Trichophyton rubrum as the causative agent of tinea capitis in three children

Summary. Tinea capitis, which is caused by Trichophyton rubrum, is only rarely described in medical literature. Incidence of this disease appears to lie well below 1% in Europe. Microsporum canis, Trichophyton mentagrophytes and Trichophyton tonsurans are the predominant causative agents discussed here. In April 1993 T. rubrum was isolated from typical pathological changes to the capillitium area in three children from a Nigerian family, who had been living in Germany for 3 years. All three children revealed multiple, round or irregularly formed, partially infiltrated, partially pustular, hairless areas measuring up to 2 cm in diameter and covered with tightly clinging scales. The childrens' parents did not suffer from any dermatological complaints. The oldest child had had these pathological changes for about 5 months, the other two for a shorter length of time. Therapy with 10 mg kg‐1 body weight of griseofulvin led to rapid recovery over a period of 4 weeks.
