| Abstract: | We report the case of an 11-year-old male patient with a histopathological andimmunohistochemical diagnosis of dermatofibroma with an atypical clinicalpresentation on the right forearm. Although dermatofibroma is considered abenign skin tumor, some of its differential diagnoses, such asdermatofibrosarcoma protuberans and malignant fibrous histiocytoma, are trulyaggressive. Lesions with atypical clinical aspects and topology associated withspecific histopathological variants are some of the criteria for complete tumorexcision. |
