We report a case of retractile mesenteritis presenting as an abdominal mass with incomplete small-bowel obstruction. Histological features included fat necrosis, fibrosis, elastosis, dystrophic calcification, and chronic inflammation. Lymphatic obstruction resulted in the accumulation of lipid-laden macrophages in the ileal mucosa. Ultrastructurally, myofibroblasts were the principal cells present. The differential diagnosis of retractile mesenteritis is discussed with particular attention to myofibroblastic disorders such as inflammatory pseudotumors, desmoids, retroperitoneal fibrosis, and other uncommon conditions that appear to be morphologically or clinically distinguishable although the etiology and pathogenesis are obscure.
我们报告一例以腹部肿块伴不完全性小肠梗阻为表现的回缩性小肠炎。组织学特征包括脂肪坏死、纤维化、弹性组织变性、营养不良性钙化和慢性炎症。淋巴阻塞导致富含脂质的巨噬细胞在回肠黏膜积聚。超微结构上,肌成纤维细胞是主要存在的细胞。本文讨论了回缩性小肠炎的鉴别诊断,特别关注肌成纤维细胞性疾病,如炎性假瘤、硬纤维瘤、腹膜后纤维化以及其他一些虽病因和发病机制不明但在形态学或临床上似乎可区分的罕见病症。
