RECURRENT NEVUS

recurrent nevus


The recurrent nevus is the return of a nevus after only partial surgical removal--usually via a shave biopsy. The recurrent nevus commonly has atypical clinical and histologic features. The key point here is to distinguish it from a melanoma. Just because the pathology of the partial removal was benign does not mean that the current lesion is not malignant--either through evolution or because of initial sampling error.

Clinical

Usually, there is a white circular scar a pigmented lesion in the center. The pigmentation is often irregular in shape or color.

Treatment

A complete excision should be done.

This pigmented lesion was NOT a recurrent nevus. Instead, it was a melanoma in situ occurring in a previously shave-biopsied nevus.
