Introduction:
The pachydermoperiostosis (PDP) or primitive hypertrophic osteoarthropathy (HOA) is a rare hereditary disease.
Case Record:
We report a 22-year-old man born to consanguineous marriage who presented presented with PDP. This patient disclosed an arthropathy, a clubbing, a diffuse periostosis, and a pachyderma of the hands, the feet and the forehead. All the examinations that were performed to look for an etiology remained negative. Diagnosis of PDP was considered and the patient treated with colchicine.
Discussion:
We discuss the diagnostic issues raised by PDP, especially with the secondary HOA and chronic inflammatory rheumatisms.
