Hemangioendothelioma of bone with pulmonary metastases: a 25-year course: report of a case.

: A unique case of hemangioendothelioma of bone arising in the right scapula of a 15-year-old boy is reported. The patient has been followed for over 25 years. After a symptom-free interval of 15 years, he developed a solitary pulmonary metastasis which was removed by left lower lobectomy. Five years later another metastasis was resected from his left upper lobe. During the subsequent five year period he has remained free of further evidence of metastases, attesting to the indolent course which may be taken occasionally by these malignant vascular tumors.
