Tinea capitis is rare in adults, although a few cases have been described i
n HIV-infected patients. We present two cases in black African adults who w
ere HIV positive. In one, the condition led to the diagnosis of HIV infecti
on. It is possible that the rarity of tinea capitis in HIV-positive adults
could be related to increased colonization of their scalp by Pityrosporum (
Malassezia) spp. In patients well controlled with an antiviral therapy, the
treatment of tinea capitis seems no more difficult than in non-immunosuppr
essed patients. There is possibly a relation between clinical presentation
and degree of immunodeficiency.
