Onchocerciasis is a devastating tropical disease that makes 18 million people suffer in Africa, the Arabian peninsula and Latin America. It is a filariosis characterized by dermatological, ocular and systemic manifestations and is due to infection by a nematode of the genus Onchocerca volvulus, transmitted by the SIMULIA sting. Parasites live in subcutaneous tissue or tangled in fibrous nodules: onchocercomas. This filariasis is rightly feared for its ocular location that can cause blindness. The specific diagnosis is based on the detection of microfiliars by exsangue biopsy. The mass treatment of populations exposed by ivermectin has resulted in a significant decline in onchocerquian endemicity and global complications over the past decade. We report a case of a young woman of 20 years of Cameroonian origin who consulted for pruritic annular lesions of the legs and torso and in whom the examination found a nodule under mammary which was surgically excised and whose pathological examination has objectified the presence of multiple microfiliars within granulomas.
