Abstract

Systemic Juvenile Idiopathic Arthritis (sJIA) is an infrequent auto-inflammatory disorder observed in pediatric patients, with clinical manifestations typically involve fever and arthritis, often accompanied by additional symptoms such as rash, generalized lymphadenopathy, hepatomegaly and/or splenomegaly, and serositis. Nevertheless, the initial presentation of sJIA frequently lacks specificity and may overlap other pathological entities. The 2001 criteria established by the International Society of Rheumatology, while widely employed, exhibit notable limitations particularly concerning atypical presentations, leading to the utilization of the Yamaguchi criteria to enhance the early detection of sJIA. We present a case involving a 14-year-old patient presenting persistent fever and distinctive cutaneous manifestations. Following the exclusion of alternative etiologies for fever, the patient fulfills the diagnostic criteria for systemic juvenile idiopathic arthritis according to the Yamaguchi criteria. In conclusion, this case highlights the effectiveness of Yamaguchi criteria in diagnosing sJIA, particularly in its early stages. This aids in prompt therapeutic interventions and mitigates potentially life-threatening complications.
