Abstract

Malakoplakia is an unusual characteristic inflammatory condition, it is distinctive feature is the presence of histiocytic cells with eosinophilic granular cytoplasm, often known as “von Hansemann’s histiocytes”, along with the pathognomonic siderocalcific Michaelis-Gutmann bodies (MGBs). We present a case of malakoplakia within a colonic adenoma seen against a background of Enterococcus infection. To our knowledge, this is a unique presentation which has not previous been described.
