Summary
A rare angioleiomyoma was found within a cellular histiocytoma in a patient. This finding suggests vascular origins within the histiocytoma, offering new insights into tumor development.
Area of Science:
- Dermatopathology
- Surgical Pathology
Background:
- Cellular histiocytomas are benign skin tumors.
- Angioleiomyomas are benign tumors of smooth muscle and vessels.
Observation:
- A 77-year-old man presented with a lesion on his calf.
- The lesion was a nodule with concentric areas: an outer cellular histiocytoma and an inner angioleiomyoma.
Findings:
- Immunoperoxidase staining confirmed desmin positivity in the angioleiomyoma, while the histiocytoma was negative.
- No connection was found between the angioleiomyoma and a trapped vein.
Implications:
- This case suggests a potential origin of angioleiomyoma from vessels within a cellular histiocytoma.
- Highlights the complex nature of cutaneous neoplasms and their potential origins.
