Tinea capitis in adults over fifty years of age.

An 89-year-old black woman was examined for generalized folliculitis of the scalp that proved to be tinea capitis caused by Trichophyton tonsurans. To our knowledge, she is the oldest known patient with this condition to be reported to date. Although it is uncommon in adults, this condition must be considered when clinicians are evaluating patients with hair loss and nonspecific scalp dermatitis.
