We report a case of multimetastatic malignant melanoma that was diagnosed after histopathologic examination of the excised paratesticular mass. Our patient initially visited the neurosurgery clinic due to low back pain. After preliminary evaluation, he was referred to our clinic due to a right scrotal mass. We excised the paratesticular mass and testis. The histopathologic findings were consistent with malignant melanoma. He was referred to the oncology department for adjuvant treatment. The patient died during the third month of chemotherapy. Our case was unique because the malignant melanoma was widely metastatic and involved primarily paratesticular tissues without any invasion of the testis and epididymis.
