[Cutaneous leishmaniasis of the vermilion border of the upper lip extending to the oral mucosa]. / Leishmaniose cutanée du vermillon avec atteinte muqueuse de la lèvre supérieure.

BACKGROUND: Cutaneous leishmaniasis is endemic in Morocco. Mucosal involvement is rare. We report a case in Morocco of cutaneous leishmaniasis of the vermilion border of the upper lip extending to the oral mucosa due to Leishmania tropica. PATIENTS AND METHODS: A 15-year-old girl was seen with 2 ulcerated lesions, present for 4 months, situated on the left cheek and vermilion border and extending to the oral mucosa. The diagnosis of leishmaniasis was confirmed by direct examination revealing high numbers of Leishmania amastigotes. Culture of the offending organism in NNN medium and isoenzymatic characterization resulted in identification of L. tropica. Treatment with meglumine antimoniate (Glucantime) was ineffective. The outcome was good after treatment with fluconazole. CONCLUSION: In Morocco, cutaneous leishmaniasis with mucosal involvement is rare, and usually develops as a complication of cutaneous leishmaniasis via direct extension.

Giant perianal condyloma acuminatum in an infant without sexual abuse.

Giant condyloma acuminatum is rare in infants. We report a case of giant perianal condyloma in a 10-month-old infant without sexual abuse. The patient was treated by surgical excision associated with electrocoagulation with no recurrence after 2 years. While both sexual and nonsexual transmissions are possible in patients with condyloma acuminatum, sexual abuse must always be considered in children.

[Nicolau livedoid dermatitis with severe neurological involvement in a child]. / Dermite livédoïde de Nicolau avec atteinte neurologique sévère chez un enfant.

BACKGROUND: Nicolau syndrome is a rare condition consisting in tissue ischemia and necrosis following intramuscular, intra-articular or subcutaneous injection. PATIENTS AND METHODS: Immediately after gluteal intramuscular injection of benzathine-penicillin, a 10-year-old male child presented an extensive painful violaceous lesion on the left buttock associated with urinary incontinence and left lower-limb paresis. Additional underlying muscular damage was supported by high serum levels of creatine kinase and lactate dehydrogenase. Treatment was based on fluid expansion, intravenous steroids and anticoagulants, resulting in improvement of cutaneous and muscular lesions. Improvement in terms of neurological dysfunction was obtained after regular neuromuscular rehabilitation. DISCUSSION: This case underlines the need to prevent Nicolau syndrome by means of compliance with the technical recommendations for intramuscular injections.

[In-transit metastasis in melanoma: Efficacy of topical imiquimod combined with carbon dioxide laser or with electrocautery]. / Métastases en transit du mélanome : efficacité de l'imiquimod topique combiné au laser CO2 ou à l'électrocoagulation.

BACKGROUND: In-transit metastases in cutaneous melanoma are common and difficult to manage. Therapy is mainly palliative. Use of topical imiquimod has been assessed for surface metastases. PATIENTS AND METHODS: We report on four patients with cutaneous melanoma metastases treated with topical imiquimod associated with carbon dioxide laser in the first two patients and with electrocoagulation in the two others. For two patients, we noted complete regression of the lesions after 15 and 18 months. For the two others, treatment was stopped after 9 to 10 months because of progression of subcutaneous metastasis and distant metastasis. DISCUSSION: Topical imiquimod is an alternative treatment used in superficial in-transit metastasis of melanoma. Its use as a monotherapy is sometimes ineffective. We elected to use combined pre-treatment with carbon dioxide laser or electrocoagulation in order to potentiate the action of imiquimod. This simple and inexpensive therapeutic strategy constitutes a palliative treatment that can allow prolonged local control of cutaneous metastasis.

[Nodular cutaneous amyloidosis associated with Sjögren's syndrome]. / Amylose cutanée nodulaire et syndrome de Gougerot-Sjögren.

BACKGROUND: Cutaneous nodular amyloidosis is rare, and association with Sjögren's syndrome has been reported. We discuss the possible link between these two diseases based on a case we saw. PATIENTS AND METHODS: A 78-year-old woman with Sjögren's syndrome ongoing for 17 years presented for evaluation of a waxy infiltrated lesion on her left leg that had appeared 6 months earlier. Histopathological examination revealed a deposit of homogenous eosinophilic material throughout the dermis consistent with amyloidosis. Immunohistochemical study showed these deposits to be AL immunoglobin light chains. DISCUSSION: The association of cutaneous nodular amyloidosis and Sjögren's syndrome appears to be a distinct disease entity reflecting the polymorphic clinical spectrum of lymphoproliferative diseases related to Sjögren's syndrome.
