title: [Clubbed fingers, hourglass nails].
abstract: Clubbing was the main clinical symptom in a 27 year old male patient. There was no clubbing in other family members. Secondary clubbing was excluded by clinical findings, laboratory, x-ray of the chest, electrocardiography, pulmonary function test, blood gas analysis, colonoscopy, x-ray of hands and feet and capillary microscopy. Final diagnosis was idiopathic clubbing.
