本文胃癌皮肤转移4例,发现前均无明显消化道症状。皮损特点为限于躯干皮肤的类似非炎症性结节损害,Best粘液胭脂染色可见大量粘液蛋白。胃原发灶以BorrmannⅢ型多见,组织学多为高,中度分化者,生长方式多为巢状或团块状生长。 In this study, there were 4 cases of gastric cancer metastasis and no obvious gastrointestinal symptoms were found before. The skin lesions were characterized by similar non-inflammatory nodular lesions confined to the torso skin, and most of the mucus proteins were visible in Best mucus staining. The primary gastric lesions were Borrmann type III. Most of them were histologically high and moderately differentiated. Their growth patterns were mostly nest-like or mass-like growth.
