Glomus tumor (glomus cell tumor) is a rare, often benign neoplasm, which is, in most cases, seen as a solitary bluish nodule involving the nail beds. Solid glomus tumor, glomangioma, and glomangiomyoma are the three main histopathological variants. In this case report, we present the rarest subtype of a glomus tumor, glomangiomyoma, in an atypical location: the stomach. A 45-year-old female from Syria presented to the clinic with severe dizziness and left epigastric abdominal pain accompanied by melena. We performed a thorough clinical study, laboratory workup, upper gastrointestinal endoscopy, endoscopic ultrasound, CT scan, as well as macroscopic and microscopic histologic examination of the surgical specimen, in addition to the immunohistochemical staining. Although rare, gastric glomangiomyoma was diagnosed and a 4.5 × 3 × 3 cm soft tissue mass was resected from the gastric antrum, and no clinical or endoscopic evidence of recurrence was observed for the follow-up duration of 4 years. Undiagnosed gastric lesions with unexplained symptoms should be further investigated and not be disregarded immediately. To the best of our knowledge, this is only the second report of an instance of gastric glomangiomyoma.

胃血管肌瘤：病例报告

血管球瘤（血管球细胞瘤）是一种罕见的、通常为良性的肿瘤，在大多数情况下，它表现为累及甲床的孤立性淡蓝色结节。实性血管球瘤、血管球瘤和血管球肌瘤是三种主要的组织病理学变体。在本病例报告中，我们介绍了非典型位置的最罕见的血管球瘤亚型，即血管肌瘤：胃。一名来自叙利亚的 45 岁女性因严重头晕和左上腹痛伴黑便就诊。除了免疫组织化学染色外，我们还对手术标本进行了全面的临床研究、实验室检查、上消化道内窥镜检查、内窥镜超声、CT 扫描以及宏观和微观组织学检查。虽然罕见，但胃血管肌瘤被诊断为 4。从胃窦切除了 5 × 3 × 3 cm 软组织肿块，随访 4 年未见临床或内镜复发证据。应进一步检查症状不明的未确诊胃部病变，不应立即忽视。据我们所知，这只是胃血管肌瘤病例的第二份报告。
