Melanoma is the deadliest malignancy of the skin with an estimated 91 000 new annual cases with 9300 deaths in 2018. Metastatic disease generally presents with identification of known primary lesion; however, in 3.2% of patients, metastatic disease is discovered with unknown primary lesion/site. Rarely, melanoma is diagnosed as a primary lesion in visceral organs. Suspected primary hepatic melanoma is exceedingly rare and described in only a few case reports. We present the case of a 69-year-old Caucasian male who was found to have a hepatic melanoma on final pathology after resection of suspected primary hepatic malignancy. After a thorough postoperative workup, a primary lesion was unable to be identified. As such, a visceral primary lesion is considered.
