Angiolymphoid hyperplasia (AH) was first described by Wells and Whimster in 1969 as a benign vasoproliferative pathology with a varied infiltrate of eosinophils, lymphocytes, and plasmatic cells. Clinical presentation has been described in the literature as small red-bluish nodules, less than 3 cm in diameter that can bleed in 25% of the cases and be pruritic and painful in 37% and 20% of the cases, respectively. Particularly, AH can appear in the ear; nevertheless, other regions have been affected, including the scalp, lips, tongue, orbit, muscle, and bone. Most of these cases have occurred in adults with an unknown etiology; however, an inflammatory process has been associated in approximately 20% with eosinophilia. No malignancy has been reported.
