He also had severe clubbing, with radiological evidence of periostosis
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.
in 1991 proposed diagnostic criteria for PDP i) major criteria: digital clubbing, periostosis, and pachydermia and ii) minor criteria: seborrhea, hyperhidrosis, folliculitis, arthritis or arthralgia, gastritis or gastric ulcer, acro-osteolysis, neurovegetative syndrome, hypertrophic gastropathy and cutis verticis gyrate.
PDP has 3 forms: complete form has periostosis and pachydermia, an incomplete form has abnormalities in bone and decreased or absent pachydermia and 'forme fruste' has marked pachydermia and minimum or decreased bone changes.
of bones and periosteal new bone formation stimulate the cortical thickening of the small bones of the hands and feet as well as of the distal ends of extremity long bones.
The presence of clubbing and radiographic evidence of periostosis of the tubular bones without underlying diseases correctly diagnosed PDP in this patient.
2) Diagnosis of HOA is made clinically based on the combination of digital clubbing and periostosis of tubular bones.
17) The clues for the differential diagnosis of HOA are digital clubbing and periostosis, which are not features of acromegaly.
Osteopatia hipertrofica: acropaquias, sinivitis, periostosis
INTRODUCTION: Pachydermoperiostosis (PDP), the primary or idiopathic form of hypertrophic osteoarthropathy (HOA), is characterized by pachydermia, clubbing of digits of both hands and feet, and periostosis.
Periostosis of distal ulna, radius, metacarpals, proximal and middle phalanges;
It is characterized by digital clubbing, pachydermia (thickening of the facial skin and/or scalp), and periostosis
(swelling of periarticular tissue and subperiosteal new bone formation).
