O. Mejjad et al., OSTEOARTICULAR MANIFESTATIONS OF PUSTULOSIS PALMARIS-ET-PLANTARIS ANDOF PSORIASIS - 2 DISTINCT ENTITIES, Annals of the Rheumatic Diseases, 55(3), 1996, pp. 177-180
Objective-To test the hypothesis that pustulosis palmaris ct plantaris
and psoriatic arthritis (PsA) are two distinct diseases, and that the
associated dermatoses are therefore also distinct diseases. Methods-W
e prospectively performed clinical, radiological, biological, and bone
scan investigations in 23 outpatients with pustolotic arthritis and 2
3 outpatients with PsA, matched by gender, age (+/- one year) and dura
tion of arthritis (+/- two years). Results-The anterior chest wall, es
pecially the sternocostoclavicular joints, was more frequently involve
d in pustulotic arthritis than in PsA, both clinically (82% v 43%; p <
0.001) and radiologically (47% v 17%; p < 0.05). Sternocostoclavicula
r joints generally presented with erosive lesions in PsA, and with lar
ge ossifications in pustulotic arthritis. Peripheral joint involvement
was mono- or oligoarticular, affecting proximal joints, in pustulotic
arthritis (74% v 21%; p < 0.01), and polyarticular, involving small d
istal joints, in PsA (60% v 0%; p < 10(-4), in which condition it was
also more often erosive (43% v 8%; p < 0.01). The frequency of sacroil
iitis and of spine involvement was similar in pustulotic arthritis and
PsA. Biology and bone scan did not help distinguish between the two g
roups. Conclusions-Pustulotic arthritis and PsA are clinically and rad
iologically different, therefore pustulosis palmaris et plantaris and
psoriasis are most probably distinct dermatological diseases.
