{Abstract}: Gastrointestinal angiosarcoma is an extremely rare malignant tumor of the digestive tract, characterized by a very poor prognosis, with few patients surviving more than 1 year after diagnosis. This case report describes a 71-year-old female patient with a 3-year history of intermittent abdominal pain and significant exacerbation of abdominal pain and bloating 2 weeks prior to treatment. After surgical treatment, the pathological and immunohistochemical diagnosis was primary epithelioid angiosarcoma of the jejunal mesentery. The patient refused postoperative adjuvant chemotherapy and died 4 months after diagnosis due to widespread systemic metastasis. In addition, this article reviews 38 previously reported cases of primary gastrointestinal angiosarcoma, aiming to further understand angiosarcoma and thus guide clinical practitioners in providing more comprehensive treatment approaches.
