Generalized Asymptomatic Cutaneous Pits and Comedones in a Young Woman

A 22-year-old woman presented with multiple asymptomatic, progressive dark papular and pitted skin lesions over the past 5 years, with a similar history in her father. Examination and biopsy confirmed a diagnosis of follicular Dowling-Degos disease (DDD), a rare variant of the classical form of the disease, characterized by lesions confined to hair follicles. Histology showed features similar to classical DDD but limited to the follicular infundibular epithelium. The patient was informed about the disease and the lack of curative treatment, and was offered fractional carbon dioxide laser resurfacing for cosmetic improvement, but was lost to follow-up. This case highlights the importance of recognizing follicular DDD for appropriate diagnosis and management.
