Abstract

Background:

Inflammatory myofibroblastic tumor (IMT) infrequently involves the sigmoid colon, and has not previously been described in an infant sigmoid colon.

Case report:

An inflammatory myofibroblastic tumor arose from the sigmoid colon of an 11-month-old boy, confirmed by anaplastic lymphoma kinase (ALK), smooth muscle actin (SMA) and desmin immunohistochemical staining. The patient recovered well after complete resection of the tumor.

Discussion:

Sigmoid IMT can occur in infancy. This eighth case is the youngest so far. The child did well after surgical resection.

婴儿乙状结肠炎性肌纤维母细胞瘤一例并文献复习

摘要

背景：

炎性肌纤维母细胞瘤 (IMT) 很少累及乙状结肠，之前也没有在婴儿乙状结肠中发生过描述。

案例报告：

间变性淋巴瘤激酶 (ALK)、平滑肌肌动蛋白 (SMA) 和结蛋白免疫组织化学染色证实，炎性肌纤维母细胞瘤起源于一名 11 个月大男孩的乙状结肠。肿瘤完全切除后，患者恢复良好。

讨论：

乙状结肠 IMT 可发生在婴儿期。这第八例是迄今为止最年轻的。手术切除后，孩子恢复得很好。
