Pachydermoperiostosis (PDP) is a rare disorder characterized by skin thickening (pachydermia
), digital clubbing, proliferation of periosteum (periostitis) with subperiosteal new bone formation, and an excess of affected males.
It has also been called scirrhous carcinoma, pachydermia
and Acarcine eburnee by various authors.4
A benign organic lesion of the larynx includes noninfective and nontraumatic laryngeal disorders; such mass-producing lesions of the larynx involves mainly chronic laryngitis, vocal cord polyp, vocal cord nodule, Rienke's edema, and contact pachydermia
. Acute laryngitis and tubercular laryngitis are mainly the infective lesions of the larynx.
Stroboscopy revealed pachydermia
laryngitis with severe tissue redundancy that prevented vocal fold visualization (figure 1).
Clinical presentation is classified into the complete form (pachydermia
, clubbing, and periostosis), the fruste form (prominent pachydermia
with minimal skeletal changes), and an incomplete form which has no pachydermia

There was thickening of forehead folds with evident pachydermia
. The other notable features were palmo-plantar hyperhidrosis and cutis verticis gyrata.

, the thickening and coarsening of facial features, the clubbing of digits, hyperhidrosis, edema in the lower legs, arthritis both with and without joint effusion, and periosteal reaction of the long bones.

INTRODUCTION: Pachydermoperiostosis (PDP) is a primary hypertrophic osteoarthropathy, characterized by various clinical expressions with the involvement of digital clubbing, pachydermia
, seborrhoea, periostosis and arthritis or arthralgia.
