Introduction Retropubic parasymphyseal cysta are rare, and few cases have been reported in men. Case presentation A 65‐year‐old male patient presented with a 6‐month history of pelvic and perineal pain. Magnetic resonance imaging revealed a high‐intensity, irregular‐shaped mass extending from the pubic symphysis to the bladder. Contrast enhancement revealed no uptake in the central part of the mass, indicating a cystic component. Computed tomography showed erosion of the pubic symphysis and pubic osteophytes. Pathological findings of biopsy specimens revealed inflammatory fibrous tissue but no malignancy. The definitive diagnosis was retropubic parasymphyseal cyst associated with inflammation. The patient was treated with cefazolin from 1 day before surgery until postsurgical day 7. Oral antibiotic therapy was then prescribed for 1 month to maximize treatment. After 2 months, the patient’s symptoms resolved. Conclusion Retropubic parasymphyseal cysts with inflammation and smaller asymptomatic cysts can be managed effectively with conservative or minimally invasive treatment.

We report 4 patients, 1 female and 3 males aged 26-74 years, who underwent surgical treatment for renal malignant tumors with supradiaphragmatic extension into the vena cava. All of their tumor thrombi extended to the right atrium as confirmed by magnetic resonance imaging. The distinctive symptom was liver dysfunction caused by disturbance of the hepatic vein drainage in two patients. However, there was no common symptom in these 4 patients. Preoperative metastasis was found only in the female, whose metastasis was solitary in the lung and seemed to be able to be removed easily after radical nephrectomy. All of these 4 patients had radical nephrectomy and removal of the tumor thrombi with the use of cardiopulmonary bypass and temporary exsanguination. In 3 of these patients, the liver was mobilized to expose the retrohepatic vena cava by incision of the falciform, triangular and coronary ligaments. Two patients with vena caval wall invasion had vena cavectomy and an artificial vascular graft was then sutured to replace the caval wall in one of them. Preoperative liver dysfunction was gradually improved after operation and completely recovered about 1 week later. A postoperative complication, wound infection, occurred in only one patient. Pathological examination revealed renal cell carcinoma in 3 patients and nephroblastoma in the remaining one. In renal cell carcinoma, both patients without distant metastasis were alive about 15 months postoperatively. However, the one with lung metastasis died with newly appeared multiple metastases 9 months postoperatively.(ABSTRACT TRUNCATED AT 250 WORDS)
