Summary
Radiography revealed characteristic hand bone lesions in psoriatic patients, even without joint symptoms. These findings suggest psoriasis is a systemic disease with bone manifestations alongside skin issues.
Area of Science:
- Dermatology
- Radiology
- Rheumatology
Background:
- Psoriasis is a chronic inflammatory skin condition.
- Subclinical bone involvement in psoriasis is not well understood.
- Radiographic hand changes may indicate systemic disease activity.
Purpose of the Study:
- To investigate radiographic hand abnormalities in psoriatic patients without clinical arthropathy.
- To identify characteristic radiological markers of psoriasis in the hands.
- To explore the relationship between cutaneous and bone manifestations of psoriasis.
Main Methods:
- A radiographic study using microradioscopy (optical enlargement) was performed.
- 58 patients with various clinical forms of psoriasis were included.
- Patients had no clinical symptoms of arthropathy.
Main Results:
- Significant incidence of focal discontinuity/irregularity of tuft cortical (nail-stroke appearance).
- Focal lamellar periosteal thickening, intraspongous geodes, increased intracortical striae, and juxta-articular erosions were observed.
- A characteristic pattern of monolateral, combined lesions, especially tuft cortical erosions, was identified.
Conclusions:
- The observed radiographic hand lesions are a potential marker for psoriasis.
- Psoriasis may be a systemic disease with accelerated turnover.
- Cutaneous and bone lesions represent different clinical expressions of the same underlying biological process.
