Chimney sweeps' carcinoma
Chimney sweep's cancer, also called Soot wart, is a squamous cell carcinoma of the skin of the scrotum. It has the distinction of being the first reported form of occupational cancer, and was initially identified by Percivall Pott in 1775.〔General Surgery Lecture notes, H.Ellis, Wiley Blackwell, 12th edition〕 It was initially noticed as being prevalent amongst chimney sweeps.
==Description==
It is a squamous cell carcinoma of the skin of the scrotum. It was first detected in 1775, where it affected chimney sweeps in their late teens and early twenties who had been in contact with soot since their early childhood. It was proposed that sweat running down their bodies had caused soot to accumulate in the rugae of the inferior surfaces of the scrotum. Warts caused by the irritation from soot particles, if not excised, developed into a scrotal cancer. This then invaded the dartos, enlarged the testicle and proceeded up the spermatic cord into the abdomen where it proved fatal. Irritation was discounted when it was experimentally shown in 1922 that an ingredient of coal soot was a carcinogen.
