GA-67 VISUALIZING METASTASES OF MALIGNANT-MELANOMA TO GASTRIC-CANCER

Metastases of one cancer to another coexisting neoplasm, whether it is malignant or not, in the same individual is extremely rare. Fewer tha n 100 cases have been described in the literature; the most frequent c ombination of this metastatic pattern has been bronchogenic carcinoma metastasizing to renal cell carcinoma. io the authors' knowledge, no c ase of malignant melanoma metastasizing to the inside of a gastric can cer lesion has been published. In our present case, it might be approp riate to think that an enlarged gastric cancer may have accounted for the avid accumulation of Ga-67. Nevertheless, the strongly speckled ac cumulation observed in the epigastrium may represent metastatic foci o f the melanoma within the gastric cancer.
