Definition / general
  • Condition in which the foreskin cannot be retracted due to a small orifice
Etiology
Clinical features
  • Smegma (desquamated epithelial cells, debris) may accumulate, causing secondary infections and possibly carcinoma
  • Must liberally sample foreskin to rule out other pathology
  • Most young boys who present with tight foreskins have physiologic phimosis, which will generally resolve by adolescence with proper foreskin hygiene (Can Fam Physician 2007;53:445)

Microscopic (histologic) description
  • Fibrosis of lamina propria associated with nonspecific lymphocytic and lymphoplasmacytic infiltrate

  • May be associated with underlying lichen sclerosus
  • May be associated with epithelial hyperplasia, dysplasia, penile intraepithelial neoplasia or occult early invasive carcinoma
