Well-demarcated and up to palm-sized scaly erythematous lesions with central healing were observed on the face of a 71-year-old female. A similar, thumb-sized lesion was seen on the left lower leg of a 3-year-old female, and erythematous lesions in the occipital region of a 58-year-old female, a grandmother of the second case, but this was without central healing. Hair in the lesions of the last patient was intact. T. violaceum was isolated on Sabouraud's dextrose agar from the lesional scales of all cases. All 3 had been inappropriately treated with corticosteroid ointment and were successfully treated with antifungal cream. Twenty nine cases of tinea corporis by T. violaceum (glabrum), including these 3, were reported in the Japanese literature from 1969 through 1989; those accompanied by other forms of tinea, such as tinea capitis, are not included in this number. The ratio of females/males was 25/4. Half of the cases were under 12-years-old, while the others were from their 20s to 70s. Nineteen cases (70.4%) had familial history of T. violaceum (glabrum) infection, including tinea capitis. Twelve cases (80%) had been inappropriately treated with corticosteroid ointment. The distribution of the lesions showed a predilection for exposed sites, with the highest frequency on the face, and lesions were usually up to the size of a hen's egg. There were 15 cases of solitary lesion and 9 of multiple lesions. A clinical feature of tinea corporis by T. violaceum (glabrum) may be the solitary occurrence on an exposed site of a female; as stated, though patients were of various ages, 50% were under the age of 12.
