title: Angiosarcoma of the liver in childhood: a clinicopathologic and follow-up study of 10 cases.
abstract: The clinical, morphologic, and follow-up findings in 10 cases of childhood hepatic angiosarcoma are reported. Six patients were female and four were male. The age range was 18 months to 7 years, with a mean of 3.7 years. The usual presenting feature was an abdominal mass, with or without associated symptoms. The histologic pattern of childhood hepatic angiosarcoma typically consists of large hypercellular whorls of spindled sarcoma cells intermingled with bile ducts, vessels, and collagen. Factor VIII staining of tumor cells is focal, cytoplasmic, and weak in character. Intracellular eosinophilic, PAS-positive globules are present in most cases and may be abundant. The prognosis is poor; follow-up available in seven cases showed only one to be alive 32 months after diagnosis. The remaining six patients had died 0-27 months (mean 10 months) after diagnosis.
