Malakoplakia is a rare disease. Clinical presentation is non-specific, making its diagnosis an incidental finding on histopathological analysis. The aim of this case report is to describe a patient diagnosed with colon, renal and soft tissue malacoplakia mimicking a locally advanced colorectal cancer. A 75-year-old man was admitted due to intense abdominal pain. No relevant findings at the physical examination. Computed tomography showed parietal thickening of the descending colon with left kidney, iliopsoas muscle and retroperitoneum involvement. An elevated blood serum creatinine, elevated glycated hemoglobin and urinary infection were detected. Surgery was decided for suspicious symptomatic colonic neoplasm. Left segmental colectomy with left partial nephrectomy and retroperitoneal soft tissue resection was performed. Pathology report was compatible with malakoplakia. Malakoplakia is a rare disease and may affect multiple organs. Because there are no clinical-specific findings, diagnosis is usually made with histopathological study of the surgical specimen.
