Several studies of dermatofibrosarcoma protuberans (DFSP) reveal an almost equal sexual distribution or a slight male predominance. In a large study of 902 patients with DFSP conducted by Rutgers et al, 514 (57%) patients were male and 388 (43%) patients were female. [12] A study based on 405 DFSP cases from the Swedish National Cancer Registry between 1990 and 2005 shows a very small difference in annual incidence of male (4.4 cases per million) versus female (4.0 cases per million). [11] However, a larger cancer registry study of 2885 cases reveals females might have a slightly higher incidence of DFSP, 4.4 cases versus 4.2 cases per million population per year. [8]
