A Case of Angiolymphoid Hyperplasia with Eosinophilia / 대한이비인후과학회지

ABSTRACT

Angiolymphoid hyperplasia with eosinophilia is a disorder of the skin and subcutaneous lesion of unknown cause. It is characterized by painless, vascular tumor-like nodules of various size, primarily affecting the head and neck region. The histological hallmark of angiolymphoid hyperplasia with eosinophilia is a benign angiomatous or angioma-like proliferation within the background of the stroma, which is heavily infiltrated by lymphocytes and eosinophils, and includes lymphatic follicles with prominent germinal centers. The authors have recently experienced a case of angiolymphoid hyperplasia with eosinophilia in a 29-year old male who had painless and enlarging nodules in the nasal cavity and the buccal mucosa for a year. We present this case with the review of literatures.
