[Apocrine cystadenoma. About 3 observations with one balanic localization (author's transl)].

Description of three apocrine cystadenomas: two of the face and scalp and one of the glans (urethral meatus and left anterior surface of the navicular fossa) with no bibliographical precedent. From a clinico-histological standpoint the importance of objective data which make possible the clinical diagnosis is stressed allowing light microscope differentiation from eccrine hydrocystoma. The histogenesis is exposed and it appears convenient to name (eccrine or apocrine) cystadenoma the authentic cystic adenoma (among the organoid hamartoma of the cutaneous appendages, while reserving the term (eccrine or apocrine) hydrocystoma for glandular cysts. Due to the esthetic and occasionally functional repercussion, surgical excision is indicated.
