Solitary metastatic endometrial carcinoma of the spleen.

Carcinomatous metastatic involvement of the spleen usually indicates widespread malignant disease. Solitary metastatic lesions in this organ are exceedingly rare and the literature reveals fewer than 15 cases. We have observed a poorly differentiated adenocarcinoma of the body of the uterus (adenoacanthoma) with an unusual route of metastasis in a 59-year-old patient. Only one case with the same pattern of spread from an endometrial carcinoma has been reported earlier.
