Kaposiform hemangioendothelioma of paranasal sinus.

Kapossiform hemangioendothelioma (KHE) of the paranasal sins (PNS) is a rare cause of recurrent epistaxis. To date, only two cases of PNS KHE have been reported in the literature, both occurring in the pediatric population. The case presented here appears to be the first case of PNS KHE occurring in an adult. A 46-year-old white female presented with progressively worsening unilateral recurrent epistaxis. Diagnostic histopathology confirmed it to be KHE. After a detailed workup, the tumor was completely excised en bloc (medial maxillectomy; anterior and posterior ethmoidectomy) via a lateral-rhinotomy approach. Complete excision of the tumor with clear margins offers the best results.
