Pleomorphic lipoma of the dermis
The British Journal of Dermatology
|May 1, 1987
Summary
This case study describes a rare pleomorphic lipoma. The tumor exclusively developed in the dermis, involving hair follicle root sheaths with atypical cells.
Area of Science:
- Dermatopathology
- Surgical Pathology
Background:
- Pleomorphic lipomas are rare benign tumors.
- They typically occur in the superficial soft tissues.
Observation:
- A unique case of pleomorphic lipoma exclusively within the dermis is presented.
- The neoplastic tissue specifically involved hair follicle fibrous root sheaths.
- Atypical spindle and multinucleated cells were entrapped within lamellar collagen layers.
Findings:
- The tumor's exclusive dermal location is a distinctive feature.
- Characteristic involvement of hair follicle root sheaths was observed.
- The presence of atypical cells within lamellar collagen is noted.
Implications:
- This case expands the known histopathological spectrum of pleomorphic lipoma.
- Understanding the specific involvement of adnexal structures is crucial for diagnosis.
- A potential origin from the adventitial dermis is suggested for this specific presentation.
