[Infective dermatitis and recurrent strongyloidiasis in a child].

INTRODUCTION: Infective dermatitis is a chronic childhood dermatosis, associated with HTLV-1 infection. We report the observation of a young Haitian girl in French Guyana. OBSERVATION: An 8 year-old girl presented recurring dermatosis on the scalp and armpits since she was 2 years old. The initial clinical examination showed the presence of centro-facial micro-papules, associated with a nasal pyodermatitis. A bacteriological culture isolated a Staphylococcus aureus. Phenotypic analysis did not indicate any production of exfoliatin or leucocidin. Serologic tests for HTLV1 were positive. In addition, the child presented recurring symptomatic anguillulosis, despite numerous antihelmintic treatments. A clinical and parasitological cure was obtained with a monthly treatment of ivermectin. COMMENTS: This is the first case of infective dermatitis reported in french Guyana. The clinical analysis that led to this diagnosis showed a minor form of this dermatosis. The phenotypic analysis of the Staphylococcus aureus isolated from the cutaneous lesions did not indicate any factors of virulence habitually associated with pyodermatitis in Guyana. This is the first case of chronic digestive anguillulosis (a parasitic complaint usually associated with an adult HTLV-1 infection) associated with an infective dermatitis.
