A Case of Extensive Nevus Comedonicus / 대한피부과학회지

ABSTRACT

Nevus comedonicus(NC) is an uncommon skin disorder, which appears as linear groups of open comedones clinically. A 56-year-old male patient presented a painful walnut-sized erythematous nodule with pus-like discharge on the right posterior aspect of the neck. He has extensive comedone like lesions on the right side of the body after his birth and has suffered from recurrent infections. Histopathologic finding showed the typical features of nevus comedonicus, wide and deep invagination of the epidermis filled with keratin plugs. He was treated with incision, pus drainage and systemic antibiotics. We report a case of extensive nevus comedonicus.
