ABSTRACT
Kikuchi-Fujimoto disease (KFD) is a rare self-limiting necrotizing lymphadenitis found mainly in young women. Patients typically present with lymphadenopathy and often with a high temperature. The etiology of the disease remains unknown, but various viral infection and autoimmune processes have been postulated to be the cause. One theory proposes that KFD may be a self-limiting form of systemic lupus erythematosus (SLE). This theory is strongly supported by the fact that microscopic features of KFD can be very similar to those found in lupus lymphadenitis. The diagnosis of KFD can precede, postdate or coincide with the diagnosis of SLE. No treatment is usually needed and relapse, although possible, is uncommon. Our case describes a young woman, originally diagnosed as having SLE, who subsequently developed recurrent KFD with axillary lymphadenopathy and fever.

An "overlap syndrome" is used to describe patients who have two or more well-defined connective tissue diseases such as rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), systemic sclerosis (SSc), and polymyositis. Their coexistence is defined clinically and often by specific serologic tests. We report a case of dermatomyositis associated with IgA nephropathy that had overlapping features of Sjogren's syndrome. This dermatomyositis and Sjogren's overlap is a rarely reported overlap syndrome worldwide.

BACKGROUND/AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) is the gold standard for diagnosis and treatment of common bile duct stones (CBDS). However it is associated with some complications. Endoscopic ultrasonography (EUS) is an efficient diagnostic tool for CBDS with better accuracy than ultrasonography (USG) or computed tomography (CT) and lower complication rate than ERCP. We evaluated the diagnostic usefulness of EUS in suspicious CBDS. METHODS: From Oct. 2001 to Mar. 2004, 84 patients with the suspicion of CBDS, without definite evidence on CT and/or USG were evaluated with EUS. The reports were reviewed retrospectively. RESULTS: Patients were 38 males, 46 females with mean age of 56 years old. CBDS were found in 25 (29.8%) patients. In the diagnosis of CBDS undetected in CT and/or USG, EUS gave 96% sensitivity, 96.6% specificity, 92.3% positive predictive value and 98.3% negative predictive value. When CBDS were found in EUS, the average sizes of CBD and CBDS were 8.8 mm (4~16.7) and 6.4 mm (3.3~9.1) respectively. Diagnostic ERCP was avoided in 54 (64.3%). EUS provided additional diagnosis such as gallbladder stones, gallbladder cancer, ampullary cancer and adenoma. No complication was associated with EUS. CONCLUSIONS: EUS is reasonably safe and accurate procedure in detecting CBDS. EUS may possibly replace diagnostic ERCP in CBDS.
