A rare vasoproliferative lesion: angiolymphoid hyperplasia with eosinophilia of the hand

Abstract

Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare vasoproliferative lesion of uncertain aetiology, involving the skin and subcutaneous tissue. The predilection of the tumour-like lesion is for the head and neck region. Radical surgical excision is still regarded as the most effective treatment. We present the case of a 33-year-old female with ALHE of the right hand. Preoperative MRI and angiography demonstrated involvement of the fourth and fifth rays, with complete occlusion of the ulnar artery, and a small lesion at the level of the metacarpophalangeal joint of the index finger. Complete tumour excision could not be achieved without resection of the fourth and fifth rays. One year postoperatively, there were no clinical signs of recurrence. The patient refused any further invasive diagnostic and follow-up examinations. Angiolymphoid hyperplasia of the hand is a rare disease, and patients should undergo early surgical treatment to achieve complete excision of the lesion.
