Tinea capitis in adults in southern Taiwan.
We report the clinicomycologic study of 27 culture-proven cases of tinea capitis from southern Taiwan during the years 1988 to 1990. The series is notable for its predominance of adults (63%), of women (89%), and of Trichophyton violaceum infection (74%). The age distribution was clearly bimodal; the median age was 6 years for children and 56 years for adults (older than 18 years). Whether or not these findings represent a new trend of tinea capitis in southern Taiwan remains to be determined. Clinically, our cases of black-dot ringworm caused by T. violaceum often presented with subtle changes of scaling, hair loss, and black dots. The keys to the correct diagnosis are (1) a high clinical index of suspicion with careful inspection of the scalp for the presence of black dots, and (2) microscopic examination and culturing of the black dots or plucked hairs.
