While the presence of multiple primary malignancies in the same patient is a well described phenomenon, there is no clear association between various histological subtypes of renal cell carcinoma (RCC) and the synchronous presence of colon malignancies. We present the rare case of an 81-year-old female patient suffering from chromophobe renal cell carcinoma (chRCC) and an angiomyolipoma of her ...

Group G streptococcus has been increasingly reported as a cause of bacteremia and infective endocarditis. The association between various groups of streptococcus with malignancy has been well established. Such association is particularly observed in group D Streptococcus bovis which is commonly reported in association with carcinoma of the colon. We herein report a case of a 72-year-old male wh...

A 70-year-old woman with a history of lobular breast cancer presented to our Outpatient Clinic with diarrhoea for the past 3 years. Clinical examination and laboratory research were normal. Colonoscopy showed diffuse mild erythema and a decreased vascular pattern. Biopsies from the ascending colon, transverse colon, and descending colon showed metastases of lobular breast carcinoma. Although ga...

Recently, we have reported that surgical stress promoted the metastasis of murine colon carcinoma cells to the lung by inducing the expression of proteases such as matrix metalloprotease-9 (MMP-9) in lung tissue. Urinary trypsin inhibitor (UTI) is a serine protease inhibitor frequently used to treat pancreatitis and to improve the microcirculatory environment. The purpose of this study was to i...

Cell surface receptors for laminin may play an important role in tumor migration and metastasis. To evaluate laminin receptor/laminin-binding protein expression in human colon carcinoma, surgical specimens of primary colon cancers and liver metastases were examined by blot hybridization of total RNA with a complementary DNA clone which encodes a Mr 32,000 human laminin-binding protein. The mRNA...

Overall, colorectal cancer is the third most commonly diagnosed cancer in both men and women, meaning that it is one of the more widely recognized preventable cancers. Instances of colorectal malignancies though are overwhelmingly attributable to adenocarcinoma. Colorectal cancers with components of squamous cell carcinoma represent a statistical anomaly. Here, we present the case of a 50-year-...

RATIONALE All the enteric ganglion cells are fully mature by 2 to 5 years of age in human. No one had reported the presentation of immature enteric ganglion cells in elder ones. Colorectal carcinoma is also rare in the adolescent population. The coincidence of these 2 rare events in a 13-year-old boy has never been reported elsewhere, which may suggest some linkage between them. PATIENT CONCE...

A proliferating cell nuclear antigen (PCNA) was identified with autoantibodies from a patient with systemic lupus erythematosus. Specific antibodies were purified by affinity chromatography in which Novikoff hepatoma nucleolar proteins were conjugated to Sepharose-4B. The purified anti-PCNA antibodies produced bright nucleolar fluorescence in tumor cells as shown by indirect immunofluorescence....

dear editors: adenocarcinoma of colon and rectum is the second most common cancer of the gastrointestinal (gi) tract in children. the development of carcinoma of colon in general appears to be associated with several predisposing factors such as familial polyposis, hereditary non-polyposis syndromes, ulcerative colitis, previous ureterosigmoidostomy or radiation therapy and dietary factors (hig...
