| Summary: | Tinea capitis is a common dermatophyte infection affecting scalp and hair of pre-pubertal children. With introduction of Griseofulvin
in 1958, there has been considerable improvement in the treatment of tinea capitis. A seven-year-old male child was brought to the
dermatology clinic. He presented with diffuse white scaly patches of alopecia on scalp of one-year duration. The child was sent to the
microbiology section of the National Health laboratory, Botswana for the collection of the samples. The samples consisted of scalp
scrapings and few plucked hairs from the suspicious areas, which were collected by swab and scalpel blade methods. Potassium
hydroxide (10% KOH) mounts were prepared for scales and hair samples. Scales were positive for fungal elements and endothrix type of
perforation was seen in hair. Cultures on Sabouraud’s dextrose agar (SDA) and Derm agar were incubated at 25°C, which yielded white
variant of Trichophyton violaceum after two weeks of incubation. T. vioaceum (white variant) grew in all the plates. After six weeks of
treatment with griseofulvin, the repeat culture grew only T. violaceum (violet strain). The child showed a definite clinical improvement. |
