We present a case of gastric hibernoma, an unusual tumor with a location novel to the literature. A 39-year-old female presented with one year of upper gastrointestinal bleeding and dysphagia. Gastroenterology performed an esophagogastroduodenoscopy with ultrasound and identified a 6 cm mass within the muscularis propria of the antrum. Computed tomography demonstrated a 9.7 × 7.8 × 4.8 cm heterogeneous antral mass with internal septa. A distal gastrectomy with Bilroth I gastroduodenostomy was performed with 4 cm proximal and 2 cm distal margins. Excision was appropriate to make the diagnosis, exclude malignancy, and remove a symptomatic mass. Hibernoma was confirmed by histopathology. These are rare tumors of brown fat named for their resemblance to the thermogenic tissue found in hibernating animals. They typically present as a slowly enlarging mass of the thigh or shoulder. To our knowledge, this is the first presentation of a hibernoma as a submucosal gastric mass.
我们报告一例胃冬眠瘤，这是一种罕见肿瘤，其位置在文献中尚无先例。一名39岁女性，有一年的上消化道出血和吞咽困难症状。胃肠病科进行了超声食管胃十二指肠镜检查，发现胃窦固有肌层内有一个6厘米的肿块。计算机断层扫描显示一个9.7×7.8×4.8厘米的胃窦部不均匀肿块，内部有分隔。行毕罗一式胃十二指肠吻合术的远端胃切除术，切缘近端4厘米、远端2厘米。切除手术对于明确诊断、排除恶性肿瘤以及切除有症状的肿块是合适的。组织病理学确诊为冬眠瘤。这些是棕色脂肪的罕见肿瘤，因其与冬眠动物体内的产热组织相似而得名。它们通常表现为大腿或肩部缓慢增大的肿块。据我们所知，这是首例以胃黏膜下肿块形式出现的冬眠瘤。
