Nevi of connective tissue A reappraisal of their classification

Abstract

Nevi of connective tissue may be conveniently divided according to clinical and pathologic presentations into two types, namely, the adventitial and the reticular. Nevi of adventitial connective tissue are usually small and situated on the extremities. They are characterized by accumulations of fibroblasts and apposition of collagen around adnexa and vessels. Nevi of reticular connective tissue are usually situated on the trunk. They consist of faulty distributions and amounts of collagen bundles, elastic fibers, or proteoglycans.
