Nevus lipomatosus cutaneous superficialis presenting as papilloma: A case report

Abstract

Nevus Lipomatosus Cutaneous Superficialis (NLCS) is an uncommon hamartomatous lesion of the skin. NLCS is classified into two clinical forms classic and solitary. Some authors consider this lesion as a type of connective tissue nevus. We report a rare case of solitary NLCS in a 69 year old male with a long history of pedunculated swelling in the right gluteal cleft with review of literature. On gross appearance the lesion was a grey brown, exophytic, cerebriform, smooth skin covered soft tissue mass measuring 4.5 cms in the largest dimension with a broad peduncle attached. On histopathological examination the lesion showed superficial and deep dermal infiltration of the adipose tissue with distortion of the dermal collagen.
