While well-developed plaques that are clinically diagnostic for mycosis fungoides are usually intensely pruritic, less characteristic ones typically are not, and the development of pruritus in such lesions is a sign of progression towards mycosis fungoides. Depending on whether the lesions involve up to 10% of the body surface or involve 10% or more of the body surface, such cases are classified as stage IA or IB, respectively. Many cases remain at these stages for many years or decades without further progression.
