We present a case and review of the literature of well-differentiated sigmoid adenocarcinoma with numerous metastases into pericolic lymph nodes. All positive lymph nodes were small. The authors concluded that there is no clear correlation between nodal size and the likelihood of metastasis in the lymph node, and the status of small lymph nodes must receive special attention by clinicians and p...

Accurate staging of cancers is one of the most important parts of the work up of patients for both prediction of prognosis and determination of the most appropriate treatment. And an essential part of this work up is assessing whether or not there has been lymphatic spread. Current methods include surgical removal of nodes for examination and various types of imaging, ranging from ultrasound to...

Histologic, histochemical. ultrastructural. and radiolabeling characteristics of the microvasculature in regional nodes draining skin allograft sites are described. From 12 to 48 hours after grafting, these nodes show increased vascular permeability and altered lymphocyte traffic pattern. The rapid rise in lymphocyte migration indices and the apparent plugging of intermediate sinuses bylynmphoc...

Imprints or touch preparations were prepared from lymph nodes in 57 cases. Comparison with histological sections showed a high degree of accuracy (94.7%) in diagnosis. They are simple to prepare and no special equipment is needed. They can be a useful adjunct to histologic sections after surgery (JPMA 30:266, 1980).

The effects of short-term simulated microgravity on the lymph dynamics of rat lymph nodes were investigated using a combination of Bollman's cage and head-down tilt (HDT). Efferent lymphatics of the iliac and mesenteric lymph nodes were cannulated for the collection of lymph. There was no significant difference in lymph flow rate from the iliac lymph nodes between non-HDT (control) and HDT rats...

aim : the aim of this study was to comprehensively analyze histopathologic parameters of whipple pancreaticoduodenectomy specimens at taleghani general hospital pathology department. background : the whipple procedure is performed for variety of tumors involving the head of the pancreas, ampulla of vater, common bile duct, or duodenum. patients and methods : records of all cases of whipple panc...

background: the sentinel lymph node (sln) is defined as the first chain node in the lymphatic basin that receives primary lymphatic flow. if the sln is negative for metastatic disease, then other nodes are expected to be disease-free. sln techniques have been extensively applied in the staging and treatment of many tumors, including melanoma, breast and vulvar cancers. this study aims to evalua...

linguatula serrata is a zoonotic parasite with global expansion, particularly in tropical and subtropical areas. the aim of this study was to evaluate the pathological lesions caused by l. serrata in mesenteric lymph nodes (mln) of water buffalo. to study the pathological lesions of nymphal stage in water buffaloes, enlarged and swollen mln were collected and examined. grossly, the mln were swo...

BACKGROUND The incidence of the esophagogastric junction cancer is growing rapidly. The purpose of this study is to clarify the outcome of the ratio between metastatic and examined lymph nodes in esophagogastric junction cancer patients with or without 7 examined lymph nodes. METHODS A total of 3,481 patients who underwent operation are identified from the Surveillance, Epidemiology, and End ...

the present investigation was conducted to study the effects of experimental clostridium perfringens type d enterotoxaemia in teddy goats. clinical signs started to appear after 30 min of experimental infection like anorexia, diarrhea, dehydration, frothing and dyspnea. gross lesions consisted of severe congestion in tissues of varying intensity with enlarged mesenteric lymph nodes while histol...
