A patient with colic and hematuria from renal involvement with osteogenic sarcoma who was palliated by percutaneous arterial embolization is described. While there has been much experience with embolization of primary renal tumors, this represents the first reported case of therapeutic embolization of a secondary renal tumor. Embolization is recommended as an adjunct to chemotherapy in the poor-risk patient with a symptomatic secondary renal tumor.

Right renal agenesis, ectopia, or anterior nephrectomy can be identified by a characteristic malposition of the right colon. Barium enemas show that the posterior portion of the right colic (hepatic) flexure occupies the area of the right renal fossa. This change in position of the right colon was not observed as a normal variant in 100 randomly selected patients but was present in each of eight patients with agenesis, ectopia, or anterior nephrectomy. This malposition should not be mistaken for internal hernia, malrotation, or displacement by tumor mass or organomegaly. Nonvisualization of the right kidney on excretory urography with normal position of the colon excludes agenesis or ectopia as diagnostic considerations.

The clinical presentation and roentgenographic findings of renal cell carcinoma have been consistently variable. These patients can appear with flank pain mimicking ureteral colic, flank tumors, or symptomatic metastasis [1]. Systemic cardiac manifestations including cardiomegaly with congestive heart failure due to arteriovenous fistula formation have been reported [2] Roentgenographic findings may show the tumor to be either vascular or avascular. It may present as a spontaneous perforation of the pelvic ureteral system which is demonstrated by intravenous pyelography (3). In this article, we describe a case of hypernephroma in a cyst wall causing severe spontaneous hemorrhage in the retroperitoneal space resulting in a state of hypovolemic shock.

18 patients were admitted from 1969 to 1973 to the Surgical and Urological University Clinic in Mainz with ruptured infrarenal aortic aneurysms. Three patients died immediately following the operation and three during surgery from internal hemorrhage. Eight patients died later following prolonged shock. Four patients survived surgery. The classical symptoms of shock, abdominal pain and pulsating tumor was only present in three patients. The diagnosis was only made in seven patients at admission, from the clinical findings. Urological symptoms were also prominent such as unilateral flank pain, colic, dysuria, anuria and tenderness over the kidney. There is no typical clinical picture of ruptured aortic aneurysm. Acute urological symptomatology in cases of acute abdomen with unclear etiology and in connection with shock could indicate a ruptured aortic aneurysm. There is absolute indication for immediate operative intervention. The aneurysm is removed and replaced by a vascular prosthesis. Early diagnosis is important since prolonged shock and anuria will result in a poor postoperative prognosis. Abdominal exploration is therefore also indicated when a ruptured aortic aneurysm is only suspected.

The problems arising from the discovery of a colorectal tumor during an infectious endocarditis caused by Streptococci D have rarely been mentioned in the surgical literature. The frequency of association of an asymptomatic colorectal tumor and of a Streptococcus bovi endocarditis is now undisputed. This notion implies the systematic search for an intestinal lesion (adenoma or carcinoma) in case of endocarditis or septicemia without involvement of the valves, caused by a streptococcus of group D. The authors report about 3 cases of enterococcal (1 case) and S. bovis (2 cases) infectious endocarditis revealing a colic adenocarcinoma (2 cases) and a villous adenoma (1 case), all being perfectly latent. The specific therapeutic problems arising from this association are outlined, including the antibiotic therapy, the role of the anticoagulant treatment and the priority given to valve surgery in case of hemodynamic instability.

Plain abdominal X-rays of a 13-year-old girl with chief complaints of back pain revealed calcification in the upper left abdomen. A calcified tumor was confirmed at the dorsal side of the pancreatic tail upon admission. A completely formed colic membrane free of all other germ layers was discovered within the tumor, leading to a diagnosis of heterotopic colonic membrane. To our knowledge, there have been no other cases of heterotopic intestinal tissue of this type, so we consider this an extremely rare case worth reporting.

Eighty consecutive patients presenting with complete large intestinal obstruction from primary carcinoma were evaluated. A multivariate analysis was performed to evaluate perioperative morbidity and mortality. There were five deaths in the immediate postoperative period (30 days). Extensive and lesser complications occurred in eight and 11 patients, respectively. There were 25 lesions of the right colon, whereas in 55 patients, the lesion was located distal to the left branch of the middle colic artery. Females were more likely to present with obstructed carcinomas of the left colon than males. Patients with an obstruction of the left colon more frequently presented with dehydration than those with a tumor of the right colon (p less than 0.05). Most carcinomas of the right colon were resected, whereas lesions of the left colon were managed with diverting colostomy in 33 patients and by primary resection in 22. Thirteen patients with carcinomas of the left colon had an immediate anastomosis without mortality. Preoperative severe cardiopulmonary disease, Acute Physiology and Chronic Health Evaluation score and advanced carcinoma (Dukes' C or D) were statistically related to early hospital morbidity and mortality, while individual physiologic parameters, site of lesion or operation performed were not. Primary resection may be performed safely in selected patients. Multivariate assessment and clinical staging may allow for appropriate patient selection and improve immediate outcome.

A large fibrotic mass originating from the cecal base was discovered upon surgical exploration of the abdomen in a Thoroughbred mare with a history of chronic colic and weight loss. The mass protruded intraluminally resulting in partial obstruction. Surgical excision was not feasible due to the location of the mass and the inability to exteriorize it adequately from the abdominal cavity. The mass was fibrous with a shiny, gelatinous material present throughout the neoplasm. Histologically, large confluent spaces filled with mucopolysaccharides were identified by staining with Alcian blue. The diagnosis of myxosarcoma was based upon finding of atypical fibroblastic cells, mucinous stroma, local invasiveness, and metastasis to the regional lymph nodes. Myxomatous tumors have not previously been documented to occur in the equine intestinal tract.

A total of 119 Japanese patients with pancreas head carcinoma were treated in the Department of Surgery I, Kyushu University Faculty of Medicine, Fukuoka, Japan, from January 1976 to December 1991. Three of the 119 patients had carcinoma in the uncinate process, with a 2.5% incidence of pancreas head carcinoma. Those three cases consisted of two men, one 55 and one 72 yr old, and one 62-yr-old woman. Two patients developed abdominal pain, whereas another was vomiting; no patients were icteric. Hypotonic duodenography showed an irregular mucosa of the inner area of the third portion of the duodenum in two and an obstruction of the duodenum in one. Drip infusion cholangiography and/or endoscopic retrograde cholangiopancreatography revealed no abnormality of the biliary tract or pancreatic ducts in any of the three. Ultrasonography showed a hypoechoic mass in the uncinate process in three, and computed tomography showed a low-density mass in the uncinate process in two with a displacement of the superior mesenteric vessels toward the anterior. Angiography showed encasement of the pancreatoduodenal arcade in three, the dorsal pancreatic artery in two, and the middle colic artery in two. No neovascularity or tumor staining was present. Two patients underwent a pancreatoduodenectomy, and the other had a bypass operation (gastrojejunostomy). The histopathologic diagnosis was well-differentiated adenocarcinoma, mucinous carcinoma, and adenosquamous carcinoma, respectively. Two patients died from local recurrence and/or distant metastasis 5 and 6 months after a radical resection, and the other died 3 months after clinical diagnosis. Peculiar clinicopathologic features of these patients with pancreas carcinoma arising in the uncinate process are reported herein, and the clinical problems of this disorder are briefly discussed.
