Nevus lipomatosus cutaneous superficialis.

Area of Science:

• Dermatology
• Pathology

Background:

• Nevus lipomatosus cutaneous superficialis (NLCS) is a rare benign hamartomatous skin tumor.
• It is characterized by mature adipose tissue deposition in the dermis.
• Two distinct clinical forms, classical and solitary, have been documented.

Observation:

• A case report of a young woman with a 13-year history of a solitary, skin-colored tumoral mass on her right buttock is presented.
• The lesion exhibited characteristics of both the solitary type (isolated mass) and the classical type (localization and age of appearance).

Findings:

• Histopathological examination confirmed the diagnosis of nevus lipomatosus cutaneous superficialis.
• The case demonstrated a unique coexistence of clinical features from both the classical and solitary forms of NLCS.

Implications:

• This presentation expands the understanding of the clinical variability of nevus lipomatosus cutaneous superficialis.
• The findings suggest a potential overlap or combined manifestation of the classical and solitary types, which has not been previously reported.
