Dermatophytic disease: A rare case report.

Dermatophytic disease is a rare condition, primarily described in North Africa. This orphan disease owes its name to Hadida and Schousboe. Although the pathophysiology remains poorly understood, it is often associated with immune deficiency and occurs in the context of high consanguinity, as in our case. We report the case of a 24-year-old man who presented a trichophytic disease due to Trichophyton rubrum, admitted for the appearance of numerous subcutaneous nodules, prompting consultation at our institution. This dermatophytic disease typically begins with recurrent ringworm of the scalp or involvement of hairless skin. The dermatophytes involved are of anthropophilic and zoophilic origin, with T. violaceum being the most frequently isolated species in ringworm cases in the Maghreb. To date, no treatment regimen has been established. However, improving immune status and using antifungals have delayed or prevented the visceral dissemination of the disease.
