맥관종의 병리조직학적 관찰

Abstract

The angiomas are frequent tumors encountered particularly in infants and children. It is probably not a true neoplasm but rather a remnant of fetal tissue and often referred as a type of hamartoma. This study was based on 448 cases that were examined and diagnosed as hemangiomas or lymphangiomas at the Department of Pathology. Seoul National University Hospital during a period of 20 years beginning from the year of 1960. A total of 448 angiomas was classified into 274 hemangiomas and 174 lymphangiomas. The hemangiomas were again divided into 128 capillary hemangiomas, 72 cavernous hemangiomas. 9 venous heman~ giomas, 16 mixed capillary-cavernous hemangiomas And 49 vascular malformations. One hundred and seventy four lymphangiomas were comprised of 60 cavernous Iymphangimas, 89 cystic lymphangiomas and 25 vascular malformations. Not a single case of capillary lymphangioma was seen. There were different features to distinguish cystic hygromas from cavernous lymphangiomas, and these tumors had specific site predilections. In capillary hemangiomas it was usual to find thick-walled vessels presumably representing feeding arteries and draining veins. They were not components of malformation in most cases. However, rarely anomalous arteriovenous malformation or other vascular malformation were seen around the main mass of capillary hemangiomas.
