*Cyst lined by a bland bilayer. | |||
**Inner lining cells have: | |||
***Small, round nuclei - usu. basal. | |||
***Moderate pale/greyish cytoplasm. | |||
***No apocrine snouts - flat surface. | |||
**Outer lining cells - spindled. | |||
***May be difficult to see. | |||
DDx: | |||
*[[Apocrine hidrocystoma]] - have apocrine snouts; surface is ''not'' flat. | |||
*Cystadenoma - has epithelial proliferation. | |||
