Rhabdomyosarcoma (RMS) is a common soft tissue tumor in adults, but RMS's causes and risk factors are unknown. We present a case of a 62-year-old man with RMS who presented with feelings of fullness after meals and vomiting for the previous five months with anorexia and weight loss for four months. He reported feeling a rolling mass in his belly that moves from left to right. He was initially diagnosed with gastric outlet obstruction due to stomach carcinoma. During the surgical operation, we noted the gross appearance was unlike typical adenocarcinoma or lymphoma of the stomach. Histopathological evaluation of the specimen confirmed a diagnosis of primary epithelial RMS of the stomach. When treating RMS, expertise in immunohistochemistry, molecular biology, genetics, or ultrastructure may be necessary. Information on the appropriate laboratory investigations and management protocol is limited, but an early diagnosis can change the course of treatment and improve patient outcomes.
横纹肌肉瘤（RMS）是成人常见的软组织肿瘤，但RMS的病因和危险因素尚不清楚。我们报告一例62岁男性RMS患者，该患者在过去五个月中出现饭后饱腹感和呕吐症状，伴有四个月的厌食和体重减轻。他报告感觉腹部有一个可移动的肿块，从左向右移动。他最初被诊断为胃癌导致的胃出口梗阻。在手术过程中，我们注意到大体外观与典型的胃腺癌或淋巴瘤不同。标本的组织病理学评估证实诊断为原发性胃上皮性RMS。在治疗RMS时，可能需要免疫组织化学、分子生物学、遗传学或超微结构方面的专业知识。关于适当的实验室检查和管理方案的信息有限，但早期诊断可以改变治疗过程并改善患者预后。
