A rare case of bladder chondroma

Abstract

Soft tissue chondromas are benign tumours that arise commonly in the hands and feet of adults, but rarely in other locations. Only two prior cases of chondroma of the urinary bladder wall have been reported. We describe a third case and discuss similarities and differences between the three cases reported to date.

Rare case of bladder chondroma causing lower urinary tract symptoms

“…A single reported case of soft tissue chondroma of the bladder was identified in a patient with a recent diagnosis of high-grade urothelial carcinoma of the bladder 3. Due to its rarity, there remains limited evidence to suggest an association between soft tissue chondroma and malignant differentiation 4Table 1 summarises all currently reported cases of bladder chondroma.…”

“…Soft tissue chondromas identified in all locations are usually diagnosed in the fourth to seventh decades of life and have been noted to occur in both men and women with equal frequency 8. Soft tissue chondromas have been reported in pelvic organs including the prostate, scrotum and testis; however, there have only been five reported cases of soft tissue chondroma of the bladder 2–6 8…”

“…All published cases of soft tissue chondroma of the urinary bladder have occurred in women in their fifth to seventh decades with the lesion identified at the anterior wall of the bladder in four cases and at the ventral dome of the bladder in one case 2–6. All cases of soft tissue chondroma of the bladder have been diagnosed during the investigation for abdominal or pelvic pain or lower urinary tract symptoms 2–6. A single reported case of soft tissue chondroma of the bladder was identified in a patient with a recent diagnosis of high-grade urothelial carcinoma of the bladder 3.…”

“…An extraosseous or soft tissue chondroma is a rare, benign cartilaginous tumour characterised by the formation of mature hyaline cartilage with the majority located within the medullary cavity of long bones 1. Soft tissue chondromas are extremely rare with only five cases affecting the bladder being reported in the literature 2–6. 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.…”
