The authors describe the ultrastructure of 2 dermatofibromas. Fibroblasts, the prevailing cellular component, showed different aspects related to a grading of their functional activity. No features of collagenogenesis were observed. Mast cells were also present, and nerve endings were found in subepidermal areas.
