Metastases of carcinoma in the pagetic bone. A report of two cases.

ABSTRACT

Two men, aged 68 and 77 years, had metastases of carcinoma in pagetic bones. These cases were initially diagnosed clinically as Paget's sarcoma. Roentgenograms, scintigrams, and bone puncture biopsy specimens (BPBs) of the right scapula and the sacrum, respectively, showed only Paget's disease. However, an additional BPB obtained with the aid of computed axial tomography (CAT) revealed the presence of metastases of lung carcinoma in the right scapula and of a carcinoma of probable prostatic origin in the pagetic sacrum in the other. The observations testify to the usefulness of CAT-directed BPB when Paget's sarcoma is suspected, especially in cases located in the scapula, pelvis, or spine.
