Introduction

Xanthogranulomatous changes have been reported at multiple sites in the urinary system (1), with the kidney being the most common organ. Histologically, there are multinucleated giant cells, lipid-laden macrophages, and cholesterol clefts. Although, xanthogranulomatous cystitis (XC) is an uncommon, chronic, benign inflammatory disease of unknown etiology and was first defined in 1932 (2). It is usually diagnosed as a papillary lesion in the bladder, but lateral wall enrolment is very rare. In this case report, we want to present a patient who had XC because of the pathology of the transurethral resection performed for the papillary lesion on the lateral and posterior bladder wall.

Case Report

A 77-year-old male hospitalized with urgency, frequency, dysuria, hematuria symptoms for nine months period. He has been with urethral catheterized for 6 months due to lower urinary tract obstructive symptoms. The patient was immobile because of paraplegia for 3 years. Hematological and biochemical examinations were normal. Urinalysis showed 23 leukocytes and 580 erythrocytes per high power field. Urine culture was sterile. Urinary ultrasonography revealed diffuse bladder wall thickness (13 mm) and echogenic foci in the posterior wall. Abdomen computed tomography revealed diffuse of the bladder wall thickening, papillary lesions on the right lateral and posterior wall of the bladder and a giant fecaloma in the rectum (Figure 1).

During the cystoscopy, multiple polypoid formations with a cotton-like appearance were observed on the bladder posterior and right lateral wall (Figure 2) .Complete endoscopic resection was performed; the postoperative course was uneventful.

Inpathological assesment xanthogranulatous macrophage cells were positive for periodic acid schiff mark for calcospherules (Michaelis - Guttman bodies). Acid fast bacteriathe mark was negative. CD68 immunohistochemically stained strongly, however, cytokeratin was negative (Figure 3). According to these findings, the patient was diagnosed with XC. That findings did not support malignancy. The patient was given antibiotic prophylaxis for 3 months. At a follow-up after three months there was no recurrence. Patient consent was obtained for this case report.

Discussion

XC is an extremely rare benign chronic inflammatory disease. The first case was published by Wassiljew in 1932 (2). There are 28 XC cases in the literature and most of the cases were urachal remnants and cysts. There are no specific signs of the disease rather than cystitis like symptoms, abdominal pain, occasional hematuria and umbilical discharge. The importance of XC in the bladder is that these symptoms can be confused with bladder cancer. Also, XC in the bladder with papillary lesions can mimic bladder cancer. Accordingly, it is very important to accurately evaluate the pathological results and diagnose the disease.

The XC etiology has not been clarified yet. There are many theories highlighting immunological disorders (3,4), unusual lipid metabolism (5) and urothelial metaplasia resulting from chronic infection (6). Here, the lesions on the right lateral and posterior wall of the bladder showed that they were not caused by the urachus anomaly. As the patient had a urethral catheter for 6 months, chronic irritation of the catheter may have be in this case.

Conclusion

In the XC of the bladder, medical treatment is unsuccessful therefore conservative treatment is uncommon. Although partial resection was performed 22 cases in the literature, the most effective treatment for small lesions is complete endoscopic resection. The etiology of XC is unclear. Although the urine culture was negatif, give antibiotic may be helpful for preventing the disease.
