Young man presenting with clubbing - A case-based evaluation

Clubbing is the bulbous enlargement of the distal segment of digits. It is known to be associated with several cardiological, gastrointestinal, pulmonary, neoplastic, infectious, and endocrinological disorders. Rarely clubbing may not associate with any underlying pathology despite presenting in a later stage. Here we report a case of a 26- year- old man who presented with a history of recent onset of clubbing. Following extensive evaluation we were unable to find a possible etiology.
