Abstract
Malignant mural nodules in borderline ovarian tumors are rare. Among them, anaplastic mural nodules are infrequent and only limited case reports are available. Here we report a patient diagnosed as borderline ovarian mucinous tumor with an anaplastic carcinomatous mural nodule. She underwent comprehensive staging laparotomy and six cycles of adjuvant chemotherapy with paclitaxel - carboplatin and has no evidence of disease progression at eight months of follow up. This tumor has an aggressive behaviour and patients with stage ≥1C have inferior survival.
