The dysfunctional foreskin.

Although important, the foreskin is not absolutely essential to penile function. Dysfunction is common and a cause of considerable morbidity, and is sometimes associated with mortality from squamous cell carcinoma (SCC). Penile dermatoses herald, complicate or cause preputial dysfunction. Their effective diagnosis and management reduces morbidity and possibly mortality. Medical treatment has its limitations and circumcision is often required.
