A case of anorectal malignant melanoma with liver metastasis reduced subjective symptoms by transcatheter arterial embolization]

We report a 56-year-old female with anorectal malignant melanoma reduced subjective symptoms by transcatheter arterial embolization (TAE). She had five-month history of melena and epigastric fullness. The physical examination revealed anorectal tumor and hepatomegaly. Pathological examination of the tumor and liver CT scan showed anoreectal malignant melanoma with liver metastasis. Surgical excision of the anorectal lesion and TAE against the liver metastasis improved subjective symptoms remarkably. Liver CT scan after TAE showed necrosis of the metastatic tumors. TAE is effective for palliative treatment of liver metastasis of anorectal malignant melanoma.
