In 10 patients with gastrointestinal metastases from cutaneous malignant melanoma, metastases to the stomach were found in 2, the small bowel in 9, and the large bowel in 3. Gastric metastases typically appeared as target lesions. However, the morphology of secondary melanoma deposits to the small and large intestine varied significantly, target lesions being only one possible manifestation. Less common appearances of gut metastases were found in 4 patients. One presented atypically with matted loops of distal ileum resulting in prolonged stasis of barium in the affected areas. In 3 patients, infiltrative and stenotic lesions were found in the distal ileum, terminal ileum and cecum. One stenotic lesion of the distal ileum was accompanied by multiple small polypoid lesions more proximally, and the cecal lesion was ulcerated. Six of the patients presented with polypoid and, occasionally, ulcerated and multiple secondary melanoma deposits. Possible causes for variations in morphology are discussed.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
