Metastatic bone cancer are most frequently seen in vertebrae, pelvis, rib, skull and femur etc, but rarely seen in the peripheral bones below the elbow or the knee joint.381 cases of metastatic bone cancer were diagnosed radiologically from March 23rd. 1962 to January 31th. 1968, at the National Cancer Center Hospital.Among them, 7 cases were diagnosed to have bone metastasis in hand and foot bone.Three cases which were very interesting in diagnosis and clinical course were presented.Case 1. A man, fifty-six years old; bone metastasis of the finger.Case 2. A woman, seventy-three years old; wide-spread bone metastases of the hand.Case 3. A woman, fifty years old; metastases of the metatarsal bones.In case 3, open biopsy was not done, but aspiration needle biopsy was done for the exact diagnosis of the metastatic bone cancer and cancer cells could be seen in the May-Giemsa stained specimen.Moreover, the cancer cells were recognized from the neighbouring bone which showed Sudeck's bone atrophy-like shadow and were very difficult to be diagnosed as bone metastases.Therefore, bone metastases of all metatarsal bone were diagnosed very quickly and easily, and early radiation therapy was successfully performed.
