[The manifestation of psoriasis arthropathica in later life].

The article deals with a group of 12 patients (8 females and 4 males), who generally first developed arthralgia as a feature of psoriasis beyond the age of 60. In all cases psoriasis arthropatica was diagnosed on the basis of physical, laboratory and X-ray examinations. Radiomorphological changes in the skeletal system are described in detail. The article also contains information on the treatment given, which in later life should be chiefly symptomatic on account of the increased risk of side-effects.
