Background: The angiolymphoid hyperplasia with eosinophilia (ALHE) is a sporadic vasoproliferative lesion of uncertain etiology involving the skin and the subcutaneous tissue. Occasionally, it involves also the large arteries compressing the near nerves. ALHE is commonly confused with Kimura's disease because of their clinical and histological similarities. Case Description: We report a case of a 52-year-old female suffering from a 6-month pain and paresthesias in the fourth and fifth finger of the right hand. The angiography showed a pseudoaneurysm in the proximal third of the right ulnar artery. A complete surgical excision of the vascular lesion was undertaken. The lesion forced the right ulnar nerve. The histopathological diagnosis deposed for ALHE. Conclusion: Up to now, literature has described 8 cases of ALHE involving the arteries, and only one case originating from the ulnar nerve. The authors report a case of a female with ALHE involving the ulnar artery that compressed the ulnar nerve. Clinical aspects, radiological features, surgical treatment, and operative findings are discussed reviewing the pertinent literature.

Abstract

Background: The angiolymphoid hyperplasia with eosinophilia (ALHE) is a sporadic vasoproliferative lesion of uncertain etiology involving the skin and the subcutaneous tissue. Occasionally, it involves also the large arteries compressing the near nerves. ALHE is commonly confused with Kimura's disease because of their clinical and histological similarities. Case Description: We report a case of a 52-year-old female suffering from a 6-month pain and paresthesias in the fourth and fifth finger of the right hand. The angiography showed a pseudoaneurysm in the proximal third of the right ulnar artery. A complete surgical excision of the vascular lesion was undertaken. The lesion forced the right ulnar nerve. The histopathological diagnosis deposed for ALHE. Conclusion: Up to now, literature has described 8 cases of ALHE involving the arteries, and only one case originating from the ulnar nerve. The authors report a case of a female with ALHE involving the ulnar artery that compressed the ulnar nerve. Clinical aspects, radiological features, surgical treatment, and operative findings are discussed reviewing the pertinent literature.
