title: Is confluent and reticulated papillomatosis without papillomatosis early or late stage of confluent and reticulated papillomatosis?
abstract: The histologic findings of confluent and reticulated papillomatosis include papillomatosis, hyperkeratosis, and minimal or no acanthosis. We present a patient with the clinical findings of confluent and reticulated papillomatosis who responded dramatically to azithromycin, but histologic examination did not reveal papillomatosis. We observed invagination of basket-weave hyperkeratosis through the epidermis. We considered this finding may give a clue for the diagnosis of confluent and reticulated papillomatosis.
