Malignant melanoma, as the name implies, is a malignant tumor of melanocytes, found in the skin, eyes, meningeal lining and the mucosal epithelium of the aero-digestive and genitourinary tracts. Malignant melanoma is typically skin malignancy, which rarely presents at extracutaneous site. Here we present a rare case of primary retroperitoneal melanoma and review the findings in comparison with other cases described in literature.
