A2 - Appachi, Elumalai PY - 2015 T2 - The Color Atlas of Pediatrics AB - An otherwise healthy 7-year-old boy is seen in a homeless shelter with a 2-month history of patchy hair loss (Figure 120-1). Various anti-dandruff shampoos had not helped. On physical exam, there are moderate areas of patchy alopecia with significant scaling of the scalp. Posterior cervical adenopathy could be seen and palpated on the left side. There was no fluorescence with a Wood’s lamp indicating that this fungal infection was most likely Trichophyton tonsurans. The pediatrician easily identified this as tinea capitis but decided to confirm the diagnosis with a KOH preparation. Some of the scale was scraped from the scalp using two microscope slides (one to scrape and another to catch the scale). KOH was added and a coverslip placed. Branching hyphae were seen under the microscope. The child was treated with oral griseofulvin at 20 mg per kilogram per day. At the 4-week follow-up there was significant improvement, no reported side effects of the griseofulvin, and the treatment was continued for an additional 4 weeks.
