AI Article Synopsis
- The study aimed to describe the cytomorphology of granulomatous mastitis (GM) and identify its causative agents using microbiologic culture and PCR results.
- A retrospective review of inflammatory breast aspirates from two hospitals in Saudi Arabia revealed 15 cases of GM out of 49 identified cases, with Brucella melitensis and tuberculosis as notable pathogens.
- Fine needle aspiration cytology proved beneficial for early GM diagnosis and classification, emphasizing the importance of combined cytomorphologic features and microbiologic studies for definitive diagnosis.
Article Abstract
Objective: To describe the cytomorphology of granulomatous mastitis (GM) and to evaluate the causative agents involved, proven on the basis of microbiologic culture results and polymerase chain reaction (PCR) studies.
Study Design: We retrospectively reviewed the inflammatory breast aspirates reported at King Abdul Aziz Specialist Hospital and Al Hada Armed Forces Hospital, Taif, Kingdom of Saudi Arabia, from January 2000 until March 2008. The pathology reports, clinical information, slides, microbiologic culture results and tuberculosis (TB)/PCR were reviewed. Cases of inflammatory carcinoma or duct ectasia were excluded.
Results: A total of 49 cases of inflammatory breast aspirates were identified, of which 15 cases were GM. The microbiologic cultures of all 15 cases were available. Six of 15 cases had positive culture for Brucella melitenses, and 2 cases were positive for TB, which was further confirmed by TB/PCR. The fungal cultures were negative in all the cases. Seven of 15 cases were classified as idiopathic GM.
Conclusion: Fine needle aspiration cytology was found to be a useful tool in the early diagnosis of GM and its classification if performed by a pathologist as the material can be submitted for culture. The definitive diagnosis can be established by a combination of the cytomorphologic features and microbiologic studies.

A 75-year-old female presented with fasting hypoglycemic episodes. A supervised fast ended at 72 hours fulfilling Whipple triad, with suppressed insulin and C-peptide levels, but discordantly suppressed serum β-hydroxybutyrate levels. After 21 months of recurring symptoms, a repeat fast ended at 48 hours with Whipple triad, suppressed serum β-hydroxybutyrate level, and borderline nonsuppressed C-peptide level, suggesting endogenous hyperinsulinism.

Objectives: Previous research has conducted meta-analyses on the diagnostic accuracy of endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB). However, studies on adverse events (AEs) have been limited and sporadic and have included a highly diverse group of patients (with upper and lower gastrointestinal tract issues) and needles of varying sizes (19-22-25G). The purpose of this systematic review and meta-analysis was to determine the incidence of AEs related to the utilization of 20-22G second-generation EUS-FNB needles subsequent to puncture of the upper gastrointestinal tract and adjacent organs.

Objectives: Endoscopic ultrasound-guided fine-needle aspiration/biopsy (EUS-FNA/B) is the gold standard for diagnosing gastric subepithelial lesions (SELs), but diagnosing lesions smaller than 20 mm remains challenging. We developed traction-assisted EUS-FNB (TA-EUS-FNB) using the clip-with-thread method to enhance diagnostic accuracy by stabilizing the lesion and providing counter-traction for easier needle access. This study evaluates the effectiveness of TA-EUS-FNB in diagnosing small gastric SELs.

We report the case of a 24-year-old man from Brazil presenting with jaundice and epigastric pain. Abdominal CT and endoscopic ultrasound (EUS) revealed a mass in the pancreatic-duodenal groove, intrahepatic duct dilation, and lymphadenopathy, initially suggestive of lymphoproliferative syndrome. However, cytopathological analysis of EUS-guided fine needle aspiration (EUS-FNA) of the lymph nodes confirmed paracoccidioidomycosis.
