作者报告1例转移性皮肤癌.患者男51岁,在肺癌治疗过程中,右侧头部出现红色肿瘤,组织像为转移性管状腺癌.见到肿瘤细胞经毛囊及部分表皮排出,认为是排出现象(elimination).作者从本例观察到:①毛囊内至开口部肿瘤细胞呈巢状分布.②毛囊上皮围着肿瘤细胞伸展.③肿瘤细胞巢与真皮内肿瘤细胞连接.④毛漏斗部的毛囊上皮基底层附近可见孤立的肿瘤细胞.⑤肿瘤细胞侵入表皮破坏基底膜.在连续切片中观察数个毛囊,肿瘤细胞侵入增殖而破坏毛囊上皮的未见到,保持了毛囊上皮的形态又排出肿瘤细胞.考虑为排出现
The authors reported 1 case of metastatic skin cancer. The patient was male 51 years old. During the treatment of lung cancer, there was a red tumour in the right head. The tissue resembled a metastatic tubular adenocarcinoma. The tumour cells were seen through the hair follicle and part of the epidermis. Elimination. The authors observed from this example: 1 that the tumor cells in the hair follicle to the opening are nested. 2 The hair follicle epithelium extends around the tumor cells. 3 The tumor cell nest is connected to the intradermal tumor cells. Isolated follicle epithelial basal layer near the isolated tumor cells. 5 Invasion of tumor cells into the epidermis destroys the basement membrane. Several hair follicles are observed in successive sections. The invasion of the tumor cells invades the hair follicle epithelium, but the morphology of the hair follicle epithelium is preserved. Excrete tumor cells. Consider the row appears
