Two cases of confluent and reticulated papillomatosis with an unusual location.

Sir, Confluent and reticulated papillomatosis (CRP) is a rare dermatosis of unknown origin characterized by hyperpigmented, confluent papules. The sites of predilection are the neck, inter-mammary area and abdomen (1). Rarely, CRP develops at the other sites, such as the knee, elbow, hand, and antecubital and popliteal fossae (2, 3). We describe two rare cases of CRP that developed at the elbow and popliteal fossae.
