Female urethra (blue, distal) and bladder

Microscopic (histologic) description
  • Urothelium
    • Basal layers composed of either low columnar or cuboidal cells, followed by several layers of polyhedral cells
    • Most superficial composed of round, dome shaped umbrella cells that are occasionally multinucleated and flattened according to amount of distention
  • Nonkeratinizing squamous epithelium
    • Composed of multiple layers
    • Divided in zones according to cell shapes; cuboidal (deepest), polymorphous (middle), squamous / flattened (superficial)
  • Periurethral glands
    • Periurethral (Skene) glands: lined by columnar or cuboidal epithelium with surrounding connective tissue and smooth muscle (Ann Anat 2002;184:341)
    • Minor vestibular glands (Littré glands): tubuloacinar-mucinous glands with uniform, pale eosinophilic to clear cytoplasm and basally flattened nuclei in penile urethra (Mills: Histology for Pathologists, 4th Edition, 2012)
