title: An epidermoid cyst of the tendon.
abstract: An epidermoid cyst in the flexor superficialis tendon of the right middle finger of a child limited extension of the finger by preventing the distal gliding of the tendon at the inlet of the flexor tendon sheath. Full extension was regained by excising the tendon.
