RESUMO
The occurrence of mural nodules in serous or mucinous ovarian tumors is not frequent but is currently well established. Mural nodules can developed in benign, borderline or malignant tumors. They can be reactive, benign or malignant. In these situations, the nodule may be carcinomatous, sarcomatous or mixed. Thus, the prognosis of the ovarian tumor can be dramatically modified by the presence of this nodule. About twenty cases of mural nodules of anaplastic carcinoma have been described. We report an additional case of two mural nodules of anaplastic carcinoma associated with bilateral ovarian borderline mucinous tumor. This tumor was synchronous with a renal cell carcinoma. We give details about the classification, the differential diagnoses and prognosis of these nodules.
