腺癌淋巴道转移

腺癌淋巴道转移

腺癌淋巴道转移。淋巴结切面可见腺样结构,细胞多形、胞核深染。多种原发癌都可以发生此种转移,肿瘤细胞侵入淋巴管随淋巴液运行转移至淋巴结。体格检查受累淋巴结质硬、无痛、肿大。

This section of lymph node reveals metastases. The metastases are composed of glandular configurations with pleomorphic cells and hyperchromatic nuclei, consistent with adenocarcinoma. A wide variety of primary sites are possible. The most likely primary site is the organ from which the lymph drainage occurs--indicative of local or regional spread. A physical examination may reveal firm, non-tender, enlarged lymph nodes.
