Abstract

INTRODUCTION AND IMPORTANCE

Primary inflammatory myofibroblastic tumor is a rare subgroup of mesenchymal tumors. Gastric localization is extremely rare, and patients may present with abdominal pain and a palpable abdominal mass. Here, we present a case of gastric inflammatory myofibroblastic tumor revealed by abdominal pain, which was treated with wide local excision.

CASE PRESENTATION

This report illustrates the case of a 55-year-old female who presented with abdominal pain. Imageology and gastrointestinal endoscopy revealed a posterior gastric mass, which was treated with wide local excision. Immunohistochemical analysis of the specimen confirmed the diagnosis of inflammatory myofibroblastic gastric tumor. The patient had an uneventful postoperative course and she remained in remission after 6 months of follow-up.

DISCUSSION

Inflammatory myofibroblastic tumor is a very rare mesenchymal tumor that usually affects children and young adults. Gastric localization is also very rare and does not typically cause specific clinical symptoms. Surgery is the mainstay of treatment, and resection depends on the size and location of the lesion. The definitive diagnosis is confirmed by immunohistochemical analysis of the specimen.

CONCLUSION

Myofibroblastic tumor is a rare subgroup of mesenchymal tumor. Gastric localization is an uncommon presentation. Surgery is the mainstay of the treatment. Histological analysis of the surgical specimen is essential for a final diagnosis.

摘要

引言与重要性

原发性炎性肌纤维母细胞瘤是间叶性肿瘤中一个罕见的亚组。胃部定位极为罕见，患者可能表现为腹痛和可触及的腹部肿块。在此，我们报告一例因腹痛发现的胃炎性肌纤维母细胞瘤病例，该病例接受了广泛局部切除治疗。

病例介绍

本报告阐述了一名55岁女性因腹痛就诊的病例。影像学和胃肠内镜检查发现胃后部有一肿块，遂对其进行了广泛局部切除。对标本进行免疫组织化学分析确诊为胃炎性肌纤维母细胞瘤。患者术后恢复顺利，随访6个月后仍处于缓解状态。

讨论

炎性肌纤维母细胞瘤是一种非常罕见的间叶性肿瘤，通常影响儿童和年轻人。胃部定位也非常罕见，通常不会引起特定的临床症状。手术是主要的治疗方法，切除取决于病变的大小和位置。通过对标本进行免疫组织化学分析来确诊。

结论

肌纤维母细胞瘤是间叶性肿瘤中一个罕见的亚组。胃部定位是一种不常见的表现形式。手术是主要的治疗方法。手术标本的组织学分析对最终诊断至关重要。
