Dermatofibroma has been classified into "benign skin tumors" in traditional dermatology textbooks. However, it has been known that dermatofibroma could develop from a very small inflammation such as an insect bite and injection. Clinically, hypertrophic scars tend to develop after extirpation of dermatofibroma. Thus, we have speculated that dermatofibroma has the same developmental mechanisms as fibroproliferative disorders of the skin including hypertrophic scars and keloid. Their clinical appearance may differ in strength and onset time of inflammation. Thus, we have analyzed some clinical cases and compared these features histologically.
