We describe herein a case of amelanotic melanoma of the rectum. Macroscopically, the tumor was lacking in pigmentation and microscopically, it was found to be deficient in melanin. Moreover, the tumor cells showed positive staining for HMB-45, the antimelanoma antibody, which led to a diagnosis of amelanotic melanoma. The patient died of metastatic tumors in the liver and bone 17 months after undergoing abdominoperineal resection of the rectum and dissection of the bilateral inguinal lymph nodes.
