    Full Text Available Histoplasmosis is a systemic mycotic infection caused by the dimorphic fungus, Histoplasma capsulatum. Systemic histoplasmosis has emerged as an important opportunistic infection in human immunodeficiency virus (HIV patients and those in endemic areas. Reported cases of histoplasmosis have been low in India with less than 50 cases being reported. We are reporting a case of disseminated histoplasmosis with oral and cutaneous involvement in an HIV seronegative patient.

    Full Text Available Histoplasmosis, a systemic mycosis caused by the dimorphic fungus Histoplasma capsulatum var capsulatum and Histoplasma capsulatum var duboisii is endemic to many parts of the world. The clinical manifestations range from acute or chronic pulmonary infection to a progressive disseminated disease. After initial exposure to the fungus, the infection is self-limited and restricted to the lungs in 99% of healthy individuals. The remaining 1%, however, progress to either disseminated or chronic disease involving the lungs, liver, spleen, lymph nodes, bone marrow or rarely, the skin and mucous membranes. Mucocutaneous histoplasmosis is frequently reported in patients with acquired immune deficiency syndrome (AIDS, but it is rare in immunocompetent hosts. A 60-year-old male presented with asymptomatic swelling of the hard palate and crusted papules and nodules over the extremities, face and trunk. Clinically, the diagnoses of cutaneous cryptococcosis versus histoplasmosis was considered in this patient. A chest X-ray revealed hilar lymphadenopathy. Enzyme-linked immunosorbent assay (ELISA for human immunodeficiency virus (HIV was nonreactive. Skin biopsy revealed multiple tiny intracellular round yeast forms with a halo in the mid-dermis. Culture of the skin biopsy in Sabouraud′s dextrose agar showed colonies of Histoplasma capsulatum. Despite an investigation including no evidence of underlying immunosuppression was found, he was started on IV amphotericin-B (0.5 mg/kg/day. However, the patient succumbed to his disease 2 days after presentation. We report a rare case of disseminated cutaneous histoplasmosis in an immunocompetent individual.

    Disseminated cutaneous histoplasmosis is an opportunistic infection in patients with acquired immunodeficiency syndrome. We report a series of 23 cases (21 men, two women; median age 29 years) with disseminated cutaneous histoplasmosis seen at two hospital centres. Most of the patients (21/23) were classified as stage C3. The most common dermatological findings were papules, crusting plaques, nodules and ulcers, mainly located on the face and chest. Of the 23 cases, 15 (65%) had pulmonary involvement. Amphotericin B and itraconazole were the main drugs used for treatment. Treatment response was variable: four of the patients were cured, six improved and remain stable, nine patients died, and four patients were lost to follow-up.

    Full Text Available Introduction: Histoplasmosis is a systemic mycosis caused by the dimorphic fungus Histoplasma capsulatum. We report a case of disseminated cutaneous histoplasmosis with mucocutaneous involvement in an AIDS patient paradigmatic of the multifaceted nature of the disease, which is an expression of the immune reconstitution inflammatory syndrome (IRIS.Patient presentation: A 39-year-old man presented with a three month history of asymptomatic papules and nodules with necrotic centres involving the centrofacial region. The patient was diagnosed as being HIV-positive a month earlier and was commenced on antiretroviral treatment. Two weeks after the development of skin lesions, the patient complained of a sore throat and hoarseness of his voice. A fibre-optic laryngoscopy and biopsies of the skin, larynx and liver were performed.Management and outcome: The CD4 counts increased from 2 cells/µL to 124 cells/µL, whereas the viral load decreased from one million to less than 20 copies/mL. A fibre-optic laryngoscopy revealed a supraglottitis with ulceration on the epiglottis. Histology of the liver, larynx and sections of the skin demonstrated pandermal necrotising granulomatous inflammation. Grocott-Gomori methenamine silver and Periodic acid–Schiff (PAS stains revealed a relative paucity of intracellular, narrow-neck budding fungal organisms. Culture findings confirmed the diagnosis of histoplasmosis. The patient was treated with intravenous amphotericin B for two weeks followed by oral itraconazole 100 mg twice a day, with an excellent response to treatment.Conclusion: We present this case to remind clinicians that disseminated histoplasmosis in AIDS patients may occur as an expression of IRIS. A sudden onset of hoarseness with cutaneous lesions in a patient with disseminated disease should alert one to possible laryngeal histoplasmosis. Prompt recognition and treatment will avert the potential fatal complications of this disease.

    2016-05-01

    Disseminated histoplasmosis has a diverse and non-specific range of clinical signs and symptoms. In a significant minority of patients, cutaneous lesions are apparent at the time of initial presentation, affording an opportunity to establish the diagnosis from a skin biopsy. The most frequently reported clinical scenario in immunocompromised patients with cutaneous involvement is that of multiple papulo-nodular lesions on the face, trunk or extremities. The following report features an immunocompetent patient who presented with a solitary ulcerated plaque on the buttocks close to the anal verge. This case presentation underscores the broad spectrum of clinical presentations as well as the potential for diagnostic confusion with protozoa such as Leishmania or Trypanosoma species during histopathologic examination if special stains for fungal organisms are not performed.

    1998-01-01

    Full Text Available Acute disseminated histoplasmosis is a frequent condition in HIV carriers. Thirty-five cases of endocarditis caused by Histoplasma capsulatum have been reported in international literature, and all these descriptions correspond to a context of subacute disseminated histoplasmosis. This paper presents the case of a HIV-positive patient with fever, dyspnea, weight loss, vomiting and polyadenopathies to whom histoplasmosis was diagnosed following blood-cultures and isolation of the agent responsible for cutaneous lesions, and in whom aortic-valve vegetations were found during an echocardiogram. The patient was treated with amphotericin B and had a good outcome; subsequent echocardiograms showed no vegetations. Literature on the subject is reviewed, with special emphasis on diagnosis and treatment of previously described cases.

    Cutaneous histoplasmosis is a rare entity, although it can be seen in a substantial portion of renal transplant recipients with disseminated disease. The prognosis of disseminated disease is worse than isolated cutaneous involvement, and significant delays in diagnosis are reported. We reviewed reports of cutaneous histoplasmosis with and without dissemination in the setting of renal transplantation to examine incidence, timing of diagnosis, clinical features, and prognosis. Remarkable morphologic variability and the non-specific appearance of skin findings suggest that tissue culture is required for definitive diagnosis. Cutaneous lesions represent an easily accessible source for early diagnosis.

    Histoplasmosis is a genus of dimorphic fungi having various varieties of which the commonest one causing infection is Histoplasma capsulatum known to cause histoplasmosis. It has a varied disease spectrum ranging from an acute infection to chronic disease especially in lungs, disseminated disease and cutaneous disorder. Histoplasma capsulatum usually causes subclinical infection and serious infections only manifest in immunocompromised patients. Frank cases of infection are seen in pulmonary histoplasmosis. The spores of these organisms are seen to be strongly associated with droppings of birds and bats. A combination of these droppings and some soil types provide for an excellent environment for the proliferation of spores. Pulmonary histoplasmosis and disseminated disease are very common in AIDS patients and are a great cause of morbidity and mortality in these patients. Primary cutaneous histoplasmosis is very rare and occurs due to penetrating injuries. Once diagnosis is made, the lesions respond very well to oral itraconazole, fluconazole or amphotericicn B. We report a rare case of Cutaneous Histoplasmosis (CHP) in a 70-year-old male with complaints of multiple nodules all over his body in a HIV seronegative and otherwise immunocompetent patient.

    LACAZ Carlos da Silva

    1999-01-01

    Full Text Available A case of atypical disseminated cutaneous histoplasmosis in a five-year old, otherwise healthy child, native and resident in São Paulo metropolitan area is reported. Cutaneous lesions were clinically atypical. Histologic examination disclosed a granulomatous reaction but no fungal structures could be demonstrated by specific staining nor by immunohistochemical reaction. The fungus was isolated from biopsy material on two different occasions, confirming diagnosis of an unusual fungal infection. The fungus, originally thought to be a Sepedonium sp. due to the large sized, hyaline or brownish colored tuberculated macroconidia and to lack of dimorphism (yeast form at 37 °C produce H and M antigens, visualized by the immunodiffusion with rabbit anti-Histoplasma capsulatum hyperimmune serum. Patient?s serum sample was non reactive with H. capsulatum antigen by immunodiffusion, counterimmunoelectrophoresis and complement fixation tests, and immunoenzymatic assay failed to detect the specific circulating antigen. This serum was tested negative by double immunodiffusion when antigen obtained from one of the isolated samples was used. Both cultures were sent to Dr. Leo Kaufman, Ph.D. (Mycoses Immunodiagnostic Laboratory, CDC-Atlanta/USA, who identified them as H. capsulatum by the exoantigen and gen-probe tests. Both clinic and mycologic characteristics of the present case were atypical, suggesting the fungus isolated is an ?aberrant variant? of H. capsulatum var. capsulatum, as described by SUTTON et al. in 199719. Treatment with itraconazole 100 mg/day led to cure within 90 days

    We present the case of an 18-year-old male patient admitted with complaints of fever and rapid weight loss since 3 months. Patient had multiple umbilicated papular to nodular lesions over chin and forehead region. Complete blood count revealed bicytopenia. An excisional biopsy of the skin lesions had revealed cutaneous histoplasmosis. On further investigations for bicytopenia, histoplasmosis had been diagnosed on bone marrow trephine biopsy. For the immune status, patient's serology against HIV was negative and his CD4 lymphocyte counts were low at 161. Patient received antifungal therapy including amphotericin B and itraconazole. He showed remarkable improvement in his general condition and blood counts. A repeat CD4 count showed normal counts, and idiopathic CD4 lymphocytopenia was excluded. Disseminated histoplasmosis presenting as cutaneous lesions in an immunocompetent host is very rare, and we are not aware of any case report in the literature where there is reversible depletion of CD4 counts following antifungal treatment in an immunocompetent host of nonendemic area.

    Full Text Available Progressive disseminated histoplasmosis (PDH caused by Histoplasma capsulatum generally develops in immunocompromised patients or those on long-term systemic corticosteroid therapy. Here, we report a case of PDH in an immunocompetent patient, which is a rare occurrence. A 56- year-old male patient, whose work often led him to caves, now reported with a low-grade fever and altered sensorium. Investigations revealed hyponatremia, bilateral adrenal enlargement, and mediastinal lymphadenopathy. A rare complication of the manifestations of histoplasmosis in an immunocompetent patient, in the form of ring lesions in the brain, came to light during the clinical investigations. The patient developed generalized tonic–clonic convulsions and needed care for the critical condition 2 weeks into treatment. This case report traces the clinical course, histological and serological findings, and response to amphotericin B therapy in the patient.

    2015-01-01

    We report a case in which an HIV-infected man was cured of disseminated histoplasmosis (Histoplasma capsulatum var duboisii) after treatment by high-dose fluconazole (1,600 mg taken four times daily) for 2 months, combined with active antiretroviral therapy. The choice of fluconazole at this dosage was motivated by its availability as a generic and thus inexpensive medication, the patient's precarious status, and his critical clinical condition. At the end of the second month of treatment, the patient chose to stop the fluconazole, which he could no longer afford, while continuing the antiretroviral treatment, which was free. The clinical and laboratory improvement observed from the first week has continued to progress for more than 8 months after fluconazole treatment stopped. This single case needs - and deserves - to be confirmed in a series of patients. Nonetheless it makes it possible to envision fluconazole as a low-cost and efficacious antifungal agent for the treatment of disseminated histoplasmosis in AIDS patients in sub-Saharan Africa.

    Full Text Available Histoplasmosis is a fungal disease caused by Histoplasma capsulatum. Most infections are asymptomatic or self-limiting but some may develop acute pulmonary infections or severe and progressive disseminated infection. Disseminated histoplasmosis frequently affects the adrenal gland; however, unilateral involvement in immunosuppressed patients is the usual presentation. We report a case of a middle aged immunocompetent male with history of weight loss, fever, hepatomegaly and bilateral adrenal mass who was diagnosed to be suffering from disseminated histoplasmosis and successfully treated with Itraconazole

The majority of infections involving this dimorphic fungus are asymptomatic. Manifestations in symptomatic patients are diverse, ranging from flu-like illness to a more serious disseminated disease. We present here a case of chronic disseminated histoplasmosis mimicking a metastatic cancer. We reviewed the literature for cases of disseminated histoplasmosis presenting with hypercalcemia, focusing particularly on clinical presentation, risk factors predisposing for fungal infection, and outcome. We report a case of a 65-year-old diabetic male who presented with unexplained weight loss and hypercalcemia. Multiple brain space-occupying lesions and bilateral adrenal enlargement were evident on imaging studies. Biopsies showed caseating granulomas with budding yeast, consistent with histoplasmosis. The patient's symptoms resolved after liposomal amphotericin B and itraconazole therapy. Granulomatous diseases, including fungal infections, should be considered alongside malignancies, in patients with similar presentation.Keywords: disseminated histoplasmosis, hypercalcemia

    Full Text Available A retrospective study was carried out on 171 cases of disseminated histoplasmosis diagnosed in HIV/AIDS patients during the period 2009-2014. Although HIV diagnosis rates remained stable over the study period, a sensible increase in the number of histoplasmosis cases was observed in the last three years. Disseminated histoplasmosis was prevalent in males with an average age of 37.8 years. At diagnosis, only 54/171 (31.6% were receiving HAART, and CD4+ T-lymphocyte counts ranged from 4 to 264 cells/upsilon. Cutaneous lesions, including ulcerated papules or molluscoid plaques, were present in 110/171 (64.3%, with Histoplasma capsulatum being observed in all skin scraping specimens upon Giemsa staining. Respiratory manifestations were second in frequency with bronchoalveolar lavage showing a high diagnostic performance. Radiological findings included milliary patterns, interstitial infiltrates, and focalized condensations. Out of 141 blood cultures performed, H. capsulatum was isolated in 82 (58.2%. No significant difference in diagnostic performance was found between blood cultures and skin scraping (p = 0.6164. Other opportunistic infections were observed in 70/171 (40.9% prior to or concomitantly with histoplasmosis. Association with Mycobacterium tuberculosis was recorded in 16/171 (9.4% and one had a multi-drug resistant isolate. The severity of histoplasmosis determined the monotherapy with amphotericin B deoxycholate in 115 (67.3%, itraconazole in 42 (24.5%, and combined therapies in 14 (8.2%. Mortality was 19.9% (34/171. Finally, we emphasize that the higher prevalence in the last three years of the study should prompt the medical community to consider the diagnosis of histoplasmosis to reduce mortality of AIDS patients.

    2015-04-01

    Full Text Available Introduction: Histoplasmosis is a rare fungal disease caused by dimorphic fungi Histoplasma capsulatum. The causative fungus is present in soil, infects through inhalation and manifests in three main types-acute primary, chronic cavitary and progressive disseminated Histoplasmosis. Disseminated Histoplasmosis (DH is defined as a clinical condition where fungus is present in more than one location. Among the forms of histoplasmosis, DH is the rarest and generally found in immune-compromised individual. Here we are presenting our experiences of the series of cases of Disseminated Histoplasmosis in immune-competent individuals who have been diagnosed in our institute in last 5 years. Materials and methods: This is a single centre retrospective observational study, from May 2009 to April 2014. Only cases with Disseminated Histoplasmosis in otherwise healthy immune-competent individuals were included in the study. The Histoplasmosis is confirmed by either presence of Histoplasma in biopsy specimen from extra-pulmonary organ or by positive growth in fungal culture Result: Total seven patients met the inclusion criteria. Five out of 7 patients were male. The mean age was 35 years. Five of the 7 patients presented with fever for long duration. Six patients complained of significant weight loss before diagnosis. On examination, one patient had skin nodules, five patients had hepato-splenomegaly, and two patients had lymphadenopathy. The laboratory investigation revealed anaemia in six out of 7 patients, and pancytopenia in 3 patients. Two patients had features of hemophagocytic syndrome in the bone marrow. All of the patient had undergone treatment with conventional amphotericine B  deoxy-cholate and azole antifungal. One patient with adrenal involvement died in hospital. The patient with skin nodule had recurrent relapses. The other patients had resolution of symptoms and clinically cured. Conclusion: Disseminated Histoplasmosis is not an uncommon

    2012-01-01

    Full Text Available Histoplasmosis refers to an infection caused by histoplasma capsulatum, a dimorphic fungus. We report a rare case of cutaneous histoplasmosis in an immunocompromised patient. The diagnosis was made by the cytopathologic examination of skin scraping smear, which showed numerous intracellular and extracellular periodic acid-schiff positive rounded yeast cells. The patient showed dramatic response with itraconazole and amphotericin B. We opine that skin scrape cytology can be useful in establishing the diagnosis of the disease, specially when the other facilities are not readily available.

    Subacute disseminated histoplasmosis is an uncommon entity. Typical neuro-ophthalmologic manifestations are usually secondary to histoplasmomas or encephalitis. A 45-year-old man noted blurred vision while receiving empiric antituberculosis therapy for fever and diffuse granulomatous disease of unknown origin. Vertical-gaze palsy, right horizontal-gaze paresis, and mild right optic neuropathy were found on neuro-ophthalmologic examination. Further questioning revealed a history of frequent contact with fighting cocks from South America. Magnetic resonance images were consistent with multiple hemorrhagic infarcts, areas of inflammation, or both, and cerebral angiography showed changes consistent with vasculitis. A previously obtained biopsy specimen from the duodenum was restained and found to be positive for fungal elements. Serum antigen titers for Histoplasma capsulatum demonstrated evidence of active infection. This case is a rare example of a supranuclear ocular motility disturbance and optic neuropathy secondary to an occlusive vascular process in a patient with subacute disseminated histoplasmosis.

    Severe infections with Histoplasma capsulatum are commonly observed in patient with secondary immunodeficiency disorders. We report a two and a half years old boy previously healthy with disseminated cutaneous histoplasmosis. Using whole exome sequencing, we found an indel mutation at the CD40LG gene, suggesting a diagnosis of hyper-IgM (HIGM) syndrome, even in the absence of the usual features for the disease. Interestingly, the patient lives in a region endemic for histoplasmosis. The unusual infections in our case suggest that in children with severe histoplasmosis and resident in endemic areas, HIGM syndrome should be considered as a diagnosis. PMID:28239602

    Histoplasmosis is a progressive disease caused by dimorphic intracellular fungi and can prove fatal. Usually, it is present in immunocompromised individuals and immunocompetent individuals in the endemic zones. We report an unusual presentation of progressive disseminated histoplasmosis. The patient in the present case report was immunocompetent child and had fever, bone pains, gradual weight loss, lymphadenopathy and hepatosplenomegaly. Disseminated histoplasmosis (DH) was diagnosed on microscopic examination and fungal culture of bone marrow, blood, skin biopsy and lymph node aspirate. The patient died on seventh day of amphotericin B. In the absence of predisposing factors and classical clinical presentation of febrile neutropenia, lung, adrenal and oropharyngeal lesions, the disease posed a diagnostic challenge. Progressive disseminated histoplasmosis in children can be fatal despite timely diagnosis and therapy. In India, disseminated histoplasmosis is seen in immunocompetent hosts. All the pediatrics immunocompetent cases from India are also reviewed.

    Histoplasma capsulatum causes a spectrum of manifestations from asymptomatic to fatal disseminated disease. Disseminated histoplasmosis is mostly seen in endemic areas among immunocompromised patients such as those with AIDS. Here, we present a patient living in a non-endemic area with previously undiagnosed diabetes mellitus, who presented with septic shock and diabetic ketoacidosis (DKA), and was ultimately diagnosed with disseminated histoplasmosis. The patient rapidly recovered on administration of intravenous liposomal amphotericin followed by oral itraconazole. Uncontrolled diabetes may be a risk factor for disseminated or severe histoplasmosis in otherwise immunocompetent patients.

    The visibility of Histoplasma within histiocytes on hematoxylin and eosin is a well-known feature of disseminated histoplasmosis. However, it is unclear whether this finding can be used to differentiate disseminated histoplasmosis involving the lung from other forms of pulmonary histoplasmosis. The aim of this study was to determine whether the visibility of Histoplasma within histiocytes on hematoxylin and eosin in lung biopsies suggests disseminated disease. Lung biopsies in which Histoplasma was identified were re-examined to determine whether organisms were visible within histiocytes on hematoxylin and eosin. Clinical findings were reviewed retrospectively to determine the type of histoplasmosis. Histoplasma was visible within histiocytes on hematoxylin and eosin in lung biopsies from 4 patients (2 men, 2 women, 50-74 years) who presented with pulmonary manifestations without definite evidence of disseminated disease at the time of biopsy. Subsequently, all 4 manifested clinical and/or microbiologic features of disseminated disease (positive extrapulmonary cultures and fatal outcome in 2, positive extrapulmonary cultures in 1, and multiorgan failure and fatal outcome in 1). In contrast, organisms were identified on silver stains but could not be visualized on hematoxylin and eosin in 42 patients, none of whom showed clinical or microbiologic evidence of disseminated disease (pulmonary histoplasmoma, 38; acute pulmonary histoplasmosis, 4). In lung biopsies, the visibility of Histoplasma within histiocytes on hematoxylin and eosin suggests disseminated disease. Recognition of the significance of this finding is helpful in diagnosing disseminated disease in patients who present primarily with pulmonary manifestations without definite clinical evidence of dissemination at the time of biopsy.

    Full Text Available Histoplasmosis, a fungal disease caused by Histoplasma capsulatum, is endemic in North and South America. Except few scattered cases, the disease is considered to be a non-entity in India. Furthermore, disseminated histoplasmosis is rare in the immunocompetent individuals. We report an adolescent boy presenting as middle lobe consolidation which did not respond to antibiotics. His condition deteriorated with the development of mediastinal lymphadenopathy, pleural effusion and hepatosplenomegaly. A diagnosis of progressive disseminated histoplasmosis was established by his clinical findings as well as bronchoscopic biopsy, transbronchial needle aspiration cytology and bronchoalveolar lavage culture demonstrating Histoplasma capsulatum. The case represents a unique example of progressive disseminated histoplasmosis in an immunocompetent individual in India.

    Progressive disseminated histoplasmosis is a disease where Histoplasma capsulatum affects multiple organs due to the inability of host cellular immunity to control the infection. Progressive disseminated histoplasmosis mainly involves the bone marrow, liver, and lungs. We report an unusual initial presentation of progressive disseminated histoplasmosis presenting as acute tenosynovitis in a systemic lupus erythematosus (SLE) patient. This report highlights the point that H. capsulatum may present as focal lesions and a high level of suspicion is needed to make the diagnosis, especially in SLE patients. We specifically reviewed reported cases of progressive disseminated histoplasmosis in SLE patients, and a review of the literature is presented.

    Full Text Available Disseminated histoplasmosis is the first AIDS-defining infection in French Guiana. A retrospective cohort study studied predictive factors of disseminated histoplasmosis in HIV-infected patients between 1996 and 2008. Cox proportional hazards models were used. The variables studied were age, sex, last CD4/CD8 count, CD4 nadir, herpes or pneumocystosis, cotrimoxazole and fluconazole use, antiretroviral treatment and the notion of recent initiation of HAART. A total of 1404 patients were followed for 6833 person-years. The variables independently associated with increased incidence of disseminated histoplasmosis were CD4 count<50 per mm3, CD4 count between 50 and 200 per mm3, a CD4 nadir <50 per mm3, CD8 count in the lowest quartile, herpes infection, and recent antiretroviral treatment initiation (less than 6 months. The variables associated with decreased incidence of histoplasmosis were antiretroviral treatment for more than 6 months, fluconazole treatment, and pneumocystosis. There were 13.5% of deaths at 1 month, 17.5% at 3 months, and 22.5% at 6 months after the date of diagnosis of histoplasmosis. The most important predictive factors for death within 6 months of diagnosis were CD4 counts and antiretroviral treatment. The present study did not study environmental/occupational factors but provides predictive factors for disseminated histoplasmosis and its outcome in HIV patients in an Amazonian environment during the HAART era.

    Infections with Histoplasma capsulatum are rare in Germany, and mostly imported from endemic areas. Infections can present as localized or disseminated diseases in immunocompromised as well as immunocompetent hosts. A travel history may be a major clue for diagnosing histoplasmosis. Diagnostic tools include histology, cultural and molecular detection as well as serology. Here we present four cases of patients diagnosed and treated in Freiburg between 2004 and 2013 that demonstrate the broad range of clinical manifestations of histoplasmosis: an immunocompetent patient with chronic basal meningitis; a patient with HIV infection and fatal disseminated disease; a patient with pulmonary and cutaneous disease and mediastinal and cervical lymphadenopathy; and an immunosuppressed patient with disseminated involvement of lung, bone marrow and adrenal glands.

    Histoplasmosis is a disease caused by inhalation of the fungus Histoplasma capsulatum. In rare cases the disease affects immunocompetent individuals. Disseminated and severe disease is seen in immunocompromised patients. We report a case of a 45 year old immunocompromised patient presenting with weight loss and abdominal pain. Chest x-ray and computerized tomography examinations showed interstitial infiltrate and diffuse micro nodules. The initial diagnosis was miliary tuberculosis. However, the definitive diagnosis of miliary histoplasmosis was made later on. (author)

    Histoplasmosis is a systemic fungal infection caused by dimorphic fungus, Histoplasma capsulatum. Immunocompetent individuals usually have self-limiting or localized disease whereas immunocompromised individuals develop disseminated disease. The occurrence of progressive disseminated histoplasmosis in juvenile systemic lupus erythematosus is extremely rare with only one reported case in literature showing such association. Therefore, we report a case of severe opportunistic fungal infection caused by Histoplasma in a 13-year-old girl who was diagnosed with juvenile lupus erythematosus, subsequently developed septic shock and died of the disease despite of aggressive antifungal therapy.

    A 2.5-year-old intact male miniature lop rabbit (Oryctolagus cuniculus) was presented with multiple nodules surrounding the eyes, nose, mouth, and prepuce. Cytological evaluation of the periocular nodules revealed the presence of intracellular (within macrophages) and extracellular yeast organisms. The yeast organisms were approximately 3-5 µm in diameter, round to oval, with a thin clear capsule, and contained an eccentrically placed basophilic crescent-shaped nucleus. The clinical pathological interpretation was granulomatous inflammation with intralesional yeast of a morphology consistent with Histoplasma spp. The rabbit was treated with microsized griseofulvin (25 mg/kg, orally, once a day) for 12 days pending final cytological diagnosis of histoplasmosis. No significant improvement was noted during the treatment period, and humane euthanasia was performed. Postmortem examination revealed the presence of intracellular and extracellular yeast organisms in the small intestine, skin (antebrachium, perioral, palpebral, perianal, and pinnal), penis, penile urethra, rectum, axillary lymph node, and conjunctiva. Postmortem fungal culture yielded Histoplasma capsulatum. Based on clinical and postmortem findings, a definitive diagnosis of disseminated histoplasmosis was made. Disseminated histoplasmosis appears to be unreported in rabbits. Although the treatment used did not provide noticeable improvement, available information on histoplasmosis treatment in other species has been reviewed to provide useful information for future management of this condition in rabbits.

    Histoplasmosis is a fungal infection due to Histoplasma capsulatum. The African form of this mycosis, caused by Histoplasma capsulatum var. duboisii, remains rare. We report a case of disseminated African histoplasmosis with skin, lymph nodes, bones and viscera localizations. The 22-year-old patient was HIV-seronegative and was considered immunocompetent. The presence of Histoplasma capsulatum var duboisii in ulcerations and a nodule pus aspiration was confirmed by direct microscopic examination and by culture. The medical treatment was based on fluconazole. Even though a regression of the symptoms was observed, the patient died. In disseminated African histoplasmosis, an early laboratory diagnosis must be carried out for accurate treatment.

    Refractory hypoxemia secondary to acute respiratory distress syndrome (ARDS) is associated with high mortality. Extracorporeal membraneoxygenation (ECMO) is an accepted strategy for treating refractory hypoxemia in patients with ARDS but is relatively contraindicated in the setting of systemic infections. We present a case of successful ECMO use in a host with refractory hypoxemia secondary to disseminated histoplasmosis with fungemia and discuss our management approach to this difficult patient.

    A 44-year-old female presented to her general dentist with the chief complaint of a painful mouth sore of 2 weeks duration. Clinical examination revealed an irregularly shaped ulcer of the buccal and lingual attached gingiva of the anterior mandible. A biopsy was performed and microscopic evaluation revealed histoplasmosis. Histoplasmosis, caused by Histoplasma capsulate, is the most common fungal infection in the United States. Oral lesions of histoplasmosis are generally associated with the disseminated form of histoplasmosis and may present as a fungating or ulcerative lesion of the oral mucosa. The histologic findings and differential diagnosis for oral histoplasmosis are discussed.

    The frequency of histoplasmosis among solid organ transplant (SOT) recipients appears to be low where there are only a few case series, mostly among renal and liver transplant recipients. Herein we report a case of a 44-year-old woman who underwent a living-related renal transplant 18 years prior to evaluation, developed a nodule after followed by ulceration upon her posterior right leg and a second one upon her left leg 3 months and 2 months before her hospitalisation, respectively. The biopsy of lesion revealed the presence of Histoplasma spp. Bone marrow aspiration was performed and also revealed the same organism. She had initially received itraconazole without improvement of lesions, while a new lesion appeared on her left arm. Healing of all lesions could be observed after 40 days of liposomal amphotericin B when she was submitted to skin grafts on the legs and a surgical treatment on the arms, and the myelosuppression improved simultaneously. Histoplasmosis seems to be very uncommon among patients who underwent to organ solid transplantation. Most cases occur within 12-18 months after transplantation, although unusual cases have been presented many years post-transplant. There are cases reported in the literature, occurring from 84 days to 18 years after organ transplantation, but without cutaneous involvement. Our patient developed lesions on limbs and myelosuppression after 18 years of chronic immunosuppression medication. This case suggests that besides cutaneous histoplasmosis is an uncommon infection following iatrogenic immunosuppression and even rarer over a long period after the transplantation. Clinicians who care SOT recipient patients must bear in mind histoplasmosis infection as differential diagnosis in any case of cutaneous injury with prolonged fever and try to use as many tools as possible to make the diagnosis, once this disease presents a good prognosis if it is diagnosed and treated promptly.

  12. Co-infection of disseminated histoplasmosis and tuberculosis in an AIDS patient

    Directory of Open Access Journals (Sweden)

    Bruno Tomazini

    2013-10-01

    Full Text Available Histoplasmosis is a fungal disease caused by the dimorphic fungus Histoplasma capsulatum, recognized as an AIDS-defining illness since the Center for Disease Control’s revision criteria in 1985. This infection is reported to be present in 5-20% of AIDS patients, and in 95% of the cases it is manifested in its disseminated form. Serum antibodies and/or antigen research can make diagnosis, but the demonstration of the agent by culture or histopathological examination remains the gold standard methods. Co-infections in patients with AIDS are well known; however, reports on disseminated tuberculosis and histoplasmosis are scarce. The authors report the case of a female patient who presented a short-course history of weight loss, fever, and mild respiratory symptoms, with hepatosplenomegaly and lymphadenopathy. Laboratory workup called attention to anemia, altered liver, canalicular enzymes, liver function tests, high titer of lactate dehydrogenase (LDH, and pulmonary nodules on thoracic computed tomography. Incidental finding of yeast forms within the leukocytes during a routine blood cell count highlighted the diagnosis of histoplasmosis. The patient started receiving amphotericin B but succumbed soon after. The authors emphasize the possibility of this co-infection, the diagnosis of severe infection through the finding of yeast forms within peripheral leukocytes, and for the high titer of LDH in aiding the differential diagnosis.

    Disseminated histoplasmosis is caused by the dimorphic fungus Histoplasma capsulatum (H. capsulatum). The early clinical manifestations are nonspecific, often lead to diagnostic difficulty, and is misdiagnosed as tuberculosis and seen usually in immunosuppressed states. Fine needle aspiration cytology (FNAC) is a simple, safe, and quick technique to establish the initial diagnosis of H. capsulatum, thereby prompting early treatment. The skin involvement is rare in disseminated disease and we describe a case of disseminated histoplasmosis in an immunocompetent patient with unusual molluscum contagiosum like umbilicated skin lesions and FNAC of the cervical lymph node was the only tool for rapid and early confirmatory diagnosis.

He had a history of weight loss, loss of appetite, intermittent low-grade fever of 6 months duration. He had been administered empirical antituberculous therapy some months ago with no alleviation of symptoms. On examination, he was asthenic, normotensive, and anemic with hepatosplenomegaly. Ultra-sonography abdomen revealed bilateral enlarged adrenals with hepatosplenomegaly. Clinically impression was of tuberculosis disseminated malignancy. He expired within 2 days of admission. At autopsy, both the adrenals were markedly enlarged showing extensive areas of necrosis on the cut surface. Histology showed them to be brimming with colonies of yeast-forms of Histoplasma capsulatum. These organisms were also seen in the spleen, lungs and kidneys. The patient had died of septicemia following disseminated histoplasmosis that was, unfortunately, not diagnosed during his life. Histoplasmosis is amenable to treatment with Amphotericin B. Prompt diagnosis and treatment could have helped in salvaging this patient.

    Disseminated histoplasmosis (DH) is the most current revelation mode of AIDS in French Guiana. We describe the clinical and paraclinical presentation of DH, diagnostic tools, evolution and factors associated with 1-year mortality in HIV-infected patients from western French Guiana. Microbiologically proven AIDS-related DH in Saint Laurent du Maroni's hospital between May 2002 and May 2012 were retrospectively included. Among the 82 patients included, 58 (71%) were male, 44 (53%) presented concurrent histoplasmosis and HIV diagnosis and 63 (80%) had a CD4 cell count under 50 cells μL(-1). Almost all patients had weight loss (97%) and fever (95%), while 84% had digestive symptoms (63% diarrhoea), 55% lymphadenopathy, and 49% respiratory symptoms. Documented and presumed locations of H. capsulatum var capsulatum (Hcc) concerned almost all organs, with a particular affinity for the bone marrow and the digestive system. Co-infections were associated in 65%. Following treatment initiation, 10 patients (13%) died within 1 month and 17 patients (25%) died within a year. DH is a polymorphous systemic mycosis with haematological and digestive tropism. Co-infections are frequent and mortality rate is high.

    2015-01-01

    Hemophagocytic lymphohistiocytosis (HLH) is traditionally regarded as a rapidly progressive and often fatal illness. In patients with AIDS, HLH usually occurs secondary to opportunistic infections. Although popular guidelines exist for the diagnosis and management of HLH in general, no formal study has evaluated their applicability among adult patients who develop HLH in the setting of AIDS and opportunistic infections. The study reports on a case of HLH in a patient with AIDS and disseminated histoplasmosis. Eighteen other previously reported cases of HLH in the setting of AIDS and histoplasmosis were reviewed. Majority of the cases occurred in patients with a CD4 count of less than 70 cells/mm(3). Overall mortality was 44%. Not getting antifungal treatment and having Histoplasma in blood were the 2 main risk factors for death. Among the patients who had a timely diagnosis of histoplasmosis and were initiated on antifungal therapy, the survival rates were significantly better, especially in the post-2000 ad period.

    Acquired perforating dermatosis (APD) is a rare disorder characterized by transepidermal elimination of contents from dermis with minimal disruption of surrounding structures, believed to be due to altered expression of dermal proteins. Its occurrence in patients with systemic mycosis has never been reported. We report a 60-y gentleman who presented with features of adrenal insufficiency (nausea vomiting, hypotension and increased pigmentation) for 4 mo, multiple hyperpigmented pruritic nodules with central keratinous plug over extensor surface of both lower limbs along with hepatosplenomegaly of one month duration. Investigations revealed low cortisol (2.3 μg/dl; normal: 5-34 μg/dl), elevated ACTH (68 pg/ml; normal: 5-15 pg/ml), enlarged bilateral adrenals with hepatosplenomegaly on CT. Methanamine silver staining of fine needle aspiration from the adrenals and bone marrow aspiration showed numerous oval yeast cells suggestive of histoplasma. Histopathology of biopsy of one of the skin nodules revealed transepidermal elimination process characterized by invagination of epidermis with extrusion of collagen bundles suggestive of APD. Patient improved with hydrocortisone replacement and there was clinical improvement with resolution of skin lesions following amphotericin-B and itraconazole therapy. This is probably the first reported case of APD in a patient with disseminated histoplasmosis who had presented with Addison's disease.

    Histoplasmosis is well characterized as an endemic fungal disease restricted to certain areas of the USA. In Middle Europe, most patients present with acute pulmonary symptoms after travelling to endemic areas. Here, we want to illustrate the case of a 67-year-old man who presented with persistent oral ulcers, hoarseness, dysphagia, diarrhea, and weight loss to our Department of Otorhinolaryngology in December 2014. He was a retired construction worker and had a history of soil-disruptive activities in Africa and Middle and South America during employment. A positron emission tomography-computed tomography scan revealed prominent hypermetabolic lesions in the cecum and the lung, pointing towards a malignant disease. Surprisingly, histological examination of colonic and oral biopsies revealed abundant intracellular fungal elements, highly suspicious of Histoplasma capsulatum. Diagnosis was finally confirmed by panfungal polymerase chain reaction. Upon treatment with liposomal amphotericin followed by itraconazole, the severely ill patient showed an impressive clinical response. This case describes a disseminated manifestation of H. capsulatum years after the first exposure in an otherwise immunocompetent patient descending from a nonendemic area. PMID:27920657

    Full Text Available A histoplasmose é uma doença fúngica causada pela inalação de esporos de Histoplasma capsulatum. A maioria dos indivíduos normais não apresenta doença após pequena inalação, porém exposições mais prolongadas podem levar ao desenvolvimento de infecção pulmonar aguda, crônica ou disseminada. Nos pacientes imunocomprometidos a infecção é disseminada e grave. Relatamos o caso de um paciente de treze anos, imunocompetente, com febre, tosse seca e dispnéia progressiva havia dois meses. O radiograma e a tomografia computadorizada de tórax evidenciavam infiltrado intersticial com micronódulos difusos. O paciente relatava contato intenso com pássaros em sua residência. Foi submetido a biópsia pulmonar a céu aberto, que evidenciou Histoplasma capsulatum em tecido pulmonar. A cultura do fragmento da biópsia confirmou a presença de Histoplasma capsulatum sp. O paciente foi tratado com anfotericina-B por 28 dias, seguida de itraconazol por seis meses, com resolução do quadro.Histoplasmosis is a fungal disease caused by inhalation of Histoplasma capsulatum fungus. The disease does not normally affect immunocompetent individuals after a single, transient inhalation exposure. However, longer exposure may cause chronic or disseminated acute pulmonary infection. In immunocompromised patients, the infection is disseminated and severe. We report the case of a 13-year-old immunocompetent patient, presenting with fever, cough and dyspnea for one month. The chest X-ray and computed tomography scan revealed interstitial infiltrate and diffuse micronodules. The patient reported having had close and prolonged contact with birds. He was submitted to an open lung biopsy and the tissue culture was positive for Histoplasma capsulatum sp. He was treated with amphotericin B for 28 days, followed by treatment with itraconazole for 6 months, and there was complete resolution of the disease.

    Histoplasmosis is a fungal infection, having interesting synonyms such as Cave disease, Darling's disease, Ohio Valley disease, reticuloendotheliosis, Spelunker's lung and Caver's disease. The aetiological agent is a dimorphic fungus, Histoplasma capsulatum, causing chronic granulomatous disease. The route of transmission is by inhalation of dust particles from soil contaminated by excrement of birds or bats, harbouring the small spores or microconidia, which is considered the infectious form of fungus. The spectrum of illness ranges from subclinical infection of the lung to progressive disseminated disease. The major bulk of histoplasmosis infections are asymptomatic or present with mild influenza like illness and involve immunocompetent individuals. However, the immunocompromised or immunodeficient cases have disseminated/haematogenous infections with multiple organs involved and are usually fatal unless treated immediately. Laryngeal involvement is associated with the disseminated form of the disease. Histoplasmosis of larynx is a rare entity and poses diagnostic difficulty to otolaryngologists because clinically it may be mistaken for malignancy. We report an unusual case of laryngeal histoplasmosis in a man aged 60 years who presented with provisional diagnosis of tuberculosis/malignancy.

    Cryptococcosis is a fungal infection of opportunistic behavior that is unusual in immunocompetent patients. We report a rare case of disseminated cryptococcosis with cutaneous involvement in an immunocompetent individual. During hospitalization, Cryptococcus gattii was isolated from skin lesions, lung and spinal fluid. The diagnosis of disseminated cryptococcosis was confirmed and treatment was established. The patient showed improvement. Due to the probable clinical severity of the disease and the possibility that skin lesions may be the first manifestation of this illness, prompt diagnosis must be established and treatment provided.

Presentaba lesiones en piel de tronco y cara; no tenía rigidez de nuca. Se demostró infección por Histoplasma capsulatum var. capsulatum en piel y líquido cefalorraquídeo, linfopenia, anticuerpos anti Ro-SSA positivos, baja concentración del trazador en centellograma de glándulas salivales e infiltración linfocitaria en glándulas salivales, lo que permitió confirmar al diagnóstico de síndrome de Sjögren.

Comunicamos este caso para referir que una infección oportunista, como la histoplasmosis diseminada, puede ser una forma poco común de presentación del síndrome de Sjögren.Sjögren's syndrome is an autoimmune disease characterized by decreased exocrine gland secretions; patients may also present several hematological abnormalities, like lymphopenia. We describe the case of a 28 year old man who complained of headache a month of duration, with fever and vomiting in the last 48 hours. He also presented skin lesions on trunk and face, without neck stiffness. The diagnosis of duration infection was confirmed by culture from the skin biopsy and spinal fluid specimens; in addition, the presence of lymphopenia, positive anti Ro-SSA antibodies, poor concentration of the tracer in scintigraphy and lymphocytic infiltration in salivary glands confirmed the diagnosis of Sjögren's syndrome. The patient was successfully treated with liposomal amphotericin and itraconazole. We report this case to emphasize that opportunistic infections, such as disseminated histoplasmosis, may be an

    Many relapses and deaths resulting from disseminated histoplasmosis (DH) in acquired immunodeficiency syndrome (AIDS) patients have been observed in an endemic area in north-eastern Brazil. The objective of this study was to evaluate the risk factors associated with the clinical outcomes of DH/AIDS coinfection in patients from the state of Ceará, Brazil. A retrospective cohort of AIDS patients, after their hospital discharge due to first DH episode in the period 2002-2008, was followed until December 31, 2010, to investigate the factors associated with relapse and mortality. A total of 145 patients were evaluated in the study. Thirty patients (23.3%) relapsed and the overall mortality was 30.2%. The following variables were significantly (P histoplasmosis relapse was also significantly associated with mortality. In the multivariate analysis, non-adherence to HAART was the independent risk factor that was associated with both relapse (Adj OR = 6.28) and overall mortality (Adj OR = 8.03); efavirenz usage was discovered to be significant only for the overall mortality rate (Adj OR = 4.50). Adherence to HAART was the most important variable that influenced the outcomes in this specific population.

    Histoplasmosis is the first cause of acquired immunodeficiency syndrome (AIDS) and AIDS-related deaths in French Guiana. Cohort data were used to determine whether primary prophylaxis with 100 mg itraconazole for patients with CD4 counts histoplasmosis for a cost of 36,792 Euros per averted death, 1,533 per life-year saved, 4,415 Euros per averted case, when only counting the costs of itraconazole prophylaxis. Taking into account the total costs of hospitalization showed that primary prophylaxis would allow a savings of 185,178 Euros per year. Even in a scenario of low adherence, primary prophylaxis would be cost-effective in French Guiana, and presumably in the rest of the Guianas and the Amazon.

Methods To make a literature review about the clinical manifestations, pathological features, diagnosis, treatment of chronic histoplasmosis, according to 2 cases of clinical and follow-up data in our hospital from 1980 to 2012. Results Both two cases of patients have a long course, lack of early and specific symptom, multi-system involvement and no exposure history. One case has gastrointestinal, lung and adrenal gland involvement, and the other one has lung and peritoneal involvement. Both of them are misdiagnosed early, with diagnosis by pathology and good effect by the anti-fungal therapy, neither relapsed. Conclusions Chronic histoplasmosis is a rare disease and the clinical manifestations are not specific. Diagnosis depends on the typical pathological morphology and special stains, prognosis is good with active treatment.

    Histoplasmosis is the most common endemic mycoses among HIV-infected people. Patients with suppressed cell immunity mainly due to HIV are at increased risk of disseminated disease. Dermatological manifestations of immune reconstitution inflammatory syndrome (IRIS) and cutaneous manifestations of histoplasmosis similar to an IRIS event have been previously described. We report the case of a 43-year-old male who presented with cutaneous disseminated histoplasmosis due to Histoplasma capsulatum var. capsulatum 4 months after the onset of the antiretroviral therapy and some improvement in the immune reconstitution. After 2 weeks of amphotericin B and itraconazole therapy, the scheduled treatment involved fluconazole maintenance therapy, which resulted in an improvement of his skin lesions. PMID:28210571

    Mucormycosis is an uncommon opportunistic fungal infection caused by Zygomycetes. It usually affects immunocompromised, diabetic and trauma patients with infected wounds. We report a case of disseminated infection secondary to facial cutaneous mucormycosis caused by Saksenaea vasiformis in a diabetic patient who had a farming accident causing him severe head injury. The patient was treated with a combination of surgical debridement and antifungal therapy with liposomal amphotericin B, but he had a slow and fatal outcome. In cases of tissue necrosis following trauma involving wound contact with soil (i.e., potential fungal contamination), testing for the presence of Zygomycetes fungi such as S. vasiformis in both immunocompetent and immunocompromised patients is crucial. The reason is that this infection usually has a rapid progression and may be fatal if appropriate treatment is not administered.

    Endemic deep fungal infections are still under recognised diseases in daily medical practice because of their rarity in sub-Saharan area. The African histoplasmosis Histoplasma capsulatum var. duboisii (H. capsulatum duboisii) is the most frequent variety described in Mali through limited studies in adult patients, since the first case described by Catanei and Kervran (1945). Our case report is a disseminated histoplasmosis in a young 6-year-old african child. He was male and rural. The infectious localisations were mucosae, skin, lymphnodes, urinary tract and bones. Evolution has been marred by an episode of worsening of symptoms despite initial clinical improvement with ketoconazole. After healing of mucocutaneous lesions, we noticed a limitation of ampliation of both wrists. The radiographic bone lesions were lysis of the right lower end of the right radius and cubitus and fragmentation of cubital epiphysis of the same arm. Lacunes were present on the fifth right finger in metatarsus and phalanx; lacune and blowing aspect of the second phalanx of the left third finger was noted. The disseminated form of African histoplasmosis may occur in HIV-negative subject. The prognosis depends on early diagnosis and administration of appropriate and well-conducted therapy.

    2011-11-01

    Full Text Available Abstract Type 1 hyper IgE syndrome (HIES, also known as Job's Syndrome, is an autosomal dominant disorder due to defects in STAT3 signaling and Th17 differentiation. Symptoms may present during infancy but diagnosis is often made in childhood or later. HIES is characterized by immunologic and non-immunologic findings such as recurrent sinopulmonary infections, recurrent skin infections, multiple fractures, atopic dermatitis and characteristic facies. These manifestations are accompanied by elevated IgE levels and reduced IL-17 producing CD3+CD4+ T cells. Diagnosis in young children can be challenging as symptoms accumulate over time along with confounding clinical dilemmas. A NIH clinical HIES scoring system was developed in 1999, and a more recent scoring system with fewer but more pathogonomonic clinical findings was reported in 2010. These scoring systems can be used as tools to help in grading the likelihood of HIES diagnosis. We report a young child ultimately presenting with disseminated histoplasmosis and a novel STAT3 variant in the SH2 domain.

    Sporotrichosis is a subacute or chronic granulomatous mycosis caused by fungus of the Sporothrix schenckii complex. It is considered to be a rare condition in most parts of the world. It mostly causes cutaneous infection but can also cause multisystemic disease. Unlike most deep cutaneous mycoses which have a primary pulmonary focus, it is usually caused by direct inoculation of the fungus into the skin causing a classical linear, lymphocutaneous nodular eruption. However, atypical presentations of the condition can occur especially in immunosuppressed individuals. We report the case of a severely immunosuppressed female who presented with disseminated cutaneous sporotrichosis which was initially diagnosed and treated as disseminated cutaneous Kaposi's sarcoma.

    Full Text Available Histoplasmosis is a systemic mycosis endemic in extensive areas of the Americas. The authors report on an urban adult male patient with uncommon oral-cutaneous lesions proven to be histoplasmosis. Additional investigation revealed unnoticed HIV infection with CD4+ cell count of 7/mm3. The treatment was performed with amphotericin B, a 2065 mg total dose followed by itraconazole 200mg/daily plus antiretroviral therapy with apparent cure. Histoplasmosis is an AIDS-defining opportunistic disease process; therefore, its clinical diagnosis must drive full laboratory investigation looking for unnoted HIV-infection.Histoplasmose é infecção sistêmica endêmica em extensas áreas do continente Americano. Os autores relatam caso de paciente do sexo masculino, de zona urbana com lesões cutâneas e mucosas incomuns de histoplasmose. Investigação adicional posterior revelou infecção subjacente pelo HIV com contagem de células CD4 de 7/mm3. O tratamento foi realizado com anfotericina B, dose total de 2065 mg, seguido por itraconazol 200 mg/dia associado à terapêutica antirretroviral com cura aparente do quadro. Histoplasmose é enfermidade oportunística definidora da síndrome de imunodeficiência adquirida, portanto, diagnóstico clinico de histoplasmose implica em investigação laboratorial de infecção subjacente pelo HIV.

    Two 6-month-old raccoon kits, which had been rescued and fostered in preparation for return to the wild, became acutely ill and died 3 weeks before scheduled release. At necropsy, the kits had grossly enlarged livers and spleens, diffusely consolidated lungs, and generalized lymphadenopathy. Histologically, extensive infiltrates of macrophages containing yeast organisms were identified in lung, liver, kidney, spleen, lymph nodes, intestinal tissues, brain, adrenal gland, bone marrow, and thymus of both animals. Histiocytic inflammation with accompanying fibrosis was widespread, with necrotic foci evident in lungs, spleen, and intestinal sections. Fungal organisms were observed on sheep blood agar plates; however, repeated subcultures to fungal media designed to induce conidial structures for fungal identification were unsuccessful. Partial DNA sequencing of the 28S ribosomal RNA gene of the blood agar isolate identified 100% homology with Ajellomyces capsulatus (anamorphic name Histoplasma capsulatum). The kits were rescued and fostered in the San Francisco Bay area and it is likely that the exposure to H. capsulatum occurred in this area. Histoplasma sp. infection in wild mammal species is often used as an indication of spore contamination of a geographic region. Northern California is not known to be an endemic region for H. capsulatum, which is not a reportable disease in this state. The presence of severe, disseminated disease and the need for molecular identification associated with the isolate from a nonendemic region identified in the present report may indicate genetic adaptation and altered characteristics of this agent and may warrant further investigation.

    Full Text Available Cryptococcosis is an opportunistic infection caused by a ubiquitous encapsulated yeast, Cryptococcus neoformans. Affects 5 – 10 % of patients with HIV worldwide. Disseminated cryptococcosis is one of the AIDS defining criteria and the most common cause of life threatening meningitis. Upto 20% of patients with disseminated disease can have skin involvement. Cutaneous lesions in disseminated cryptococcosis are seldom pathognomonic and portent neurological involvement. The significance of skin lesions may provide the first evidence of dissemination and indicate a poor prognosis, however, earlier recognition and treatment would improve survival. Herein we report a case of cryptococcal meningitis with skin lesions in a HIV seropositive patient.

    Full Text Available A 55 year old HIV negative, controlled diabetic, male suffering from recurrent oropharyngeal ulcer for last 4 years, has recently developed papules and nodules predominantly on face and a few on upper trunk, arms and macrochilia for about last 3 months. Some papules resembled molluscum contagiosum. His palms showed significant erythema. Multiple ulcerative nodules were visible on tongue and buccal mucosa. Histopathology revealed intracellular yeast of Histoplasma capsulatum by PAS stain. The patient had no involvement of internal organs. He never traveled to endemic area but had exposure to a domestic ‘moina’ bird for last 6 years. The subject responded well to oral itraconazole 400 mg daily for 8 weeks followed by a maintenance therapy with 200 mg daily for another 8 weeks.

    Full Text Available Case Report. A 47-year-old man presented with blurred vision in the right eye. Ophthalmoscopic examination showed several placoid, pigmented lesions in the posterior pole and midperiphery of the retina of both eyes. Results. Patient referred a cutaneous malignant melanoma on the back skin removed 6 years ago. A systemic workup revealed multiple metastases in liver and spleen. After an exhaustive study we concluded that it was a dissemination of a cutaneous malignant melanoma with bilateral choroidal metastases, liver and spleen metastases. The patient obtained clinical ocular improvement after palliative chemotherapy, although he died in the following months. Pathological examination of the lesions confirmed the diagnosis of choroidal metastases from a malignant cutaneous melanoma. Conclusions. Monitoring patients who have had cutaneous malignant melanoma is very important, since melanoma metastases may occur even many years after the diagnosis of the primary tumor. Choroidal metastases from cutaneous melanoma are uncommon but we should be aware because their appearance worsens prognosis.

Setting: A 600- bed, tertiary care hospital in New Delhi, India. Patient: A 53 years old diabetic male, presenting with acute respiratory failure, having received treatment for 2 weeks for acute bronchitis that included corticosteroids. He had a history of receiving several courses of treatment for Strongyloides stercoralis larvae detected in his stools. During this admission, he went on to develop neurological signs, cutaneous lesions and acute respiratory distress syndrome (ARDS. Negative stool examinations led to the diagnosis being delayed until the 7th day, when the larvae were demonstrated in the skin lesions and tracheal aspirate. Conclusion: Awareness of the varied presentations of Strongyloidiasis and a diligent search for the larvae at various sites are crucial for early diagnosis.

  9. Disseminated cutaneous sporotrichosis in a patient with AIDS: report of a case

    2002-01-01

    Full Text Available We describe a case report of disseminated cutaneous sporotrichosis as the initial presentation of AIDS in a 24-year-old HIV-positive male patient. He presented multiple ulcerated skin lesions distributed over the face, thorax, legs and arms. Biopsy of one of the cutaneous lesions was suggestive of sporotrichosis and culture isolated Sporothrix schenckii. Itraconazole was started and the lesions progressively resolved after 15 days of medication. The patient was discharged with this medication but he did not return for follow-up. He died three months later in another hospital. Therapy of sporotrichosis in HIV-infected patients remains unclear and the response to therapy is variable. Itraconazole is highly concentrated in the skin and is one of the options for treatment of disseminated sporotrichosis.

    Full Text Available Background. The outcome of neonates with congenital cutaneous Langerhans cell histiocytosis (LCH is variable. Observations. We report a case of LCH in a female premature neonate born at 33-week gestation. She had disseminated cutaneous lesions, which consisted of hemorrhagic papules and vesicles, with sparse healthy skin areas, and the hands and feet were contracted with scarring and blackened. She was in respiratory failure although no apparent pulmonary or bone lesions on X-rays were noted. Skin biopsy confirmed a diagnosis of LCH due to observation of CD1a+ Langerhans cells, which lacked expression of E-cadherin and CD56. The patient died 57 hours after birth. Conclusions. Based on this case and the literature survey, the outcome of premature babies with congenital cutaneous LCH lesions is noted to be unfavorable, with the majority of such cases suffering from multisystem disease.

    Leishmaniasis is emerging as a common and serious opportunistic disease for patients with HIV infection. Almost all cases of HIV-Leishmania coinfection have been described in Mediterranean countries and they occur with various clinical presentations, ranging from typical visceral forms to asymptomatic or atypical cases, including cutaneous and mucocutaneous leishmaniasis. Pentavalent antimony compounds have been the mainstays of antileishmanial therapy for half a century and new lipid formulations of amphotericin B seem reliable, but the most effective treatment remains unknown. We describe a patient who was HIV infected and an intravenous drug user, with an unusual disseminated cutaneous leishmaniasis, after an initial visceral disease and after a 13-month maintenance treatment with liposomal amphotericin. The severe concurrent immunosuppression probably played an essential role in leading to this atypical cutaneous form, characterized by diffuse, nonulcerated, nonscabby maculopapular lesions.

    We report a case of primary mucocutaneous histoplasmosis in an immunocompetent individual. The patient, a 61-year-old woman, presented with a non-healing ulcer on the lateral border of her tongue. Excisional biopsy of the lesion was consistent with histoplasmosis and no evidence of pulmonary or disseminated infection was found. Although mucocutaneous infection has been well-described as a manifestation of disseminated disease, especially in immunocompromised individuals, oral infections in immunocompetent patients are rare.

    Full Text Available Glomuvenous malformations (GVMs present as asymptomatic multiple pink-to-blue nodules or plaques. Disseminated lesions are rare, representing 10% of all the cases. Familial cases are caused by mutations in the glomulin gene. A young male presented with multiple bluish-to-dusky red-coloured nodules 10-15 in numbers over the trunk, limbs and buttocks since 12 years of age. They ranged in size from 1 to 3 cm, partially to non-compressible and tender on palpation. There was no history of any systemic complaint. His sister and mother had similar lesions but in a limited distribution. Biopsy showed multiple ectatic dilated vascular channels lined by multiple layers of glomus cells consistent with the diagnosis of GVM. The biopsy of the lesions from the mother and sister also showed similar features. Mutation analysis for glomulin gene could not be done because of the unavailability of the facility at our setting. He underwent sclerotherapy with 3% polidocanol every 2 weeks, and there was significant improvement in the lesions after six sessions of sclerotherapy. The patient is under follow-up and there is no recurrence of the lesions over treated sites after 6 months.

    Full Text Available Little is known regarding the internal dissemination of initial cutaneous lesions and tissue tropism of Leishmania (Viannia braziliensis populations in naturally infected dogs. The aim of this study was to investigate genetic polymorphisms of L. (V. braziliensis populations in different anatomic sites of naturally infected dogs by using polymerase chain reaction (PCR and low-stringency single specific primer-PCR (LSSP-PCR techniques. The amplified products were analyzed by LSSP-PCR to investigate the genetic variability of the parasite populations present in different anatomical sites. Twenty-three out of the 52 samples gave PCR-positive results. The existence of L. (V. braziliensis strains that remained restricted to cutaneous lesions and others showing characteristics of dissemination to internal organs and healthy skin was observed. LSSP-PCR and numerical analyses revealed that parasite populations that do not disseminate were genetically similar and belonged to a separate phenetic cluster. In contrast, populations that showed spreading to internal organs displayed a more polymorphic genetic profile. Despite the heterogeneity, L. (V. braziliensis populations with identical genetic profiles were observed in popliteal and cervical lymph nodes of the same animal. Our results indicate that infection in dogs can be manifested by dissemination and tissue tropism of genetically distinct populations of L. (V. braziliensis.

    Directory of Open Access Journals (Sweden)

    Venkatachalam

    2015-11-01

    Full Text Available Sporotrichosis is a sub-acute or chronic fungal infection caused by the ubiquitous fungus Sporothrix schenckii. Disseminated sporotrichosis is an uncommon entity and is usually present in the immunosuppressed. Here, a case of disseminated sporotrichosis in an immune competent patient is reported. This 50-year-old woman presented with multiple painful ulcers on her upper and lower extremities of 10 months’ duration, associated with low-grade fever, night sweats, loss of appetite, and loss of weight. Histopathological examination of the skin biopsy revealed epidermal hyperplasia and granulomatous inflammation in the dermis with budding yeast. Fungal culture identified S. Schenckii. All investigations for underlying immunosuppression and internal organ involvement were negative. This case reiterates that disseminated cutaneous sporotrichosis, although common in the immunosuppressed can also be seen in immunocompetent.

    Histoplasmosis is a granulomatous disease of worldwide distribution caused by a dimorphic fungus Histoplasma capsulatum. Majority of primary infections in immunocompetent hosts are asymptomatic or may present with flu-like illness. Histoplasmosis may occur in three forms: (i) Primary acute pulmonary form, (ii) chronic pulmonary and (iii) disseminated form. The manifestations of disseminated form of histoplasmosis are fever, weakness, weight loss, hepatosplenomegaly, and mucocutaneous lesions. The mucosal involvement could be oropharyngeal or laryngeal involvement. We report an unusual case of histoplasmosis presenting as a laryngeal ulcer in an immunocompetent host.

    Disseminated histoplasmosis in South America is associated with AIDS in 70-90 % of cases. It is visceral and cutaneous, compromising the oral, pharynx, and laryngeal mucous membranes. The involvement of the nasal mucosa is unusual. Two patients with perforation of the nasal septum as the only sign of their disease were clinically and histopathologically diagnosed as leishmaniasis. The revision of the biopsies and the culture of nasal discharge secretions showed that the pathogens seen were not amastigotes but Histoplasma capsulatum. Other mycotic lesions were not detected, nor there was history of cutaneous leishmaniasis. The leishmanin skin test, available only for the male patient, was negative. The PCR and immunofluorescence antibody titers for Leishmania were negative in both patients. They were HIV positive; in the male, his CD4+ T cell count was 60/mm(3) and in the female 133/mm(3). The nasal ulcer was the only manifestation of histoplasmosis and the first of AIDS in both patients. The male patient recovered with amphotericin B and itraconazole treatment. The female has improved with itraconazole. Both patients received antiretroviral treatment. Nasal mucous membrane ulcers should include histoplasmosis among the differential diagnosis. In conclusion, two patients had perforation of their nasal septum as the only manifestation of histoplasmosis, a diagnosis confirmed by nasal mucosa biopsy and by culture of H. capsulatum, findings which demonstrated that both patients had AIDS.

    Full Text Available Sporotrichosis is an implantation or inoculation mycosis caused by species of Sporothrix schenckii complex; its main manifestations are limited to skin; however, cutaneous-disseminated, disseminated (visceral and extracutaneous variants of sporotrichosis can be associated with immunosuppression, including HIV-AIDS, chronic alcoholism or more virulent strains. The most common extracutaneous form of sporotrichosis includes pulmonary, osteoarticular and meningeal. The laboratory diagnosis requires observing yeast forms and isolating the fungus; the two main causative agents are Sporothrix schenckii (ss and Sporothrix brasiliensis. Antibody levels and species recognition by Polimerase Chain Reaction using biological samples or cultures are also useful. The treatment of choice for most cases is amphotericin B and subsequent itraconazole for maintenance therapy.

    Histoplasmosis is a cosmopolitan mycosis caused by Histoplasma capsulatum. It is endemic of Río de la Plata's riverbed and in immunocompromised patients may be deadly. We present two patients with Human Immunodeficiency Virus diagnosed with subacute disseminated histoplasmosis, which is a marker of Acquired Human Immunodeficiency Syndrome. This situation increases the morbimortality, thus forcing clinicians to diagnose and treat rapidly in order to avoid fatal outcomes.

    Cryptococcosis is a fungal infection caused by Cryptococcus neoformans that tends to affect immunocompromised individuals. The fungi are mostly acquired by inhalation, which leads to an initial pulmonary infection. Later, other organs - such as the central nervous system and the skin - can be affected by hematogenous spread. In addition, cutaneous contamination can occur by primary inoculation after injuries (primary cutaneous cryptococcosis), whose diagnosis is defined based on the absence of systemic involvement. The clinical presentation of cutaneous forms typically vary according to the infection mode. We report an unusual case of disseminated cryptococcosis in an immunocompetent patient with cutaneous lesions similar to those caused by primary inoculation. This clinical picture leads us to question the definition of primary cutaneous cryptococcosis established in the literature. PMID:28300886

    2017-07-01

    Full Text Available We present a case of an immunocompetent 27-year-old African American man who was initially diagnosed with diffuse pulmonary coccidioidomycosis and started on oral fluconazole. While his symptoms improved, he began to develop tender cutaneous lesions. Biopsies of the cutaneous lesions grew Coccidioides immitis. Subsequent 18F-FDG PET/CT revealed extensive multisystem involvement including the skin/subcutaneous fat, lungs, spleen, lymph nodes, and skeleton. This case demonstrates the utility of obtaining an 18F-FDG PET/CT to assess the disease extent and activity in patients with disseminated coccidioidomycosis who initially present with symptoms involving only the lungs.

    Endemic deep or systemic mycoses are common in specific geographical areas of the world. Coccidioidomycosis is present in semi-desert areas, histoplasmosis and paracoccidioidomycosis in tropical regions and blastomycosis belongs to temperate climates. The two former are widely distributed in the American continent and some tropical regions of the world; the third is limited to Central and South America, and the last to North America and Central and East Africa. These mycoses all have a similar pathogenesis, as the inoculum enters the host through the respiratory tract. Cutaneous manifestations are secondary to lymphatic and hematogenous dissemination. These deep mycoses are exceptional in Europe. Most cases are observed in returning travelers from endemic areas, aid workers, archaeologists, speleologist and immigrants. However, there have been some autochthonous cases of histoplasmosis due to Histoplasma capsulatum var. capsulatum reported in European countries such as Italy and Germany. In this article, we provide up-to-date epidemiological, clinical, diagnostic and therapeutic data on the four most important imported systemic mycoses in Europe.

    Nancy A. Rihana

    2014-01-01

    Full Text Available Background. Histoplasma capsulatum is the most common endemic mycosis in the United States and is a frequent cause of opportunistic infection in immunodeficient hosts. Histoplasmosis is most often self-limiting and goes unrecognized in the immunocompetent population but can progress to disseminated histoplasmosis in patients with an impaired immune system. Liver involvement as a part of disseminated histoplasmosis which usually originates in the lung is well known. However, extrapulmonary hepatic histoplasmosis as a primary manifestation is extremely rare. Case Presentation. We report a rare case of histoplasmosis that presented as persistent fever and abnormal liver function tests in a 66-year-old female with rheumatoid arthritis, receiving infliximab. Conclusion. Emphasizing histoplasmosis as a major cause of acute granulomatous hepatitis and fever of unknown origin in cell mediated immunodeficient population, this case highlights the need for high index of suspicion and the importance of prompt diagnosis since any delay of treatment can be life threatening in this population.

    Invasive disseminated neonatal aspergillosis is an uncommon disease, with only scattered reports in literature in the last few years. Here we report on a 25-week gestational age, 730 g at birth preterm female infant who developed on day-of-life 10 multiple cutaneous exhulcerative lesions in her right arm, trunk and abdomen. Early recognition and diagnosis of these lesions as a due to cutaneous initial symptom of cutaneous disseminated aspergillosis, as well as prompt treatment with Liposomal amphotericin B + Itraconazole, secured successful recovery from the systemic infection. Skin lesions healed without any surgical treatment. The infant was discharged in good health. Long-term follow-up at three years of age revealed normality of all neurodevelopmental and cognitive parameters. To our knowledge, this is one of the very few cases of survival, free from sequelae, for a preterm infant affected by neonatal cutaneous disseminated aspergillosis.

    Histoplasmosis occurs in specific endemic areas, including the mid-western United States, Africa and most of Latin America. Sporadic cases have also been reported in China. The aim of this study was to summarise the epidemiological and clinical data of histoplasmosis in China. We searched the PubMed, CBMdisk and CNKI databases to identify publications related to histoplasmosis in China. Case reports/series on patients with histoplasmosis were included. A comprehensive literature review identified additional cases. The relevant material was evaluated and reviewed. Overall, 300 cases of histoplasmosis were reported in China from 1990 to 2011, and 75% were from regions through which the Yangtze River flows. Most of the patients were autochthonous infections. Of these, 43 patients had pulmonary histoplasmosis and 257 patients had disseminated histoplasmosis. Common underlying diseases included HIV infection, diabetes mellitus and liver diseases. Fever was the most frequently reported clinical feature in disseminated histoplasmosis, followed by splenomegaly and hepatomegaly. Cases of histoplasmosis had a prominent geographical distribution in China. Histoplasmosis should be considered in the diagnosis of patients with relevant symptoms and a history of travel to or residence in these areas.

We report the clinical and imaging findings in a case of a child with the rare presentation of a neck abscess and mediastinal lymphadenopathy secondary to acute, non-disseminated histoplasmosis. Imaging findings often mimic other granulomatous infections such as tuberculosis or neoplastic processes such as lymphoma. Histoplasmosis should be considered in the differential diagnosis of a child who presents with enlarged mediastinal and cervical lymphadenopathy. (orig.)

    Full Text Available INTRODUCTION: Histoplasmosis is a systemic mycosis endemic in Brazil, especially in the State of Rio Grande do Sul, where Histoplasma capsulatum was isolated from the soil. H. capsulatum may compromise unusual areas, including the oropharynx, particularly in patients presenting disseminated histoplasmosis; which is associated with a state of immunosuppression, such as AIDS. METHODS: During database analysis of a total of 265 cases of histoplasmosis, the medical records of 11 patients with histological or microbiological diagnoses of oral histoplasmosis (OH between 1987 and 2008 were retrospectively reviewed. RESULTS: This work reports 11 cases of OH, the majority presenting histopathological or microbiological evidence of disseminated histoplasmosis (DH. In the patients with DH, OH was the first manifestation of histoplasmosis. Five of the 11 patients discussed were HIV-seropositive with clinical and laboratory findings of AIDS. Four patients presented active pulmonary tuberculosis concomitant with histoplasmosis. Treatment was based on the use of itraconazole and amphotericin B deoxycholate. Eight patients responded successfully to therapy after one year, two did not come back for reevaluation and one died despite adequate therapy. CONCLUSIONS: Oral histoplasmosis is closely associated with immunosuppression status, especially in patients presenting AIDS; moreover, in many cases, OH is the first sign of disseminated histoplasmosis.

    We report four disseminated cutaneous leishmaniasis(DCL) cases referred to leishmaniasis laboratory at the School of Public Health, Tehran University of Medical Sciences with multiple nodular, ulcerative and crusted lesions extended on the face, trunk, and extremities. None of the patients had any complication and historical involvement in their immunological system conditions that suggest as the criteria for DCL. Direct smears of ulcers were positive for Leishmania parasite. The parasite was isolated from the active lesions and identified as Leishmania major (L. major) using PCR-RFLP assay and sequencing analysis.

    Sporotrichosis is a subacute or chronic infection caused by Sporothrix schenckii. It is a primary cutaneous infection and it has different clinical forms: disseminated by lymphatic vessels (75%), localised cutaneous form (20%), disseminated cutaneous and extracuteus rarely. The systemic disseminated sporotrichosis is considered a severe opportunistic infection. The best diagnostic test is the culture. The authors report a case of a 36-year-old man, originally from Puebla, Mexico, with a diagnosis of disseminated sporotrichosis. Differential diagnosis with other pathologies includes leishmaniasis, chromoblastomycosis, tuberculosis verrucose and lymphangitis. The development of unusual presentations in immunocompromised patients has been reported.

    Objective To summarize the characteristics of intestinal lesions in 3 cases of immunocompetent host with dis-seminated histoplasmosis. Methods Retrospective analysis of clinical and endoscopic features was carried out in 3 cases of im-munocompetent host with disseminated histoplasmosis during 2005 and 2014 at our hospital. Results Fever,abdominal pain, dis-tention,hepatosplenomegaly,lymphadenopathy are the most common nonspecific symptoms and signs. Lesions which involving the colon and terminal ileum were manifested as diffuse or segmental mucosal nodular with or without erosion,shallow ulcers. The con-firmed diagnosis depended on multiple site biopsy and pathogenic culture. All patients were treated with amphotericin B deoxy-cholate and Itraconazole,it was effective in 2cases while the other one were lost to follow-up. Conclusion This rare disease is easy to be misdiagnosis. Gastrointestinal physicians should pay attention to the characteristics,biopsy and pathogen culture should be done if lesions had been found.%目的:探讨累及免疫正常宿主肠道的播散型组织胞浆菌病临床及内镜下特点、诊治及转归。方法对四川大学华西医院2005至2014年诊治的3例累及肠道的播散型组织胞浆菌病进行回顾性分析,总结患者的临床及内镜下特点、治疗及转归。结果临床表现无特异性,主要为发热、腹痛、腹胀等症状;肝脾肿大、浅表或深部淋巴结肿大等为常见体征。病程3~7月,确诊时间8~26d。3例均为免疫正常患者,累及结肠多部位及末段回肠,表现为弥漫或节段性的粘膜结节样隆起,伴或不伴糜烂、浅溃疡形成。所有患者均多部位活检、经病原学培养确诊。使用两性霉素B、伊曲康唑抗真菌治疗,2例痊愈,1例自动出院,失访。结论累及免疫正常宿主肠道的播散型组织胞浆菌病较少见,极易误诊漏诊,临床及内镜医师应重视内镜下病变表现特点,进行活检及病原学培养。

    To investigate the predictive and prognostic value of O(6) -methylguanine DNA methyltransferase (MGMT) inactivation by analyses of promoter methylation in pretreatment tumor biopsies from patients with cutaneous melanoma treated with dacarbazine (DTIC) or temozolomide (TMZ) were performed. The patient cohorts consisted of Belgian and Swedish disseminated melanoma patients. Patients were subdivided into those receiving single-agent treatment with DTIC/TMZ (cohort S, n = 74) and those treated with combination chemotherapy including DTIC/TMZ (cohort C, n = 79). Median follow-up was 248 and 336 days for cohort S and cohort C, respectively. MGMT promoter methylation was assessed by three methods. The methylation-related transcriptional silencing of MGMT mRNA expression was assessed by real-time RT-PCR. Response to chemotherapy and progression-free survival (PFS) and overall survival were correlated to MGMT promoter methylation status. MGMT promoter methylation was detected in tumor biopsies from 21.5 % of the patients. MGMT mRNA was found to be significantly lower in tumors positive for MGMT promoter methylation compared to tumors without methylation in both treatment cohorts (p MGMT promoter methylation in cohort S (p = 0.0005), but did not reach significance in cohort C (p = 0.16). Significantly longer PFS was observed among patients with MGMT promoter-methylated tumors (p = 0.002). Multivariate Cox regression analysis identified presence of MGMT promoter methylation as an independent variable associated with longer PFS. Together, this implies that MGMT promoter methylation is associated with response to single-agent DTIC/TMZ and longer PFS in disseminated cutaneous melanoma.

    Histoplasmosis is a fungal infection caused by Histoplasma capsulatum and is distributed a worldwide. Although the disease has been treated as an imported mycosis, some autochthonous human, 1 equine and 4 canine cases suggested that the disease is endemic. Histoplasmosis is classified depending on the variety of causative agent. Histoplasmosis farciminosi known as pseudofarcy, is manifested only in Perissodactyla where it invades lymph nodes and lymph ducts, and is recognized by isolation from horses. Historically, Japan was one of the endemic areas of pseudofarcy before World War II, and more than 20,000 cases were recorded in horses used by the military. Interestingly, Japanese canine histoplasmosis uniformly showed skin ulcers and granulomatous lesions on the skin without pulmonary or gastrointestinal involvement, both of which were very similar to pseudofarcy. It was diagnosed as histoplasmosis by the detection of internal transcribed spacer legions of rRNA gene of H. capsulatum from paraffin embedded tissue samples. Furthermore, the fungal isolate from the human case with no history of going abroad or immigrating was identified as H. capsulatum var. farciminosum by a gene sequence. These facts indicated that pseudofarcy is not only an infectious disease in horses, but also a zoonotic fungal infection. Japanese autochthonous canine histoplasmosis might be a heteroecism of pseudofarcy because of its likeness to the human case, the similarity of clinical manifestations and the historical background at this stage.

  7. NF- κB Essential Modulator Deficiency Leading to Disseminated Cutaneous Atypical Mycobacteria

    2014-12-01

    Full Text Available NF- κB essential modulator (NEMO is a kinase integral to the macrophage TNF-α pathway, which leads to the intracellular destruction of Mycobacteria species. Defects in the NEMO pathway lead to a spectrum of diseases, including but not limited to ectodermal dysplasia, Mendelian susceptibility to mycobacterial diseases, and incontinentia pigmenti. In addition, paucity of NEMO can lead to the inability to mount a proper immune response against opportunistic pyogenic and mycobacterial infections, leading to dissemination to various organ systems. This manuscript will discuss the numerous clinical manifestations of NEMO deficiency, the differential diagnosis for atypical mycobacterial infections in immunocompetent adults, and feature a case report of rare isolated susceptibility to disseminated atypical mycobacteria due to a mutation in the first exon of the NEMO gene.

    Histoplasmosis has emerged as an important opportunistic fungal infection in immunocompromised patients. Histoplasma is a dimorphic fungus that primarily involves lung and the environmental reservoir is soil. Although several cases of histoplasmosis have been reported in India but cytological diagnosis was made in a few cases. We are presenting two cases of histoplasmosis diagnosed on fine-needle aspiration cytology. In the first case, pulmonary histoplasmosis was diagnosed on transbronchial needle aspiration of lung in a 41-year-old immunocompetent male, while second case was of disseminated histoplasmosis in 40-year-old immunocompromised female diagnosed on cytology of cervical lymph node. FNAC is a simple, safe, and rapid technique to establish the initial diagnosis, thus promoting early treatment and favorable outcome especially in the immunocompromised patients.

    Histoplasmosis is a common endemic human mycoses acquired mostly in the Americas. We reviewed 23 cases of histoplasmosis in Israeli travelers; 22 had traveled to Central or South America and one to North America. Fourteen cases had been exposed to bat habitats and were symptomatic, presenting ≤ 3 months after their return. Asymptomatic patients (N = 9) were diagnosed during the evaluation of incidental radiological findings or because a travel partner had been suspected of Histoplasma infection, 16-120 months after their return. Serological testing was positive in 75% of symptomatic cases but only 22% of asymptomatic cases. Histoplasmosis should be considered in travelers returning from the Americas with respiratory or febrile illness within weeks of return, particularly if exposed to bat habitats. Travel history is essential in patients presenting with pulmonary nodules, even years after travel to endemic countries.

    Full Text Available Biopsies from human localized cutaneous lesions (LCL n = 7 or disseminated lesions (DL n = 8 cases were characterized according to cellular infiltration,frequency of cytokine (IFN-g, TNF-alpha or iNOS enzyme producing cells. LCL, the most usual form of the disease with usually one or two lesions, exhibits extensive tissue damage. DL is a rare form with widespread lesions throughout the body; exhibiting poor parasite containment but less tissue damage. We demonstrated that LCL lesions exhibit higher frequency of B lymphocytes and a higher intensity of IFN-gamma expression. In both forms of the disease CD8+ were found in higher frequency than CD4+ T cells. Frequency of TNF-alpha and iNOS producing cells, as well as the frequency of CD68+ macrophages, did not differ between LCL and DL. Our findings reinforce the link between an efficient control of parasite and tissue damage, implicating higher frequency of IFN-gamma producing cells, as well as its possible counteraction by infiltrated B cells and hence possible humoral immune response in situ.

    Full Text Available Lyme disease (LD is a tick-borne illness caused by Borrelia burgdorferi sensu stricto. An 80-year-old female from Pennsylvania, USA, presented to an outside hospital with fever, confusion, lower extremity weakness, and stool incontinence. CT head and MRI spine were unremarkable. An infectious work-up including lumbar puncture was negative. She was transferred to our tertiary care hospital. Patient was noted to have mild unilateral right-sided facial droop and a diffuse macular rash throughout the body. She denied any outdoor activities, tick bites, or previous rash. Intravenous ceftriaxone was started for suspected LD. The patient’s symptoms including facial droop resolved within 24 hours of antibiotic therapy. Polymerase chain reaction of the blood, IgM ELISA, and IgM Western blot testing for LD came back positive a few days after initiation of therapy. She was treated for a total of 21 days for neurological LD with complete symptom resolution. Not all patients have the classic “targetoid” EM rash on initial presentation, rash could develop after neurological manifestations, and prompt initiation of antibiotics without awaiting serology is paramount to making a quick and a full recovery. There should be a high index of suspicion for early disseminated LD, as presentations can be atypical.

    Untreated histoplasmosis is life threatening, especially in immunosuppressed patients. In French Guiana, South America, it is one of the most common opportunistic infections in AIDS patients. Twenty-one cases of disseminated histoplasmosis were diagnosed in 2004 in the mycology laboratory of Cayenne hospital. Culture samples for histoplasmosis diagnosis is simple, sensitive, and specific, but it is a lengthy process. Management of the disease is then dangerously delayed. In this work, we tested a polymerase chain reaction (PCR) method on 40 samples from patients with suspected disseminated histoplasmosis. The recently described Hcp100 nested PCR method was used to detect Histoplasma capsulatum DNA in these samples. All of the positive cultures for H. capsulatum were also positive with PCR method. Tested on other fungi or negative culture, it also showed high specificity. Furthermore, it allows treating patients more rapidly. Culture remains necessary, but histoplasmosis PCR offers great prospects, on a clinical point of view.

The patient in this case was asymptomatic and without previous illness. An ecographic study revealed an enlarged right adrenal gland, 66 by 33 mm. CT showed bilateral irregular enlargement of both adrenal glands. Nonadrenal malignancies and hyperfunctioning tumors were ruled out. A CT-guided biopsy was performed, and the histopathologic study was consistent with the diagnosis of histoplasmosis. The patient lived in an area endemic for this disease, and had daily contact with bird droppings. Histoplasmosis is a rare unsuspected cause of bilateral adrenal masses in the asymptomatic immunocompetent host.

    In Western French Guiana, there was a dramatic increase in HIV prevalence between 1990 and 2000. The present study describes the causes of fever among HIV patients hospitalized in the medical ward of the only hospital in the western part of French Guiana. A retrospective descriptive study was conducted between 1 January 2008 and 30 June 2010 in the department of medicine of Saint Laurent du Maroni Hospital. The main characteristics of 67 patients having presented with fever in the first 48 hours of hospitalization were described. Among patients with CD4 histoplasmosis (41.1%). Among patients with CD4 counts histoplasmosis. Three patients died and all had disseminated histoplasmosis. Disseminated histoplasmosis is the most common febrile opportunistic infection in western French Guiana. Primary prophylaxis with itraconazole among immunocompromised patients seems warranted.

    2008-08-01

    Full Text Available Abstract Introduction We present the case of a 49-year-old woman with a seronegative rheumatoid arthritis who developed pustular psoriasis whilst on etanercept and subsequently developed disseminated herpes simplex on infliximab. Case presentation Our patient presented with an inflammatory arthritis which failed to respond to both methotrexate and leflunomide, and sulphasalazine treatment led to side effects. She was started on etanercept but after 8 months of treatment developed scaly pustular lesions on her palms and soles typical of pustular psoriasis. Following the discontinuation of etanercept, our patient required high doses of oral prednisolone to control her inflammatory arthritis. A second biologic agent, infliximab, was introduced in addition to low-dose methotrexate and 15 mg of oral prednisolone. However, after just 3 infusions of infliximab, she was admitted to hospital with a fever, widespread itchy vesicular rash and worsening inflammatory arthritis. Fluid from skin vesicles examined by polymerase chain reaction showed Herpes Simplex Virus type 1. Blood cultures were negative and her chest X-ray was normal. Her infliximab was discontinued and she was started on acyclovir, 800 mg five times daily for 2 weeks. She made a good recovery with improvement in her skin within 48 hours. She continued for 2 months on a prophylactic dose of 400 mg bd. Her rheumatoid arthritis became increasingly active and a decision was made to introduce adalimumab alongside acyclovir. Acyclovir prophylaxis has been continued but the dose tapered so that she is taking only 200 mg of acyclovir on alternate days. There has been no recurrence of Herpes Simplex Virus lesions despite increasing adalimumab to 40 mg weekly 3 months after starting treatment. Conclusion We believe this to be the first reported case of widespread cutaneous Herpes Simplex Virus type 1 infection following treatment with infliximab. We discuss the clinical manifestations of Herpes

    Computed tomography (CT) of the adrenal glands was performed on seven patients who had histologically proved disseminated histoplasmosis. All seven patients showed some degree of adrenal gland abnormality. The range of CT findings included minimal enlargement with faint flecks of calcium, moderate enlargement with focal low attenuation nodules, and massive enlargement with large areas of necrosis or dense calcification. The changes in each patient were bilateral and symmetrical. Adrenal gland shape was usually preserved. Finding of percutaneous adrenal biopsy, which was performed under CT guidance, made the diagnosis in one patient. Five of seven patients had adrenal insufficiency. It is concluded that the diagnosis of disseminated histoplasmosis should be considered in any patient who has bilateral adrenal gland enlargement and who resides in an endemic area, especially if there is evidence of adrenal insufficiency.

    Histoplasmosis is the most common endemic mycosis in the North America, Central America, and many countries of South America and also occurs in China, India, Southeast Asia, Africa, Australia, and Europe. Clinical syndromes are not specific and histoplasmosis often is overlooked in the evaluation of patients with community-acquired pneumonia, chronic cavitary pneumonia resembling tuberculosis or anaerobic infection, granulomatous inflammatory diseases such as sarcoidosis or Crohn disease, and malignancy. The diagnosis depends on understanding the geographic distribution, common clinical presentations, and tests used for diagnosis of histoplasmosis. While histoplasmosis resolves without treatment in most patients, treatment is indicated in all immunocompromised patients and those with progressive disseminated disease or chronic pulmonary disease. Treatment is appropriate in most patients with acute pulmonary disease but rarely in those with other pulmonary or mediastinal manifestations. The preferred agents include liposomal amphotericin B for more severe cases and itraconazole for milder cases and "step-down" therapy following response to amphotericin B.

    Disseminated histoplasmosis is a relatively common AIDS-defining illness, occurring in almost 4% of patients living in endemic areas and it may be the first clinical expression of the HIV infection. A broad spectrum of clinical skin lesions associated with Histoplasma capsulatum infection have been described in AIDS patients, such as erythematous macules, papules, nodules, and pustules. Herpetic, acneiform, erythema multiforme-like, molluscum contagiosum-like, vasculitic, and exfoliative forms have also been reported. To our knowledge, this is the first case of disseminated histoplasmosis in an AIDS patient presented as a rupioid eruption.

    Full Text Available Introduction The distribution of infection by Histoplasma capsulatum in Brazil is heterogeneous, and the number of cases affecting immunocompetent individuals is relatively small. This study reports the epidemiological and clinical data regarding histoplasmosis in non-immunosuppressed individuals. Methods The study included only the immunocompetent patients with histoplasmosis who were diagnosed between 1970 and 2012 at a university hospital located in Ribeirão Preto, State of São Paulo, Brazil. Clinical and epidemiological data were collected retrospectively from the patient records. Results Of the 123 patients analyzed, 95 had an active disease that manifested in the different clinical forms of histoplasmosis. Men were the predominant gender, and most patients resided in the Northeast of the State of São Paulo and in the nearby municipalities of the State of Minas Gerais. The risk factors for acquiring histoplasmosis and prolonged contact in a rural environment were recorded in 43.9% and 82.9% of cases, respectively. Smoking, alcoholism, and comorbidity rates were high among the patients with the chronic pulmonary and subacute/chronic disseminated forms of histoplasmosis. Many patients achieved clinical cure spontaneously, but 58.9% required antifungals; the disease lethality rate was 5.3%. Conclusions Immunocompetent individuals manifested the diverse clinical forms of histoplasmosis over a period of 4 decades, revealing an additional endemic area of this fungal disease in the Brazilian Southeast.

    Histoplasmosis is a multifaceted condition caused by the dimorphic fungi Histoplasma capsulatum whose infective spores are inhaled and reach the lungs, the primary organ of infection. The meningeal form, considered one of the most serious manifestations of this mycosis, is usually seen in individuals with impaired cellular immunity such as patients with acquired immunodeficiency syndrome, systemic lupus erythematous or solid organ transplantation, and infants given their immunological immaturity. The most common presentation is self-limited and occurs in immunocompetent individuals who have been exposed to high concentrations of conidia and mycelia fragments of the fungi. In those people, the condition is manifested by pulmonary disorders and late dissemination to other organs and systems. We report a case of central nervous system histoplasmosis in an immunocompetent child.

    2015-01-01

    Ocular histoplasmosis syndrome (OHS) is a chorioretinal disorder with a distinct fundus appearance that is commonly found in regions endemic for Histoplasma capsulatum. Choroidal neovascularization (CNV) secondary to OHS is considered one of the principal causes of central vision loss among young adults in endemic areas. Although there is no consensus regarding its pathogenesis, evidence points to Histoplasma capsulatum as the most probable etiology. Once considered an intractable hemorrhagic maculopathy, CNVs are now treatable. Extrafoveal CNVs are successfully treated with laser photocoagulation. Subfoveal and juxtafoveal CNVs are managed with anti-vascular endothelial growth factor therapy, photodynamic therapy, or a combination of both. Modern imaging technologies such as spectral-domain optical coherence tomography have improved our diagnostic abilities, making it easier to monitor disease activity and CNV regression. We review the epidemiology, pathogenesis, clinical manifestations, differential diagnosis, and current treatment of this disease.

    In disease-endemic areas, histoplasmosis is the main differential diagnosis for tuberculosis among human immunodeficiency virus (HIV)-infected patients. However, no study has compared the two diseases. Thus, the objective of this study was to compare tuberculosis and histoplasmosis in HIV-infected patients. A population of 205 HIV-infected patients (99 with tuberculosis and 106 with histoplasmosis) hospitalized in Cayenne, French Guiana during January 1, 1997-December 31, 2008 were selected retrospectively from the French Hospital Database on HIV. Multivariate analysis showed that tuberculosis was associated with cough (adjusted odds ratio [AOR] = 0.20, 95% confidence interval [CI] = 0.05-0.73) and a C-reactive protein level > 70 mg/L (AOR = 0.98, 95% CI = 0.97-0.99). Variables associated with disseminated histoplasmosis were a γ-glutamyl transferase level > 72 IU/L (AOR = 4.99, 95% CI = 1.31-18.99), origin from French Guiana (AOR = 5.20, 95% CI = 1.30-20.73), disseminated localization (AOR = 6.40, 95% CI = 1.44-28.45), a concomitant opportunistic infection (AOR = 6.71, 95% CI = 1.50-29.96), a neutrophil count histoplasmosis have similarities, but some factors show a greater association with one of these diseases. Thus, adapted therapeutic choices can be made by using simple clinical and paraclinical criteria.

    Histoplasmosis is a rare disease caused by inhalation of the fungus Histoplasma capsulatum. It can spread via cerebral circulation to the central nervous system as a manifestation of a disseminated infection; particularly in patients with immune suppression, which can result in isolated ring-enhancing lesions and inflammation in the brain. Of the reported disseminated histoplasmosis cases (approximately 1 in 2000 per year), only 5-20% have evidence of central nervous system involvement. This paper reviews a single case study of a 57-year-old female diagnosed with disseminated CNS histoplasmosis. Patient's complaints included reduced short-term memory, word-finding problems, and difficulty organizing, making decisions, getting lost while driving, recalling names, retaining information while reading, and slowed processing speed. There was also a history of mild depression and anxiety. Direct testing revealed deficits in multiple cognitive domains including complex attention, processing speed, semantic fluency, visual scanning, motor speed, set-shifting, naming, nonverbal memory, and verbal memory. Neuropsychological deficits suggest cortical and subcortical brain dysfunction, including anterior, temporal, and mesial-temporal regions. This case illustrates the need for neuropsychologists to understand histoplasmosis, the related pathophysiology, and the neuropsychological impact; particularly with the potential for delayed progression.

    Histoplasmosis is a rare systemic fungal infection, primarily affecting the pulmonary system. Oral lesions are usually a manifestation of the disseminated form of the disease and most frequently observed in severely immunocompromised patients, such as those with advanced human immunodeficiency virus infection and/or frank acquired immune deficiency syndrome. The clinical presentation of the oral lesions may be difficult to distinguish from oral squamous cell carcinoma. The histopathological features are usually characteristic, but occasionally the organisms are scanty and not readily identified, which can preclude obtaining the correct diagnosis and ensuring appropriate management. Histoplasmosis is an unusual and rare cause of chronic non-healing ulceration in the oral cavity. A case of histoplasmosis involving the oral cavity in an immunocompetent patient is reported, which was not recognized, resulting in the inappropriate management of the condition.

    Full Text Available Histoplasmosis is a systemic mycosis caused by inhalation of Histoplasma capsulatum microconidia. The disease does not normally affect immunocompetent individuals after a single, transient inhalation exposure. However, longer exposure may cause chronic or disseminated acute pulmonary infection. Herein, we report the case of a 24-year-old immunocompetent patient, who presented fever, cough and dyspnea for one month. The chest radiography revealed interstitial infiltrate and diffuse micronodules. The patient reported having had close and prolonged contact with bats. Diagnosis was confirmed by positive double immunodifusion and immunoblotting assays. She was treated with ketoconazole (400 mg and there was complete resolution of the disease.

    Histoplasmosis is the second most common fungal infection reported in the cat. The disseminated form involving lung, liver, lymph nodes, spleen, and bone marrow is a frequent manifestation of the disease. Limited information is available in the literature regarding the ultrasonographic appearance of the spleen in cats with disseminated or splenic histoplasmosis. A retrospective review of splenic ultrasound images from 15 cats confirmed to have histoplasmosis by splenic aspirates was performed. Size, echotexture, echogenicity, margin appearance, presence of nodules, and the overall shape of the spleen were reported in each case. Splenomegaly was documented in all cases (15/15) and a hypoechoic appearance of the spleen was documented in 14/15 of cases. The spleen was diffusely and uniformly affected in 14/15 (six homogenous and eight with a subtle mottled appearance) and had discrete nodules in 1/15 cats. Histoplasmosis should be included in the differential list for an enlarged and hypoechoic spleen in cats with consistent clinical findings. Additionally, ultrasound guided splenic aspirate may be a useful method to obtain a cytology sample for diagnosis.

    The performance characteristics of the recently available analyte-specific reagent based enzyme immunoassay (ASR-EIA) and in vitro diagnostic (IVD) kit for urine Histoplasma antigen detection were evaluated in a cohort of 50 clinically characterized patients with histoplasmosis and 50 control patients. Overall sensitivity and specificity of the ASR-EIA were significantly improved compared with those of the IVD kit (sensitivity 72% vs. 22%, Phistoplasmosis (five with pulmonary histoplasmosis and nine with progressive disseminated histoplasmosis) were falsely negative by ASR-EIA. All 10 specimens from patients with severe symptoms of progressive disseminated histoplasmosis were positive by ASR-EIA, although the average reading value of these 10 specimens was not significantly different from that of others with positive results. Compared to the MiraVista antigen assay, both the IVD kit and the ASR-EIA were significantly less sensitive in detecting Histoplasma antigen in the urine of patients with histoplasmosis. The ASR-EIA and MiraVista assay had comparable specificity. In conclusion, the ASR-EIA has improved performance compared with the IVD kit in the detection of Histoplasma antigen in the urine. However, users should be aware of the potential for false negative results using the currently recommended cutoff value.

    Histoplasma capsulatum var capsulatum is a dimorphic fungus endemic to the Ohio and Mississippi River Valleys of the United States. In this case report, a 33-year-old woman who presented with a right orbital mass causing progressive vision loss, diplopia, and facial swelling is described. Lateral orbitotomy with lateral orbital wall bone flap was performed for excisional biopsy of the lesion. The 1.5 × 1.8 × 2.3 cm cicatricial mass demonstrated a granulomatous lesion with necrosis and positive staining consistent with Histoplasma capsulatum var capsulatum infection. To the authors' knowledge, this is the first case of orbital histoplasmosis to be reported in the United States and the first case worldwide of orbital histoplasmosis due to Histoplasma capsulatum var capsulatum.

    Amongst the main opportunistic diseases that affect the HIV-positive patient, histoplasmosis is found. This systemic mycosis caused by the fungus Histoplasma capsulatum has the capacity to disseminate from the lung to the skin and oral mucosa. Oral lesions of histoplasmosis can be found with ulcerated or nodular aspect, being always very painful and infiltrating the mucosa. When they are present in the mouth, they strongly indicate the presence of some kind of immunosuppression. This study shows the disease's evolution in an HIV-positive patient, who presented several ulcerated lesions in the oral cavity and facial skin. The symptomatology and clinical aspects of the lesions were not specific for the disease, and due to this, the diagnosis was obtained by cytological smear and oral biopsy. The results of the exams defined the disseminated picture of the infection. The treatment plan involved the use of amphotericin B for the lesions' remission, and, following this, itraconazole was administered in the maintenance phase.

    The diagnosis of histoplasmosis due to Histoplasma capsulatum var capsulatum is based on a direct examination identifying encapsulated yeast with narrow-based budding. Galactomannan antigenemia facilitates diagnosis, as well as the monitoring of patients receiving treatment. The case of a HIV-positive patient from Congo-Brazzaville with a disseminated form of African histoplasmosis highlighted the positive galactomannan antigen in this disease due to Histoplasma capsulatum var duboisii. Galactomannan antigenemia remained high with a very slow decrease during antifungal therapy and slow regression of clinical lesions. African histoplasmosis is a rare disease that is difficult to diagnose and rarely described in immunocompromised patients, in whom differential diagnosis can be common. This observation underlines the importance of the galactomannan antigen assay in patients who have travelled to endemic areas. As in the case of Histoplasma capsulatum var capsulatum, the positivity of the Aspergillus galactomannan antigen is very useful in the diagnosis and monitoring of African histoplasmosis.

    Full Text Available Meningitis is a common evolution in progressive disseminated histoplasmosis in children, and is asymptomatic in many cases. In leukemia, the impaired of the T cells function can predispose to the disseminated form. The attributed mortality rate in this case is 20%-40% and the relapse rate is as high as 50%; therefore, prolonged treatment may be emphasized. We have described a child with acute myeloid leukemia (AML, that developed skin lesions and asymptomatic chronic meningitis, with a good evolution after prolonged treatment with amphotericin B deoxycholate followed by fluconazole.

    asymptomatic. The symptoms of acute or epidemic histoplasmosis are high fever, cough, asthenia and retrosternal pain, as well as enlargement of the cervical lymph nodes, liver and spleen. The most common radiological findings are diffuse reticulonodular infiltrates in both lungs, as well as hilar and mediastinal lymph node enlargement. In chronic pulmonary histoplasmosis, the clinical and radiological manifestations are identical to those of reinfection with pulmonary tuberculosis. Histoplasmosis is diagnosed by means of the identification or culture growth of the fungus in sputum or fiberoptic bronchoscopy specimens. Histopathological examination reveals the fungus itself within or surrounding macrophages, as well as granulomatous lesions with or without caseous necrosis. Double agar gel immunodiffusion is the most easily used and readily available serologic test for making the immunological diagnosis. Acute histoplasmosis with prolonged symptoms requires treatment, as do the disseminated or chronic pulmonary forms of the disease. The drug of choice is itraconazole.

    Full Text Available Histoplasma capsulatum is the most common endemic mycosis worldwide. Although most of the globe's largest urban hubs fall outside this organism's regions of endemicity, clinicians practicing in a metropolis like New York City or Los Angeles must nevertheless remain vigilant for histoplasmosis because of the large immigrant population that is served by its hospitals. H. capsulatum infection ranges from asymptomatic pulmonary infection to life-threatening diffuse pneumonia with dissemination. The early years of the AIDS epidemic first introduced U.S. clinicians working in areas previously unfamiliar with histoplasmosis to newly immunocompromised patients from endemic regions presenting with disseminated H. capsulatum originally acquired in their home countries. Improvement in HIV prevention and therapeutics has reduced the frequency of such cases. Herein we report three cases of histoplasmosis encountered in our New York City institution over the last three years to emphasize that awareness of this infection remains mandatory for the frontline urban clinician.

    Full Text Available Histoplasmosis is a world-wide distributed deep mycosis caused by Histoplasma capsulatum which has been endemic in many countries. We present a case involving an immunocompetent man evidencing the necessity of a multidisciplinary approach and rational requisition of exams. The disease has started as a pulmonary disease mimicking tuberculosis, although the exams have been negative. Immunodiffusion test indicate histoplasmosis, not confirmed by culture of sputum. After days the patient was forwarded by a private doctor for evaluation of oral lesions at our Department of Stomatology. An incisional biopsy revealed a nonspecific granulomatous inflammation and the Grocott-Gomori methenamine silver stain identified scarce oval structures that could represent fungal yeast. Sampling oral lesions with swab, it was observed the typical growth of H. capsulatum on culture. This case highlights the importance of doctor′s integration diagnosing histoplasmosis, while a wide spectrum of clinical manifestations should be expected. Oral lesions may be the critical manifestation leading diagnosis.

    We report a case of a 29-year-old man who presented with intermittent haemoptysis for about 18 months. Previously, his symptoms had been diagnosed as musculoskeletal pain and later as pneumonia. CT found a venous infarct in the right lung in addition to extensive lymphadenopathy in the mediastinum and pulmonary hila, with associated calcifications almost completely occluding the superior vena cava and azygos vein. Further questioning revealed that the patient had once worked on an organic farm in Colorado. Subsequent work up was positive for histoplasmosis yeast antibodies. The patient was diagnosed with fibrosing mediastinitis (FM) and started on itraconazole for 3 months. We note that FM is a rare complication of histoplasmosis and can present as chronic haemoptysis. Travel history is an important aspect of the clinical evaluation. Antifungal agents have shown some efficacy in treating histoplasmosis-related FM.

    Full Text Available A histoplasmose com acometimento único de laringe é uma ocorrência rara da doença, com menos de 100 casos relatados na literatura, quando comparada ao número de pacientes diagnosticados com histoplasmose. Tal localização, quando isolada, pode induzir, erroneamente, ao diagnóstico e tratamento de tuberculose ou câncer de laringe, com casos relatados de tratamentos iniciados para essas doenças. Em um paciente com histoplasmose que desenvolva rouquidão, deve-se pensar no acometimento laríngeo da histoplasmose, enquanto que uma massa laríngea produzindo rouquidão deve incluir em seu diagnóstico diferencial a histoplasmose laríngea. Quando se pensa em histoplasmose como causa de uma lesão laríngea, a biópsia deve ser limitada, removendo a menor quantidade de tecido necessária para o diagnóstico O patologista deve ser avisado da possibilidade do diagnóstico, já que podem ser necessários corantes especiais para o diagnóstico.The incidence of laryngeal histoplasmosis is low when compared to the total number of cases. Less than 100 cases of laryngeal histoplasmosis have been described in the medical literature. Isolated laryngeal involvement may lead to the misdiagnosis and mistreatment of tuberculosis or laryngeal cancer, according to some reports. The development of hoarseness in a patient with histoplasmosis or a laryngeal mass leading to hoarseness, might be suggestive of laryngeal histoplasmosis. When histoplasmosis is included among the differential diagnoses of a laryngeal lesion, the biopsy should be limited to a small tissue fragment, enough to perform histological tests. The laboratory technicians must be warned about the possibility of histoplasmosis, because special dyes have to be used to confirm this diagnosis.

  17. Histoplasmosis in a state where it is not known to be endemic--Montana, 2012-2013.

    Science.gov (United States)

    2013-10-25

    Histoplasmosis is caused by infection with the dimorphic fungus, Histoplasma capsulatum, following inhalation of contaminated soil. Among symptomatic patients, the most common clinical presentation is acute pneumonia. Persons with compromised immune systems are at risk for disseminated histoplasmosis, a severe illness requiring antifungal therapy that is often characterized by fever, malaise, anorexia, and weight loss. H. capsulatum is endemic in the Ohio River and Mississippi River valleys, where it is found in soil enriched with bird droppings and bat guano. During November 2012-February 2013, histoplasmosis was diagnosed in four Montana residents by four different physicians. No epidemiologic links among the cases were identified. Each patient's medical records were reviewed, and their exposure and travel histories were obtained. Three patients reported no recent travel outside of Montana and likely were exposed in Montana, which is west of areas where H. capsulatum is recognized as endemic. One patient reported recent travel to California, where she was exposed to potting soil containing bat guano. Low clinical suspicion, probably related to lack of history of exposure to areas where H. capsulatum is known to be endemic, likely delayed diagnosis and appropriate therapy for three patients. Health-care providers should be aware of the possibility of histoplasmosis in Montana and consider the diagnosis in patients with clinically compatible illnesses.

    Histoplasmosis is endemic to the Midwestern United States, but cases have been reported nearly worldwide. A 1970 study found 3.8% skin test sensitivity to Histoplasma capsulatum in Uganda but no systemic study of histoplasmosis exposure has occurred since the onset of the human immunodeficiency virus (HIV) pandemic. This study investigated the seroprevalence of H. capsulatum and sought previously undetected cases of histoplasmosis in Kampala, Uganda. Serum, cerebrospinal fluid (CSF) and/or urine specimens were obtained from HIV-infected persons with suspected meningitis. Specimens were tested for H. capsulatum IgG and IgM by enzyme immune assay and Histoplasma antigen. 147 of the 257 subjects who were enrolled had cryptococcal meningitis. Overall, 1.3% (2/151) of subjects were serum Histoplasma IgG positive, and zero of 151 were IgM positive. Antigen was not detected in any serum (n = 57), urine (n = 37, or CSF (n = 63) samples. Both subjects with serum Histoplasma IgG positivity had cryptococcal meningitis. Histoplasma capsulatum IgG was detected at low levels in persons with HIV/AIDS in Kampala, Uganda. Histoplasmosis is not widespread in Uganda but microfoci do exist. There appears to be no cross-reactivity between Cryptococcus neoformans and Histoplasma antigen testing, and cryptococcosis appears to be at most, a rare cause of positive Histoplasma IgG.

    A 2-year-old intact female miniature Pinscher weighing 1.7 kg with a body condition score of 2/5 was presented for acute vomiting, lethargy for 2 days, and large petechial skin lesions on the hip region including the tail. Acute pancreatitis was diagnosed by clinical signs, strong positive cPLI test, laboratory test and ultrasound appearance. While the clinical signs associated with acute pancreatitis had improved in 3-5 days, lesion of petechial appeared on the left hip region 7 days after the presentation, with a fast progression into a necrotic tissue along the left side hip. Allogenic platelet rich plasma (PRP) with Weibrich and Kleis method was administered to promote skin healing and regeneration. Gradual and complete improvement in the dog's wound lesions was noted approximately 1 month after applying allogeneic topical PRP. In this case report, allogeneic PRP was applied to a large regional cutaneous defect caused by coagulopathy induced by acute pancreatitis. Topical application of PRP in this case was unique in that allogeneic PRP was used instead of autologous PRP for the first time in cutaneous soft-tissue wound management in the veterinary medical field.

    Lymphocytes from individuals with inactive macular disciform lesions of presumed ocular histoplasmosis challenged with three histoplasmin antigens incorporated tritiated thymidine at a significantly higher rate than histoplasmin-stimulated lymphocytes of matched control and peripheral scar groups. This finding is consistent with the etiologic association of the disciform ocular syndrome and previous systemic infection with Histoplasma capsulatum. The disciform group had a higher mean response than the other two groups to pokeweed mitogen but not to phytohemagglutinin and had higher mean counts per minute to the specific antigens Toxoplasma gondii, Blastomyces dermatitidis, Cryptococcus neoformans, Mycobacterium tuberculosis, M battery, and M gaus, but not to Candida albicans. These data would suggest that individuals with the disciform lesion of presumed ocular histoplasmosis have a hyperreactive cellular immune response; this response may play an important role in the development of the disciform.

    Histoplasmosis is caused by a dimorphic fungus Histoplasma capsulatum in endemic areas, mainly America, Africa, and Asia. In India, it is being reported from most states; however, it is endemic along the Ganges belt. We report a case of an apparently immunocompetent male who presented with 3-month history of fever, cough, and weight loss with recent onset odynophagia and had hepatosplenomegaly and mucocutaneous lesions over the face. The differential diagnosis of leishmaniasis, tuberculosis, leprosy, fungal infection, lymphoproliferative malignancy, and other granulomatous disorders was considered, but he succumbed to his illness. Antemortem skin biopsy and bone marrow aspiration along with postmortem liver, lung, and spleen biopsy showed disseminated histoplasmosis. This case highlights the need for an early suspicion of progressive disseminated histoplasmosis in the presence of classical mucocutaneous lesions even in an immunocompetent patient suffering from a febrile illness. Cure rate approaches almost 100% with early treatment, whereas it is universally fatal if left untreated. PMID:27752372

    2013-01-01

    Mucormycosis is an invasive fungal infection caused by fungi of the order Mucorales, mainly affecting immunocompromised patients. Cutaneous mucormycosis is the third most common clinical form of the disease, after pulmonary and rhino-cerebral. The usual factors predisposing to this infection are hematological malignancies and diabetes mellitus, but a significant proportion of patients are immunocompetent. The agents of mucormycosis are ubiquitous in nature and are transmitted to the skin by direct inoculation, as a result of various types of trauma. These include needle sticks, stings and bites by animals, motor vehicle accidents, natural disasters, and burn injuries. The typical presentation of mucormycosis is the necrotic eschar, but it can present with various other signs. The infection can be locally invasive and penetrate into the adjacent fat, muscle, fascia, and bone, or become disseminated. Diagnosis is difficult because of the nonspecific findings of mucormycosis. Biopsy and culture should be performed. The treatment of mucormycosis is multimodal and consists of surgical debridement, use of antifungal drugs (amphotericin B and posaconazole), and reversal of underlying risk factors, when possible. Mortality rates, although lower than in other forms of the disease, are significant, ranging from 4% to 10% when the infection is localized.

    A histoplasmosis outbreak affecting 6 previously healthy Air Force cadets is herein presented. The patients suffered from fever and respiratory symptoms after having cleaned an abandoned hangar soiled with pigeons and bat droppings. They all presented fever, myalgia, tachypnea, and nonproductive cough. Chest X-ray and CT scan studies showed disseminated reticulonodular images affecting both lungs. Hiliar adenomegalies were also observed. All patients achieved a favourable outcome without antifungal treatment. Both serologic tests searching for specificic antibodies (immunodiffusion and counterimmunoelectrophoresis) and histoplasmin skin tests were positive in all cases. Five soil samples mixed with pigeons and bat droppings were collected from the hangar. Suspensions of these samples were inoculated into 20 hamsters by intraperitoneal injection; mycelial phase of H. capsulatum was isolated from liver and spleen cultures. The genetic profile of this strain was compared with 12 isolates obtained from Argentinean patients, and a great degree of homogeneity was observed (> 96% similarity). Although histoplasmosis is endemic in the wet Pampas, this is the first epidemic outbreak reported south of the 34th parallel.

    Histoplasmosis has been described as the most common endemic mycosis in the United States. However, histoplasmosis is not nationally notifiable. Its presumed geographic distribution is largely derived from skin test surveys performed during the 1940s, and information about its local features comes primarily from outbreak investigations. We conducted a literature review to assess epidemiologic features of histoplasmosis outbreaks in the United States. During 1938-2013, a total of 105 outbreaks involving 2,850 cases were reported in 26 states and the territory of Puerto Rico. Common exposure settings were chicken coops and buildings or other structures undergoing renovation or demolition. Birds, bats, or their droppings were reported to be present in 77% of outbreak settings, and workplace exposures were reported in 41% of outbreaks. The continued occurrence of histoplasmosis outbreaks, particularly work-related ones involving known disturbance of bird or bat droppings, highlights the need to increase awareness of the disease.

On November 4, ADH was notified by a pediatric infectious diseases specialist regarding seven potential cases of pulmonary histoplasmosis associated with a family gathering that included a bonfire that burned bamboo from a grove that had been a red-winged blackbird roost. These reports prompted an outbreak investigation to ensure that the persons involved received appropriate medical care, to identify whether any novel exposures were associated with illness, and to determine whether any factors were associated with hospitalization. The investigation found that, among the 19 attendees at the family gathering, seven were confirmed with histoplasmosis, 11 were probable, and one did not have histoplasmosis.

    Histoplasmosis is a fungal infection that, although not endemic in Japan, has seen a rise in the number of Japanese cases since the mid-1980s. Diagnosis of the disease is not straightforward, and the main method of detection, fungal culture (which has biosafety-related issues), is of low sensitivity in general. Alternative methods that depend on antibody or antigen detection have had limited use. We have developed a histoplasmosis detection method based on PCR amplification of the Histoplasma capsulatum M antigen gene. We compared this method with fungal culture and serological diagnostic techniques. Among five cases that were finally diagnosed as histoplasmosis, the fungal culture method was only successful in identifying one such case. Although the presence of anti-H. capsulatum antibodies was confirmed in three cases, our PCR method identified four of five cases of histoplasmosis. The performance of our PCR method could not be compared with the antigen detection method, which is used in the United States but is not routinely used in Japan. However, the PCR method was shown to have high sensitivity and specificity for H. capsulatum. Although the number of histoplasmosis cases examined in this study was small, our data suggest that the molecular diagnosis technique has potential for increasing the reliability of histoplasmosis diagnosis when used in combination with established methods.

    Full Text Available Abstract Background Patients with rheumatic diseases including rheumatoid arthritis (RA are at increased risk for infections related to both the disease and its treatments. These include uncommonly reported infections due to histoplasmosis. Methods Medical record review of all patients with a diagnosis of RA who developed new histoplasmosis infection in an endemic region between Jan 1, 1998 and Jan 30, 2009 and who were seen at Mayo Clinic in Rochester, Minnesota was performed. Results Histoplasmosis was diagnosed in 26 patients. Most patients were on combination therapies; 15 were on anti-tumor necrosis factor (anti-TNF agents, 15 on corticosteroids and 16 on methotrexate. Most received more than 6 months of itraconazole and/or amphotericin treatment. Two patients died of causes unrelated to histoplasmosis. Anti-TNF treatment was restarted in 4/15 patients, with recurrence of histoplasmosis in one. Conclusions In this largest single center series of patients with RA and histoplasmosis in the era of immunomodulatory therapy, we found that most patients had longstanding disease and were on multiple immunomodulatory agents. Most cases were pulmonary; typical signs and symptoms of disease were frequently lacking.

La fuente de infección es la tierra rica en desechos orgánicos, y los seres humanos y otros animales se infectan por inhalación de las microconidias en la forma de micelios. La mayoría de las infecciones son asintomáticas o presentan manifestaciones respiratorias leves que curan espontáneamente. Las formas clínicas graves se producen por inhalación masiva de esporas en la infección primaria o por fallas en los mecanismos locales o generales de la inmunidad. La histoplasmosis es una infección fúngica de distribución geográfica amplia, que afecta a más de 60 países; sin embargo, su incidencia es más alta en América. Las áreas endémicas son las zonas de clima templado, subtropical o tropical húmedo, próximas a cursos de agua dulce. Los suelos suelen contener deyecciones de pájaros negros, como los estorninos, de aves de corral y de murciélagos. Estos lugares facilitan el desarrollo masivo de micelios de H. capsulatum y dan origen a los llamados "focos epidémicos". En ellos se producen infecciones masivas y brotes cuando varias personas o animales se exponen simultáneamente a esta fuente de infección. Estos brotes se producen por el ingreso a grutas, la limpieza de gallineros, la utilización de heces de aves como fertilizantes o por la remoción de tierra durante la ejecución de obras públicas, en lugares contaminados, etc. Las áreas donde se ha registrado el mayor número de casos clínicos se sitúan a lo largo de los valles de los ríos Ohio, Mississippi y Missouri en Norteamérica, en diversas zonas de México y del istmo centroamericano y en las cuencas de los ríos Orinoco, Magdalena, Amazonas, San

    An infant with cutaneous amebiasis of the vulva and amebic liver abscess is described. Epidemiologic investigations and serologic studies were crucial in establishing the diagnosis. The vulvar amebic ulcers responded dramatically to metronidazole therapy. Cutaneous amebiasis is a rare complication of Entamoeba histolytica infection which should be considered in the differential diagnosis of perineovulvar or penile ulcers. Cutaneous amebiasis may also occur on the abdominal wall surrounding a draining hepatic abscess, colostomy site, or laparotomy incision.

    Abstract. Coinfection with tuberculosis in some countries occurs in 8-15% of human immunodeficiency virus (HIV) -infected patients who have histoplasmosis. This coinfection interferes with prompt diagnosis, and treatment is difficult because of drug interactions. We retrospectively reviewed the cases of 14 HIV-infected patients who had concomitant tuberculosis and histoplasmosis. The most frequent clinical manifestations were weight loss (85.7%), asthenia (78.5%), and fever (64.2%). The diagnosis of histoplasmosis was made primarily by histopathology (71.4%), and the diagnosis of tuberculosis was made by means of direct microscopic examination (71.4%). Death occurred in two patients, and relapse of both infections occurred in one patient. Moxifloxacin was substituted for rifampicin in six patients, with good outcomes noted for both infections. The clinical presentation does not readily identify acquired immunodeficiency syndrome (AIDS) patients who have tuberculosis and histoplasmosis. The use of a fluoroquinolone as an alternative agent in place of rifampicin for tuberculosis allows effective therapy with itraconazole for histoplasmosis.

    1981-11-15

    The case histories of two young children who experienced skin rashes involving various areas of the body are reported. The diagnosis of pure cutaneous histiocytosis-X was established after extensive studies revealed no other organ involvement. The patients were treated with oral corticosteroids. Currently, both children are in good health, show no evidence of disease, and have been followed over a four-to-five-year period. Therapy with corticosteroids may not be indicated with pure cutaneous histiocytosis-X unless there is evidence of extracutaneous dissemination or rapid progression of the disease.

    In the second part of this review on the deep mycoses, we describe the main systemic mycoses-paracoccidioidomycosis, coccidioidomycosis, histoplasmosis, mucormycosis, and cryptococcosis-and their cutaneous manifestations. Skin lesions are only occasionally seen in deep systemic mycoses either directly, when the skin is the route of entry for the fungus, or indirectly, when the infection has spread from a deeper focus. These cutaneous signs are often the only clue to the presence of a potentially fatal infection. As with the subcutaneous mycoses, early diagnosis and treatment is important, but in this case, even more so.

    Full Text Available Se describe un brote de histoplasmosis que afectó a 6 cadetes de la Fuerza Aérea Argentina, sin antecedentes patológicos previos. Todos consultaron por problemas respiratorios después de haber limpiado un hangar. En ese recinto se encontraron abundantes deyecciones de animales, presuntamente de palomas y murciélagos. Los pacientes sufrieron fiebre, mialgias, taquipnea y tos no productiva. Las radiografías y tomografías de tórax mostraron imágenes pulmonares micronodulares, engrosamiento de los tabiques interalveolares y adenopatías hiliares. Todos tuvieron una evolución favorable y no requirieron tratamiento antifúngico. Las pruebas de inmunodifusión y contrainmunoelectroforesis con antígenos de Histoplasma capsulatum fueron positivas, al igual que las intradermorreacciones con histoplasmina. Se recogieron 5 muestras de tierra del lugar, las que fueron inoculadas por vía intraperitoneal a 20 hámsteres. De los cultivos de hígado y bazo de dichos animales se consiguió aislar la fase micelial de H. capsulatum. La cepa aislada se comparó con las obtenidas de 12 pacientes argentinos utilizando perfiles genéticos y se observó un clado único con más de 96% de similitud, lo que confirma la homogeneidad de las cepas argentinas. Si bien la histoplasmosis es endémica en la Pampa húmeda, este es el primer brote totalmente documentado al sur del paralelo 34°.An histoplasmosis outbreak affecting 6 previously healthy Air Force cadets is herein presented. The patients suffered from fever and respiratory symptoms after having cleaned an abandoned hangar soiled with pigeons and bat droppings. They all presented fever, myalgia, tachypnea, and nonproductive cough. Chest X-ray and CT scan studies showed disseminated reticulonodular images affecting both lungs. Hiliar adenomegalies were also observed. All patients achieved a favourable outcome without antifungal treatment. Both serologic tests searching for specificic antibodies

    Full Text Available Malaria is an infectious disease caused by protozoa of the genus Plasmodium. Cutaneous lesions in malaria are rarely reported and include urticaria, angioedema, petechiae, purpura, and disseminated intravascular coagulation (DIC. Here, five malaria cases associated with cutaneous lesions have been described. Out of the five cases of malaria, two were associated with urticaria and angioedema, one case was associated with urticaria, and other two were associated with reticulated blotchy erythema with petechiae. Most of the cutaneous lesions in malaria were nonspecific and reflected the different immunopathological mechanism in malarial infection.

    Adrenal histoplasmosis is one of the most common adrenal granulomatous infections in endemic areas. Although CT or MRI findings of adrenal histoplasmosis have been documented, there are no reports regarding {sup 18}F-fluorodeoxyglocose (FDG) positron emission tomography (PET) findings. We report a case of bilateral adrenal histoplasmosis showing a significantly high uptake of {sup 18}F-fluorodeoxyglocose on PET study. Adrenal histoplasmosis should be considered as one of the differential diagnoses in cases of adrenal tumors with intense FDG uptake, even in non-endemic areas. (orig.)

    Cutaneous zygomycosis is a fungal infection caused by zygomycetes that affects the skin. It occurs in uncontrolled diabetic patients and immunosuppressed individuals. It has 2 clinical forms: primary cutaneous zygomycosis and secondary cutaneous zygomycosis. The first is characterized by necrotic lesions and the fungus is usually inoculated by trauma. If diagnosed early, it generally has a good prognosis. Secondary zygomycosis is usually a complication and extension of the rhinocerebral variety that starts as a palpebral fistula and progresses to a necrotic lesion with a poor prognosis. The diagnosis is made by identification of the fungus by direct KOH examination, culture, and biopsy. Treatment for the primary disease is surgical debridement plus amphotericin B. The secondary type is treated with amphotericin B and/or posaconazole.

    Sarcoidosis is a multi-organ granulomatous disorder of unknown cause. Skin sarcoidosis occurs in about 25% of patients with systemic disease and may also arise in isolation. A wide range of clinical presentations of cutaneous sarcoidosis is recognised. The diagnosis rests on the presence of non-caseating granulomas on skin biopsy and the exclusion of other granulomatous skin disease. The treatment and overall prognosis of cutaneous sarcoidosis is primarily dependent on the degree of systemic involvement. In patients with aggressive disease limited to the skin immunosuppressive therapy may be indicated.

    Cutaneous Leishmaniasis (CL) is a vector borne disease caused by various species of the Leishmania parasite. CL is endemic in the province of Balochistan in Pakistan. In certain instances a Human Immunodeficiency Virus (HIV)-related immunocompromised is associated with atypical clinical presentation and occurrence of reactivated lesions of CL. Such presentations respond poorly to the standard treatment and frequent relapses are noted. We are reporting three cases of localized and disseminated CL due to Leishmania tropica which responded to meglumine antimoniate. Due to the fact that CL is endemic in Balochistan, we did not consider HIV infection as a causative organism. It was their presentation with history of weight loss and fever that prompted Enzyme-linked Immunosorbent Assay (ELISA) tests for HIV, which turned out to be positive. CL is becoming visible as an opportunistic infection associated with HIV/AIDS and may even be the first symptom in HIV positive patients in an endemic area.

Polish patients with CLM are usually tourists visiting tropical and subtropical countries. The first symptoms do not always appear as creeping eruptions, which complicates the diagnosis. Objective. To present the case of a man with CLM after returning from Thailand to Poland and associated diagnostic difficulties. Case report. We present a case of a 28-year-old man who returned to Poland from Thailand. The first symptoms appeared as disseminated pruritic papules. No improvement after treatment with corticosteroids and antihistamines was observed. The diagnosis was established after the appearance of serpentine erythemas and improvement after albendazole therapy. Conclusions. In the case of returnees from exotic countries suffering from raised, pruritic rashes, and no improvement after treatment with corticosteroids and antihistamines, parasitic etiology should be considered.

    Histoplasmosis is a zoonotic systemic mycosis caused by Histoplasma capsulatum. We report a case of a female canine, 4 years old, presenting multifocal lymphadenitis and skin and gingival lesions, in Ecuador. Based on cytological, histopathological, histochemical analyses, fungal culture and DNA sequencing of the ITS region of the fungus, the diagnosis confirmed the presence of H. capsulatum as the agent of infection. The treatment plan included ketoconazole with a satisfactory outcome.

    Full Text Available Case summary Based on demonstration of the yeast phase of Histoplasma capsulatum on fine-needle aspirate cytology of the kidney, a 5-year-old cat was diagnosed with histoplasmosis. Urine and serum were tested for antigen via a Histoplasma antigen enzyme immunoassay. At the time of diagnosis, and on multiple occasions during antifungal treatment, antigenemia was detected without antigenuria. The cat was treated with standard therapy and achieved clinical remission. Relevance and novel information Diagnosis is most commonly made by finding the yeast phase of H capsulatum via cytology of fluid samples or cytology or histopathology of infected tissues. In certain cases this may require invasive tests. Recently, a non-invasive test, a Histoplasma antigen enzyme immunoassay, has been shown to be a sensitive test for supporting the diagnosis of histoplasmosis in cats. Urine has been considered the biologic specimen of choice for antigen testing and there is a paucity of information concerning the use of other specimens such as serum. The case herein reports a cat with antigenemia without antigenuria. These findings suggest that further research is necessary to better understand the ideal biologic sample or combination of samples as it pertains to antigen testing in cats. It also suggests that to maximize sensitivity both urine and serum may need to be tested in cats with suspected histoplasmosis.

    2002-03-01

    Cutaneous leiomyosarcoma is a rare soft-tissue sarcoma with negligible metastatic potential, but local recurrence rates after surgical excision have ranged from 14 percent to 42 percent. Unlike other sarcomas, guidelines for the optimal surgical excision margin of cutaneous leiomyosarcoma are not clearly defined in the existing literature. A review of local experience with this condition revealed eight patients over 12 years, none of whom developed local recurrence or distant metastases. This is despite poor prognostic factors in seven patients and excision margins ranging from 1 to 27 mm. These findings are compared with previously published data, and conclusions are drawn based on analysis of the collective results. Complete surgical excision with a narrow margin is recommended, and patients should be observed for a minimum of 5 years after surgery.

    Pulmonary histoplasmosis is a granulomatous disease, whose diagnosis is not always easy, as it may simulate metastatic lesions due to similar radiographic findings. We herein report two cases of histoplasmosis with solitary pulmonary nodule in asymptomatic patients with histories of cancer surgeries, whose diagnoses were confirmed by postoperative pathological examinations. Doctors must pay attention to risk factors for immunosuppression such as the histories of chemotherapy, radiotherapy, or malignancy, which may increase chances of developing histoplasmosis. Limited surgical intervention is the treatment of choice for these localized lesions.

Hasta el año 2008 se habían analizado 434 encuestas de pacientes provenientes de 20 departamentos, la mayoría de Antioquia, seguido del Valle y Cundinamarca. Por lo tanto, estos resultados no están indicando que la histoplasmosis sea más frecuentemente diagnosticada en estos departamentos como lo expresan los autores, tal vez fueron los que más informaron ya que es un reporte voluntario. La histoplasmosis es causada por el hongo dimórfico Histoplasma capsulatum que presenta dos variedades patógenas para el ser humano, H. capsulatum var. capsulatum e H. capsulatum var. duboisii2, el cual no se adquiere por la inhalación de micelios como es manifestado en el artículo, las estructuras infectantes corresponden a fragmentos de hifas y principalmente las microconidias (2-4 mm que llegan a los bronquiolos y alveolos pulmonares3. Es importante aclarar que el concepto de micelio corresponde a masa de hifas, por lo tanto, no es correcto sugerir que esta estructura es la responsable de la infección. Posteriormente, las microconidias se transforman en levaduras y debido a la alta actividad fagocitaria de los macrófagos alveolares son fagocitadas y dentro de ellos se multiplican, llevando a veces a la destrucción del fagocito y a la infección de nuevas células4. Luego, el macrófago cargado con el microorganismo es responsable de la diseminación de las blastoconidias a órganos ricos en fagocitos mononucleares.

    2003-06-01

    Leishmaniasis is a vector-borne disease caused by an obligate intracellular protozoa, Leishmania, which resides in macrophages. The parasite is transmitted by an infected female sandfly. The incidence of cutaneous leishmaniasis approaches 2 million new cases per year with 90% of the cases occurring in the "Old World", while the "New World" accounts for the rest. Infection may be restricted to the skin with development of characteristic ulcers, or may affect the mucous membranes in its mucocutaneous form. The clinical diagnosis is verified by the presence of amastigotes in slit-skin smears. Therapeutic modalities include systemic treatments such as the pentavalent antimony compound sodium stibogluconate, liposomal formulations of amphotericin B, oral ketoconazole or itraconazole, as well as topical paromomycin sulphate, local heat, freezing with liquid nitrogen, or photodynamic therapy. An effective vaccine is not available.

    Cutaneous mucormycosis is an emerging fungal infection caused by opportunistic fungi of the phylum Glomeromycota. It is frequent in poorly controlled diabetic patients and individuals with immunosuppression. It is usually acquired by direct inoculation through trauma. The clinical presentation is nonspecific, but an indurated plaque that rapidly evolves to necrosis is a common finding. Diagnosis should be confirmed by demonstration of the etiological agent and new molecular diagnostic tools have recently been described. It is an invasive life-threatening disease and in order to improve survival, a prompt diagnosis and multidisciplinary management should be provided. The treatment of choice is amphotericin B, but new azoles, such as posaconazole and isavuconazole, must be considered.

    Full Text Available Abstract Background Pulmonary histoplasmosis is a mycotic infection that often resembles pulmonary malignancy and continues to complicate the evaluation of pulmonary nodules. Case presentation We report a case of an immunocompetent patient who, despite adequate treatment for known histoplasmosis lung infection, presented with radiological and F-18 fluorodeoxyglucose (FDG positron emission tomography (PET findings mimicking primary lung malignancy which eventually required surgical resection. Conclusion Histoplasmosis infection may radiologically resemble pulmonary malignancy, often causing a diagnostic dilemma. PET imaging is currently used for and considered accurate in the evaluation of pulmonary nodules. However, overlap in PET standardized uptake value (SUV between granulomatous and malignant lesions decreases the accuracy of PET as a diagnostic modality. Future advances in PET imaging are needed to improve its accuracy in the evaluation of pulmonary nodules in areas where histoplasmosis is endemic.

    Korea is not known as an endemic area for Histoplasma. However, we experienced a case of histoplasmosis in a person who had never been abroad. A 65-year-old female was admitted to the hospital for evaluation of multiple lung nodules. A computed tomography (CT) scan of the chest showed multiple ill-defined consolidations and cavitations in all lobes of both lungs. The patient underwent a CT-guided lung biopsy, and a histopathology study showed findings compatible with histoplasmosis. Based on biopsy results and clinical findings, the patient was diagnosed with chronic cavitary pulmonary histoplasmosis. The patient recovered completely following itraconazole treatment. This is the first case report of pulmonary histoplasmosis unconnected with either HIV infection or endemicity in Korea.

    A case is presented of isolated renal histoplasmosis in a Nagasaki woman who died of pulmonary tuberculosis following massive x-ray therapy for squamous carcinoma of the mouth. No primary pulmonary lesion was identified. While the patient's history includes a 40-year residence in Malaysia and a brief internment in New Delhi where a few cases of histoplasmosis have been reported, she had been in Japan for 16 years prior to her death. In view of the presently-known absence of viability of Histoplasma in old primary foci, it was concluded that the infection was acquired in Japan and represents the first case of Histoplasma capsulatum infection reported from Japan (37 references, 5 figures). A second case is presented of a 15-year-old Japanese girl with a clinical history and postmortem findings of a subacute necrotizing encephalomyelopathy is reported. The patient's parents were consanguinous and a similar disease was also present in one sibling. This case and those available in the literature indicate that a severe peripheral neuropathy associated frequently with secondary degeneration of the dorsal white columns of the spinal cord constitutes an integral part of the disorder. The presence of peripheral neuropathy reminiscent of that due to deficiency of thiamine and pantothenic acid, frequent familial occurrence of the disorder and consanguinity in some of the parents give support to the speculation of previous investigators that the disease may represent an inborn error of metabolism especially of pyruvate metabolism. 11 references, 15 figures, 1 table.

La forma meníngea, considerada como una de las manifestaciones más graves de esta micosis, suele presentarse en individuos con alteraciones en la inmunidad celular: pacientes con síndrome de inmunodeficiencia humana adquirida, con lupus eritematoso sistémico o con trasplante de órgano sólido, así como en lactantes, debido a su inmadurez inmunológica. La forma de presentación más usual es de resolución espontánea y se observa en individuos inmunocompetentes que se han expuesto a altas concentraciones de conidias y fragmentos miceliares del hongo. En estas personas, la afección se manifiesta por trastornos pulmonares y por la posterior diseminación a otros órganos y sistemas. Se presenta un caso de histoplasmosis del sistema nervioso central en un niño inmunocompetente.

    In the present study, the case of a 54-year-old male patient diagnosed with pulmonary histoplasmosis is reported, with the aim to increase the understanding of the disease characteristics and thereby facilitate the diagnosis and treatment of pulmonary histoplasmosis. Clinical manifestations, diagnosis, treatment and clinical outcomes of the present case of pulmonary histoplasmosis were described. In addition, 76 histoplasmosis patients with complete clinical data were reviewed by searching the literature for relevant studies published during 1990 and 2015. The disease was mainly manifested as cough in the present case, while imaging examination detected a lump shadow in the right lung, accompanied by exudative lesions. Initially, the patient was suspected to have bacterial pneumonia, but subsequently the diagnosis of pulmonary histoplasmosis was confirmed by lung biopsy. The symptoms were alleviated following itraconazole treatment. The patient was physically stable and had no recurrence during the subsequent follow-up period. In conclusion, pulmonary histoplasmosis is characterized by non-specific clinical and imaging manifestations, and lung tissue biopsy or respiratory pathogen culture are regarded as the diagnostic gold standards. Individualized antifungal medication should be administered based upon the patients' situation in terms of dosage and duration. PMID:27882146

    A 33-year-old man presented with an ulcerated nodule on his left eyelid and eyebrow that was unresponsive to broad-spectrum antibiotics. Incisional biopsies were performed, and cultures were positive for Coccidioides immitis. An extensive work-up revealed no systemic involve ment of disseminated coccidioidomycosis. The patient was treated with oral itraconazole for 6 months with resolution of the lesion. Few cases of primary cutaneous coccidioidomycosis have been reported. The authors describe a primary cutaneous coccidioidomycosis lesion of the eyelid without disseminated disease.

    Cutaneous lymphomas are uncommon in people and companion animals. The tumors can be broadly categorized into epitheliotropic and nonepitheliotropic forms, which appear to have different biological behaviors. The present case describes a feline cutaneous epitheliotropic lymphoma. Masses in a 9-year-old cat were first identified on the tail. The cat was treated with chemotherapy, but additional skin masses developed on the flank, face, and ears. Local radiation induced transient tumor regression, but eventual dissemination prompted euthanasia 13 months after initial tumor appearance. Granular lymphocytes were consistently detected on blood smears, and histologically, the tumor involved the skin and superficial subcutis. Tumor lymphocytes expressed cluster of differentiation 3 (CD3) and perforin molecules, suggestive of a cytotoxic phenotype. Location, histopathological features, and perforin expression were similar to a distinct entity in human medicine designated primary cutaneous, CD8-positive, epidermotropic, cytotoxic, T-cell lymphoma.

    2016-01-01

    Metastatic ovarian cancer uncommonly presents with skin metastasis. When present, skin metastases of ovarian cancer are usually localized in the vicinity of the primary tumor. We report a case of a 58-year-old woman with a rapid growing erythematous, well-defined nodule localized on the left nasal ala. A skin biopsy was performed and histopathological and immunohistochemical findings were compatible with a cutaneous metastasis of adenocarcinoma. A systematic investigation revealed a bilateral ovarian cystadenocarcinoma associated with visceral dissemination, likely associated with nose cutaneous metastasis. We report a very uncommon case because of the presentation of ovarian carcinoma as cutaneous metastasis. To our knowledge, this atypical localization on the nose has not been described yet in the literature.

    Full Text Available Cutaneous metastases of rectal carcinoma is a rare event. It occurs in fewer than 4% of all patients with rectal cancer. When present, it typically signifies a disseminated disease with a poor prognosis. Early detection and proper diagnosis of metastatic rectal cancer can significantly alter treatment and prognosis. We report a 70-year-oldmale who underwent rectal resection with permanent colostomy for rectal adenocarcinoma since seven years. The patient recently developed multiple skin nodules, mainly in his face, scalp, and upper trunk, associated with itching. Fine needle aspiration cytology from a face nodule was done which revealed metastatic adenocarcinoma associated with severe inflammation. Cutaneous metastasis of rectaladenocarcinoma is an unusual event that presents mainly in the form of skin nodules and could be the first sign of metastasis. Early diagnosis of cutaneous metastasis in these patients is important because it can alter treatment and prognosis.

    Histoplasmosis is known to be endemic in various parts of the world, especially in North and Latin America. In Japan, Histoplasma capsulatum has rarely been isolated from the natural environment. To date, only seven cases of histoplasmosis have been reported in Japan including some that were contracted in foreign countries. Herein, we report the occurrence of acute histoplasmosis among Japanese travelers who were exposed to bat guano in a cave near Manaus, Brazil. A group of 8 Japanese travelers entered a cave for a total of 2 hours in March, 1993. All the visitors had been healthy and had no history of abnormal chest roentgenograms. From 10 to 20 days after the exposure, 7 (87.5%) of the 8 individuals developed abnormal symptoms including fever, malaise, loss of appetite, myalgia, arthralgia, chest pain and dry cough. Five (62.5%) had nodular infiltrative shadows with or without hilar lymphadenopathy in the chest roentgenograms. Eight (100%) of the individuals showed serologic evidence of histoplasmosis. Despite the small number of subjects, this high rate of infection may be related to the fact that the subjects stayed in an enclosed area where air exchange was minimal, at the end of a deep cave infested with numerous bats. The cave involved has never been documented as being endemic for histoplasmosis. The threat of H. capsulatum infection in bat-inhabited caves should be emphasized to travelers and also to physicians.

    Histoplasmosis causes a significant mortality, especially persons living with human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) from developing countries where access to both appropriate diagnostic methods and antiretroviral therapy are limited. A total of 81 physicians assigned to 17 Colombian departments (states) received training in the clinical, epidemiological, and diagnostic aspects of histoplasmosis. Once this training was received and during the period of October 2009-November 2012, these physicians sent biological samples for immunodiagnostic, mycological, and molecular tests from their patients with suspicion of histoplasmosis. A total of 1,536 samples from 768 patients were evaluated. Of the 768 patients studied, 463 (60%) were HIV positive, 214 (28%) HIV negative, and in 91 (12%) this diagnosis was unknown, and 538 (70%) were males. The 1,536 specimens studied comprised 722 sera, 439 blood samples, and 241 urines, which were tested by immunodiffusion (ID), culture, and antigenuria, respectively; in addition, 134 specimens were tested by performing a molecular assay. Histoplasmosis was diagnosed in 133 patients (17%). After the training, we observed more diagnoses from 27 to 44 cases per year. In this study, a significantly increased number of histoplasmosis cases reported by year were observed after implementing an educational training program.

    Full Text Available Three unusual clinical forms of sporotrichosis described in this paper will be a primer for the clinicians for an early diagnosis and treatment, especially in its unusual presentations. Case 1, a 52-year-old man, developed sporotrichosis over pre-existing facial nodulo-ulcerative basal cell carcinoma of seven-year duration, due to its contamination perhaps from topical herbal pastes and lymphocutaneous sporotrichosis over right hand/forearm from facial lesion/herbal paste. Case 2, a 25-year-old woman, presented with disseminated systemic-cutaneous, osteoarticular and possibly pleural (effusion sporotrichosis. There was no laboratory evidence of tuberculosis and treatment with anti-tuberculosis drugs (ATT did not benefit. Both these cases were diagnosed by histopathology/culture of S. schenckii from tissue specimens. Case 3, a 20-year-old girl, had multiple intensely pruritic, nodular lesions over/around left knee of two-year duration. She was diagnosed clinically as a case of prurigo nodularis and histologically as cutaneous tuberculosis, albeit, other laboratory investigations and treatment with ATT did not support the diagnosis. All the three patients responded well to saturated solution of potassium iodide (SSKI therapy. A high clinical suspicion is important in early diagnosis and treatment to prevent chronicity and morbidity in these patients. SSKI is fairly safe and effective when itraconazole is not affordable/ available.

    Full Text Available Cutaneous leishmaniasis is a disease caused by intracellular protozoal parasites belonging to the genus Leishmania. Immune suppression caused by HIV infection is an important factor for atypical presentation and widespread progression of cutaneous leishmaniasis. Diffuse (disseminated cutaneous leishmaniasis and HIV co-infection is emerging as an extremely serious new disease. A 38-year-old HIV-positive man presented with a 12-month history of a progressive papule and nodular eruptions on face and extremities with infiltrations of nasal and oral mucosa. We report the case due to its atypical, widespread muco-cutaneous presentation masquerading as lepromatous leprosy.

    Full Text Available Histoplasmosis is an endemic mycosis of the Americas, Africa, and Asia. In Spain, it is the most common imported endemic mycosis appearing in the literature, and its incidence is on the rise. Proper differential diagnosis of the disease must be taken into consideration by otorhinolaryngologists, as the clinical manifestations of histoplasmosis may simulate more prevalent diseases such as cancer or tuberculosis. We present the case of a Spanish patient with focal involvement of the larynx and offer a review of the relevant literature.

    1998-01-01

    Histoplasmosis is a fungal disease caused by the dimorphous fungus Histoplasma capsulatum (Hc). Cyclophosphamide (Cy) was used as an immunomodulator capable of modifying the course of the disease, as well as of regulating the mechanisms involved in T-lymphocyte mediated immune response. Rats were subjected to intracardiac inoculation of Hc followed by a fractionated treatment with a 100 mg/kg body weight dose of Cy on days +4, +5, +6, +7 and +11 pi. Until day 26 pi, treatment with Cy caused 85% mortality whereas no mortality was observed among animals only inoculated with Hc. On day 14 pi, the group of Hc animals showed a delayed hypersensitivity test (DH) of 26.60 + 13.96 as determined by the swelling of the leg. Conversely, DH was significantly depressed in rats inoculated with Hc and treated with Cy: 3.88 +/- 1.00 (p < 0.01). Colony forming units count in this group was 2020 CFU/g of spleen, and 24 CFU/g of spleen (p < 0.01) in controls. A macroscopic study of the organs revealed that the animals in the Hc+Cy group had spleenomegaly and lungs with granuloma and hemorrhagic spots. The controls only presented small lung abscesses. These findings lead to the conclusion that Cy causes a deterioration of cell mediated immune response which results in the manifestation of an acute, fatal experimental mycosis.

    Members of the genus Rhizopus within the class Zygomycetes can cause devastating opportunistic infections. Cutaneous disease arising from direct inoculation of fungal spores has the potential to disseminate widely. Here, we describe a dramatic case of cutaneous Rhizopus infection involving the penis in a patient with acute myelogenous leukemia. Despite aggressive surgical debridement, systemic antifungal therapy, and donor lymphocyte infusion, the infection was ultimately fatal. This case illustrates the unique diagnostic and therapeutic challenges in the clinical management of cutaneous Rhizopus infection.

Because of the role of TNF-α in the host defenses, anti-TNF therapy has been associated with an increase the risks of granulomatous infections. Objective To report the first case of adalimumab-associated invasive histoplasmosis presenting as an acute hepatitis-like syndrome and febrile pneumonitis in a patient with Crohn’s disease. Method Case report of a patient with progressive histoplasmosis confirmed by percutaneous fine needle aspiration biopsy lung and urine Histoplasma antigen. Results We present the case of a young man with CD who developed pneumonia and acute hepatitis-like features caused by Histoplasma capsulatum infection during adalimumab therapy. To the best of our knowledge, this acute hepatitis-like manifestation has never been reported as a presentation of the histoplasmosis in patients with Crohn’s disease. Conclusions This case underscores the potential risk for serious infection that may arise in this setting and should alert clinicians to the need to consider the histoplasmosis diagnosis in patients presenting with acute hepatitis-like syndrome associated with prolonged febrile illness or pneumonitis during therapy with anti-TNF-α antibodies.

    Histoplasmosis is a systemic mycosis caused by Histoplasma capsulatum, a dimorphic fungal pathogen that can infect both humans and animals. This disease has worldwide distribution and affects mainly immunocompromised individuals. In the environment, H. capsulatum grows as mold but undergoes a morphologic transition to the yeast morphotype under special conditions. Molecular techniques are important tools to conduct epidemiologic investigations for fungal detection, identification of infection sources, and determination of different fungal genotypes associated to a particular disease symptom. In this study, we performed a systematic review in the PubMed database to improve the understanding about the molecular epidemiology of histoplasmosis. This search was restricted to English and Spanish articles. We included a combination of specific keywords: molecular typing [OR] genetic diversity [OR] polymorphism [AND] H. capsulatum; molecular epidemiology [AND] histoplasmosis; and molecular epidemiology [AND] Histoplasma. In addition, we used the specific terms: histoplasmosis [AND] outbreaks. Non-English or non-Spanish articles, dead links, and duplicate results were excluded from the review. The results reached show that the main methods used for molecular typing of H. capsulatum were: restriction fragment length polymorphism, random amplified polymorphic DNA, microsatellites polymorphism, sequencing of internal transcribed spacers region, and multilocus sequence typing. Different genetic profiles were identified among H. capsulatum isolates, which can be grouped according to their source, geographical origin, and clinical manifestations.

    Histoplasmosis, caused by Histoplasma capsulatum, is an endemic mycosis in many countries of the world except for Japan. Outbreaks of histoplasmosis among Japanese people are very rare and are mainly imported by travelers. We report an outbreak of histoplasmosis among healthy Japanese people who traveled to a resort area in Southeast Asia. Three young Japanese women traveled to Langkawi island, Malaysia and stayed on the island for five days without visiting caves, a known reservoir of H. capsulatum. All three individuals developed flu-like symptoms with multiple nodule shadows on chest X rays or chest CT scans at around ten days after their return to Japan. Serum samples obtained from the three subjects were positive for anti-Histoplasma antibody and specific PCR for H. capsulatum on lung biopsy specimens and the serum from one patient was positive. The clinical course of all three patients improved without the use of anti-fungal agents and no recurrence has been confirmed. Clinical attendants should consider histoplasmosis when they see patients with flu-like symptoms with abnormal chest X-rays after visiting H. capsulatum endemic areas, especially Southeast Asia.

    Histoplasma capsulatum sporadically causes severe infections in solid organ transplant (SOT) patients in the Midwest, but it has been an unusual infection among those patients followed at the University of Nebraska Medical Center (UNMC), located at the western edge of the 'histo belt.' Nine SOT patients with histoplasmosis are described (6 renal or renal-pancreas and 3 liver recipients) who developed severe histoplasmosis over a recent 2.5-year period at UNMC. Symptoms started a median of 11 months (range, 1.2-90 months) after organ transplant and consisted primarily of fever, cough, shortness of breath, and malaise or fatigue present for approximately 30 days prior to medical evaluation. All patients had an abnormal chest radiograph and/or computed tomographic scan. Tacrolimus was the main immunosuppressant in all 9 patients, along with prednisone or mycophenolate. Dacluzimab or thymoglobulin had been given around the time of transplant in 6 of 9. None was treated for an episode of acute rejection within 2 months before onset of histoplasmosis, although 2 were on high-dose immunosuppression after recent transplants. Diagnosis was made by culture in 8 of the 9 patients, with positive serum and urine histoplasma antigen tests in all 9 cases. From 1997 to 2001, during a period of relative quiescence of the disease in the general population, the rate of clinical histoplasmosis among SOT patients at UNMC was estimated at 0.11%, whereas during 2002 through the first half of 2004, the rate rose 17-fold to 1.9%. Histoplasmosis can present as a prolonged febrile illness with subacute pulmonary symptoms in a cohort of SOT patients, despite the absence of a regional outbreak.

    Nocardiosis is a rare bacterial infection occurring mainly in patients with deficient cell-mediated immunity. Although disseminated nocardiosis after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a rare complication, it is associated with high mortality. Moreover, after allo-HSCT, nocardiosis may be mistaken for other bacterial or fungal infections because clinical and radiographic findings of pulmonary, cerebral, and cutaneous nocardiosis lesions are non-specific. Here, we report a case of disseminated nocardiosis (caused by Nocardia abscessus) with skin, pulmonary, liver, lymph node, and multiple brain abscesses in a patient after allo-HSCT. The patient initially responded clinically and radiographically to imipenem/cilastin and trimethoprim-sulfamethoxazole therapy. Clinicians should be aware of the possibility of nocardiosis in allo-HSCT recipients who are treated with multiple immunosuppressive agents to control chronic graft-versus-host disease. Accurate diagnosis and identification of disseminated nocardiosis is important to ensure administration of the correct antibiotic regimen. © 2016 John Wiley & Sons A/S.

    .Objective: A patient with a leishmaniasis-Aids co-infection was presented and discussed.
    Methods and results: A 29-year -old soldiier, coming from the Province of San José del Guaviare, Colombia, complained of a weight loss of 18 kgs in the previous ten months as well as a two-month-old cutaneous leision. Elisa and Western blot tests were positive for HIV infection. LT CD4 were 92/mm3. He had a generalized erythematous, psoriasiform dermal lesion,which, upon biopsy, revealed an abundance of phagocytosed microorganisms that stained black with Gomory's technique. Disseminated histoplasmosis was diagnosed. The patient received anti-retroviral therapy and itraconazole, without regression of the lesions. Amphotericin B was beneficial but the lesions recurred several months later, more numerous, nodular and with occurrence in the oral mucosa. Nine months after the initial diagnosis additional skin biopsies and review of the previous biopsies established that the patient had diffuse cutaneous leishmaniasis. The leishmania parasite did not grow in culture. Miltefosine produced marked improvement, but the lesions recurred and were cured finally with 52 Glucantime® injections administered for two months. Presently, the patient remains in good condition 21 months after diagnosis of leishmaniasis.
    Conclusions: Diffuse cutaneous leishmaniasis may be a common clinical manifestation when leishmaniasis and AIDS co-occur. Its treatment is difficult and must include an antiparasitic drug as well as prophylactic,and anti-retroviral therapy. Leishmania amastigotes typically are not Gomory-positive and can be differentiated from Histoplasma by morphology, immunohistochemistry, culture, antibody-specific response and PCR. The leishmaniasis-AIDS co-infection enhances invasive capacity for both causal microorganisms. Increasing case numbers can be expected in Colombia, due to the high frequency of both diseases.

    Cryptococcosis is a potentially fatal fungal disease caused by variants of Cryptococcus neoformans species.  The respiratory tract is the usual portal of entry, with a peculiar predilection to invade the central nervous system.  The skin can be secondarily involved in disseminated infection or be exceptionally involved as primary cutaneous infection by inoculation.  The disease is mostly seen in immunodeficiency states.  The diagnosis is frequently unsuspected in immunocompetent patients. We report a case of disseminated cryptococcal meningitis in an immunocompetent young adult. The cutaneous eruption prompted the accurate diagnosis.  The patient, a 20-year-old female, had fever, cough, headache and intractable vomiting for the past two months and was being managed as a case of tuberculous meningitis. Two weeks after starting antituberculous treatment she developed umbilicated papules on the head and neck region. Necessary laboratory workup identified C. neoformans in cerebrospinal fluid (CSF) and skin specimens.  The titers of cryptococcal antigen were measured in CSF and serum for diagnostic and prognostic purposes.  Anti-fungal treatment resulted in regression of the cutaneous lesions and resolution of systemic complaints. The case highlights the need for high degree of suspicion, especially in healthy young adults, in the diagnosis of cryptococcosis. The cutaneous eruptions can be the first manifestation or a diagnostic clue of enormous significance.

  11. Cutaneous histiocytosis syndromes.

    Science.gov (United States)

    Roper, S S; Spraker, M K

    1985-11-01

    Cutaneous histiocytosis may take two principal forms. It is either a benign proliferative process or a relentless, progressive process with a poor prognosis. In histiocytic medullary reticulosis, histiocytes demonstrate nuclear atypia and the outcome is uniformly fatal. Benign cephalic histiocytosis X causes lesions similar to those of histiocytosis X, but Langerhans' cells are absent. In congenital self-healing histiocytosis X, the Letterer-Siwe-like cutaneous infiltrate contains Langerhans' cells, but the lesions heal spontaneously without treatment. The nodular cutaneous lesions of juvenile xanthogranuloma appear in infancy and resolve without treatment; however, the higher percentage (10%) of associated ocular lesions may lead to glaucoma and blindness. In histiocytosis X, the cutaneous lesions show a marked proliferation of Langerhans' cells, with prognosis dependent on the patient's age and the extent of organ dysfunction. Patients who survive the acute form of the disease may develop diabetes insipidus, growth retardation, pulmonary fibrosis, and biliary cirrhosis. A subtle immunologic defect has been identified in patients with histiocytosis X, yet the pathogenesis of the disease is still speculative. Familial disease occurring in early infancy should be differentiated from complete or partial immunodeficiency syndromes. Guidelines for evaluating patients with cutaneous histiocytosis are reviewed.

    1994-01-01

    A study to screen for the syndrome of presumed ocular histoplasmosis (SPOH) among native populations from three Mexican states was performed. Two of these states, Guerrero and Querétaro, were selected as histoplasmosis is endemic there, whereas Tlaxcala was considered a control, due to the absence of reported cases. A total of 253 individuals were submitted to ocular fundus examination to obtain evidence of SPOH. A high percentage of positive reactors to histoplasmin skin test (ST) was observed in Guerrero (83%) and Querétaro (53%), whereas in Tlaxcala positive ST were almost absent (2.04%). Only five individuals had retinal lesions, although these lesions were not characteristic of the syndrome. Stimulation of these individual's cells showed different patterns in the histoplasmin-induced lymphocyte transformation response, and two out of five individuals with retinal lesions presented a stimulated response, as well as three controls without lesions. Histocompatibility antigens (HLA) were determined in a sample of each population and no particular allele, including HLA-B7, was found to be related to SPOH as reported in the USA; however, HLA-B22 was found in three individuals who developed pulmonary histoplasmosis. Results do not provide clinical evidence or data on specific HLA risk factors, for the presence of SPOH in the population studied.

    Histoplasmosis is considered the most important systemic mycosis in Mexico, and its diagnosis requires fast and reliable methodologies. The present study evaluated the usefulness of PCR using Hcp100 and 1281-1283(220) molecular markers in detecting Histoplasma capsulatum in occupational and recreational outbreaks. Seven clinical serum samples of infected individuals from three different histoplasmosis outbreaks were processed by enzyme-linked immunosorbent assay (ELISA) to titre anti-H. capsulatum antibodies and to extract DNA. Fourteen environmental samples were also processed for H. capsulatum isolation and DNA extraction. Both clinical and environmental DNA samples were analysed by PCR with Hcp100 and 1281-1283(220) markers. Antibodies to H. capsulatum were detected by ELISA in all serum samples using specific antigens, and in six of these samples, the PCR products of both molecular markers were amplified. Four environmental samples amplified one of the two markers, but only one sample amplified both markers and an isolate of H. capsulatum was cultured from this sample. All PCR products were sequenced, and the sequences for each marker were analysed using the Basic Local Alignment Search Tool (BLASTn), which revealed 95-98 and 98-100 % similarities with the reference sequences deposited in the GenBank for Hcp100 and 1281-1283(220), respectively. Both molecular markers proved to be useful in studying histoplasmosis outbreaks because they are matched for pathogen detection in either clinical or environmental samples.

The existence of epidemiologic link, four patients with clinical signs suggestive of histoplasmosis and mycological confirmation has made that all 35 individuals involved to the cave visit were subjected to serological evaluation. By DI, we observed reactivity against H. capsulatum antigen in a single serum examined nearly 20 days after exposure to fungal propagules. On the other hand, IB showed reactivity against H and M fractions in 50% of samples evaluated. The analysis of the second sample batch, collected two months after the exposure showed that 96.7% were reactive by DI with antibodies titers ranging from 1 to 16 and 100% of reactivity against H and M fractions, by IB, suggesting an acute infection. The analysis of the overall agreement between the methods showed to be reasonable (κ = 0.37). This study confirms the importance and efficacy of more sensitive methodologies, such as IB assay, to early elucidation of disease, especially in cases of patients without mycological information.

    2013-01-01

    Full Text Available Calciphylaxis is a devastating disorder with a mortality rate of 80% due to sepsis and organ failure. Hallmarks of this rare disease are arteriolar media calcification, thrombotic cutaneous ischemia, and necrotic ulcerations. Different mechanisms of vascular calcification can lead to calciphylaxis. Early diagnosis by deep cutaneous ulcer biopsy is most important for prognosis. Here, dermatologists play a significant role although treatment usually needs an interdisciplinary approach. Surgical procedures had been the cornerstone of treatment in the past including parathyroidectomy, but recently new medical treatments emerged aiming to normalize disturbances of minerals to reduce the serum concentration of sodium phosphate and to prevent precipitation and calcification. Multimodal therapy is warranted but only aggressive surgical debridement of cutaneous ulcers has shown significant outcome improvement.

    It is important for dermatologists to be aware of cutaneous changes related to religious practices to help in their recognition and management. The anatomic location of cutaneous lesions associated with friction from praying varies based on religious practice. Allergic contact dermatitis from products and substances commonly used in worshipping also vary by religion. Some religious practices may render individuals prone to infections that manifest on the skin. Tattoos of godly figures also may adorn the body. Religious practices also have been implicated in cases of urticaria, köbnerization, and leukoderma. This article reviews the clinical presentation of some of the most common cutaneous changes that occur in individuals who practice the following religions: Christianity, Islam, Judaism, Hinduism, and Sikhism.

    Multifocal cutaneous histiocytic lesions were recognized in 9 dogs. Clinically, the dogs had multiple erythematous plaques or nodules in the skin (1 to 5 cm diameter). Histologically, the lesions were comprised of dermal or pannicular infiltrates of large histiocytic cells, with varying numbers of other inflammatory cells intermixed. By electron microscopy, the cells resembled those of canine cutaneous histiocytoma. The lesions seemed to wax and wane and appeared in new sites, regardless of treatment. The dogs ranged in age from 2 to 13 years; 7 dogs were under 6 years of age. Both sexes and various breeds were represented. An infectious agent could not be identified.

    Full Text Available Sarcoidosis involves abnormal collections of inflammatory cells (granulomas which may form as nodules in multiple organs. 90% of affected patients have respiratory tract abnormalities. We present a 61-year-old male with sarcoidosis who was admitted for respiratory distress. Fibrosing mediastinitis was seen in the chest computograph. Management was conservative and included steroids, antibiotics, and oxygen therapy. Sarcoidosis and fibrosing mediastinitis are rare. Fibrosing mediastinitis is more commonly seen with histoplasmosis. We explore the clinical similarities between histoplasmosis and sarcoidosis. We also explore the potential cause and effect relationship and workup for each disease entity.

    Neurohistoplasmosis is a rare disease, most prevalent in immunosuppressed patients, secondary to disseminated disease with a high mortality rate when diagnosis and treatment are delayed. We report a previously healthy 12 year old girl, from a bat infested region of Tucuman Province, Argentine Republic, who developed meningoencephalitis due to Histoplasma capsulatum. Eighteen months prior to admission the patient started with headaches and intermittent fever. The images of the central nervous system showed meningoencephalitis suggestive of tuberculosis. She received antibiotics and tuberculostatic medications without improvement. Liposomal amphotericin B was administered for six weeks. The patient's clinical status improved remarkably. Finally the culture of cerebral spinal fluid was positive for micelial form of Histoplasma capsulatum. The difficulties surrounding the diagnosis and treatment of neurohistoplasmosis in immunocompetent patients are discussed in this manuscript, as it also intends to alert to the presence of a strain of Histoplasma capsulatum with affinity for the central nervous system.

Delusional infestation is a rare monosymptomatic hypochondriacal psychosis according to The Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5; American Psychiatric Association, 2013. It can be a primary disorder or associated with an underlying psychological or physical disorder. It commonly presents as delusional parasitosis, and less than 1% may be fungi related. We present this case as it is a rare presentation of a rare condition. Case Presentation. Our patient is a 60-year-old Caucasian man who presented with a 7-year history of delusional infestation manifested as a disseminated fungal infection. He had previously been reviewed by multiple physicians for the same with no systemic illness diagnosed. After multiple reviews and thorough investigation we diagnosed him with a likely delusional disorder. As is common with this patient cohort he refused psychiatric review or antipsychotic medication. Conclusion. A delusion of a disseminated fungal infestation is a rare condition. It is exceedingly difficult to treat as these patients often refuse to believe the investigation results and diagnosis. Furthermore, they either refuse or are noncompliant with treatment. Multidisciplinary outpatient evaluation may be the best way to allay patient fears and improve treatment compliance.

    Mucormycosis is a rare but serious sequelae of penetrating trauma [1-5]. In spite of aggressive management, mortality remains high due to dissemination of infection. We completed a review of literature to determine the most optimal treatment of cutaneous mucormycosis which occurs secondary to penetrating trauma. We completed a review regarding the management of mucormycosis in trauma patients. We selected a total of 36 reports, of which 18 were case-based, for review. Surgical debridement is a primary predictor of improved outcomes in the treatment of mucormycosis [3,6,7]. Anti-fungal therapy, especially lipid soluble formulation of Amphotericin B, is helpful as an adjunct or when surgical debridement has been maximally achieved. Further research is needed to fully evaluate the impact of topical dressings; negative pressure wound therapy is helpful. An aggressive and early surgical approach, even at the expense of disfigurement, is necessary to reduce mortality in the setting of cutaneous mucormycosis that results from penetrating trauma [4,8,9]. Anti-fungal therapy and negative pressure wound therapy are formidable adjuncts. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Cutaneous tuberculosis is a chronic infectious disease caused by Mycobacterium tuberculosis. It is not very frequent and particularly difficult to diagnose. It incidence ranges between 1.5 and 4% of all extrapulmonary tuberculosis, according to bibliography. The clinic presentations depend on the arrival via of the bacillus to the skin, the patient's immune state and the environment. We show a cutaneous tuberculosis on a child with chronic dermatologic lesions, with torpid evolution, without response to treatments; the skin biopsy showed caseous granulomas. The aim is to show a patient with an infrequent clinic presentation of this disease, to emphasize the importance of an early recognition and treatment, avoiding the appearance of complications and sequels.

    A western blot (WB) test was evaluated for detection of antibodies against native glycosylated and chemically deglycosylated M and H antigens of Histoplasma capsulatum in serum obtained from patients during the acute phase of pulmonary histoplasmosis that occurred during an outbreak. Of 275 serum samples tested by immunodiffusion and complement fixation (CF) samples from 40 patients affected during this outbreak and from 37 negative controls were tested by WB test. A group of patients whose sera were negative for CF antibodies and precipitins early in the acute stage of histoplasmosis but who all seroconverted during convalescence 6 weeks later were tested with the WB test. Antibodies against untreated H and M antigens were detected at a 1:100 dilution by WB test in 45% of the 20 acute-phase serum samples and in all 20 of the convalescent-phase specimens. The WB test’s sensitivity for acute-phase specimens increased to 90% (18 of 20 specimens) when H and M antigens were treated by periodate oxidation to inactivate susceptible carbohydrate epitopes. When native glycosylated antigens were used in the WB test, positive reactions were observed in negative control serum specimens (3 of 37 specimens; 8%) and in serum specimens obtained from asymptomatic persons screened as part of the outbreak investigation (13 of 20 specimens; 65%). These positive reactions were also attributed to glycosidic epitopes since the specificity of the WB test increased from 78 to 100% when periodate-treated H and M antigens were used. WB test with deglycosylated H and M antigens of histoplasmin provides a rapid, sensitive, and specific test to diagnose acute pulmonary histoplasmosis before precipitins can be detected.

    We performed a meta-analysis of diagnostic data to evaluate the performance of Histoplasma antigen detection tests for diagnosing histoplasmosis. We included all studies involving human subjects that assessed the performance of any antigen detection test for histoplasmosis in urine or serum by carrying out an exhaustive and reproducible search of the literature between 1980 and 2014 from four databases. Quality of the articles was assessed, and meta-analysis was performed under the random effects model, calculating sensitivity, specificity, likelihood and odds ratios, and ROC curve using Meta-DiSc(es). Nine out of a total of 23 studies met strict quality criteria and were therefore included. The overall sensitivity for antigen detection in serum and urine was 81% (95% CI 78-83%), while specificity was 99% (95% CI 98-99%). Sensitivity for antigenuria and antigenemia was 79% (95% CI 76-82%) and 82% (95% CI 79-85%), respectively; specificity values were 99% (95% CI 98-100%) in urine and 97% (95% CI 96-98%) in serum. The positive and negative likelihood ratios were 49.5 (95% CI 20.7-118.7) and 0.19 (95% CI 0.14-0.26), respectively, while the diagnostic OR was 362 (95% CI 121.2-1080.3) and area under the curve was 0.99. In conclusion, the performance of Histoplasma antigen detection assay of urine was not significantly different from that of blood, indicating that antigenuria and antigenemia have equal diagnostic value in histoplasmosis.

We report the case of an immunocompetent patient presenting with a two-month history of cough, dyspnea, and fever. The patient resided in a rural area. Imaging tests revealed extensive pneumonitis and pulmonary fibrosis. On the basis of direct mycological examination, culture, and serological testing, we made a diagnosis of concomitant histoplasmosis and paracoccidioidomycosis. The patient presented arterial hypotension that was diagnostic of adrenocortical insufficiency. Although the pulmonary fibrosis and pneumonia were irreversible, the clinical condition of the patient improved after antifungal treatment. This was an exceptional case of two pulmonary fungal infections occurring simultaneously in the same patient.

    In patients with acquired immunodeficiency syndrome (AIDS), advanced immunosuppression is associated with atypical presentation of dermatological conditions. Our patient presented with a single crusted plaque over the lower lip and large tender cervical lymphadenopathy. The enzyme-linked immunosorbent assay for human immunodeficiency virus was found to be positive, and his CD4+ lymphocyte cell count was 4 cells/mm(3). The presence of multiple histoplasma spores in the biopsies from the crusted plaque over lip and cervical lymph node helped in the confirmation of the diagnosis of histoplasmosis, and the patient showed significant improvement within two months of treatment with conventional injection amphotericin B initially followed by oral itraconazole.

    Full Text Available Legionella pneumophila is the most common cause of legionellosis and is one of the organisms causing atypical pneumonia. We report the presentation of disseminated intravascular coagulation (DIC and skin rash in a single case of severe Legionella pneumonia. The unique clinical presentation of a diffuse rash diagnosed as purpura fulminans and the unpredictable variations encountered during the diagnostic work-up of the case make this write-up crucial. This article synthesizes all reported cases of L. pneumonia associated with cutaneous manifestations as well as cases presenting with DIC. Furthermore, this manuscript illustrates the correlation between cutaneous and coagulopathic manifestations, and morbidity and mortality from L. pneumonia.

    The impact of highly active antiretroviral therapy (HAART) on the epidemiology of AIDS-associated histoplasmosis in the past decade is poorly defined. Among 100 patients with histoplasmosis in an endemic region between 2000 and 2009, 42 patients were immunocompetent, 32 were infected with HIV, and 26 were non-HIV-immunocompromised patients. The percentage with HIV decreased 67% in 2000-2001 to 18% in 2008-2009 (P = .004), while the proportion of non-HIV immunocompromised patients increased, 8% to 41% (P = .14). Histoplasma antigen was the most sensitive test (73%), whereas potassium hydroxide examination of clinical specimens was the least sensitive test (33%) in all 3 groups. Bronchoalveloar fluid culture (74%) had the highest yield among the cultures. The relapse rate was higher in HIV-infected patients compared to the other 2 groups (P = .04). The epidemiology of histoplasmosis in our endemic area has changed during the era of HAART. Organ transplantation and increasing use of immunosuppressive agents for chronic inflammatory conditions in non-HIV patients now account for most of the cases of histoplasmosis.

    The bioactive lipid mediator leukotriene B4 (LTB4) greatly enhances phagocyte antimicrobial functions against a myriad of pathogens. In murine histoplasmosis, inhibition of the LT-generating enzyme 5-lypoxigenase (5-LO) increases the susceptibility of the host to infection. In this study, we investigated whether murine resistance or susceptibility to Histoplasma capsulatum infection is associated with leukotriene production and an enhancement of in vivo and/or in vitro antimicrobial effector function. We show that susceptible C57BL/6 mice exhibit a higher fungal burden in the lung and spleen, increased mortality, lower expression levels of 5-LO and leukotriene B4 receptor 1 (BLT1) and decreased LTB4 production compared to the resistant 129/Sv mice. Moreover, we demonstrate that endogenous and exogenous LTs are required for the optimal phagocytosis of H. capsulatum by macrophages from both murine strains, although C57BL/6 macrophages are more sensitive to the effects of LTB4 than 129/Sv macrophages. Therefore, our results provide novel evidence that LTB4 production and BLT1 signaling are required for a histoplasmosis-resistant phenotype.

    The adhesive cutaneous pharmaceutical forms aimed to local action release the drug substance in view of a dermatological, traumatological, antirheumatic, cosmetic action. Two such preparations were obtained and their stability, consistency and pH were determined. The "in vitro" tests of their bioavailability revealed the dynamics of calcium ions release according to the associations of each preparation. The bioavailability determined by evaluating the pharmacological response demonstrated the antiinflammatory action obtained by the association of calcium ions with the components extracted from poplar muds. The therapeutical efficiency of the studied preparations has proved in the treatment of some sport injuries.

    Full Text Available Cutaneous leishmanasis (CL may present with unusual clinical variants such as acute paronychial, annular, palmoplantar, zosteriform, erysipeloid, and sporotrichoid. The zosteriform variant has rarely been reported. Unusual lesions may be morphologically attributed to an altered host response or owing to an atypical strain of parasites in these lesions. We report a patient with CL in a multidermatomal pattern on the back and buttock of a man in Khozestan province in the south of Iran. To our knowledge, this is the first reported case of multidermatomal zosteriform CL. It was resistant to conventional treatment but responded well to a combination of meglumine antimoniate, allopurinol, and cryotherapy.

    Abstract Background: Mucormycosis is a rare, aggressive, and life-threatening infection that is caused by organisms belonging to the order Mucorales. It is usually acquired through direct means and virtually always affects immunocompromised patients with the port of entry reflecting the site of infection, in this case, cutaneous. Unlike other mucormycoses, patients affected by Apophysomyces elegans (A elegans) are known to be immunocompetent. This locally aggressive disease penetrates through different tissue plains invading adjacent muscles, fascia, and even bone causing extensive morbidity and may prove fatal if treated inadequately. Cutaneous mucormycosis is associated with disruption of cutaneous barriers such as trauma. However, rarely, it may be iatrogenic. No cases have been previously reported postcosmetic surgery, especially one that is so commonly performed, lipofilling. Case Report: The patient is a, previously healthy, 41-year-old middle-eastern female who was admitted to the plastic surgery department 17 days after undergoing cosmetic surgery. She suffered from extensive tissue inflammation and necrosis in both gluteal regions. Following admission, she was initially started on empirical antimicrobial therapy which was changed to an antifungal agent, voriconazole, when preliminary microbiological results showed filamentous fungi. This was discontinued and liposomal amphotericin B was commenced when further mycological analysis identified A elegans. Furthermore, she underwent a total of 10 sessions of extensive debridement to the extent that portions of the sacrum and left femoral head became exposed. Her clinical status and wounds improved with the appropriate management and she remained an inpatient for 62 days. Subsequently, she had defects in both gluteal regions which required reconstructive surgery. Conclusion: A elegans is an uncommon cause of iatrogenic cutaneous mucormycosis. A high index of clinical suspicion is required, especially in the

    Full Text Available The term performativity and its inflexions have been applied to several concepts in the field of educational research. In this study, we trace the dissemination of the word performativity and its correlates, starting from the meanings attributed to the term by Stephen Ball, in his analysis of contemporary educational policies, but also using the theories of Jacques Derrida and Judith Butler, who used these terms to refer to social processes of signification and identification, and also references made to the term in studies of Anthropology, Arts, Political Science, Linguistics, Philosophy and Physics. On top of that, we researched studies in the field of academic education, examining articles from journals and other periodicals published over the last five years, in order to discuss the various meanings attributed to the term within the educational field. We present, in this paper, a synthesis of our investigations, highlighting the affirmations, negations and truth effects that can be construed from the use of these terms in educational research, in particular when approaching current educational policies.

    Mantle cell lymphoma (MCL) commonly involves extranodal sites, usually as a manifestation of disseminated disease. In rare cases, MCLs may arise as a primary tumor in the skin. Blastoid mantle cell lymphoma (BV-MCL) is a rare variant and has a more aggressive clinical course. The phenotype of BV-MCL is characterized as CD20+, CD5+, cyclin D1+, CD23-, and CD10-. Interphase fluorescence in situ hybridization shows a characteristic t(11;14) fusion pattern. We report a case of a BV-MCL arising in skin as primary cutaneous MCL with the characteristic immunophenotype and translocation.

    A 28-year-old woman presented with reddish raised, shiny lesions over the face and ears present for the past 3 years. Four years ago, she developed in her left axilla a nodule that became fluctuant and tender, which ruptured to discharge seropurulent material. It subsided after the patient had received antibiotics for 6 months, leaving puckered scarring. There was no history of antituberculous treatment. After 1 year, she developed papulonodular lesions on her face, nose, and ears. There was now a history of malaise, fever, dry cough, and anorexia and weight loss for the past 2 months. The patient was fully vaccinated in childhood, including against varicella infection. The general physical examination revealed lymphadenopathy involving cervical, axillary, and inguinal lymph nodes 0.5 x 0.5 cm to 1 x 1.5 cm, firm in consistency, and nontender. They were discrete except in the left axilla where multiple matted lymph nodes were present with overlying scarring and a papule. Her systemic examination was normal. Cutaneous examination showed a shiny erythematous plaque 3x2 cm with central atrophy and scarring on the face (Figure). It was comprised of multiple shiny nontender soft papules arranged in annular configuration. Similar discrete papules and nodules with adherent fine scaling were seen bilaterally on the alar prominence of the nose, lower lip, and post-auricular area. On diascopy, apple jelly nodules were seen. The hemogram, liver function tests, and renal function tests were normal, except for an elevated erythrocyte sedimentation rate. The Mantoux test showed erythema and an induration of 20 x 20 cm. A posteroanterior view on the chest x-ray showed fibrotic changes suggestive of pulmonary tuberculosis. Ultrasonography of the abdomen and pelvis showed no tubercular foci. Human immunodeficiency virus serology by enzyme-linked immunosorbent assay with 3 different kits was nonreactive. Histopathology from a nodule showed a focally thinned-out epidermis with

    We describe the case of a patient with cutaneous diphtheria caused by toxigenic Corynebacterium ulcerans who developed a right hand flexor sheath infection and symptoms of sepsis such as fever, tachycardia, and elevated C-reactive protein, after contact with domestic cats and dogs, and a fox. We summarise the epidemiology, clinical presentation, microbiology, diagnosis, therapy, and public health aspects of this disease, with emphasis on improving recognition. In many European countries, C ulcerans has become the organism commonly associated with cutaneous diphtheria, usually seen as an imported tropical disease or resulting from contact with domestic and agricultural animals. Diagnosis relies on bacterial culture and confirmation of toxin production, with management requiring appropriate antimicrobial therapy and prompt administration of antitoxin, if necessary. Early diagnosis is essential for implementation of control measures and clear guidelines are needed to assist clinicians in managing clinical diphtheria. This case was a catalyst to the redrafting of the 2014 national UK interim guidelines for the public health management of diphtheria, released as final guidelines in March, 2015.

Patients′ bio-data and clinical information were obtained from records. Results : Twenty males and seven females presented with 6 months to 6 years histories of varying symptoms of slow growing facial swellings, nodules, subcutaneous frontal skull swelling, proptosis, nasal blockage, epistaxis, discharging leg sinuses, flank mass, convulsion and pain. Of the 27 patients, four gave antecedent history of trauma, two had recurrent lesions which necessitated maxilectomy, two presented with convulsion without motor dysfunction while one had associated erosion of the small bones of the foot. None of the patients had debilitating illnesses such as diabetes mellitus, tuberculosis, and HIV infection. Tissue histology revealed histoplasmosis (10, mycetoma (9, subcutaneous phycomycosis (6, and phaeohyphomycosis (2. Conclusion : Deep mycoses may present primarily as cutaneous lesions in immunocompetent persons and often elicit distinct histologic inflammatory response characterized by granuloma formation. Diagnosis in resource constraint setting can be achieved with tissue stained with PAS and GMS which identifies implicated fungus. Clinical recognition and adequate knowledge of the pathology of these mycoses may reduce attendant patient morbidity.

    Primary cutaneous peripheral T-cell lymphomas (PTL), unspecified, are rare lymphomas, with a poor prognosis. They grow and disseminate rapidly, leading to widespread disease. We report a case of PTL, unspecified occurring on the nose. Despite its aggressive histology, this tumour behaved indolently. It is remarkably similar, clinically and histologically, to four recently described cases that occurred on the ear.

    Full Text Available Cutaneous polyarteritis nodosa (CPAN is a rare form of cutaneous vasculitis that involves small and medium sized arteries of the dermis and subcutaneous tissue without systemic involvement. It presents with tender subcutaneous nodules, digital gangrene, livedo reticularis and subcutaneous ulcerations. The diagnosis is by skin biopsy and characteristic pathologic feature is a leukocytoclastic vasculitis in the small to medium-sized arterioles of the dermis. We report a rare case of benign cutaneous PAN in a 14-year-old girl who presented with history of fever, subcutaneous nodules with cutaneous ulcer and digital gangrene. The skin biopsy showed leukocytoclastic vasculitis with fibrinoid necrosis in the dermal vessels. She received treatment with steroids and lesions resolved completely over a period of month.

    Radiotherapy plays an important role in the treatment of cutaneous lymphomas. In the treatment of Mycosis fungoides, total skin electron beam radiation therapy is efficient for patients with limited and superficial forms of the disease. Radiotherapy is also efficient for the locally advanced forms of non-epidermo-tropic lymphomas. The palliative radiotherapy is indicated for advanced, nodular and treatment resistant forms of cutaneous lymphomas and for voluminous lymphadenopathies. (authors)

    Sporotrichoid cutaneous leishmaniasis is due to dissemination of amastigotes via the lymphatics to the subcutaneous tissues. A comparison was made between the potential to disseminate by this route of 2 parasites of different zymodemes in Sudan and Saudi Arabia. In Sudan cutaneous leishmaniasis...... is caused by Leishmania major zymodeme LON-1, and in Saudi Arabia by L. major LON-4. Sporotrichoid leishmaniasis was significantly more common in Sudan, occurring in 23% of patients compared with 10% in Saudi Arabia. Lymph node involvement was slightly more prevalent in the Sudan. Clinical and pathological...... differences between subcutaneous nodules, particularly when they ulcerate, and multiple primary cutaneous lesions are described and treatment of localized and sporotrichoid leishmaniasis is discussed. The pathological features of the primary lesions in the Sudan and Saudi Arabia were similar....

  6. Blood culture as a parameter of treatment effectiveness in experimental histoplasmosis of the hamster Hemocultivos como parametro de la eficacia del tratamiento de la histoplasmosis experimental en hamster

    Full Text Available The aim of this study was to determine the value of blood culture as a parameter of treatment effectiveness in experimental histoplasmosis. A total of thirty five hamsters, weighing approximately 120g, were inoculated intracardiacly with 0.1 ml of a suspension containing 4 x 10(7 cells/ml of the yeast phase of H. capsulatum. Treatments were started one week after the infection and lasted for 3 weeks. The azoles, (itraconazole, saperconazole and fluconazole were administered once a day by gavage, at a dose of 8 mg/kg; Amphotericin B was given intraperitonealy every other day at a dose of 6mg/kg. Blood samples (1 ml were obtained by heart punction from the 4th day after infection and were seeded in Sabouraud honey-agar and BHI-agar. The hamsters that survived were killed one week after treatment completion and the following criteria were considered for treatment evaluation: 1 rate of spontaneous death, at the end of the experience; 2 microscopic examination of Giemsa smears from liver and spleen and 3 determination of CFU in spleen cultures. Amphotericin B was the most effective drug, with negative blood cultures at day 20, negative spleen cultures in all cases and all the animals survived until the end of the study. Fluconazole was the less effective drug, blood cultures were positive during the whole experience, spleen cultures showed a similar average of CFU when compared with the control animals and 42.8% of these animals died. Saperconazole and itraconazole showed a similar activity, with survival of all hamsters and negative blood cultures at 23 and 26 days respectively. Blood culture seems to be valuable parameter for treatments' evaluation in experimental histoplasmosis of the hamster.El propósito de esta investigación fue determinar el valor de los hemocultivos para juzgar la eficacia de los tratamientos en la histoplasmosis experimental.

    Severe cases of itraconazole-induced hepatotoxicity have been reported; however, these events are thought to occur very rarely. The available literature is comprised largely of individual case reports and small series that do not report the itraconazole serum concentration at the time of the severe adverse event or apply an objective scale to assess probability of the event being related to drug exposure. We report a case of severe hepatotoxicity after 6 months of itraconazole therapy for histoplasmosis, resulting in acute hepatic failure (aspartate transaminase >20× and alanine transaminase >15× upper limit normal), in the setting of therapeutic serum concentrations (5 mg/mL). Both the Naranjo probability scale and the Roussel Uclaf causality assessment method were used to assess the probability of a causality relationship showing a "probable" and "highly probable" association with itraconazole exposure, respectively. The available literature describing severe hepatotoxicity resulting in hepatic failure associated with itraconazole is also reviewed.

    The purpose of this work is to report the isolation of Histoplasma capsulatum, etiologic agent of histoplasmosis, from soil in sites inhabited by bats and chicken in the Island of Youth, Cuba. The fungus was cultured from four species of cave dwelling bats too. The identification of H. capsulatum was done by mycelial to yeast conversion and exoantigen test. It is pointed out the epidemiological value of some of these isolations in caves of great importance from the archaeological, speleological or tourist point of view, and the potential risk that they represent to human health. The authors conclude with some recommendation to prevent the infection with H. capsulatum in people who have to keep in contact with those environments.

    A 7-year-old intact male mixed dog was presented with a history of acute and progressive paraparesis. Abnormal clinical signs consisted of non-ambulatory paraparesis, hind limbs hypertonia and severe thoracolumbar pain. Magnetic resonance imaging demonstrated an isointense in T1 and T2 WI epidural lesion, with good contrast enhancement, extending from T-10 to T-13. Laminectomy was carried out to remove the epidural mass. Histological examination revealed a pyogranulomatous lesion characterized by numerous macrophages containing yeast-like Grocott and PAS-positive bodies. Immunohistochemistry and PCR performed on formalin-fixed paraffin-embedded tissue confirmed Histoplasma capsulatum as the causative agent. H. capsulatum has a worldwide distribution in temperate and subtropical climates but its presence as an autochthonous fungus in Europe is now recognized. To the authors' knowledge this is the first report of canine histoplasmosis in Italy with lesion confined to the central nervous system.

A non-diabetic patient presented with adrenal histoplasmosis and UTI leading to adrenal failure. No immediate cause of immunosuppression was found, HIV, HTLV screening were negative. A CD4 count was done and the patient was found to be having non-HIV AIDS (idiopathic CD4 lymphocytopenia. He was treated and discharged. Few months later the patient presented again with adrenal failure and pulmonary tuberculosis. Adrenal FNAC showed persisting adrenal histoplasmosis.

    We determined the value of culture and serological tests used to diagnose histoplasmosis. The medical records of 391 histoplasmosis patients were analyzed. Diagnosis of the mycosis was assessed by culture, complement fixation, and immunodiffusion tests; 310 patients (79.5%) were male, and 184 patients (47.1%) were infected with human immunodeficiency virus (HIV). Positivity value for cultures was 35.7% (74/207), reactivity of serological tests was 95.2% (160/168), and a combination of both methodologies was 16.9% (35/207) for non-HIV patients. Positivity value for cultures was 75.0% (138/184), reactivity of serological tests was 92.4% (85/92), and a combination of both methodologies was 26.0% (48/184) for HIV/acquired immunodeficiency syndrome (AIDS) patients; 48.1% (102/212) of extrapulmonary samples from HIV/AIDS patients yielded positive cultures compared with 23.1% (49/212) in non-HIV patients. Lymphocyte counts made for 33.1% (61/184) of HIV/AIDS patients showed a trend to low CD4+ numbers and higher proportion of positive cultures. These results indicate that culture is the most reliable fungal diagnostic method for HIV/AIDS patients, and contrary to what is generally believed, serological assays are useful for diagnosing histoplasmosis in these patients.

    Primary cutaneous mucormycosis is a rare but often lethal severe fungal infection, which usually occurs in immunocompromised patients. We report a case of primary cutaneous mucormycosis caused by Mucor irregularis in an elderly patient. Seven months after the surgical dissection of the involved skin, cutaneous mucormycosis recurred at the peripheral edge of the skin graft. Shortly subsequent to the administration of liposomal amphotericin B, the remaining skin lesion was excised again. M. irregularis is rarely but increasingly reported as a cause of mucormycosis in immunocompetent individuals, especially in Asian farmers. M. irregularis may be largely disseminated in the soils of Asia and thus the trivial trauma at the time of farm work may be a trigger for the onset. These cases tend to leave severe cosmetic damage even in healthy individuals, although the vital prognosis is not affected. © 2014 Japanese Dermatological Association.

    Mobile devices integrating wireless short-range communication technologies make possible new applications for spontaneous communication, interaction and collaboration. An interesting approach is to use collaboration to facilitate communication when mobile devices are not able to establish direct communication paths. Opportunistic networks, formed when mobile devices communicate with each other while users are in close proximity, can help applications still exchange data in such cases. In opportunistic networks routes are built dynamically, as each mobile device acts according to the store-carry-and-forward paradigm. Thus, contacts between mobile devices are seen as opportunities to move data towards destination. In such networks data dissemination is done using forwarding and is usually based on a publish/subscribe model. Opportunistic data dissemination also raises questions concerning user privacy and incentives. Such problems are addressed di?erently by various opportunistic data dissemination techniques. ...

    2014-09-01

    Until recently, treatment options for patients with metastatic melanoma were very limited. This landscape has evolved dramatically since the discovery of activating mutations in the BRAF gene in ~45% of cutaneous melanomas. Vemurafenib, dabrafenib, and trametinib have all received regulatory approval for the treatment of metastatic melanoma patients with a BRAF(V600) mutation. Based on the necessity to document the presence of a BRAF(V600) mutation to prescribe these agents, molecular testing is now the standard of care in this disease. However, the options and rationale for testing are evolving rapidly due to an improved understanding of the molecular drivers and heterogeneity of melanoma. Such testing may identify rational combinatorial approaches to prevent or overcome resistance for the approved BRAF inhibitors. In addition, new clinical strategies have been identified for a number of other molecular changes that are detected in this disease, including somatic changes in NRAS, PTEN, CDKN2A, and c-KIT, among others. This review summarizes the current understanding of the genetic landscape of mutations in melanoma, their associations with clinicopathological features, and their implications for clinical testing and treatment.

    2011-08-01

    Full Text Available Abstract Introduction Severe histoplasmosis is known to be among the AIDS-defining opportunistic infections affecting patients with very low CD4 cell counts in histoplasmosis-endemic areas. Histoplasma capsulatum var. duboisii is common in West and Central Africa, where it occurs in both HIV/AIDS and non-HIV patients. Few cases of life-threatening histoplasmosis in immune-competent individuals have been reported worldwide. Case report We describe a case of pulmonary histoplasmosis diagnosed on the basis of autopsy and histological investigations. A 15-year old East African immune-competent boy with a history of smear-positive tuberculosis and a two-year history of rock cutting presented to our hospital with chronic productive cough, fever, and massive unilateral consolidation. At the time of presentation to our hospital, this patient was empirically treated for recurrent tuberculosis without success, and he died on the seventh day after admission. The autopsy revealed a huge granulomatous lesion with caseation, but no acid-fast bacilli were detected on several Ziehl-Neelsen stains. However, periodic acid-Schiff staining was positive, and the histological examination revealed features suggestive of Histoplasma yeast cells. Conclusion Severe pulmonary histoplasmosis should be considered in evaluating immune-competent patients with risk factors for the disease who present with pulmonary symptoms mimicking tuberculosis.

    Beau lines are transverse, band-like depressions extending from one lateral edge of the nail to the other and affecting all nails at corresponding levels (1). Onychomadesis is considered an extreme form of Beau line with subsequent separation of the proximal nail plate from the nail bed. Both fall along a spectrum of nail plate abnormalities that occur secondary to temporary nail matrix arrest (NMA). Various systemic and dermatologic conditions have been reported in association with onychomadesis (2-7) (Table 1). Nail changes can affect all or some of the nails and both the fingernails and toenails; however, fingernails are more frequently affected. The severity of the nail changes varies depending on the underlying cause, its duration, and environmental factors (8). We present a case of onychomadesis following cutaneous leukocytoclastic vasculitis (CLCV). A 61-year-old woman presented to the Dermatology Clinic complaining of a purpuric rash that began on her lower extremities and rapidly progressed to her abdomen and upper extremities over the previous five days. Her medical history was remarkable for hypertension and diet-controlled diabetes mellitus. Her medications included enalapril, which she had been taking for the past four years. On three consecutive days before the skin eruption, the patient took oral diclofenac sodium for hip pain. A clinical examination revealed non-blanching petechial rash on the legs, abdomen, and upper limbs up to the elbow (Figure 1, A) with leukocytoclastic vasculitis on biopsy (Figure 1, B). Direct immunofluorescence was negative. Laboratory investigations revealed a white blood cell count of 14.5 × 109/L with a normal differential count, and a platelet count of 380 × 109/L. Westergren erythrocyte sedimentation rate was 65 mm/1st h, and C reactive protein was at 8.5 mg/dL. Antinuclear antibodies, rheumatoid factor, immune complexes, and cryoglobulinemia were negative, as were B and C hepatitis virus serological tests. Her renal

    1991-09-01

    'Ageing is a multistep, multifaceted, time-dependent phenomenon characterized by the decreased ability of a system to respond to exogenous and endogenous stress from either physical, chemical or biologic agents'. Cutaneous ageing provides a visible model of the interaction between endogenous (intrinsic) factors and exogenous (extrinsic) factors. In skin, the principal extrinsic-factor is ultraviolet light (UV) which is responsible for the constellation of changes termed photoageing. In recent years, much interest has been directed towards defining the ageing processes in skin and excellent comprehensive reviews have been compiled. This review aims to highlight several areas of developing knowledge, and focuses on the potential importance of environmental changes as they influence skin ageing and carcinogenesis. Repeated reference to the effects of UV on the skin are inevitable in any review of skin ageing and this is scarcely surprising as the skin contains many cells as well as subcellular and extracellular chromophores which are capable of absorbing energy within the UV spectrum. Cellular chromophores include among others keratinocytes, melanocytes, Langerhans cells, dermal fibroblasts and mast cells. Subcellular chromophores include keratin, melanin, collagen, elastin and a number of proteins, lipids and steroids (such as vitamin D). Urocanic acid, a photoisomerization product of the amino-acid histidine, may provide some limited photoprotection and some believe it to be important in UV induced immunosuppression. Understanding events at the molecular and biochemical level has unfortunately not been paralleled by clinical advances and the common, troublesome skin-problems of old age such as cancer, xerosis and pruritus remain a major cause of morbidity and yet are poorly explained.

    Full Text Available Importance. Cutaneous and systemic plasmacytosis are rare conditions of unknown etiology with characteristic red-brown skin lesions and a mature polyclonal plasma cell infiltrate within the dermis. Perineural plasma cell infiltrates may be a histologic clue to the diagnosis of cutaneous plasmacytosis. Observations. Our patient had a five-year history of persistent reddish-brown plaques on the neck and trunk without systemic symptoms. Histologic examination showed dermal perivascular and perineural plasma cells with excess lambda light chain expression. Due to decreased quality of life caused by his skin lesions, he was placed on a chemotherapeutic regimen with bortezomib. Conclusions and Relevance. The patient was diagnosed with cutaneous plasmacytosis based on classic histopathology results with a recently characterized pattern of perineural involvement. Bortezomib therapy was initiated to manage his skin eruption, which has not been previously described as a treatment for this chronic condition.

    Cutaneous disease is the third most frequent manifestation of mucormycosis. The clinical manifestations of and subsequent mortality due to cutaneous mucormycosis are dependent on the mode of acquisition and the host immune status. Here, we describe the epidemiology, clinical presentation, microbiology, and outcomes of 16 cutaneous mucormycosis infections managed in an Australian tertiary hospital over a 15-year period. The proportion with localized (56%), deep (38%), and disseminated (6%) cutaneous disease as well as the overall mortality (25%) were consistent with findings reported in the published literature. Two novel forms of hospital-acquired infection were reported following a sacral pressure sore and insertion of a foreign body during a bone graft procedure. The majority of patients were immunocompetent (75%) and/or suffered trauma (56%) with associated environmental contamination. A novel finding was that motor vehicle accidents (MVAs) accounted for 78% of all trauma-related cases, suggesting MVAs should receive greater recognition as a potential precipitant of cutaneous mucormycosis. Aggressive decontamination and debridement of devitalized tissue following trauma is therefore likely to play an important role in the prevention of this rare but potentially devastating infection. © The Author 2014.

    Directory of Open Access Journals (Sweden)

    Margaret Taghavi

    2014-10-01

    Full Text Available Background: Primary cutaneous B-cell lymphoma typically localizes to the skin, and dissemination to internal organs is rare. Lymphomatous involvement of the breasts is also rare. We describe the clinical and radiological findings of an unusual case of primary cutaneous B-cell lymphoma presenting as an isolated breast mass without associated skin changes. Case Presentation: The patient was a 55-year-old Caucasian female who initially presented with cutaneous B-cell lymphoma around her eyes and forehead with recurrence involving the skin between her breasts. Three years after terminating treatment due to a lack of symptoms, she presented for an annual screening mammogram that found a new mass in her upper inner right breast without imaging signs of cutaneous extension. On physical examination, there were no corresponding skin findings. Due to the suspicious imaging features of the mass that caused concern for primary breast malignancy, she underwent a core biopsy which revealed cutaneous B-cell lymphoma. Conclusion: When evaluating patients with a systemic disease who present with findings atypical for that process, it is important to still consider the systemic disease as a potential etiology, particularly with lymphoma given its reputation as a great mimicker.

    Full Text Available Gonorrhea is one of the most common sexually transmitted diseases in the US with 700,000 annual cases. Although most cases of gonorrhea are localized, approximately 0.5–3% become disseminated. Here we discuss a rare case of a patient with systemic lupus erythematosus (SLE who developed septic shock from disseminated gonorrhea infection (DGI. Our patient is a 24-year-old woman with SLE, mixed connective tissue disease with cutaneous vasculitis, and lupus nephritis who presented with several weeks of malaise and generalized body aches associated with a diffuse rash along her fingers, palms, and trunk. Infectious workup was unrevealing with the exception of a positive gonorrhea test obtained from a cervical swab. Given her symptoms of tenosynovitis, the appearance of her skin lesions, and her positive gonorrhea test, she was diagnosed with septic shock secondary to DGI. With antibiotic treatment, the patient reported a dramatic improvement of the pain in her swollen joints and her rash receded. Patients diagnosed with SLE carry an increased risk of gonorrhea regardless of whether or not they are being treated for their SLE. Although it is well-documented that SLE is associated with severe DGI, few describe it resulting in overt septic shock.

  8. Knowledge dissemination: a core mission

    CERN Multimedia

    2011-01-01

    It’s been a year since the CERN Council approved our policy on intellectual property management, so I’d like to take a look at what we’ve achieved since then. In short, a great deal. We’ve moved away from a fairly unregulated approach towards a well balanced and clearly defined system built around sound intellectual property management designed to deliver maximum dissemination and benefit for society from CERN innovation. It’s a move that I celebrate and fully support.   In 2009, CERN signed two partnership agreements to develop CERN technologies, two commercial licenses and eleven R&D licenses. Last year, the figures were six partnership agreements, five commercial licenses and twenty R&D licenses, indicating a real increase in dissemination efforts. From 2009 to 2010, however, the number of new technologies that were identified and disclosed hardly changed: nine in 2009, ten in 2010. These numbers are good, but we must improve, particu...

    A 67-year-old female presented with a 20-year-old lesion involving the right ear and preauricular area mimicking tuberculous lupus. Fusarium oxysporum infection was confirmed by biopsy studies and cultures. The biopsy specimen showed an unusually extensive dermal invasion with fungal hyphae. This is an uncommon clinical presentation for Fusarium infection in a healthy patient. When referred to us, the patient had received antifungal therapy with itraconazole without any benefit. Improvement was obtained with fluconazole therapy. The spectrum of cutaneous involvement related to Fusarium spp. includes toxic reactions, colonization, superficial indolent infection, deep cutaneous or subcutaneous infections and disseminated infection.

  14. Specific cutaneous manifestations of internal malignancy.

    Kaplan, R P

    1986-01-01

    In summary, carcinoma is the most frequent cancer that metastasizes to the skin; lung cancer in men and breast cancer in women. Clinically distinctive patterns of cutaneous metastasis of epithelial origin include alopecia neoplastica, pulsatile nodules, Sister Mary Joseph's nodules, morpheaform, and cellulitis-like lesions. Biopsying these lesions reveals adenocarcinoma, squamous cell carcinoma, or anaplastic carcinoma. The type of histologic pattern seen can be a clue to the organ of origin giving rise to the cutaneous metastasis. Skin that is damaged allows for circulating malignant cells, often of epithelial or leukemic origin, to lodge and proliferate locally (inflammatory oncotaxis). The commonest form of leukemia to affect the skin of elderly males is chronic lymphocytic leukemia. However, when leukemia involves the mucous membranes, acute myeloid leukemia (acute monocytic and acute myelomonocytic leukemia) is the most likely diagnosis. When papules, nodules, or plaques develop on the head, neck, or torso in a middle-aged male accompanied by lymphadenopathy, there must be a high index of suspicion that these lesions are metastatic lymphomatous deposits. Definitive histologic diagnosis on a skin biopsy specimen is difficult. In this situation, it is best to rely on histologic patterns seen in lymphoid tissue along with cellular marker studies. An elderly patient having bone pain, anemia, elevated blood calcium level, and renal failure along with purplish or skin-colored nodules and plaques on the trunk has a good chance of having multiple myeloma. Biopsying these lesions is most certain to reveal atypical plasma cells, and blood immunoelectrophoresis will demonstrate characteristic monoclonal gammopathy. There are two malignancies seen in children under 3 years of age that often times affect the skin in a characteristic fashion. Letterer-Siwe disease, which is distinguished from other histocytic disorders by its cell of origin, the Langerhans cell, clinically

    Full Text Available Cutaneous cysticerci are often a pointer to the involvement of internal organs. A series of 33 patients including 5 vegetarians, between 10 to 48 years age, were investigated. Almost half the patients presented with cutaneous cysts of less than one month duration or were unaware of it. In the, other the duration varied upto 10 years. Cutaneous cysts were present in the case&Mental retardation, diminished vision and flashes of lights were, recorded in one case each, raised intracranial tension in 11 and seizures in 29 patients. Four, of the 6 patients with solitary cysts had no involvement of the internal- organs, whereas all the 27 patients with multiple had in nt of brain. Trunk was the commonest site in 16 patients. The other sites involved were scalp, eyelids, face, tongue neck, breast and limbs. Stool examination -for tapeworm segments/ eggs was positive in 2,calcification was seen on X-ray examination of skull in one and of soft tissues in 3, CT scan of skull was suggestive of cysticerci in 27 and skin biopsy for cysticercosis was confirmatory in all the 33 patients. Four patients with a solitary cutaneous cyst were treated by excision. One patients with neurocutaneous cysts was treated with albendazole without response. Out of 16patients with mucocutaneous and neurocutaneous cysticercosis treated with praziquantel, one did not respond. 7 responded partially and 8 had complete relief.

    The aim of this study is to present 2 rare cases of cutaneous metastases originated from adenocarcinoma of the gastro-esophageal junction, thus, underline the need for early diagnosis and possible treatment of suspicious skin lesions among patients with esophageal malignancy. Metastatic cancer to the skin originated from internal malignancies, mostly lung cancer, breast cancer, and colorectal cancer, constitute 0.5 to 9% of all metastatic cancers.5,8,15 Skin metastases, mainly from squamous cell carcinomas of the esophagus, are rarely reported. Cutaneous metastasis is a finding indicating progressiveness of the disease.17 More precisely, median survival is estimated approximately 4.7 months.2,14 This study is a retrospective review of 2 cases of patients with adenocarcinoma of the esophagus and a review of the literature. Two patients aged 60 and 32 years old, respectively, underwent esophagectomy. Both pathologic reports disclosed adenocarcinoma of the gastro-esophageal junction staged T3 N2 M0 (stage IIIB). During follow-up time, the 2 patients were diagnosed with cutaneous metastases originated from the primary esophageal tumor 11 and 4 months after surgery, respectively. The first patient is alive 37 months after diagnosis, while the second one died 16 months after surgery. Cutaneous metastasis caused by esophageal adenocarcinoma is possible. Therefore, follow-up of patients who were diagnosed with esophageal malignancy and underwent esophagectomy is mandatory in order to reveal early surgical stages. PMID:25785344

    Parasitic diseases result in a significant global health burden. While often thought to be isolated to returning travelers, parasitic diseases can also be acquired locally in the United States. Therefore, clinicians must be aware of the cutaneous manifestations of parasitic diseases to allow for prompt recognition, effective management, and subsequent mitigation of complications. This commentary also reviews pharmacologic treatment options for several common diseases.

    Full Text Available Patients with rheumatoid arthritis (RA have 2-fold increased risk of herpes zoster. In literature, limited information exists about disseminated cutaneous zoster in RA patients. An 83-year-old African-American female with RA presented with generalized and widespread vesicular rash covering her entire body. Comorbidities include hypertension, type II diabetes, and dyslipidemia. Patient was on methotrexate 12.5 mg and was not receiving any corticosteroids, anti-TNF therapy, or other biological agents. The patient was afebrile (98 F with no SIRS criteria. Multiple vesicular lesions were present covering patient’s entire body including face. Lesions were in different stages, some umbilicated with diameter of 2–7 cm. Many lesions have a rim of erythema with no discharge. On admission, patient was also pancytopenic with leukocyte count of 1.70 k/mm3. Biopsies of lesions were performed, which were positive for Varicella antigen. Subsequently, patient was started on Acyclovir. The patient’s clinical status improved and rash resolved. Our patient presented with “atypical” clinical picture of disseminated cutaneous zoster with no obvious dermatome involvement. Disseminated zoster is a potentially serious infection that can have an atypical presentation in patients with immunocompromised status. High index of suspicion is needed to make the diagnosis promptly and to initiate therapy to decrease mortality and morbidity.

    Full Text Available Ankylosing spondylitis is a chronic inflammatory disorder affecting mainly the axial skeleton. Here we report a case of a man with a clinical suspicion of ankylosing spondylitis but with a persistence of increased inflammatory markers. In this case, 18F-FDG-PET/CT revealed multiple hypermetabolic lesions in axial skeleton, lymph nodes, and the lung, suggestive of either disseminated tuberculosis or lymphoma. Histological analysis of the pulmonary lesion revealed mycobacterium tuberculosis. This case highlights, firstly, the importance of excluding other diagnoses in the presence of clinical picture of ankylosing spondylitis and high inflammatory markers and, secondly, the determining role of PET/CT.

We report 208 cases of patients with histoplasmosis and AIDS, describing the epidemiological, clinical, laboratory and therapeutic aspects. The in vitro antifungal susceptibility test was carried out by the microdilution method, according to Clinical and Laboratory Standards Institute, with H. capsulatum in the filamentous and yeast phases, against the antifungals amphotericin B, fluconazole, itraconazole, voriconazole and caspofungin. In 38.9% of the cases, histoplasmosis was the first indicator of AIDS and in 85.8% of the patients the CD4 cell count was lower than 100 cells/mm(3). The lactate dehydrogenase levels were high in all the patients evaluated, with impairment of hepatic and renal function and evolution to death in 42.3% of the cases. The in vitro susceptibility profile demonstrated there was no antifungal resistance among the isolates evaluated. There was a significant increase in the number of histoplasmosis cases in HIV-positive patients during the period surveyed in the state of Ceará, northeastern Brazil, but no antifungal resistance among the recovered isolates of H. capsulatum.

    Although discontinuation of suppressive antifungal therapy for acquired immunodeficiency syndrome (AIDS)-associated histoplasmosis is accepted for patients with immunologic recovery, there have been no published studies of this approach in clinical practice, and minimal characterization of individuals who relapse with this disease. We performed a multicenter retrospective cohort study to determine the outcome in AIDS patients following discontinuation of suppressive antifungal therapy for histoplasmosis. Ninety-seven patients were divided into a physician-discontinued suppressive therapy group (PD) (38 patients) and a physician-continued suppressive therapy group (PC) (59 patients). The 2 groups were not statistically different at baseline, but at discontinuation of therapy and at the most recent follow-up there were significant differences in adherence to therapy, human immunodeficiency virus (HIV) RNA, and urinary Histoplasma antigen concentration. There was no relapse or death attributed to histoplasmosis in the PD group compared with 36% relapse (p 150 cells/mL, HIV RNA <400 c/mL, Histoplasma antigenuria <2 ng/mL (equivalent to <4.0 units in second-generation method), and no CNS histoplasmosis.

    Classic histoplasmosis is a systemic endemic mycosis due to Histoplasma capsulatum var. capsulatum. A significant reduction in the morbidity and mortality of AIDS-related histoplasmosis has been observed since the introduction of highly active antiretroviral therapy (HAART) and secondary antifungal prophylaxis. The aim of this study was to determine the current state of prognosis and treatment response of HIV-positive patients with histoplasmosis in the Francisco J. Muñiz Infectious Diseases Hospital in Buenos Aires City. A retrospective study was conducted using the demographic, clinical, immunological and treatment data of 80 patients suffering from AIDS-related histoplasmosis. Of the 80 cases studied 65 were male, the median age was 36 years, with 73.7% of the patients being drug addicts, 82.5% of the patients was not receiving HAART at diagnosis, and 58.7% of the cases had less than 50 CD4+ cells/μl at the beginning of the treatment. The initial phase of treatment consisted of intravenous amphotericin B and/or oral itraconazole for 3 months, with 78.7% of the cases showing a good clinical response. Only 26/63 patients who were discharged from hospital continued with the follow-up of the HAART, secondary prophylaxis with itraconazole or amphotericin B. Secondary prophylaxis was stopped after more than one year of HAART if the patients were asymptomatic, had two CD4+ cell counts greater than 150cells/μl, and undetectable viral loads. No relapses were observed during a two-year follow up after prophylaxis was stopped. The treatment of histoplasmosis in HIV-positive patients was effective in 78.8% of the cases. The combination of HAART and secondary antifungal prophylaxis is safe, well tolerated, and effective. The low adherence of patients to HAART and the lack of laboratory kits for rapid histoplasmosis diagnosis should be addressed in the future.

    Human toxocariasis is a parasitic disease characterized by the presence of larvae of the genus Toxocara in human tissues. T canis and T cati, the adult roundworms of which are found in dog and cat intestines, respectively, are the most common causative agents of the disease. Toxocaral larvae usually cause two severe syndromes: visceral larva migrans and ocular larva migrans, depending on the location of the larvae. Two other syndromes, covert toxocariasis and common toxocariasis, which are less typical and not as severe, have also been described. During the last two decades, cutaneous manifestations such as chronic urticaria, chronic pruritus, and miscellaneous eczema, in patients with Toxocara antibodies, have been studied by different authors. In some cases, these cutaneous manifestations are the only signs indicating the presence of the disease, and they are cured after antihelmintic treatment when there is good patient compliance. In this review, we focus on these particular skin manifestations regarding their clinical description, diagnosis, and treatment.

    We present a case report of cutaneous myiasis in a foreign traveler who was infected by Dermatobia hominis while visiting South America. This patient developed a painful furuncular lesion on the anterior scalp and noted that the lesion drained a serosanguinous fluid for more than a month before definitive treatment. Invasion of mammalian tissue by the larval forms of D. hominis typically results in the formation of a classic furuncular lesion. For persons who present with a lesion that contains a central draining stoma located on an exposed body surface, the diagnosis of myiasis should always be considered. In addition to the case report, we present a discussion of furuncular myiasis and describe the peculiar life cycle of the human botfly. We also describe the various therapies that may be employed for treating cutaneous myiasis, including surgical extraction of the larva and asphyxiation of the larva by application of petroleum jelly or other fat derivatives to the central stoma or breathing aperture.

    Full Text Available Plexiform schwannoma is a rare neurogenic tumor, arising from skin and subcutaneous tissue. The presence of multiple schwannomas suggests a possible association with neurofibromatosis type 2 (NF2. A 50-year old male patient presented with multiple papulo-nodular cutaneous lesions on both arms and forearms. Histopathological examination revealed a dermal multinodular pattern of well-circumscribed masses of closely packed cells, with peripheral myxoid tissue, well-encapsulated in a thin collagenous capsule. S-100 immunohistochemical staining was diffusely and strongly positive. Neuron-specific enolase was positive, confirming a neural tissue tumor. An audiogram and Magnetic Resonance Imaging (MRI of cerebro-pontine angle showed no detected abnormality, excluding acoustic neuroma. Thus, we present a case of multiple bilateral isolated cutaneous plexiform schwannomas, not associated with NF2. Multiple plexiform schwannomas is a very rare entity, distinct from neurofibromatosis (NF, and being confined to the dermis is even more rarely reported.

    Full Text Available Carcinoma occurring in the cutaneous lesions of Lichen Planus though rarely mentioned in literature does occur and should be kept in mind while treating such lesions. We report a 16 year female who developed a squamous cell carcinoma in a long standing verrucous lichen planus in the lower leg. This case is being presented to indicate the possibility of malignant transformation of cutaneous lichen planus to carcinoma, especially in the hypertrophic forms and the need to have an early diagnosis so that it can be treated in the initial stages. A high degree of suspicion should be present whenever we come across a non healing lesion in a patient with lichen planus. A few markers, which may give us a clue for increased chances of malignant transformation in these cases is presented.

    There are several extrahepatic cutaneous manifestations associated with hepatitis B and hepatitis C virus infection. Serum sickness and polyarteritis nodosa are predominantly associated with hepatitis B infection, whereas mixed cryoglobulinemia associated vasculitis and porphyria cutanea tarda are more frequently seen in hepatitis C infection. The clinico-pathogenic associations of these skin conditions are not completely defined but appear to involve activation of the host immune system including the complement system. Management of the aforementioned cutaneous manifestations of viral hepatitis is often similar to that done in cases without viral hepatitis, with control of immune activation being a key strategy. In cases associated with hepatitis B and C, control of viral replication with specific antiviral therapy is also important and associated with improvement in most of the associated clinical manifestations.

    The pathophysiology of cutaneous lupus erythematosus (CLE) encompasses the complex interactions between genetics, the environment, and cells and their products. Recent data have provided enhanced understanding of these interactions and the mechanism by which they cause disease. A number of candidate genes have been identified which increase the risk of developing CLE. Ultraviolet radiation, the predominant environmental exposure associated with CLE, appears to initiate CLE lesion formation by...

    2012-01-01

    Cutaneous symptoms are observed in 25%-60% of polyarteritis nodosa (PN) patients. On the other hand, cutaneous polyarteritis nodosa (CPN) is designated for the cutaneous limited form of PN and demonstrates benign prognosis. However, there has been much debate on whether or not CPN can progress to PN. Although CPN lesions are fundamentally limited to skin, some CPN cases show extracutaneous symptoms such as peripheral neuropathy and myalgia. According to PN diagnostic criteria, a disease with both cutaneous and at least one extracutaneous symptom with appropriate histopathological findings can be diagnosed as PN. The same is true according to diagnostic criteria established by American College of Rheumatology (ACR). In addition, there are no specific diagnostic criteria for CPN. In this study, CPN cases were retrospectively collected from multiple Japanese clinics, and analyzed for detailed clinical and histopathological manifestations, in order to redefine the clinical entity of CPN and to propose appropriate diagnostic criteria for CPN and PN. According to the CPN description in Rook's Textbook of Dermatology, one of global standard textbooks, we collected 22 cases with appropriate histopathological findings. Of the 22 cases, none progressed to PN or death during the follow-up period, 32% had peripheral neuropathy, and 27% had myalgia. Regarding extracutaneous symptoms with CPN, 17 dermatological specialists in vasculitis sustained the opinion that CPN can be accompanied by peripheral neuropathy and myalgia, but these symptoms are limited to the same area as skin lesions. Based on these results, we devised new drafts for CPN and PN diagnostic criteria. Our study shows the efficacy of these criteria, and most dermatologists recognized that our new diagnostic criteria for CPN and PN are appropriate at the present time. In conclusion, this study suggests that CPN does not progress to PN, and introduces new drafts for CPN and PN diagnostic criteria. (*English

    Many new drugs are entering the marketplace and although some cutaneous reactions might be noted in the preclinical evaluation, some of the reactions, particularly those that are rare, will not be noted until the drugs enter widespread use. In addition, distinctive reactions may occur, as is the case with epidermal growth factor-receptor inhibitors. Careful observation and evaluation might result in a better understanding of "naturally" occurring skin disease.

    Full Text Available Introduction. Multiple myeloma is a hemathological malignancy characterized by the clonal proliferation of plasma cells in the bone the marrow. Extramedullary dissemination of multiple myeloma is uncommon. In several cases only, the multiple myeloma malignant plasma cells had diseminated to the lung parenchyma. Case report. We presented a case of multiple myeloma with lung plasmacytoma, in a 79-year-old patient, hospitalized for febrility and infiltrative mass in the right lung. Two months before the patient was admitted, because of developing terminal renal failure, hemodialysis treatment had started three times a week. Since then, the patient was oliguric, but because of febrility and hemoptysis that appeared, at first he was treated with dual antibiotic therapy which resulted in temporary improvement of his general condition, but pleural effusion remained. After thoracocentesis, followed by myelogram, the multiple myeloma diagnosis was established. Conclusion. In patients of middle and older age, with general weakness, exhaustion, loss of weight, renal failure which progresses to the end stage rapidly, if symptoms of respiratory tract occur, consider this uncommon disease - extramedullary dissemination of multiple myeloma.

  16. Small Bowel Dissemination of Coccidioidomycosis

    2015-01-01

    Full Text Available Gastrointestinal coccidioidomycosis is extremely rare, with less than 10 cases reported in the literature. We report a case of small bowel dissemination of coccidioidomycosis in a 21-year-old African American male with a history of living in San Joaquin Valley. The patient presented with one week of abdominal pain, nausea, shortness of breath, intermittent fever, and sweat, and one month of abdominal distention. A chest radiograph revealed complete effusion of left lung. A computed tomography scan of the abdomen showed diffuse small bowel thickening and enhancement, as well as omental and peritoneal nodules, and ascites. The coccidioidal complement fixation titer was 1 : 256. The duodenal biopsy revealed many spherules filled with round fungal endospores. Later, blood fungal culture showed positivity for Coccidioides immitis. The final diagnosis is disseminated coccidioidomycosis involving lungs, blood, and duodenum. Despite aggressive antifungal therapy, the patient’s clinical situation deteriorated and he succumbed to multisystem organ failure one and half months later. A high index of suspicion for gastrointestinal coccidioidomycosis should be maintained in patients from an endemic area presenting as abdominal distention and pain.

    Systemic lupus erythematosus (SLE) is the prototypic autoimmune condition, often affecting multiple organ systems, including the skin. Cutaneous lupus erythematosus (CLE) is distinct from SLE and may be skin limited or associated with systemic disease. Histopathologically, the hallmark of lupus-specific manifestations of SLE and CLE is an interface dermatitis. The cause of SLE and CLE is likely multifactorial and may include shared genetic factors. In this review, we will discuss the genetic findings related to the cutaneous manifestations of SLE and isolated CLE, with a particular focus on the lupus-specific CLE subtypes. Several major histocompatibility complex and nonmajor histocompatibility complex genetic polymorphisms have been identified which may contribute to the cutaneous manifestations of SLE and to CLE. Most of these genetic variants are associated with mechanisms attributed to the pathogenesis of SLE, including pathways involved in interferon and vitamin D regulation and ultraviolet light exposure. Although there is overlap between the genetic factors associated with SLE and CLE, there appear to be unique genetic factors specific for CLE. Improved understanding of the genetics of CLE may lead to the creation of targeted therapies, improving outcomes for patients with this challenging dermatologic condition.

    Chromatophoromas are neoplasms arising from pigment-bearing cells (chromatophores) of the dermis. While isolated cases have been reported in the literature, the prevalence and biological behavior of chromatophoromas in snakes are unknown. Forty-two chromatophoromas were identified among 4663 submissions (0.9%) to a private diagnostic laboratory in a 16-year period. The most commonly affected snakes were colubrids (23 cases, 55%) and vipers (8 cases, 19%). The San Francisco garter snake was the most commonly affected species (6 cases; 14% of all affected snake species and 3.7% of all garter snake submissions). No sex predilection was found. The age of 28 snakes ranged from 5 to 27 years. Single cutaneous chromatophoromas were most commonly observed and presented as pigmented cutaneous masses or plaques along any body segment. Euthanasia or death due to progressive neoplastic disease or metastasis was reported in 8 (19%) and 4 (10%) cases, respectively. The survival time of 4 animals ranged from 4 to 36 months. Microscopically, xanthophoromas, iridophoromas, melanocytic neoplasms, and mixed chromatophoromas were identified, with melanocytic neoplasms being most common. Microscopic examination alone was generally sufficient for the diagnosis of chromatophoroma, but immunohistochemistry for S-100 and PNL-2 may be helpful for diagnosing poorly pigmented cases. Moderate to marked nuclear atypia appears to be consistently present in cutaneous chromatophoromas with a high risk of metastasis, while mitotic count, lymphatic invasion, the level of infiltration, and the degree of pigmentation or ulceration were not reliable predictors of metastasis.

    Full Text Available Background: Many malignancies affecting the internal organs display cutaneous manifestations which may be either specific (tumor metastases or nonspecific lesions. Aims: The study is aimed at determining the frequency and significance of cutaneous manifestations among patients with internal malignancy. Materials and Methods: 750 cases of proven internal malignancy, who attended a cancer chemotherapy center in South India, were studied. Specific infiltrates were confirmed by histopathology, fine needle aspiration cytology (FNAC and marker studies. Results: Out of the 750 patients with internal malignancy, skin changes were seen in a total of 52 (6.93% patients. Conclusion: Cutaneous metastases (specific lesions were seen in 20 patients (2.66%: contiguous in 6 (0.8%, and non-contiguous in 14 (1.86%. Nonspecific skin changes were seen in 32 patients (4.26%. None of our patients presented with more than one type of skin lesions. Herpes zoster was the most common nonspecific lesion noticed in our patients, followed by generalized pruritus, multiple eruptive seborrheic keratoses, bullous disorder, erythroderma, flushing, purpura, pyoderma gangrenosum, insect bite allergy and lichenoid dermatitis.

    2016-06-01

    Full Text Available Carcinoma of the ampulla of Vater is a rare gastrointestinal tumor. Additionally, cutaneous metastasis from such an internal malignancy is also uncommon. We reported the case of a 55-year-old man afflicted with ampullary carcinoma with cutaneous metastasis. The patient did not undergo the standard Whipple procedure but received chemotherapy due to apparent left neck lymph node metastasis noted by initial PET/CT imaging. The skin metastasis presented as a left neck infiltrating purpuric lesion, which was confirmed by skin biopsy approximately one year after the patient's disease was first diagnosed. Thereafter, the patient received further chemotherapy pursuant to his course of medical management. Skin metastasis usually represents a poor patient prognosis. In these cases, treatment of cutaneous metastasis typically includes systemic chemotherapy and local management such as radiation therapy or tumor excision. And when choosing a chemotherapy regimen for the ampullary cancer, the histological subtypes (intestinal or pancreatobiliary should be comprehensively considered. In our review of the literature, the intestinal type seems to have less distant lymph node metastasis, advanced local invasion, as well as recurrence than pancreatobiliary type of ampullary cancer.

    The TNFalpha antagonists, including adalimumab, etanercept and infliximab, represent a class of anti-inflammatory and immunosuppressive drugs. Although cutaneous adverse effects are uncommon, they are varied. There is no particular risk profile to develop cutaneous adverse effects. The principal acute side effects are injection site reactions and pruritus. The major long term cutaneous side effects are infectious and inflammatory conditions. Neoplastic skin diseases are exceptional. The association with other immunosuppressive agents can increase the risk of developing cutaneous adverse effects. Some adverse effects, such as lupus erythematosus, require immediate withdrawal of the biological treatment, while in other cases temporary withdrawal is sufficient. The majority of the other cutaneous adverse effects can be dealt without interrupting biologic treatment. Preclinical and clinical investigations revealed that the new biologics, aiming IL12/23, IL23 and IL17, present a similar profile of cutaneous adverse effects, although inflammatory skin reactions may be less often encountered compared to TNFalpha antagonists.

  2. The Leukotriene B4/BLT1 Axis Is a Key Determinant in Susceptibility and Resistance to Histoplasmosis

    The bioactive lipid mediator leukotriene B4 (LTB4) greatly enhances phagocyte antimicrobial functions against a myriad of pathogens. In murine histoplasmosis, inhibition of the LT-generating enzyme 5-lypoxigenase (5-LO) increases the susceptibility of the host to infection. In this study, we investigated whether murine resistance or susceptibility to Histoplasma capsulatum infection is associated with leukotriene production and an enhancement of in vivo and/or in vitro antimicrobial effector function. We show that susceptible C57BL/6 mice exhibit a higher fungal burden in the lung and spleen, increased mortality, lower expression levels of 5-LO and leukotriene B4 receptor 1 (BLT1) and decreased LTB4 production compared to the resistant 129/Sv mice. Moreover, we demonstrate that endogenous and exogenous LTs are required for the optimal phagocytosis of H. capsulatum by macrophages from both murine strains, although C57BL/6 macrophages are more sensitive to the effects of LTB4 than 129/Sv macrophages. Therefore, our results provide novel evidence that LTB4 production and BLT1 signaling are required for a histoplasmosis-resistant phenotype. PMID:24465479

El caso índice consultó por sintomatología respiratoria grave, de comienzo súbito, que requirió hospitalización. En los otros casos, la infección cursó de manera asintomática pero se puso en evidencia por la reactividad en las pruebas serológicas con histoplasmina. La búsqueda de una fuente común de contagio llevó a sospechar que era la tierra de un vivero que se había utilizado como fertilizante de las plantas caseras. Las suspensiones de las tierras de las macetas sirvieron para inocular ratones BALB/c, de cuyos órganos fue posible aislar el agente etiológico, Histoplasma capsulatum var. capsulatum. Si bien la histoplasmosis es más frecuente en ciertas ocupaciones y es propia de áreas rurales, las epidemias y los brotes son ahora comunes en áreas urbanas debido a actividades como la urbanización masiva, la tala de árboles, las demoliciones y el uso de tierras enriquecidas con abonos orgánicos (gallinaza, guano.

    Full Text Available There are limited data about the cutaneous metastases of gynecological malignancies in the literature. Based on this limited number of studies, cutaneous metastases from gynecological malignancies are uncommon occurrences. Cutaneous metastases from the synchronous endometrioid carcinoma of the uterine corpus and bilateral ovaries arising from endometriosis are extremely rare. Herein, we report a 51-year-old woman with FIGO Stage 1A Grade 1 endometrial endometrioid-type adenocarcinoma and synchronous bilateral Stage 1B ovarian endometrioid-type adenocarcinoma who presented 34 months following total abdominal hysterectomy and bilateral salpingo-oophorectomy with skin metastases. After the patient underwent an excisional biopsy, we applied a palliative radiotherapy. The patient received the combination therapy with cisplatin and doxorubicin after the completion of radiotherapy but the disease evolution was rapidly fatal and the patient died 4 months after her admission to our department due to widely disseminated disease.

Unfortunately, the possibilities for treating flagellated kinetoplastid infections are still very limited and most of the available drugs exhibit severe side effects. Although the development of new drugs for Leishmania has markedly improved in the last years, the tendency is still to employ antimonial compounds. On the other hand, treatment for Chagas’ disease is only available for the acute phase with no effective therapeutical options for chronic stage disease. The following case report substantiates the recently discovered effect of amiodarone as a nonconventional antiparasitic drug, particularly against Leishmania, breaching a new perspective in the therapeutic management of these important infectious parasitic diseases.Keywords: Chagas’ disease, leishmaniasis, chemotherapy, amiodarone

    Dermatomyositis (DM) is a systemic inflammatory condition characterized by cutaneous and muscle findings, in addition to potential involvement of other organ systems. A distinct subtype of DM exists that is categorized by cutaneous findings with absent or minimal muscle involvement, referred to as clinically amyopathic dermatomyositis or dermatomyositis sine myositis. A variety of topical, immunosuppressive, and immunomodulatory therapies have been utilized to treat cutaneous DM. The advent of biological agents including tumor necrosis factor-α antagonists, intravenous immunoglobulin, rituximab, and others has allowed for the use of these agents with varying degrees of success for the treatment of cutaneous DM.

    Adenosine deaminase (ADA) activity has been discovered in several inflammatory conditions; however, there are no data associated with cutaneous anthrax. The aim of this study was to investigate serum ADA activity in patients with cutaneous anthrax. Sixteen patients with cutaneous anthrax and 17 healthy controls were enrolled. We measured ADA activity; peripheral blood leukocyte, lymphocyte, neutrophil, and monocyte counts; erythrocyte sedimentation rate; and C reactive protein levels. Serum ADA activity was significantly higher in patients with cutaneous anthrax than in the controls (panthrax.

    Full Text Available Cutaneous metastases from primary internal malignancies are an uncommon presentation. Cutaneous metastases are more frequently seen in breast cancer than in any other visceral malignancy in women. Medical practitioners should be vigilant of the possibility of unusual presentations of metastatic disease in breast cancer patients with lobular carcinoma presenting as cutaneous lesions mimicking benign dermatological conditions. Herein, we present a case of a 75-year-old woman presenting with cutaneous lobular breast carcinoma metastases on her anterior right leg, which had previously been misdiagnosed as dermatitis for 9 years.

    Full Text Available Paracoccidioidomycosis (PCM is a deep mycosis with primary lung manifestations that may present cutaneous and oral lesions. Oral lesions mimic other infectious diseases or even squamous cell carcinoma, clinically and microscopically. Sometimes, the dentist is the first to detect the disease, because lung lesions are asymptomatic, or even misdiagnosed. An unusual case of PCM with 5 months of evolution presenting pulmonary, oral, and cutaneous lesions that was diagnosed by the dentist based on oral lesions is presented and discussed.

  12. Obstetrical disseminated intravascular coagulation score.

    2014-06-01

    Obstetrical disseminated intravascular coagulation (DIC) is usually a very acute, serious complication of pregnancy. The obstetrical DIC score helps with making a prompt diagnosis and starting treatment early. This DIC score, in which higher scores are given for clinical parameters rather than for laboratory parameters, has three components: (i) the underlying diseases; (ii) the clinical symptoms; and (iii) the laboratory findings (coagulation tests). It is justifiably appropriate to initiate therapy for DIC when the obstetrical DIC score reaches 8 points or more before obtaining the results of coagulation tests. Improvement of blood coagulation tests and clinical symptoms are essential to the efficacy evaluation for treatment after a diagnosis of obstetrical DIC. Therefore, the efficacy evaluation criteria for obstetrical DIC are also defined to enable follow-up of the clinical efficacy of DIC therapy.

  13. Treatment of Disseminated Intravascular Coagulation.

    2015-11-01

    Disseminated intravascular coagulation (DIC) is a syndrome characterized by systemic activation of blood coagulation, generation of thrombin, and leading to disturbance of the microvasculature. In this article, definition and diagnostic criteria of DIC depend on the International Society of Thrombosis and Haemostasis (ISTH). There is no gold standard for diagnosis of DIC, only low quality evidence is used in general practice. Many diagnostic tests and repeated measurement are required. For the treatment of DIC, there is no good quality evidence. The most important treatment for DIC is the specific treatment of the conditions associated DIC. Platelets and/or plasma transfusion may be also necessary if indicated. Nevertheless, there is no gold standard for diagnosis and treatment of DIC, we use only low quality evidence in general practice.

  14. Apropos of a case of cutaneous metastasis from laryngeal cancer with review of literature

    2015-01-01

    Full Text Available Cutaneous metastasis from laryngeal carcinoma is a rare occurrence. A 55-year-old male patient with supraglottic cancer was treated with concurrent chemoradiation. Eighteen months later, he presented with ulceroproliferative growth on dorsum of the right hand. Biopsy revealed metastatic squamous cell carcinoma. Further investigations revealed underlying bone destruction with lung metastasis. In view of poor general condition and widespread dissemination of disease, palliative radiotherapy was delivered to the hand of the patient. He achieved satisfactory palliation in form of pain relief, control of bleeding, and discharge. The present report serves to emphasize the importance of properly diagnosing metastatic spread to unusual sites. Such metastasis is rare and is associated with a poor prognosis. Treatment is usually aimed at providing pain relief in these patients with limited life expectancy. Hence, we present a case of extensive cutaneous metastasis from laryngeal carcinoma with review of the literature.

    Wolf's isotopic response designates the appearance of two subsequent unrelated dermatoses in the same anatomic location. We report the case of a 51-year-old man with a medical history of chronic lymphocytic leukemia without known extra-hematopoietic involvement. The patient developed a disseminated papulo-vesiculous eruption, diagnosed as varicella. Few days after recovering, an erythematous and violaceous papular dermatosis with histopathological examination compatible with leukemic infiltration appeared on the scars of previous herpetic lesions. Complete remission was obtained under systemic corticotherapy, without cutaneous recurrence or blastic transformation. Wolf's isotopic response is attributed to a localized immunologic imbalance following a certain stimulus. In this patient, herpetic infection acted as a local spur for inaugural cutaneous leukemic infiltration, with no impact on the prognosis for the underlying disease.

    2002-01-01

    Full Text Available Although cases of leishmaniasis co-infection have been described in acquired immunodeficiency syndrome patients as well as those who have undergone organ transplants, to our knowledge, the present report is the first documented case of simultaneous cutaneous, visceral and ocular leishmaniasis due to Leishmania (Viannia braziliensis in a transplant patient. The patient had been using immunosuppressive drugs since receiving a transplanted kidney. The first clinical signs of leishmaniasis included fever, thoracic pain, hepatosplenomegaly, leucopenia and anemia. The cutaneous disease was revealed by the presence of amastigotes in the skin biopsy. After three months, the patient presented fever with conjunctive hyperemia, intense ocular pain and low visual acuity. Parasites isolated from iliac crest, aqueous humor and vitreous body were examined using a range of molecular techniques. The same strain of L. (V. braziliensis was responsible for the different clinical manifestations. The immunosuppressive drugs probably contributed to the dissemination of Leishmania.

    Cutaneous tuberculosis (CT) is rare in industrialized countries. Given the clinicopathological polymorphism and the difficulty of isolating the pathogen, diagnosis can be difficult. The condition may be associated with other known locations of the disease or in rare cases, it may be a tell-tale sign, as in our case, in which leg ulcers revealed paucisymptomatic disseminated tuberculosis. A 67-year-old man was referred for rapidly extensive ulcers of the right leg contiguous to debilitating arthritis of the knee of unknown aetiology for 18 months. Earlier investigations revealed thymoma and a pulmonary nodule considered to be sarcoidosis. A skin biopsy showed a granulomatous eosinophilic-rich infiltrate and vasculitis of the small vessels. Screening of the skin sample and gastric aspirate for Koch Bacillus (BK) was negative. A diagnosis of sarcoidosis was made. A positive QuantiFERON test eventually led to the correct diagnosis. On further testing of bronchoalveolar fluid and a synovial biopsy, culture for Mycobacterium tuberculosis (MT) was positive. The PET scan showed high metabolism in the prostate, bone, spleen, liver, nodes and heart. The quad- and then dual-antibiotic antitubercular therapies produced a rapid improvement but treatment was continued over 12 months, given the persistence of high metabolism on PET-CT scan and the low blood rifampicin concentration. A CT should be considered in the presence of giant-cell granulomas, even in the absence of caseous necrosis, and where both direct examination and culture for the skin are negative. Our case also underlines the importance of an extensive workup to rule out disseminated disease even if the patient is not symptomatic. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Full Text Available Background: Cutaneous leishmaniasis (CL is known for its clinical diversity and increasing numbers of new and rare variants of the disease are being reported these days. Aim: The aim of this descriptive study was to look for and report the atypical presentations of this common disease occurring in Pakistan. Methods: The study was carried out in three hospitals (MH, Rawalpindi; PAF Hospital, Sargodha; and CMH, Muzaffarabad from 2002 to 2006. Military and civilian patients of all ages, both males and females, belonging to central and north Punjab province and Kashmir were included in the study. Clinical as well as parasitological features of cutaneous leishmaniasis were studied. The unusual lesions were photographed and categorized accordingly using simple descriptive statistics. Results: Out of 718 patients of cutaneous leishmaniasis, 41 (5.7% had unusual presentations. The commonest among unusual morphologies was lupoid leishmaniasis 14 (34.1%, followed by sporotrichoid 5 (12.1%, paronychial 3 (7.3%, lid leishmaniasis 2 (4.9%, psoriasiform 2 (4.9%, mycetoma-like 2 (4.9%, erysipeloid 2 (4.9%, chancriform 2 (4.9%, whitlow 1 (2.4%, scar leishmaniasis 1 (2.4%, DLE-like 1 (2.4%, ′squamous cell carcinoma′-like 1 (2.4%, zosteriform 1 (2.4%, eczematous 1 (2.4%, verrucous 1 (2.4%, palmar/plantar 1 (2.4% and mucocutaneous 1 (2.4%. Conclusion: In Pakistan, an endemic country for CL, the possibility of CL should be kept in mind while diagnosing common dermatological diseases like erysipelas, chronic eczema, herpes zoster, paronychia; and uncommon disorders like lupus vulgaris, squamous cell carcinoma, sporotrichosis, mycetoma and other deep mycoses.

  20. Targeted therapies for cutaneous melanoma.

    Kee, Damien; McArthur, Grant

    2014-06-01

    Melanoma is resistant to cytotoxic therapy, and treatment options for advanced disease have been limited historically. However, improved understanding of melanoma driver mutations, particularly those involving the mitogen-activated protein kinase pathway, has led to the development of targeted therapies that are effective in this previously treatment-refractory disease. In cutaneous melanomas with BRAF V600 mutations the selective RAF inhibitors, vemurafenib and dabrafenib, and the MEK inhibitor, trametinib, have demonstrated survival benefits. Early signals of efficacy have also been demonstrated with MEK inhibitors in melanomas with NRAS mutations, and KIT inhibitors offer promise in melanomas driven through activation of their target receptor.

    Swain, Digendranath; Gupta, Anurag

    2016-11-07

    A cutaneous wound may rupture during healing as a result of stretching in the skin and incompatibility at the wound-skin interface, among other factors. By treating both wound and skin as hyperelastic membranes, and using a biomechanical framework of interfacial growth, we study rupturing as a problem of cavitation in nonlinear elastic materials. We obtain analytical solutions for deformation and residual stress field in the skin-wound configuration while emphasizing the coupling between wound rupture and wrinkling in the skin. The solutions are analyzed in detail for variations in stretching environment, healing condition, and membrane stiffness.

    Background. In the primary infection of pulmonary histoplasmosis, pulmonary lesions are commonly solitary and associated with hilar and/or mediastinal nodal diseases, which spontaneously resolve, resulting in calcifications in individuals with normal cellular immunity. Purpose. To assess the lymphatic drainage to the mediastinum from each pulmonary segment and lobe using computed tomographic (CT) observations of a calcified primary complex pulmonary histoplasmosis and predict which patients with N2 disease that would benefit from surgery. Material and Methods. We collected 585 CT studies of patients with primary complex histoplasmosis consisting of solitary calcified pulmonary lesions and calcified hilar and/or mediastinal nodal disease. Using the N stage criteria of non-small cell lung cancer, we assessed the distribution of the involved hilar and mediastinal nodes depending on the pulmonary segment of the lesion, with a focus on skip involvement. We also assessed the correlation between the incidence of N1and skip N2 involvement and the mean number of involved mediastinal nodal stations in the non-skip N2 and skip N2 groups. Results. Skip involvement was common in the apical segment (9/45, 20.0%), posterior segment (7/31, 22.6%), and mediolbasal segment (13/20, 65.0%) in the right lung, and in the apicoposterior segment (7/55, 12.7%), lateral basal segment (6/26, 23.1%), and posterobasal segment (16/47, 34.0%) in the left lung. The incidence of skip involvement in each segment showed a significant inverse correlation with that of N1 involvement (r = -0.51, P <0.05) in both lungs. The mean number of involved mediastinal nodal stations in the non-skip N2 and skip N2 groups in all segments of both lungs were 1.4 (434/301) and 1.2 (93/77), and the former was significantly greater than the latter (P <0.01). Conclusion. Our data showed a predictable pattern of segmental and lobar lymphatic drainage to the mediastinum and suggested that skip involvement could represent

    Full Text Available Os autores relatam uma microepidemia de histoplasmose pulmonar, com cinco crianças que desenvolveram a doença em um período de 7 a 14 dias após a limpeza de um forno desativado para produção de carvão vegetal. Todas apresentaram quadro de febre alta persistente, tosse seca, astenia e anorexia, com 28 dias de evolução. Quando buscaram atendimento médico, uma delas encontrava-se taquipnéica, febril, com hepatomegalia e palidez cutânea, estando as restantes em regular estado geral e já sem febre. As radiografias de tórax demonstravam, em todos os casos, infiltrados reticulonodulares grosseiros, difusos e bilaterais, além de linfonodomegalias hilares. As tomografias computadorizadas evidenciaram pequenos nódulos difusos, com distribuição aleatória, além das linfonodomegalias. Os diagnósticos foram confirmados por meio da imunodifusão em gel para Histoplasma capsulatum, que foi positiva em todas as amostras pareadas coletadas com 15 dias de intervalo. Apenas uma criança necessitou de internação, por causa de importante queda no estado geral, sendo realizado tratamento de suporte e observação. Todas as crianças evoluíram com melhora clínica, sem o uso de antifúngicos, e foram submetidas a tomografias de controle após cerca de 50 dias, que demonstraram importante regressão das lesões.The authors report a pulmonary histoplasmosis outbreak occurring in five children after the cleaning of a deactivated coal furnace. The symptoms were high fever, dry cough, asthenia and anorexia. By the time parents seeked for medical care, only one child remained symptomatic with fever, tachypnea and hepatomegaly. All the patients had similar radiological findings. Chest films showed diffuse, bilateral, reticulonodular infiltrates and lymph node enlargement. Computed tomography showed small nodules with a random distribution and hilar and mediastinal lymph nodes. Diagnosis was confirmed by positive gel immunodiffusion for Histoplasma

    2014-01-01

    Cutaneous malignant melanoma (CMM) has a high risk of dissemination to regional lymph nodes and visceral organs. Recurrences are most frequently seen within the first 2-3 years after initial treatment, but these patients have a life-long risk of relapse. The prognosis is highly dependent on lymph...... node involvement and distant metastases, accentuating the importance of close surveillance to identify disease progression at an early stage, and thereby detect recurrences amenable to treatment. Positron emission tomography (PET) has already been proven useful in the staging of CMM, but the utility...

    Gallium imaging is increasingly being used for the early detection of complications in patients with AIDS. A 26-year-old homosexual man who was HIV antibody positive underwent gallium imaging for investigation of possible Pneumocystis carinii pneumonia. Widespread cutaneous focal uptake was seen, which was subsequently shown to be due to mycobacterium avium-intracellulare (MAI) septicemia. This case demonstrates the importance of whole body imaging rather than imaging target areas only, the utility of gallium imaging in aiding the early detection of clinically unsuspected disease, and shows a new pattern of gallium uptake in disseminated MAI infection.

    Abstract Aim: To provide an overview of the medical literature on cutaneous fistulization in patients with hydatid disease (HD). Methods: According to PRISMA guidelines a literature search was made in PubMed, Medline, Google Scholar, and Google databases were searched using keywords to identify articles related to cutaneous fistulization of the HD. Keywords used were hydatid disease, hydatid cyst, cutaneous fistulization, cysto-cutaneous fistulization, external rupture, and external fistulization. The literature search included case reports, review articles, original articles, and meeting presentations published until July 2016 without restrictions on language, journal, or country. Articles and abstracts containing adequate information, such as age, sex, cyst size, cyst location, clinical presentation, fistula opening location, and management, were included in the study, whereas articles with insufficient clinical and demographic data were excluded. We also present a new case of cysto-cutaneous fistulization of a liver hydatid cyst. Results: The literature review included 38 articles (32 full text, 2 abstracts, and 4 unavailable) on cutaneous fistulization in patients with HD. Among the 38 articles included in the study, 22 were written in English, 13 in French, 1 in German, 1 in Italian, and 1 in Spanish. Forty patients (21 males and 19 females; mean age ± standard deviation, 54.0 ± 21.5 years; range, 7–93 years) were involved in the study. Twenty-four patients had cysto-cutaneous fistulization (Echinococcus granulosus); 10 had cutaneous fistulization (E multilocularis), 3 had cysto-cutaneo-bronchio-biliary fistulization, 2 had cysto-cutaneo-bronchial fistulization; and 1 had cutaneo-bronchial fistulization (E multilocularis). Twenty-nine patients were diagnosed with E granulosis and 11 had E multilocularis detected by clinical, radiological, and/or histopathological examinations. Conclusion: Cutaneous fistulization is a rare complication of HD

    Idiopathic immune myopathies (IIM) are an heterogeneous group of autoimmune muscle disorders characterized by progressive muscle involvement. Dermatomyositis (DM) is the most common form of IIM. It is a multisystem disorder characterized by symmetric proximal, extensor, inflammatory myopathy, vascular involvement and a characteristic cutaneous eruption. Six types of DM have been identified: idiopathic, juvenile (JDM), cancer-related other autoimmune diseases-related, iatrogenic DM and amyopathic DM. Cutaneous manifestations of DM are the most important aspect of this disease and can precede from several months to years muscle or systemic involvement. Three groups of signs have been described: pathognomonic, highly characteristic and compatible. Although differences exist among the different clinical presentation of skin lesions, they share common histological findings including the presence of interface dermatitis with epidermal atrophy, basement membrane degeneration, vacuolar alteration of basal keratinocytes, and dermal changes consisting of interstitial mucin deposition and a sparse lymphocytic infiltrate. DM is a serious disease; the correct evaluation of any skin lesion suggesting an early diagnosis is of utmost importance. Skin signs may, also, represent a marker of treatment efficacy even though systemic symptoms worsening may not always be followed by more severe skin lesions.

    Cutaneous vasculitides (CV) can be idiopathic or secondary to several triggers, including drugs, which account for up to 30% of all the cases of CV. Several drugs can induce CV, including some medications commonly used in dermatology, including minocycline, and several new drugs, such as anti-TNF agents. Different pathomecanisms are involved in the development of drug-induced CV, including the formation and deposition of immune complexes, the induction of neutrophil apoptosis, the formation of neoantigens between the drugs and proteins from the host, the shift of the immune response, and others. Although the diagnosis is difficult, because the clinical picture of drug-induced CV is in general indistinguishable from that of other forms of CV, it is important to recognize such entities in order to correctly manage the patient. Anamnesis, diagnostic algorithms to assess the likelihood of the association between a drug and a cutaneous reaction, skin biopsy and laboratory testing (including the search for antineutrophil cytoplasmic antibodies) are useful tools to make a diagnosis of drug-induced CV. About the therapy, while in idiopathic vasculitides the treatment is usually more aggressive and long-lasting, very often requiring a maintenance therapy with immunosuppressive drugs, in drug-induced CV the discontinuation of the suspected drug alone is usually enough to achieve complete remission, making the prognosis usually very good.

    Full Text Available Introduction. Bronchial carcinoids belong to a rare type of lung tumors. If they do not expose outstanding neuroendocrine activity, they develop without clearly visible symptoms. They are often detected during a routine examination. According to their clinical pathological features, they are divided into typical and atypical tumors. Typical bronchial carcinoids metastasize to distant organs very rarely. Localized forms are effectively treated by surgery. The methods of conservative treatment should be applied in other cases. Case report. We presented a 65-year-old patient with carcinoid lung tumor detected by a routine examination. Additional analysis (chest X-ray, computed tomography of the chest, ultrasound of the abdomen, skeletal scintigraphy, bronhoscopy, histopathological analysis of the bioptate of bronchial tumor, as well as bronchial brushing cytology and immunohistochemical staining performed with markers specific for neuroendocrine tumor proved a morphologically typical lung carcinoid with dissemination to the liver and skeletal system, which is very rarely found in typical carcinoids. Conclusion. The presented case with carcinoid used to be showed morphological and pathohistological characteristics of typical bronchial carcinoid. With its metastasis to the liver and skeletal system it demonstrated unusual clinical course that used to be considered as rare phenomenon. Due to its frequent asymptomatic course and varied manifestation, bronchial carcinoid could be considered as a diagnostic challenge requiring a multidisciplinary approach.

    2016-01-01

    Full Text Available Hemophagocytic lymphohistiocytosis (HLH is an aggressive and life-threating immune dysregulation syndrome characterized by persistent activation of the mononuclear phagocytic system leading to uncontrolled systemic hyperinflammatory response. The proliferation and activation of histiocytes and lymphocytes lead to production of large amounts of cytokines, also called cytokine storm. Hematopoietic and lymphoid tissues are directly involved while other organs are damaged by circulating cytokines. Primary HLH is attributed to genetic defects of the immune system and secondary HLH is usually seen in adults secondary to malignancy, infection, or autoimmune diseases. Zoonotic diseases including fungal infections are an important cause of HLH. Secondary HLH can delay the recognition of the underlying zoonoses. We report the case of a 61-year-old female with history of rheumatoid arthritis with histoplasmosis associated hemophagocytic lymphohistiocytosis.

    2005-08-01

    This report describes a clinical case of feline infectious peritonitis (FIP) with multisystemic involvement, including multiple nodular cutaneous lesions, in a cat that was co-infected with feline coronavirus and feline immunodeficiency virus. The skin lesions were caused by a pyogranulomatous-necrotising dermal phlebitis and periphlebitis. Immunohistology demonstrated the presence of coronavirus antigen in macrophages within these lesions. The pathogenesis of FIP involves a viral associated, disseminated phlebitis and periphlebitis which can arise at many sites. Target organs frequently include the eyes, abdominal organs, pleural and peritoneal membranes, and central nervous tissues, but cutaneous lesions have not previously been reported.

    Immunologic and occupational aspects of the susceptible population exposed to Histoplasma capsulatum, the causative agent of histoplasmosis were analyzed in the Mexican State of Guerrero. Three areas were studied, Juxtlahuaca, Olinala, and Coyuca; in the first two, their populations refer contact with bat guano and/or avian excreta, which contain nutrients for fungal growth, while the Coyuca population referred no contact with the above mentioned excreta. Previous infection with H. capsulatum was determined by histoplasmin-skin test, and the response was higher in men than in women (93.87, 85.71, and 6.6% for men, and 78.94, 66.6, and 0% for women) in Juxtlahuaca, Olinala, and Coyuca, respectively. Labor activities related to a persistent contact with the fungus were considered as an occupational risk factor, histoplasmin-skin test reached 88.57 and 36.36% of positive response in individuals with high and low risk activities. A high percentage of histoplasmin responses was observed in subjects with constant contact with H. capsulatum, such as, cave-tourist guides, peasants, and game-cock handlers, and generally they developed the largest diameter of skin reactions. Genetic risk factor was determined by studying the gene frequency of the Major Histocompatibility Complex antigens in a sample of individuals and their degree relatives in Juxtlahuaca, Olinala, and Coyuca. Significant differences were found for HLA-B22 and B17 antigens in Juxtlahuaca, and for HLA-B22 in Olinala, in comparison to the usual gene frequency observed in the normal Mexican population. HLA results were important, considering that HLA-B22 was previously found to be possibly related to pulmonary histoplasmosis in Guerrero.

    Niacin, also known as vitamin B3, is required for the synthesis of coenzymes, nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP). Niacin binds with G protein-coupled receptor (GPR) 109A on cutaneous Langerhans cells and causes vasodilation with flushing in head and neck area. Niacin deficiency due to excessive alcohol consumption, certain drugs or inadequate uptake in diet causes pellagra, a photosensitivity dermatitis. Recently several studies have revealed the mechanism of photosensitivity in niacin deficiency, which may pave a way for new therapeutic approaches. The expression level of prostaglandin E synthase (PTGES) is up-regulated in the skin of both pellagra patients and niacin deficient pellagra mouse models. In addition, pellagra is mediated through prostaglandin E₂-EP4 (PGE₂-EP4) signaling via reactive oxygen species (ROS) production in keratinocytes. In this article, we have reviewed the role of niacin in immunity and the mechanism of niacin deficiency-induced photosensitivity.

    Full Text Available Cutaneous tuberculosis because of its variability in presentation, wider differential diagnosis, and difficulty in obtaining microbiological confirmation continues to be the most challenging to diagnose for dermatologists in developing countries. Despite the evolution of sophisticated techniques such as polymerase chain reaction (PCR and enzyme-linked-immunosorbent serologic assay (ELISA, the sensitivity of new methods are not better than the isolation of Mycobacterium tuberculosum in culture. Even in the 21 st century, we rely on methods as old as the intradermal reaction purified protein derivative standard test and therapeutic trials, as diagnostic tools. We describe a case which has been diagnosed and treated as eczema by renowned physicians for 2 years. Incisional biopsy showed the presence of well-defined granulomas and ZN staining of the biopsy specimen showed the presence of acid fast bacilli; a trial of ATT (antitubercular therapy for 6 months lead to permanent cure of the lesion.

    2016-01-01

    Cutaneous scarring is common after trauma, surgery and infection and occurs when normal skin tissue is replaced by fibroblastic tissue during the healing process. The pathophysiology of scar formation is not yet fully understood, although the degree of tension across the wound edges and the speed of cell growth are believed to play central roles. Prevention of scars is essential and can be achieved by attention to surgical techniques and the use of measures to reduce cell growth. Grading and classifying scars is important to determine available treatment strategies. This article presents an overview of the current therapies available for the prevention and treatment of scars. It is intended to be a practical guide for surgeons and other health professionals involved with and interested in scar management. PMID:26909210

    Full Text Available Cutaneous leishmaniasis (CL is a widespread tropical infection caused by numerous different species of Leishmania protozoa. In our country, CL is due frequently to L. major and L. tropica. Its clinical presentation is extremely diverse. Treatment of CL aims to prevent mucosal invasion, to accelerate the healing of skin lesions, and avoid disfiguring scar. Local and physical treatment modalities including topical paromomycin, cryotherapy, localized controlled heat, carbon dioxide laser therapy, or pentavalant antimonals can be effective against. Intralesional antimonals are still the drug of choice may patients. WHO recommends an injection of drug under edges of the lesions and the entire lesion until the surface has blanched. Parenteral antimonials are useful for large, persistent or recurrent lesions. Combinations with other drugs such as allopurinol, pentoxifylline must be used for antimony unresponsive lesions.

    2016-05-01

    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.

    Disseminated glioneuronal tumors of childhood are rare. We present a retrospective IRB-approved review of the clinical course and frequency of BRAF mutations in disseminated glioneuronal tumors at two institutions. Defining features of our cohort include diffuse leptomeningeal-spread, often with a discrete spinal cord nodule and oligodendroglioma-like histologic features. Patients were identified through a pathology database search of all cases with disseminated low-grade neoplasms with an oligodendroglioma-like component. De-identified clinical information was collected by chart review and all imaging was reviewed. We retrieved the results of targeted genomic analyses for alterations in BRAF. Ten patients (aged 2-14 years) were identified from the Dana-Farber/Boston Children's Hospital and the Royal Children's Hospital, Melbourne pathology databases. Nine patients received chemotherapy. Eight patients are alive, although three have had episodes of progressive disease. We identified genomic alterations affecting the MAPK pathway in six patients. One patient had a germline RAF1 mutation and a clinical diagnosis of cardio-facio-cutaneous syndrome. BRAF duplications were identified in four and BRAF V600E mutation was identified in one. These data support the presence of targetable genomic alterations in this disease.

    Helicobacter cinaedi causes gastroenteritis and bacter-aemia, particularly in immunocompromised individuals. Although cellulitis is sometimes reported to accompany infection by this pathogen, the cutaneous manifestations are poorly understood. To clarify the characteristic cutaneous features, 47 cases of H. cinaedi bacteraemia experienced at Sapporo City General Hospital as nosocomial infection were retrospectively evaluated. Thirty-four percent (16 cases) of the patients showed cutaneous lesions. They all had sudden onset of erythemas accompanied by high temperature. The most common cutaneous manifestations were found to be superficial cellulitis, which results in painful erythemas or infiltrated erythematous plaques on the extremities. These skin lesions can be an early clinical indicator of H. cinaedi bacteraemia in the setting of nosocomial infection.

    2003-12-01

    Dissemination, the second stage of Experimental Social Innovation and Dissemination (ESID) is a critical, if not defining, element of this social change model. This paper attempts to assess the extent to which community psychology has adopted and implemented ESID's dissemination focus in its training and publications. We identify four levels of commitment to dissemination: dissemination advocate, dissemination activist, dissemination researcher, and experimental dissemination researcher. Content analyses of textbooks, journal publications, and conference papers and a brief survey of doctoral training in the field were conducted. Findings suggest that the dissemination aspects of ESID have been modestly and partially implemented within the field. That is, although there is some evidence of a commitment to dissemination practice (advocate, activist), there is much less evidence of a commitment to dissemination research. The implications of these findings for the effectiveness of the ESID model and for training and practice in community psychology are discussed.

    Cutaneous manifestations of lupus erythematosus (LE) are, usually, characteristic enough to permit an easy diagnosis. However, some patients may present less typical lesions, associated or not to the classic ones. Therefore, irrespectively of the variety of LE (acute, subacute and chronic), in absence of the typical butterfly rash, erythematosquamous papules or plaques, or any of the characteristic cutaneous alterations, it is important (even though not always easy) to recognize the uncommon and/or atypical changes of the skin.

    Leishmaniasis, is a disease that is transmitted by infected sand flies when they suck the blood of mammals. It is estimated that more than 1.5 million new cutaneous leishmaniasis (CL) cases occur throughout the world every year and the disease is endemic in southern and southeastern Turkey. Cutaneous leishmaniasis presents a spectrum of manifestations both clinically and histologically. As is in our case, histopathology can be more important than clinical examination.The diagnosis is made by ...

    The sense of force is critical in the control of movement and posture. Multiple factors influence our perception of exerted force, including inputs from cutaneous afferents, muscle afferents and central commands. Here, we studied the influence of cutaneous feedback on the control of ankle force output. We used repetitive electrical stimulation of the superficial peroneal (foot dorsum) and medial plantar nerves (foot sole) to disrupt cutaneous afferent input in 8 healthy subjects. We measured the effects of repetitive nerve stimulation on (1) tactile thresholds, (2) performance in an ankle force-matching and (3) an ankle position-matching task. Additional force-matching experiments were done to compare the effects of transient versus continuous stimulation in 6 subjects and to determine the effects of foot anesthesia using lidocaine in another 6 subjects. The results showed that stimulation decreased cutaneous sensory function as evidenced by increased touch threshold. Absolute dorsiflexion force error increased without visual feedback during peroneal nerve stimulation. This was not a general effect of stimulation because force error did not increase during plantar nerve stimulation. The effects of transient stimulation on force error were greater when compared to continuous stimulation and lidocaine injection. Position-matching performance was unaffected by peroneal nerve or plantar nerve stimulation. Our results show that cutaneous feedback plays a role in the control of force output at the ankle joint. Understanding how the nervous system normally uses cutaneous feedback in motor control will help us identify which functional aspects are impaired in aging and neurological diseases.

    A 12-year-old female black-masked lovebird (Agapornis personata) with a cobalt color mutation was presented for self-mutilation of a mass located on the right lateral neck. Cytologic evaluation of the soft tissue mass revealed a predominance of poorly stained mast cells with metachromatic intracytoplasmic granules. The presumptive diagnosis was cutaneous mast cell tumor. Clinical evaluation, results of a complete blood cell count and biochemical analysis, and radiographs did not reveal systemic manifestation of mast cell disease. The mass was surgically resected, but surgical margins were limited because of the location of the mass and the small size of the patient. The lovebird died the day after surgery. Gross postmortem examination revealed splenomegaly, multifocal pinpoint white nodules throughout the liver parenchyma, severe thickening and yellow coloration of the great vessels, and pale pink swelling of the caudal right kidney. Histopathologic analysis of the resected mass revealed sheets of round cells that contain metachromatic granules, defined as neoplastic mast cells, within a fine fibrovascular stroma. Similar neoplastic cells were seen in the right kidney, hepatic sinusoids, splenic pulp, periovarian connective tissue, and bone marrow. The histopathologic diagnosis was a cutaneous mast cell tumor and disseminated mast cell disease, or mastocytosis. To the authors' knowledge, this is the first reported case of a cutaneous mast cell tumor and mastocytosis in a psittacine bird.

    Cutaneous malignant melanoma is an aggressive type of skin cancer which causes disproportionate mortality in young and middle-aged adults. Once disseminated, melanoma can be considered an incurable disease, highly resistant to standard antineoplastic treatment, such as chemotherapy or radiation therapy. The proteasome represents a novel target for cancer therapy that can potentially be used in melanoma. To assess the effect of four structurally different proteasome inhibitors on human cutaneous melanoma-derived cell lines. Sixteen human cutaneous melanoma-derived cell lines which are original were obtained from patients who were treated by two of the authors. Cells were cultured, exposed to proteasome inhibitors (bortezomib, ALLN, MG-132 and epoxomicin) and then assayed for cell cycle and cell death analyses. Proteasome inhibitors inhibited the in vitro growth of melanoma cells, and this effect was due to a reduction in cell proliferation rate and an induction of both caspase-dependent and caspase-independent cell death. Moreover, release of apoptosis-inducing factor was observed in the presence of the broad-specificity caspase inhibitor BAF (Boc-D-fmk). In addition, the four different proteasome inhibitors induced caspase 2 processing. This study provides information regarding the in vitro effects of proteasome inhibitors on melanoma cell lines, and the molecular mechanisms involved. It also gives support to the future use of such inhibitors in the treatment of patients with melanoma, either administered alone or in combination with other drugs.

    2002-11-01

    A case of angioinvasive cutaneous mucormycosis in a premature infant, eventually requiring extracorporeal membrane oxygenation therapy, is described. The fungal infection began at the site of a brachial artery catheter that had been covered with an adhesive dressing in the left antecubital fossa. The infection progressed rapidly over a 5-day period, and a left arm amputation was required. Fungal hyphae were present at the margins of resection. The patient eventually had disseminated mucormycosis and died. A second case of cutaneous mucormycosis in another premature infant also is presented. This infant had the infection at an intravenous catheter site. Rapid initiation of surgical debridement of the wound and amphotericin B therapy resulted in patient survival. Eighteen reported cases of cutaneous mucormycosis in neonates were found and are reviewed. Prematurity, low birth weight, broad-spectrum antibiotics, corticosteroid therapy, and local trauma to the skin site were common risk factors. Only 7 of the 18 patients survived. Therapy consisted of local debridement and intravenous amphotericin B. High index of suspicion, early diagnosis, and rapid institution of therapy can improve survival rate. The key to prevention appears to be appropriate skin care. Copyright 2002, Elsevier Science (USA). All rights reserved.

    A 92-year-old man presented with months of progressive blurry vision, worsening acutely in his right eye. He denied pain, diplopia, or photopsias. His history was significant for multiple myeloma, prostate cancer, and malignant melanoma of his right shoulder treated with local excision. He had local recurrence with hepatic metastasis of the melanoma treated with radiation and chemotherapy. On examination, his visual acuity was counting fingers in the right eye and 20/60 in the left eye. Amsler grid testing demonstrated metamorphopsia in the right eye. Fundus exam of the right and left eyes revealed multiple, elevated, pigmented choroidal lesions, with associated subretinal fluid in the right macula. This appearance is consistent with hematogenous metastasis of cutaneous malignant melanoma to the choroid and associated serous fluid-causing metamorphopsia. The patient was enrolled in a clinical trial combining plasmid IL-12 with pembrolizumab (Keytruda; Merck, Whitehouse Station, NJ). He passed away 2 months after initial presentation to our clinic.

    2008-04-01

    Cutaneous leishmaniasis is an endemic disease with increasing incidence, even in Europe. Recently, it has attracted more attention due to reactivation in immunocompromised hosts, e.g. in the context of HIV. Therapeutic options range from topical treatment to systemic therapy for more complex cases. A vaccine does not exist at present. Despite of several attempts, vaccine generation has proven to be difficult even though protective immunity against this obligate intracellular protozoan parasite is dependent on the development of antigen-specific CD4+ and CD8+ T cells capable of releasing IFN?. IFN?, in turn, activates phagocytic host cells to generate oxidative radicals and to eliminate the parasite. This review will describe the basic immunology leading to the development of protective immunity in infected individuals. In addition, the authors will focus on highlighting the different approaches utilized for vaccine development and describe what a efficient vaccine may consist of. Combined intensive research in the fields of basic parasitology and immunology may allow for the generation of an efficacious vaccine against this important human pathogen in the near future.

  19. [Mechanisms of cutaneous drug reactions].

    Science.gov (United States)

    Vaillant, L

    2000-06-15

    Two main mechanisms, pharmacologic and immunoallergic, are responsible for cutaneous reactions to drugs. Pharmacologic mechanisms can be predictable (overdosage, cumulative or delayed toxicity, adverse effects) or unpredictable (idiosyncratic, intolerance, or anaphylactic reaction). Immunoallergic mechanisms can be mediated by IgE (some types of urticaria and anaphylactic shock), due to circulating immune complexes (leukocytoclastic vasculitis, serum sickness-type reactions) or mediated by lymphocytes (exanthema, Lyell's syndrome, fixed pigmented erythema, photosensitization). The diagnostic work-up varies according to the causative mechanism. When the reaction is predictable, the responsible drug can be identified according to the data in the present bibliography. When the reaction is immunologic, only the chronologic sequence of events can identify the responsible drug. The risk of recurrence with an identical or related molecule also varies according to the causative mechanism. For urticaria, diagnosis and the risk of recurrence differ according to whether the cause is allergic (mediated by IgE or urticarial vasculitis) or is pharmacologic (urticaria due to aspirin or to conversion enzyme inhibitors).

    We report two cases of cutaneous cryptococcosis in male patients without underlying disease. Case 1 had a granulomatous mass on his right neck, gradually enlarging for 3 months. After the mass was debrided surgically in a hospital, the incision wound gradually developed into a severe ulceration. Mycological examination revealed Cryptococcus neoformans infection. It was significant that histopathology of both pre-surgery granuloma and post-surgery ulceration revealed thick-walled spores with thick capsule. Chest X-ray revealed a shadow in the left lower lung. After treatment with amphotec for 21 days, the lesion healed. Case 2 had an approximately 2 x 2 cm solitary dull nodule on his right thigh, which had been present for 8 months. Mycological examination confirmed that the lesion was caused by C. neoformans. The patient's ratio of peripheral blood CD4(+) cell was slightly reduced. After 14 days of treatment with oral fluconazole, followed by oral itraconazole for 2 months, mycological and clinical cure were achieved. The two isolates were identified as C. neoformans var. gattii serotype C and C. neoformans var. grubii serotype A.

    China is a country that experiences a large number of disasters. The number of deaths caused by large-scale disasters and accidents in past 10 years is around 900,000. More than 92.8 percent of these deaths could be avoided if there were an effective pre-warning system deployed. Knowledge of the information dissemination characteristics of different information media taking into consideration governmental assistance (information published by a government) in disasters in urban areas, plays a critical role in increasing response time and reducing the number of deaths and economic losses. In this paper we have developed a comprehensive information dissemination model to optimize efficiency of pre-warning mechanics. This model also can be used for disseminating information for evacuees making real-time evacuation plans. We analyzed every single information dissemination models for pre-warning in disasters by considering 14 media: short message service (SMS), phone, television, radio, news portals, Wechat, microblogs, email, newspapers, loudspeaker vehicles, loudspeakers, oral communication, and passive information acquisition via visual and auditory senses. Since governmental assistance is very useful in a disaster, we calculated the sensitivity of governmental assistance ratio. The results provide useful references for information dissemination during disasters in urban areas.

    There were only a few reports of mercury on pulmonary artery. However, there is no data on surgery related mercury dissemination. The objective of the present article is to describe one case of postoperative injected mercury dissemination. A 19-year-old man presented severe neck pain including meningeal irritation sign and abdominal pain after injection of mercury for the purpose of suicide. Radiologic study showed injected mercury in the neck involving high cervical epidural space and subcutaneous layer of abdomen. Partial hemilaminectomy and open mercury evacuation of spinal canal was performed. For the removal of abdominal subcutaneous mercury, C-arm guided needle aspiration was done. After surgery, radiologic study showed disseminated mercury in the lung, heart, skull base and low spinal canal. Neck pain and abdominal pain were improved after surgery. During 1 month after surgery, there was no symptom of mercury intoxication except increased mercury concentration of urine, blood and hair. We assumed the bone work during surgery might have caused mercury dissemination. Therefore, we recommend minimal invasive surgical technique for removal of injected mercury. If open exposures are needed, cautious surgical technique to prohibit mercury dissemination is necessary and normal barrier should be protected to prevent the migration of mercury.

    Full Text Available Over the last three decades, China’s agriculture sector has been transformed from the traditional to modern practice through the effective deployment of Information and Communication Technologies (ICTs. Information processing and dissemination have played a critical role in this transformation process. Many studies in relation to agriculture information services have been conducted in China, but few of them have attempted to provide a comprehensive review and analysis of different information dissemination models and their applications. This paper aims to review and identify the ICT based information dissemination models in China and to share the knowledge and experience in applying emerging ICTs in disseminating agriculture information to farmers and farm communities to improve productivity and economic, social and environmental sustainability. The paper reviews and analyzes the development stages of China’s agricultural information dissemination systems and different mechanisms for agricultural information service development and operations. Seven ICT-based information dissemination models are identified and discussed. Success cases are presented. The findings provide a useful direction for researchers and practitioners in developing future ICT based information dissemination systems. It is hoped that this paper will also help other developing countries to learn from China’s experience and best practice in their endeavor of applying emerging ICTs in agriculture information dissemination and knowledge transfer.

    Full Text Available Disseminated tuberculosis is a common mode of presentation of tuberculosis in patients both with and without HIV/AIDS in India. However, primary multidrug resistance in disseminated tuberculosis involving only the extrapulmonary sites in an immunocompetent adult is rare. Here, we report a case of a 19-year-old man who had disseminated tuberculosis involving left pleura, pericardium, peritoneum and intraabdominal lymph nodes. He was initially taking WHO category I antituberculous drugs, but was not responding in spite of 5 months of chemotherapy. Culture of the pleural biopsy specimen grew Mycobacterium tuberculosis which was resistant to isoniazid and rifampicin. He was put on therapy for multidrug resistant tuberculosis,following 24 months of chemotherapyhe had an uneventful recovery.

    Full Text Available Pineal parenchymal tumors are rare. Of the three types of pineal parenchymal tumors, pineocytomas are the least aggressive and are not known to diffusely disseminate. In this paper, we report the successful treatment of a case of pineocytoma with diffuse leptomeningeal relapse following initial stereotactic radiotherapy. A 39-year-old female presented with headaches, balance impairment, urinary incontinence, and blunted affect. A pineal mass was discovered on magnetic resonance imaging (MRI. A diagnosis of pineocytoma was established with an endoscopic pineal gland biopsy, and the patient received stereotactic radiotherapy. Ten years later, she developed diffuse leptomeningeal dissemination. The patient was then successfully treated with craniospinal radiation therapy. Leptomeningeal spread may develop as late as 10 years after initial presentation of pineocytoma. Our case demonstrates the importance of long-term follow-up of patients with pineal parenchymal tumors following radiation therapy, and the efficacy of craniospinal radiation in the treatment of leptomeningeal dissemination.

The first challenge of Eurostat is clearly to know what users want: we know our different types of users but we have to identify how they get our data, what they do with our data, how they react to our outputs and which sort of new service they would like us to propose. Translating these needs into a visual dissemination is a new challenge undertaken by Eurostat through a new portal, new mobile apps and new info graphs and basic application as well as increasing the visibility on Google. The objective of this paper is to share Eurostat's experience in identifying user Leeds and to show how concretely this information has been visually disseminated.

Neurocysticercosis (NCC is the most common manifestation of the disease involving the central nervous system (CNS. One of the uncommon manifestations of cysticercosis is its disseminated form. The most commonly affected organs are the subcutaneous tissues, skeletal muscles, lungs, brain, eyes, liver, and occasionally the heart, thyroid, and pancreas but in widespread dissemination it can involve any organ in the body. We report here a case of a 35-year-old-female with disseminated cysticercosis (DCC. She attended our hospital with headache, fever, and symptoms of multiple palpable nodules. After the investigations, she was diagnosed with DCC involving the brain and subcutaneous tissues all over the body. Then she was successfully treated with albendazole and steroids.

    2017-04-01

    Dissemination and Exploitation are essential parts of public funded projects. In Horizon 2020 a plan for the exploitation and dissemination of results (PEDR) is a requirement. The plan should contain a clear vision on the objectives of the project in relation to actions for dissemination and potential exploitation of the project results. The actions follow the basic idea to spread the knowledge and results gathered within the project and face the challenge of how to bring the results into potentially relevant policy circle and how they impact the market. The plan follows the purpose to assess the impact of the project and to address various target groups who are interested in the project results. Simply put, dissemination concentrates on the transfer of knowledge and exploitation on the commercialization of the project. Beyond the question of the measurability of project`s impact, strategies within science marketing can serve purposes beyond internal and external communication. Accordingly, project managers are facing the challenge to implement a dissemination and exploitation strategy that ideally supports the identification of all partners with the project and matches the current discourse of the project`s content within the society, politics and economy. A consolidated plan might unite all projects partners under a central idea and supports the identification with the project beyond the individual research questions. Which applications, strategies and methods can be used to bring forward a PEDR that accompanies a project successfully and allows a comprehensive assessment of the project afterwards? Which hurdles might project managers experience in the dissemination process and which tasks should be fulfilled by the project manager?

    Primary cutaneous follicle center lymphoma (pcFCL) is an indolent type of primary cutaneous B-cell lymphoma (pcBCL) rarely disseminating to other organs. PcBCL with spindle-cell morphology has been described as a rare variant of pcFCL but the prognosis data of this variant is sparse. We report a rare case of spindle-cell pcFCL with CD20(+), CD79a(+), CD3(+), Bcl-6(+), Mum-1(-) and CD10(-) tumor cells that infiltrated the hepatic hilum, mimicking a Klatskin tumor. On the basis of the sparse published data on spindle-cell morphology of pcBCL, this growth pattern should elicit awareness of an increased risk of systemic involvement in the otherwise indolent pcFCL.

    2016-10-01

    Familial amyloid polyneuropathy (FAP) is a rare inherited autosomal dominant form of systemic amyloidosis, which classically presents with severe motor, sensory, and autonomic dysfunction. Cutaneous involvement does not become clinically apparent until late stage symptomatic disease and is rarely reported in modern literature. Here, the authors review the clinical and histologic cutaneous findings of FAP previously described in the literature and report on 3 patients with unique genetic mutations (Thr60Ala and Gly6Ser; Trp41Leu; Glu89Gln) for which cutaneous involvement has not previously been described. Histologically, our patients showed variable amyloid deposition in the subcutaneous adipose tissue, papillary dermis, and dermal blood vessel walls. A review of the literature suggests cutaneous transthyretin deposition is an underrecognized feature of FAP that occurs early on in disease, even before neural involvement and related symptoms as seen in one of our patients. As such, a cutaneous punch biopsy can serve as quick, easy, and relatively noninvasive diagnostic tool in suspected cases.

    Cutaneous ciliated cyst was described as a painless cyst occurring on the lower limbs of women between the ages of 15 and 30 years. The cysts are typically lined by ciliated cuboidal to columnar epithelium with pseudostratified areas and focal squamous metaplasia is occasionally present. Immunohistochemical studies have demonstrated that the cysts are PR and ER positive, similar to the epithelia of the fallopian tubes. However, outliers of cutaneous ciliated cysts, including those in male patients and in unexpected locations such as the scalp, finger, and scapular area, have been reported. Thus, some hypotheses have been proposed including the Mullerian heterotopias, ciliated metaplasia of eccrine sweat glands, and embryonic remnants of the cloacal membrane. We report a rare case of cutaneous ciliated cyst on the left shoulder of a 7-year-old boy and this is the eighth case of cutaneous ciliated cyst in male patients. Moreover, through reviewing the articles, we try to propose the classification of the cutaneous ciliated cysts into the cutaneous Mullerian cysts and the ciliated cutaneous eccrine cysts.

    2016-10-01

    Pleuroparenchymal fibroelastosis (PPFE) is a rare progressive disease that manifests as parenchymal fibrosis of the upper lobe and pleura. Approximately 100 cases have been reported. Cutaneous manifestations of PPFE have not previously been described. Diagnosis is dependent on histologic identification of fibrosis with atypical elastic fibers, necessitating an invasive peripheral lung wedge biopsy.A 68-year-old male with a history of pleuroparenchymal fibroelastosis presented with an asymptomatic, telangiectatic erythematous eruption on bilateral lower extremities. Biopsies demonstrated a subtle perivascular infiltrate with marked increase in atypical elastic fibers, similar to the elastosis in the patient's lungs.This is the first documented case of cutaneous manifestations in PPFE. Clinicians need to be aware that cutaneous eruptions clinically simulating telangiectasia macularis eruptiva perstans but lacking a mast cell infiltrate histologically, may have increased abnormal elastic fibers. Thus, early recognition of these lesions in patients with an undefined restrictive lung disorder, may facilitate the diagnosis of PPFE in some patients.

    Cellular and non-cellular constituents of skin contain fundamental morphometric features and structural patterns that correlate with tissue function. High resolution digital image acquisitions performed using an automated system and proprietary software to assemble adjacent images and create a contiguous, lossless, digital representation of individual microscope slide specimens. Serial extraction, evaluation and statistical analysis of cutaneous feature is performed utilizing an automated analysis system, to derive normal cutaneous parameters comprising essential structural skin components. Automated digital cutaneous analysis allows for fast extraction of microanatomic dat with accuracy approximating manual measurement. The process provides rapid assessment of feature both within individual specimens and across sample populations. The images, component data, and statistical analysis comprise a bioinformatics database to serve as an architectural blueprint for skin tissue engineering and as a diagnostic standard of comparison for pathologic specimens.

    Mastocytosis is a heterogeneous disorder characterized by clonal proliferation and accumulation of mast cells in one of more organs which may lead to different clinical pictures. Pathological increase and activation of mast cells in various tissues can cause different clinical pictures. Cutaneous mastocytosis limited to the skin is the most typical clinical picture observed in children and systemic mastocytosis is very rare in the pediatric age group. The diagnosis of cutaneous mastocytosis is based on clinical findings, but is often delayed due to lack of clinical awareness of the disease and lack of its consideration in the differential diagnosis. This article focuses on the current diagnosis, management and treatment of cutaneous mastocytosis in children in order to increase awareness about this issue.

    Cutaneous lupus erythematosus (CLE) is a disease with different subtypes and the new classification system includes acute CLE (ACLE), subacute CLE (SCLE), chronic CLE (CCLE), and intermittent CLE (ICLE). The broad spectrum of skin involvement and the possibility of systemic organ manifestations at the beginning and during the course of CLE require specific diagnostic procedures. Clinical assessment of the cutaneous manifestations is necessary along with a detailed patient's history. The diagnosis of CLE is confirmed by histopathology and immunofluorescence microscopy. Selective laboratory screening and additional diagnostic procedures depending on clinical symptoms are recommended. Photoprovocation tests can be performed to assess photosensitivity in patients with CLE and to support the diagnosis. Recently, a scoring system for the activity of the cutaneous manifestations in CLE has been developed and is now evaluated in several clinical studies. In this review, the classification and the characteristic clinical criteria of the different CLE subtypes as well as the current diagnostic possibilities are emphasized.

    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.
