Unusual features of nevocellular nevi

The microscopic examination of benign pigmented nevi is often cursory, with the result that interesting secondary changes within those nevi arc sometimes disregarded. Because the descriptions of these histologic variations in nevi are scattered through the literature of the last 30 years, it seems timely to review them. Age‐related changes (Maize & Foster 1979), the epidermal architecture of nevi (Bentley‐Phillips & Marks 1976) and general aspects of melanocytic nevi (Bhawan 1979) have all been reviewed in recent years and will not be considered further.
