Xanthogranulomatous inflammation (XGI) is a rare process. Colonic XGI is extremely rare. We present a case report of XGI arising within an intra-abdominal cyst involving the transverse colon. A 28-year-old man presented with abdominal discomfort. He underwent a computed tomography abdomen-pelvis, which found three subcutaneous collections and a large cystic intra-abdominal structure. The decision was made for resection. Intraoperatively, the cyst originated from the pelvis and was adherent to the surrounding tissues. Histology from the lesion revealed XGI extending into the surrounding tissue. XGI is a rare inflammatory condition. Clinically, it can be difficult to distinguish XGI from an infiltrative malignancy. Therefore, it is usually necessary to obtain a pathological diagnosis of XGI. This case describes an atypical cystic lesion with XGI involving the transverse colon. Although rare, it should be considered in the potential differential diagnosis of an infective or malignant mesenteric cyst.
黄色肉芽肿性炎症（XGI）是一种罕见的病变。结肠XGI极为罕见。我们报告一例发生于累及横结肠的腹腔内囊肿内的XGI病例。一名28岁男性因腹部不适就诊。他接受了腹部-盆腔计算机断层扫描，发现三处皮下积液和一个巨大的腹腔内囊性结构。决定进行切除。术中发现囊肿起源于盆腔，与周围组织粘连。病变组织学检查显示XGI延伸至周围组织。XGI是一种罕见的炎症性疾病。临床上，很难将XGI与浸润性恶性肿瘤区分开来。因此，通常有必要对XGI进行病理诊断。本病例描述了一例累及横结肠的伴有XGI的非典型囊性病变。尽管罕见，但在感染性或恶性肠系膜囊肿的潜在鉴别诊断中应予以考虑。
