ABSTRACT: A 58-year-old man presented with lasting nasal obstruction. He had undergone right nephrectomy for renal cell carcinoma 11 years ago and right lobectomy for pulmonary metastasis 10 years ago. Paranasal sinus CT scans showed a soft tissue mass in the bilateral maxillary sinus. Abdominal CT showed left renal mass. Each mass was enhanced on the contrast-enhanced viewing. The paranasal mass biopsy was performed and resulted in profuse bleeding. Pathological examination was a metastasic renal cell carcinoma. After embolization of feeding artery, debulking surgery was performed. Postoperatively he was given radiotherapy and interferon therapy.

ABSTRACT: A 72-year-old female presented with the complaint of left lower abdominal swelling in May, 2005. Laboratory analysis revealed elevated white blood cell counts and C-reactive protein. Abdominal computed tomography showed left ureteral calculi, left hydronephrosis and a mass extending through the perinephric space, psoas major muscle into the left flank and lower abdomen. Echo-guided needle mass biopsy was performed. Histopathological findings revealed xanthogranulomatous changes. Under the diagnosis of diffuse xanthogranulomatous pyelonephritis extended into psoas muscle and subcutaneous tissue, antibiotic therapy was given for 5 months. After reduction of subcutaneous mass, left nephroureterectomy was performed. Histopathological findings revealed xanthogranulomatous pyelonephritis and ureteritis. Postoperative course was uneventful without any relapse of inflammation.

ABSTRACT: We present a case of hemorrhagic adrenocortical adenoma with myelolipoma. A 66-year-old woman was admitted to our hospital for left retroperitoneal mass. Based on abdominal computed tomography, magnetic resonance imaging and blood tests, preoperative diagnosis was a sarcoma of renal capsule origin. En bloc resection of adrenal gland, tumor, and the kidney with lymph node dissection was performed. Histologically, the mass was diagnosed as hemorrhagic adrenocortical adenoma with myelolipomatous foci.

ABSTRACT: A 73-year-old man with primary small-cell carcinoma of the bladder was treated by radical cystectomy with neoadjuvant chemotherapy. Pathological complete remission was achieved by combination chemotherapy composed of cisplatin, etoposide and irinotecan. The patient is free of disease 19 months after surgery.

ABSTRACT: We report a case of myxoid liposarcoma developed in the right inguinal region. A 45-year-old man visited our hospital with a chief complaint of painless right inguinal mass. He was diagnosed with right direct inguinal hernia for the first time and received a hernia repair. However, the size of the inguinal mass increased gradually after the operation. Then, the tumor was re-evaluated by imaging study such as ultrasonography, computed tomography and magnetic resonance imaging. A fatty mass 4.0 cm in diameter was demonstrated and the tumor was diagnosed as a liposarcoma preoperatively. In addition to the right high orchiectomy, surrounding fatty tissue was also removed at the time of the operation. Histological examination revealed a myxoid liposarcoma and the existence of several daughter regions outside the pseudo-capsule. Right spermatic cord and testis were intact. Postoperatively, he received 54 Gy dose of radiation therapy to right inguinal region for the prevention of the local recurrence of the disease.

ABSTRACT: A 30-year-old man was referred to our hospital with a complaint of male infertility, presenting abnormal semen analysis (semen volume 0.1 ml, sperm concentration 1.2 x 10(6)/ml, sperm motility 0%). Radiological examinations demonstrated right renal agenesis and a cystic mass extending from the prostate to the posterior of the bladder. Our final diagnosis was obstruction of the ejaculatory duct secondary to right ectopic ureter associated with ipsilateral renal agenesis. The patient was treated by transurethral unroofing of the cyst. Three months after the surgery, the cystic mass disappeared and the seminal findings showed marked improvement.
