Pelvic malakoplakia simulating recurrence of rectal adenocarcinoma: report of a case.
Malakoplakia represents a chronic inflammatory disease associated with a broad spectrum of bacterial infections. On histopathology, Michaelis-Gutmann bodies are considered as pathognomonic histopathological findings. Rarity of the disease and wide variety of clinical presentation makes its diagnosis very challenging. We report herein the case of a 66-year-old woman who, having undergone lower anterior resection for rectal adenocarcinoma 3 and a half years ago, presented with urinary frequency and dull abdominal pain. CT scan revealed a soft tissue tumour infiltrating the preperitoneal fat over the urinary bladder, which was considered as recurrence of the rectal carcinoma. On laparotomy, a tumour invading the bladder, small intestine and the anterior abdominal wall was resected and the patient recovered uneventfully. On histopathology, malakoplakia of urinary bladder was revealed. Overstaging of patients' malignancy due to malakoplakia is not uncommon, so its early identification can help avoid incorrect treatment.
