Renal cell carcinoma represents the 16th cause of death by cancer. It is one of the most frequent kidney tumors. This tumor could behave as a good mimicker, and is frequently associated with paraneoplastic syndromes. Metastases to peritoneum, mesentery or omentum are very rare. Sarcomatoid renal cell carcinoma is a high-grade undifferentiated component that can be found in any subtypes of renal cell carcinoma, and is associated with an aggressive behavior and a poor prognosis. We present the case of a 59-year-old male, diabetic patient, with nephron preserved left nephrectomy through lumbotomy seven years ago, upper pole renal carcinoma, admitted to the emergency department with indeterminate shock. He underwent a diagnostic laparoscopy and then open surgery due to findings where a greater omentum subtotal infarction. Omentum microscopic examination resulted in vaguely differentiated neoplasia, with sarcomatoid like cells, highly positive to CD10 inmunolabeling. Even though renal cell carcinomas have unusual clinical presentations, this case is unique because of the convergence of extremely rare manifestations such as the combination of malignant ascites, peritoneal carcinomatosis, and contralateral suprarenal gland metachronous metastases at the major omentum with paraneoplastic syndrome type leukemoid reaction;which have not been reported previously in literature.

Canola and oat forage potential may be affected by climatic conditions when sown *** objective of this study was to evaluate the forage canola and oat potential in four early sowing dates(September 11 and 25;October 9 and 23)during the 2012-2013 and 2013-2014 cycles in Matamoros,Coahuila,*** cycle duration,chemical composition,dry matter(DM),crude protein(CP),and net energy for lactation(NEL)yields were *** temperatures and long photoperiods affected crops seeded on September 11,accelerating growth and reducing canola(26.6%-31.7%)and oat(15.8%)DM *** of September 25,canola cv IMC 205 reached DM yields(7746 kg ha^(-1)-9276 kg ha^(-1))similar to those obtained by oat(8115 kg ha^(-1)-9507 kg ha^(-1)),while canola cv Hyola 401 obtained such yields only until October *** chemical composition was better than that found in oat,with higher CP,but lower acid detergent fiber(ADF)and neutral detergent fiber(NDF)*** equaled oat CP yields(972 kg ha^(-1)-1215 kg ha^(-1))in the first sowing date,while in the other three other canola sowings reached higher yields(1193 kg ha^(-1)-1889 kg ha^(-1)).As for NEL yields,no difference was observed between both *** best sowing date for canola is from September 25 on,with CP production advantages over oat.
