Hemangiosarcoma: report of 5 cases / 中华普通外科杂志

ABSTRACT

Objective To investigate the clinicopathological and immunophenotype features of hemangiosarcoma.Methods The clinical,pathologic features of 5 cases of hemangiosarcoma,admitted in our hospital during 2006-2014,were retrospectively analyzed.Results Tumors were located in the spleen (n =3),liver(n =1),scalp(n =1),tumor metastasis to the lung or marrow was found in 4 cases.Preoperative misdiagnosis as lymphoma,cavernous haemangiomas or parasite cyst was suggested by ultrasonography or CT,and final diagnosis was established by typical pathological pictures.CD34,CD31,FⅧ and Vim were positive in tumor cells while CK,EMA were negative.The survival time of the patients receiving resection only was 2 days,4 months and 13 months.The survival time of the patients receiving operation plus chemotherapy was 6 months or 48 months.Conclusions Hemangiosarcoma is a rare and aggressive malignant tumor of soft tissue which has poor prognosis.The additional survival benefits provided by chemotherapy remains unproven.
