Isolated cystic duct lymph node tuberculosis.

Tuberculosis of the cystic duct lymph node without involvement of gall bladder is exceedingly rare. Cholelithiasis is a usual accompaniment. A case of 65-year-old woman was diagnosed to have cholelithiasis. Laparoscopic cholecystectomy was performed and a prominent cystic lymph node was excised for biopsy. Histopathology surprisingly reported tuberculosis of cystic duct lymph node without affecting the gall bladder. Thereupon, she was treated with antituberculous chemotherapy.
