| Abstract: | We report the case of an 11-year-old male patient with a histopathological and
immunohistochemical diagnosis of dermatofibroma with an atypical clinical
presentation on the right forearm. Although dermatofibroma is considered a
benign skin tumor, some of its differential diagnoses, such as
dermatofibrosarcoma protuberans and malignant fibrous histiocytoma, are truly
aggressive. Lesions with atypical clinical aspects and topology associated with
specific histopathological variants are some of the criteria for complete tumor
excision. |
