胃癌是胃的恶性上皮性肿瘤,包括腺癌,鳞状细胞癌,腺鳞癌,未分化癌,胃母细胞瘤和神经内分泌肿瘤,无胃化生性癌。我们描述了一名69岁的男性胃癌患者,双相组织学形态,其中一个成分由低分化腺癌组成,另一个成分由软骨粘液样基质组成,腺癌过渡到,在两个组件之间没有梭形细胞组件。该病例的组织学形态与产生基质的化生乳腺癌相似。因此,我们将此病例诊断为胃癌,并伴有软骨粘液样基质相似的基质生成化生性乳腺癌。
Gastric cancer is a malignant epithelial neoplasm of the stomach, including adenocarcinoma, squamous cell carcinoma, adenosquamous carcinoma, undifferentiated carcinoma, gastroblastoma and neuroendocrine neoplasms, without gastric metaplastic carcinoma. We describe a 69-year-old male patient with gastric cancer who presented with a novel, biphasic histologic morphology with one component consisting of poorly differentiated adenocarcinoma and the other component consisting of chondromyxoid matrix with adenocarcinoma transition to, between the two components without a spindle cell component. The histological morphology of this case is similar to matrix-producing metaplastic breast carcinoma. Therefore, we diagnose this case as gastric carcinoma with chondromyxoid matrix similar matrix-producing metaplastic breast carcinoma.
