To determine the frequency and distribution of extrahepatic and extraskeletal metastases in patients with breast carcinoma, the abdominal CT scans of 260 consecutive patients were systematically evaluated. Extrahepatic and extraskeletal metastases were demonstrated in 26 patients (10%). Confirmation of findings was made by biopsy, autopsy, or by demonstration of progression or regression of disease. Twelve patients (4.6%) demonstrated metastases to the stomach, eleven of whom presented with a linitis plastica pattern. Retroperitoneal and/or mesenteric adenopathy was noted in 10 patients (3.8%), of whom three demonstrated associated hydronephrosis and one demonstrated associated biliary obstruction. Ascites was seen in 14 (5.4%) and peritoneal carcinomatosis in 7 (2.6%). Genitourinary involvement included metastases to the kidney (one case), ureter (one), and uterus (one). Direct invasion of the diaphragm by adjacent pleural metastases (two cases) as well as a soft tissue metastasis (one case) was also demonstrated. Metastases to the ovaries, adrenals, or pancreas could not be identified. Although lesions to the liver and skeleton account for the largest group of metastases from breast carcinoma seen in the abdomen, one should be aware of the potential for other locations of metastatic disease.

1. Widespread visceral and intestinal wall metastases are present in women dying with ovarian cancer. Intestinal wall invasion is commonly found at autopsy and is associated with bowel obstruction. Liver parenchymal replacement by metastases in more extensive than that in the lung, where most metastases have a subpleural location. Multifocality characterizes metastases in both of these organs. 2. Neoplastic lymphatic invasion is common. Lymphatic and blood vascular invasion are associated with an increased incidence of metastases in lymph nodes, small bowel wall, pancreas, lungs, ureter, and liver. 3. The mean survival time from diagnosis to death is less than 2 years. Both increasing neoplastic histological grade and clinical stage at diagnosis are associated with decreased survival time. 4. The most common causes of death are carcinomatosis, infection, or a combination of these processes. Sepsis, pneumonia, or both of these account for most of the fatal infections. 5. Bowel and ureteral obstruction constitute the most common forms of tumor-induced morbidity. The former process tends to be multifocal, involving the small and large intestines, and it is found during the disease course as well as at autopsy. Ureteral involvement is usually associated with hydronephrosis and is bilateral in approximately one fourth of the cases.

Spontaneous rupture of the right upper ureter caused by metastatic ureteric tumor in an 80-year-old man is reported. He was admitted to our hospital with right lower abdominal pain. Ultrasonography showed mild right hydronephrosis and a low echogenicity mass under the right kidney. Drip infusion pyelography and abdominal computerized tomography showed extravasation of contrast medium around the right upper ureter. Retrograde pyelography was unsuccessful because of edema of the bladder wall. Right ureterocutaneostomy was performed under the diagnosis of spontaneous rupture of the right ureter. The right ureter was completely obstructed 3 cm below the point where it crossed the common iliac artery. At this site, the ureteric wall was hard, thickened, and adherent to the surrounding tissue. The lesion was a metastatic adenocarcinoma. The origin of the tumor could not be found, but pancreatic cancer was suspected on the basis of elevated CEA and PSTI levels. He died of peritonitis carcinomatosis at 8 months after surgery. Thirty three cases of spontaneous rupture of the ureter and 60 cases of metastatic ureteric tumor have been reported in Japan. However, our patient is the first reported case of spontaneous rupture of the ureter caused by a metastatic ureteric tumor in the Japanese literature.

This report describes the case of a patient with peritoneal carcinomatosis due to recurrent adenocarcinoma of the ureter who was chemo-sensitive to weekly paclitaxel. A 73-year-old man was admitted to our hospital for pain in the right back in September 2009. Drip infusion pyelography(DIP)showed right hydronephrosis. Cytologic examination of the urine revealed many carcinoma cells in the urothelial tract. The patient underwent right nephroureterectomy, and examination of the resected specimen revealed a primary enteric-type adenocarcinoma of the ureter. Six months after surgery, he visited our hospital because of abdominal pain and distension. Abdominal computed tomography(CT)showed massive ascites. Cytologic examination of the ascitic fluid revealed many adenocarcinoma cells resembling those of the primary lesion. The patient received chemotherapy with S-1 as first-line treatment; however, he experienced severe anorexia and diarrhea. Subsequently, the patient received chemotherapy with uracil/tegafur(UFT)but abdominal distension worsened. Next, he received chemotherapy with weekly paclitaxel(80mg/m2 on days 1, 8, and 15, every 4 weeks). Thereafter, the ascitic fluid disappeared rapidly. After 6 courses of treatment with paclitaxel, abdominal CT revealed no ascitic fluid collection. The treatment was discontinued because of sensory neuropathy. Approximately 10 months later, the patient experienced massive ascites again. At 25 months after recurrence, he died of peritoneal carcinomatosis.

The imaging finding of omental cake has been demonstrated in other modalities, such as computed tomography, magnetic resonance imaging, and ultrasonography. However, to the best of our knowledge, the image presentation of omental cake on a routine kidney-ureter-bladder film has not been reported before in the literature. We presented a unique case of a 61-year-old woman, with known advanced cecal colon mucinous adenocarcinoma, presented to our institution with abdominal fullness, poor appetite, and decreased stool passage for 20 days. Physical examination was unremarkable, except distended abdomen. Subsequent study revealed massive post-pigtail catheter drainage ascites with a prominent soft-tissue mass-causing centralization and tethering of focally distended small bowel gas, suggestive of omental cake on plain radiograph. The imaging finding in plain radiograph corresponds to the findings in other imaging modalities, including abdominal sonography and computed tomography. The patient underwent subtotal colectomy and ileostomy during later courses of chemotherapy due to adhesion ileus and possible intraabdominal abscess, and pathologic study confirmed the diagnosis of cecal mucinous adenocarcinoma and peritoneal carcinomatosis. Although the image finding of omental cake on plain radiograph has never been described, this image finding is unique and should be recognized, as it may suggest the presence of omental cake when first identified in the emergency department from patients with abdominal distension and warrant further evaluation to evaluate the underlying cause.

BACKGROUND Plasmacytoid is a rare histological variant of urothelial carcinoma (UC). Since the first reported case of plasmacytoid urothelial carcinoma (PUC), in 1991, only about 100 cases have since been reported, with most cases involving the bladder. Urothelial carcinomas of the upper urinary tract represent only 5% of urothelial cancers. To the best of our knowledge, there has only been 1 reported case of PUC of the ureter. PUC is a highly aggressive disease, with a poor prognosis. We present a rare biopsy-proven case of PUC of the ureter with retroperitoneal metastasis. CASE REPORT A 60-year-old man came into the hospital with complaints of a 5-day history of generalized abdominal pain, nausea, and vomiting, with no associated urinary symptoms prior to admission. CT demonstrated small bowel obstruction (SBO) and obstructive uropathy due to a right ureteric mass. Exploratory laparotomy, small bowel resection, gastrostomy tube placement, and umbilical hernia repair were all done. Histology and immunohistochemistry were compatible with plasmacytoid variant of urothelial cancer. He underwent a cystouretoscopy and a right ureteral stent placement with a right ureteroscopy. Final CT abdomen/pelvis revealed recurrent SBO before the ileocecal valve, possibly due to carcinomatosis. Ileocecal resection with end ileostomy placement was done. Systemic treatment will begin as an outpatient. CONCLUSIONS PUC arising from the ureter is rare, and retroperitoneal metastatic disease has not been reported previously. Here, we compare the clinical manifestations of the more common PUC of the bladder with our case. From this we are able to learn more about the disease and its presentation.

Krukenberg tumors from pulmonary adenocarcinoma represent an extremely rare situation; only a few cases have been reported. The aim of this paper is to report an unusual such case in which almost complete dysphagia and ureteral stenosis occurred. The 62-year-old patient was initially investigated for dysphagia and weight loss. Computed tomography showed the presence of a thoracic mass compressing the esophagus in association with a few suspect pulmonary and peritoneal nodules, one of them invading the right ureter. A biopsy was performed laparoscopically on the peritoneal nodules. The right adnexa presented an atypical aspect; right adnexectomy was also found. The histopathological and immunohistochemical studies confirmed that the primitive origin was pulmonary adenocarcinoma. Although both peritoneal carcinomatosis and ovarian metastases from pulmonary adenocarcinoma represent a very uncommon situation, this pathology should not be excluded, especially in cases presenting suspect pulmonary lesions.
