Nasal kaposiform hemangioendothelioma: a rare disease in a rare location-a review article with a case report.

Kaposiform hemangioendothelioma is a rare vascular tumor of endothelial origin that occurs during the first decade of life. It is locally aggressive, with a tendency for local invasion and spread to regional lymph nodes. It presents as tender, expanding plaques, nodules, papules, or telangiectasias and is most commonly located in the retroperitoneum and skin; however, involvement of the head and neck region is uncommon. Herein, we report an unusual case of kaposiform hemangioendothelioma in a 59-year-old woman who presented with a several-month history of right-sided nasal obstruction and epistaxis. Contrast-enhanced computed tomography revealed an enhancing mass originating from the right inferior turbinate. The patient underwent endoscopic excision of the endonasal mass with any postoperative complications.
