RESUMO
Intravascular papillary endothelial hyperplasia (IPEH) is an unusual reactive lesion of vascular origin, which rarely occurs in the oral cavity. Pathogenetically, is it divided into true, mixed and extra‑vascular types. We report a case of extra‑vascular IPEH of the lower lip in 54‑year‑old female patient. Patient gives history of trauma 4 months back with lesion developing at the site to trauma. The lesion was 3 cm × 4 cm in size with soft to firm in consistency. Histologically, it is characterized by an exuberant papillary endothelial cell proliferation toward the lumen of an enlarged blood vessel from the area of an organizing thrombus. The lesion was surgically excised under local anesthesia. The patient was followed for 1‑year with no evidence of recurrence. This paper discusses the various aspects of IPEH of the oral cavity such as pathogenesis, clinical features, histopathology treatment, and prognosis.
