Dermatofibrosarcoma protuberans with onset in early childhood: a case report

Dermatofibrosarcoma protuberans is a tumour that grows locally, infiltrating the subcutaneous tissue; it is uncommon in children. We report the case of a 27-year-old man who had had such a lesion from the age of 3 years, and it had enlarged during his lifetime. A wide local excision with margins of 3.0 cm was performed, but the lesion was not entirely removed. This is a new report of infantile dermatofibrosarcoma protuberans, and this case reflects the need for Mohs micrographic surgery.
