[A Tunisian case of pachydermoperiostosis].

Clubbed fingers are classically associated with chronic cardiac and pulmonary affection. Pachydermoperiostosis, a rarer aetiology, is a hereditary affection which is difficult to diagnose in its incomplete form. We relate a Tunisian case report. Our patient consulted for joint manifestations. The diagnosis of Pachydermoperiostosis was set up on 3 out of the 4 Borochowitz criteria. The osteoarticular manifestations mainly led to differential diagnosis with secondary hypertrophic osteoarthropathy. The underlying pathogenic mechanism of this disease still remains unclear.
