An inflammatory myofibroblastic tumor is commonly seen in the lungs but rarely in the appendix. It has a distinct inflammatory cell component and myofibroblastic component. The study presents an inflammatory myofibroblastic tumor of the appendix in an elderly who presented with acute appendicitis and was later found to have an appendicular mass intraoperatively.
Herein, we report a case of inflammatory myofibroblastic tumor of the appendix in a 59 years old female who presented with acute abdomen, features suggestive of acute appendicitis clinically. However, the intra-operative findings showed an appendicular mass involving the base of the appendix for which a right hemicolectomy was done. The histopathological examination of the resected specimen later confirmed it as an inflammatory myofibroblastic tumor of the appendix.
An inflammatory myofibroblastic tumor is common in the lungs, whereas rare in the appendix. It primarily involves children and young adults. It can present as mimic appendicitis or appendicular mass and should thus be considered in the differentials of these.
The rare presentation of inflammatory myofibroblastic tumor of the appendix makes it likely to be missed resulting in overzealous resection of the tumor. Thus, it is important to consider it in the differential diagnosis of acute appendicitis and manage it accordingly.
炎性肌纤维母细胞瘤常见于肺部，但罕见于阑尾。它具有独特的炎症细胞成分和肌纤维母细胞成分。本研究报告了一例发生于老年患者的阑尾炎性肌纤维母细胞瘤，该患者最初表现为急性阑尾炎，术中发现阑尾肿物。
在此，我们报告一例59岁女性阑尾炎性肌纤维母细胞瘤病例，该患者以急腹症就诊，临床特征提示急性阑尾炎。然而，术中发现阑尾肿物累及阑尾根部，遂行右半结肠切除术。切除标本的组织病理学检查后来证实为阑尾炎性肌纤维母细胞瘤。
炎性肌纤维母细胞瘤常见于肺部，而在阑尾中罕见。它主要累及儿童和年轻人。它可表现为类似阑尾炎或阑尾肿物，因此在这些疾病的鉴别诊断中应予以考虑。
阑尾炎性肌纤维母细胞瘤的罕见表现可能导致漏诊，从而导致对肿瘤的过度切除。因此，在急性阑尾炎的鉴别诊断中考虑到它并进行相应处理很重要。
