Summary
A rare, benign skin tumor presenting as a long-standing buttock mass was surgically removed. Histological analysis revealed unique cystic structures without atypical cells, confirming a benign diagnosis.
Area of Science:
- Dermatopathology
- Surgical Pathology
Background:
- A 50-year-old patient presented with a long-standing, asymptomatic soft tumor on the right buttock.
- The lesion was pediculated, oval, erythematous, firm, and featured a central keratin plug.
Observation:
- Surgical excision revealed a symmetric intradermal proliferation of uniformly distributed cystic formations.
- The cysts were composed of flat, pluristratified epithelium with laminated keratin and uniform cyst wall thickness.
Findings:
- Histopathology showed no hair-matrix differentiation, basaloid structures, or atypical cells.
- A scanty fibroblastic stroma surrounded some cysts attached to tadpole-shaped epithelial cords.
- Minimal inflammatory infiltration was observed.
Implications:
- This case highlights a rare benign cystic tumor of the skin.
- Accurate histopathological examination is crucial for diagnosis and ruling out malignancy.
