Abstract

Three cases of Trichophyton violaceum infection seen in one family over a 6-year period are reported. Their clinical features were; case 1, a proband, seven-month-old boy with black dot ringworm; case 2, a 59-year-old female with tinea faciei, the grandmother of case 1, and case 3, a 6-month-old boy with tinea faciei and black dot ringworm, the brother of case 1. The lesions recurred repeatedly in each patient over several years, strongly suggesting that the fungus, T. violaceum, a representative of anthropophilic dermatophytes, had remained subclinically on the skin surface of the family members and thus caused the infections. However, all attempts to isolate the fungus from the scalps of healthy family members with a toothbrushing regimen proved unsuccessful.
