[A hundred cases of multiple primary neoplasms in association with genitourinary cancer].

There were 970 patients who were diagnosed as having genitourinary cancer at Yamagata Prefectural Central Hospital between 1975 and 1990, and of whom 100 cases (10.3%) had multiple primary malignant neoplasms in addition to their genitourinary cancer. They were compared with 220 patients having single genitourinary cancer and 274 having benign prostatic hypertrophy without past histories of cancer. The genitourinary organs involved with cancers included the prostate (50 patients), urinary bladder (43 patients), ureter or renal pelvis (15 patients) and kidney (7 patients). In the prostate cancer, the incidental carcinomas occupied 30%. The other organs accompanying the genitourinary cancers included the stomach, lung and colon. In patients of multiple primary cancers, single genitourinary cancer and benign prostatic hypertrophy, positive family histories for cancer were observed in 40.0%, 37.7% and 33.2%, respectively, with no significant difference between these groups. Histories of smoking were observed in 54.0%, 38.2% and 34.3% respectively, with significant difference between the multiple primary neoplasm patients and the other 2 groups (p < 0.01). There were two cases in whom the second cancer could be possibly caused by the exposure to radiation for the first cancer. No oncotherapeutic drugs or occupational exposure could be seriously suspected of the cause of the second cancers in the present cases.

[Silicate urolithiasis: a case report].

A 62-year-old male visited our department complaining of left flank pain and urinary retention on November 6, 1989. Intravenous pyelography showed small stone shadows in bilateral ureters and lower calyx of kidney and the left kidney was not visualized. Endoscopically, calculi were seen in bilateral ureteral orifice. An ureteral catheter could not be passed up from there bilaterally. On November 13, 1989, January 24 and 26, 1990, calculi were passed out spontaneously. Analysis of the stones revealed silica calculus. The patient had a past history of duodenal ulcers. He was administered magnesium silicate and magnesium alminometasilicate as an anti-acid drug for ten years. Sixteen cases of silica calculus in Japan are reviewed.

[Ureteral endometriosis: a case report].

A 32-year-old female visited our clinic with the chief complaints of macroscopic hematuria and pollakisuria in February 18, 1987. Cystoscopic examination revealed findings of cystitis but bleeding from the ureteral orifice was not observed. IVP showed right non visualized kidney and retrograde pyelography demonstrated right ureteral stenosis on the lower ureter and right hydronephrosis. Total hysterectomy, right oophorectomy and right ureterolysis were carried out in March 5. Right lower ureter was buried in the fibrous tissue approximately over 2 cm above the crossing with iliac vessels. Dark reddish colored small tumor was noticed in the stenosed ureter and resected. The histological diagnosis confirmed endometriosis. A total of 37 cases of ureteral endometriosis in the Japanese literature was reviewed.

[Prostatic cancer with cystic degeneration: a case report].

A 73-year-old man with prostatic cancer with cystic degeneration is reported. He visited our clinic for postoperative examination of left metastatic lung cancer and treatment of prostatic hypertrophy. When the prostatic biopsy was performed, bloody fluid was aspirated and prostate size on digital examination was reduced. The obtained specimen consisted of scar tissue. Urethrography showed an elongation of prostatic urethra in addition to the compression of urinary bladder from the rear. CT scan demonstrated a prostatic cyst approximately 8 cm in diameter with an irregular margin. Following the transurethral resection of the prostate, the prostatic cyst was opened and papillary tumor observed. Histological examination revealed a well differentiated medullary cancer which coincided with the pathological finding of left metastatic lung cancer. He died from dyspnea caused by pleuritis carcinomatosa 6 years later. Nine cases of prostatic cancer with cystic degeneration in the Japanese literature are reviewed.

[Localized amyloidosis of the ureter: a case report].

A 58-year-old woman was introduced to our department complaining of lower abdominal pain and macrohematuria in March, 1978. Intravenous pyelography revealed stenosis and a ureteral stone on the right distal ureter. In May, 1983, she visited our department again. Endoscopically, bleeding from the right ureteral orifice was observed. Retrograde pyelography demonstrated the right hydronephrosis and irregular margin of the right lower ureter. However, the urine cytology was negative, and CT scan and ureteroscopy showed no tumorous lesion on the portion. On 7 August, 1989, partial ureterectomy and end to end anastomosis was performed. Histopathological examination by H-E and Congo red stain proved amyloid deposition. Postoperative course was uneventful. A total of 40 cases of amyloidosis of the ureter in the world are reviewed.

[A case report of Cushing's syndrome due to adrenocortical nodular dysplasia, with remission period of 6 years after unilateral adrenalectomy].

A 29 y.o. female had been associated with Cushing's syndrome, gradually, from 1977. She was advised to get further examination at our hospital on September 1980. A pre-operative diagnosis of Cushing's syndrome due to bilateral adrenocortical tumors was made and right adrenalectomy was performed on December 22, 1980, as the 1st of two stage operation. The right adrenal, 1.8 cm in diameter, had a pigmented nodule and multiple pigmented micronodules, which were diagnosed pathologically as primary adrenocortical nodular dysplasia. It was not necessary for this patient to maintain steroid therapy, but after 3 months she complained of the withdrawal syndrome and was administered dexamethasone. Since July, 1981, she had no symptom without adrenocortical steroid administration. In November 1986, she became cushingoid and on June 1, 1987, we performed left adrenalectomy on her. The appearance of the left adrenal was similar to the right. We have found no reports of the cases of adrenocortical nodular dysplasia such as delayed appearance of withdrawal syndrome after unilateral adrenalectomy. In this case, plasma ACTH had relatively poor correlation with cortisol. Her plasma ACTH was not always suppressed and sometimes within normal range. Her adrenals had not only autonomy but also pituitary dependency. It is concluded that in this case there may have been a pituitary-adrenal dual control.
