Tinea Capitis in The Netherlands (Rotterdam Area)

This retrospective study reviews the occurrence and treatment of various forms of tinea capitis at the out‐patient clinic for Dermatology and Pediatric Dermatology of the University Hospital Sophia/Dijkzigt over the period 1977–1988. Tinea capitis was diagnosed in 64 children. Trichophyton violaceum was the pathogen most frequently isolated, with Microsporum canis ranking second. The potassium hydroxide preparation was positive in 58 % of the cases. Four cases showed a positive potassium hydroxide preparation with a negative culture. Immigrant children from Morocco were the largest group (61 %). A zoophilic dermatophyte was isolated in 15 cases (27 %). A pet animal was the source of infection in 4 cases. The ratio between boys and girls was equal in the patient population studied. In 43 % of the children suffering from tinea capitis the clinical features were mild flaking without hair loss (so called seborrheic dermatitis‐like infection).
