Background. Malignant melanomas of the ovary are rare with unpredictable clinical and biological behavior. We present this case report of a metastatic ovarian malignant melanoma, where the ovary was the first site of relapse after 10 years of remission. Case. A 58-year-old postmenopausal woman was incidentally found to have an abdominal mass, 10 years after removal of a cutaneous malignant melanoma lesion. Ultrasound and CT scan revealed an adnexal mass, which was found to be a solitary ovarian tumor at laparotomy. Histology confirmed malignant melanoma metastasis. Conclusion. Relapse after a prolonged period of remission, presenting, as an isolated ovarian metastasis is an unusual presentation of malignant melanoma. As illustrated by this case report, a differential diagnosis of a metastatic malignant melanoma must be considered.
