Malignant melanoma caused by malignant transformation of melanocytes is associated with high mortality and is difficult to manage. Metastasis is not uncommon (up to 31% of all cases) and is closely associated with a poor prognosis. Although rare (4–5%), extracutaneous melanoma has been reported; however, primary malignant melanoma of the sacrum is extremely rare (only three case reports to date). Here, we present a 51-year-old patient who underwent surgical treatment for a lesion of the spinal canal and associated bony structures; extensive aggressive resection was required. She underwent partial sacrectomy and lumbo-iliac fixation (to maintain spinal stability). Pathology revealed malignant melanoma. We discuss the diagnosis, surgical intervention, and postoperative follow-up, which may assist clinicians. Although metastatic malignant melanoma is usually fatal, primary extracutaneous melanoma of the spine may respond well to surgery and adjuvant radiotherapy.
