Abstract
Angiolymphoid hyperplasia with eosinophilia (ALHE) is a rare disease, currently considered a benign vascular proliferation of unknown etiology, and whose treatment is still unclear and challenging. Two women in their thirties consulted for itchy lesions of the right ear. Both presented with a reddish bleeding papulonodular infiltration of the auricle, with a nodule at the entrance to the external auditory canal in the first patient. Laboratory tests showed no abnormalities and in particular no hypereosinophilia or elevated serum immunoglobulin E. In both cases, histology of lesional skin showed vascular proliferation with thick-walled vessels lined by plump endothelial cells, protruding into the lumen, together with a mixed dermal inflammatory infiltrate consisting primarily of eosinophils and lymphocytes. A diagnosis of ALHE was made in both patients based on clinical and histological features. MRA revealed no underlying vascular malformation in both cases. Patients started treatment with 0.1% tacrolimus ointment twice daily. The pruritic sensation and bleeding had completely subsided within two weeks and the reddish infiltration and nodules had practically disappeared after two months of topical tacrolimus. Continuous applica...Continue Reading
