[Pulmonary tuberculosis manifesting predominantly as ileus secondary to peritoneal tuberculosis in a young man].

A 27-year-old man was admitted to our hospital because of abdominal pain and vomiting. A radiograph of the chest revealed widening of the right superior part of the mediastinum, and an abdominal radiograph showed many air-fluid levels. A computed tomographic scan of the chest revealed a solitary nodule in the right anterior lobe of the lung, and right paratracheal lymphadenopathy.

Polymyositis and Sjögren's syndrome associated with bronchiolitis obliterans organizing pneumonia.

Bronchiolitis obliterans organizing pneumonia (BOOP) occurred in a 53-year-old woman with well-documented Sjögren's syndrome (SjS) and polymyositis (PM). BOOP has often been reported as a pulmonary manifestation of collagen vascular diseases, mainly rheumatoid arthritis (RA), but the association of BOOP and PM has rarely been documented. A search of the literature showed only 16 case reports of BOOP associated with polymyositis-dermatomyositis (PM-DM).

Endopyelotomy in horseshoe kidneys.

Three patients aged 23 to 43 years underwent endopyelotomy to treat stenoses of the ureteropelvic junction (UPJ) in horseshoe kidneys. One patient had failed open primary pyeloplasty and division of the isthmus previously. The other two patients had primary UPJ obstruction and small caliceal calculi associated with horseshoe kidneys.

[Percutaneous resection of renal pelvic carcinoma: a case report].

A 72-year-old male patient underwent antegrade percutaneous resection of a solitary and papillary tumor in the lower calyx of left kidney. He had undergone right nephroureterectomy one month previously due to right nonfunctioning kidney caused by right ureteral carcinoma. Percutaneous electroresection of the tumor was performed after puncture of a lower calyx.

Squamous cell carcinoma of ureter extending into renal vein. Positive immunohistochemical staining for carcinoembryonic antigen.

A case of squamous cell carcinoma of the ureter with extension into the renal vein is presented. Immunoperoxidase method revealed positive staining for carcinoembryonic antigen. The literature on ureteral tumors is reviewed with special reference to renal vein involvement and carcinoembryonic antigen.

[Pure leiomyoma of prostate presenting with rectal symptoms: a case report].

Pure leiomyoma of the prostate is a rare lesion. We report a case in a 68-year-old man who presented with rectal symptoms. Rectal examination showed a stony hard nodule with irregular surface near the apex of the prostate.

[A case of metastatic urinary bladder tumor from gastric carcinoma].

We report a case of metastatic bladder tumor from gastric carcinoma. A 55-year old male patient was referred to our urological clinic with a complaint of frequent urination and voiding pain. He had undergone total gastrectomy for poorly differentiated adenocarcinoma, signet-ring cell type, 9 months earlier.

Primary localized amyloidosis of the renal pelvis coexisting with transitional cell carcinoma: a case report.

Primary localized amyloidosis of renal pelvis is very rare, and only 12 cases have been reported. More than half of the reported cases were treated by nephrectomy, and the preoperative diagnosis could not be made correctly because of its resemblance to renal pelvic tumor. The ureteroscopy is a useful diagnostic means in such a condition.

[Treatment of benign prostatic hypertrophy using balloon dilation].

Balloon dilation of the prostatic urethra was performed for the management of benign prostatic hypertrophy. The patients selected were mainly high risk patients who were poor surgical candidates for transurethral resection of the prostate. Ten patients between 61 and 87 years old with a mean age of 77.

Extraprostatic localization of prostatic acid phosphatase and prostate-specific antigen: distribution in cloacogenic glandular epithelium and sex-dependent expression in human anal gland.

Immunoreactivities of prostatic acid phosphatase (PACP) and prostate-specific antigen (PSA) were demonstrated in normal anal glands of males (11 of 25) and urethral glands of both sexes (six of six), by indirect immunoperoxidase staining. These prostatic antigens were colocalized in nonmucous epithelial cells. In the anal gland, PACP and PSA were distributed exclusively in acinus-forming, tall columnar cells, while columnar cells with brush borders, goblet cells, and transitional cells in the duct were negative.

[Clinical evaluation on differential quantitation of human chorionic gonadotropin in testicular cancer].

In 113 patients with testicular germ cell tumor, the authors determined human chorionic gonadotropin (hCG) and the free beta subunit levels in sera by differential quantitation using homologous hCG-beta radioimmunoassay (RIA) and hCG enzyme immunoassay (EIA), respectively. In 59 patients with seminoma, intact hCG was positive in 6 patients (10.1%), whereas free hCG-beta was positive in 23 patients (39.
