Dermatofibrosarcoma protuberans in an adolescent: a case report and review of the literature

Classically, dermatofibrosarcoma protuberans (DFSP) is a disease of adults. The world literature revision shows that several pediatric cases have been reported so far; this might suggest that the number of infants with the condition might be larger than that estimated previously. Here, we report the 183rd case of histologically confirmed DFSP in young age. A 14-year-old white male patient came under our care for a slowly growing, pale brownish lesion on the neck skin. A biopsy specimen showed a DFSP. Subsequently, a wide surgery excision with 3 cm of resection margins including the underlying fascia was performed. To date, the patient has been in follow-up for 6 years without evidence of recurrent disease. The clinical features and treatment of DFSP diagnosed in childhood and adolescence reported in the published literature are reviewed to provide new insights about this rare entity. The aim is to emphasize the importance of biopsy for histologic evaluation in the cases that show a persistent or a large cutaneous plaque or nodule without pathognomonic clinical features that permit a clinical diagnosis. An accurate knowledge of the disease is the prerequisite for a wider recognition and appropriate treatment.
