ABSTRACT
Psoriasis is a common multisystem inflammatory disease, and arthritis is an essential component of the disorder, requiring early diagnosis and prompt treatment for successful management. In this study, we aimed to investigate the relationship between nail and scalp involvement and other covariates with psoriatic arthritis (PsA). This cross-sectional study, conducted from June 2021 through December 2021, included 763 patients from 11 different centers in Turkey. The severity of involvement was evaluated using psoriasis area severity index (PASI), nail psoriasis severity index (NAPSI), and psoriasis scalp severity index (PSSI) scores. Predictors for PsA were evaluated using univariate and multivariate logistic regression models. PsA (nâ =â 155, 21.5%) was significantly more common in patients having a family history of psoriasis (43.2% vs 30.9%, Pâ =â .004), nail involvement (68.4% vs 52.3%, Pâ <â .001), and coexistence of nail and scalp involvement (53.7% vs 39.6%, Pâ =â .002). Furthermore, patients with PsA had considerably higher PASI (7 vs 5.6, Pâ =â .006), NAPSI (5 vs 2, Pâ <â .001), and PSSI scores (7 vs 4, Pâ =â .002) and longer disease duration (months) (126 vs 108, Pâ =â .009). In multivariate analysis, female gender [OR: 3.01, 95% CI (1.861-4.880), Pâ <â .001], nail involvement [OR: 2.06, 95% CI (1.293-3.302), Pâ =â .002)], and body mass index (BMI) [OR: 1.06, 95% CI (1.017-1.100), Pâ =â .005] were identified as independent predictors for PsA. Female gender, nail involvement, and high BMI are significant predictors for PsA and warrant detailed rheumatological assessment. Notably, being female is the strongest predictor of increased risk of PsA in our survey. Scalp involvement appears not to be associated with PsA. Also, the presence of PsA seems related to a more severe skin involvement phenotype.

ABSTRACT CONTEXT: Localized scleroderma (morphea) is characterized by fibrosis of skin and subcutaneous tissue. Granuloma annulare is a relatively common disease that is characterized by dermal papules and arciform plaques. CASE REPORT: Here, we present the case of a 42-year-old woman who developed granuloma annulare on the dorsum of her feet and abdominal region, and morphea on the anterior side of her lower limbs. We also discuss the etiological and pathogenetic processes that may cause the rare coexistence of these two diseases. CONCLUSION: Only a few cases in the literature have described coexistence of morphea and granuloma annulare.
