Synchronous Primary Endometrial Carcinoma and Metastatic Malignant Melanoma in Cervical Lymph Node.

The occurrence of dual malignancies is not rare but concurrent occurrence of two malignancies with different histogenesis and different anatomical sites is not known. In the studies which have been conducted so far, none of them has shown the simultaneous occurrence of metastatic malignant melanoma and primary endometrial carcinoma. We report herein a case of a 42-year-old female diagnosed with metastatic malignant melanoma in cervical lymph node with unknown developing primary endometrial carcinoma within two months. No foci of primary malignant melanoma were found in uterus. Dual primary malignancy is being suggested by the presence of two malignancies in a patient with different morphological picture on histopathological examination, at anatomically distinct sites. Malignant melanoma and endometrial carcinoma, being a rare combination, prompted us to report the case.
