Abstract

BACKGROUND:

Meyerson phenomenon is an uncommon clinical condition that is characterized by an eczematous halo surrounding a preexisting melanocytic nevus and numerous other lesions. The etiology of this condition is unknown. We suggest that the mechanism is due to the interaction between CD4 T lymphocytes and increased expression of intercellular cell adhesion molecule 1 (ICAM-1).

OBJECTIVE:

This article provides a concise overview of Meyerson phenomenon.

METHODS AND RESULTS:

We present the case of a 37-year-old female with an inflamed nevus located on her thigh from no evident cause. Her condition resolved with surgical excision of the nevus. Histopathology of the specimen demonstrated spongiosis and lymphocytic infiltrate with eosinophils, which confirmed the diagnosis of Meyerson phenomenon.

CONCLUSION:

Meyerson phenomenon can resolve spontaneously or with treatment of either topical steroids or surgical excision. The main concern with benign lesions presenting with inflammation is malignant transformation; thus, clinicians need to be more aware of Meyerson phenomenon.
