A 63-year-old man complained of hunger epigastralgia. X-ray and endoscopic examination demonstrated Borrmann II type gastric carcinoma. Radical gastrectomy was performed on October 20, 1982. The histological findings revealed moderately differentiated tubular adenocarcinoma. In May 1983, right hydronephrosis was recognized by ultrasonography. A papillary tumor was visualized in the right ureter in retrograde pyelography, and percutaneous transrenal urinary tract drainage was performed. Cytological findings revealed class V. Total nephro-uretectomy was performed on June 16, 1983. The histological findings revealed transitional cell carcinoma.

Two cases of colonic adenocarcinoma appearing 44 and 25 years, respectively, following an operation for urinary bladder exstrophy done according to Maydl are reported. A need for regular controls of patients with inner urine derivations has been emphasized. In the case of a suspected tumour it is necessary to alter the inner derivation to an outer one and also a resection of the colon at the site of the urinary bladder trigone is required. The Czech surgeon Karel Maydl was the first to implant the trigone of a splitted urinary bladder into the colon sigmoideum in 1892. This type of operation is used even today by several European urologists with excellent long-term results with respect to the preservation of an intact ureterovasical passage which prevents the reflux of the intestinal contents into the ureter, and also prevents the formation of strictures in the terminal parts of the ureter. In two patients who had been living for 25 and 44 years since they were operated on for urinary bladder exstrophy according to Maydl, a colonic adenocarcinoma was diagnosed. The tumour directly affected the implanted trigone wall and also involved the surrounding parts of the colon wall.

A case of multicentric papillary adenocarcinoma arising in the renal pelvis and proximal ureteral mucosa of a 35-year-old man is presented. The left nephrectomy specimen demonstrated multiple, fungating, papillary tumors. The largest tumor measured 10 X 9 X 6 cm and invaded the renal parenchyma. Smaller tumors with long stalks were found. Microscopically, the papillary fronds of each neoplasm were lined by a single layer of cuboidal to low columnar epithelium admixed with a few areas of invasive tubular adenocarcinoma. The adjacent pelvic mucosa was the site of cuboidal epithelial metaplasia. The ultrastructure of both the papillary tumor and the pelvic mucosa suggested that they originated from the nonmucigenic metaplastic epithelium with a partial similarity to the lining of the proximal convoluted tubule. The growth pattern and the multicentric development of this unusual neoplasm suggest that this is a case of the malignant counterpart of the nephrogenic adenoma in the kidney and ureter, and reflect a biologic behavior corresponding to ordinary urothelial papillary tumors.

A case of primary adenocarcinoma of the ureter, associated with severe hypocalcemia in a 73-year-old man is reported. The patient had undergone left nephrectomy for pyonephrosis due to a ureteral stone, 29 years previously. On November 4, 1986, he visited the hospital with dysuria and overflow incontinence as the chief complaints. He was admitted with suspicion of prostatic carcinoma, but prostatic stones and chronic prostatitis were proven. However, urine cytology showed adenocarcinoma cells, and a ureteral tumor was found at the right ureterovesical junction. On December 10, right partial ureterectomy, total cystectomy and right ureterocutaneostomy were performed. Moderately differentiated, invasive adenocarcinoma was found at the right ureteral end, 1.5 cm in length and in part poorly differentiated transitional cell carcinoma was present continuously to the adenocarcinoma. Hypocalcemia was cured easily with activated vitamin D3. The patient, 9 months after the operation, is apparently free of the ureteral tumor.

A 50-year-old Japanese male hospitalized with the complaint of fever and pyohematuria. An excretory pyelography revealed the right hydronephroureter due to right ureteral stone. When the ureterolithotomy was carried out, a wide-based and rice-sized tumor co-existed at the site of the epithelium of the ureter lithotomized. Resected tumor was pathologically confirmed as poorly differentiated adenocarcinoma with mitosis. Therefore, total nephroureterectomy with bladder cuff resection was done at 10 days after the first operation. However, malignant cells were not found in the surgical specimen or histologically diagnosed localized glandular ureteritis. He is alive without any evidence of recurrence. It was reported that the glandular metaplasia, a relative rare lesion in the ureter, was correlated with carcinogenesis of adenocarcinoma in urothelium. However, when the lesion is small and localized such as in this case it should be treated with ureterectomy and addition of other suitable adjuvant therapies. Furthermore, endourological techniques which have been recently dramatically progressed may become a weapon against this lesion for both treatment and follow-up.

A 55-year-old man consulted us on December 3, 1986 with the chief complaints of left leg pain, disturbance in gait and dysuria. On digital rectal examination his prostate was found enlarged to a hen's egg size and increased in consistency. He was admitted to the hospital under the suspicion of prostatic cancer on December 8, 1986. Scout kidney-ureter-bladder X-ray revealed extensive osteolytic lesions in the left iliac and pubic bones as well as in the sacrum. Needle biopsy of the prostate demonstrated moderately differentiated adenocarcinoma, leading to a diagnosis of prostatic cancer with osteolytic bone metastases. Bone scintigraphy showed increased radioactivity uptake by the left iliac and pubic bones. Pelvic CT disclosed large tumor masses in the left ilium and sacrum, which on bone biopsy were identified as poorly differentiated adenocarcinoma. Endocrine therapy with estramustinphosphate and castration was performed along with transurethral resection of prostate. At week 16 after initiating the therapeutic regimen the patient was entirely free from disturbance in gait and the tumor mass of the left iliac bone had disappeared almost completely on the computed tomogram at week 18, although osteolytic lesions still persisted on the x-ray. This case deserves special note because endocrine therapy markedly reduced the size of the bone tumors, in spite of osteolytic bone metastases of prostatic cancer with computed tomographic evidence of large metastatic tumor masses.

From 1956 to 1985, autopsy was done on 17 lung cancer patients in our hospital. There were two patients with focal metastasis as the presenting symptom without any primary cancer manifestations. One patient was admitted for severe right epigastric pain followed by severe pain in the left epigastrium. The chest film revealed nothing except some indefinite inflammatory lesions in the left upper lung. The patient died of uremia in 6 months. A primary carcinoma of 2 cm in diameter in the left lower lung was found on autopsy, which widely spread to the right lung, ovaries, upper segment of the left ureter, peribronchial and periaortic lymph nodes. Histological diagnosis was poorly differentiated adenocarcinoma. The other patient had destruction of the sphenoid bone with cranial nerve paralysis and hypothalamic syndrome at first. The primary cancer, a poorly differentiated adenocarcinoma of 2 X 3 X 1.5 cm in size, was found in the right upper lung on autopsy. Focal metastatic symptom as the initial presentation of lung cancer is rare. These tumors, as small lesions, frequently occur in the peripheral part of the lung. However, the site in which the presenting symptom develops may not necessarily be the place prone to metastasis. The presenting symptom, in turn, would depend upon the tendency of causing symptoms in the involved site. The author suggests that careful searching and identifying of the pulmonary lesion be routinely done for patients with metastatic carcinomatous symptoms only.

A case of synchronous contralateral renal cell carcinoma and ureteral transitional cell carcinoma is reported. A 56-year-old man, who had been incidentally found to have an abnormal mass in the upper pole of the right kidney on ultrasound sonography, was admitted on January 8, 1985. CT scanning and renal arteriography revealed right renal malignancy. Right radical nephrectomy was performed and histological examination showed adenocarcinoma, granular cell type of the right kidney. He was discharged on February 3, 1985. Two months postoperatively, he was rehospitalized for macroscopic hematuria. Left retrograde pyelogram showed obstruction at middle ureter and cytology of urine from left ureter was positive. So a left ureteral tumor was suspected, and partial resection of left ureter and ureteroureterostomy were performed. Histological examination revealed ureteral transitional cell carcinoma. He is now doing well at 6 months following the lat surgery, without any evidence of recurrence.

The cytologic features of a primary adenocarcinoma of the renal pelvis in a 64-year-old woman are reported. Cytologic examination of voided urine revealed an ordinary papillary pattern, characterized by clumping of cells with nuclear overlapping, eccentric position of nuclei and cytoplasmic vacuolization due to mucus production. Leukocytes and micro-organisms were also present. Multiple lesions of papillary adenocarcinoma were subsequently found in the right renal pelvis and ureter. The histogenesis of the primary adenocarcinoma seemed to be closely related to columnar-cell metaplasia of lining of the renal pelvis of this patient, who had previously been treated for tuberculosis of the urinary bladder.

The 39 cases of renal pelvic and ureteral tumors treated in our hospital from 1974 to 1983, were reviewed retrospectively. The 39 cases included 15 renal pelvic tumors, 21 ureter tumors and 3 ureteropelvic tumors. The incidence of these tumors was 0.15% among all new outpatients. Sex distribution was 25 males to 14 females, and mean age was 65.2 years old. Hematuria was the most frequent initial symptom and chief complaint. Of the patients, 28.6% had come to our hospital within one month after their initial symptoms appeared. "Filling defect", an important finding of IVP and RP, was revealed most frequently. The positive rate of urine cytology was 33.4%. Histological examination revealed 14 transitional cell carcinoma and 1 papilloma of 15 renal pelvic tumors and 19 transitional cell carcinoma, 1 polyp and 1 metastatic adenocarcinoma of 21 ureter tumors. Operative therapy was performed on 36 patients; 26 by nephroureterectomy with partial cystectomy. Vesical recurrence rate was 18.9%. The 5-year survival rate was 37.4% on renal pelvic tumor and 40.7% on ureter tumor. The factors, high grade, high stage, and ureteropelvic double tumor, which reflect the specificity of the malignant potential, also affected prognosis. In conclusion, post-operative adjuvant therapy was thought to be valuable in the near future.
