Summary
A rare avascular leiomyoma originating from a digital artery in the thumb was successfully removed. Preoperative vascular assessment may aid in diagnosing these painful hand tumors.
Area of Science:
- Vascular Surgery
- Orthopedic Surgery
- Dermatopathology
Background:
- Leiomyomas are rare tumors originating from smooth muscle.
- Hand leiomyomas, particularly those arising from digital arteries, are exceptionally uncommon.
- Diagnosis of hand leiomyomas is often challenging based on clinical presentation alone.
Observation:
- A 60-year-old woman presented with an avascular leiomyoma originating from a digital artery in her thumb.
- The tumor caused significant pain, a characteristic that can distinguish it from other benign hand tumors.
- Preoperative evaluation of vascular function was considered a potential diagnostic clue.
Findings:
- The patient underwent successful en bloc excision of the digital artery leiomyoma.
- The leiomyoma was noted to be avascular, highlighting a spectrum within vascular smooth muscle tumors.
- Histopathological confirmation of leiomyoma arising from the digital artery.
Implications:
- This case underscores the importance of considering leiomyomas in the differential diagnosis of painful hand masses.
- Preoperative vascular imaging may be beneficial in identifying potential digital artery leiomyomas.
- Understanding the spectrum of vascularity in smooth muscle tumors is crucial for accurate diagnosis and treatment planning.
