Society for Publication of Acta Dermato-Venereologica Prurigo nodularis (PN) is a chronic pruritic skin disorder with an estimated prevalence of 6–72 per 100,000 individuals worldwide. PN is found in all age groups, with the highest incidence in people aged over 50 years. The clinical picture of PN is characterized by lichenoid or excoriated nodules, typically appearing on the trunk or extensor side of the extremities (1). Recent studies have reported an association between PN and various comorbidities (2, 3) such as hyper tension, lipid disorders and type 2 diabetes (3), as well as autoimmune conditions, such as coeliac disease and type 1 diabetes (3, 4). Similar to other dermatological diseases, PN is often accompanied by psychiatric disorders (3). Very few studies have been conducted on comorbidities of PN in Northern Europe (5). The present study was designed to evaluate the comorbidities associated with PN in Northern Finland.
