title: Multiple apocrine cystadenomas.
abstract: A 56-year-old man had approximately forty apocrine cystadenomas of the face and ears. Clinical examination and light microscopic findings were typical for apocrine cystadenomas. Electron microscopic findings showed an absence of annulate lamellae, thus differing from the only previously reported study. Review of the literature indicates that a large number of apocrine cystadenomas, such as on our patient, has not been reported previously.
