This is a case report of an extremely rare primary malignant melanoma, presenting in the retroperitoneum of a 76 year old male. USG and CT scan revealed a large retroperitoneal, well defined, 8.6x5.1cm mass in the retrocaval compartment, displacing the IVC anteriorly. Multiple tiny, hypodense/cystic, hepatic metastases were seen predominantly in the superior segments of the right lobe. Minimal peritoneal free fluid was seen. Fine needle aspiration cytology revealed features whichwere suggestive of malignant melanoma, which was followed by a biopsy of the retroperitoneal mass. The histopathology of the biopsy was suggestive of malignant melanoma. The detailed clinical history revealed that there was no previous melanoma which was excised or regressed, and that the patient did not have any lesions on the skin or in the eyes or in the gastrointestinal tract. So, the case was diagnosed as primary retroperitoneal malignant melanoma – A RARE FINDING with only 5 cases in the literature.
