Multiple connective tissue nevi

Connective tissue nevi are uncommon, and rarely suspected clinically because of their diverse morphologic presentations. Histologically, we define connective tissue nevi as discrete areas within the papillary or recticular dermis where a clear predominance or depletion of collagen, elastin, or glycosaminoglycans may be found. We report a case of multiple connective tissue nevi with a predominance of dermal collagen deposition, without extracutaneous findings and no family history of connective tissue nevi. These lesions can thus be classified as being of the eruptive collagenoma type.
