Nevus lipomatosus superficialis is a rare type of benign hamartomatous skin lesion characterized by the presence of mature adipose tissues in the dermis; it usually manifests as a protruding papule or groups of papules or nodules that have smooth or wrinkled surfaces. We report a case of nevus lipomatosus superficialis without external manifestations in a 49-year-old woman. (Korean J Dermatol 2017;55(2):129∼131)
