## Abstract

An inflammatory condition known as adult-onset Still's disease (AOSD) is typified by quotidian (daily) fevers, arthritis, and a transient rash. This report details the case of a 21-year-old female patient who presented to our hospital with polyarthritis, a red rash, and a high-grade fever for more than three months. History was suggestive of AOSD, which was further proved by investigation and Yamaguchi criteria for AOSD. Steroids and methotrexate were started, to which the patient responded very well and thereafter.
