Leiomyoblastoma of the stomach is exceedingly rare. The authors report the case of a 69-year-old woman who presented with acute epigastric pain, anemia and weight loss. She was found to have a malignant leiomyoblastoma (epithelioid leiomyosarcoma) of the duodenum with lymph-node involvement. The clinical and pathological aspects of leiomyoblastoma of the gastrointestinal tract are reviewed, with emphasis on the distinctive, diagnostic histologic features. To the authors' knowledge, this is only the fourth reported case of leiomyoblastoma of the duodenum and the only case in which the tumour was malignant.
胃平滑肌瘤极为罕见。作者报告了一例69岁女性患者，该患者表现为上腹部剧痛、贫血和体重减轻。经检查发现她患有十二指肠恶性平滑肌瘤（上皮样平滑肌肉瘤）并伴有淋巴结受累。本文回顾了胃肠道平滑肌瘤的临床和病理特征，重点关注其独特的诊断性组织学特征。据作者所知，这是第四例报道的十二指肠平滑肌瘤病例，也是唯一一例肿瘤为恶性的病例。
