[Malignant tumors of lymphatic vessels in children].
Lymphangiosarcomas were found in 5 out of 82 observations of vascular malignant tumours in children, according to the data of the pathological department of Children's Clinical Hospital No. 1, for 60 years. Differential diagnosis of relapsing lymphangiomas and rarely found malignant lymphangioendetheliomas presents considerable difficulties for morphologists because of poorly manifest cell polymorphism in the primary node of neoplasia and the presence of areas of lymphangioma and malignant hemangioendothelioma among fields of lymphangiosarcoma. Cytological studies assist in specification of the degree of malignancy and histologenesis of the neoplasias.
