Complete form of pachydermoperiostosis: a case report

Pachydermoperiostosis is a primary form of hypertrophic osteoarthropathy, which presents with pachydermia, digital clubbing, and radiologic periostosis. Pachydermoperiostosis occurs owing to mutations of the gene encoding for 15-hydroxyprostaglandin dehydrogenase (15HPGD). Clinical manifestations of PDP are thought to relate to excessive collagen formation and dysregulation of matrix proteins because of fibroblastic hyperactivation. We present a very rare case of the complete form of pachydermoperiostosis in a young Indian male.
