diagnosis

differential diagnosis and treatment of primary mesenchymal chondrosarcoma of the bladder. Methods Retrospectively reviewing the diagnosis and treatment of a case of primary mesenchymal chondrosarcoma of the bladder

reviewing the relevant literature

and summarizing the clinical features of primary mesenchymal chondrosarcoma of the bladder. Results In this paper

we report a case of a female

69 years old

with recurrent urinary frequency and urgency and painful urination for 3 months as the main clinical manifestation. She had cervical cancer 12 years ago

which was treated with radiation therapy and clinically cured. Ultrasound and radiographs suggested bladder stones

and cystoscopy revealed a stone-like mass attached to the left wall of the bladder. Conclusion Mesenchymal chondrosarcoma of the bladder is an extremely rare malignant tumor of the bladder

the etiology of which is not clear at present. The most common initial symptom for this disease is sarcoid hematuria

but there are also cases with urinary tract irritation

difficulty in urination

and fluid accumulation and obstruction in the upper urinary tract as the initial symptom. The disease is highly malignant and prone to recurrence

early metastasis and poor prognosis; it should be treated with radical cystectomy once diagnosed.
