“…Escherichia (E.) coli is commonly isolated in CM [3]. Histopathology is required for definitive diagnosis and typically shows sheets or aggregates of histiocytes (von Hansemann cells) with abundant eosinophilic cytoplasm containing pathognomonic, laminated Michaelis-Gutmann bodies, which are caused by calcium deposits on residual bacterial glycolipids in the phagolysosomes after inadequate phagocytosis of bacteria [5,6].…”

“…Primary CM is very rare; about 55 cases have been reported to date [9][10][11]. Cutaneous malakoplakia lesions were mainly distributed on the perineum (41 %) [6], abdominal wall/thorax, head and neck, extremities and axilla. Possible theories for the extragenital distribution of lesions include inoculation from the perineum, association with drainage sites [12] or surgical scars and skin folds that harbor microorganism [5].…”

“…Bei einer CM wird häufig Escherichia (E.) coli isoliert [3]. Die Histopathologie ist für die endgültige Diagnose erforderlich und zeigt typischerweise Blätter oder Aggregate von Histiozyten (von Hansemann-Zellen) mit reichlich eosinophilem Zytoplasma, die pathognomonische, laminierte Michaelis-Gutmann-Körperchen enthalten, die durch Kalziumablagerungen auf restlichen bakteriellen Glykolipiden in den Phagolysosomen nach einer unzureichenden Phagozytose von Bakterien verursacht werden [5,6].…”

“…Eine primäre CM ist sehr selten; bisher wurden etwa 55 Fälle gemeldet [9][10][11]. Kutane Malakoplakie-Läsionen traten hauptsächlich am Perineum (41 %) [6], an der Bauchdecke, am Thorax, an Kopf und Hals, an den Extremitäten sowie in der Axilla auf.…”

“…Se presume que el desarrollo de malacoplaquia está asociado con el mal funcionamiento de los macrófagos, específicamente con alteraciones en las funciones fagocíticas o degradativas de los histiocitos en respuesta a bacterias como Escherichia coli, Klebsiella, Proteus, Mycobacterium tuberculosis, Mycobacterium avium, Staphylococcus aureus, Shigella, Rhodococcus equi y Enterococcus spp. 4 , que dan como resultado un estado inflamatorio crónico. Las lesiones se caracterizan por la presencia de grandes macrófagos e histiocitos espumosos (conocidos como células de Von Hansemann) que contienen los cuerpos de Michaelis-Gutmann.…”
