Abstract
A 77-year-old woman developed epigastric pain. She was diagnosed as having cholecystolithiasis at other clinic and referred to our hospital for surgery. We electively performed a laparoscopic cholecystectomy. An enlarged lymph node was found by the gallbladder neck and was also resected. On pathology, Langhans giant cells, a granuloma consisting of epithelioid cells with caseation necrosis were found in the lymph node, and tuberculous lymphadenitis was diagnosed. On chest and abdominal CT, no abnormalities were found ; tubercle bacillus was not identified in the sputum. A 4-drug antituberculous regimen (isoniazid, rifampicin, ethambutol, and pyrazinamide) was given postoperatively.
