摘      要：Malignant melanomas or lymphoma of the skin are malignant tumors of the skin and/or the mucous membranes whose uterine metastases are rare. The secondary uterine localizations, although rare, must be evoked in front of a pelvic tumoral syndrome, or diffuse metastases and a personal past history of melanoma, even after a long time of remission. In our observation, the evolution of the tumor in the pelvis extended to the muscular structures of the uterus and the sigmoid colon of a 72 year old patient, what made it an exceptional case. The diagnosis of these secondary localizations is a diagnosis of elimination, almost always post-operative, made on the histopathological and immunocytochemical study of the surgical specimen, supported by cytogenetics, even molecular biology. The treatment is based on chemotherapy.
