Recurrent bladder malakoplakia: A rare bladder lesion mimicking malignancy.

Background: Malakoplakia is a rare granulomatous disease that commonly involves the genitourinary tract with the urinary bladder being the most frequently affected site. It is characterized by histiocytes containing distinct basophilic calcified inclusions called Michaelis-Gutmann bodies. It is believed to result from abnormally functioning macrophages, with inclusions representing calcifications around incompletely digested bacteria.

Pulmonary malakoplakia due to Prescottella (Rhodococcus) soli in a renal transplant recipient: First reported case.

Prescottella (Rhodococcus) soli is a soil-dwelling organism not previously thought to be pathogenic in humans. We discuss the case of a 78-year-old male renal transplant recipient presenting with respiratory symptoms and multiple pulmonary nodules, found to be pulmonary malakoplakia secondary to infection with Prescottella (Rhodococcus) soli. Treatment was commenced with vancomycin, meropenem and azithromycin for an induction period of two weeks and continued with indefinite oral moxifloxacin and azithromycin with significant clinical improvement.

A rare case of prostatic malakoplakia with multidrug-resistant Escherichia coli: a case report.

Prostatic malakoplakia is an uncommon chronic inflammatory disorder, tumor-like but non-cancerous, the diagnosis of which pivots crucially on the identification of characteristic Michaelis-Gutmann bodies within the pathological tissue. We hereby present an inaugural case report of prostatic malakoplakia concurrent with sepsis caused by multidrug-resistant Escherichia coli, verified through blood culture and metagenomic next-generation sequencing (mNGS). The pathogenesis might be associated with infections by Escherichia coli, immune system irregularities, or lysosomal dysfunction.

Retroperitoneal Malakoplakia Mimicking Metastatic Disease.

Malakoplakia is a rare inflammatory granulomatous disease that can produce a tumor-like appearance in nearly any organ system. Imaging findings of malakoplakia overlap with malignancy and tissue sampling are typically required for definitive diagnosis. We present a case of a 66-year-old woman with a previous history of liver adenocarcinoma status post resection that subsequently developed an intensely FDG-avid retroperitoneal mass on surveillance imaging.

A Case Report of Malakoplakia of the Gallbladder: A Diagnostic Challenge and Pathological Surprise.

Malakoplakia, a rare granulomatous inflammatory condition, typically manifests in the genitourinary system. Its occurrence in the gallbladder is exceptionally uncommon, posing significant diagnostic challenges. A 68-year-old male presented with recurrent epigastric pain, and a suspicious gallbladder mass was found on imaging.

A very complicated UTI: malakoplakia following E. coli urinary tract infection.

Malakoplakia is a rare inflammatory disorder believed to result from a defect in macrophage phagocytic function triggering a granulomatous reaction. It can present with genitourinary, gastrointestinal, or cutaneous manifestations in immunocompromised or, less commonly, immunocompetent hosts. We describe a case of renal malakoplakia in a young, otherwise healthy patient presenting with nephromegaly and sepsis following an E.
