Abstract:
Epithelioid hemangioendothelioma (EH) is an unusual vascular neoplasm characterized by proliferation of endothelial cells with epithelioid morphology. It has an indolent course, with the potential for recurrence, but rarely metastasizes. The common locations include soft tissue, skin, viscera and bone. We present an unusual case of EH in the nasal cavity and describe the clinical characteristics, histopathologic findings, differential diagnosis and management. The 25-year-old male patient initially presented with an 8-month history of intermittent epistaxis. Nasal endoscopy revealed a vascular tumor involving the nasal cavity. The tumor was excised and the final histopathologic diagnosis was consistent with EH. EH in the head and neck is extremely rare. Wide excision is the treatment of choice, and regular follow-up is suggested due to the potential for recurrence. Definitive diagnosis depends on histopathologic and immunohistochemical features.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
