Spleen metastatic tumor

Splenic metastatic tumors refer to malignant tumors originating from the epithelial system, excluding malignant tumors originating from the hematopoietic system. Most spleen metastatic tumors are metastatic, and Harmann et al. Believe that direct tumor invasion should not be included in metastatic spleen tumors. But most people prefer the former, because the metastatic pathways of malignant tumors are generally considered to be the above three aspects. The metastatic pathway of spleen metastatic cancer is mainly the lymphatic retrograde pathway, but for patients with extensive blood metastasis throughout the body, the spleen can be used as one of the metastatic organs. Metastatic cancerous lesions are often manifested by the majority of nodules or single nodules, but also by most micronodules and diffuse infiltration.
