[An uncommon localization of pyoderma gangrenosum on the penis of an HIV infected patient in the Ivory Coast].

Pyoderma gangrenosum is an uncommon chronic ulcerative dermatosis with unknown aetiology and with a pathology which is still obscure. In 15-45% of cases, it is related to intestinal chronic inflammatory disease (MICI), to a systemic disease that it can sometimes reveals or to an immunodeficiency This disease starts whether with a pustule, a bubble or a nodule which leads during its evolvement to a superficial ulceration with clear edges. Its diagnosis is easy and is mainly clinical. It is a disease which is localized preferably in lower limbs. Treatment is mainly based on oral route corticotherapy. We report a case of gangrenosum pyoderma localized on the penis in a 43-year-old HIV infected patient. It is an uncommon localization, misleading and delicate. We have treated successfully this patient by oral corticotherapy combined with local antiseptic treatments for 6 months.
