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

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.

Reflex sympathetic dystrophy and early damage of carpal bones.

A 56-year-old woman presented with changes characteristic of the reflex sympathetic dystrophy syndrome (RSDS) but also frank synovitis of the left wrist, an elevated ESR and early damage of the left carpus on radiographs, suggesting septic arthritis. A dynamic scan showed changes characteristic of RSDS. A sample of synovium and bone from the wrist showed non-specific inflammation with partial destruction of cartilage by synovial pannus and involvement of subchondral bone by the inflammatory process.
