Abstract

This is a report of papillary endothelial hyperplasia in a 9-year-old girl with a pilomatricoma showing bullous appearance. Histologically, papillary proliferation of endothelial cells was found within dilated lymphatic endothelium-lined vascular channels overlying a pilomatricoma. The endothelial cells covering the papillae were of a lymphatic endothelial cell nature proved by immunohistochemistry and electron microscopy. Abundant fibrous long-spacing collagen was observed in the connective tissue and fibroblasts within papillae.

摘要

这是一份关于一名9岁患有呈大疱状外观的毛发瘤的女孩的乳头内皮增生的报告。组织学上，在毛发瘤上方扩张的由淋巴管内皮衬里的血管腔内发现内皮细胞呈乳头样增生。免疫组织化学和电子显微镜证实覆盖乳头的内皮细胞具有淋巴管内皮细胞的性质。在乳头内的结缔组织和成纤维细胞中观察到大量纤维长间距胶原。
