Malignant Melanoma of the Nose
-A Case that 3D-CT was Helpful for Detecting Sentinel Lymph Node-

Abstract

A 71-year-old man consulted our hospital because he noticed small black patch on his nose several month ago. Excisional biopsy was done and he was diagnosed as having malignant melanoma. Extended excision and sentinel lymph node biopsy, which was negative, were performed as additional treatment. In this case, 3D-CT lymphography which was taken after injection of Iopamiron370 around the primary legion was useful to detect the position of the sentinel lymph node.
