%X BACKGROUND: Darrier-Ferrand dermatofibrosarcoma (DFSC) is the most common cutaneous sarcoma. It generally affects subjects with an average age of 40 years, without gender or race predominance. It is a tumour characterised by a slow evolution and local aggressiveness. The reasons for consultation are pain, pruritus or rapidly progressive evolution. There are no specific imaging studies for this tumour. The diagnosis of certainty is based on immunohistochemistry with positive CD34 labelling. Treatment is surgical based on wide excision.
METHODS: This is an observation of a patient operated in our department for the initial diagnosis of cutaneous leiomyosarcoma of the right flank that rapidly increased in volume to 10cm in six months. A large fasciocutaneous excision was performed. The postoperative course was simple.
CONCLUSIONS: In our patient, this lesion occurred on an old burn scar. This notion of skin trauma preceding the appearance of DFSC is reported in 10 to 20% of cases. The rapid increase in volume was the reason for consultation. The diagnosis of DFSC could only be made on definitive analysis of the surgical specimen, which showed positive immunostaining for CD34. The occurrence of metastases, although rare, confers a survival of no more than two years. The prognostic factors depend on the quality of the surgical excision, the presence of metastases and certain locations (head, neck), which make the surgery particularly mutilating. Only long-term monitoring attests to definitive cure, given the frequency of recurrence.
CONCLUSIONS: DFSC is a rare and slowly evolving tumour. Wide surgical excision should be attempted in most cases. In inoperable cases, the use of targeted therapies (IMATINIB) has led to complete cures in some cases.
