Vasculitis is an inflammatory process of the blood vessels, characterized by leukocyte infiltration in the vessel wall and reactive damage to the mural structures. They have a wide clinical spectrum and can present in a localized or systemic manner. Colonic involvement primarily manifests as abdominal pain and rectal bleeding. Less commonly, it can be associated with colonic perforation or anastomotic leakage after colorectal surgery. We report a case of a 42-year-old man with a history of HIV and proctocolitis who presented with an unexpected vasculitis of the sigmoid colon.
血管炎是一种血管的炎症过程，其特征是白细胞浸润血管壁并对血管壁结构造成反应性损伤。它们具有广泛的临床谱，可以局部或全身的方式出现。结肠受累主要表现为腹痛和直肠出血。较少见的是，它可与结肠穿孔或结直肠手术后的吻合口漏相关。我们报告一例42岁男性病例，该患者有HIV病史和直肠结肠炎，出现了意外的乙状结肠血管炎。
