Differential diagnosis
Keratinous cyst (epidermal inclusion cyst)

  • No dermal appendages
Hidrocystoma (sudoriferous cyst)

  • Thin walled transparent vesicles at margin of lid, lined by atrophic cuboidal or flattened epithelial cells containing watery fluid or with an empty lumen ("sudoriferous" means carrying or producing sweat)
  • Lined by 1 - 2 layers of flattened cuboidal cells
Apocrine hidrocystoma
  • Lined by double layer of columnar cells with eosinophilic cytoplasm, papillary projections and apocrine snouts
