Psoriatic arthritis (PsA) is a chronic, immune-mediated inflammatory arthritis associated with psoriasis, affecting joints, entheses, and the axial skeleton. While primary care providers and dermatologists frequently encounter psoriasis (PsO), early recognition of PsA remains critical to preventing irreversible joint damage. This paper is written to provide a comprehensive overview of PsA, beginning with a clinical case that highlights diagnostic and therapeutic challenges. In this review, the epidemiology of PsA will be discussed, emphasizing its prevalence and risk factors among patients with PsO. The discussion extends to the underlying pathogenesis, focusing on genetic predisposition, environmental triggers, and key cytokines, including TNF-α, IL-17, and IL-23, that have become targets for advanced therapeutics. The clinical features of PsA are explored in detail, including peripheral and axial arthritis, enthesitis, dactylitis, and extra-articular manifestations. Diagnostic approaches are discussed, with a focus on the Classification Criteria for Psoriatic Arthritis (CASPAR) and Moll & Wright criteria. Additionally, we examine screening tools designed to facilitate early detection in dermatology clinics. Diagnostic modalities, including imaging and serologic markers, are reviewed. Finally, we explore the evolving landscape of PsA treatment, spanning conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), biologic agents (bDMARDs), and targeted synthetic DMARDs (tsDMARDs). Given the increasing availability of cytokine-targeted therapies, an interdisciplinary approach between dermatologists and rheumatologists is essential for optimizing outcomes in PsA patients. Patients with PsA are cared for by rheumatologists, dermatologists, and primary care providers who help manage the comorbidities associated with PsA. By bridging primary care, dermatology, and rheumatology in the care of PsA, this paper aims to enhance understanding of PsA for facilitating early identification and timely intervention for improved patient care.

We report a case of an immunocompetent individual who was diagnosed with fungal tenosynovitis of the wrist caused by Cyberlindnera rhodanensis, a yeast in the Saccharomycetales order that has never been reported to cause infections in humans. The yeast grew in routine culture and was sent to a reference laboratory for identification and susceptibility testing. The patient ultimately received six surgeries and five months of antifungal therapy, including micafungin and voriconazole, before clinical resolution.
