[Generalized old world leishmaniasis: first Moroccan case in an immunocompetent adult?]

Abstract

Background: Post-kala-azar dermal Leishmaniasis (PKDL) is a rare skin syndrome observed after treatment of visceral Leishmaniasis (VL) with pentavalent antimonial organic salts, never described in Morocco before. Here we report a case in an immunocompetent adult.

Case: A 36-year-old-man from Tata in southern Morocco, with a history of visceral Leishmaniasis 2 years before and treated with meglumine antimoniate and amphotericin B with good clinical course, was hospitalized in dermatology for an erythematous papulo-nodular closet of the face. Six months ago, he presented oral mucosa involvement, then 3 months later, cutaneous lesions appeared on the face. The dermatological examination revealed a papulo-nodular erythematous closet extending to the nose and both cheeks, crusty and lupoid lesions on the forehead, around the eyes and chin, associated with an ulcerative and painless lesion on the heeL. The examination of the oral mucosa revealed an ulceration of the posterior third of the tongue and a papillomatous aspect of the soft palate. The skin biopsy and smear found some amastigote forms of Leishmania bodies. ITS1 PCR was positive (genus Leishmania). The HIV serology was negative. The diagnosis of PKDL was then evoked. The patient received intra-muscular injections of meglumine antimoniate with good progress.

Conclusion: To our knowledge, this is the first case of generalised leishmaniasis suggesting PKDL reported in a Moroccan immunocompetent adult.
