Solitary Nevus Lipomatosus Cutaneous Superficialis on the Forehead Presenting as a Soft Edematous Plaque / 대한피부과학회지

ABSTRACT

Nevus lipomatosus cutaneous superficialis(NLCS) is a rare nevoid anomaly characterized by ectopic adipose tissue in the dermis. In this disease, two clinical types are distinguished the classical type consisting of grouped papules and nodules, which are distributed linearly over the buttocks or upper thighs, and solitary type consisting of solitary pedunculated or dome-shape nodule without predilection. The solitary type is much rarer than the classical type. Unlike the classical type, the solitary type, especially on the forehead, is often mistaken for another type of benign tumor such as a lipoma. The author experienced a case of solitary NLCS, a 56-year-old female who had flesh, soft and edematous plaque on the forehead with soft surface during 13 months. Histological examination showed ectopic mature adipocytes in the dermis. The lesion was treated by surgical excision.
