Hidrocystoma on low magnification shows characteristic thin-walled, dermal-based, empty cystic spaces image.

Hidrocystomas can be multilocular. A thin layer of bland-appearing apocrine epithelium image lines the cystic lumina.



  • Cystadenoma (apocrine and eccrine)

  • Apocrine gland cyst

  • Sudoriferous cyst

  • Moll gland cyst

  • Papillary apocrine gland cyst


  • Cystic, dome-shaped, translucent papules with bluish hue commonly found on the eyelids


Eccrine vs. Apocrine Hidrocystomas

  • Most, if not all, hidrocystomas are now considered to be of apocrine origin

  • Apocrine hidrocystoma

    • Usually multiloculate

    • Cytoplasmic projections into cyst cavity: “Decapitation” secretion present

  • Eccrine hidrocystoma

    • Usually unilocular

    • No “decapitation” secretion

    • Considered to be retention of dilated eccrine duct or gland, and not a true cyst
