Microscopic features of lichen sclerosus et atrophicus in acrochordons: a clue to the cause of lichen sclerosus et atrophicus?

BACKGROUND The cause of lichen sclerosus et atrophicus (LSA) is unknown, but on the penis it is associated with chronic occlusion, that is, phimosis. Microscopic changes of LSA were seen unexpectedly in two acrochordons. OBJECTIVE Our purpose was to further characterize this phenomenon. METHODS A total of 449 acrochordons examined in our histopathologic… CONTINUE READING
