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.

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.

Persistent blue nevus simulating melanoma.

We report a case of a persistent blue nevus that significantly extended beyond the scar of the original excision mimicking those clinical changes usually seen in melanoma. The histopathologic evaluation revealed a common blue nevus. The lesion was re-excised, and 10 months later a bluish macule appeared next to the surgical scar.
