Radiologic spectrum of melanoma metastatic to the gastrointestinal tract.

Radiologic experience in 67 patients with melanoma metastatic to all portions of the gastrointestinal tract is reviewed. Besides the well known "bull's-eye" lesion of the upper gastrointestinal tract, a large variety of radiologic presentations of melanoma metastases is discussed and illustrated. Because of extended survival due to improved chemotherapy and immunotherapy, the importance of careful radiologic examination of the melanoma patient is stressed.
