Dermatofibrosarcoma protuberans of Darier and Ferrand

Individualized as a real anatomo-clinical entity in 1924 by Darier and Ferrand, the dermatofibrosarcoma protuberans is a rare cutaneous tumor of intermediate wickedness, which is characterized by its slow evolution, its local aggressiveness, a high power of recurrence and the rarity of metastases. Our casuistry lasts from february 2001 to october 2010 when 22 cases were supported. We distinguish 15 men and 7 women, whose average age was 42 years, ranging from 11 years to 64 years. Surgical excision of the tumor was large, with safety margins of 5 cm in 21 patients and 3 cm for a neck tumor. Of the 13 patients treated in first intention, none has recurred with a mean of 7 years. Other patients complain only one recurrence. None of our patients presented metastasis. The dermatofibrosarcoma mainly affects young adults with a slight male predominance. Its clinical diagnosis is difficult in the beginning stage, but he is more evident in the state phase. Histology, immunohistochemistry and the immunolabelling of the CD34 antigen, confirm the diagnosis. Different techniques can cover losses of substance caused by this mutilating surgery. Tumors are all of size greater than 5cm. Treatment is always surgical and must satisfy two principles: a wide margin of excision in the area and the sacrifice of a healthy anatomical barrier in depth

Principles of surgical treatment of malignant tumors skin

Malignant skin tumors are the most common human cancers in general, their incidence is steadily increasing due to longer life and behavioral habits, especially repeated sun exposure. We describe a series of 150 cases of skin tumors between October 1995 and January 2007. Most tumors are at the head. The age of the patients ranged from 10-75 years. Oncologic resection must meet specific margins for each type of tumor. The reconstruction is made after histological confirmation. Re We regret no serious complications postoperatively . One case of recurrence in a spinocellular carcinoma of the cheek, 1 year after treatment, is to report. If the vast majority of skin cancer have a good prognosis, their recurrent and multiple character and the fact that they affect more elderly population are so brittle they still represent a serious public health problem . Basocellular carcinomas are the most frequent tumors, they are slow growing, mostly local, which virtually never metastasize . Spinocellular carcinomas have a much more aggressive local development and can metastasize . Melanomas are the most dangerous malignant cutaneous tumors. Dermatofibrosarcoma protuberans never metastasis, its evolution is slow, his aggressiveness is local but has a tendency to relapse .The treatment of malignant skin tumors is surgical in the majority of cases. Oncologic resection must meet specific margins for each type of tumor. The cover is made after histological confirmation, it uses a skin graft or local flap coverage
