Observations:
A 22-year old woman presented with a 12-year history of masses on her lower abdomen. The lesions started as a single lump and increased in number and size for 6 years, and remained unchanged thereafter. The histologic examination confirmed ectopic mature adipose tissue within dermis that supported the clinical diagnosis of nevus lipomatosis. Because of the cosmetic point of view, the patient underwent staged excision until she was free of lesions.
