Angiolymphoid hyperplasia with eosinophilia associated to a squamous cell carcinoma of the ear.
BACKGROUND
Angiolymphoid hyperplasia with eosinophilia is a benign vascular proliferation that usually affects the head and neck region.


METHODS
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.
