A 9 year old child was operated upon for a very vascular tumor of the right piriform sinus, signs of which had been present at birth. Histopathologic and ultrastructural examinations showed the lesion to be composed of both endothelial and pericytic elements, suggesting the diagnosis of a cellular hemangioma. This tumoral variety, particularly rare in the larynx, has been distinguished from the group of hemangiopericytomas described by Stout and Murray, not only by its usual congenital character and course but also by its specific structure.
一名9岁儿童因右侧梨状窦的一个血管极为丰富的肿瘤接受了手术，该肿瘤的症状在出生时就已出现。组织病理学和超微结构检查显示，该病变由内皮细胞和周细胞成分组成，提示诊断为细胞性血管瘤。这种肿瘤类型在喉部特别罕见，它不仅因其通常的先天性特征和病程，还因其特殊结构，与Stout和Murray所描述的血管外皮细胞瘤组有所区别。
