Tinea Capitis: Bedside Diagnosis by Dermoscopy

An otherwise healthy 8-year-old girl presented with a 2-month history of mildly pruritic, area of alopecia on her scalp. Examination revealed a well-circumscribed, annular (4  × 3 cm), slight scaly, noninflammed, grayish-white patch of hair loss (Figure, A). Marked hair fragility was elicited on hair pull; no cervical lymphadenopathy was noted. Other mucocutaneous sites were uninvolved. Dermoscopic (Dermlite, DL4, polarized/contact mode, 10×, San Juan Capistrano, Ca lifornia) evaluation of the alopecic patch showed multiple black dots, comma hair, and corkscrew hair along with peripilar scales (Figure, B).
