• What is to our knowledge the first apocrine cystadenoma reported on the penile shaft is described. Of 96 previously reported apocrine cystadenomas, more than 90% were located on the face, ears, or scalp; the remainder occurred on the chest, axilla, or prepuce. Apocrine cystadenoma should be considered in the differential diagnosis of solitary blue, gray, or flesh-colored cystic nodules in those areas.
