A Rare Case of White Colored Gall Stone in Carcinoma Gall Bladder

Aim: To highlight a newer and different type presentation of gall bladder stone.

Presentation of Case: 40 years old lady operated for cholelithiasis. Post-surgery when the gall bladder lumen was cut open it revealed a solitary, crystalline, white colored stone with irregular surface. The gall bladder mucosa also had a growth at the fundus which was later reported to be papillary adenocarcinoma of gall bladder in histopathology.

Discussion: Broadly gall stones are classified on the basis of their composition. They may be Cholesterol stones, mixed stones or Pigment stones. Majority of the times the type of stone can be identified by their color. Cholesterol stone can vary from whitish yellow to green to black in color. They are hard, multiple and faceted. Pigment stones again classified into black and brown in color. They are multiple, brittle and may be speculated. In our case the stone was totally white in color with speculated surface which is a very rare presentation and was found in a case of carcinoma gall bladder.

Conclusion: Presentation of such white color stones is very rare. Also this is the first case in which this type of stone has been found in association with carcinoma gall bladder.
