Acral arteriovenous tumor. A clinicopathologic review
The American Journal of Surgical Pathology
|January 1, 1985
Summary
Acral arteriovenous tumors are benign vascular growths that are often asymptomatic and difficult to diagnose clinically. Histologic examination reveals typical vascular channels, sometimes with a capillary nevus component.
Area of Science:
- Dermatology
- Pathology
- Vascular Biology
Background:
- Acral arteriovenous tumor is a distinct benign vascular neoplasm.
- Clinical diagnosis can be challenging due to its often asymptomatic nature.
- These tumors predominantly affect middle-aged to elderly males.
Purpose of the Study:
- To characterize the clinical and histological features of acral arteriovenous tumors.
- To highlight the diagnostic difficulties associated with this condition.
- To identify common patient demographics and tumor locations.
Main Methods:
- Retrospective review of 47 cases of acral arteriovenous tumors.
- Analysis of clinical histories and patient demographics.
- Histopathological examination of tumor samples.
Main Results:
- Most tumors were asymptomatic and found in healthy middle-aged/elderly males.
- Tumors were predominantly located in acral sites (head and extremities, 79%).
- Histology showed typical venous and arteriovenous channels, with a capillary nevus component in some cases.
Conclusions:
- Acral arteriovenous tumors present diagnostic challenges.
- Clinical presentation is often subtle, necessitating histological confirmation.
- Understanding the histological variations, including capillary nevus components, is important for accurate diagnosis.
