Surgical treatment in 12 cases with mediastinal lymphangioma and hemangloma,which accounted for 2. 88% of a total of 416 mediastinal tumors is reported.Eight of the cases presented no specific clinical features and the other 4 had mediastinal shadows on routine chest films. Nine of the 12 of them had lesions located in the anterosuperior mediastinum and 3 in the Posterior. Accurate diagnosis was not established preoperatively in 10 cases. Complete surgical removal was accomplished in 8 cases of cystic lymphangioma or cavernous angioma, while the other 4 patients with mediastinal fibroangiolymphangioma had incomplete excision because of involvement of the neighbouring organs and tissues having the residual cyst wall closed down as much as possible. Histological diagnosis consisted of 4 cystic lymphanglomas, 4 cavernous hemangiomas and 4 fibroangiolymphangiomas. There was no recurrence after excision with a period of following up for 1 to 23 years.
