Angiolymphoid Hyperplasia with Eosinophilia (ALHE) of the Oral Cavity: a Case Report

ABSTRACT

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare benign vascular lesion that is characterized by proliferation of small to medium-sized vascular structures lined by histiocytoid or epithelioid endothelial cells and often accompanied by an inflammatory infiltrate comprising lymphocytes, plasma cells and eosinophils. A 34-year-old man without any generalized systemic conditions presented with a slowly enlarging painless swelling in the buccal area. An excisional biopsy was conducted and the diagnosis of Angiolymphoid hyperplasia with eosinophilia was confirmed. We report a case of angiolymphoid hyperplasia with eosinophilia of the buccal area in oral cavity and review the previously reported cases and literatures of angiolymphoid hyperplasia with eosinophilia.
