Tinea capitis due to Microsporum gypseum in an adult.

A case of tinea capitis due to Microsporum gypseum in an adult is described. An otherwise healthy 69-year-old woman presented two large patches of slightly erythematous scaling alopecia localized on the vertex and on the left parietal region of the scalp. The only subjective sign was itching. A mycological culture was positive for Microsporum gypseum. Tinea capitis is uncommon in adults; furthermore, isolation of Microsporum gypseum from this type of lesion is rare.
