[edit] Discussion of Testicular epidermoid cyst

  • Uncommon benign tumors of germ cell origin that are also known as keratocysts,
  • Epidermoid cysts range in diameter from 1 cm to 3 cm.
  • They are nontender and usually palpable.
  • Age at presentation is typically 20 to 40 years.
  • If the diagnosis of an epidermoid is suspected at preoperative US, the lesion can be enucleated and frozen sections obtained to confirm the diagnosis. This procedure avoids the need for orchiectomy.
