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. This case of a persistent blue nevus with an unusual clinical presentation and a benign clinical course highlights the fact that the clinical markers commonly used to identify melanoma in pigmented lesions will not always accurately diagnose melanoma.

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. 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.
