[Osteopecilia associated with psoriatic arthritis]

Area of Science:

• Rheumatology
• Radiology
• Genetics

Background:

• Osteopetrosis is a rare benign condensing osteopathy.
• Association with inflammatory rheumatism is exceptionally uncommon.

Observation:

• A 25-year-old patient with psoriasis presented with inflammatory groin pain, limited hip motion, and leg length discrepancy.
• Imaging revealed osteopetrosis with destructive coxitis and bilateral sacroiliitis.

Findings:

• Laboratory tests indicated an inflammatory syndrome with a negative immunological assessment.
• The diagnosis of psoriatic arthritis co-occurring with osteopetrosis was established.

Implications:

• This case highlights the importance of diagnostic radiology in identifying osteopetrosis and associated conditions.
• Timely diagnosis prevents unnecessary investigations and treatments for patients with inflammatory symptoms.
