blau syndrome. By a linkage analysis, the responsible gene for Blau syndrome has been mapped close to the IBD (Inflammatory Bowel Disease) 1 locus. After CARD15 (NOD2), originally identified as the susceptibility gene for Crohn's disease, was also proved to be responsible for Blau syndrome, the same gene mutations have been found in sporadic early-onset sarcoidosis cases. Nod2 recognizes a signal from bacterial cell wall component in the cytoplasm of monocytic cells to activate NF-kappaB, and thus can work as an intracellular sensor of bacteria. While the loss-of-function mutations in its LRR domain are associated with Crohn's disease, Blau syndrome and early-onset sarcoidosis are autoinflammatory diseases that are caused by the gain-of-function mutations in its NOD domain.

    Full Text Available Introduction. We report a case of a male patient presented with sarcoid lesions of the iris and conjunctiva, mimicking tuberculosis due to epithelioid cell granulomas with small central necrosis in conjunctival biopsy. Patient. A 25-year-old man was referred to our department for further management of an “iris tumor with iridocyclitis” in his right eye. Initial examination showed an isolated vascular tumor of the iris and ciliary body with anterior uveitis and mutton-fat keratic precipitates, suggesting the diagnosis of a granulomatous disease. Conjunctival biopsy revealed granulomatous epithelioid cell inflammation with small central necrosis without acid-fast bacilli. Extensive systemic examination, including bronchoscopy and transbronchial biopsy, provided the diagnosis of sarcoidosis stage 2 with pulmonary involvement, thus ruling out tuberculosis. Systemic and local steroid therapy was initiated, leading to complete recovery of our patient with complete disappearance of the iris lesion and improvement of the pulmonary function. Conclusion. Although noncaseating epithelioid cell granulomas are typical for sarcoidosis, small central necrosis can be found in some granulomas, leading to presumption of tuberculosis. Extensive systemic checkup in cooperation with other specialists is essential to confirm the correct diagnosis and to initiate the appropriate therapy.

    Pulmonary sarcoidosis which predominantly affects the lower lung fields is relatively rare. We performed this study to clarify the clinical manifestations of this type of sarcoidosis. Over a period of 13 years, we diagnosed pulmonary sarcoidosis in 119 patients. Among these, we reviewed the clinical characteristics of 9 patients (3 men, 6 women, mean age 62 years) with pulmonary lesions predominantly affecting the lower lung fields. Four patients had a history of dust inhalation and 6 had symptoms of dyspnea. All patients had ocular lesions and 5 had cutaneous lesions. Serum KL-6 levels were elevated in all patients, whereas angiotensin-converting-enzyme (ACE) levels were elevated in 3. Pulmonary function tests revealed stenosis in 4 patients, and decreased diffusion capacity in 7. Chest CT findings in the lower lung fields revealed bronchovascular thickening, micronodular opacities in the vessels and chest wall, and interlobular septal thickening in 8 patients; ground-glass opacities in 5; curvilinear shadows in 4; and patchy shadows, traction bronchiectasis, and pleural effusion in 3. Histopathologic findings of lung biopsy specimens featured granulomas in all patients, and pulmonary interstitium fibrosis and small round-cell infiltration in the alveoli of most patients. Patients with sarcoidosis affecting the lower lung fields often had symptoms of dyspnea, extrapulmonary lesions in the eye and/or on the skin, and elevated serum KL-6 levels but not ACE. Chest CT showed findings typical of sarcoidosis, such as lymphatic distribution, but also showed unusual findings such as ground-glass opacities, curvilinear shadows, patchy shadows, traction bronchiectasis and pleural effusion. We speculated that 1 patient with ground-glass opacities and traction bronchiectasis without lymphatic distribution on CT, and fibroblastic foci with active alveolitis histopathologically, had complications of a different type of interstitial pneumonia.

    Full Text Available Sarcoidosis is a multisystem disease that most commonly involves the lungs and the lymph nodes, but with genitourinary tract involvement, can easily mimic testicular cancer with metastasis to the lungs. We describe the case of a 30-year-old African-American male who presented with complaints of a headache, skin lesions, and a scrotal mass. A computed tomography scan of the head showed lesions in the frontotemporal and pons region, causing obstructive hydrocephalus. An ultrasound of the scrotum showed an enlarged epididymis bilaterally as well as a solid hypoechoic ill-defined mass on the right side, separate from the intact testis. Given the high suspicion for testicular malignancy with brain metastasis, a right orchiectomy was completed. The pathology revealed non-caseating necrotizing granulomas that stained negative for tubercular and fungal organisms, which was consistent with sarcoidosis. Additionally, the patient’s skin and central nervous system (CNS lesions improved on steroids that had been started for cerebral edema. Given the predilection of testicular cancer for CNS metastasis, neurosarcoidosis can also be mistaken for testicular cancer metastasis to the CNS, as seen in our case. Differentiating testicular cancer from genitourinary sarcoidosis is difficult but can be clarified using a combination of clinical presentation, epidemiology, serum markers (ACE, AFP, B-HCG, biopsies from skin/lymph nodes, and sometimes imaging. It is critical to differentiate genitourinary sarcoidosis from malignancy, as a misdiagnosis can lead to unnecessary surgical interventions, which have important implications for future fertility. There can also be a coexistence of as well as an association between testicular cancer and sarcoidosis, which should be recognized by health care providers. Both authors contributed equally to the manuscript.

    Sarcoidosis is a multisystem inflammatory disorder of unknown etiology. It shows a great variety of clinical presentation, organ involvement, and disease progression. Lungs and lymphoid system are the most common sites involved with a frequency of 90% and 30%, respectively. Extrapulmonary involvement of sarcoidosis is reported in 30% of patients and abdomen is the most frequent site. Furthermore, peritoneal involvement is extremely rare in sarcoidosis. The case presented here described peritoneal manifestations of sarcoidosis without involvement of lungs. A 78-year-old woman possessing signs of malignancy on blood test and abdominal magnetic resonance imaging underwent laparatomy with a suspicion of ovarian malignancy. The macroscopic interpretation during surgery was peritoneal carcinomatosis. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, peritoneal biopsies, total omentectomy, and appendectomy were performed. Final histopathological result revealed the diagnosis of sarcoidosis. Clinicians must keep in mind that peritoneal sarcoidosis can mimic intra-abdominal malignancies. PMID:26558122

    Sarcoidosis is a multisystem granulomatous disease of unknown origin with pulmonary and extrapulmonary manifestations. Worldwide it is most often diagnosed in the third and fourth decades and most often affects Swedish, Danish and black patients. The association between malignancy and sarcoidosis has not been conclusively proven. Cancer can eventually occur in patients who have an established diagnosis of sarcoidosis for example, in sarcoidosis-lymphoma syndrome. Sarcoidosis can also subsequently develop in an oncology patient. There are multiple obstacles to confirming epidemiologically the linkage between sarcoidosis and malignancy. Histological verification and clinical acumen are needed to avoid misdiagnosis. The 18 fluorodeoxyglucose (18-FDG) PET has failed to provide a non invasive diagnostic method to differentiate neoplasia from benign sarcoid lesions and tissue diagnosis is essential before commencing a new therapeutic intervention in patients with lymphoma.

    Sarcoidosis is a systemic granulomatous disorder with a variety of clinical presentations and radiological appearances. Although it primarily affects the lungs and lymphatics, sarcoidosis potentially involves essentially every organ system. On imaging, sarcoidosis can mimic different disease entities, including primary and metastatic neoplasms, vasculitis, and other granulomatous infections. Definitive diagnosis often requires a combination of clinical, radiological, and histologic information. Imaging plays a crucial role in diagnosis and evaluating response to therapy. This review covers imaging findings in sarcoidosis within each organ system, with an emphasis on the use of imaging in the diagnosis and management of this condition. Copyright © 2016 Elsevier Inc.

    Sarcoidosis is an idiopathic disease which presents in anatomic areas of concern to otorhinolaryngologists. It can cause dysfunction of both auditory and vestibular systems. In patients known previously to have sarcoidosis, this disease should be seriously considered. In patients presenting with otologic disorders and associated facial nerve paralysis or other neuropathies, uveitis, granulomatous meningitis or diabetes insipidus, sarcoidosis should be suspected. An examination of the eyes as well as a chest X-ray is imperative. Sudden and fluctuating neurosensory hearing loss has been reported. There is a great need for the study of temporal bones from sarcoidosis patients.

    Gingivitis due to sarcoidosis is a relatively rare condition. Gingivitis or isolated gingival involvement may be the first sign of systemic sarcoidosis. We report the case of a 37 year-old woman with isolated gingivitis due to sarcoidosis confirmed by biopsy. Following treatment with a systemic corticosteroid (prednisolone 40 mg/day), all clinical and radiologic findings were completely improved. In cases of chronic and intractable gingivitis, systemic sarcoidosis should be suspected. It should be confirmed with a biopsy, and the patient should be referred to a chest disease clinic to exclude other organ involvement. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Abstract Background Sarcoidosis is a granulomatous disorder of unknown etiology. The term of immunoangiostasis has been addressed by various studies as potentially involved in the disease pathogenesis. The aim of the study was to investigate the expression of the master regulator of angiogenesis hypoxia inducible factor (HIF-1a – vascular endothelial growth factor (VEGF- inhibitor of growth factor 4-(ING4 - axis within sarcoid granuloma. Methods A total of 37 patients with sarcoidosis stages II-III were recruited in our study. Tissue microarray technology coupled with immunohistochemistry analysis were applied to video-assisted thoracoscopic surgery (VATS lung biopsy samples collected from 37 sarcoidosis patients and 24 controls underwent surgery for benign lesions of the lung. Computerized image analysis was used to quantify immunohistochemistry results. qRT-PCR was used to assess HIF-1a and ING4 expression in 10 sarcoidosis mediastinal lymph node and 10 control lung samples. Results HIF-1a and VEGF-ING4 expression, both in protein and mRNA level, was found to be downregulated and upregulated, respectively, in sarcoidosis samples compared to controls. Immunohistochemistry coupled with computerized image analysis revealed minimal expression of HIF-1a within sarcoid granulomas whereas an abundant staining of ING4 and VEGF in epithelioid cells was also visualized. Conclusions Our data suggest an impairment of the HIF-1a – VEGF axis, potentialy arising by ING4 overexpression and ultimately resulting in angiostasis and monocyte recruitment within granulomas. The concept of immunoangiostasis as a possible protection mechanism against antigens of infectious origin needs further research to be verified.

    2012-08-01

    Full Text Available Abstract Introduction Sarcoidosis is a multi-systemic disorder of unknown origin and most commonly affects the lungs. Diagnosis relies on the presence of non-caseating granulomas on histologic specimens. In high-resolution computed tomography, the most characteristic findings are peribronchovascular thickening, perilymphatic nodular distribution, and bilateral hilar adenopathy. Confluent nodular opacities or large masses are rare manifestations of the disease. It is well recognized that sarcoidosis can mimic infectious, malignant, and granulomatous conditions. Here, we report a case with a high initial index of suspicion for lung malignancy in terms of clinical, lung imaging, and endoscopic findings. Case presentation A 65-year-old Caucasian woman, lifelong non-smoker with an unremarkable medical history, presented with a 10-month history of progressive breathlessness, dry cough, fatigue, arthralgias, and mild weight loss. The only significant clinical finding was bilateral enlargement of auxiliary lymph nodes. High-resolution computed tomography revealed a soft tissue density mass at the right hilum which was surrounding and narrowing airways and vascular components, nodules with vascular distribution, enlarged mediastinal lymph nodes, and pericardial effusion. Our patient underwent a bronchoscopy, which revealed the presence of submucosal infiltration and narrowing of the right upper bronchus. Endobronchial biopsies showed non-caseating granulomas. As local sarcoid reactions with non-caseating granulomas can be observed near tumors, our patient underwent video-assisted thoracoscopy and surgical removal of an auxiliary lymph node, both of which confirmed the presence of non-caseating granulomas and the diagnosis of sarcoidosis. She was treated with steroids with improvement of clinical and imaging findings. However, while on a maintenance dose, she presented with a pleural effusion, which, after the diagnostic work-up, proved to be sarcoidosis

    The Kveim test provides a useful model for the ultrastructural study of developing epithelioid cell granulomas in man. We present a controlled prospective study in which 140 patients with possible sarcoidosis had two simultaneous Kveim tests, one being biopsed at a varying interval and the other at the usual 28 days: 52 patients showed a positive test. Controls were provided by the 88 negative tests, Kveim biopsis from 12 healthy subjects, and biopsies of normal spleen injection sites in a further 12 sarcoid patients. In all three groups the initial response (3 to 5 days) was macrophage influx. From 8 to 10 days, in developing positive tests only, mononuclear cells with abundant rough endoplasmic reticulum appeared. Mature epithelioid cells were seen at 12 to 14 days, when lymphocyte numbers and lymphocyte-histiocyte interactions were at a maximum. Epithelioid cells showed marked secretory activity; the ultrastructural features of the developing epithelioid cell vacuoles are identical to those seen in exocrine cells. Mast cells are not involved in the development of granulomas.

    A 40-year-old man presented in January 2001 with multiple purple plaques and nodules, which had been present on the back for approximately 3 years. The lesions had gradually extended over the face, trunk and proximal extremities. He had no symptoms except occasional mild pruritus. The patient was in good health and was on no medications. Physical examination revealed multiple violaceous to brown, indurated, 5-50-mm, round to oval plaques on the face, arms, shoulders, and back (Fig. 1), as well as a solitary lesion on the right thigh. Surface telangiectases were noted, especially on the shoulder lesions. There was no scaling or ulceration. Routine laboratory tests were unremarkable. In April 1999, another medical center performed a biopsy of what they thought was sarcoidosis. The results were reported as "possible angiolymphoid hyperplasia with eosinophilia." With the possibility of granuoma faciale (GF) in mind, another skin biopsy was obtained from a facial lesion. This revealed a diffuse, relatively dense infiltrate of neutrophils, eosinophils and mononuclear inflammatory cells in dermis with an obvious Grenz zone (Fig. 2). Pilar units were intact, and endothelial cell swelling was present (Fig. 3). Retrospective evaluation of the initial biopsy, taken from the back, revealed the same changes, and helped confirm the diagnosis of GF. The patient was treated with liquid nitrogen for 20 s followed immediately by intralesional triamcinolone acetonide (5 mg/ml). This treatment was repeated every 4 weeks for three courses, resulting in partial resolution of the lesions.

    Nerve involvement developed in a patient with granuloma annulare, as evidenced by a perineural infiltrate of histiocytes in the dermis. The histopathologic pattern was suggestive of leprosy. No mycobacteria were observed, and neurologic testing was normal. To determine whether inflammation of the nerves or perineural tissue is common in granuloma annulare, we studied the cutaneous nerves in skin biopsy specimens from 14 patients with granuloma annulare. Sections were stained with hematoxylin-eosin to highlight inflammatory cells and with S-100 to identify cutaneous nerves. No inflammation around nerves was found in 12 specimens, abutting granulomatous inflammation was found in 1 specimen, and enveloping granulomatous inflammation was found in 1 specimen. No nerves were infiltrated by inflammatory cells. Perineural granulomatous inflammation resembling the perineural infiltrate of leprosy appears to be an uncommon characteristic of granuloma annulare. Clinical correlation and acid-fast stains can assist in establishing the correct diagnosis.

    Full Text Available Eosinophilic granuloma is a rare disease which is difficult to diagnose clinically and radiographically. Localized Langerhans′ cell histiocytosis, previously known as eosinophilic granuloma, mainly affects the skull, mandible, vertebrae, pelvis and ribs in children and the long bones of adults. We present a case report of a female who developed pain and swelling over the left mandibular region, and was later diagnosed as eosinophilic granuloma, which after administration of intralesional corticosteroid with surgical enucleation showed positive response. This disease is of importance to dental professionals because early clinical signs can occur in the jaw and can cause extensive destruction of the periodontal tissues and bone. The purpose of this case report is to describe a case of eosinophilic granuloma with emphasis on conservative approach for the treatment and the radiographic changes observed during and after the treatment.

    Equine sarcoidosis is a rare disorder usually characterized by exfoliative dermatitis, moderate to severe wasting, and sarcoidal granulomatous inflammation of multiple organ systems. It has an unknown aetiopathogenesis. The condition is not related to equine sarcoid. This case report describes generalized cutaneous and systemic sarcoidosis in an 11-year-old Trakehner mare (case A) and in a 7-year-old Dutch Warmblood gelding (case B). Case A was presented with cutaneous sarcoidosis on the head and body and was diagnosed on the basis of histological examination of skin. Case B presented with multiple subcutaneous nodules (2-15 cm in diameter) and the diagnosis was established at postmortem examination. Both horses showed distinctive histology of the skin with extensive lymphohistiocytic infiltration and Langhans-type multinucleated giant cells. Haematology and biochemistry revealed a normal total white blood cell count with a right shift in both horses. Case B was anaemic and had a slightly elevated total protein concentration with hyperglobulinaemia. Both horses were unresponsive to corticosteroids and were euthanized.

    Bone sarcoidosis is rare manifestation of disease usually accompanied with pulmonary involvement. Until today, exact prevalence of bone sarcoidosis is not known, since reported prevalence varies widely depending on the studied population and the used diagnostic techniques. To determine the prevalence of bone involvement and distribution pattern in active chronic sarcoidosis by using FDG PET/CT. Between January 2010 and December 2011, 98 patients with chronic sarcoidosis and presence of prolonged symptoms or other findings suggestive of active disease were referred to FDG PET/CT examination. Active disease was found in 82 patients, and they all were screened for presence of bone sarcoidosis on FDG PET/CT. All patients also underwent MDCT and assessment of serum ACE level. Bone sarcoidosis was present in 18/82 patients with active sarcoidosis. FDG uptake in bones was focal in 8 (44.4%), diffuse in 6 (33.3%) and both diffuse and focal in 4 (22.2%) patients. CT indicated bone abnormalities only in 5% patients. Osseous involvement was present in: pelvis (61.1%), vertebrae (44.4%), ribs (27.8%) and bone marrow (16.7%). Some patients had two or more locations of disease. Follow-up FDG PET/CT showed normal findings in two patients, same localization of active disease in four patients and progression of disease in one. In patients with active chronic sarcoidosis 22% of patients had osseous abnormalities on FDG PET/CT that mostly were not detected on CT.

    Haemoptysis rarely occurs in sarcoidosis. Most cases usually occur in patients with advanced disease and major fibrosis. We observed 6 cases including 5 with fibrosis and 1 with inaugural unilateral lymph node involvement. Haemoptysis is a sign of gravity since it is the second most frequent cause of death described in the literature. In our series 4 of the 6 cases were fatal. Aspergillus colonization of a cavity is the most frequently found aggravating factor. Ideally, surgery is indicated but usually cannot be performed due to the patients respiratory function and the extent of the lesions. Oral drugs have little effect. Certain authors have had success with local, initially intrabronchic anti-aspergillus treatment. CT-guided application is often helpful. Embolization may stop the bleeding but in the long-term, a more or less voluminous haemoptysis often recurs. Other causes of bleeding are rare. Systemic hypervascularization of sarcoidosis lesions has been proposed as one mechanism other than infection. The cause may also be a simple granuloma. Symptomatic initial treatment by embolization is also proposed in these cases. Finally, massive haemoptysis can occur by erosion of the pulmonary artery due to a necrotic sarcoidosis lesion. In our series, surgery was impossible in three patients who died. In the three others, embolization was possible in 2 and the third underwent successful surgery.

    Sarcoidosis is a systemic granulomatous disease of unknown aetiology that most commonly affects the lungs. Although elevated levels of regulatory T cells (Tregs ) have been reported, the extent to which they play a role in sarcoidosis pathogenesis remains unclear. Tumour necrosis factor (TNF) is thought to be one of the driving forces behind granuloma formation, illustrated by the efficacy of infliximab in severe sarcoidosis. Tregs express TNF receptor 2 (TNFR2) highly. Here, we examined the influence of infliximab therapy on Tregs and (soluble) TNFR2 levels in sarcoidosis, and correlated these with response to therapy. We observed that relative frequencies of Tregs were significantly higher in patients (n = 54) compared to healthy controls (n = 26; median 6·73 versus 4·36%; P infliximab therapy, suggesting a pathophysiological role of this T cell subset. Interestingly, sTNFR2 levels at baseline differed significantly between responders and non-responders, making it a potential marker in predicting which patients might benefit from infliximab. © 2016 British Society for Immunology.

    Angiogenesis/angiostasis regulated by hypoxia inducible factor-1A (HIF-1A)/vascular endothelial growth factor (VEGF)/inhibitor of growth protein 4 (ING-4) axis may be crucial for the course and outcome of sarcoidosis. Overexpression of angiogenic factors (activation of VEGF through HIF-1A) may predispose to chronic course and lung fibrosis, whereas immunoangiostasis (related to an overexpression of inhibitory ING-4) may be involved in granuloma formation in early sarcoid inflammation, or sustained or recurrent formation of granulomas. In this work we investigated gene expression of HIF-1A, VEGF and ING-4 in bronchoalveolar fluid (BALF) cells and in peripheral blood (PB) lymphocytes of sarcoidosis patients (n=94), to better understand mechanisms of the disease and to search for its biomarkers. The relative gene expression level (RQ value) was analyzed by qPCR. The results were evaluated according to the presence of lung parenchymal involvement (radiological stage I vs. II-IV), acute vs. insidious onset, lung function tests, calcium metabolism parameters, percentage of lymphocytes (BALL%) and BAL CD4+/CD8+ in BALF, age, and gender. In BALF cells, the ING-4 and VEGF RQ values were increased, while HIF-1A expression was decreased. In PB lymphocytes all studied genes were overexpressed. Higher expression of HIF-1A in PB lymphocytes of patients with abnormal spirometry, and in BALF cells of patients with lung volume restriction was found. VEGF gene expression in BALF cells was also higher in patients with abnormal spirometry. These findings were in line with previous data on the role of HIF-1A/VEGF/ING-4 axis in the pathogenesis of sarcoidosis. Up-regulated HIF-1A and VEGF genes are linked to acknowledged negative prognostics.

    Dysphagia is a rare manifestation of sarcoidosis. It is more commonly the result of esophageal compression by enlarged mediastinal lymph nodes rather than direct esophageal involvement and rarely secondary to neurosarcoidosis and oropharyngeal dysphagia. We report a 54 year old female presenting with a six month history of worsening dysphagia. She denied respiratory symptoms. Physical exam was normal. ESR was 61 mm/hr. Serum ACE level was 65 mcg/L. Chest X-ray was normal. Esophagram revealed a large amount of contrast pooling in pharyngeal recesses with intermittent laryngeal aspiration. Swallow videofluorography showed a decreased retraction of the base of the tongue, limited laryngeal elevation, and a large amount of contrast pooling in pharyngeal recesses with intermittent laryngeal aspiration. EGD showed a normal opening of the upper esophageal sphincter and the cricopharyngeus appeared normal. Proximal esophageal biopsies were normal. Brain MRI with gadolinium was normal. Lumbar puncture was performed. CSF showed a moderate pleocytosis, a WBC count of 19 with 97% lymphocytes, an elevated total protein level of 85 mg/dl (15-60). Neck CT scan showed no oropharyngeal tissue thickening or infiltration, no masses or enlarged lymph nodes. Chest CT scan showed enlarged intrathoracic lymph nodes and no esophageal compression. Bronchoscopy showed the vocal cords to be intact, and the CD4/CD8 ratio in BAL was 5.3. Subcarinal lymph node EBUS biopsy revealed non caseating granulomas. The patient was started on IV methylprednisolone. Three days later, the swallow videofluorography showed a near complete response to steroids. The patient tolerated regular consistency diet with thin liquids, and she was discharged on a slow taper of prednisone over a period of three months. A unique case of isolated dysphagia unmasking bulbar neurosarcoidosis and pulmonary sarcoidosis is herein reported. Copyright © 2014 Arab Journal of Gastroenterology. Published by Elsevier Ltd. All

    To investigate whether lacrimal gland uptake on (67)Ga-gallium citrate scintigraphy correlates with histopathologic evidence of sarcoidosis. A retrospective, pilot study of 31 patients with suspected sarcoidosis who underwent gallium scintigraphy and lacrimal gland biopsy. Lacrimal gland gallium uptake was assessed by subjective visual scoring (SVS) and lacrimal uptake ratio (LUR). Eleven (36%) patients had lacrimal gland biopsies containing noncaseating granulomas. A statistically significant correlation was found between lacrimal gland gallium uptake and biopsy positivity using SVS (p = 0.03) or LUR (p = 0.01). Using SVS, biopsy positivity rate increased from 0 to 50% in patients with mild to intense uptake. Using LUR, biopsy positivity rate increased linearly as the ratio increased from 13% (LUR  8). Lacrimal biopsy positivity rate significantly correlated with gallium uptake on scintigraphy. Both SVS and LUR methods appear to correlate with histologic results and may potentially aid in patient selection for biopsy.

    Full Text Available Primary mammary fibromatosis is a rare skin condition which can arise after trauma or previous surgery. The exact etiology is unknown. Very few cases have been reported in literature and the main emphasis is to differentiate this condition from breast carcinoma. We report here an unusual case of a 60 year old female who presented with skin lesion which clinically looked sarcoid with history suggestive of sarcoidosis, but on histopathology fibromatosis of breast was revealed. Complete work up ruled out any carcinomatous changes. Surgical excision of the lesion was done with no recurrence seen in one year follow up period.

    The molecular basis of sarcoidosis phenotype heterogeneity and its relationship to effective treatment of sarcoidosis have not been elucidated. Peripheral samples from sarcoidosis subjects who participated in a Phase II study of golimumab [anti-tumour necrosis factor (TNF)-α] and ustekinumab [anti-interleukin (IL)-12p40] were used to measure the whole blood transcriptome and levels of serum proteins. Differential gene and protein expression analyses were used to explore the molecular differences between sarcoidosis phenotypes as defined by extent of organ involvement. The same data were also used in conjunction with an enrichment algorithm to identify gene expression changes associated with treatment with study drugs compared to placebo. Our analyses revealed marked heterogeneity among the three sarcoidosis phenotypes included in the study cohort, including striking differences in enrichment of the interferon pathway. Conversely, enrichments of multiple pathways, including T cell receptor signalling, were similar among phenotypes. We also identify differences between treatment with golimumab and ustekinumab that may explain the differences in trends for clinical efficacy observed in the trial. We find that molecular heterogeneity is associated with sarcoidosis in a manner that may be related to the extent of organ involvement. These findings may help to explain the difficulty in identifying clinically efficacious sarcoidosis treatments and suggest hypotheses for improved therapeutic strategies. © 2017 British Society for Immunology.

  1. Radiation therapy of midline granuloma

    1976-01-01

    During a 15-year period, 10 patients with well-documented midline granuloma were treated with high-dose, deep local irradiation and followed for extended periods of time. Long-term remissions were achieved in 7 patients, with a mean (+- SEM) survival postirradiation of 7.4 (+-1.4) years in the 6 patients still alive. True midline granuloma, which is a localized, destructive, inflammatory process of the upper airways, can be distinguished from Wegener's granulomatosis and neoplasms of the upper respiratory tract by several clinicopathologic criteria. The cause of midline granuloma is unknown, but it most likely represents an abnormal accelerated hypersensitivity reaction to an unknown antigen(s). Although serious complications of high-dose local irradiation to the upper airways can occur, the risk is warranted because of the high, long-term remission rate in this previously uniformly fatal disease.

    2013-01-01

    Molecular mimicry seems to be the most important factor for the heterogeneous clinical presentation and the immunopathogenesis of sarcoidosis. Molecular mimicry may occur as a result of altered activity of oncogenes. This can lead to crossed-type mediated body reactions targeting structurally similar sections or regions from the tissue homeostasis. Available data suggest that structural analogy between tissue and foreign or de novo-appearing peptides is not always reliable. Nevertheless, lack of amino acid identity between the tissue and the de novo-generated tumour antigens does not exclude the phenomenon of molecular mimicry as the major generator of sarcoidosis. There is growing evidence of the mimicry phenomena, caused not only by the similarity between the amino acids but also between the elements which connect segments in the immunological cascade and which may also be affected by external factors. Molecular mimicry may occur between two identified peptides having similar antigenic surfaces (transitory or not), in the absence of a primary homology in amino acid sequence. As far as tumour antigens are concerned, a structural analogy to the de novo-appearing tumour antigens is more likely than transitory imitation resulting from the additional interference of other physical forces. Further research should be performed to confirm, or reject, the transitory imitation thesis or hypothesis.

    Although, the diagnosis and evaluation of sarcoidosis has traditionally remained confined to the chest, its multi-system nature has been widely recognized. Radiological features of pulmonary sarcoidosis are well known but extra-pulmonary manifestations can produce a plethora of non-specific imaging findings that can affect subcutaneous tissue, and the neurological, cardiac, gastrointestinal, urological, liver, spleen, and skeletal systems. In the literature, there are various case reports and specific system reviews but there are few reviews that encompass all the extra-pulmonary manifestations. In this paper, we comprehensively review the imaging features of extra-pulmonary sarcoidosis with characteristic features as well as atypical presentations. In addition, we discuss the emerging role of nuclear medicine in sarcoidosis.

    Gastric involvement is the least rare among digestive localizations of sarcoidosis, as well in adults as in children. When it is to be seen at the beginning of the disease, it may cause difficulties in the diagnostic, especially with Crohn's disease. Gastric ulcers were detected in a 12 year-old girl, of African origin, who complained about epigastric pain. Eighteen months later, diarrhea, poor growing, uveitis and inflammatory biological signs led to a probable diagnostic of Crohn's disease. Endoscopy seemed to confirm this diagnostic with granulomatous lesions on gastric biopsies. The absence of radiological anomalies of the digestive tract and the poor efficiency of the medical treatment led to question this diagnosis and to assert that of sarcoidosis. This case allows to emphasize the rare involvement of the digestive tract in sarcoidosis and the aspects common both to Crohn's disease and sarcoidosis.

    2014-11-06

    Granulomas, organized aggregates of immune cells, are a defining feature of tuberculosis (TB). Granuloma formation is implicated in the pathogenesis of a variety of inflammatory disorders. However, the tuberculous granuloma has been assigned the role of a host protective structure which "walls-off" mycobacteria. Work conducted over the past decade has provided a more nuanced view of its role in pathogenesis. On the one hand, pathogenic mycobacteria accelerate and exploit granuloma formation for their expansion and dissemination by manipulating host immune responses to turn leukocyte recruitment and cell death pathways in their favor. On the other hand, granuloma macrophages can preserve granuloma integrity by exerting a microbicidal immune response, thus preventing an even more rampant expansion of infection in the extracellular milieu. Even this host-beneficial immune response required to maintain the bacteria intracellular must be tempered, as an overly vigorous immune response can also cause granuloma breakdown, thereby directly supporting bacterial growth extracellularly. This review will discuss how mycobacteria manipulate inflammatory responses to drive granuloma formation and will consider the roles of the granuloma in pathogenesis and protective immunity, drawing from clinical studies of TB in humans and from animal models--rodents, zebrafish, and nonhuman primates. A deeper understanding of TB pathogenesis and immunity in the granuloma could suggest therapeutic approaches to abrogate the host-detrimental aspects of granuloma formation to convert it into the host-beneficial structure that it has been thought to be for nearly a century.

    Sarcoidosis is a systemic granulomatous disorder of unknown aetiology with a wide spectrum of radiological appearances and almost invariably pulmonary involvement. Lung involvement accounts for most of the morbidity and much of the mortality associated with sarcoidosis. Imaging contributes significantly to the diagnosis and management of patients with sarcoidosis. In typical cases, chest radiography may be sufficient to establish the diagnosis with little margin of error and CT is not necessary. However, CT can play a critical role in several clinical settings: atypical clinical and/or radiographic findings; normal or near-normal chest radiograph but clinical suspicion of sarcoidosis; and detection of complications. Moreover, in many patients, CT findings are atypical and unfamiliar to most radiologists (e.g. sarcoidosis mimicking other lung diseases and vice versa), and in these cases histological confirmation of the diagnosis is recommended. CT is also useful in assessing disease extent and may help to discriminate between reversible and irreversible lung disease, thus providing critical prognostic information. This review concentrates on the more difficult imaging aspects of sarcoidosis, in particular differential diagnosis and disease complications. (orig.)

    Severe thoracic sarcoidosis includes manifestations with significant clinical and functional impairment and a risk of mortality. Severe thoracic sarcoidosis can take on various clinical presentations and is associated with increased morbidity. The purpose of this article was to describe the CT findings in severe thoracic sarcoidosis and to explain some of their mechanisms. Subacute respiratory insufficiency is a rare and early complication due to a high profusion of pulmonary lesions. Chronic respiratory insufficiency due to pulmonary fibrosis is a frequent and late complication. Three main CT patterns are identified: bronchial distortion, honeycombing and linear opacities. CT can be helpful in diagnosing some mechanisms of central airway obstruction such as bronchial distortion due to pulmonary fibrosis or an extrinsic bronchial compression by enlarged lymph nodes. An intrinsic narrowing of the bronchial wall by endobronchial granulomatous lesions may be suggested by CT when it shows evidence of bronchial mural thickening. Pulmonary hypertension usually occurs in patients with end-stage pulmonary disease and is related to fibrotic destruction of the distal capillary bed and to the resultant chronic hypoxemia. Several other mechanisms may contribute to the development of pulmonary hypertension including extrinsic compression of major pulmonary arteries by enlarged lymph nodes and secondary pulmonary veno-occlusive disease. Aspergilloma colonization of a cavity is the main cause of hemoptysis in sarcoidosis. Other rare causes are bronchiesctasis, necrotizing bronchial aspergillosis, semi-invasive pulmonary aspergillosis, erosion of a pulmonary artery due to a necrotic sarcoidosis lesion, necrosis of parenchymal sarcoidosis lesions and specific endobronchial macroscopic lesions.

    Objective. Granuloma annulare is an uncommon benign inflammatory dermatosis characterized by the formation of dermal papules with a tendency to form rings. There are several clinically distinct forms. The subcutaneous form is the most frequently encountered by radiologists, with the lesion presenting as a superficial mass. There are only a few scattered reports of the imaging appearance of this entity in the literature. We report the radiologic appearance of five cases of subcutaneous granuloma annulare. Design and patients. The radiologic images of five patients (three male, two female) with subcutaneous granuloma annulare were retrospectively studied. Mean patient age was 6.4 years (range, 2-13 years). The lesions occurred in the lower leg (two), foot, forearm, and hand. MR images were available for all lesions, gadolinium-enhanced imaging in three cases, radiographs in four, and bone scintigraphy in one. Results. Radiographs showed unmineralized nodular masses localized to the subcutaneous adipose tissue. The size range, in greatest dimension on imaging studies, was 1-4 cm. MR images show a mass with relatively decreased signal intensity on all pulse sequences, with variable but generally relatively well defined margins. There was extensive diffuse enhancement following gadolinium administration. Conclusion. The radiologic appearance of subcutaneous granuloma annulare is characteristic, typically demonstrating a nodular soft-tissue mass involving the subcutaneous adipose tissue. MR images show a mass with relatively decreased signal intensity on all pulse sequences and variable but generally well defined margins. There is extensive diffuse enhancement following gadolinium administration. Radiographs show a soft-tissue mass or soft-tissue swelling without evidence of bone involvement or mineralization. This radiologic appearance in a young individual is highly suggestive of subcutaneous granuloma annulare. (orig.) With 3 figs., 17 refs.

    Only case reports or studies of small series of patients have focused on granuloma faciale (GF). We sought to describe the clinicopathologic characteristics of GF in a large series of patients. We conducted a retrospective analysis of 66 patients and 73 skin specimens. GF mostly presented as reddish plaques or nodules in middle-aged adults. One third of patients had multiple sites involved and 5 patients had extrafacial lesions. A clinical diagnosis of GF was made in only 10 cases; sarcoidosis, lymphoma, lupus, and basal cell carcinoma were the main differential diagnoses. The most frequent histopathologic features were the presence of a grenz zone, neutrophils, and telangiectases. Vascular changes were frequent, although necrotizing vasculitis appeared to be rare. There was often an association of acute and chronic inflammatory patterns, suggesting that GF follows a chronic history with recurrent acute phases, rather than distinct successive acute and chronic stages. In this retrospective study, a reliable analysis of the outcome of patients could not be performed. Results of direct immunofluorescence tests and laboratory investigations were lacking in many cases. GF is often clinically misdiagnosed; its morphologic spectrum is broader than usually described and includes a lack of eosinophils, the presence of vascular changes with rare vessel wall necrosis, and associated acute and chronic inflammatory patterns.

    Blau syndrome (BS) and early-onset sarcoidosis (EOS) are both systemic granulomatous disease evoked by the mutated NOD2. It occurs in children younger than 4 years of age and is characterized by a distinct triad of skin, joint, and eye disorders without apparent pulmonary involvement. NOD2 encodes an intracellular receptor for muramyl dipeptide (MDP), the common component of bacterial cell wall peptidoglycan, and is expressed in cytoplasm of monocytic cells and epithelial cells. While its loss-of-function mutations are recognized in Crohn's disease, the mutations observed in BS/EOS are gain-of-function, and induced MDP-independent basal NF-kappaB activation. But we still do not know the precious molecular mechanism how the activation of NOD2 induces granuloma formation in the skin, joints and eyes.

  6. Human schistosomiasis mansoni: studies on in vitro granuloma modulation

    Directory of Open Access Journals (Sweden)

    Juçara C. Parra

    1992-01-01

    Full Text Available Infection with Schistosoma mansoni induces humoral and T cell mediated responses and leads to delayed hipersensitivity that results in granulomatous inflamatory disease around the parasite eggs. Regulation of these responses resulting in a reduction in this anti-egg inflamatory disease is appsrently determined by idiotypic repertoires of the patient, associated with genetic background and multiple external factors. We have previously reported on idiotype/anti-idiotype-receptor transactions in clinical human schistosomiasis. These findings support a hypothesis that anti-SEA cross-reactive idiotypes develop in some patients during the course of a chronic infection and participate in regulation of anti-SEA cellular immune responses. We repport here on experiments wich extend those observations to the regulation of granulomatous hypersensitivity measured by an in vitro granuloma model. T cells from chronic intestinal schistosomiasis patients were stimulated in vitro with anti-SEA idiotypes and assayed in an autologous in vitro granuloma assay for modulation of granuloma formation. These anti-SEA idiotype reactive T cells were capable of regulating autologous in vitro granuloma formation. This regulatory activity, initiated with stimulatory anti-SEA idiotypic antibodies, was antigenically specific and was dependent on the present of intact (F(ab'2 immunoglobulin molecules. The ability to elicit this regulatory activity appears to be dose dependent and is more easily demonstrated in chronically infected intestinal patients or SEA sensitized individuals. These data support the hypothesis that anti-SEA cross reactive idiotypes are important in regulating granulomatous hypersensitivy in chronic intestinal schistosomiasis patients and these cross-reactive idiotypes appear to play a major role in cell-cell interactions which result in the regulation of anti-SEA cellular immune responses.

    Sarcoidosis is a multisystem granulomatous disease affecting nervous system in 5% to 10% of patients. Magnetic resonance imaging (MRI) is accepted as the most sensitive method for detecting neurosarcoidosis. However, the most common findings in MRI are the nonspecific white matter lesions, which may be unrelated to sarcoidosis and can occur because of hypertension, diabetes mellitus, smoking, and other inflammatory or infectious disorders, as well. Autopsy studies report more frequent neurological involvement than the ante mortem studies. The aim of this study is to assess electroencephalography (EEG) in sarcoidosis patients without neurological findings in order to display asymptomatic neurological dysfunction. We performed EEG on 30 sarcoidosis patients without diagnosis of neurosarcoidosis or prior neurological comorbidities. Fourteen patients (46.7%) showed intermittant focal and/or generalized slowings while awake and not mentally activated. Seven (50%) of these 14 patients with EEG slowings had nonspecific white matter changes while the other half showed EEG slowings in the absence of MRI changes. We conclude that EEG slowings, when normal variants (psychomotor variant, temporal theta of elderly, frontal theta waves) are eliminated, may be an indicator of dysfunction in brain activity even in the absence of MRI findings. Hence, EEG may contribute toward detecting asymptomatic neurological dysfunction or probable future neurological involvement in sarcoidosis patients. © EEG and Clinical Neuroscience Society (ECNS) 2016.

    Pleural involvement in sarcoidosis is uncommon and appears in several forms. To document the incidence and characteristics of pleural effusion in sarcoidosis patients, a review of the cases diagnosed in our centre between January 2001 and December 2012 was carried out. One hundred and ninety-five patients with sarcoidosis were identified; three (two men and one woman) presented with unilateral pleural effusion (1.5%): one in the right side and two in the left. Two were in stageii and one was in stageiv. The pleural fluid of the two patients who underwent thoracocentesis was predominantly lymphocytic. One of these patients presented chylothorax and the other had high CA-125levels. In general, these effusions are lymphocyte-rich, paucicellular, serous exudates (sometimes chylothorax) and contain proportionally higher levels of protein than LDH. Most cases are treated with corticosteroids, although it may resolve spontaneously. Copyright © 2013 SEPAR. Published by Elsevier Espana. All rights reserved.

    Sarcoidosis is a systemic granulomatous disease of unknown origin that mainly involves lung and skin, but rarely involves subcutaneous tissue. While some studies have reported on CT or MR imaging findings of subcutaneous sarcoidosis, there is only one report on sonographic findings of subcutaneous sarcoidosis, recently published in the US. Familiarity with ultrasonographic findings of subcutaneous sarcoidosis might be helpful for the early diagnosis in patient with palpable nodules and image follow-up for subcutaneous sarcoidosis. Here we report on the sonographic appearance of subcutaneous sarcoidosis involving dermal and subcutaneous tissue over axilla and sole, a case diagnosed as sarcoidosis and improved by steroid treatment, along with a review of the relevant literature.

  16. Histological assessment of granulomas in natural and experimental Schistosoma mansoni infections using whole slide imaging.

    Directory of Open Access Journals (Sweden)

    Kátia B Amaral

    Full Text Available The pathology of schistosomiasis mansoni, a neglected tropical disease of great clinical and socioeconomic importance, results from the parasite eggs that become trapped in host tissues, particularly in the liver and intestines. Continuous antigenic stimulation from these eggs leads to recruitment of inflammatory cells to the sites of infection with formation of periovular granulomas. These complex structures have variable size and composition and are the most striking histopathological feature of schistosomiasis mansoni. However, evaluation of granulomas by conventional microscopy methods is time-consuming and limited, especially in large-scale studies. Here, we used high resolution Whole Slide Imaging (WSI, which allows fast scanning of entire histological slides, and multiple morphometric evaluations, to assess the granulomatous response elicited in target organs (liver, small and large intestines of two models of schistosomiasis mansoni. One of the advantages of WSI, also termed virtual microscopy, is that it generates images that simultaneously offer high resolution and a wide field of observation. By using a model of natural (Nectomys squamipes, a wild reservoir captured from endemic areas in Brazil and experimental (Swiss mouse infection with Schistosoma mansoni, we provided the first detailed WSI characterization of granulomas and other pathological aspects. WSI and quantitative analyses enabled a fast and reliable assessment of the number, evolutional types, frequency and areas of granulomas and inflammatory infiltrates and revealed that target organs are differentially impacted by inflammatory responses in the natural and experimental infections. Remarkably, high-resolution analysis of individual eosinophils, key cells elicited by this helminthic infection, showed a great difference in eosinophil numbers between the two infections. Moreover, features such as the intestinal egg path and confluent granulomas were uncovered. Thus, WSI may

    Clinically evident sarcoidosis involving the heart has been noted in at least 2 to 7% of patients with sarcoidosis, but occult involvement is much higher (> 20%). Cardiac sarcoidosis is often not recognized antemortem, as sudden death may be the presenting feature. Cardiac involvement may occur at any point during the course of sarcoidosis and may occur in the absence of pulmonary or systemic involvement. Sarcoidosis can involve any part of the heart, with protean manifestations. Prognosis of cardiac sarcoidosis is related to extent and site(s) of involvement. Most deaths due to cardiac sarcoidosis are due to arrhythmias or conduction defects, but granulomatous infiltration of the myocardium may be lethal. The definitive diagnosis of isolated cardiac sarcoidosis is difficult. The yield of endomyocardial biopsies is low; treatment of cardiac sarcoidosis is often warranted even in the absence of histologic proof. Radionuclide scans are integral to the diagnosis. Currently, 18F-fluorodeoxyglucose positron emission tomography/computed tomography and gadolinium-enhanced magnetic resonance imaging scans are the key imaging modalities to diagnose cardiac sarcoidosis. The prognosis of cardiac sarcoidosis is variable, but mortality rates of untreated cardiac sarcoidosis are high. Although randomized therapeutic trials have not been done, corticosteroids (alone or combined with additional immunosuppressive medications) remain the mainstay of treatment. Because of the potential for sudden cardiac death, implantable cardioverter-defibrillators should be placed in any patient with cardiac sarcoidosis and serious ventricular arrhythmias or heart block, and should be considered for cardiomyopathy. Cardiac transplantation is a viable option for patients with end-stage cardiac sarcoidosis refractory to medical therapy. PMID:25007089

    Vasculitis associated with sarcoid granulomas is an uncommon phenomenon. A 72-year-old female presented with an expanding region of circumscribed alopecia and scalp atrophy of 2 months duration. Biopsy showed non-caseating granulomas, dermal thinning, loss of follicles, fibrosis and muscular vessels disrupted by mixed lymphocyte, macrophage and giant-cell infiltrates. Affected vessels had loss and fragmentation of the elastic lamina, fibrous replacement of their walls and luminal stenosis (endarteritis obliterans). Dermal and vascular advential intralymphatic granulomas and lymphangiectases were found by D2-40 expression, suggesting lymphatic obstruction and poor antigen clearance. No evidence of a post-zoster eruption, systemic sarcoidosis or systemic giant-cell arteritis was found. Two years later, prednisone had halted - but not reversed - progression of her alopecia. Review of the literature showed two types of vasculitis associated with sarcoid granulomas: (i) acute, self-limited leukocytoclastic vasculitis and (ii) chronic granulomatous vasculitis (GV). Persistence of non-degradable material or antigen contributes to the pathogenesis of granulomatous inflammation. In this case, lymphatic obstruction probably impeded clearance of nonimmunologic and/or immunologic stimuli permitting and sustaining the development of sarcoid granulomas and sarcoid GV, ultimately causing scarring alopecia and cutaneous atrophy. © 2015 John Wiley & Sons A/S.

    2015-03-01

    Because of the rarity of neuro-ophthalmic sarcoidosis, there are no therapeutic guidelines based on evidence-based medicine for this disorder. Review of literature combined with personal experience. Corticosteroids are the preferred initial therapy for neuro-ophthalmic sarcoidosis. If patients cannot tolerate the requisite dose of corticosteroid needed to control their disease, or if corticosteroids fail to adequately control the disease process, the choices of a second agent are based on the consideration of rapidity of clinical response and the safety profile. Although methotrexate and mycophenolate mofetil are the medications that are often selected after corticosteroid failure, more rapidly acting agents that have been used are infliximab and intravenous cyclophosphamide.

    The present work deals with the structural analysis of Schistosoma mansoni granuloma and the visualization of cellular interaction at an ultrastuctural level in the acute (8 weeks) and chronic (20 weeks) stages of infection, for more detailed understanding of pathophysiology of the disease. Although, S. mansoni granuloma is mediated by T-lymphocytes, yet in this work the macrophage cells and not the lymphocytes represented the main cell type in cellular and fibrocellular granulomas. The cellular and fibrocellular granulomas detected in the acute stage of infection elicited no difference in cellular constituent to those of the chronic stage respectively. Macrophage cells and fibrocytes were the only cell type detected in fibrotic granuloma. The monocytes may be considered the first cell reaching the site of the trapped egg as they formed the first row of cells around the egg. The cellular infiltrate forming the granuloma: monocytes, macrophages, lymphocytes, eosinophils, fibroblasts and plasma cells revealed direct contact or adherence between them and even between the individual cell type, through extending protrusion from the cell membrane of adjacent cells. They constituted an integrated network which encircled the egg. Similar adhesion between inflammatory cells in the blood vessels and between the inflammatory cells and the endothelial cells were displayed. These points of intercellular adhesion appeared as if, not only used for functional communication between the cells, but also for cellular deplacement either in the extracellular matrix or in the blood stream until extravasation. In conclusion, S. mansoni granuloma is a highly organized cellular lesion, in which cell to cell communication occurs through direct cell contact.

The patient was treated with a combination of cryotherapy and intralesional corticosteroids with excellent results.

  3. Mathematical Modeling of Tuberculosis Granuloma Activation

    Full Text Available Tuberculosis (TB is one of the most common infectious diseases worldwide. It is estimated that one-third of the world’s population is infected with TB. Most have the latent stage of the disease that can later transition to active TB disease. TB is spread by aerosol droplets containing Mycobacterium tuberculosis (Mtb. Mtb bacteria enter through the respiratory system and are attacked by the immune system in the lungs. The bacteria are clustered and contained by macrophages into cellular aggregates called granulomas. These granulomas can hold the bacteria dormant for long periods of time in latent TB. The bacteria can be perturbed from latency to active TB disease in a process called granuloma activation when the granulomas are compromised by other immune response events in a host, such as HIV, cancer, or aging. Dysregulation of matrix metalloproteinase 1 (MMP-1 has been recently implicated in granuloma activation through experimental studies, but the mechanism is not well understood. Animal and human studies currently cannot probe the dynamics of activation, so a computational model is developed to fill this gap. This dynamic mathematical model focuses specifically on the latent to active transition after the initial immune response has successfully formed a granuloma. Bacterial leakage from latent granulomas is successfully simulated in response to the MMP-1 dynamics under several scenarios for granuloma activation.

    We describe the first case of mediolateral episiotomic sarcoidosis of the deep vaginal tissue, without involvement of the pulmonary parenchyma or pulmonary symptoms. A 68-year-old female was admitted with a vaginal mass that had developed about 1 month prior. On bimanual examination, we found a painful solid mass approximately 4 cm in diameter on the episiotomy line of the deep vaginal tissue. The patient underwent pelvic magnetic resonance imaging on suspicion of a malignancy, and a vaginal true-cut biopsy was performed. The biopsy specimen exhibited non-caseating, granulomatous inflammation and many multinucleated giant cells, strongly suggesting sarcoidosis. We had excluded other granulomatous diseases; a final diagnosis was made of stage-1 sarcoidosis in the deep vaginal mass. A 3-month course of methotrexate (2.5 mg/week) was commenced to treat a flare-up of rheumatoid arthritis. The vaginal mass resolved.

    We hypothesized that the prevalence of allergic disorders, characterized by the release of type 2 cytokines (IL-4, IL-5, IL-10), would be lower in sarcoidosis in which there is a dominant type 1 immune response (IL-2, interferon-gamma). The objective was to measure the prevalence of atopy and self-reported asthma in patients with sarcoidosis. Sarcoidosis patients (n = 136, 72 M, age range 22-75), recruited in the outpatient setting, completed a modified European Community Respiratory Health Survey. 123 of these patients provided blood for allergy testing. For the cohort as a whole the self-reported prevalence of asthma ever (21.5%) and asthma attack in the last 12 months (7.5%), was high as was wheezing (42.1%), breathlessness with wheeze (22.3%) and use of an asthma medication (13.1%). The prevalence of atopy was 34%. These data are not different from the previously reported prevalence of asthma and atopy in New Zealand. The same prevalence of asthma symptoms and atopy as in the normal population suggests that the immune system is not skewed away from mounting T helper type 2 immune responses in sarcoidosis. © 2011 The Authors.

    The value of high-resolution computed tomography (HRCT) in diagnosing and assessing inflammatory activity in sarcoidosis is well established. The aim of the present study was to address the intra- and inter-observer agreements of the HRCT score by Oberstein et al. [8], and to evaluate the relationship between HRCT findings and disease severity expressed in respiratory functional impairment in sarcoidosis. The clinical records of 80 known sarcoidosis patients visiting the outpatient clinic between January 2000 and August 2001, who underwent a HRCT as well as lung function tests (including exercise testing), were reviewed. Two readers scored the first 60 HRCT images twice. Weighted kappa and intra-class correlation coefficient were used to assess the reliability of the HRCT scoring system. Spearman's rank correlation coefficients and multiple regression analyses were performed to evaluate the relationship between HRCT findings (first reading, reader A) and respiratory functional impairment. Intra- and inter-reader reliability demonstrated good agreement. All HRCT subscores, except enlargement of lymph nodes, were correlated to the FEV{sub 1}, FVC, DLco, Pao{sub 2}max (all p<0.05) and A-aPo{sub 2}max (p <0.001). Furthermore, HRCT abnormalities, but not the chest radiographic stage, were strongly associated with functional parameters. Abnormal changes of lung parenchyma, established by HRCT features, were associated with respiratory functional impairment in sarcoidosis. Moreover, compared with the radiographic stages, HRCT findings appeared to be much more sensitive in depicting respiratory disability, especially abnormal gas exchange. (orig.)

    Sarcoidosis is a multisystem inflammatory disorder characterized by the presence of noncaseating granulomas in involved organs. Prior research has found that sarcoidosis imposes a significant economic burden to U.S. payers. However, the drivers of high health care costs among sarcoidosis patients are unknown. To characterize sarcoidosis patients who were among the top 20% of total health care costs. Patients with a first diagnosis of sarcoidosis between January 1, 1998, and March 31, 2015 (index date) were selected from a deidentified privately insured administrative claims database. Study patients must have at least 12 months of continuous health plan enrollment prior to the index date. High-cost patients were those in the top 20% of total health care costs during the 12 months following the index date (follow-up period), and the remaining patients were classified as lower-cost patients. Patient characteristics, comorbidities, health care resource use, and health care costs in the study period were compared between the high-cost and lower-cost patients. Multiple logistic regression was used to assess the relationship between patient characteristics and being a high-cost sarcoidosis patient. A total of 7,173 sarcoidosis patients met the selection criteria. The 20% of patients classified as high-cost patients accounted for approximately 72% of the total health care costs in the 12-month follow-up period. Compared with lower-cost patients, high-cost patients were slightly older (50.6 vs. 49.1 years) and had a higher comorbidity burden at baseline (Charlson Comorbidity Index = 1.8 vs. 0.7). Mean annual total health care cost for high-cost sarcoidosis patients was 10 times that of their lower-cost counterparts ($73,345 vs. $7,073). Mean annual health care cost was $119,878 for patients in the 95th-99th percentile and $375,436 for patients in the top 1% of spend. High-cost patients had greater medical resource use and costs across all places of service (i.e., inpatient

    2012-01-01

    Sarcoidosis is a granulomatous inflammatory disorder of unclear etiology, which is known to affect multiple organ systems including the lungs, heart, skin, central nervous system, and eyes, among others. For this reason, sarcoidosis represents a systemic medical disorder that is clinically relevant to multiple medical sub-specialties. Despite extensive research, the etiology of sarcoidosis has yet to be elucidated, although most evidence supports that the pathogenetic mechanism of sarcoidosis is an aberrant immune response, driven by an unidentified antigen (or antigens) in genetically susceptible individuals. Multiple candidate etiologic agents, including microbial organisms and environmental agents, have been investigated, but study results are inconclusive. In this review, we describe the known histologic and immunologic features of sarcoidosis and discuss the evidence supporting a role for infectious processes in the pathogenesis of sarcoidosis.

This review will discuss and illustrate the range of pulmonary manifestations on high-resolution computed tomography and chest radiography, concentrating on atypical features and examples of sarcoidosis mimicking other lung diseases. All included cases have been histologically confirmed. Such variable imaging appearances should alert the radiologist to consider sarcoidosis as a differential diagnosis in the context of interstitial lung disease.

    Full Text Available Actinic granuloma is an uncommon granulomatous disease, characterized by annular erythematous plaque with central clearing predominately located on sun-damaged skin. The pathogenesis is not well understood, ultraviolet radiation is recognized as precipitating factor. We report a case of a 52-year-old woman who presented with asymptomatic annular erythematous plaques on the forehead and both cheeks persisting for 2 years. The clinical presentation and histopathologic findings support the diagnosis of actinic granuloma. During that period of time, she also developed focal segmental glomerulosclerosis. The association between actinic granuloma and focal segmental glomerulosclerosis needs to be clarified by further studies.

    The treatment of sarcoidosis is not standardized. Because sarcoidosis may never cause significant symptoms or organ dysfunction, treatment is not mandatory. When treatment is indicated, oral corticosteroids are usually recommended because they are highly likely to be effective in a relative short period of time. However, because sarcoidosis is often a chronic condition, long-term treatment with corticosteroids may cause significant toxicity. Therefore, corticosteroid sparing agents are often indicated in patients requiring chronic therapy. This review outlines the indications for treatment, corticosteroid treatment, and corticosteroid sparing treatments for sarcoidosis. PMID:23596348

    Tuberculosis remains a major human health threat that infects one in three individuals worldwide. Infection with Mycobacterium tuberculosis is a standoff between host and bacteria in the formation of a granuloma. This review will introduce a variety of bacterial and host factors that impact individual granuloma fates. The authors describe advances in the development of in vitro granuloma models, current evidence surrounding infection and granuloma development, and the applicability of existing in vitro models in the study of human disease. In vitro models of infection help improve our understanding of pathophysiology and allow for the discovery of other potential models of study.

    The granuloma is the defining feature of the host response to infection with Mycobacterium tuberculosis (Mtb). Despite knowing of its existence for centuries, much remains unclear regarding the host and bacterial factors that contribute to granuloma formation, heterogeneity of presentation, and the forces at play within. Mtb is highly adapted to life within the granuloma and employs many unique strategies to both create a niche within the host as well as survive the stresses imposed upon it. Adding to the complexity of the granuloma is the vast range of pathology observed, often within the same individual. Here, we explore some of the many ways in which Mtb crafts the immune response to its liking and builds a variety of granuloma features that contribute to its survival. We also consider the multitude of ways that Mtb is adapted to life in the granuloma and how variability in the deployment of these strategies may result in different fates for both the bacterium and the host. It is through better understanding of these complex interactions that we may begin to strategize novel approaches for tuberculosis treatments.

  7. Extrapulmonary sites of radiogallium accumulation in sarcoidosis

    In an effort to detect extrapulmonary sites of radiogallium accumulation in cases of sarcoidosis, 145 separate Ga-67 citrate studies of 114 patients with biopsy-proven sarcoidosis were examined. The most characteristic extrapulmonary radiogallium uptake pattern was the panda sign in 47 patients (41%). The most common site of prominent extrapulmonary radiogallium uptake was the lacrimal glands in 101 patients (88%). Second most common was activity in one or more superficial lymph node regions such as the cervical, axillary, femoral, or inguinal in 19 patients (17%). Other extrapulmonary sites included breast uptake in 6 out of 80 women (8%), prominent splenic and nasal uptake in 9 (8%) patients, periportal accumulation in 7 (6%), and cutaneous/subcutaneous activity in 4 (4%). Because many of these individuals were receiving corticosteroids, the natural (untreated) prevalence of extrapulmonary findings may be even higher. Although the sensitivity and specificity of extrapulmonary radiogallium accumulation has still to be determined, many of the sites may be accessible to biopsy both for diagnostic purposes and to follow the effects of medications. It is therefore suggested that whole-body imaging be performed when radiogallium is administered to patients with suspected or known sarcoidosis.

    TNF blockers are widely used to treat inflammatory rheumatic diseases and also in the treatment of extrapulmonary sarcoidosis. TNFα plays a major role in the development and persistence of sarcoid granulomata. However, recent studies have reported the involvement of anti-TNF therapies in the development of granulomatosis associated with the clinical and radiological features of sarcoidosis. A 54-years-old man with ankylosing spondylitis was treated with etanercept for two years. He was admitted with symptoms of bronchitis associated with radiological evidence of bilateral pulmonary nodules and a right upper lobe infiltrate. Anti-TNF therapy was stopped even though the patient had received 3 months of prophylactic treatment with rifampicin and isoniazid before starting etanercept. Bronchoalveolar lavage excluded infection, particularly tuberculosis. The chest CT-scan showed bilateral pulmonary nodules with peribronchovascular micronodules and enlarged mediastinal lymph nodes. Surgical lung biopsy was performed and revealed non-caseating granulomata. All the data were consistent with a diagnosis of pulmonary sarcoidosis. The patient remained symptomatic despite discontinuation of etanercept for ten months. Corticosteroids were then introduced, leading to a clinical, functional and radiological improvement. This case report underlines the importance of studying the pulmonary complications of TNF blockers. The first priority is to exclude tuberculosis but a diagnosis of sarcoid-like granulomatosis has to be considered. Twenty-three cases have been described in the literature to date.

    A 35-year-old man presented with a 7-year history of gradually enlarging plaques on his face and trunk. The first lesions had developed on both sides of the forehead and the left cheekbone (Figure 1). Four years later similar lesions appeared on his neck and back. He presented a histologic report of a biopsy specimen from a facial plaque performed 5 years earlier that was diagnostic for granuloma faciale. He had different treatments such as topical steroids and cryotherapy without improvement. The appearance of new lesions on his trunk and the gradual enlarging of the old lesions convinced the patient to seek further treatment. Physical examination revealed dusky, violaceous plaques and papules, 0.5 to 2 cm, well-circumscribed, slightly elevated, and located on the face and trunk, with mild pruritus (Figure 1 and Figure 2). Laboratory investigations, including complete blood cell count, VDRL test, antinuclear antibody test, biochemical parameters, and chest x-ray, did not reveal any abnormalities. A skin biopsy taken from the upper part of the back showed similar features to the facial lesion, detected 5 years before, revealing a dense, polymorphous infiltrate involving mid and deep dermis and displaying a diffuse and perivascular pattern (Figure 3A). A narrow grenz zone of normal collagen was consistently observed between dermal infiltrate and epidermis as well as around the pilosebaceous follicles (Figure 3A). The infiltrate mainly consisted of eosinophils and lymphocytes, but neutrophils (often displaying leukocytoclasis), macrophages, and plasma cells were also present (Figures 3B, 3C). Some mast cells were also identified by staining with toluidine blue (Figure 3D). Perivascular infiltrates were often seen, sometimes penetrating vessel walls and in association with leukocytoclasis. Hyalinization of vessel walls, extravasation of red blood cells around capillaries, and nuclear dust were also noted. The epidermis did not show any remarkable change except for

    Introduction. Sarcoidosis, which is a chronic inflammatory granulomatous disease, can mimic different rheumatologic diseases including connective tissue diseases. Antinuclear antibodies are the markers used for connective tissue diseases. Aim. To determine antinuclear antibody frequency and any possible correlation with clinical and laboratory data in sarcoidosis patients. Material and Method. Forty-two sarcoidosis patients, 45 rheumatoid arthritis patients, and 45 healthy volunteers who were followed up in rheumatology outpatient clinic were included in this study. Demographic, clinical, serological, and radiological data of all patients were recorded. Antinuclear antibodies were determined with indirect immunofluorescent method and 1/100 titration was accepted as positive. The cases that were ANA positive were evaluated with immunoblot method. Results. Average age of the 42 patients (10 males) with sarcoidosis was 45.2 (20-70 years), and average disease duration was 3.5 years. ANA positivity was detected in 12 (28.5%) patients with sarcoidosis (1/100 in 10 patients, 1/320 in two patients), in 19 of RA patients (42.2%), and in two of healthy volunteers in low titer (P syndrome and scleroderma diagnosis, respectively. Discussion. The prevalence of ANA in patients with sarcoidosis was found to be significantly higher than healthy control group and lower than RA patients. This result shows that ANA may have an important role in the pathogenesis of sarcoidosis and also could be important in revealing the overlap syndromes of sarcoidosis-connective tissue diseases. Further studies with larger series are necessary in this subject.

    Tuberculosis and sarcoidosis share similar histopathological findings. An aetiological connection between these diseases has been discussed. We report a case of pulmonary sarcoidosis, which occurred shortly after an isoniazid (INH)-resistant spinal tuberculosis was diagnosed which was suspected to be a miliary tuberculosis. This report illustrates the need to sensitise clinicians to two possible important causes of lung parenchyma alterations under tuberculostatic therapy.

    Abstract The association between cancer and sarcoidosis is controversial. Some epidemiological studies show an increase of the incidence of cancer in patients with sarcoidosis but only few cases of sarcoidosis following cancer treatment have been reported. We conducted a retrospective case study from internal medicine and oncology departments for patients presenting sarcoidosis after solid cancer treatment. We also performed a literature review to search for patients who developed sarcoidosis after solid cancer. We describe the clinical, biological, and radiological characteristics and outcome of these patients. Twelve patients were included in our study. Various cancers were observed with a predominance of breast cancer. Development of sarcoidosis appeared in the 3 years following cancer and was asymptomatic in half of the patients. The disease was frequently identified after a follow-up positron emission tomography computerized tomography evaluation. Various manifestations were observed but all patients presented lymph node involvement. Half of the patients required systemic therapy. With a median follow-up of 73 months, no patient developed cancer relapse. Review of the literature identified 61 other patients for which the characteristics of both solid cancer and sarcoidosis were similar to those observed in our series. This report demonstrates that sarcoidosis must be considered in the differential diagnosis of patients with a history of malignancy who have developed lymphadenopathy or other lesions on positron emission tomography computerized tomography. Histological confirmation of cancer relapse is mandatory in order to avoid unjustified treatments. This association should be consider as a protective factor against cancer relapse. PMID:26181571

    Sarcoidosis is a multisystem, granulomatous disease that most often affects the lungs. The clinical course is highly variable; many patients undergo spontaneous remission, but up to a third of patients progresses to a chronic disease course. The development of pulmonary fibrosis (PF) in a subset of patients with chronic disease has a negative impact on morbidity and mortality. While sarcoidosis-associated PF can be progressive, it is often referred to as “burnt out” disease, a designation reflecting inactive granulomatous inflammation. The immune mechanisms of sarcoidosis-associated PF are not well understood. It is not clear if fibrotic processes are active from the onset of sarcoidosis in predisposed individuals, or whether a profibrotic state develops as a response to ongoing inflammation. Transforming growth factor β (TGF-β) is an important profibrotic cytokine, and in sarcoidosis, distinct genotypes of TGF-β have been identified in those with PF. The overall cytokine profile in sarcoidosis-associated PF has not been well characterized, although a transition from a T helper 1 to a T helper 2 signature has been proposed. Macrophages have important regulatory interactions with fibroblasts, and the role of alveolar macrophages in sarcoidosis-associated PF is a compelling target for further study. Elucidating the natural history of sarcoidosis-associated PF will inform our understanding of the fundamental derangements, and will enhance prognostication and the development of therapeutic strategies.

    Sarcoidosis is a granulomatous disease which can affect multiple organ systems. Clinical and radiologic manifestations depend on the organ system involved and the chronicity of disease. Nail involvement in sarcoidosis is rare, but is clinically relevant as it indicates chronic systemic disease. Nail abnormalities can be identified radiographically, and when seen in patients with known or suspected sarcoidosis, should prompt careful evaluation of the underlying bone for osseous involvement. We describe a case of sarcoidosis with radiographic findings in the nails and distal phalangeal tufts, which were indicative of nail and osseous sarcoid involvement and strongly supported the presence of chronic systemic disease. Although the nail findings resolved clinically and on radiographs after treatment, the osseous findings showed only minimal improvement. To our knowledge, the radiographic findings of nail sarcoidosis have not been previously addressed in the literature. (orig.)

  20. Rapidly Progressive Atrioventricular Block in a Patient with Sarcoidosis

    Full Text Available Cardiac sarcoidosis is a major cause of death in patients with systemic sarcoidosis. Cardiac manifestations are seen in 2.3% of the patients. Atrioventricular (AV block is one of the common manifestations of cardiac sarcoidosis. Other presentations of cardiac involvement include congestive heart failure, ventricular arrhythmias, and sudden cardiac death. The presence of AV block in young patients should raise the suspicion of sarcoidosis. AV block may be the only manifestation and patients may not have clinical evidence of pulmonary involvement. Here we describe a young male presented with exercise induced AV block rapidly progressing to complete heart block with recurrent syncope needing urgent pacemaker implantation. Factors that suggested an infiltrative process included his young age, rapidly progressive conduction abnormalities in the ECG in the absence of coronary disease, and previous history of cutaneous sarcoidosis.

  1. Recognition of distinctive patterns of gallium-67 distribution in sarcoidosis

    1990-12-01

    Assessment of gallium-67 ({sup 67}Ga) uptake in the salivary and lacrimal glands and intrathoracic lymph nodes was made in 605 consecutive patients including 65 with sarcoidosis. A distinctive intrathoracic lymph node {sup 67}Ga uptake pattern, resembling the Greek letter lambda, was observed only in sarcoidosis (72%). Symmetrical lacrimal gland and parotid gland {sup 67}Ga uptake (panda appearance) was noted in 79% of sarcoidosis patients. A simultaneous lambda and panda pattern (62%) or a panda appearance with radiographic bilateral, symmetrical, hilar lymphadenopathy (6%) was present only in sarcoidosis patients. The presence of either of these patterns was particularly prevalent in roentgen Stages I (80%) or II (74%). We conclude that simultaneous (a) lambda and panda images, or (b) a panda image with bilateral symmetrical hilar lymphadenopathy on chest X-ray represent distinctive patterns which are highly specific for sarcoidosis, and may obviate the need for invasive diagnostic procedures.

    Contact ulcer and granuloma is an etiologically multifactorial chronic inflammatory disease of the larynx. Besides mechanical laryngeal factors, gastrointestinal and psychosomatic aspects of pathogenesis have been suggested. 51 patients suffering from contact ulcer or granuloma underwent laryngologic and phoniatric examination. In addition, a questionnaire asking for symptoms and habits (smoking, alcohol) was completed by each patient. Subsequent to completing the treatment course, the patients were re-examined. Each patient was examined several times and the success of 6 therapeutic strategies was compared. 49 patients were male and almost 70% complained of private or professional stress. Since only 8% were smokers, smoking habits do not play a pathogenetic role. Drinking habits are also not a significant factor. A striking therapeutic result observed by us was complete remission in more than 80% of patients who had received an acid-inhibiting agent as monotherapy. The remission was higher in this group than in patients treated by logopedic therapy. In case of carcinophobia or if cancer could not be excluded by laryngoscopy and stroboscopy, granulomas were removed surgically. More than 90% of these patients suffered from recurrence unless voice therapy was directly performed. On the other hand, antacid therapy yielded excellent results in patients suffering from recurrent granuloma or ulcer after surgery. We conclude that peptic diseases of stomach and oesophagus play an important role in the pathogenesis of contact ulcer and granuloma and recommend routine interviews and internal examination of patients. Antacid therapy should be firmly installed in the therapeutic strategy against contact ulcer.

    To determine the specific high-resolution CT features of sarcoidosis in which the observed pattern is predominantly pseudoalveolar. We retrospectively reviewed the HRCT findings in 15 cases in which chest radiography demonstrated pseudoalveolar consolidation. In all 15, sarcoidosis was pathologically proven. The distribution and characterization of the following CT features was meticulously scrutinized: distribution and characterization of pseudoalveolar lesions, air-bronchograms, micronodules, thickening of bronchovascular bundles and interlobular septa, lung distortion, ground-glass opacities and combined hilar and mediastinal lymphadenopathy. Follow-up CT scans were available in three cases after corticosteroid administration. Between one and 12 (mean, 5.6) pseudoalveolar lesions appeared as dense homogeneous or inhomogeneous opacities 1-4.5 cm in diameter and with an irregular margin located either at the lung periphery adjacent to the pleural surface or along the bronchovascular bundles, with mainly bilateral distribution (n=14, 93%). An air-bronchogram was observed in ten cases. Micronodules were observed at the periphery of the lesion or surrounding lung, which along with a thickened bronchovascular bundle was a consistent feature in all cases. Additional CT features included hilar and mediastinal lymphadenopathy (n=14, 93%), thickened interlobular septa (n=12, 80%), and ground-glass opacity (n=10, 67%). Lung distortion was noted in only one case (7%). After steroid administration pseudoalveolar lesions decreased in number and size in all three cases in which follow-up CT was available. The consistent HRCT features of pseudoalveolar sarcoidosis are bilateral multifocal dense homogenous or inhomogenous opacity and an irregular margin located either at the lung periphery adjacent to the pleural surface or along the bronchovascular bundles. Micronodules are present at the periphery of the lesion or surrounding lung. The features are reversible administration.

  5. Radiologic appearance of chronic parapharyngeal Teflon granuloma.

    2010-01-01

    Although Teflon has been used for almost 5 decades to provide tissue augmentation in various surgical indications, including head and neck surgery, its use has significantly declined in the last 2 decades, primarily because of its implication in granuloma formation. Teflon granulomas have been shown to cause false positives on positron emission tomography imaging and have been reported to have a characteristic magnetic resonance imaging (MRI) appearance. We report a patient with a large chronic Teflon granuloma of the parapharyngeal space that caused significant bony erosion of the atlas vertebra. The lesion's MRI signal characteristics were indistinguishable from those of surrounding tissues, while it showed characteristic hyperdensity on computed tomography due to the presence of fluorine atoms within Teflon. As MRI may supersede or replace computed tomography for a number of indications, and as Teflon has been used in large numbers of patients whose records may not always be available, knowledge of these findings has clinical relevance.

  9. The etiologic role of infectious antigens in sarcoidosis pathogenesis

    Science.gov (United States)

    Celada, Lindsay J.; Hawkins, Charlene; Drake, Wonder P.

    2015-01-01

    Sarcoidosis is a granulomatous disease of unknown etiology, characterized by a Th1 immunophenotype, most commonly involving the lung, skin, lymph node and eyes. Molecular and immunologic studies continue to strengthen the association of sarcoidosis with infectious antigens, particularly those derived from Propionibacterium and Mycobacterium species. Independent studies report the presence of microbial nucleic acids and proteins within sarcoidosis specimens. Complementary immunologic studies also support the role of infectious agents in sarcoidosis pathogenesis. Th-1 immune responses directed against mycobacterial virulence factors have been detected within sarcoidosis diagnostic bronchoalveolar lavage (BAL). Th1 and Th17 immune responses against propionibacteria have also been reported. More recently, case reports and clinical trials from Japanese, European and American investigators have emerged regarding the efficacy of antimicrobials against Propionibacterium and Mycobacterium species on pulmonary and cutaneous sarcoidosis. While these clinical investigations are not conclusive, they support increasing efforts to identify novel therapeutics, such as antimicrobials, that will impact the observed increase in sarcoidosis morbidity and mortality.

    In this article we describe a 39-year-old man who presented with non-scarring non-scalp alopecia of his limbs as the initial presentation of sarcoidosis. Alopecia is a rare cutaneous manifestation of sarcoidosis. A literature review has found only one other example of sarcoidosis presenting as non-scarring non-scalp alopecia in an area other than the scalp in a patient who was otherwise asymptomatic. Several reported cases have described scarring alopecia of the scalp, which is the area of skin most commonly affected by sarcoidosis. There has been one documented case of sarcoidosis manifesting as total body non-scarring alopecia in a patient who had systemic symptoms of sarcoidosis. Other cases have presented rare cutaneous manifestations of sarcoidosis but in all these cases several other organ systems have been involved, and the patient has had systemic symptoms on presentation or the cutaneous presentation did not include non-scalp non-scarring alopecia. © 2015 The Australasian College of Dermatologists.

    This study investigates the immunohistochemical expression of vascular endothelial growth factor (VEGF) and CD34 in patients treated for middle ear and mastoid cholesterol granulomas to evaluate the angiogenesis and vascularization of this type of lesion. A correlation between the immunohistochemical data and the radiological and intraoperative evidence of temporal bone marrow invasion and blood source connection was performed to validate this hypothesis. Retrospective study. Immunohistochemical expression of VEGF and CD34 in a group of 16 patients surgically treated for cholesterol granuloma was examined. Middle ear cholesteatomas with normal middle ear mucosa and external auditory canal skin were used as the control groups. The radiological and intraoperative features of cholesterol granulomas were also examined. In endothelial cells, there was an increased expression of angiogenetic growth factor receptors in all the cholesterol granulomas in this study. The quantitative analysis of VEGF showed a mean value of 37.5, whereas the CD34 quantitative analysis gave a mean value of 6.8. Seven patients presented radiological or intraoperative evidence of bone marrow invasion, hematopoietic potentialities, or blood source connections that might support the bleeding theory. In all of these cases there was computed tomography or intraoperative evidence of bone erosion of the middle ear and/or temporal bone structures. The mean values of VEGF and CD34 were 41.1 and 7.7, respectively. High values of VEGF and CD34 are present in patients with cholesterol granulomas. Upregulation of VEGF and CD34 is indicative of a remarkable angiogenesis and a widespread vascular concentration in cholesterol granulomas. 3b.

    To present data on hemodynamic changes during dental extractions in 5 patients with cardiac sarcoidosis, performed with electrocardiogram, heart rate, and blood pressure monitoring throughout the procedures, and to discuss the problems relating to the disease and dental extraction. The medical data for 5 patients, including medical records, physician correspondence, and laboratory data before the treatments, were assessed. Seven dental extractions were then performed while monitoring and recording the hemodynamic conditions. Heart rate, blood pressure, rate pressure products, and electrocardiographic findings were analyzed. Finally, posttreatment evaluations of the general and local conditions of the patients were conducted. All dental extractions were performed in nonactive stable periods, with no remarkable hemodynamic changes or complications, while maintaining a stable hemodynamic state throughout the extraction procedure. All patients received a pretreatment supplement of corticosteroid. Wound healing was similar to that in normal patients under antibiotic prophylaxis against infection originating from the dental extraction wound and the original dental lesion. Pretreatment general evaluation of patients with cardiac sarcoidosis should be performed through various examinations and physician consultation, and a stable hemodynamic change during the surgical procedure should be maintained under any hemodynamic monitors. Corticosteroid supplement and antibiotic coverage are also necessary for safe dental extraction and suitable healing.

    We present a patient with Cushing disease apparently suppressing sarcoidosis, which was unmasked following surgical resection of a pituitary adrenocorticotropin (ACTH)-producing microadenoma. Case report and a short review of the literature published in this area. A 46-year-old Caucasian woman presented with symptoms of hypercortisolism such as progressive weight gain, Cushingoid appearance, proximal myopathy, easy bruising, and amenorrhea. Blood testing including inferior petrosal sinus sampling uncovered an ACTH-producing microadenoma in the right aspect of the anterior pituitary gland for which the patient underwent transphenoidal resection. Maintenance corticosteroid therapy was implemented, and the signs and symptoms of Cushing disease began to resolve. Three months after surgery, multiple erythematous painful nodules developed on the patient's arms. Erythema nodosum (EN) was diagnosed clinically and a suspicion of underlying sarcoidosis was substantiated by lung imaging and elevated plasma interleukin (IL)-2 receptor. One month later, the lesions spontaneously resolved without therapy other than maintenance glucocorticoid replacement. Physicians should be aware that patients undergoing successful treatment of Cushing syndrome may have a flare-up or emergence of a corticosteroid-responsive disease.

    Coexistence of systemic sclerosis (SSc) and sarcoidosis (SA) is rarely reported; 21 cases only were reported in the English medical literature before 2011. It is suggested that low incidence of overlap syndrome of SSc with SA is resulted from different immune mechanisms involved in pathogenesis of the diseases. In SSc patients, a role of Th2 lymphocytes is suggested while in patients with SA such role is attributed to Th1 lymphocytes. The paper presents a 47-year-old woman suffering from SSc for over 6 years. CT scan of the lungs revealed the nodulus of the right lung and enlarged mediastinal lymphatic nodes. Pathologic evaluation of the nodulus provided basis for diagnosis of sarcoidosis. Diagnosis of SSc was based on clinical and capilaroscopic evaluation as well as detection of anti-topoisomerase I antibodies. In the course of the disease, fibrosis of the lung, pulmonary hypertension and cardiac abnormalities with rhythm disturbances were developed. Treatment included cyclophosphamide, mycophenolate mofetil, sildenafil, losartan. Stabilization of the general state of the patient was achieved.

    This paper reports three cases of severe post-stapedectomy granuloma, emphasising the variable presentation of this devastating complication and the challenges of its management. A retrospective review was conducted of three cases of post-stapedectomy granuloma requiring surgical debulking between 2010 and 2015. Clinical symptoms, serial imaging, histopathology and post-operative outcomes were considered. Intra-operatively, extensive granulation tissue with erosion of the otic capsule was found. There was spread along the VIIth and VIIIth cranial nerves to the cochlear nucleus in one patient. Post-operative clinical improvement was demonstrable, corroborated by diminution of contrast enhancement on serial magnetic resonance imaging. Facial nerve function recovered, tinnitus amelioration was variable and some otalgia persisted. Post-operative complications included grade IV facial weakness and late Pseudomonas aeruginosa meningitis, which all resolved. To the authors' knowledge, this paper reports the only case of post-stapedectomy granuloma tracking to the brainstem. Otalgia was present in all our cases, and may be deemed a red flag symptom of progressive bony destruction and otic capsule involvement. Although granuloma remains rare, it should be considered in any patient with worsening otological symptoms following stapes surgery.

    Granulomas are a collection of immune cells considered to be protective in infectious diseases. The in vitro generation of granulomas is an interesting substitution to invasive approaches of granuloma study. The monitoring of immune response through the determination of in vitro granuloma formation in patients with severe sepsis may be critical to individualize treatments. We compared the in vitro generation of granulomas by co-culturing circulating mononuclear cells from 19 patients with severe sepsis, 9 patients cured from Q fever and 12 healthy subjects as controls, and Sepharose beads coated either with BCG or Coxiella burnetii extracts to analyze both immune and innate granulomas, respectively. We showed that the great majority of patients with severe sepsis were unable to form granulomas in response to BCG and C. burnetii extracts whereas more than 80% of healthy controls and patients cured from Q fever formed granulomas. We also found that monocytopenia and defective production of tumor necrosis factor were associated with reduced formation of granulomas in patients with severe sepsis even if TNF did not seem to be involved in the defective granuloma formation. Taken together, these results suggest that the deficiency of granuloma formation may be a measurement of altered recruitment and activation of monocytes and lymphocytes in patients with severe sepsis.

    The uptake of gallium-67 by pulmonary sarcoidosis was noted by Langhammer et al. in 1972 and by McKusick et al. in 1973. Heshiki et al. studied the application of this procedure in the diagnosis of sarcoidosis and concluded that although gallium-67 uptake in lungs and hilar regions correlated poorly with clinical activity, its measurement might prove useful in the diagnosis of sarcoidosis and in the measurement of response to therapy. We have undertaken to evaluate further the clinical usefulness of this technique. Thirty-six patients, 27 of whom had sarcoidosis, were given intravenous injections of 3 ml of commercially obtained (/sup 67/Ga) citrate. None were receiving corticosteroid therapy at the time of the initial study. Three days later simultaneous anterior and posterior scans of the thorax and the upper abdomen were performed in the supine position. 1 table.

  15. Diffuse bronchiectasis as the primary manifestation of endobronchial sarcoidosis

    Directory of Open Access Journals (Sweden)

    2017-01-01

    Full Text Available Sarcoidosis is an idiopathic disease that most commonly involves the lungs and is characterized by granulomatous inflammation. Bronchiectasis is one pulmonary manifestation of sarcoidosis, although it is almost always observed as traction bronchiectasis in the setting of fibrotic lung disease. A 50-year-old woman was evaluated for chronic cough and bronchiectasis with a small amount of peripheral upper lobe honeycombing and no significant pulmonary fibrosis or lymphadenopathy. After an extensive laboratory and imaging evaluation did not identify a cause of her bronchiectasis, bronchoscopy was performed to assess for primary ciliary dyskinesia and revealed a diffuse cobblestone appearance of the airway mucosa. Endobronchial biopsies and lymphocyte subset analysis of bronchoalveolar lavage fluid were consistent with a diagnosis of sarcoidosis. We believe endobronchial sarcoidosis should be included in the differential diagnosis of patients presenting with bronchiectasis.

  16. The Prevalence of Antinuclear Antibodies in Patients with Sarcoidosis

    2014-01-01

    Full Text Available Introduction. Sarcoidosis, which is a chronic inflammatory granulomatous disease, can mimic different rheumatologic diseases including connective tissue diseases. Antinuclear antibodies are the markers used for connective tissue diseases. Aim. To determine antinuclear antibody frequency and any possible correlation with clinical and laboratory data in sarcoidosis patients. Material and Method. Forty-two sarcoidosis patients, 45 rheumatoid arthritis patients, and 45 healthy volunteers who were followed up in rheumatology outpatient clinic were included in this study. Demographic, clinical, serological, and radiological data of all patients were recorded. Antinuclear antibodies were determined with indirect immunofluorescent method and 1/100 titration was accepted as positive. The cases that were ANA positive were evaluated with immunoblot method. Results. Average age of the 42 patients (10 males with sarcoidosis was 45.2 (20–70 years, and average disease duration was 3.5 years. ANA positivity was detected in 12 (28.5% patients with sarcoidosis (1/100 in 10 patients, 1/320 in two patients, in 19 of RA patients (42.2%, and in two of healthy volunteers in low titer (P<0.001. In the subgroup analysis made by immunblot test, one patient had anticentromere antibody, one had anti-Ro antibody, one had anti-Scl-70 antibody, one had anti-dsDNA antibody, and eight patients were negative. The two patients who had anticentromere and anti-Scl-70 antibodies had also Sjögren’s syndrome and scleroderma diagnosis, respectively. Discussion. The prevalence of ANA in patients with sarcoidosis was found to be significantly higher than healthy control group and lower than RA patients. This result shows that ANA may have an important role in the pathogenesis of sarcoidosis and also could be important in revealing the overlap syndromes of sarcoidosis-connective tissue diseases. Further studies with larger series are necessary in this subject.

  17. Racial Difference in Sarcoidosis Mortality in the United States

    2015-01-01

    BACKGROUND: The clinical presentation and outcome of sarcoidosis varies by race. However, the race difference in mortality outcome remains largely unknown. METHODS: We studied mortality related to sarcoidosis from 1999 through 2010 by examining data on multiple causes of death from the National Center for Health Statistics. We compared the comorbid conditions between sarcoidosis-related deaths with deaths caused by car accidents (previously healthy control subjects) and rheumatoid arthritis (chronic disease control subjects) in both African Americans and Caucasians. RESULTS: From 1999 through 2010, sarcoidosis was reported as an immediate cause of death in 10,348 people in the United States with a combined overall mean age-adjusted mortality rate of 2.8 per 1 million person-years. Of these, 6,285 were African American and 3,984 Caucasian. The age-adjusted mortality rate for African Americans was 12 times higher than for Caucasians. African Americans died at an earlier age than Caucasians. African Americans living in the District of Columbia and North Carolina and Caucasians living in Vermont had higher mortality rates. Although the total sarcoidosis age-adjusted mortality rate had not changed over the 12 year period studied, this rate increased for Caucasians (R = 0.747, P = .005) but not for African Americans. Compared with the control groups, pulmonary hypertension was significantly more common in individuals with sarcoidosis. CONCLUSIONS: This nationwide population-based study exposes a significant difference in ethnicity and sex among people dying of sarcoidosis in the United States. Pulmonary hypertension investigation should be considered in all patients with sarcoidosis, especially African Americans. PMID:25188873

    Hepatic sarcoidosis is usually asymptomatic but rarely leads to adverse liver-related outcome. Co-existence of viral hepatitis and hepatic sarcoidosis is a rare, but recognised phenomenon. Obtaining a balance between immune suppression and anti-viral therapy may be problematic. Immunosuppression in the presence of viral hepatitis can lead to rapid deterioration of liver disease. Similarly, anti-viral therapy may exacerbate granulomatous hepatitis. Here we present two cases of viral hepatitis ...

    Many studies include elevated activity of angiotensin-converting enzyme (ACE) in serum in sarcoidosis and in ocular sarcoidosis as well, but there are only a few analyzing ACE activities in aqueous humor. The aim of this study is to illuminate the diagnostic value of ACE in aqueous humor in patients with ocular sarcoidosis. We analyzed twenty patients with ocular sarcoidosis and 18 patients with nonocular involvement. All patients have biopsy-positive sarcoidosis of the lungs and/or mediastinal lymph nodes. Blood samples for ACE serum levels were obtained from all patients. Aqueous humor samples were taken by paracentesis with a 25-gauge needle in local anesthesia. With appropriate statistical tests, we compared ACE activity in serum and aqueous humor in patients with and without ocular sarcoidosis. The majority of our patients with ocular sarcoidosis were female (12/20), also in the group with systemic sarcoidosis and without ocular involvement (12/6). Mean age of the whole analyzed group of sarcoidosis patients was 45 ± 6 years. There is no statistically significant difference in ACE activity in serum between two groups of patients (with and without ocular sarcoidosis). There is statistically significant difference in ACE activity in aqueous humor among patients with ocular and nonocular sarcoidosis. ACE activity in aqueous humor is significantly higher in patients with ocular sarcoidosis. Increased ACE activity in aqueous humor can point to a diagnosis of ocular sarcoidosis, without the need for ocular biopsy.

    2017-11-01

    Sarcoidosis is a multisystemic inflammatory disease that commonly affects the eye and less often the neuro-ophthalmic pathways. The manifestations can be quite variable but can have characteristic signs and clinical features. This review provides a comprehensive overview of the various ocular and neuro-ophthalmic manifestations of sarcoidosis, emerging diagnostic measures and approach to treatment. Particular focus is given to recent advances in diagnostic approach and available treatment options. Laboratory investigations, chest and nuclear medicine imaging remain important techniques for helping to diagnose sarcoidosis. Recent evidence suggests a role for aqueous humor analysis in the diagnosis of ocular sarcoidosis. Characteristic neuroimaging may help differentiate neurosarcoidosis from other causes. The role of blind conjunctival biopsy for suspected neurosarcoidosis is discussed. The emerging role and use of biologics is delineated for the treatment of both ocular and neuro-ophthalmic sarcoidosis. Sarcoidosis can affect any part of the visual system: the most common ocular manifestation is uveitis and the most common neuro-ophthalmic manifestation is optic neuropathy. Although diagnosis remains challenging, recent advancements in diagnosis are promising. Emerging biologics with particular efficacy for ocular and neuro-ophthalmic disease provide expanding treatment options for sight-threatening disease.

    Sarcoidosis is a systemic disease characterized by noncaseating granulomatous inflammation with tremendous clinical heterogeneity and uncertain pathobiology and lacking in clinically useful biomarkers. The Genomic Research in Alpha-1 Antitrypsin Deficiency and Sarcoidosis (GRADS) study is an observational cohort study designed to explore the role of the lung microbiome and genome in these two diseases. This article describes the design and rationale for the GRADS study sarcoidosis protocol. The study addresses the hypothesis that distinct patterns in the lung microbiome are characteristic of sarcoidosis phenotypes and are reflected in changes in systemic inflammatory responses as measured by peripheral blood changes in gene transcription. The goal is to enroll 400 participants, with a minimum of 35 in each of 9 clinical phenotype subgroups prioritized by their clinical relevance to understanding of the pathobiology and clinical heterogeneity of sarcoidosis. Participants with a confirmed diagnosis of sarcoidosis undergo a baseline visit with self-administered questionnaires, chest computed tomography, pulmonary function tests, and blood and urine testing. A research or clinical bronchoscopy with a research bronchoalveolar lavage will be performed to obtain samples for genomic and microbiome analyses. Comparisons will be made by blood genomic analysis and with clinical phenotypic variables. A 6-month follow-up visit is planned to assess each participant’s clinical course. By the use of an integrative approach to the analysis of the microbiome and genome in selected clinical phenotypes, the GRADS study is powerfully positioned to inform and direct studies on the pathobiology of sarcoidosis, identify diagnostic or prognostic biomarkers, and provide novel molecular phenotypes that could lead to improved personalized approaches to therapy for sarcoidosis.

  5. Chronic Schistosome Infection Leads to Modulation of Granuloma Formation and Systemic Immune Suppression

    Directory of Open Access Journals (Sweden)

    Steven K. Lundy

    2013-02-01

    Full Text Available Schistosome worms have been infecting humans for millennia, but it is only in the last half century that we have begun to understand the complexities of this inter-relationship. As our sophistication about the inner workings of every aspect of the immune system has increased, it has also become obvious that schistosome infections have broad ranging effects on nearly all of the innate and adaptive immune response mechanisms. Selective pressures on both the worms and their hosts, has no doubt led to co-evolution of protective mechanisms, particularly those that favor granuloma formation around schistosome eggs and immune suppression during chronic infection. The immune modulatory effects that chronic schistosome infection and egg deposition elicit have been intensely studied, not only because of their major implications to public health issues, but also due to the emerging evidence that schistosome infection may protect humans from severe allergies and autoimmunity. Mouse models of schistosome infection have been extremely valuable for studying immune modulation and regulation, and in the discovery of novel aspects of immunity. A progression of immune reactions occurs during granuloma formation ranging from innate inflammation, to activation of each branch of adaptive immune response, and culminating in systemic immune suppression and granuloma fibrosis. Although molecular factors from schistosome eggs have been identified as mediators of immune modulation and suppressive functions of T and B cells, much work is still needed to define the mechanisms of the immune alteration and determine whether therapies for asthma or autoimmunity could be developed from these pathways.

    2013-01-01

    Background Leprosy is a contagious and chronic systemic granulomatous disease caused by Mycobacterium leprae. In the pathogenesis of leprosy, granulomas play a key role, however, the mechanisms of the formation and maintenance of M. leprae granulomas are still not clearly understood. Methods To better understand the molecular physiology of M. leprae granulomas and the interaction between the bacilli and human host cells, we developed an in vitro model of human granulomas, which mimicked the in vivo granulomas of leprosy. Macrophages were differentiated from human monocytes, and infected with M. leprae, and then cultured with autologous human peripheral blood mononuclear cells (PBMCs). Results Robust granuloma-like aggregates were obtained only when the M. leprae infected macrophages were co-cultured with PBMCs. Histological examination showed M. leprae within the cytoplasmic center of the multinucleated giant cells, and these bacilli were metabolically active. Macrophages of both M1 and M2 types co-existed in the granuloma like aggregates. There was a strong relationship between the formation of granulomas and changes in the expression levels of cell surface antigens on macrophages, cytokine production and the macrophage polarization. The viability of M. leprae isolated from granulomas indicated that the formation of host cell aggregates benefited the host, but the bacilli also remained metabolically active. Conclusions A simple in vitro model of human M. leprae granulomas was established using human monocyte-derived macrophages and PBMCs. This system may be useful to unravel the mechanisms of disease progression, and subsequently develop methods to control leprosy. PMID:23782413

    Conclusion: Co-existence of sarcoidosis, CD and APS is extremely rare. APS should be recognized as an accompanying disorder of sarcoidosis and antiphospholipids measured especially when there is a history of thrombosis or miscarriages. CD should not be overlooked in association to sarcoidosis, given the shared immunological and genetic background, even in the absence of a typical presentation of the disease.

    The association between sarcoidosis and autoimmune comorbidities has been reported, however, it has seldom been confirmed by a large nationwide study. Our study aimed to clarify the association between sarcoidosis and autoimmune comorbidities in the Taiwanese. A total of 1237 patients with sarcoidosis and 4948 age- and sex-matched control subjects were selected from the National Health Insurance Research Database of Taiwan from 1997 to 2010. Multiple logistic regressions were performed to calculate the odds of comorbidities between the two groups. The prevalence of sarcoidosis was 2.17/100 000 individuals in Taiwan. Sarcoidosis patients tended to run a higher risk of autoimmune comorbidities than the control group (17.6% vs 9.4%, P sarcoidosis. The sex-stratified analyses were carried out to demonstrate a significant association of sarcoidosis with ankylosing spondylitis in both sexes, but with autoimmune thyroid disease in male patients and with Sjögren's syndrome female patients, respectively. Besides, the diagnosis of the autoimmune comorbidities strongly associated with sarcoidosis tended to be established after that of sarcoidosis. This study demonstrated that patients with sarcoidosis tended to have autoimmune thyroid disease, Sjögren's syndrome and ankylosing spondylitis, and the diagnosis of sarcoidosis usually preceded that of associated comorbidities. Clinicians should be alert to autoimmune comorbidities in patients with sarcoidosis. © 2016 Japanese Dermatological Association.

    Patients with pygenic granuloma following burns (PGB) presents dramatic clinical features which are different from those with classic pyogenic granuloma. This review aims to discuss whether pyogenic granuloma following burns (PGB) need excision or not. Using the PubMed, EMBASE, Cochrane Library and web of science databases. All articles which discussed diagnosis and treatment of pyogenic granuloma following burns with histological results were included from 1978 to 2013. Reports from meetings were not included. Only articles published in English were included. Twenty one articles excluded from a total of 32 studies. One study was excluded from the 11 descriptive studies because of typical histological results. The rest, 10 studies were case reports. Only one article was published in French, whose abstract was published in French and English. Patients with PGB presented six distinctive clinical features. First, all the patients had burns initially. The second, PGB acutely erupted between 1 and 4 weeks in patients' burned area, which may be infected by bacteria, fungus and virus. The fourth, PGB can be classified into proliferative and shrivelling stages. The fifth, three hisiological characteristics including hyperkeratosis or acanthosis, numerous newly formed proliferative vascular, edematous stroma with infiltration by plasma cells and lymphocytes. Finally, recurrence, 6 out of 16 patients with PGB involuted spontaneously with no recurrence. Three out of 16 patients were conservatively managed with no recurrence, neither patients (5) who had surgery and 2 patients treated with electro coagulation had recurrence. PGB lesions are benign based on clinical features and histological examinations. The clinical process of PGB could be divided into proliferative and shrivelling stages. Conservative treatment including wound management and antibiotic could be chosen firstly, especially when large PGBs are on the face or other important area of one's body. When conservative

    Sarcoidosis is a granulomatous disorder of unknown etiology. Infection, genetic factors, autoimmunity and an aberrant innate immune system have been explored as potential causes of sarcoidosis. The etiology of sarcoidosis remains unknown, and it is thought that it might be caused by an infectious agent in a genetically predisposed, susceptible host. Inflammation results from recognition of evolutionarily conserved structures of pathogens (Pathogen-associated molecular patterns, PAMPs) and/or from reaction to tissue damage associated patterns (DAMPs) through recognition by a limited number of germ line-encoded pattern recognition receptors (PRRs). Due to the similar clinical and histopathological picture of sarcoidosis and tuberculosis, Mycobacterium tuberculosis antigens such early secreted antigen (ESAT-6), heat shock proteins (Mtb-HSP), catalase-peroxidase (katG) enzyme and superoxide dismutase A peptide (sodA) have been often considered as factors in the etiopathogenesis of sarcoidosis. Potential non-TB-associated PAMPs include lipopolysaccharide (LPS) from the outer membrane of Gram-negative bacteria, peptidoglycan, lipoteichoic acid, bacterial DNA, viral DNA/RNA, chitin, flagellin, leucine-rich repeats (LRR), mannans in the yeast cell wall, and microbial HSPs. Furthermore, exogenous non-organic antigens such as metals, silica, pigments with/without aluminum in tattoos, pesticides, and pollen have been evoked as potential causes of sarcoidosis. Exposure of the airways to diverse infectious and non-infectious agents may be important in the pathogenesis of sarcoidosis. The current review provides and update on the role of PPRs and DAMPs in the pathogenesis of sarcoidsis. Copyright © 2017 Elsevier B.V. All rights reserved.

    The chronic granulomatous inflammation of sarcoidosis has been hypothesized to depend on the CD4+ T-helper lymphocyte. HIV infection, which depletes these cells, has been reported to attenuate the manifestations of sarcoidosis. We asked whether the development of symptomatic sarcoidosis in the context of preexisting HIV infection was dependent on the CD4+ lymphocyte count. We performed a retrospective standardized chart review of all patients who developed granulomatous inflammation following HIV infection at an urban academic referral center. We identified seven patients with sarcoidosis within this cohort and compared their CD4+ lymphocyte count to that in a cohort of 16 patients in whom similar granulomatous inflammation was found but who did not have sarcoidosis. We then compared our cases to all reported cases using a systematic literature review. The CD4+ lymphocyte count was > 200 cells/ microL in all of our patients with HIV infection when they developed subsequent sarcoidosis. In contrast, specific etiologies for granulomatous inflammation were found in all 10 HIV-infected patients who presented with granulomatous inflammation and a CD4+ lymphocyte count of 200 cells/ microL. We conclude that the development of the chronic granulomatous inflammation of sarcoidosis appears to depend on the preservation or restoration of the peripheral CD4+ lymphocyte count and that in most cases the CD4+ lymphocyte count exceeds 200 cells/ microL. Furthermore, alternative specific etiologies of granulomatous inflammation are generally identifiable in HIV-infected patients with peripheral CD4+ lymphocyte counts of < 200 cells/ microL.

    In 1059 patients who had transurethral resections (TUR) of the prostate 8 cases (0.8%) with nonspecific granulomas were found. In another group of 280 patients treated by TUR for tumours of the urinary bladder 5 cases (1.8%) had granulomatous lesions in the resectates. The granulomas were observed...... was observed in the granulomas. The findings are compared to previously reported cases of iatrogenic granulomas in the prostate, the urinary bladder and other organs. It is concluded that the granulomas arise as a local reaction to previous surgery, maybe involving hypersensitivity to locally altered collagen....... only in patients with prior surgical trauma of the prostate and the bladder with an incidence of 14% and 6.5%, respectively. None of the patients had systemic diseases. Morphologically, two types of granulomas were observed, foreign-body-type and necrotizing. Carbonization rests were frequently noticed...

    Full Text Available Annular elastolytic giant cell granuloma is a condition characterized histologically by damaged elastic fibers associated with preponderance of giant cells along with absence of necrobiosis, lipid, mucin, and pallisading granuloma. It usually occurs on sun-damaged skin and hence the previous name actinic granuloma. A similar process occurs on the conjunctiva. Over the past three decades only four cases of conjunctival actinic granuloma have been documented. All the previous patients were females with lesions in nasal or temporal bulbar conjunctiva varying 2-3 mm in size. We report a male patient aged 70 years presenting with a 14 mm × 7 mm fleshy mass on right lower bulbar conjunctiva. Clinical differential diagnoses were lymphoma, squamous cell carcinoma in situ and amyloidosis. Surgical excision followed by histopathology confirmed it to be a case of actinic granuloma. This is the first case of isolated conjunctival actinic granuloma of such a large size reported from India.

    This study evaluates the clinical features of contact granuloma and compares the results of voice therapy in operated versus unoperated cases. Retrospective review of 123 patients with contact granuloma. Thirty-six patients had undergone one or more surgeries before phoniatric consultation. After their final operation, 33 patients had recurrence. The three patients who were cured by operation were not studied further. The course of disease in the 33 patients with recurrence was compared with that of 87 patients who did not have surgery. The hospital records were reviewed concerning age, sex, symptoms, side of granuloma, and outcome of treatment. The predominant symptoms were vocal fatigue, vocal discomfort, the need for excessive throat clearing, and hoarseness. The recurrence rate after operation was 92%. Twelve months after voice therapy, 35% of the operated group and 51% of the unoperated group were cured. The patients who had surgery had almost twice as many sessions of voice therapy as the unoperated group, and their mean recovery time was 17 months, compared with 8 months for the unoperated group. The recurrence rate after surgery was high. Surgery may prolong the recovery time. Subjective symptoms diminished during voice therapy, but we cannot confirm that it was beneficial for the healing process.

    2014-12-01

    Full Text Available Pyogenic granuloma (PG is a rare side effect of isotretinoin therapy. Oral pyogenic granuloma developing during isotretinoin treatment has not been reported so far. A 22-old-male patient, who had been given oral isotretinoin treatment for severe nodular acne, was admitted with the complaint of a painless and red nodule in his lower gum at the end of the second month of the treatment. The patient did not report any history of trauma or dental treatment. Dermatologic examination revealed a hemorrhagic nodule measuring 1.5x1 cm in size in the lower gums of the cutting and canine teeth. The lesion was excised completely. Histopathological examination disclosed acanthosis and hyperkeratosis in epidermis, subepidermal vascular proliferation, edema, and sparsely scattered inflammatory cell groups. The mechanism by which isotretinoin causes pyogenic granulomas is not exactly known. It should be considered that this rare side effect can be gingival in patients taking isotretinoin and the regular oral examination should not be neglected.

  1. Granuloma formation in leishmaniasis: A mathematical model.

    Leishmaniasis is a disease caused by the Leishmania parasites. The two common forms of leishmaniasis are cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL). VL is the more severe of the two and, if untreated, may become fatal. The hallmark of VL is the formation of granuloma in the liver or the spleen. In this paper, we develop a mathematical model of the evolution of granuloma in the liver. The model is represented by a system of partial differential equations and it includes migration of cells from the adaptive immune system into the granuloma; the rate of the influx is determined by the strength of the immune response of the infected individual. It is shown that parasite load decreases as the strength of the immune system increases. Furthermore, the efficacy of a commonly used drug, which increases T cells proliferation, increases in an individual with stronger immune response. The model also provides an explanation why, in contrast to humans, mice recover naturally from VL in the liver. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Full Text Available In dental clinic of Hospital University Science Malaysia (HUSM, there were cases with Localized Gingival Enlargement (LGE in the oral cavity with occlusal interference. In this study, three cases were observed. They were a 13 - year- old female with fibrous lge around 31 and 32 with occlusal interference in protrusive movement due to X bite, a 15 - year – old female with pyogenic granuloma near 11 & 21 with occlusal interference due to deep bite; and a 24 – year – old female who was eight months in pregnancy with pyogenic granuloma on the 34-35 and severe generalized pregnancy gingivitis with occlusal interference in centric occlusion and lateral movement. Clinical and histopathological diagnosis of the first case showed fibrous epulis, whereas the second and third cases disclosed pyogenic granuloma. Chronic trauma of the gingiva due to occlusal interference was assumed to be the cause of those LGE in case 1 and 2, while in case 3 poor oral hygiene and chronic trauma were assumed to be the etiologic factors.

Relato do Caso: Paciente de seis anos, sexo feminino com história de tumoração em conjuntiva tarsal inferior do olho direito há seis meses. Foi realizada exérese da lesão. O laudo anátomo-patológico mostrou reação inflamatória granulomatosa do tipo corpo estranho com células gigantes multinucleadas fagocitando material birrefringente, compatível com fibras sintéticas. Discussão: O granuloma de fibras sintéticas de conjuntiva é raro e descrito principalmente em crianças, com acometimento unilateral, em conjuntiva tarsal inferior ou fundo de saco inferior. O freqüente contato com material de pelúcia nesta faixa etária tem sido apontado como fator etiológico. Granuloma de fibras sintéticas de conjuntiva deve ser considerado no diagnóstico diferencial de lesões tumorais de conjuntiva em crianças.Purpose: To report a case of conjunctival synthetic fiber granuloma. Case Report: Six-year old female presented with an inferior conjunctival tumor in the right eye for six months. The lesion was excised and histopathological examination revealed granulomatous inflammation and multinucleated giant cells phagocy birefringent material, recognized as synthetic fibers. Discussion: Synthetic fiber granuloma of the conjunctiva is an uncommon lesion described mainly in children. Usually it occurs unilaterally and situated in the inferior conjunc-tival fornix. The contact of the eye with toys containing synthetic fibers in this age group could explain the origin of the lesion. Synthetic fiber conjunctival granuloma should be included in the differential diagnosis of conjunctival tumors in children.

    Full Text Available Cholesterol granulomas are rare round or ovoid cysts. They contain cholesterol crystals surrounded by foreign bodies of giant cells and are characterized by chronic inflammation. Large cholesterol granuloma can compress surrounding tissue especially cranial nerves. There are several types of surgery for the resection of cholesterol granuloma. We describe 4 cases of cholesterol granuloma operated on via transnasal endoscopic approach. In this report, we describe radiologic and pathologic features of this lesion and explain the advantages and disadvantages of transsphenoidal endoscopic approach for these rare lesions.

    For more than 25 years, Teflon was the most commonly used material for injection laryngoplasty. However, the incidence of Teflon granuloma and the consequent deterioration of glottic function ultimately led to the development of other injectable materials, and as a result, Teflon granulomas are no longer frequently encountered. We present a case of Teflon granuloma that was unusual in that (1) a long period of time had elapsed between the injection and the granuloma formation and (2) there was no change in the patient's glottic function.

    Recurrent trigeminal neuralgia after microvascular decompression (MVD) may be due to insufficient decompression, dislocation of the implant to pad the neurovascular contact, or the development of granuloma. Here, we report on our experience with Teflon granuloma including its treatment and histopathological examination. In a series of 200 patients with trigeminal neuralgia MVD was performed with Teflon felt according to Jannetta's technique. In three patients with recurrent facial pain Teflon granuloma was found to be the cause for recurrence. In each instance, the granuloma was removed for histopathological examination. Mean age at the first procedure was 62.3 years and at the second procedure 66.3 years. Recurrence of pain occurred between 1 and 8.5 years after the first procedure. MRI scans demonstrated local gadolineum enhancement in the cerebellopontine angle, and CT scans showed local calcification. Intraoperatively dense fibrous tissue was found at the site of the Teflon granuloma. Histopathological examination revealed foreign body granuloma with multinuclear giant cells, collagen-rich hyalinized scar tissue, focal hemosiderin depositions, and microcalcifications. The Teflon granuloma was completely removed, and a new Teflon felt was used for re-decompression. Patients were free of pain after the second procedure at a mean of 40.3 months of follow-up. Teflon granuloma is a rare cause for recurrent facial pain after MVD. Small bleeding into the Teflon felt at surgery might trigger its development. A feasible treatment option is surgical re-exploration, nerve preserving removal of the granuloma, and repeat MVD.

    Cholesterol granuloma of the petrous apex is a readily recognizable and treatable entity that is more common than previously realized. Cholesterol granuloma grows slowly in the petrous apex as a mass lesion until it produces hearing loss, tinnitus, vertigo, and facial twitching. Twelve cases of cholesterol granuloma of the petrous apex are illustrated; ten of these analyzed in detail, especially with respect to CT findings. A sharply and smoothly marginated expansile lesion in the petrous apex, isodense with plain and nonenhancing on CT, is in all probability a cholesterol granuloma. Preoperative recognition by CT is important for planning proper treatment.

  11. Copy number variation of FCGR genes in etiopathogenesis of sarcoidosis.

    Directory of Open Access Journals (Sweden)

    Marlena Typiak

    Full Text Available We have previously revealed that, in contrast to polymorphism of FCGR2B and FCGR3B, polymorphism of FCGR2A, FCGR2C and FCGR3A genes, encoding receptors for Fc fragment of immunoglobulin G (Fcγ receptors, play a role in increased level of circulating immune complexes with occurrence of Mycobacterium tuberculosis heat shock proteins in patients with sarcoidosis. However, this immunocomplexemia might also be caused by decreased clearance by immune cells due to a changed copy number of FCGR genes. Thus, the next step of our study was to evaluate copy number variation of FCGR2A, FCGR2B, FCGR2C, FCGR3A and FCGR3B in this disease. The analysis was carried out by real-time quantitative PCR on 104 patients and 110 healthy volunteers. Despite previously detected variation in allele/genotype frequencies of FCGR in sarcoidosis and its particular stages, there was no copy number variation of the tested genes between sarcoidosis or its stages and healthy control, as well as between stages themselves. A relevant increase in copy number of FCGR2C and FCGR3B in Stage IV of sarcoidosis vs. other stages and controls was detected, but this observation was based on a limited number of Stage IV patients. Hence, polymorphism of FCGR genes seems to be more important than their copy number variation in etiopathogenesis of sarcoidosis in patients from the Polish population.

  12. Macrophage polarization drives granuloma outcome during Mycobacterium tuberculosis infection.

    Mycobacterium tuberculosis, the causative agent of tuberculosis (TB), induces formation of granulomas, structures in which immune cells and bacteria colocalize. Macrophages are among the most abundant cell types in granulomas and have been shown to serve as both critical bactericidal cells and targets for M. tuberculosis infection and proliferation throughout the course of infection. Very little is known about how these processes are regulated, what controls macrophage microenvironment-specific polarization and plasticity, or why some granulomas control bacteria and others permit bacterial dissemination. We take a computational-biology approach to investigate mechanisms that drive macrophage polarization, function, and bacterial control in granulomas. We define a "macrophage polarization ratio" as a metric to understand how cytokine signaling translates into polarization of single macrophages in a granuloma, which in turn modulates cellular functions, including antimicrobial activity and cytokine production. Ultimately, we extend this macrophage ratio to the tissue scale and define a "granuloma polarization ratio" describing mean polarization measures for entire granulomas. Here we coupled experimental data from nonhuman primate TB granulomas to our computational model, and we predict two novel and testable hypotheses regarding macrophage profiles in TB outcomes. First, the temporal dynamics of granuloma polarization ratios are predictive of granuloma outcome. Second, stable necrotic granulomas with low CFU counts and limited inflammation are characterized by short NF-κB signal activation intervals. These results suggest that the dynamics of NF-κB signaling is a viable therapeutic target to promote M1 polarization early during infection and to improve outcome.

    Sarcoidosis and idiopathic pulmonary fibrosis (IPF) are two common forms of interstitial lung disease. Fatigue is a recognised feature of sarcoidosis but an association between IPF and fatigue has not been investigated. To investigate the frequency and severity of fatigue in these groups, and variables affecting fatigue scores. A cross-sectional questionnaire study of patients with sarcoidosis and IPF followed-up at a single hospital was undertaken. Questionnaire data included validated measures of fatigue, anxiety, depression, sleepiness and dyspnoea, plus measures of disease severity including spirometry data. Questionnaires were administered to 232 patients (82 healthy volunteers, 73 sarcoidosis patients and 77 IPF patients). Sarcoidosis patients had statistically higher sleepiness scores but no significant difference was seen between overall measures of fatigue, anxiety or depression. Stratification by severity revealed a non-statistically significant tendency towards more severe fatigue scores in sarcoidosis. Regression analysis failed to identify any significant predictor variables measured in the sarcoidosis cohort, though in the IPF group both dyspnoea and sleepiness scores were significant predictors of fatigue (R2=0.74). Both sarcoidosis and IPF patients suffer with fatigue, although sarcoidosis patients tended towards reporting more severe fatigue scores, suggesting a subgroup with severe fatigue. The fatigue experienced by the two groups appears to be different; sarcoidosis patients report greater frequency of mental fatigue whereas IPF patients appear to suffer exhaustion, potentially related to dyspnoea. Dyspnoea and sleepiness scores modeled the majority of fatigue in the IPF group, whereas no single factor was able to predict fatigue in sarcoidosis.

    Full Text Available Even tiny despicable skin signs may eventually unveil systemic illnesses enabling a prompt start of medication and better prognosis. Here, we present a case of a 28-year-old female patient who came to the office complaining of a „minor irritation” on the left eyebrow that was a discrete and asymptomatic 5mm infiltrated apple jelly coloured papule that had started 6 months earlier. Biopsy of a second similar lesion discovered on left forearm showed granulomatous features of sarcoidosis. Under subsequent systemic investigation, the presence of sarcoidosis in other organs was found to be positive as stage II pulmonary sarcoidosis, and also with reticulo-endothelial involvement manifested by enlarged mediastinal lymph nodes. This case highlights the skin as a mirror to internal multisystemic disease and also the importance of investigating even small and discrete lesions with care and in depth.

    The diagnosis of cardiac sarcoidosis, particularly when there is no overt systemic involvement, is frequently delayed because of its varied manifestations. Focal left ventricular wall motion abnormalities were recognised in five patients with sarcoidosis. Three patients showed abnormal regional wall motion in the basal portion of the ventricular septum and free wall with sparing of the apex. The angiographic appearances supported the echocardiographic findings which were atypical of ischaemic heart disease. The remaining two patients both had diffuse left ventricular hypokinesia, with a focal abnormality that was most pronounced in the anteroapical region; this pattern is often seen with coronary disease. The recognition by echocardiography or angiography of focal abnormalities of wall motion affecting the basal portion of the ventricular septum should suggest the possibility of myocardial sarcoidosis even in the absence of recognised systemic manifestations.

    Familial Blau syndrome and sporadic early-onset sarcoidosis (EOS) are both systemic granulomatous diseases evoked by the spontaneous activation of mutated NOD2. In Japan, the R334W amino acid substitution is more frequently identified, whereas the R334Q mutation is rare and, in contrast to western countries where disease causing mutations are typically hereditary, most Japanese cases derive from sporadic mutations. Recently, a case with a six-base deletion in the NOD2 gene was reported. This Blau syndrome/EOS patient presented with the unpainful soft swelling of the dorsal side of the wrist and ankles, as well as flexion contracture at the proximal interphalangeal joint that gradually appeared during their clinical course. These features are useful for the differential diagnosis of Blau syndrome/EOS from juvenile idiopathic arthritis. Owing to their characteristic clinical symptoms, Blau and EOS patients can be identified earlier if medical experts become more acquainted with these distinctions. Even though specific treatment based on pathophysiologic mechanism has not been explored yet, early diagnosis will prevent the progression to severe impairment, which can severely affect patients' lives.

    Full Text Available Injuries caused by venomous and poisonous aquatic animals may provoke important morbidity in humans. The phylum Echinoderma include more than 6000 species of starfish, sea urchins, sand dollars, and sea cucumbers some of which have been found responsible for injuries to humans. Initial injuries by sea urchins are associated with trauma and envenomation, but later effects can be observed. Sea urchin granuloma is a chronic granulomatous skin disease caused by frequent and successive penetration of sea urchin spines which have not been removed from wounds. The authors report a typical case of sea urchin granuloma in a fisherman and its therapeutic implications.Os acidentes por animais aquáticos traumatizantes e venenosos podem provocar morbidez importante em humanos.

    Full Text Available Background Sarcoidosis is a chronic inflammatory disease with a myriad of clinical manifestations. Treatment involves immunosuppression with corticosteroids or steroid-sparing agents. A proportion of patients does not respond to or are intolerant to therapy. Targeted immunotherapy with biologic agents has emerged as a novel approach with plausible mechanistic reasons to warrant study. Aims The aim of this review was to evaluate the evidence for the efficacy of biological therapy in sarcoidosis. Methods We conducted a systematic literature review and meta-analysis of all published randomised-controlled trials (RCT evaluating biological therapy in sarcoidosis, using MEDLINE and Embase databases, through to September 2017. The search terms included sarcoidosis, infliximab, adalimumab, etanercept, golimumab, certolizumab, rituximab, abatacept, tocilizumab, anakinra, ustekinumab, secukinumab. Only articles reporting RCTs were selected. Improvements in respiratory disease were assessed by changes in forced vital capacity (FVC by weighted mean difference (WMD. There were insufficient data on outcome measures in other organ systems to comparatively assess efficacy. Results The search identified 2,324 studies of which only 5 provided relevant and original data. This comprised a total of 364 patients, evaluating pulmonary, cutaneous and ocular sarcoidosis. One study in pulmonary disease and one study in cutaneous disease demonstrated improvements in the primary outcome. In pulmonary disease, meta-analysis of the treatment effect of anti-TNF therapy versus placebo on FVC revealed a WMD of 1.69 per cent (95 per cent confidence interval, 1.44–1.94. Conclusion There are insufficient data to suggest the long-term efficacy of anti-TNFα inhibitors in the treatment of sarcoidosis. This may be due to heterogeneity, small sample sizes and the lack of consistent reporting of outcome measures.

    Sarcoidosis is a granulomatous multisystemic disorder that rarely involves subcutaneous tissue. We describe the MR imaging findings of a subcutaneous sarcoidosis in a patient that presented with a nontender, palpable soft tissue mass on the left buttock, which was confirmed after surgical excision. The MR images showed the presence of a subcutaneous mass that breached the adjacent fascia with an irregular outline and homogeneous, slightly higher signal intensity than the surrounding muscle as seen on a T2-weighted image and with homogeneous enhancement after contrast injection. The lesion could not be differentiated from a sarcoma or a malignancy.

    Angiotensin-converting enzyme is used as a marker for sarcoid activity. We describe a case of remission of cutaneous and lymphatic sarcoidosis in a patient treated with an ACE inhibitor for congestive heart failure and hypertension; the remission has continued over 4 years of follow-up. Because this is a report of only one case, there is a possibility of sampling error. Whether the patient's remission in this case was a serendipitous spontaneous remission that happened to occur during ACE inhibitor therapy or whether ACE inhibitor therapy can play a role in the treatment of sarcoidosis needs to be determined in a large clinical trial.

    Granuloma faciale (GF) is a rare cutaneous disorder categorized as a localized form of small vessel vasculitis. Clinically, it manifests as single or multiple, well-demarcated, red-brown plaques, papules and nodules, nearly always confined to the face. Herein, we report a 39-year-old man with multiple red-brown, infiltrated plaques on his face and extrafacial lesions on the back, shoulders, and both arms. Skin biopsy revealed typical histopathological findings of GF. The patient failed to respond to pulsed dye laser, but intralesional triamcinolone combined with cryotherapy led to an acceptable response.

    Granuloma faciale (GF) is a rare, chronic skin disorder in which numerous treatment modalities have been used without any consistent long-term effect. We report three cases of GF, two of which were successfully treated with the Laserscope potassium-titanyl-phosphate 532-nm laser within 2 weeks and one with topical tacrolimus ointment 0.1%. Our observations suggest that these new treatment modalities for GF, which we report here for the first time, can provide effective and non-invasive treatment for this disease.

    The association between superior laryngeal nerve (SLN) paresis and laryngeal granuloma formation has not been described earlier. The aim of this study was to present a series of patients with isolated unilateral SLN paresis who developed contralateral vocal process granulomas. The study design was a retrospective chart review including all patients presenting to Indiana University from February 2006 to August 2007 with laryngeal electromyography (LEMG)-documented unilateral SLN paresis and evidence of laryngeal granuloma on videostroboscopy. Patient history, examination, LEMG findings, and response to treatment were recorded. Three cases of unilateral SLN paresis associated with contralateral vocal process granulomas were identified. In all patients, videostroboscopy examination demonstrated shortening of the ipsilateral vocal fold on adduction and asymmetric contact of the vocal processes at the site of granuloma formation. All patients failed to respond to aggressive antireflux therapy. One patient had spontaneous recovery of the SLN paresis, with subsequent resolution of the granuloma. Two patients were successfully treated with surgical laser excision of the granulomas and injection of botulinum toxin into the normal cricothyroid muscle to alter the vocal process contact points. Vocal process granulomas can be associated with unilateral SLN paresis, potentially related to altered contact points between the vocal processes of the arytenoids.

    Contact granuloma is a difficult-to-treat laryngeal disorder associated with vocal abuse, habitual throat clearing, and laryngopharyngeal reflux. It has a high propensity for persistence and recurrence despite many treatment alternatives. To present our experience with recurrent contact granuloma treated with microlaryngoscopic excision and botulinum toxin injection. Case series. The follow-up period had a mean (range) of 41 (11-88) months. Tertiary referral university clinic. Twenty patients with recurrent, grade 3 and grade 4 contact granuloma whose lesion was excised at least once after failure of conservative treatments. Microlaryngoscopic excision and botulinum toxin type A injection into the region of the bilateral thyroarytenoid and lateral cricoarytenoid muscles. Disappearance of contact granuloma. Seventeen patients were cured of their contact granuloma. Three patients experienced recurrences: 2 received botulinum toxin injection only as outpatients and recovered. The other patient required reexcision and reinjection under general anesthesia. These 3 patients were free of granuloma at their last follow-up. After failed conservative treatment, microlaryngoscopic excision and botulinum toxin type A injection is successful in the treatment of recurrent contact granuloma. Removing recurrent granulomas can result in a low recurrence rate if botulinum toxin type A is added at the time of removal.

  12. Transcriptional reprogramming in nonhuman primate (rhesus macaque tuberculosis granulomas.

    Full Text Available In response to Mtb infection, the host remodels the infection foci into a dense mass of cells known as the granuloma. The key objective of the granuloma is to contain the spread of Mtb into uninfected regions of the lung. However, it appears that Mtb has evolved mechanisms to resist killing in the granuloma. Profiling granuloma transcriptome will identify key immune signaling pathways active during TB infection. Such studies are not possible in human granulomas, due to various confounding factors. Nonhuman Primates (NHPs infected with Mtb accurately reflect human TB in clinical and pathological contexts.We studied transcriptomics of granuloma lesions in the lungs of NHPs exhibiting active TB, during early and late stages of infection. Early TB lesions were characterized by a highly pro-inflammatory environment, expressing high levels of immune signaling pathways involving IFNgamma, TNFalpha, JAK, STAT and C-C/C-X-C chemokines. Late TB lesions, while morphologically similar to the early ones, exhibited an overwhelming silencing of the inflammatory response. Reprogramming of the granuloma transcriptome was highly significant. The expression of approximately two-thirds of all genes induced in early lesions was later repressed.The transcriptional characteristics of TB granulomas undergo drastic changes during the course of infection. The overwhelming reprogramming of the initial pro-inflammatory surge in late lesions may be a host strategy to limit immunopathology. We propose that these host profiles can predict changes in bacterial replication and physiology, perhaps serving as markers for latency and reactivation.

    Summary Laryngeal granulomas present as contact and postintubation ulcers and granulomas. Essentially, a contact granuloma is a pseudotumor of the lateral wall of the posterior glottis. The most common etiological factor is voice abuse, with predisponing factors such as reflux disease. Postintubation ulcers and granulomas, although of different etiology, according to all the other traits belong to this clinical entity. The therapy of choice is conservative treatment. Surgical laser excision is indicated for resistant cases and those whose size is causing respiratory distress. Treatment of laryngeal granulomas with zinc supplementation is reported in the literature as one of the forms of conservative treatment, and we wanted to consider it in this review. Zinc is an essential mineral that plays a vital role in many biochemical reactions and is considered very important for wound healing. PMID:28356836

    2004-08-01

    Granuloma faciale is an uncommon disease of unknown etiology that is often misdiagnosed clinically and by general pathologists. To describe the clinicopathological features of a series of patients with granuloma faciale. Eleven patients diagnosed with granuloma faciale between 1990 and 2002 were included in the study. Granuloma faciale was diagnosed in 11 patients (9 male and 2 female, mean age 53.45 years). All of them presented facial cutaneous lesions and two of them also developed extrafacial lesions. Histologically, in 8 cases the infiltrate was limited to the upper half of the dermis. Two specimens showed fibrinoid necrosis. Concentric fibrosis around small blood vessels was demonstrated in 5 patients. The presence of abundant fibrosis in 5 of our patients similar to that observed in erythema elevatum diutinum suggests that granuloma faciale and erythema elevatum diutinum may be produced by similar or the same pathogenic mechanism.

    2014-01-01

    A 68-year-old woman was referred to the Oculofacial Plastic and Reconstructive Surgery service for evaluation of a left upper eyelid lesion that was worrisome for carcinoma. The mass measured 8 × 8 mm; it was well-circumscribed, pink, and firm with distortion of the eyelid margin, central ulceration, and loss of the lashes. The patient denied previous surgery or trauma in this area, but she had a history of blepharopigmentation (tattoo eyeliner) of all 4 eyelids approximately 7 years prior. Incisional biopsy revealed inflammatory changes consistent with a localized reaction to the tattoo pigment granules. Local kenalog injection was attempted with improvement of the overall appearance but with persistent deformity including irregularity of the margin and loss of lashes. The persistent abnormal appearance was worrisome for an underlying carcinoma missed on the initial incisional biopsy and prompted a full-thickness wedge resection and reconstruction of the abnormal area. The results of biopsy of the excised tissue confirmed absence of malignant neoplasm and showed changes consistent with tattoo granuloma. Tattoo granuloma of the eyelid should be considered in the differential diagnosis of eyelid lesions worrisome for carcinoma in patients with a history of blepharopigmentation.

    Full Text Available A case of a canine oral eosinophilic granuloma in a 14-year-old female crossbred is described. The dog was presented with a history of ptyalism, halitosis, local pain, decreased appetite, and blood staining noted on food and water bowls. Clinical, hematologic, and biochemical examinations, abdominal ultrasonography, and 3-view chest radiographs were performed, and no metastases were found. Histopathologic examination of two 6 mm punch biopsies from the oral lesion revealed the presence of eosinophilic granulomatous lesions in the submucosa. After treatment with corticosteroids and wide spectrum antibiotics no significant changes in clinical signs and lesion size were observed. Electrochemotherapy (ECT, a novel tumor treatment routinely used for cutaneous and subcutaneous tumors in human patients in the European Union since 2006, was used to treat the eosinophilic granuloma. The procedure was performed under general anesthesia, followed by intravenous administration of bleomycin. Six weeks after treatment a complete response with disappearance of the mass and improvement of clinical signs were observed.

    The sarcoidosis is a systemic granulomatosis affecting most frequently the lungs and the mediastinum. An acute renal failure reveals exceptionally this disease. It's a retrospective study implicating 12 cases of sarcoidosis complicated of acute renal failure. The aim of this study is to determine epidemiological, clinical, biological and histological profile in these cases and then to indicate the interest to consider the diagnosis of sarcoidosis in cases of unexplained renal failure. Extra-renal complications, therapeutic modalities and the outcome were determined in all patients. Our series involved 12 women with an average age of 40 years. Biological investigations showed an abnormal normocalcemia in 7 cases, a hypercalcemia in 5 cases, a hypercalciuria in 10 cases and polyclonal hypergammaglobulinemia in 7 cases. An acute renal failure was found in all patients with a median creatinin of 520 umol/L. For all patients, the renal echography was normaln however, the kidney biopsy showed tubulo-interstitial nephritis. The extra-renal signs highlighting pulmonary interstitial syndrome in 5 cases, a sicca syndrome in 4 cases, mediastinal lymph nodes in 2 cases, a lymphocytic alveolitis in 3 cases, an anterior granulomatous uveitis in 2 cases and a polyarthritis in 5 cases. Five patients benefited of hemodialysis. The treatment consisted of corticosteroid in all cases. The follow up was marked by complete resolution of clinical and biological signs. The diagnosis of renal sarcoidosis must be done quickly to prevent renal failure. PMID:26834928

    Full Text Available Sarcoidosis is a multisystem granulomatous disorder of unknown etiology and it may rarely be associated with a second disorder. Celiac disease is an immune-mediated enteropathy characterized with malabsorption caused by gluten intolerance, and several reports indicate an association between celiac disease and sarcoidosis. In addition, although celiac disease is associated with several extraintestinal pathologies, venous thrombosis has been rarely reported. Herein we present a rare case report of a patient with a diagnosis of sarcoidosis, celiac disease and deep venous thrombosis because of the rare association of these disorders. The patient was admitted with abdominal pain, weight loss, chronic diarrhea and a 5-day history of swelling in her right leg. A diagnosis of deep venous thrombosis was achieved by doppler ultrasonographic examination. The diagnosis of celiac disease was made by biopsy of duodenal mucosa and supported with elevated serum level of anti-gliadin IgA and IgG, and a diagnosis of sarcoidosis was achieved by transbronchial needle aspiration from the subcarinal lymph node during flexible bronchoscopy.

    Sarcoidosis is a granulomatous multisystem disorder of unclear etiology that involves any organ, most commonly the lung and the lymph nodes. It is hypothesized that the disease derives from the interaction between single or multiple environmental factors and genetically determined host factors. Multiple potential etiologic agents for sarcoidosis have been proposed without any definitive demonstration of causality.We report the case of two patients, husband (57 years old) and wife (55 years old), both suffering from sarcoidosis. They underwent a lymph node biopsy by mediastinoscopy which showed a "granulomatous epithelioid giant cell non-necrotising chronic lymphadenitis". They had lived up to 3 years ago in the country in a farm, in contact with organic dusts, animals such as dogs, chickens, rabbits, pigeons; now they have lived since about 3 years in an urban area where there are numerous chemical industries and stone quarries. The aim of this case report was to focus on environmental factors that might be related to the pathogenesis of the sarcoidosis.

    2017-02-01

    Ethnicity is strongly associated with variable clinical presentation in sarcoidosis but the association between ethnicity and clinical characteristics has not previously been described in patients of Polynesian ancestry, Maori and Pacific Islander (PI). The objective of this study was to describe the clinical characteristics of sarcoidosis in Maori and PI patients and determine if those were different to European patients. A retrospective review of the medical records of 406 patients (69 Maori/PI) attending a specialist interstitial lung disease (ILD) clinic. The population (207 females, mean age at presentation: 36) reflected the current New Zealand census data (2013) with only people of Indian ethnicity over-represented. Parenchymal lung involvement was uncommon in Maori and PI patients (21% Scadding stage 2, 2% stage 3), and no patient had extensive pulmonary fibrosis (stage 4). Computed tomography (CT) patterns of sarcoid parenchymal lung involvement were less commonly reported for Maori/PI. There were no differences in respect of baseline lung function or requirement for treatment. Ocular and skin involvement occurred more frequently in Maori and PI (P = 0.0045, P = 0.03), and erythema nodosum was more common in Caucasians (P = 0.0008). People of Polynesian ancestry appear to have less pulmonary and more extra-pulmonary manifestations of sarcoidosis. This adds to our knowledge that sarcoidosis heterogeneity is influenced by ethnicity. © 2016 Asian Pacific Society of Respirology.

  7. An epidemiological perspective of the pathology and etiology of sarcoidosis.

    Science.gov (United States)

    Sawahata, Michiru; Sugiyama, Yukihiko

    2016-08-01

    To update current knowledge on the pathology and etiology of sarcoidosis, here we review previous epidemiological research and discuss age-related differences and historical changes in the clinical characteristics of sarcoidosis we identified over the last four decades in Japan. Extrathoracic lymph node involvement was more common in young patients, while extrathoracic involvement of non-lymphatic organs and hypercalcemia were more common in older patients. Most patients in their 20s presented with bilateral hilar lymphadenopathy, but this was consistently less common among older patients. Over time, the distribution of age at diagnosis has shifted toward the older age group in the United States, Denmark, and Japan. In Japan, the incidence rate has been decreasing among young people, but there has consistently been a second peak among postmenopausal women. Age-related differences in the clinical presentation of sarcoidosis may reflect the pathways of causative antigens and the strengthening of immunoregulatory mechanisms with age. Internal and external environmental factors, such as exposure to diverse microorganisms, ovarian insufficiency, and active vitamin D deficiency, that may contribute to the onset of sarcoidosis must be identified in order to develop strategies for prevention and treatment.

    2017-01-01

    Objective For lung cancer complicated with sarcoidosis, there are no exact features that indicate whether lymphadenopathy is metastatic. This makes the validity of surgery uncertain for clinicians. The aim of this study was to clarify the clinical features of pulmonary sarcoidosis complicated by lung cancer, especially from the viewpoint of evaluating lymphadenopathy. Methods We retrospectively reviewed medical records from 2004 to 2013 at our institution, and 18 patients who were diagnosed with sarcoidosis and lung cancer were thus found to be eligible. We investigated the relationship between the clinical and pathological findings of their swollen lymph nodes. Results Of 18 patients, 11 conducted surgery, and the postoperative pathological evaluation of swollen lymph nodes was done in 8 of the patients. Postoperative N factor in all these patients was 0, even though lymphatic metastasis had been suspected preoperatively because of the unbalanced distribution of lymphadenopathy or the accumulation of fluorodeoxyglucose. Conclusion In patients with lung cancer complicated by sarcoidosis, the clinical assessment of the state of lymphadenopathy is difficult to make. However, as many of them tend to be benign, we suggest that surgical resection should be considered for a complete cure in the absence of any remote metastasis.

    The aim of this case-control study was to investigate the prevalence of exercise intolerance, muscle weakness and fatigue in sarcoidosis patients. Additionally, we evaluated whether fatigue can be explained by exercise capacity, muscle strength or other clinical characteristics (lung function tests, radiographic stages, prednisone usage and inflammatory markers). 124 sarcoidosis patients (80 males) referred to the Maastricht University Medical Centre (Maastricht, the Netherlands) were included (mean age 46.6±10.2 yrs). Patients performed a 6-min walk test (6MWT) and handgrip force (HGF), elbow flexor muscle strength (EFMS), quadriceps peak torque (QPT) and hamstring peak torque (HPT) tests. Maximal inspiratory pressure (P(I,max)) was recorded. All patients completed the Fatigue Assessment Scale (FAS) questionnaire. The 6MWT was reduced in 45% of the population, while HGF, EFMS, QPT and HPT muscle strength were reduced in 15, 12, 27 and 18%, respectively. P(I,max) was reduced in 43% of the population. The majority of the patients (81%) reported fatigue (FAS ≥22). Patients with reduced peripheral muscle strength of the upper and/or lower extremities were more fatigued and demonstrated impaired lung functions, fat-free mass, P(I,max), 6MWT and quality of life. Fatigue was neither predicted by exercise capacity, nor by muscle strength. Besides fatigue, exercise intolerance and muscle weakness are frequent problems in sarcoidosis. We therefore recommend physical tests in the multidisciplinary management of sarcoidosis patients, even in nonfatigued patients.

    The aim of the present study was to evaluate the expression and distribution of different classes of matrix metalloproteinases (MMPs) in radicular cysts and periapical granulomas. Twenty consecutive specimens of radicular cysts and 20 of periapical granulomas were selected. Expression of MMP-2, -9, -8, -13, -3 was immunohistochemically evaluated. The intensity of expression of the MMPs was evaluated using a semi-quantitative analysis: low = +; intermediate = ++; high = +++. Positive expression of MMPs was present with different distribution. MMP-9 expressed differently in the lesions. Indeed, in periapical granulomas low expression was found in endothelial cells and fibroblasts, whilst high intensities were only detected in inflammatory cells. On the contrary, in radicular cysts the high intensities were mainly present in keratinocytes and fibroblasts. MMP-8 was mainly expressed in inflammatory cells of periapical granulomas. MMP-2 and -3 presented a low intensity of expression in both groups. MMP-13 showed a variable pattern of distribution in the different cell types of the two different lesions. The present investigation supports the role of MMPs in the inflammatory process leading to the development of radicular cysts and periapical granulomas. The results of the present study suggested that the increased enlargement of radicular cysts, compared to periapical granulomas, might be related to a higher expression of MMP-9. On the other hands, the higher intensity of expression of MMP-8 in periapical granulomas could be related to an active inflammatory process. MMP-8 could play an important role in the inflammation processes during the development of periapical lesions.

    Granuloma formation around parasite eggs during schistosomal infection is considered to be controlled by Th2 cytokines. However, it is still controversial which cell populations are responsible for the host Th2 cytokine-dependent granuloma formation. Basophils have recently attracted attention because of their ability to produce large amounts of IL-4. Therefore, we investigated whether basophils play an essential role in the induction of granuloma formation induced by Schistosoma mansoni eggs. Together with our previous observation that basophil numbers increased markedly in the spleen at 7 weeks postinfection, immunohistochemical staining using anti-mMCP8 monoclonal antibody (mAb) showed basophil infiltration in the granulomatous lesions formed around parasite eggs. To examine the roles of basophils more directly, we treated mice with anti-CD200R3 mAb to deplete basophils. Depletion of basophils resulted in a reduction of basophil number with concomitant downregulation of egg granuloma formation at 7 weeks postinfection. Moreover, we observed a significant reduction in the size of egg granulomas formed in basophil-depleted mice in the pulmonary granuloma model. Taken together, these findings indicated that basophils are essential for S. mansoni egg-induced granuloma formation, and this may serve as a novel therapeutic target in ameliorating the pathology of schistosomiasis. © 2013.

    Rationale: Genetic variation plays a significant role in the etiology of sarcoidosis. However, only a small fraction of its heritability has been explained so far. Objectives: To define further genetic risk loci for sarcoidosis, we used the Immunochip for a candidate gene association study of immune-associated loci. Methods: Altogether the study population comprised over 19,000 individuals. In a two-stage design, 1,726 German sarcoidosis cases and 5,482 control subjects were genotyped for 128,705 single-nucleotide polymorphisms using the Illumina Immunochip for the screening step. The remaining 3,955 cases, 7,514 control subjects, and 684 parents of affected offspring were used for validation and replication of 44 candidate and two established risk single-nucleotide polymorphisms. Measurements and Main Results: Four novel susceptibility loci were identified with genome-wide significance in the European case-control populations, located on chromosomes 12q24.12 (rs653178; ATXN2/SH2B3), 5q33.3 (rs4921492; IL12B), 4q24 (rs223498; MANBA/NFKB1), and 2q33.2 (rs6748088; FAM117B). We further defined three independent association signals in the HLA region with genome-wide significance, peaking in the BTNL2 promoter region (rs5007259), at HLA-B (rs4143332/HLA-B*0801) and at HLA-DPB1 (rs9277542), and found another novel independent signal near IL23R (rs12069782) on chromosome 1p31.3. Conclusions: Functional predictions and protein network analyses suggest a prominent role of the drug-targetable IL23/Th17 signaling pathway in the genetic etiology of sarcoidosis. Our findings reveal a substantial genetic overlap of sarcoidosis with diverse immune-mediated inflammatory disorders, which could be of relevance for the clinical application of modern therapeutics PMID:26051272

    Full Text Available Aim: To review a general hospital′s experience with sarcoidosis and the clinical pattern of the disease among Saudis. Methods: A retrospective file review was carried out on all patients with a proven diagnosis of sarcoidosis in a general hospital in Eastern Saudi Arabia over a period of 11 years (1998-2008. Results: Sixty-nine patients, of whom 33 cases were included in the analyses, were diagnosed to have sarcoidosis during the study period. There were 18 females and 15 males. The mean age was 44.5 years (SD 17. The most common presentations were cough (48%, dyspnea (21%, joint pain (18%, splenomegaly (12%, hepatomegaly (9%, and lymphadenopathy (5%. The biochemical analysis showed elevated calcium levels in 6% and elevated angiotensin converting enzyme (ACE in 14 (46.7%. The tuberculin skin test was negative in all tested patients (n = 29 except one patient. The patients were classified using the modified Scadding classification system. None of the patients was in stage 0, 39.4% were in stage 1, 45% were in stage 2 and 15% were in stage 3.. The diagnosis in all patients was proven histologically. The outcome was favorable in most patients (85%, and in 6% of the patients, the course was chronic and progressive, although 66% received active treatment. Conclusion: Sarcoidosis does occur in native Saudis. The clinical presentation of these patients was similar to the western pattern of disease with some differences such as relative lack of cardiac, eye, parotid, and central nervous system involvement. The rarity of cardiac and central nervous system involvement was comparable with other Middle Eastern studies. Sarcoidosis, though rare in our community, should still be considered in the differential diagnosis of patients with the typical presentation after excluding tuberculosis.

    Sarcoidosis is a granulomatous disease of unknown cause, which affects all systems, especially the lungs and the lymphatic system. Genetic and environmental factors are held accountable for the etiology. Based on the general opinion, sarcoidosis develops after exposure to a specific environmental agent by genetically susceptible individuals.  The present study aimed to evaluate the disease susceptibility of the GSTT1 and GSTM1 gene polymorphisms in the patients with sarcoidosis. The present study included 78 patients; 38 patients with histopathologically verified sarcoidosis and 40 control subjects. Multiplex PCR method was used to determine the GSTT1 and GSTM1 gene polymorphisms. The genotype was determined based on the bands formed in the agarose gel electrophoresis. The statistical analysis was done using the chi-square test. The positive/negative genotype rates were 79%/21% and 53%/47%, respectively in the case group for the GSTT1 and GSTM1 gene polymorphisms, whereas the positive/negative genotype rates were 77%/23% and 55%/45% in the control group. There was no statistically significant difference in the positive and negative genotypes compared with the case group and the control group for the GSTT1 and GSTM1 gene polymorphisms (p > 0.05). The results from the present study suggest that there is not any association with the control group for the disease susceptibility of the GSTT1 and GSTM1 gene polymorphisms in patients with sarcoidosis, and this result should be supported by large-scale studies because of the limited number of cases in the present study.

    Differentiation between tuberculosis (TB) and sarcoidoisis is sometimes extremely difficult. Sequential occurrence of sarcoidosis and TB in the same patient is uncommon. We present the case of a young man, with a proven diagnosis of sarcoidosis who later developed TB after completion of treatment for sarcoidosis. A 32-year-old male patient presented with low-grade fever since two months. Physical examination revealed cervical lymphadenopathy. Initial fine needle aspiration cytology (FNAC) of the cervical lymph node was suggestive of granulomatous inflammation; the chest radiograph was normal. Repeat FNAC from the same lymph node was suggestive of reactive lymphoid hyperplasia. The patient was treated with antibiotics and followed-up. He again presented with persistence of fever and lymphadenopathy and blurring of vision. Ophthalmological examination revealed uveitis, possibly due to a granulomatous cause. His repeat Mantoux test again was non-reactive; serum angiotensin converting enzyme (ACE) levels were raised. This time an excision biopsy of the lymph node was done which revealed discrete, non-caseating, reticulin rich granulomatous inflammation suggestive of sarcoidosis. The patient was treated with oral prednisolone and imporved symptomatically. Subsequently, nearly nine months after completion of corticosteroid treatment, he presented with low-grade, intermittent fever and a lymph node enlargement in the right parotid region. FNAC from this lymph node showed caseating granulomatous inflammation and the stain for acid-fast bacilli was positive. He was treated with Category I DOTS under the Revised National Tuberculosis Control Programme and improved significantly. The present case highlights the need for further research into the aetiology of TB and sarcoidosis.

    Granuloma inguinale, or Donovanosis, is a rare, sexually transmitted ulcerative disease primarily affecting the genital area. In this report, we present a case of a 50-year-old man that was diagnosed with granuloma inguinale after a 2-month history of a penile ulcer. Histological analysis demonstrated the presence of Donovan bodies within macrophages, confirming the diagnosis. He was subsequently treated with trimethoprim/sulfamethoxazole with improvement in the ulcer. This case serves as a reminder to clinicians that although granuloma inguinale is rarely encountered in the US, it should still be suspected in patients with non-healing penile ulcers.

Hepatic granulomas are a very rare finding, so far reported in very few cases. We report a 64-year-old patient with Salmonella enteritis who was found to have multiple 1.4 to 1.6 cm hypoechoic liver masses on ultrasound of the abdomen which on biopsy revealed hepatic granulomas. This case highlights the importance of keeping the differential diagnosis of Salmonella typhi (S. typhi in mind in a patient with hepatic granulomas.

    Full Text Available Cholesterol granuloma is a well-characterized entity comprised of a foreign-body giant cell-reaction that forms in response to the presence of cholesterol crystals. It is usually found in the middle-ear or mastoid process in patients with diseases associated with chronic inflammation such as cholesteatoma and otitis media. They are rarely seen in the mediastinum. Osseous metaplasia is an exceedingly rare feature of cholesterol granulomas only reported twice in the literature. We report a case of a cholesterol granuloma of the anterior mediastinum with osseous metaplasia in a 75 year-old man that was found incidentally during urgent coronary artery bypass graft surgery.

    Lobular capillary hemangioma is a vascular neoplasm that commonly occurs as a cutaneous tumor. When it involves the skin and mucosal surfaces, ulceration and suppuration may occur, hence the classic term of pyogenic granuloma. Intravenous pyogenic granuloma is a rare solitary form of lobular capillary hemangioma that usually occurs in the veins of the neck and upper extremities. We report the ultrasonographic and magnetic resonance imaging findings of a pyogenic intravenous granuloma localized in the right cephalic vein. The imaging and pathological findings and the differential diagnoses are discussed. (orig.)

    Granuloma faciale (GF) is a rare cutaneous disorder characterized by one to several soft, erythematous to livid papules, plaques or nodules, usually occurring on the face. Extrafacial lesions are uncommon. A 52-year-old lady with multiple asymptomatic, variously sized brownish-black colored, firm, sharply circumscribed plaques resembling keloids on both cheeks and extrafacial lesions on the right arm and the right breast is presented for its unusual keloidal appearance and typical histopathological findings. She failed to respond to oral dapsone 100 mg daily administered for 3 months. Local infiltration of triamcinolone combined with cryotherapy led to only partial flattening of the lesions. All the skin lesions were excised surgically followed by flap transfer grafting on both cheeks. The cosmetic outcome was highly satisfactory.

    Full Text Available Introduction: Pyogenic granuloma (PG or granuloma pyogenicum is essentially a capillary hemangioma on the skin or a mucosal surface which shows an exophytic growth pattern and has a lobulated appearance. The most common sites are skin (40% and mucosal surfaces (predominantly oral cavity, 60%. We intend to report all available cases of PG of gastrointestinal (GI tract, diagnosed at the Henry Ford hospital, a tertiary referral center. Patients and Methods: A retrospective review of pathological database was performed on all GI biopsies in the last 10 years using diagnostic codes and pathology codes searching for PG of the GI tract. Results: A total of 23 cases of pathologically diagnosed PG was diagnosed over a 10 year period. The median age of patients was 64 with almost equal gender distribution (47.8% were males, and 52.2% were females. The most common location of PG was sigmoid colon (65.2%, esophagus (17.4% and transverse colon (13%. PG presented as a polyp in 16 patients (69.6%. The most common indication for endoscopy in these cases was screening colonoscopy (30.4% cases. Discussion: PG of GI tract is rare. To date, only about 15-20 cases have been reported in the literature and most cases have been reported from Japan and Korea. This is the largest case series of this rare pathological lesion of the GI tract. Most cases of PG were diagnosed on an endoscopy done for an unrelated reason in our series. Hence, most cases were asymptomatic, unlike previously reported cases which were mostly associated with GI bleeding.

  13. A mycosis-like granuloma of fish

    1955-01-01

    Mycoses of systemic distribution are rarely observed in fresh-water fish in this country. In a recent review of atypical cell growths in fishes, Nigrelli cited the only known instance of a mycetoma in a North American fresh-water fish which occurred in the head of fingerling landlocked salmon from an Idaho hatchery. The fungus associated with this granuloma was characterized by a branching septate mycelium. Rucker reported a streptomycete which was pathogenic to blueblack salmon. This organism produced internal nodules containing masses of hyphae but no inflammatory response. A pathogenic fungus has been observed frequently in marine fish, however, and in both marine and fresh-water fish in Europe. This organism was tentatively classified as a Phycomycete in or near the order Chytridiales and was assigned to the genus and species Ichthyophonus hoferi, later reclassified as Ichthyosporidium hoferi. The graduloma described in this report occurs in fresh-water trout and is apparently caused by a budding, yeast-like form with no hyphae which evokes a tremendous inflammatory reaction. Morphologically, the organism does not resemble the previously described Ichthyosporidium. The lesions were first seen accidentally in sections prepared from a diplobacillus infection of brook trout termed “kidney disease.” Subsequently, the granuloma was observed in three widely separated infections involving the diplobacillus in each instance.The histological material was received in a fixed condition; thus, no cultural data was available and the nomenclature and classification of the mycotic organism were not attempted. The present distribution of the disease, however, with its potential threat to domestic fish populations, seemed to warrant a description and discussion of the disease. Efforts are in progress to culture the organism.

    Full Text Available Sarcoidosis, a systemic granulomatous syndrome invariably affecting the lung, typically spontaneously remits but in ~20% of cases progresses with severe lung dysfunction or cardiac and neurologic involvement (complicated sarcoidosis. Unfortunately, current biomarkers fail to distinguish patients with remitting (uncomplicated sarcoidosis from other fibrotic lung disorders, and fail to identify individuals at risk for complicated sarcoidosis. We utilized genome-wide peripheral blood gene expression analysis to identify a 20-gene sarcoidosis biomarker signature distinguishing sarcoidosis (n = 39 from healthy controls (n = 35, 86% classification accuracy and which served as a molecular signature for complicated sarcoidosis (n = 17. As aberrancies in T cell receptor (TCR signaling, JAK-STAT (JS signaling, and cytokine-cytokine receptor (CCR signaling are implicated in sarcoidosis pathogenesis, a 31-gene signature comprised of T cell signaling pathway genes associated with sarcoidosis (TCR/JS/CCR was compared to the unbiased 20-gene biomarker signature but proved inferior in prediction accuracy in distinguishing complicated from uncomplicated sarcoidosis. Additional validation strategies included significant association of single nucleotide polymorphisms (SNPs in signature genes with sarcoidosis susceptibility and severity (unbiased signature genes - CX3CR1, FKBP1A, NOG, RBM12B, SENS3, TSHZ2; T cell/JAK-STAT pathway genes such as AKT3, CBLB, DLG1, IFNG, IL2RA, IL7R, ITK, JUN, MALT1, NFATC2, PLCG1, SPRED1. In summary, this validated peripheral blood molecular gene signature appears to be a valuable biomarker in identifying cases with sarcoidoisis and predicting risk for complicated sarcoidosis.

    Cysticercosis is an infection caused by the metacestode larval stage of Taenia parasites in tissues and elicits a host-parasite reaction in which the immune response may be decisive in the disease development. The aim of this study was to evaluate the role of IFNγ (IFN-gamma) in the experimental model of subcutaneous infection with Taenia crassiceps (T. crassiceps) cysticerci using IFNγ knockout mice. Male C57BL/6 and C57BL/6 KO IFNγ mice 8-12 weeks of age were inoculated with T. crassiceps cysticerci into the subcutaneous tissue of the dorsum. At 7 and 30 (acute phase), 60 and 90 (chronic phase) days post infection, animals from each group had their blood and the subcutaneous tissues collected for serologic and pathological studies. IFNγ and IL-4 were dosed and the histopathological analysis was performed. In the presence of IFNγ there was the establishment of a mixed Th1/Th2 systemic immune profile. This profile also locally induced the granuloma formation which was constituted by cells that played important roles in the parasitary destruction and that were likely associated to the Th1 axis of mixed immune response. On the other hand, the absence of IFNγ appears to favor the parasitary growth which may be related to the development of a systemic Th2 immune response. This profile influenced the granuloma formation with immunoregulatory properties and appears to be important in the collagen synthesis. Copyright © 2016 Elsevier Inc. All rights reserved.

    Background Extrapulmonary involvement by sarcoidosis is observed in about 30–40% of patients with sarcoidosis. Little is known about the frequency and clinical characteristics of sinonasal sarcoidosis. Methods We retrospectively analyzed 12 cases of biopsy-proven sinonasal sarcoidosis. Patients were identified from a patient population of 1360 patients with sarcoidosis at the Outpatient Clinic for Sarcoidosis and Rare Lung Diseases at LungClinic Grosshansdorf, a tertiary care hospital for respiratory medicine. Results The most frequent signs and symptoms were nasal polyps (4 cases), epistaxis (3 cases), nasal crusts (8 cases) and anosmia (5 cases). Pulmonary sarcoidosis of the patients was staged as stage I (n = 1) and stage II (n = 11) on chest radiographs. Spirometry was normal in 11 patients. 7 patients had a diffusion capacity of the lung for carbon monoxide of less than 90% of predicted. Other organs were affected in 8 patients. All patients received systemic corticosteroid treatment and most patients received topical steroids. 5 patients received steroid sparing agents. Repeated sinus surgery had to be performed in 4 patients. Conclusions Sinonasal involvement is a rare disease manifestation of sarcoidosis with a frequency slightly lower than 1% in our patient population. The clinical course of sinonasal sarcoidosis can be complicated by relapse despite systemic immunosuppressive treatment and repeated sinus surgery. PMID:24070015

    Full Text Available The aim of this case report is to present the laryngeal granuloma in 23 year old female patient. Case outline: The 23 year old female was admitted for examination, because of long lasting, progressive hoarseness. In anamnesis, we found that she has undergone general anesthesia for 8 times, in the early childhood. We performing direct laryngoscopy with complete otorhinolaryngologic examination, rigid endovideostroboscopy and the large granuloma of the larynx was found. Conclusions: Laryngeal granuloma of vocal cords affected mainly men, except for cases associated with laryngeal intubation. We should keep in mind that postintubation laryngeal granuloma might develop after tracheal intubation, so care must be taken to avoid the potential complication.

    For the purpose of improving the surgical effect of contact granuloma of larynx, a new surgical method was used and its effect observed. Under suspension laryngoscope, a part of cartilage of vocal process of arytenoid cartilage was removed until the cartilage was covered by local soft tissue after the granuloma was excised. Among 8 patients in this group, 7 were male, 1 female. Their ages ranged from 29 to 51(median 45 years old). The courses were 1 to 9 months (median 7 months). All patients experienced 1 to 5 times operations (median 2 times). Using the new operative method, all 8 patients were cured for only 1 time, without recurrence followed- up for 1.5 years. The granuloma were very easily recurred after the operation. The reason might be related to the exposure and inflammation of the local vocal process cartilage. The difficult key of the operation is exposure of granuloma and cartilage of vocal process because of intratracheal anesthetic tube.

    Eosinophilic granuloma is a common expression of Langerhans cell histiocytosis and corresponds with typical bone lesions. The radiographic appearance of eosinophilic granuloma in the jaw is variable and not specific. It may resemble periodontitis, radicular cyst, or malignancies. The purpose of this report is to describe the characteristic radiographic features of eosinophilic granuloma of a 39-year-old male. The lesion in the anterior mandible was first diagnosed as radicular cyst because the radiographic findings were ovoid radiolucent lesion with well-defined border. However, careful interpretation revealed a non-corticated border and floating tooth appearance that were the characteristic radiographic features for the differential diagnosis. Early clinical signs of eosinophilic granuloma can occur in the jaw and a bony destructive lesion might be mistaken for periodontitis or an odontogenic cystic lesion; therefore, careful interpretation of radiographs should be emphasized.

    In 1059 patients who had transurethral resections (TUR) of the prostate 8 cases (0.8%) with nonspecific granulomas were found. In another group of 280 patients treated by TUR for tumours of the urinary bladder 5 cases (1.8%) had granulomatous lesions in the resectates. The granulomas were observed...... only in patients with prior surgical trauma of the prostate and the bladder with an incidence of 14% and 6.5%, respectively. None of the patients had systemic diseases. Morphologically, two types of granulomas were observed, foreign-body-type and necrotizing. Carbonization rests were frequently noticed...... in the granulomatous lesions and the configurations and anatomical distribution of the granulomas suggest a common pathogenesis by electrocauterization. Immunohistochemically, histiocytic cells were stained by antibodies against lysozyme. In the prostate, no reaction by antibodies against prostate specific antigen...

    A 42-year-old female acquired an acute respiratory infection one week after working in a sphagnum moss packing plant. Three and one half months later direct laryngoscopic examination, done because of persistent hoarseness, revealed granulomas of the left true cord. Initial biopsy showed noncaseating granulomas, and a repeat biopsy with fungal cultures grew Sporothrix schenckii. The patient was treated with an oral solution of saturated potassium iodide and gradually improved although mild hoarseness has persisted.

    Hyalinizing granulomas are benign fibrotic lesions that generally present multiple nodules seen on radiological examinations, which are frequently cavitary and/or calcified lesions. We report a case of a 28 year-old-woman with hyalinizing granulomas probably secondary to a previous tuberculosis infection. Hyalinizing granulomas should be included in the differential diagnosis of patients with multiple pulmonary nodules. (author)

  10. Granuloma Transplantation: An Approach to Study Mycobacterium-Host Interactions

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available The host-pathogen biology during infection with Mycobacterium tuberculosis is incredibly complex and despite accelerating progress in research, remains poorly understood. Our limited understanding hinders the development of new drugs, next generation vaccines, and novel therapies. The granuloma is the site where mycobacteria are both controlled and allowed to persist, but it remains one of the least studied aspects of the host-pathogen relationship. Here, we review the development, application, potential uses, and limitations of a novel model of granuloma transplantation as a tool to study specific host-pathogen interactions that have been difficult to probe. Application of this new model has already contributed to our understanding of granuloma cell traffic, repopulation, and the relationship between systemic immunity and mycobacteria-containing granulomas. The data collected highlight the dynamic interaction between systemic and local immune processes and support a paradigm that defines the granuloma as a highly dynamic structure. Granuloma transplantation also has special potential as a novel latency model that can contribute to our understanding of host protection factors and bacterial mutants, and serve as a platform for drug testing.

    Mycobacterium tuberculosis infection in humans triggers formation of granulomas, which are tightly organized immune cell aggregates that are the central structure of tuberculosis. Infected and uninfected macrophages interdigitate, assuming an altered, flattened appearance. Although pathologists have described these changes for over a century, the molecular and cellular programs underlying this transition are unclear. Here, using the zebrafish-Mycobacterium marinum model, we found that mycobacterial granuloma formation is accompanied by macrophage induction of canonical epithelial molecules and structures. We identified fundamental macrophage reprogramming events that parallel E-cadherin-dependent mesenchymal-epithelial transitions. Macrophage-specific disruption of E-cadherin function resulted in disordered granuloma formation, enhanced immune cell access, decreased bacterial burden, and increased host survival, suggesting that the granuloma can also serve a bacteria-protective role. Granuloma macrophages in humans with tuberculosis were similarly transformed. Thus, during mycobacterial infection, granuloma macrophages are broadly reprogrammed by epithelial modules, and this reprogramming alters the trajectory of infection and the associated immune response.

    The granuloma is the defining feature of the host response to infection with Mycobacterium tuberculosis (Mtb). Despite knowing of its existence for centuries, much remains unclear regarding the host and bacterial factors that contribute to granuloma formation, heterogeneity of presentation, and the forces at play within. Mtb is highly adapted to life within the granuloma and employs many unique strategies to both create a niche within the host as well as survive the stresses imposed upon it. Adding to the complexity of the granuloma is the vast range of pathology observed, often within the same individual. Here, we explore some of the many ways in which Mtb crafts the immune response to its liking and builds a variety of granuloma features that contribute to its survival. We also consider the multitude of ways that Mtb is adapted to life in the granuloma and how variability in the deployment of these strategies may result in different fates for both the bacterium and the host. It is through better understanding of these complex interactions that we may begin to strategize novel approaches for tuberculosis treatments. PMID:26577238

    We report a case of fulminant sarcoidosis in a 28-year-old man presenting with skin nodules, multifocal small and large joint arthralgias, and blurred vision. Characteristic bone, soft tissue, articular, and CNS findings were evident on multimodality imaging. Bony abnormalities included near-complete destruction of a distal phalanx, ''lace-like'' lucent lesions, erosive arthritis, lytic lesions with and without sclerotic margins, and bone marrow replacement visible only on MRI. The extent of bony disease at time of presentation was unusual. We review the widely varying reported prevalence of imaging findings of bony sarcoidosis in the literature, and discuss reasons for this variability. We found that musculoskeletal findings at US and MRI were less specific than radiographic and CT findings, but were useful in quantifying extent of disease. (orig.)

    Early onset sarcoidosis is a granulomatous disease which is characterized by synovitis, polyarthritis, skin and eye involvement. We report the skeletal features of one patient with a family history and clinical symptoms suggestive of early onset sarcoidosis (EOS) which was confirmed by skin biopsy. Radiographs reveal postarthritic deformities of the MCP joints, contractures, a coarsened trabecular pattern at the PIP joints and small bone cysts resembling osteitis cystoides multiplex. Similar lesions were described in radiographs of the older sister and an uncle of our patient. This is the first report demonstrating bone cysts and erosions which could be a diagnostic feature in this rare disease and may help to differentiate other rheumatoid disorders. (orig.)

    Sarcoidosis is a systemic granulomatous disease of unknown aetiology, which is characterized by bilateral hilar lymphadenopathy and pulmonary disease. Clinically detected cardiac involvement occurs in 5% of sarcoid patients, although cardiac manifestations are discovered in 25% of the cases at autopsy. Sarcoid heart disease frequently causes atrioventricular block. The authors present the case of a 44-year-old man with bradycardia. On admission, second degree Mobitz II, then third degree atrioventricular block was diagnosed. Coronarography showed normal coronary arteries. 2.5 years following artificial Biotronik Entovis DR type pacemaker implantation, sudden cardiac death occurred. Autopsy revealed sarcoidosis with cardiac, pulmonary, splenic, renal and lymph node involvement. In case of young or middle-aged patients with atrioventricular block, it is best to search for other causes if the most common coronary origin can be excluded. Orv Hetil. 2017; 158(27): 1067-1070.

    We evaluated the magnetic resonance imaging (MRI) of the lacrimal gland in 18 patients with sarcoidosis. All the cases were imaged by conventional spin-echo technique using a 1.5 T super-conductive MR system by General Electric. We identified enlargement of the lacrimal gland in 7 patients. The signal intensity of lacrimal glands in these cases were characterized by isointensity on T1-weighted and proton density image and by high intensity on T2-weighted images. Hilar lymphadenopathy was present in 5 of them. Other ocular disorders related to sarcoidosis were present in 15 patients. Enlargement of the lacrimal gland was correlated with retinal vasculitis and not with hilar lymphadenopathy. (author).

    The first manifestation of sarcoidosis is usually at the pulmonary level. The case is described of a 40-year-old female patient, who presented with an increased volume of the lacrimal gland and mechanical ptosis of upper left eyelid as the first expression of this disease. The diagnosis of systemic sarcoidosis with primary presentation of the lacrimal gland was made after performing several immunological studies with negative results, imaging studies, and taking of glandular and lymph node biopsies. A favourable response was achieved with oral methotrexate treatment. Copyright © 2017 Sociedad Española de Oftalmología. Publicado por Elsevier España, S.L.U. All rights reserved.

    Vertebral involvement in sarcoidosis is rare and its clinical and imaging features are non-specific. Indeed, because the lesions are hard to differentiate from metastatic disease based on imaging alone, a histological confirmation is advised. Fatty replacement is a well-known finding indicating stabilization and healing in both benign and malignant conditions. It can be used as an indicator of a favorable disease course and response to treatment. We report the case of a 43-year-old woman with multifocal vertebral sarcoidosis lesions and long-term follow-up showing progressive and gradual fatty involution on magnetic resonance imaging (MRI) during 4 years of steroid treatment with a final favorable outcome.

    Full Text Available Cranial palsies are a very rare feature of SLE. Similarly, peripheral sensory-motor axonal neuropathy is very uncommon in SLE. The combination of the two as the presenting symptoms of SLE is a diagnostic challenge particularly in an elderly male patient with a known diagnosis of sarcoidosis. This case serves to highlight the diagnostic considerations in such a patient. The lack of response to standard therapy and the presence of subtle clues like anemia, proteinuria, and mild serositis should prompt the physician to look for alternate diagnoses. The potential association of SLE and sarcoidosis is also discussed. SLE can be present in elderly male patients with cranial and peripheral neuropathy.

    Full Text Available The present report describes a 60-year-old Caucasian woman who presented with progressive dyspnea, cough and wheeze. A computed tomography scan of the chest showed innumerable bilateral inflammatory pulmonary nodules with bronchovascular distribution and a mediastinal and hilar infiltrative process with calcified lymphadenopathy leading to narrowing of lobar bronchi and pulmonary arteries. An echocardiogram revealed pulmonary hypertension. Bronchoscopy showed left vocal cord paralysis and significant narrowing of the bilateral bronchi with mucosal thickening and multiple nodules. Transbronchial biopsy was compatible with sarcoidosis. Despite balloon angioplasty of the left lower lobe and pulmonary artery, and medical therapy with oral corticosteroids, her symptoms did not significantly improve. To the authors’ knowledge, the present report describes the first case of pulmonary sarcoidosis resulting in major airway, vascular and nerve compromise due to compressive lymphadenopathy and suspected concurrent granulomatous infiltration. Its presentation mimicked idiopathic mediastinal fibrosis.
