Summary : A 53-year-old French Caucasian man living in Conakry (Guinea) and working as a manager to build a golf course in a mangrove area, was evacuated to France and referred to our clinic in March 1997, with a recent history of a painless erythematous papule on the dorsal side of the right ankle with fever accompanied by chills and weakness, and followed by a second lesion on the left lower leg. The patient was unaware of being bitten by a tsetse fly during the previous weeks.
At clinical examination, the body temperature was 39.5°C, and two respectively 12 cm and 9 cm indurated pruritic, erythematous and purpuric plaques were found on the right ankle and the left foot (Figs. 1 and 2). There was a satellite inflammatory lymphadenopathy located at the right inguinal site. The liver and the spleen were palpable. The remaining integument and the other physical findings, including those of the neurological examination, were unremarkable. Laboratory investigations reported a moderate thrombopenia and a marked leucopenia. Examination of a CSF specimen demonstrated a normal cell count (less than 1 element/mm3). Laboratory evaluation of blood specimens is showed (Fig. 3). |
