ABSTRACT A less documented entity of psoriatic arthritis was studied in 238 cases of psoriasis and it was detected in 5.1% of cases. The prevalence of arthritis was found in the population over 40 years of age and was 2.7% of the males and 8.2% of the females. Psoriatic arthritis was much more common in females (male to female ratio=1:2) in contrast to male predominance in psoriasis (male to female ratio=1.6:1). Skin lesions usually precede the arthritis (50%); in others the onset is synchronous (41.7%) and in few of them the arthritis may come first (8.3%). Athritis is commonly encountered with moderate to severe involvement of skin (75%). In deforming type of arthritis the psoriasis was extensive and exfoliative (17%). The nails are more frequently involved at the onset of the arthritis. Rose‐Waaler Test was negative in all of them. Anaemia (41.6%) and raised ESR (25%) was a feature in the active phase of the disease. Hyperurecaemia was noted in 41.6% of cases, indicating towards the extensive involvement of skin. The importance of radiological evaluation of spine, sterno‐clavicular and sacro‐iliac joints in all patients is stressed. Certain unusual features noted in the presented series of cases are; calcaneal spur (17%), spondylolisthesis (8.5%) and presence of LE cells (8.3%).
