Abstract
A 26-year-old male presented to Primary Care with an asymptomatic papular rash in the supraclavicular area. The patient was initially treated with a topical corticosteroid, followed by a topical antifungal, and had no response to either. The papular rash was later evaluated by Dermatology and diagnosed as juxtaclavicular beaded lines (JCBL), a rare, benign sebaceous gland hyperplasia. The condition is more predominant among African Americans, and is associated with the onset of puberty, and long-term corticosteroid use. The papules of JCBL are typically 1–2 mm, flesh-colored or yellow in color, and arranged in a line adjacent to the clavicles. They are sometimes pierced by a fine hair. Due to their benign nature, JCBL papules do not require treatment. If they are cosmetically bothersome, topical retinoid cream, electrodesiccation, and CO2 lasers can reduce their appearance; however, treatment cannot guard against recurrence.
