This kidney biopsy shows the histologic features characteristic of malakoplakia, which includes a dense, often obliterative, inflammatory infiltrate rich in histiocytes (Fig. 1 and 2) with numerous small intracytoplasmic concretions known as Michaelis-Gutmann bodies (these are best identified using histochemical staining for calcium as in Fig. 3). Malakoplakia is thought to result from chronic bacterial infection of the urinary tract (the most common causative organism is E. coli). Many cases are associated with the formation of small plaques and/or mass lesions. The bladder is the most common site of involvement, but kidney involvement occurs in about 15% of cases. The differential diagnosis includes xanthogranulomatous pyelonephritis.

Case of Microglandular Adenosis (MGA) 🔬

An infiltrative low-grade epithelial proliferation with central eosinophilic material, devoid of myoepithelial cell layer, MGA can mimic invasive carcinoma—however, negative ER should raise suspicion🕵️‍♂️.
