Eosinophilic cystitis complicated with cystitis glandularis: a case report

Abstract

Abstract Background Eosinophilic cystitis (EC) is a rare inflammatory disease characterized by the gathering and infiltration of numerous eosinophilia (EOS) in the bladder wall. Because of Few cases of EC have been reported globally, the epidemiology of EC is not well known. We report herein the details of one very scarce case of large tumor-like eosinophilic cystitis complicated with cystitis glandularis (CG) diagnosed by biopsy. Case presentation A 45-year-old Chinese man was referred to our hospital for the treatment of right lumbago and odynuria. Ultrasound examination indicated the low echo on the right portion wall and the neck of the bladder. Computed tomography showed a remarkable enhancing large mass that measured 5.0 cm × 2.3 cm located on the right portion of the bladder with undefined margin. For further treatment, diagnostic transurethral resection of the bladder was performed, the postoperative histopathological diagnosis was EC complicated with CG. After transurethral resection, antibiotics, glucocorticoids, and antihistamines were treated. The patient recovered uneventfully and was discharged on postoperative day 8 without evidence of recurrence followed-up for 6 months. Conclusion Large tumor-like eosinophilic cystitis complicated with cystitis glandularis is rare, malignant tumors need to be ruled out. We deem that prompt biopsy led to the exact diagnosis, appropriate treatment led to better prognosis.
