    Neurocutaneous melanosis is a rare disorder characterized by the presence of a large or multiple congenital melanocytic nevus with proliferation of melanocytes in the central nervous system. The prognosis of neurocutaneous melanosis is extremely poor and its diagnostic approach requires understanding its brain magnetic resonance imaging findings. We report a patient with asymptomatic neurocutaneous melanosis and its radiologic findings.

    Melanosis observed in association with prolonged chlorpromazine therapy has become a serious problem in mental institutions. Skin pigmentation has produced an appearance which is cosmetically undesirable. Ocular deposits have caused visual impairment. Diffuse visceral involvement has been accompanied by functional disturbances of the involved organs. Withholding chlorpromazine did not diminish the pigment deposits already present in eight patients with chlorpromazine-induced melanosis. Therefore therapy for existing cases and means of preventing this side effect were investigated. A method of blocking melanin synthesis by depressing tyrosinase activity was devised. A copperchelating agent, D-penicillamine, was administered for a period of four weeks (300 mg. three times daily for six days each week, with mineral supplement substituted on the seventh day). Four of six days patients thus treated improved markedly as evidenced by diminution of skin pigmentation. Urinary copper excretion was substantially increased during the trial period. An alternative method of treatment designed to stimulate melatonin production by the pineal gland was employed. Two patients were kept in darkness for a period of four weeks. One improved markedly, the other only slightly. PMID:14201250

    Full Text Available Mucosal lesions due to underlying disease or drug toxicity, are important part of oncology practice. Patient with a diagnosis of hepatocellular carcinoma was treated with chemoembolisation. She presented with new onset of mucosal hyperpigmented lesion all through her oral cavity. Biopsy was consistent with mucosal melanosis, which was associated with the chemotherapeutics used in the chemoembolisation procedure. Lesion progressively improved without any treatment. Here we present an mucosal melanosis experience after chemoembolisation. J Clin Exp Invest 2015; 6 (2: 189-191

    Full Text Available We report a 3-year-old girl born with fair complexion which became darker. The color change was insidious in onset at the age of 5 months, asymptomatic and progressive involving the entire body surface. Histopathology revealed increased pigmentation of the epidermal basal layer. Universal acquired melanosis is a rare form of hypermelanosis which was synonymously referred to as "Carbon baby". This is a rare presentation with only one earlier case report.

    Full Text Available Intoduction: Melanosis coli is a benign lesion affecting the mucosa of the large intestine. There is a relationship between the presence of melanosis and anthraquinone laxative use. Melanosis coli is also observed in patients with colon cancer, but there is doubt whether these two conditions are related. Aim : To analyze the correlation between melanosis and colon cancer. Material and methods: We analyzed retrospectively 436 patients undergoing colon cancer surgery. There were 246 women and 190 men. Patients were divided into three age groups: under 50 years, between 51 and 65 years, and over 66 years. We analyzed sections of the cancer and intestinal mucosa from the tumor’s proximal (2–5 cm and distal (8–10 cm zone. Results : Melanosis coli was present in 52 patients, which represents 11.9% of patients with colon cancer. More often it was present in women. The most common location of melanosis and colon cancer was the terminal part of the large intestine. In patients below 50 years of age in both sexes melanosis coli did not occur. In men, melanosis was more common in the age group over 66 years. Intensity of pigmentation was higher in the tumor’s distal zone. Conclusions : The incidence of melanosis coli increases with age, similar to that of colon cancer. Melanosis was not present inside tumors, in almost half of the cases it was not present in the proximal zone, and the degree of pigmentation increased in distal zone. The cause-effect relationship between melanosis coli and colon cancer remains uncertain.

    Full Text Available OBJECTIVE The aim of the present study was to analyse different clinical patterns of frictional melanosis and to evaluate whether sun exposure is a causative or contributing factor for frictional melanosis. Furthermore, histopathology with haematoxylin and eosin along with special stains for amyloid like Congo red was done. METHODS 50 patients with clinical diagnosis of frictional melanosis participated in this study. INCLUSION CRITERIA Patients of all ages and both sexes with classical clinical features suggestive of frictional melanosis are included. EXCLUSION CRITERIA Patients having pigmentation over areas where the frictional melanosis presents classically but have been using chemicals, hair dyes and other agents which can cause photocontact dermatitis have been excluded from the study. A detailed history regarding duration of illness, progression and precipitating factors along with detailed clinical examination regarding the location of the lesions and type of lesions was done and patients were subjected to skin biopsy after obtaining a written consent. RESULTS Out of 50 cases, 39 (78% were confirmed with histopathology as frictional melanosis and 11(22% as macular amyloidosis. Among patients of frictional melanosis, 56.41% had only skin lesions. In macular amyloidosis 63.63% patients had itching along with skin lesions. In Frictional melanosis the most frequently involved site was extensor aspect of arm (78.48%. The most frequently involved site in macular amyloidosis was extensor aspect of forearm (93.34%. CONCLUSION In this study a total number of 50 patients with clinical presentation of frictional melanosis were analysed with female preponderance. Amyloid deposition is seen in those skin biopsy specimens taken from area of friction with sun exposure, which suggests that sun exposure could be one of the predisposing factors for macular amyloidosis. Thus, these findings confirm that frictional melanosis is a variant of macular

    Deposition of pigment in the intestinal mucosa is commonly observed by the endoscopist, especially within the colon, and particularly during investigations for constipation. Pigment may also be detected in the small intestine. Although labeled as melanosis, electron microscopy and X-ray analytical methods have provided evidence that this pigment is not melanin at all, but lipofuscin. Often, herbal remedies or anthracene containing laxatives are often historically implicated, and experimental studies in both humans and animal models have also confirmed the intimate relationship with these pharmacological or pseudo-pharmacological remedies. The appearance of melanosis coli during colonoscopy is largely due to pigment granule deposition in macrophages located in the colonic mucosa. The pigment intensity is not uniform, being more intense in the cecum and proximal colon compared to the distal colon. Possibly, this reflects higher luminal concentrations of an offending agent in the proximal compared to distal colon, differential absorption along the length of the colon, or finally, differences in macrophage distribution within the colon. Mucosal lymphoid aggregates normally display a distinct absence of pigment producing a "starry sky" appearance, especially in the rectosigmoid region. Interestingly, some focal, usually sessile, colonic mucosal neoplastic lesions, rather than submucosal lesions, may be better appreciated as pigment deposition may be absent or limited. If detected, removal and further histopathologic analysis of the polyp may be facilitated.

    Full Text Available Abstract Background Melanosis Coli is described as black or brown discolouration of the mucosa of the colon. Its a benign condition, which arises from anthraquinone laxative abuse and has no symptoms of its own. The main importance of diagnosing Melanosis Coli correctly lies in the fact that if its extensive, there may be difficulty in differentiating it from ischemic colitis. Case presentation We present a case of extensive Melanosis Coli involving the whole of large bowel that appeared gangrenous. A sub total colectomy was performed on presumed diagnosis of ischemic bowel. Conclusion This report reminds the clinicians that extensive Melanosis Coli may mimic ischemic colitis and thus must be considered as a differential diagnosis.

    Full Text Available Transient neonatal pustular melanosis is mostly found in full-term black infants. It is a benign and self-limited disease, and the etiology is still unknown. We present a full-term female neonate with multiple vesiculopustular and pigmented macular lesions found immediately after her birth. A skin biopsy showed vesicles consisting of intracorneal and subcorneal aggregates of neutrophils, which is compatible with transient neonatal pustular melanosis. Although it is rare in Taiwan and Asian countries, transient neonatal pustular melanosis should always be considered when pustulosis is found in the neonatal period to prevent the use of unnecessary antibiotics. Dermatological consultation and histological confirmation are sometimes required for the final diagnosis.

    Full Text Available Colon melanosis is a rare pathology which is connected with a long intake of non-steroid anti-inflammatory medicines or purgative drugs containing antraglycozides. Colon melanosis is also detected at liver and pancreas diseases and colon cancer. The disease is rare for children. The article features a clinical observation of a melanosis case in a 15-year-old girl who suffered from constipation and had been taking senna drugs as purgatives without control for 6 months. The diagnosis was founded on the endoscopic image and was confirmed by a histological survey of the colon mucous.

    Our previous study has shown that cryogun cryotherapy is a good and effective treatment modality for oral leukoplakia. In this study, we used cryogun cryotherapy to treat 72 oral leukoplakia and adjacent smoking-induced melanosis (OLM) lesions on the buccal mucosae. Of 72 OLM lesions, 14 had epithelial hyperplasia with parakeratosis, 24 had epithelial hyperplasia with hyperkeratosis, 26 had mild dysplasia, seven had moderate dysplasia, and one had severe dysplasia. Complete regression was achieved in all 72 OLM lesions after a mean of 3.3 ± 1.3 cryogun cryotherapy treatments. We found that OLM lesions in patients without smoking habit, with the greatest diameter cryotherapy treatment to achieve complete regression than those OLM lesions in patients with smoking habit, with the greatest diameter ≥ 2.8 cm, without epithelial dysplasia, or with a surface keratin thickness > 50 μm (all P-values cryotherapy treatment number (all P-values cryotherapy treatment required to achieve complete regression of the OLM lesion by multivariate logistic regression analyses. Cryogun cryotherapy is an effective treatment modality for OLM lesions. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2017-08-01

    Full Text Available We present a 74-year-old male patient with 3-years history of visible discoloration of the glans penis, without subjective complaints. Histopathological examination after incision biopsy revealed a moderate increase in the number of melanocytes in the basal layer with irregular distribution, without melanocytic nests, melanophages in the superficial dermis, and subepidermal sclerosus. No cytologic atypia of melanocytes was detectable. The diagnosis of melanosis of the genitalia in association with lichen sclerosus was made. The importance of the presented cases implicated the unique clinical manifestation of penile melanosis, associated with lichen sclerosus of the penis in one hand, the essential differentiation between malignant melanoma via careful histological examination for diagnosis confirmation in other, in order to optimize the therapeutic behavior.

    To determine the hedgehog (Hh) signaling pathway correlated with the development of colon cancer and melanosis coli. Protein and mRNA levels of Hh signaling pathway components (sonic hedgehog [Shh], protein patched homolog 1 [Ptch 1], GLI family zinc finger 1 [Gli 1] and suppressor of fused homolog [Drosophila] [Sufu]) in 127 patients with colon cancer, 36 with melanosis coli and 20 adjacent normal mucosal tissues taken from surgical specimens were evaluated using antibody staining and quantitative real-time polymerase chain reaction. In adjacent normal tissue Shh and Ptch1, but not Gli1 or Sufu, were weakly expressed and mainly in the lining epithelium of the colonic mucosa. In cancerous tissues Shh and Gli1 were uniformly strong while Ptch1 was patchy and weak, and Sufu uniformly weak, which paralleled their levels of corresponding mRNA. Elevated protein levels of Shh and Ptch were significantly associated with mucinous colonic tissues. Elevated Sufu protein levels were positively correlated with the diameter and invasion of the tumor. In patients with melanosis coli, mRNA levels of Shh, Ptch1, Gli1 and Sufu were very low, which was similar to those of adjacent normal tissues; but protein levels of Shh, Ptch1 and Gli1, but not Sufu, were high, which was similar to those of cancerous tissues. The mRNA and protein levels of Hh pathway components are aberrantly elevated in colon cancer, which may be the potential molecular classification markers. Further studies are required to determine the role of melanosis coli in the colon tumorigenesis. © 2013 The Authors.

    Riehl's melanosis, a form of dermatitis characterized by reticulate pigmentation, typically presents as a gray-brown to black hyperpigmentation on the face and neck. Among the various etiologic factors suggested, photoallergic reaction and pigmented contact dermatitis resulting from exposure to drugs, coal tar dyes, optical whitener, or other ingredients found in cosmetics are believed to be the major contributing factors in this disease. The histopathological features of Riehl's melanosis mainly consist of pigmentary incontinence along with infiltration of numerous dermal melanophages and lymphohistiocytes.1,2 Additionally, notable clinical improvements in the treatment of this condition have been reported for intense pulsed light (IPL) therapy, in comparison to long-term topical application of bleaching agents.2 Here, we report the cases of two Asian patients treated with a low-pulse energy 1,064-nm Q-switched (QS) Nd:YAG laser for hair dye-induced Riehl's melanosis on the face and neck. In conclusion, we observed that Riehl's melanosis on the face and neck was effectively and safely treated with a low-pulse energy 1,064-nm QS Nd:YAG laser. We suggest that this method can be used in Asian patients with Riehl's melanosis at risk of postinflammatory hyperpigmentation from excessive light or laser energy delivery.

    Melanocytic meningeal tumours are rare extra-axial neoplasms of the nervous system, with only three reported cases in the cavernous sinus. Herein we describe for the first time the association of ocular melanosis and multiple intracranial melanocytic meningeal tumours, with the presenting lesion being in the cavernous sinus. The importance of this association is discussed together with the diagnostic and therapeutic challenges of the case. A 20-year-old man presented with a left sixth cranial nerve deficit; general examination documented only congenital melanosis of the homolateral eye. MRI examination showed a space occupying lesion in the left cavernous sinus, which was followed conservatively for 2 years, until a new space occupying lesion was evident at the level of the right frontal convexity: both lesions presented with neuroradiological characteristics suggestive of melanin content. The frontal convexity lesion was removed: intraoperatively the dura was markedly and diffusely melanotic. Histological examination documented a melanocytic meningeal tumour, with a proliferative index of 3 %. The patient underwent 3D-Conformal Radiation Therapy on the lesion of the cavernous sinus (total dose 5040 cGy), with initial tumour reduction. Three years later, due to a symptomatic growth, he underwent partial removal of the lesion in the cavernous sinus. Histological examination was unchanged. He then received adjuvant Temozolomide with Low Dose Fractionated Radiation Therapy (LD-FRT). Due to further disease progression cisplatin plus fotemustine were administered, concomitant with LD-FRT: after two cycles MRI documented significant disease regression. After a period of apparent disease control, the patient presented with persistent cough and evidence of multiple thoracic metastases, which lead to his death, seven years after presentation. Intracranial melanocytic meningeal tumours are challenging lesions, both from a diagnostic and therapeutic point of view; though rare

    Full Text Available ABSTRACTWe report a case of primary acquired corneal melanosis without atypia associated with corneal haze in a patient with a history of limbal malignant melanoma and the effect of mitomycin-C. A 75-year-old woman with a history of limbal malignant melanoma presented with loss of vision in right eye. Corneal examination showed a patchy melanotic pigmentation with a central haze. Topical mitomycin-C improved visual acuity and corneal haze. However, the pigmented lesions persisted, and they were removed with alcohol corneal epitheliectomy. Histopathological examination demonstrated primary acquired melanosis without atypia. The lesions were successfully removed, and there were no recurrences during the follow-up period of 36 months. The association of conjunctival and corneal melanosis without atypia is a rare condition. In addition, co-existence of central corneal haze and melanosis may decrease visual acuity. Topical mitomycin-C and alcohol corneal epitheliectomy can be useful treatments in this condition.

    Vyanga is one of the Kshudraroga, characterized by the presence of Niruja (painless) and Shavavarna Mandalas (bluish-black patches) on face. It is one of the most common diseases as regards the face is concerned. On the basis of clinical features, it can be compared with facial melanosis, one of the hyper pigmented disorders. Drugs with Rakta Prasadaka, Twak Prasadaka and Varnyakara properties are helpful in the management of Vyanga, that pacifies aggregated Doshas and help in Raktashodhana (blood purification). To evaluate the efficacy of Arjunatwak Lepa and Panchanimba Churna in Vyanga. In this study, the trial drugs used were Arjunatwak Churna for Lepa (tropical application) and Panchanimba Churna for oral administration. A total 30 patients of Vyanga were selected from outpatient department and inpatient department of Shalakya Tantra Department and allotted randomly in two groups. In group-A, the patients were treated with external application of Arjunatwak Churna and Madhu for 21 days, while in group-B, patients received Panchanimba Churna orally for 21 days in addition to Arjunatwak Churna for Lepa. Effect of therapy on chief complaint i.e., bluish-black pigmentation in Group A was 60% relief, while in Group B 80% relief was found. The clinical study has shown that combined therapy gives better results than topical treatment.

    To explore the clinical characteristics of neurocutaneous melanosis (NCM) in adult patients in order to help improve diagnosis and treatment of this disease. We present a rare case of an adult patient suffering from neurocutaneous melanosis with malignant melanoma as well as a review Chinese and English literature, and analyze their clinical features. There were thirty adult NCM patients, aged 19 to 65 years old, average 27.9 years old, twenty males (66.7%), ten females (33.3%); Twenty-four cases of malignant melanoma (80.0%), three cases of melanocytoma (10.0%), two cases of diffuse melanocytosis (6.7%), and one case pathology unknown (3.3%). Twenty-five cases showed satellite nevi (83.3%), five cases unknown (16.7%). Twenty-eight cases had intracranial lesions (93.3%) and two cases had intraspinal lesions (6.7%). Four cases combined hydrocephalus (13.3%), and two cases combined Dandy-Walker deformity (6.7%). NCM is a rare disease, especially in adults. With the onset symptoms, the diagnosis is generally confirmed. For children with congenital giant nevus, there should be regular periodic surveys of the central nervous system (brain and spinal cord) MRI or cerebrospinal fluid examination to diagnosis. Active treatment should be undertaken to improve the prognosis. Copyright © 2018 Elsevier Inc. All rights reserved.

    The antimelanosic and antioxidative properties of a hot water extract prepared from the fruiting body of the edible mushroom (Flammulina velutipes) were evaluated by dietary supplementation in Kuruma shrimp (Marsupenaeus japonicus) for possible aquaculture application. The extract contained ergothioneine (ERT) at a level of 2.05 mg/mL. A commercial standard of l-ergothioneine (l-ERT) and the mushroom extract showed inhibitory activity against mushroom polyphenoloxidase (PPO). Feeding of the extract had no adverse effects on the immune systems of the shrimp under the present experimental conditions. Supplementation of the extract in the diet significantly suppressed PPO activities in the hemolymphs of the shrimp. Expression of the prophenoloxidase (proPO) gene decreased in the hemocyte of the Kuruma shrimp fed with the mushroom extract. Consequently, development of melanosis was significantly suppressed in the supplement fed shrimp during ice storage. Lipid oxidation was also effectively controlled in the supplement fed group throughout the storage period. In vitro experiments showed that l-ERT effectively inhibited the activation of proPO in the hemocyte lysate supernatant (HLS). The transcript of the proPO gene in the hemocyte showed lower expression in the l-ERT-treated HLS. It was concluded that dietary supplementation of the mushroom extract in shrimp could be a promising approach to control post mortem development of melanosis and lipid oxidation in shrimp muscles.

    Full Text Available Purpose: To report a case of primary acquired melanosis (PAM successfully treated with combined topical mitomycin C and interferon-α2b. Case Report: A 75-year-old man presented with an extensive unilateral pigmented lesion involving 360° of the bulbar conjunctiva, extending to the fornices and palpebral conjunctiva. Map biopsy confirmed PAM with local atypia. Treatment was initiated with mitomycin C 0.04% eye drops for two courses. Although the lesion markedly responded to the treatment, residual lesions justified further therapy. To avoid ocular surface toxicity induced by excessive mitomycin C exposure, interferon-α2b eye drops were started and continued for 6 months. The pigmented lesion almost completely disappeared and no significant complication or recurrence was observed for 24 months. Conclusion: Combination therapy using mitomycin C and interferon-α2b for PAM with atypia may be recommended as an effective treatment modality, avoiding the ocular surface toxicity due to excessive mitomycin C exposure.

    Full Text Available Backgrounds and Aims Melanosis coli (MC is a noninflammatory, benign, and reversible colonic disorder, but its detection rates in China are unclear. We therefore aimed to analyze the epidemiological characteristics of MC in China. Methods We assessed the detection rates, associated factors and concomitant diseases of MC in the patients who underwent colonoscopy at eight medical centers across five regions of China between January 2006 and October 2016. All data were procured from the electronic database established at each participating institutions. Results Among the 342,922 included cases, MC was detected in 6,090 cases (detection rate = 1.78%, 95% confidence interval, 1.73%–1.82% at a mean age of 60 years. The detection rate gradually increased yearly, and along with the increasing age regardless of gender, while a rapid increase presented in the patients ≥60 years of age (0.58% for ≤25 years, 1.22% for 25–59 years, and 3.19% for ≥60 years. The detection rate was higher in females than in males; however, the rate of per-year increase was higher in males than in females at age of ≥60 years, which was 1.85-fold of that in females. Among cancer, polyp, inflammation, and diverticula, polyp was the most common concomitant disease of MC and identified in 41.72% of MC patients. Conclusions MC detection rates were increased annually and elevated in older patients, particularly in male patients. Males in the elderly population of ≥60 years were most likely to have MC. Colonic polyp is the most common concomitant disease of MC.

Shrimp were treated with two different concentrations of sodium metabisulfite or 4-hexylresorcinol and subjected to the controlled atmosphere immediately after capture onboard ship or on arrival in port. Total volatile basic nitrogen, total viable counts, enterobacteria, lactic acid bacteria, and luminescent bacteria were determined, and black spot progression was evaluated. The combined effect of controlled atmosphere and melanosis inhibitors was used to delay black spot development as compared to the shrimp stored in ice alone. Storage under the controlled atmosphere without ice limited microbiological quality, namely, total viable counts, but enterobacterial growth was lower.

    At the faculties of dentistry in Chiang Mai, Thailand (CM), and Kuala Lumpur, Malaysia (KL), 234 and 233 consecutive out-patients were interviewed concerning tobacco and chewing habits and examined for the presence of oral melanin pigmentation. Tobacco was regularly used by 32% and 28% of the studied populations in CM and KL. Cigarette smoking was the predominant habit, but the chewing of betel and tea leaves (miang) and the smoking of banana leaf cigars (khi yo) was also registered. The genetically acquired pigmentation dominated. Although nearly all non-tobacco users in the Malay and Indian populations had oral melanin pigmentation, it was found that tobacco smokers had significantly more oral surfaces pigmented than non-tobacco users. Among Thais, the percentage of pigmented individuals was significantly higher among tobacco smokers. It was concluded that tobacco smoking stimulates oral melanocytes to a higher melanin production also in dark-skinned ethnic groups.

    Nevus sebaceus syndrome (SNS) is a constellation of nevus sebaceus with extracutaneous findings, including the ophthalmologic nervous, and musculoskeletal systems. Didymosis aplasticosebacea is a recently described entity consisting of aplasia cutis congenita and nevus sebaceus, implying twin spotting (didymosis). We describe a neonate with a nevus sebaceus on the scalp and a limbal dermoid on her left eye. Contiguous with the nevus sebaceus was a giant congenital melanocytic nevus and numerous areas of membranous aplasia cutis congenita. We propose the acronym SCALP (nevus sebaceus, central nervous system malformations, aplasia cutis congenita, limbal dermoid, pigmented nevus) to summarize the unique features of this case and review the two similar cases in the literature.

    The authors noted an unusual finding in the fallopian tubes of a 31-year-old woman who had received external and internal whole pelvis radiotherapy for squamous cell carcinoma of the cervix. Aggregates of macrophages containing pigment, identified in a subepithelial location, were reminiscent of melanosis coli, which is caused by abuse of anthracene-containing laxatives. Electron microscopic examination of the pigment revealed cytoplasmic material with the appearance of lipofuscin, identical to the pigment described in cases of colonic melanosis. After a careful study of possible etiologic agents, it was concluded that the pigment most likely resulted from cellular damage caused by radiotherapy. The authors are not aware of any other reported case of this entity, which will be called pigmentosis tubae

    Oral pigmentations (OPs) are often neglected, although a meticulous examination of the oral cavity is important not only in the diagnosis of oral melanoma, but also for the detection of important clinical findings that may indicate the presence of a systemic disease. OPs may be classified into two major groups on the basis of their clinical appearance: focal and diffuse pigmentations, even though this distinction may not appear so limpid in some cases. The former include amalgam tattoo, melanocytic nevi, melanoacanthoma and melanosis, while the latter include physiological/racial pigmentations, smoker's melanosis, drug-induced hyperpigmentations, postinflammatory hyperpigmentations and OPs associated with systemic diseases. We will discuss the most frequent OPs and the differential diagnosis with oral mucosal melanoma (OMM), underlining the most frequent lesions that need to undergo a bioptic examination and lesions that could be proposed for a sequential follow-up. © 2017 European Academy of Dermatology and Venereology.

    Full Text Available Facial melanoses (FM are a common presentation in Indian patients, causing cosmetic disfigurement with considerable psychological impact. Some of the well defined causes of FM include melasma, Riehl′s melanosis, Lichen planus pigmentosus, erythema dyschromicum perstans (EDP, erythrosis, and poikiloderma of Civatte. But there is considerable overlap in features amongst the clinical entities. Etiology in most of the causes is unknown, but some factors such as UV radiation in melasma, exposure to chemicals in EDP, exposure to allergens in Riehl′s melanosis are implicated. Diagnosis is generally based on clinical features. The treatment of FM includes removal of aggravating factors, vigorous photoprotection, and some form of active pigment reduction either with topical agents or physical modes of treatment. Topical agents include hydroquinone (HQ, which is the most commonly used agent, often in combination with retinoic acid, corticosteroids, azelaic acid, kojic acid, and glycolic acid. Chemical peels are important modalities of physical therapy, other forms include lasers and dermabrasion.

    Full Text Available Phacomatosis cesioflammea is a rare condition defined by the simultaneous presence of both vascular and pigmentary nevus in the same patient. We report a case of a 4-year-old Indian female child who presented with diffuse dermal melanosis on the upper shoulders, upper anterior chest and lower back and extending to involve both sides of the arms and forearms, generalized port-wine stain on the back, shoulders and both upper limbs with sparing of the right palm. At places, the two types of lesions were superimposed on each other and were also present discretely on the back, but in close proximity to each other. There was the presence of melanosis bulbi on the right side of the eye. She was otherwise normal. She was clinically diagnosed as a case of phacomatosis pigmentovascularis cesioflammea. The nonallelic twin spotting phenomenon has been proposed in the pathogenesis of this disorder.

    Full Text Available Nevus of Ota (oculodermal melanosis is a dermal melanocytic hamartoma with bluish hyperpigmentation along the first and second branches of the trigeminal nerve. Extracutaneous involvement, especially ocular, has been reported. A 45-year-old male presented with malignant melanoma of the left orbit in association with nevus of Ota. Being locally invasive, a modified exenteration with frontal flap repair was done on left eye. Adjuvant chemotherapy was given after wound healing. All pigmented lesions of the eye require close monitoring to help in the early diagnosis. Since malignant transformation has been reported in oculodermal melanosis, close follow-up and patient education will facilitate early diagnosis and prompt management. This case is reported for its rarity and unusual presentation.

    2016-06-01

    Melanoma is a malignancy most commonly arising from the skin; therefore, primary melanoma characteristics are usually the first cutaneous manifestations of melanoma. Cutaneous metastases, which can occur locally or diffusely, are important to detect in a timely manner as treatments for advanced melanoma that impact survival are now available. Melanoma can be associated with local or diffuse pigmentation changes, including depigmentation associated with the leukodermas and hyperpigmentation associated with diffuse melanosis cutis. The leukodermas occur frequently, illustrate the immunogenic nature of melanoma, and may impact prognosis. Paraneoplastic syndromes in association with melanoma are rare, though can occur.

    1978-05-01

    In accordance with microscopic and clinical criteria established for superficial melanomas of the skin (superficial spreading melanoma, lentigo maligna melanoma, acral-lentiginous melanoma), three oral lesions have been evaluated. The literature on oral melanomas has also been reviewed, with special attention given to those cases that had pre-existing melanosis. One patient with a diagnosis of superficial spreading melanoma eventually died of his untreated lesion 11 years after its first appearance. Two patients had lesions diagnosed as acral-lentiginous melanoma (a group which also includes volar and subungual melanomas) that exhibited aggressive, recurrent behavior. These lesions had microsocpic features similar to lentigo maligna melanoma but did not behave in a manner consistent with that diagnosis. Electron microscopic study of one acral-lentiginous melanoma demonstrated malenosomes and premelanosomes that were like those seen in normal melanocytes and nevus cells. The superficial or radial growth phase of many oral melanomas has apparently gone unrecognized. Melanosis has been reported to be a common feature of invasive oral melanomas but has not generally been related to the natural history of these lesions. Oral lesions with a prolonged intra-epithelial or radial growth phase would be expected to have a better prognosis than nodular melanomas, but meaningful survival data are not available because of the infrequency with which oral melanomas have been subclassified.

    The combined effects of freezing and modified atmosphere packaging (MAP) (100% N2 and 50% N2+50% CO2) on some quality characteristics of Giant Red Shrimp (GRS) (Aristaeomorpha foliacea) was studied during 12-month storage. In particular, the quality characteristics determined proximal and gas compositions, melanosis scores, pH, total volatile basic-nitrogen (TVB-N), thiobarbituric acid (TBA) as well as free amino acid (FAA). In addition, the emergent data were compared to those subject to vacuum packaging as well as conventional preservative method of sulphite treatment (SUL). Most determined qualities exhibited quantitative differences with storage. By comparisons, while pH and TVB-N statistically varied between treatments (P<0.05) and TBA that ranged between ∼0.15 and 0.30 mg MDA/kg appeared least at end of storage for 100% N2 treated-group, the latter having decreased melanosis scores showed such treatments with high promise to keep the colour of GRS sample hence, potential replacement for SUL group. By comparisons also, while some individual FAA values showed increases especially at the 100% N2-treated group, the total FAAs statistically differed with storage (P<0.05). The combination of freezing and MAP treatments as preservative treatment method shows high promise to influence some quality characteristics of GRS samples of this study.

    2017-04-19

    Melanocytes are found throughout the oral mucosa but usually go unnoticed because of their relatively low level of pigment production. When focally or generally active in pigment production or proliferation they may be responsible for several affections in the oral mucosae ranging from physiologic pigmentation, systemic diseases to malignant neoplasms. The diagnosis of oral pigmentations (OP) is usually challenging for the physician, but a careful examination of the oral cavity may reveal the first manifestation of underlying systemic diseases. Therefore, a full medical history (including drug assumption and smoking) together with a general dermatological examination are mandatory and represent the first approach to OPs. When the diagnosis cannot be reached clinically with enough certainty, a biopsy for histological examination is needed, also in order to exclude possible life threatening conditions such as melanoma. Dermoscopy is another reliable diagnostic tool to make a differential diagnosis between melanocytic lesions and other conditions and then to manage the follow-up of patients. Few papers on the subject have been published in the dermatological literature and the oral cavity is often poorly investigated during routine dermatological examinations. We therefore decided to perform a review of benign OPs, classifying them into diffuse (physiological/racial pigmentations, smoker's melanosis, drug induced hyperpigmentations, post-inflammatory hyperpigmentations, black hairy tongue, OPs associated to systemic diseases) and localized (amalgam tattoo, melanocytic nevi, melanoacanthoma, melanosis) lesions.

    Full Text Available Prediction of bacterial growth, survival or reduction in food matrices is needed for microbiological risk assessment. The survival of Salmonella Typhimurium on surfaces of raw shrimps at low temperature was studied, in the presence of sodium metabisulfite which is often used to prevent melanosis. The growth and/or reduction rates were quantified using DMFit software with Baranyi model and or linear model. The result showed that without sodium metabisulfite (control, when the initial level was high (105 CFU/ml, S. Typhimurium grew with a lag phase of 51.99±7.46 h and a growth rate of 0.01±0.002 log CFU.ml-1.h-1 on raw shrimps during storage at 8±2°C. When 1.5% (w/w sodium metabisulfite, a maximum level that often used to prevent melanosis, was added under the same condition, the number of S. Typhimurium was reduced for 5 log CFU/ml after 5 days, with a reduction rate of -0.03±0.001 log CFU.ml-1.h-1. This study indicated that Baranyi model can be used to predict the growth of S. Typhimurium on raw shrimp at low temperature, when sodium metabisulfite is absent. However, when sodium metabisulfite is present, at least 0.4% as found in this study, the reduction of S. Typhimurium can be predicted using a simple linear model.

    Melanomas of the penis are rare tumors of poor prognosis. Six cases of melanoma of the penis, followed between 1975 and 2002, were retrospectively reviewed. We collected the data on epidemiological, clinical and pathologic factors, treatment and follow-up. The mean age was 44 years. The time to diagnosis was 2 years. Two patients had general predisposing factors for melanoma, and 3 patients local predisposing factors. Two patients had partial penectomy and 4 patients had conservative excision. One patient had local recurrence, and another had metastatic course resulting in death. Five patients out of 6 were alive and disease free at time of the study, with a 24 month follow-up. The identified risk factors for the development of penile melanoma are melanosis and pre-existing nevus. Delayed diagnosis explains the usually bad prognosis. Classical surgical treatment used to be radical, but recently, conservative surgery has been proposed. For an early diagnosis, genital melanosis requires surgical excision, when technically feasible, and any atypical lesion of the penis should be submitted to a biopsy.

    Sulfur-containing compounds heated under alkaline condition (pH 10) were determined for inhibitory activity toward polyphenol oxidase (PPO) from Pacific white shrimp (Litopenaeus vannamei) and for antioxidative activity. Cysteine and glutathione (GSH) (20 mM) heated at 100 degrees C at pH 10 strongly inhibited PPO activity. Heated alkaline cysteine showed the greater 2,2-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) and 2,2-diphenyl-1-picryl hydrazyl (DPPH) radical scavenging activity, copper-chelating activity and reducing power than cysteine and glucose-cysteine Maillard reaction products (P alkaline cysteine at different concentrations (0, 20, and 100 mM) on the quality changes of Pacific white shrimp during iced storage was investigated. Shrimp treated with 100 mM heated alkaline cysteine had the lowest melanosis score, thiobarbituric acid-reactive substances (TBARS) value and total viable count (TVC), compared with those without treatment and treated with 20 mM heated alkaline cysteine, throughout the storage of 12 d (P alkaline cysteine can be used as a novel additive to retard melanosis and extend the quality of postmortem shrimp.

    Beck-Mannagetta, J; Hutarew, G

    2012-09-01

    The oral mucosa contains melanocytes, even though one might not suspect this when examining white subjects. Drug-induced pigmentation is usually irregularly distributed over the oral mucosa; typical causes are contraceptives and tetracyclines. Localized traumatic pigmentation can be due to injuries contaminated by foreign material (dust). Not infrequently an amalgam tattoo can be seen, caused by introduction of amalgam during dental treatment with rotating instruments. Focal melanosis is harmless. Neoplastic pigmentation is rare. Melanotic nevi are small with indistinct borders. Malignant melanoma occurs predominantly on the maxilla or hard palate. Frequently it has already metastasized by the time of diagnosis. Verification by biopsy is essential if a lesion has suddenly appeared, is extensive, elevated, with irregular pigmentation and has no obvious cause.

    2016-02-01

    In ethnic skin, traditional skin resurfacing procedures such as dermabrasion, chemical peels, and laser therapy can be effective but can also be associated with prolonged recovery and risk of complications. These complications can include a higher risk of dyspigmentation and scarring, and unsatisfactory clinical outcomes. Microneedling is an evolving treatment technique for an expanding number of dermatologic conditions. Microneedling may offer a more advantageous safety profile, particularly in the skin-of-color population (Fitzpatrick skin types IV-VI), compared with more conventional resurfacing modalities. Thus far, it has been shown to be effective for a number of dermatologic conditions in this population, including scarring, melasma, melanosis, skin rejuvenation, acne vulgaris, and primary hyperhidrosis. This article aims to provide a comprehensive review of the literature regarding the efficacy and safety of microneedling in skin of color. Copyright © 2015 American Academy of Dermatology, Inc.

    2014-10-01

    Full Text Available In this article we give an update on recent findings regarding molecular pathology in cutaneous melanocytic tumours. The focus lies on use of genetics in the diagnosis of distinct subtypes of spitzoid tumours that are often characterized by specific phenotypic-genotypic alterations that can frequently be recognized by adequate histological examination. Typical illustrating cases are given in order to increase recognition of these lesions in daily dermatopathology practice. New molecular findings in the pathogenesis of congenital melanocytic tumours and neurocutaneous melanosis are reviewed. In addition use of mutation analysis in the differential diagnosis of melanoma metastasis is discussed. Finally application of mutation analysis in targeted therapy in advanced melanoma with advantages of new techniques such as next generation sequencing is described.

    Malignant melanoma of the conjunctiva is a rare tumor with incidence of 0.5 cases/year per million population. It may also occur as de novo, as on the basis of preexisting melanocytic lesions (nevus or freckle) or most often from the so-called primary acquired melanosis of the conjuctiva (PAM). It metastasizes mainly lymphogenic and hematogenous. The size of the primary tumor lesion, histopathological findings and absolute tumor thickness are essential for unfavorable prognosis. Conjunctival auto transplantation from the other eye is modern and innovative, but also a seldomly feasible method of reconstruction after conjunctival excision of tumors in this area. We present a rare case of a 75-year-old patient with epithelioid cell malignant melanoma of the bulbar conjunctiva of the right eye, which de novo occurred, successfully treated by excision of the primary tumor and subsequent reconstruction by conjunctival auto transplant from the other eye. A very good therapeutic and aesthetic result was achieved.

Given their ubiquitous presentation, it is sometimes difficult to differentiate among self-limiting, noninfectious, pustular dermatosis such as erythema toxicum neonatorum, transient neonatal pustular melanosis, miliaria pustulosa, etc., and potentially life threatening infections such as herpes simplex virus and varicella zoster virus infections. This review article tries to address the chronological, clinical, morphological, and histological differences among the various pustular eruptions in a newborn, in order to make it easier for a practicing dermatologist to diagnose and treat these similar looking but different entities of pustulation with a clear demarcation between the physiological benign pustular rashes and the infectious pustular lesions.

    Full Text Available Ashy dermatosis, also known as erythema dyschromicum perstans, is an idiopathic dermal melanosis of unknown etiology. We here describe an unusual case of 63-year-old Caucasian male with ashy dermatosis and skin lesion of lichen pigmentosus-like. No treatment was tried because the lesions were totally asymptomatic. After a control, three months later, all lesions had cleared up. This case is of interest because it proves the existence of ashy dermatosis with clinical aspect lichen planus pigmentosus-like. This is the first case in the literature of lichen planus pigmentosuslike ashy dermatosis confirming the view that ashy dermatosis is a variant of lichen planus without the typically band-like infiltrate and Max Joseph spaces.

    Arsenic is a toxic metalloid of global concern. It usually originates geogenically but can be intensified by human activities such as applications of pesticides and wood preservatives, mining and smelting operations, and coal combustion. Arsenic-contaminated food is a widespread problem worldwide. Data derived from population-based studies, clinical case series, and case reports relating to ingestion of inorganic arsenic in drinking water, medications, or contaminated food or beverages show the capacity of arsenate and arsenite to adversely affect multiple organ systems. Chronic arsenic poisoning can cause serious health effects including cancers, melanosis (hyperpigmentation or dark spots, and hypopigmentation or white spots), hyperkeratosis (hardened skin), restrictive lung disease, peripheral vascular disease (blackfoot disease), gangrene, diabetes mellitus, hypertension, and ischemic heart disease.

    Cutaneous lesions are commonly seen in the newborn period and exhibit inconsistency from the skin lesions of an adult. The present study was carried out with an aim to determine the frequency of physiologic and pathologic cutaneous findings in newborns. Typically, 1234 newborns were included in this study. A questionnaire about maternal gestational history, maternal and family history was issued to the parents of each newborn. The presence of cutaneous lesions was recorded. Overall, 642 (52%) of the newborns were male and 592 (48%) were female. Typically, 831 newborns (67.3%) had at least one cutaneous lesion. The prevalence of genital hyperpigmentation and milia was significantly higher in males. In premature newborns, the pervasiveness of cutis marmorata and genital hyperpigmentation was found to be significantly higher. Caput succedaneum, transient neonatal pustular melanosis and cyanosis appeared predominantly in vaginally born infants. Erythema toxicum neonatorum was seen in infants, who were born by cesarean section. The predominance of Mongolian spots and erythema toxicum neonatorum were significantly higher in the newborns of the multiparous mothers; however, caput succedaneum was significantly higher in newborns of the primiparous mothers. A number of studies about neonatal dermatoses have been carried out involving different methods in various countries. We consider that our study may be useful in literature, as it has been carried out involving large number of maternal parameters.

    Arsenic (As) poisoning has become a worldwide public health concern. The skin is quite sensitive to As and skin lesions are the most common and earliest nonmalignant effects associated to chronic As exposure. In 2005-2007, a survey was carried out on surface and groundwater arsenic contamination and relationships between As exposure via the drinking water and related adverse health effects (melanosis and keratosis) on villagers resides on the banks of Manchar lake, southern part of Sindh, Pakistan. We screened the population from arsenic-affected villages, 61 to 73% population were identified patients suffering from chronic arsenic toxicity. The effects of As toxicity via drinking water were estimated by biological samples (scalp hair and blood) of adults (males and females), have or have not skin problem (n = 187). The referent samples of both genders were also collected from the areas having low level of As ( 2 = 0.852 and 0.718) as compared to non-diseased subjects (R 2 = 0.573 and 0.351), respectively

    2011-02-01

    Pityriasis alba (PA) is a localized hypopigmented disorder of childhood with many existing clinical variants. It is more often detected in individuals with a darker complexion but may occur in individuals of all skin types. Atopy, xerosis, and mineral deficiencies are potential risk factors. Sun exposure exacerbates the contrast between normal and lesional skin, making lesions more visible and patients more likely to seek medical attention. Poor cutaneous hydration appears to be a common theme for most risk factors and may help elucidate the pathogenesis of this disorder. The end result of this mechanism is inappropriate melanosis manifesting as hypopigmentation. It must be differentiated from other disorders of hypopigmentation, such as pityriasis versicolor alba, vitiligo, nevus depigmentosus, and nevus anemicus. Alleviation of the various risk factors via patient education on proper skin care and hygiene, use of lubricants and emollients, topical corticosteroid therapy in the presence of inflammation, and the novel administration of topical anti-inflammatory drugs such as calcineurin inhibitors can play a crucial role in promoting remission or resolution.

    To examine the relative prevalence, types, and clinical features of pigmented lesions of the oral mucosa in 1275 patients attending a university hospital for dental care. Patients attending dental clinics at The University of Jordan Hospital over a 1-year period were examined for the presence of oral pigmentations. Histopathological examination was performed on focally pigmented lesions with a suspicious or uncertain clinical diagnosis. A total of 386 (30.2%) patients were found to have oral pigmentations. Of these, racial pigmentation (39.9%) and smokers' melanosis (32.9%) were the most common causes of oral pigmentations. Other causes included amalgam tattoo (18.9%), focal melanotic macules (5.7%), postinflammatory pigmentation (1.6%), pigmentation due to medications or systemic disease (0.52%), heavy metal deposits (0.26%), and oral nevus (0.26%). Gingivae and buccal mucosae were the most common sites for oral pigmentations. Pigmentations of the oral mucosa are common. Gingivae and buccal mucosae are the most common sites for oral pigmentations.

    Full Text Available Aim. To report a case of bilateral Sturge-Weber and Phakomatosis pigmentovascularis with secondary glaucoma in a child. Method. Case report. Results. A 4-year-old male child was referred to us for control of intraocular pressure (IOP. Sleeping IOP was 36 mm Hg in right eye and 28 mm Hg in the left eye. The sclera of both the eyes showed bluish black pigmentation—melanosis bulbi. Fundus examination of both eyes showed diffuse choroidal hemangiomas with glaucomatous cupping. Nevus flammeus was present on both sides of face along all the 3 divisions of trigeminal nerve with overlying hypertrophy of skin and on left forearm. Nevus fuscocaeruleus was present on upper trunk. All skin lesions were present since birth and were stationary in nature. CT scan of head revealed left-sided cerebral atrophy. Intraocular pressure was controlled after treatment with topical antiglaucoma medications. Pulsed Dye Laser has been advised by dermatologist for skin lesions. Patient has been advised for regular follow-up. Conclusion. The two overlapping dermatological disorders and their association with glaucoma are a rare entity. Management should be targeted both for dermatological and eye conditions.

    Full Text Available Constipation is one of themost common chronic gastrointestinal problems. The estimated incidence of constipation in the United States is3% to 19% in general population.1,2 Patientswith head injuries, spinal cord injuries, pelvic fractures, lower extremity fractures ormultiple traumas require a long-term bed rest, during which the incidence of constipation reached as high as 50%.3,4 Constipation always brings inconvenience and tremendous suffering to patientsand strongly influences the recovery from primary disease. Irritants or lubricants can relieve the symptoms, but long-term application of them may lead to side effects like melanosis coli5 and cathartic colon6. The absorption of fat soluble vitamins is also affected.7 Polyethylene glycol 4000 (trade name: Forlax®, a long chain polymer with a high molecular weight, can conjugate withwater molecule through hydrogen bond to increase the water content and volume of stools, thereby, facilitate bowelmovement and defecation.8,9 It is neither absorbed nor metabolized in the digestive tract, hence it is highly safe and well tolerable. Thus, long-term medication of polyethylene glycol 4000 is conducive to the reconstruction of normal defecation pattern. Therefore, polyethylene glycol 4000 is now being widely used as the mainstay adult chronic functional constipation management.10,11 The aim of this study was to verify the efficacy and safety of polyethylene glycol 4000 on adult functional constipation of posttraumatic bedridden patients.

    The diagnostic yield in open access endoscopy has been evaluated which generally support the effectiveness and efficiency of open access endoscopy. With a few exceptions, diagnostic yield studies have not been performed in open access endoscopy for more specific conditions. Therefore, we conducted a study to determine the efficiency of open access endoscopy in the detection of microscopic colitis as compared to traditional referral via a gastroenterologist. A retrospective search of the pathology database at the University of Missouri for specimens from a local open access endoscopy center was conducted via SNOMED code using the terms: "microscopic", "lymphocytic", "collagenous", "spirochetosis", "focal active colitis", "melanosis coli" and "histopathologic" in the diagnosis line for the time period between January 1, 2004 and May 25, 2006. Specimens and colonoscopy reports were reviewed by a single pathologist. Of 266 consecutive patients with chronic diarrhea and normal colonoscopies, the number of patients with microscopic disease are as follows: Lymphocytic colitis (n = 12, 4.5%), collagenous colitis (n = 17, 6.4%), focal active colitis (n = 15, 5.6%), and spirochetosis (n = 2, 0.4%). The diagnostic yield of microscopic colitis in this study of an open access endoscopy center does not differ significantly from that seen in major medical centers. In terms of diagnostic yield, open access endoscopy appears to be as effective in diagnosing microscopic colitis.

    A 30-year-old woman presented with congenital hyperpigmented plaques and multiple tumoral lesions. Her left leg was hypertrophic, although the bones were normal. Dermatological examination revealed hyperpigmented macules and plaques with hair on the legs, abdominal and lumbar areas (covering > 60% of the total body surface) and multiple naevi on the face, arms, back and chest. Multiple soft masses of various sizes, some of which colocalized with hyperpigmented plaques, were seen on the trunk and legs. Malignant melanoma was excluded by histopathological examinations of multiple biopsy specimens obtained from the pigmented lesions. Histopathological examination of one of the soft masses showed that it was a lipoma. Cranial magnetic resonance imaging and computed tomography scans showed an enlarged fourth ventricule and vermis hypoplasia (Dandy-Walker malformation; DWM). Neurocutaneous melanosis is a rare combined abnormality of the skin and central nervous system. A few case reports relating to the coexistence of giant congenital melanocytic naevus, lipomatosis and hemihypertrophy have been published in the literature. We report this very rare case of giant melanocytic naevus with lipomatosis, hemihypertrophy of the leg, and DWM.

    The presence of any age-related differences in gingival pigmentation associated with smoking, particularly in a young population, remains to be fully investigated. The purpose of this study was to determine the age-related differences in smoking gingival pigmentation. Gingival pigmentation was analyzed using the gingival melanosis record (GMR) and Hedin's classification with frontal oral photographs taken at 16 dental offices in Japan. Participants were categorized into 10-year age groups, and their baseline photographs were compared. In addition, to evaluate the effect of smoking cessation on gingival pigmentation, subjects were divided into a former smoker group (stopped smoking) and current smoker group. A total of 259 patients 19 to 79 years of age were analyzed. People in their 30s showed the most widespread gingival pigmentation. In addition, subjects in their 20s showed a weak effect of smoking cessation on gingival pigmentation. These findings suggested that the gingival pigmentation induced by smoking was more remarkable in young people than in middle-aged people. This information may be useful for anti-smoking education, especially among young populations with a high affinity for smoking.

    Chemical and microbiological deteriorations are principal causes of quality loss of fish and fish products during handling, processing, and storage. Development of rancid odor and unpleasant flavor, changes of color and texture as well as lowering nutritional value in fish can be prevented by appropriate use of additives. Due to the potential health hazards of synthetic additives, natural products, especially antioxidants and antimicrobial agents, have been intensively examined as safe alternatives to synthetic compounds. Polyphenols (PP) are the natural antioxidants prevalent in fruits, vegetables, beverages (tea, wine, juices), plants, seaweeds, and some herbs and show antioxidative and antimicrobial activities in different fish and fish products. The use of phenolic compounds also appears to be a good alternative for sulphiting agent for retarding melanosis in crustaceans. Phenolic compounds have also been successfully employed as the processing aid for texture modification of fish mince and surimi. Thus, plant polyphenolic compounds can serve as potential additives for preventing quality deterioration or to retain the quality of fish and fish products.

It can arise in previously unblemished and unpigmented regions (approximately 10% of cases, from a preexisting nevus (approximately 20% of cases, or from the flat, spreading pigmentation of primary acquired melanosis with atypia (60–70% of cases, actually called conjunctival melanocytic intraepithelial neoplasia (C-MIN with atypia (histopathologically more accurately term. Purpose: The authors describe an extremely rare case of malignant conjunctival melanoma, with a long evolution, in a young black woman. Results: Until now the patient has not shown any sign of relapse of this melanoma, after local excision.Conclusion: Conjunctival melanoma is a condition of concern because of its rarity and lethal potential. Advances in the understanding and management of this neoplasm have markedly reduced the mortality and possibly the morbidity associated with this malignancy. We observe that there are some cases of conjunctival melanoma that might be cured with only a local excision with posterior cryotherapy without more aggressive methods. The practice of narrative medicine brings new possibilities in the diagnosis and collection of classical history.

    Ocular melanoma is the second most common type of melanoma after cutaneous and the most common primary intraocular malignant tumor in adults. Large majority of ocular melanomas originate from uvea, while conjunctival melanomas are far less frequent. Incidence of uveal melanoma has remained stable over last three decades. Diagnosis is in most cases established by clinical examination with great accuracy. Local treatment of uveal melanoma has improved, with increased use of conservative methods and preservation of the eye, but survival rates have remained unchanged. Recent advances in cytogenetics and genetics enhanced prognostication and enabled to determine tumors with high metastatic potential. However, due to lack of effective systemic therapy, prognosis of patients with metastasis remains poor and metastatic disease remains the leading cause of death among patients with uveal melanoma. Conjunctival melanoma is rare, but its incidence is increasing. It mostly occurs among white adults. In majority of cases it originates from preceding primary acquired melanosis. Current standard treatment for conjunctival melanoma is wide local excision with adjuvant therapy, including brachytherapy, cryotherapy and topical application of chemotherapeutic agent. Rarity of this tumor limits conduction of controlled trials to define the best treatment modality. As well as for uveal melanoma, prognosis of patients with metastasis is poor because there is no effective systemic therapy. Better understanding of underlying genetic and molecular abnormalities implicated in development and progression of ocular melanomas provides a great opportunity for development of targeted therapy, which will hopefully improve prognosis of patients with metastatic disease.

    The radiotherapy efficiency is still undervalued in the therapeutic taking charge of the malignant melanoma. Our series with its heterogeneity has authorized an only mono factorial analysis. The data in literature and our personal experience give a better efficiency of the strong unitary doses in term of local control. The accuracy of irradiation must allow to reduce the importance of after-effects that can be necessary to the local control and then to the survival. for the future, an increasing of of the applied unitary doses, by taking into account the localisation, the tumoral volume and the therapeutic objective, would allow to improve the efficiency of this treatment. In The particular indication of inoperable Dubreuilh melanosis, it could be an alternative to the surgery. The results of a complementary radiotherapy, after a radical surgery of secondary localisation are very encouraging. Its contribution in adjuvant treatment of recurrence or primitive lesions with high risks would deserve to be evaluated in the frame of well defined and randomized tests. (N.C.)

    Full Text Available Sodium metabisulfite is the main additive used in the prevention of melanosis in shrimp; however, it has currently been employed with great variation in concentration by producers. Thus, the aim of the present study was to determine the correlation between the concentration of the sodium metabisulfite solution and immersion time of the whole shrimp to obtain the concentration of sulfur dioxide (SO2 in the edible muscle of farmed shrimp (Litopenaeus vannamei in accordance with the limit established by law. For this, solutions of sodium metabisulfite at different concentrations (1%, 2 %, 3 %, 4% and 5% were prepared and samples of L. vannamei shrimp (100g were immersed during 10, 20 or 30 minutes at temperature of 7°C. For all treatment assayed the concentration of SO2 was determined in the edible muscle of farmed shrimp (L. vannamei. The results show that for the conditions used in this study, the correlations were linear, with significant increase (P<0.05 in the SO2 concentration in the edible muscle of shrimps both increasing sodium metabisulfite concentration as increasing immersion times, suggesting the immersion of shrimps in a 3% solution for a time of 13 minutes in order to obtain SO2 concentration of 100ppm in its edible muscle in accordance with Brazilian legislation

    Full Text Available Background: Black spots are a major problem in commercial shrimp species and can have negative effects on shrimps' appearance, quality, shelf life, economic value, and product acceptance by consumers. This study was conducted to investigate the effect of orange peel extract on chemical and sensory qualities as well as black spots on Litopenaeus vannamei species of white farmed shrimp. Methods: Samples included treated shrimps at concentration of 150 g, orange peel extract for 30 minutes, and control shrimps. After storage for 10 days at 1 ± 4 °C, the samples’ chemical and sensory evaluations were performed with an interval of 5 days. Results: pH factors, peroxide value, and total volatile network (TVN of treated samples were significantly lower compared to those of the control samples (P < 0.05. There was no significant difference in the moisture content. Black spots did not appear in the treated sample until the end of refrigerated storage, but melanosis appeared in control shrimp 5 days after storage. Conclusion: The results showed that because of having antioxidant and antimicrobial activity, orange peel extract improved shrimps' chemical and sensory qualities and reduced their black spots in the refrigerator temperature.

  1. Colorectal adenomas produce lysozyme.

    Rubio, C A

    2003-01-01

    Lysozyme is an innate non-immunologic antibacterial enzyme produced by the Paneth cells of the upper intestinal tract. Lysozyme is not normally secreted in the lower intestinal tract. Previous reports indicate, however, that lysozyme may be secreted by colorectal neoplasias. The aim was to audit lysozyme expression in colorectal diseases including neoplasias. For that purpose, sections were stained with lysozyme (Muramidase), Ki67 (MIB1) and CD 68. Intense lysozyme overexpression (+++) was compared among 177 colorectal tissues: 35 having normal mucosa, 20 regenerative mucosa in inflammatory bowel disease (IBD), 2 inflammatory polyps, 3 collagenous colitis, 2 melanosis coli, 21 hyperplastic polyps, 42 tubular adenomas, 9 serrated adenomas, 30 villous adenomas and 13 invasive carcinomas. Intense lysozyme overexpression (+++) was found in 9.5% of the hyperplastic polyps, in 97.6% of the tubular adenomas, in 88.9% of the serrated adenomas, in 93.3% of the villous adenomas, in 76.9% of the carcinomas, but in none of the other tissues investigated. Neoplastic colorectal cells may acquire the capacity to produce lysozyme. The presence of that enzyme may not be a haphazard, capricious event in mutated colorectal epithelial cells but part of a more elaborate molecular behavior, not necessarily antibacterial. Recently, it was demonstrated that patients having lysozyme-secreting breast carcinomas were associated with a favorable prognosis. Whether lysozyme expression has any bearing on the biological behavior of colorectal carcinomas remains to be elucidated. Lysozyme overexpression (+++) also occurred in 2 of the 21 hyperplastic polyps, suggesting that intense lysozyme production might herald a possible dysplastic evolution in some hyperplastic polyps.

    In Pakistan cirrhosis has reached alarming proportions due to spread of HCV and HBV viruses. Some of the oral manifestations of cirrhosis have been found to exhibit geographically variability. There is no research available on the oral health of these patients in Pakistan and their specific oral problems are not known. This study examined a cohort of cirrhotic patients admitted at Shaikh Zayed hospital Lahore to assess their oral health status and needs. Materials and methods: Thirty consecutive patients admitted with diagnosis of cirrhosis were examined for oral health status. Extra oral examination included any visible lesions or abnormalities on the face, head or neck region, lymph node enlargement and TMJ dysfunction. Intra oral examination included measurement of caries (DMFT) and periodontal disease level (CPITN), oral mucosal lesions, prosthetic status and prosthetic needs of the patients. All findings were recorded on the standard WHO oral health survey form. The oral health of this cohort was poor compared to the general population. Xerostomia (20%), papillary atrophy (100%), oral Melanosis (90%), petechieal hemorrhages (26%) and glossitis (53%) were found prevalent in the sample. Two females had oral lichen planus and one of the patients had oral ulceration. DMFT score (Mean=5.7) was not different from national average (Mean=8.02). Periodontal disease was more severe than general population. Less than 21% of the sample wore prostheses and over 50% needed one. TMJ dysfunction was common but fewer patient complained of the condition that the number of patients with clinical signs. Conclusions: Oral health of cirrhotic population is worse than general population and they have significant oral health needs. Further research is required to investigate this relationship. Effective oral health education of patients and physicians is required to reduce the burden of oral disease thus improving quality of life for these patients. (author)

    Full Text Available Background: Periorbital dermatoses are very common dermatological disorders which pose a diagnostic and therapeutic challenge for the treating dermatologist due to the similarity of symptoms in this area. Aims: To study the spectrum of periorbital dermatoses and to assess the association of systemic diseases with periorbital dermatoses. Methods: This was a hospital based descriptive study done on 250 consecutive patients irrespective of their age and sex who attended the Dermatology out patient department (OPD, with dermatological conditions pertaining to the periorbital area over a period of 2 years from October 2010 to September 2012. Results: The most common dermatological conditions seen in the periorbital region were benign and malignant skin tumors observed in 63 (25.2% cases, followed by the disorders of pigmentation in 51 (20.4% and eczema in 44 cases (17.6%, infections in 33 (13.2% cases and nevoid conditions in 26 (10.4% cases. Certain periorbital dermatoses were significantly more in females than in males in the present study like skin tags, connective tissue diseases, and periorbital melanosis (POM. Some periorbital dermatoses were significantly more common in older age group such as seborrheic keratoses, skin tags and airborne contact dermatitis whereas infections, syringomas, allergic contact dermatitis and atopic dermatitis were more prevalent in younger age group. Syringomas and POM were more common in middle-aged women. Conclusions: The most common dermatological condition seen in the periorbital region in this study are benign skin tumors (keratosis and skin tags, followed by the disorders of pigmentation and eczema, infections and nevoid conditions.

    Highlights: {yields} Influence of cyclic stretch on melanogenetic paracrine cytokines was investigated. {yields} Keratinocyte-derived endothelin-1 was upregulated with cyclic stretch. {yields} Degree of upregulation increases dose-dependently. {yields} This upregulation possibly plays a role in the pathogenesis of pigmented disorders. -- Abstract: The aim of this study was to investigate the possible pathological relation between mechanical stress and hyperpigmentation. We did this by investigating the influence of cyclic stretch on the expression of keratinocyte- and fibroblast-derived melanogenetic paracrine cytokines in vitro. Using primary human keratinocytes and fibroblasts, alterations of mRNA expression of melanogenetic paracrine cytokines due to cyclic stretch were investigated using a real-time polymerase chain reaction (PCR). The cytokines included basic fibroblast growth factor (bFGF), stem cell factor (SCF), granulocyte/macrophage colony-stimulating factor, interleukin-1{alpha}, and endothelin-1 (ET-1) for keratinocytes and bFGF, SCF, and hepatocyte growth factor for fibroblasts. The dose dependence of keratinocyte-derived ET-1 upregulation was further investigated using real-time PCR and an enzyme-linked immunosorbent assay. We also investigated the effects of cyclic stretch on the proliferation and differentiation of keratinocytes. Among the melanogenetic paracrine cytokines investigated, keratinocyte-derived ET-1 was consistently upregulated in all four cell lines. The degree of upregulation increased with the degree of the length and frequency of the stretch; in contrast, cell number and differentiation markers showed no obvious alterations with cyclic stretch. Keratinocyte-derived ET-1 upregulation possibly plays a significant role in the pathogenesis of pigmented disorders, such as friction melanosis, caused by mechanical stress.

    Melanoma of the eye can involve the uveal tract with iris, ciliary body, or choroid involvement or it can involve the conjunctiva, eyelid, or orbit. Uveal involvement with choroidal melanoma is the most common, found in light complexion Caucasians with an age-adjusted incidence of 4.3 per million persons. Early detection of uveal melanoma is critical. The ABCDEF guide helps to differentiate iris nevus from iris melanoma. The letters represent: A, age young (≤40 years); B, blood in anterior chamber; C, clock hour of mass inferiorly; D, diffuse configuration; E, ectropion; and F, feathery margins. The mnemonic of TFSOM-UHHD (To Find Small Ocular Melanoma-Using Helpful Hints Daily) helps to differentiate choroidal nevus from small melanoma and represents: T, thickness over 2 mm; F, fluid; S, symptoms; O, orange pigment; M, margin within 3 mm of the optic disc; UH, ultrasound hollow; H, halo absent; and D, drusen absent. Patients with 3 or more of these factors are likely to have melanoma. These key clinical features help to identify small melanoma at a time when therapy could be life-saving. Conjunctival melanoma usually arises from primary acquired melanosis, a flat pigmentation that can lead to melanoma. Wide excision using no touch strategy is important to tumor control. Ocular examination is advised annually for all persons for detection of refractive error, cataract, glaucoma, and other conditions, but also for the detection of asymptomatic malignancies like melanoma. One at a time, we have uncovered the secrets of ocular melanoma and we forge ahead with the goal to solve the riddle of this challenging disease. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Introduction: Oral health reflects overall well-being for the elderly population. Compromised oral health may be a risk factor for systemic diseases commonly occurring in old age. Oral health evaluation should be an integral part of the physical examination, and dentistry is essential to qualify geriatric patient care. Aim: To determine the prevalence of oral soft tissue lesions and systemic diseases in institutionalized geriatric population in North India. Materials and Methods: Geriatric patients were clinically evaluated using a standard questionnaire and assessed for known medical illnesses and prevalence of oral soft tissue lesions. Four hundred patients (71% males and 29% females with age ranging from 60 to 100 years were considered in the study group. Twenty-two (33.8% patients were edentulous and seven patients (10.8% were denture wearers. Forty-four (67.69% patients reported with tobacco habits. Results: Most prevalent medical illness reported was diminished vision (15.5%, followed by hypertension (10% and diabetes mellitus (6.25%. Several oral soft tissue lesions were reported among the study population. The most prevalent lesions were leukoplakia (12%, smoker′s melanosis (10%, smoker′s palate (9%, pigmentation on tongue (6%, frictional keratosis (5%, lichen planus (3%, denture stomatitis (2.5%, aphthous ulcers (2%, angular chelitis (1.5%, oral submucous fibrosis (1.5%, melanotic macule (1.5%, candidiasis (1.5%, irritation fibroma (1%, geographic tongue (1%, median rhomboid glossitis (1%, and traumatic ulcer (1%. Conclusion: The findings observed in this population are important and can have a determinant effect on the overall quality of life in this population. This information is a crucial prerequisite for health awareness programs involving the community health workers, oral physicians, and medical professionals.

    Few studies have been conducted in the Saudi population on oral mucosal lesions. The purpose of this study was to evaluate the type and extent of oral lesions in a study among dental patients at a college of dentistry in Saudi Arabia. Over a 3-year period, 2552 dental outpatients were interviewed and investigated clinically for the presence of oral mucosal conditions. A thorough oral clinical examination was performed, including a radiographic examination. The diagnosis was confirmed histopathologically when necessary. Of 383 (15.0%) patients found to have oral mucosal lesions, females constituted 57.7% (n=221) and males 42.3% (n=162). The age range of the patients was between 15 to 73 years with a mean age of 38.2 years. The most commonly affected age group was 31 to 40 years, which comprised 21.4% (n=82) of all affected individuals. The least affected age group were individuals older than 61 years. The most common lesion was Fordyce granules (3.8%; n=98), followed by leukoedema (3.4%; n=86) and traumatic lesions (ulcer, erosion) in 1.9% (n=48). Tongue abnormalities were present in 4.0% (n=101) of all oral conditions observed, ranging from 1.4% (n=36) for fissured tongue to 0.1% (n=2) for bifid tongue. Other findings detected were torous platinus (1.3%; n=34), mandibular tori (0.1%; n=2) aphthous ulcer (0.4%; n=10), herpes simplex (0.3%; n=7), frictional hyperkeratosis (0.9%; n=23), melanosis (0.6%; n=14), lichen planus (0.3%; n=9) and nicotinic stomatitis (0.5%; n=13). The findings of this study provide information on the types and prevalence of oral lesions among Saudi dental patients. This provides baseline data for future studies about the prevalence of oral lesions in the general population. (author)

    The aim of this study was to study and analyze the factors influencing the treatment response to Q-switched alexandrite laser in patients with nevus of Ota and the factors influencing the number of laser sessions. Forty-eight patients treated with Q-switched alexandrite between 2009 and 2013 for nevus of Ota were enrolled in this retrospective, single-center study. The subjects (13 male, 35 female) were divided into three groups according to the number of treatment sessions. Patients were then called back to the hospital for a follow-up interview and examination. Single and multiple variate analyses of various factors were performed. The 48 patients were predominantly female (35 female, 13 male, F:M ratio = 2.7:1), mean age 17.2±10.41. Twenty-five (52.1%) had lesion on the right side of the face, 22 (45.8%) on the left side, and one (2.1%) on both sides. The predominant color was brown (41.7%), followed by cyan (39.6%) and lividity (18.8%). Satisfactory result was observed in all patients, after 3 to 11 treatment sessions (mean 5.37±2); 19 of these (39.6%) needed three to four sessions (short treatment sessions), 22 (45.8%) needed five to seven sessions (intermediate treatment sessions), and 7 (14.6%) needed nine to eleven sessions (long treatment sessions). The clinical response and treatment sessions of the young-age group were significantly better than the adult group. Those with higher Tanino's classification needed more treatment sessions. Dark-colored lesions, which reflect deep melanosis of the lesion, needed more sessions than lighter-colored lesions. As for skin color, better response was obtained in light-skinned patients than in dark-skinned ones. Two patients showed transient hypopigmentation that lasted for less than six months, and recurrence has been seen in one child with dark-colored lesion. Q-switched alexandrite laser is an ideal minimally-invasive method for treating nevus of Ota. Fewer treatment sessions are needed for children and younger

    Full Text Available Food additives are redefined in European legislation (EC Regulation No. 1333/2008. Sulphur dioxide (E220 and sulphite (E221- E228 are widely used in food processing as preservatives because they slow down bacterial growth on foods and prevent oxidation or browning developing on shrimp and lobster. Shellfish processors, farmers and fishermen have long used sulfiting agents in a variety of species of warm and coldwater crustaceans as a treatment to prevent prawns and shrimps melanosis (blackspot, which is a natural process that makes the shell black after harvesting caused by Polyphenoloxidase enzyme systems which remain active during refrigeration or ice storage. Sulfite-induced hypersensitivity is the most well-established adverse response in humans to this food additive. In the present study the presence of sulfites in different frozen and thawed shrimp and prawn species belonging to Penaeoidea superfamily has been evaluated by the Monier-Williams procedure, in order to carry out a risk assessment and evaluate the levels of consumer exposure to this class of additives from these fish products. In addition to assessing and monitoring the correct use of the additive, according to the limits imposed by the European regulations, the correct consumer information on labels was also evaluated. Analysis were performed on both whole shrimp (shell on and inedible parts (head and peeled shell. Sulphites concentration in frozen samples (expressed as SO2 mg/kg mean value±S.D. was 214±17.43 for head on shell on shrimps; 170.73±14.99 for shell on headless shrimps; 112.90±27.55 for peeled and deveined shrimps. Thawed shrimps were purchased at mass retailers channel and local fish markets and local seafood retailers and purveyors: for these samples, all head on shell on, the sulphites concentration (expressed as SO2 mg/kg mean value±S.D. was 160.05±26.15 and 292.54±146.04, respectively. Non-edible parts showed, in all samples, much higher concentrations.

    A significant proportion of groundwater in south Asia is contaminated with arsenic. Pakistan has low levels of arsenic in groundwater compared with China, Bangladesh and India. A representative multi-stage cluster survey conducted among 3874 persons > or = 15 years of age to determine the prevalence of arsenic skin lesions, its relation with arsenic levels and cumulative arsenic dose in drinking water in a rural district (population: 1.82 million) in Pakistan. Spot-urine arsenic levels were compared among individuals with and without arsenic skin lesions. In addition, the relation of age, body mass index, smoking status with arsenic skin lesions was determined. The geographical distribution of the skin lesions and arsenic-contaminated wells in the district were ascertained using global positioning system. The total arsenic, inorganic and organic forms, in water and spot-urine samples were determined by atomic absorption spectrophotometry. The prevalence of skin lesions of arsenic was estimated for complex survey design, using surveyfreq and surveylogistic options of SAS 9.1 software.The prevalence of definitive cases i.e. hyperkeratosis of both palms and soles, was 3.4 per 1000 and suspected cases i.e. any sign of arsenic skin lesions (melanosis and/or keratosis), were 13.0 per 1000 among > or = 15-year-old persons in the district. Cumulative arsenic exposure (dose) was calculated from levels of arsenic in water and duration of use of current drinking water source. Prevalence of skin lesions increases with cumulative arsenic exposure (dose) in drinking water and arsenic levels in urine. Skin lesions were 2.5-fold among individuals with BMI <18.5 kg/m2. Geographically, more arsenic-contaminated wells and skin lesions were alongside Indus River, suggests a strong link between arsenic contamination of groundwater with proximity to river.This is the first reported epidemiological and clinical evidence of arsenic skin lesions due to groundwater in Pakistan.

The prevalence of the dermatosis most often found was respectively: melanosis (53.3%, seborrheic keratosis (46.6%, onychomycosis (37.3%, nevus (33.3%, senile purpura (29.3%, xerosis (14.6%, scabies (12.0% and malignant neoplasm (1.3%. The distribution of dermatosis was 70% (CI95%: 59% to 81% higher in the female population than in the male. CONCLUSION: Notwithstanding the small number of cases, these data are compatible with the few reports available in literature. This study of prevalence defined the distribution of dermatosis in a fraction of the elderly population. However the aggregate data of subsequent casuistries may provide the more precise information whose relevance is undeniable in the orientation of individual and collective future health measures.

    histopathologically diagnosed, the majority of them were benign (n=19, 63.33%. The rest being made up of malignant (n=7, 23.33% and premalignant (n=4, 13.33%. CONCLUSION The most common benign lesion of the eyelid was a chalazion and most common benign lesion of the conjunctiva was melanosis. Basal Cell Carcinoma (BCC, though malignant, has a good prognosis if removed completely. The relative frequencies of squamous cell carcinoma in various studies showed that there was a wide variation. Although, it has been noted that this cancer is seen less frequently in individuals with dark skin, it is interesting to note that the proportion of squamous cell carcinoma was relatively high in this study conducted in India. The results in this study provide further evidence in favour of a higher proportion of sebaceous cell carcinoma in India. The conjunctival malignant neoplasms were dominated by squamous cell carcinoma, which was again in accordance with previous studies in Asian populations.

    . Polyps were classified according to their size, number and location. RESULTS: Mean age was 52.5 ± 11.7 years. Family history for colorectal cancer occurred in 79.8% of individuals. Colonoscopic alterations were detected in 99 individuals: polyps in 64.3%, diverticular disease in 27.9%, inflammatory mucosal alterations in 9.7%, melanosi coli in 2.6% and angioectasias in 7.8%. There were an increasing incidence of polyps in patients older than 50 year. Multivariate logistic regression showed age and sex as predictive factors for polyps (OR = 1.43; 1.19

    Sociedad llegó a constituirse en un poderoso impulsor de varias de las ciencias básicas a mediados del siglo XX, a tal punto que muchos de sus integrantes, además de haber incrementado significativamente su producción científica creyeron necesario organizar sociedades especializadas ya en entomología o en antropología o en botánica, lo mismo que en diversas ramas de la medicina. Si bien las actividades de la Sociedad de Biología decayeron a partir de 1959, tal situación debe entenderse como el fenómeno natural de una madre nutricia que desfallece al dar a luz múltiples productos que en forma independiente siguen sus ideales y principios.

    Y qué no decir de las otras contribuciones a la ciencia y a la medicina que se deben recordar, no por desconocidas, sino porque tienen la importancia que hoy quiere destacar la Academia al otorgar la máxima distinción al doctor Ordóñez. En cuanto a investigaciones, la primera y muy notable, el hallazgo de una nueva modalidad de la contracción muscular, la prosténica, sobre la cual nos hablará más tarde, hallazgo que hizo cuando apenas cursaba el tercer año de medicina, trabajando a la usanza de la época, como preparador del laboratorio de fisiología, cargo al cual se llegaba por riguroso concurso entre los estudiantes.

    Otras muestras de sus investigaciones fueron los estudios sobre resistencia del sistema nervioso central a la anoxia, el hallazgo de un nuevo tipo de melanosis, la melanosis de Ordóñez registrada así en el Diccionario de Jablonsky, los problemas de salud enalturas y sus numerosas publicaciones las más sobre distintos aspectos de las enfermedades cardiovasculares, aparecidas tanto en revistas locales como en aquellas de reconocida importancia internacional por ejemplo Comptes Rendu des Séances de le Societé de Biologie y los Archives des Maladies du Coeur. Sería imposible detallarlas todas.

    Su labor docente, que debe señalarse como una de las más fructíferas, se desarroll

    conjunctival melanomas were BRAF-mutated, and the incidence of BRAF mutations was constant over time. BRAF-mutation status corresponded in conjunctival melanoma and paired premalignant lesions. BRAF mutations were more frequent in males, in young patients, and in tumours with a sun-exposed tumour location (bulbar conjunctiva or caruncle), with a mixed or non-pigmented colour, with absence of primary acquired melanosis, and with origin in a nevus. Immunohistochemistry was able to accurately detect BRAF V600E mutations. In univariate analysis, distant metastatic disease was associated with BRAF mutations. No prognostic associations with BRAF mutations were identified in multivariate analyses. MicroRNA expression analysis revealed 25 tumour-specific microRNAs in conjunctival melanoma. Five possibly oncogenic miRNAs (miR-20b-5p, miR-146b-5p, miR-146a-5p, miR-506-3p and miR-509-3p) were up-regulated. Seven microRNAs (miR-30d-5p, miR-138-5p, miR-146a-5p, miR-500a-5p, miR-501-3p, miR-501-5p and miR-502-3p) were significantly and simultaneously up-regulated in both stage T1 and stage T2 tumours, and were associated with increased tumour thickness. The expression of the 25 tumour-specific microRNAs did not differ significantly between conjunctival melanoma and oral or nasal mucosal melanoma. In conclusion, the incidence of conjunctival melanoma increased in the Danish population from 1960 to 2012. From our findings of a distinct pattern of BRAF mutations and differentially expressed microRNAs, it is evident that conjunctival melanoma is closely related to cutaneous and other mucosal melanomas and bears less resemblance to uveal melanomas. This means that conjunctival melanoma patients may benefit from therapies that are effective for cutaneous and mucosal melanoma. Additionally, the identification of several up-regulated microRNAs may prove to be useful as prognostic or therapeutic targets in conjunctival melanoma. © 2016 Acta Ophthalmologica Scandinavica Foundation.
