Angiolymphoid hyperplasia with eosinophilia associated with arteriovenous malformation

Abstract

Conflict of interest: none declared. Angiolymphoid hyperplasia with eosinophilia (ALHE) is an uncommon benign disease, the pathogenesis of which has not been clarified. We present our data on a Korean patient with a painless subcutaneous nodule on the face, subsequently diagnosed as a unique case of ALHE associated with arteriovenous malformation (AVM). A 32‐year‐old man presented with a 3‐month history of a solitary, erythematous, subcutaneous, firm nodule at the nasal root. The patient did not have a history of trauma or injection to the site. On physical examination, the nasal root of the patient’s face showed a relatively well‐demarcated, erythematous, subcutaneous nodule measuring 15 × 10 mm (Fig. 1). It was slightly raised, and the centre of the lesion was pulsatile on palpation. There was no accompanying lymphadenopathy or any other systemic problems. A laboratory profile did not show any abnormal findings such as peripheral eosinophilia or a raised immunoglobulin level.
