Immune system plays crucial role in body and lymph nodes are essential parts of this system for combating pathogens. However, no study has ever been conducted on morphometric development of sheep lymph nodes in fetal period. Thus, this study attempted to examine the morphometric characteristics of a number of important lymph nodes of some lymphocenters of sheep during fetal period. To this end,...

Background: Cervical cancer is the second most common type of cancer among women. Effective screening programs can help cancer detection in early phases and reduce death. Metastasis to lymph nodes is one of the most prognostic factors in patients who underwent surgery. Also, a positive result from pathology report alert oncologist as a cause of death. Sentinel lymph node biopsy has been widely ...

clinically apparent cervical lymphadenopathy has been found at the initial presentation in 23 to 56 % of cases of papillary thyroid carcinoma. here we report tuberculous lymphadenitis mimicking metastatic lymph nodes from papillary thyroid carcinoma and suggest that tuberculosis apart from metastasis in papillary thyroid carcinoma should also be considered in the etiology of enlarged lymph node...

a 19-year-old girl referred to our clinic complaining of a painless lump on the left side of her tongue.  the patient had no history of dysphagia, lingual paresthesia or bleeding. physical examination revealed the presence of multiple enlarged lymph nodes on the left side of her neck.  histopathology of lingual mass and lymph nodes showed pleomorphic adenoma.  to our knowledge, this is the firs...

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...

meningioma is usually a benign central nervous system (cns) tumor. metastasis is rare; however if it does occur the most metastatic sites are the liver and lungs. here, two cases of cns meningioma with metastasis to cervical lymph nodes are reported. the first case, a 48 year-old man developed cervical lymph node metastasis nine years after primary tumor diagnosis. the second case, a 23 year-ol...

conclusion gray scale sonography in combination with doppler sonography could be a trustworthy technique in differentiating metastatic lymph nodes from reactive ones. although, circulation pattern had a higher diagnostic accuracy in the present study, combination of sonographic characteristics could be more beneficial in differentiating metastatic cervical nodes from reactive ones. results the ...

Introduction: To assess the rate of cervical lymph node involvement in patients with supraglottic squamous cell carcinoma (SCC) with no lymph node in clinical assessments and radiological studies. Materials and Methods: Fifty-six patients who underwent elective dissection of the cervical lymph node of the second through fourth level were enrolled, and pathologic evaluation of the dissected lymp...
