title: Acute calcific tendinitis of the flexor pollicis longus in an 8-year-old boy.
abstract: Calcific tendinitis is a common source of musculoskeletal pain in adults; however, it is rarely encountered in children. Calcific tendinitis is the most commonly encountered manifestation of hydroxyapatite deposition disease, in which calcium hydroxyapatite crystal deposition occurs in tendons. It may cause acute or chronic pain, or may be entirely asymptomatic. We describe a case of acute calcific tendinitis of the flexor pollicis longus tendon in an 8-year-old boy, who initially presented to our department for workup of a mass felt along the volar aspect of the right wrist.
