INTRODUCTION: The finger clubbing is most of the time associated with cardiovascular and pulmonary diseases. Pachydermoperiostosis also known as osteodermopathic syndrome, an hereditary disorder, is a rare cause of finger clubbing which might be difficult to diagnose in an incomplete form. EXEGESIS: We report a 36 years old black man presenting over many years polyarthralgias, broadening of fingers and clubbing of the fingers and toes extremities. This was mentioned on other family members. The physical examination was otherwise unremarkable. There were no skin thickening, no psoriasis-like and cardio-pulmonary disease features. These following exams were normal; Hemogram, fibrinogen, C reactive protein, rheumatoïd factor, serum calcium and phosphorus, thyroid hormones, growth hormone, chest X-ray, gastroduodenoscopy, electrocardiogram. The skeletal X-ray documented a widespread bone formation, a sacro-iliac osteosclerosis and interosseous ossifications betwen tibias and fibulas. CONCLUSION: Pachydermoperiostosis diagnosis was set up on 3 out of the 4 Borochowitz criteria. The absence of pachyderma defines this incomplete form. The osteoarticular manifestations lead mainly to differential diagnosis with the secondary hypertrophic osteoarthropathy and chronic inflammatory rheumatisms. The underlying pathogenic mechanism of this disease remains still unclear.
