Abstract:
Intravascular papillary endothelial hyperplasia (IPEH) is a rare benign proliferation of intravascular endothelial cells. However, IPEH can be easily mistaken for an angiosarcoma, thus differential diagnosis is very important to avoid over-treatment. We report the case of a 22-year-old man who presented with small lobulating mass in nasopharynx. Computed tomography showed about 4 cm homogenous mass in the nasopharynx without extension into soft tissues. Complete surgical excision was done and biopsy during operation showed distended vessels and numerous papillae consist of endothelial cells lining a hyaline core. At follow up, no other complications were observed. Thus we present the case and a review of the literature.
