SOLITARY ADENOCARCINOMA METASTASIS MIMICKING SARCOMATOUS DEGENERATIONIN PAGETS-DISEASE

A rare case of mucinous adenocarcinoma presented as a solitary, metast atic deposit to a region of Paget's disease within the peripheral skel eton. Historical, physical, radiographic, and scintigraphic findings w ere indistinguishable from those of sarcomatous degeneration arising f rom pagetoid bone, This case supports the idea that when a painful, os teolytic lesion is discovered within a region of Paget's disease, bone scintigraphy has greater value for disclosing potential multifocal or multicentric disease than for providing etiologic specificity for the principal lesion.
