Soft tissue melanoma was first described by Enzinger in 1965 under the name of clear cell sarcoma. In 1983, Chung and Enzinger renamed it soft tissue melanoma due to its immunohistochemical similarities with melanoma. We here report the case of a 22-year old young man with this rare type of melanoma, presenting with molluscoid lesion on his ankle without any clinical sign of malignancy. Histology examination confirmed the diagnosis of soft tissue melanoma.

Background: Mucormycosis is an opportunistic fungal infection, typically affecting immunocompromised patients. Rhino-orbital location is the most frequent form with cerebral blood vessels invasion and a fatal outcome., Case Report: An immunocompetent 38-year-old woman, with previous history of primary cutaneous mucormycosis, was admitted for a febrile erythemato-oedematous lesion of the face with well-demarcated edge evoking erysipelas. No cutaneous portal of entry was identified. Oral cavity examination found an ulceronecrotic lesion of the hard palate. Diagnosis of mucormycosis was retained after nasal endoscopy and histological findings. The patient was first treated for erysipelas, then by ascending dose of intravenous amphotericin B. A good outcome was observed despite the occurrence of nephrotoxicity which normalized by alkaline hyperhydratation. Healing was obtained after 1month of effective dose leaving cleft palate sequelae., Discussion: Mucormycosis occurs rarely in immunocompetent, even more if it is a second episode. Affecting the face, it may simulate or be revealed by superficial skin infection. Within that, a meticulous otorhinolaryngeal examination is required when the portal of entry is not obvious., (Copyright © 2011 Elsevier Masson SAS. All rights reserved.)

Blastomycosis is a systemic fungal infection caused by a thermally dimorphic fungus, Blastomyces dermatitidis. The incidence in immunocompromised patients has increased in the last two decades. A 55-year-old man consulted for inflammatory nodules on the forearm. Biopsy of one nodules showed a pseudoepitheliomatous hyperplastic epidermis overlaying a dense agranulomatous inflammatory infiltrate containing free-formed ovoid bodies enclosing giant macrophageous cells. These findings were consistent with blastomycosis. After a month of treatment cutaneous lesions regressed partially but the patient's general status continued to deteriorate with the appearance of an edematous-ascitic syndrome and icterus. Laboratory blood testing demonstrated cholestasia and abdominal ultrasound showed hepatosplenomegaly. Needle liver biopsy revealed giant B-cell lymphomatous infiltration of the hepatic ducts. The patient's condition worsened rapidly and he died five months after diagnosis despite four rounds of chemotherapy. Blastomycosis is rare in Morocco. Primary infection is usually a pneumonic process. Isolated cutaneous infection is possible but uncommon. To our knowledge the association of blastomycosis and intravascular lymphoma has not been previously reported. In immunocompromised patients, clinical findings can be alarming and the outcome can be rapidly fatal.

Wohlfahrtia magnifica is a frequent fly in countries with high breeding activity: Australia, South Africa or Arab country The parasitological infestation occurred essentially during the summer, favourable period to the biological evolution of the flies. In this work, we report one case of wound myiasis that complicates a cutaneous lesion caused by larvae of Wohlfahrtia magnifica. This observation constitutes the first human case in our country.

Background: Nutritional disorders observed in children with eczema may be aggravated by inappropriate diet, sometimes with dramatic effects., Case Report: A child aged 3 years 7 months presented a state of severe malnutrition with edema (kwashiorkor). The child had chronic eczema and had been given a highly restrictive diet based on a principle of exclusion without medical advise. Cure was achieved without sequelae with a normal diet., Discussion: This case illustrates the fragility of nutritional status in children with chronic widespread skin disease due to the risk of cutaneous loss of protein. Kwashiorkor is an exceptional observation in developed countries and, in this context, might be on the rise due to the popularity of exclusion diets for presumed allergic disease.

Background: Blastomycosis is an uncommon chronic granulomatosis caused by Blastomyces dermatitidis. We present a case with a skin localization that disclosed malignant corticoadenoma., Case Report: A 32-year-old man consulted for inflammatory nodules of the face and lower limbs. The histological examination of a nodule biopsy was in favour of blastomycosis. Ketoconazole treatment was ineffective. Amphotericin B provided cure of the skin lesions. Search for extension disclosed a malignant corticoadrenoma., Discussion: Blastomycosis is very rare in Morocco. The portal is usually the lung. Unique skin involvement is very exceptional. To our knowledge this is the first report of a blastomycosis-corticoadenoma association. The clinical situation may be alarming in immunodepressed subjects. Amphotericin B treatment is indicated.
