Bladder malacoplakia: A case report.

Background: Bladder malacoplakia is a rare chronic granulomatous disease. The most common site of the malacoplakia is the urinary system. The etiology of bladder malacoplakia is complex, with its clinical misdiagnosis rate is high. Therefore, exposure to more clinical cases is necessary to improve the diagnosis and treatment of this condition.

Case Summary: A 65-year-old woman was admitted to our hospital because of dysuria. She presented with dysuria, frequent urination, urgency, pain, and absence of hematuria and pyuria. After the examination, bladder tumor electrocision was performed under combined intravenous and inhalation anesthesia on September 6, 2021. During the operation, electrotomy and electrocoagulation were performed. The operation was then followed by anti-infection treatment, and the patient recovered well. The postoperative pathology was diagnosed as bladder malacoplakia by light and electron microscopic analyses. On a follow-up after 4 mo, no significant difference between electrotomy and electrocoagulation was found, with both achieving a curative effect.

Conclusion: Diagnosing bladder malacoplakia depends on histopathological examination. Antibiotic treatment with bladder tumor resection or electrocoagulation provides better therapeutic effect.
