“…Our case represents the first example of malacoplakia of the gallbladder associated with the presence of microorganisms, since cultures of gallbladder bile or staining for microorganisms have been negative in two of the previous reported cases 4,5 and not assessed in the latter 6 . It is possible that in those rare conditions in which bile is no longer sterile, microorganisms may represent the trigger for the Liesengang phenomenon.…”

“…The latter (represented only by case 17 in their series) was characterized by the presence of Michaelis‐Gutmann bodies in an otherwise typical xanthogranulomatous cholecystitis. Since then, two additional cases of malacoplakia involving the gallbladder have been reported in English literature 5,6 . That described by Charpentier et al 5 .…”

Malakoplakia of Gall bladder is a rare pathological entity with only a handful of cases reported in the literature. Clinically it can mimic carcinoma gall bladder or chronic cholecystitis. It can give rise diagnostic dilemma and influence intraoperative and postoperative decision making. It is almost never possible to make a pre-surgical diagnosis of gall bladder malakoplakia. Hence it remains as a histopathological surprise. Here, we describe two cases of Malakoplakia of gallbladder, both of which were presented as chronic cholecystitis and following pathological analysis of gall bladder specimen was proven to be malakoplakia.

“…Development of malakoplakia in chronic cholecystitis could be in the background of otherwise a typical xanthogranulomatous cholecystitis, which is thought to result due to unsuccessful phagocytosis of the bile material 5 6 10. Another important implicated hypothesis is a defective immune regulatory system resulting in an impairment of mononuclear phagocytosis and lysosomal hydrolytic functions observed in alcohol abuse, malnutrition, postorgan transplant, intake of certain drugs such as steroids or cytotoxic agents, malignancy and chronic diseases such as diabetes mellitus, autoimmune disease and sarcoidosis 2 7.…”
