Introduction: Paracoccidio-domycosisis a deep mycosis due to a dimorphic fungus:Paracoccidioides brasiliensis. The principle endemic country is Brazil. We describe the first case of paracoccidio-domycosis, in its cutaneous-mucosal form, diagnosed in French Guiana., Observation: A 20 year-old Brazilian man, having mover to French Guiana a few months earlier, presented with multiple disseminated cutaneous lesions, predominating on the face, and composed of multiple nodules and two ulcerations. The clinical examination also revealed voluminous superficial lymph nodes and ulcerations of the pharynx and larynx. Direct examination, anatomopathology and culture of cutaneous biopsies revealed specific images of Paracoccidioides brasiliensis. HIV serology was negative. Treatment combining cotrimoxazole and itraconazole eliminated the lesions in one month., Discussion: Because the patient had just moved to Guiana, this observation probably corresponded to an imported disease. The principle differential diagnosis was leishmaniosis.

Background: Certain caterpillars produce venomous substances and cases of human envenomation are regularly published., Case Reports: We report 5 cases of caterpillar-induced envenomation observed in French Guyana. The caterpillar bites produced variable clinical manifestations. Automeris liberia provoked acute pain and skin necrosis: Dirphia tarquinia, erythema; Hylesia, persistent erythematous plaque (4 days); Megalopyge, erythematous and edematous lesions at the site of the bite and distant skin lesions; Automeris, syncopal pain and edematous infiltration of the thigh lasting several days., Discussion: Caterpillar envenomation necessitates consultation, emergency unit care, or even hospitalization. It is important to identify the causal caterpillar species in case of envenomation in order to evaluate risk. Lonomia achelous must always be suspected because this species can cause major fibrinogenolysis.
