Rare case of bladder chondroma causing lower urinary tract symptoms

Abstract

An extraosseous or soft tissue chondroma is a rare, benign cartilaginous tumour characterised by the formation of mature hyaline cartilage. The majority of osseous chondromas are located within the medullary cavity of long bones. Soft tissue chondromas are extremely rare with only five cases affecting the bladder being reported in the literature. Soft tissue chondroma of the bladder is a rare cause of lower urinary tract symptoms and abdominopelvic pain. All reported cases of soft tissue chondromas of the bladder have occurred in women in their fifth to seventh decades of life. We describe the case of a 65-year-old woman diagnosed with a soft tissue chondroma of her bladder while being investigated for lower urinary tract symptoms.

Chondroma of the urinary bladder

“…Cystoscopic examination revealed a whitish submucosal mass with a smooth, well-defined surface. Interestingly, all bladder chondromas reported to date were located at the anterior wall or bladder dome [2][3][4][5][6][7] (Table 1). Transurethral resection is an effective management strategy for bladder chondromas, and no recurrence has been reported following this procedure.…”

“…[1] Extraskeletal soft tissue chondromas are extremely rare, and only 6 cases of bladder chondroma have been reported previously. [2][3][4][5][6][7] Bladder chondromas may cause urinary symptoms, abdominal pain, or hematuria. We report the case of a 75year-old woman in whom bladder chondroma was discovered incidentally and managed by transurethral resection.…”
