Pachydermoperiostosis, a rare genetic disorder, presents with skin thickening and bone changes, primarily affecting men. This case report details a typical presentation and emphasizes distinguishing it from secondary causes like lung tumors.

Area of Science:

  • Dermatology
  • Genetics
  • Radiology

Background:

  • Pachydermoperiostosis (primary hypertrophic osteoarthropathy) is a rare autosomal dominant disorder.
  • It is characterized by progressive skin thickening, digital clubbing, and periosteal new bone formation.
  • The condition almost exclusively affects males.

Observation:

  • A case of typical pachydermoperiostosis in a 31-year-old male is presented.
  • Clinical features included digital clubbing, skin and soft tissue thickening, hyperhidrosis, seborrhea, gynecomastia, and ophthalmic abnormalities.
  • Radiological findings revealed periosteal hyperostosis in both short and long bones.

Findings:

  • Skin biopsies confirmed hypertrophy of the dermis and skin appendages.
  • No endocrine disturbances were identified in the patient.

  • The observed features align with the primary (idiopathic, hereditary) form of pachydermoperiostosis.

    • Implications:

    • Distinguishing primary pachydermoperiostosis from secondary forms associated with lung tumors is crucial for accurate diagnosis and management.
    • This case highlights the characteristic clinical and radiological manifestations of the hereditary disorder.
    • Further research into the genetic underpinnings and potential therapeutic targets for pachydermoperiostosis is warranted.
