title: Primary retroperitoneal malignant melanoma: A case report.
abstract: Primary malignant melanoma occurring at an extra cutaneous site is rare. A case of primary malignant melanoma located in the retroperitoneum of an 18-year-old female is presented in this study. Histopathological examination of the tissue biopsies at laparotomy with immunohistochemical stains confirmed a diagnosis of malignant melanoma. Further extensive clinical and radiological investigations proved the retroperitoneum to be the primary site.
