Trichoscopy of Aplasia Cutis Congenita of the Scalp in Skin of Color

The document discusses a case of aplasia cutis congenita (ACC) of the scalp in a 25-day-old dark-skinned male, highlighting the use of trichoscopy as a diagnostic tool. Trichoscopic examination revealed unique features in skin of color, such as brown and bright white structureless areas and brown peppering, which differ from findings in lighter skin. Despite these differences, trichoscopy remains useful for diagnosing ACC by identifying peripheral hairs arranged radially and horizontally, a feature not typically seen in other conditions like nevus sebaceous or alopecia areata. The study emphasizes the variability in trichoscopic findings based on skin phototype and the utility of trichoscopy in recognizing ACC in darker skin tones.
