A case report of adult-onset Still’s disease of a patient presenting with the symptoms of intraparotid lymphadenopathy

Adult-onset Still’s disease (ASOD) is rare in adults. We herein report a 21-year-old female patient with swelling on right cheek, fever, sore throat, and myalgia for two months. The radiologic, pathologic, laboratory and serologic investigations led to no specific diagnosis. Our case fulfilled 3 major (fever, arthralgia, and leukocytosis) and 4 minor (pharyngitis, lymphadenopathy in the neck and parotid gland, abnormal liver function test and negative for Rheumatoid arthritis) criteria for the diagnosis of ASOD according to Yamaguchi et al. This was a rare case presenting with intraparotid lymph nodes and diagnosed with ASOD. After corticosteroid treatment, all symptoms, liver function tests and inflammatory parameters regressed to normal ranges.
