Background. Angiolymphoid hyperplasia with eosinophilia is a benign vascular proliferation that usually affects the head and neck region.
Method. An 89-year-old man who had a squamous cell carcinoma on the posterior aspect of one ear developed lesions of angiolymphoid hyperplasia with eosinophilia on the anterior aspect of the same ear.
Results. After surgical treatment of the malignant neoplasm, the lesions of angiolymphoid hyperplasia with eosinophilia disappeared spontaneously.
Conclusions. Damage to the vasculature of the ear by the malignant neoplasm or the release of angiogenic factors by the same neoplasm is a plausible explanation for the development and eventual resolution of the vascular proliferation
