Introduction:
Angiosarcomas (AS) are rare and aggressive neoplasms originating from the endothelium: they represent less than 2% of all soft tissue sarcomas and usually have a poor prognosis. Although more often primary, different risk factors have been described and some cases are associated with vascular surgery. Materials and Methods: We present the case of an 84-year-old man who developed an AS on his thigh 3 years after a popliteal bypass with autologous saphenous vein. We performed a thorough review of the literature describing the main characteristics of the 25 cases (including ours) of AS associated with vascular surgery reported from 1981 to 2022. Results: Most of the patients were males (21 men vs 4 women) with a range age of 50-84 years. Most of AS are associated with Dacron grafts (12 cases), the overall mean time to onset is 7.8 years after surgery. The most common presenting symptoms are pain (20 cases) and weight loss (10 cases), while cutaneous presentation is uncommon; indeed, violaceous and painful papules, plaques, nodules, and skin ulceration have been found in 3 cases only. Due to unspecific symptoms, differential diagnosis is often difficult and a biopsy for histological confirmation is mandatory. Conclusion: Even if it seems to be a very rare complication, AS should always be considered in patients with compatible symptoms and who have undergone vascular surgery in the past.
