A case of hemorrhage due to cutaneous metastatic malignant melanoma controlled with transcatheter arterial embolization and Mohs' paste

Abstract

A 46-year-old man presented with a black nodule on the left thigh that existed since childhood. He visited our hospital because an additional black nodule developed near the existing one. The patient underwent excisional biopsy and was diagnosed with stage IIIA, pT3aN2aM0 malignant melanoma. He underwent additional excision for repeated local recurrence during the early postoperative period. However 6 years later, the tumor was eventually found to be unresectable. In 7 years later, the patient presented to the emergency department with massive arterial hemorrhage from a red nodule on the front of the left thigh and immediately underwent suture ligation to achieve hemostasis. On the following day, he underwent transcatheter arterial embolization of the deep medial/lateral circumflex femoral artery. Mohs' paste was applied after hospitalization, and the tumor gradually turned dark brown, indicating hemostasis. Thus, transcatheter arterial embolization was effective for hemorrhage due to cutaneous metastatic malignant melanoma.[Skin Cancer (Japan) 2015 ; 30 : 108-112]
