[Abstract]:Objective to analyze the diagnosis and treatment of malignant mesenchymal chondrosarcoma of prostate. Methods A case of malignant mesenchymal chondrosarcoma of the prostate was retrospectively analyzed. The clinical manifestations, imaging findings, pathological features, treatment and prognosis were analyzed. Results the patient was 59 years old. Because of frequent urination, progressive urination is difficult to diagnose prostatic hyperplasia in external hospital. Transurethral resection of the prostate (TURP) is performed. Postoperative pathology shows malignant mesenchymal neoplasms of the prostate. B ultrasonic examination shows medium echogenic mass in the bladder without obvious movement. The prostate was indistinct and the cystic mixed structure could be seen in the right pelvic cavity. Systemic bone scan showed no clear signs of bone metastasis. MRI examination of the prostate showed that there were multiple nodules and mass soft tissue signals in the pelvic area near the pelvic floor, while the larger ones were located on the right side of the bladder. The patients underwent radical cystectomy and pelvic lymph node dissection under general anesthesia. The pathological examination showed the undifferentiated primitive mesenchymal cells, which were scattered in the islet shaped and highly differentiated chondrocytes. Chondrocytes have mild heterogeneity. Immunohistochemical staining: vimentin and chondrocyte nucleus S-100 positive, undifferentiated cell region S-100, smooth muscle actin, CD34, cell keratin CK7,CK8 were negative. The pathological diagnosis was malignant mesenchymal chondrosarcoma of prostate. The patient refused chemotherapy and other further treatment and died 3 months after the operation. Conclusion the main clinical manifestations of malignant mesenchymal chondrosarcoma of prostate are frequent urination and progressive dysuria. It is necessary to make a comprehensive diagnosis according to the clinical manifestation, imaging examination, histopathology and immunohistochemical examination of prostatic malignant mesenchymal chondrosarcoma. Radical resection is the first choice, and radiotherapy or chemotherapy should be given after operation.
