Pilonidal sinus disease

Pilonidal Sinus Disease is a debilitating skin condition which occurs principally in the natal cleft of the sacrococcygeal region. It presents itself as a subcutaneous cyst or abscess, most frequently in white patients, typically in the late teens to early twenties, who are otherwise fit and healthy. The average age of presentation is 21 years for men and 19 years for women, and rarely occurs after age 45. [1, 2] Incidence of pilonidal disease in the general population is about 26 per 100,000 population (0.026%), with a male preponderance. It occurs in the ratio of about 3 or 4:1. In children, however, the ratio is the opposite occurring in 4 females for each male it afflicts.
