[A case of angiosarcoma of pelvis with pulmonary metastases which responded to paclitaxel].

A 60-year-old man was admitted to our hospital complaining of back pain and bloody sputum. Chest CT scan showed characteristic multiple small nodules with central dense opacity and surrounding faint opacity, suggesting lesions with hemorrhage. Bone scintigram and MRI revealed multiple osteolytic lesions in pelvis and lumbar spine. Biopsy of the bone lesion established a diagnosis of angiosarcoma. Chemotherapy with paclitaxel and palliative radiotherapy for the bone were initiated. Pulmonary metastases dramatically diminished after 4 courses of paclitaxel treatment. After eight weeks, the tumor recurred. Salvage chemotherapy of weekly administration of docetaxel yielded limited effects. The patient died of cancer one year after treatment initiation.
