Pachydermoperiostosis and bladder cancer

Pachydermoperiostosis or the Touraine-Soulente-Golé syndrome is a rare monogenetic disorder characterized by pachydermia, periostosis and digital clubbing accounts for approximately 3∼5% of all patients with hypertrophic osteoarthropathy. Missense mutations in SLCO2A1 and HPGD genes could plausibly underlie the pathogenesis of pachydermoperiostosis. Patients have usually a favorable outcome with very few cases associated with cancer. Herein, we report the first case of a patient with pachydermoperiostosis associated with bladder cancer
