Two cases of lung carcinoma with osteoplastic bone metastasis.

Two cases of lung carcinoma with osteoplastic bone metastasis are reported. The bone roentgenogram of a 66-year-old woman with pleuritis carcinomatosa revealed multiple sclerotic changes in the right forearm, lumbar spine, and pelvis. Biopsy at internal fixation of the left humerus revealed metastatic adenocarcinoma with osteoplastic change. In a 77-year-old man with small cell carcinoma of the lung, after chemotherapy, osteoplastic bone changes were detected in roentgenograms. An ivory vertebra formation was seen in L1, L2 and L4, and bone scintigram showed, additionally, uptake in the ilium.
