Sinus histiocytosis with massive lymphadenopathy (SHML) is a distinct benign clinicopathological entity, characterized by painless enlargement of lymph nodes due to sinus histiocytosis. Here, we report a case of SHML with diffuse large B-cell lymphoma. A 64-year-old man was admitted to our hospital because of fever. He presented with enlargement of a small cervical lymph node and huge abdominal...

OBJECTIVE This report examines 60 non-cancer patients who underwent a cervical lymph node biopsy, and discusses the value of the cervical lymph node biopsy as a diagnostic tool. METHODS Sixty patients with cervical lymph node enlargement who had lymph node biopsies at the Juntendo University between 2004 and 2007 were examined. The clinical parameters including age, size of the lymph node, wh...

AIM To evaluate factors that influence the diagnostic accuracy of endoscopic ultrasound (EUS)-guided tissue acquisition for lymph node enlargement in the absence of an on-site pathologist. METHODS A retrospective analysis of patients who underwent EUS-guided tissue acquisition for the pathological diagnosis of lymph node enlargement between April 2012 and June 2015 is reported. Tissue acquisi...

nineteen lymph node biopsies, 3 curetting, 15 blood samples obtained from patients with lymphadenitis and high titers of toxoplasma antibodies, and 27 tonsillar tissues removed from patients because of chronic tonsillitis were inoculated intraperitoneally into mice for isolation of toxoplasma gondii. toxoplasms were isolated from 5 lymph node biopsies, one curettage material, 2 tonsillar tissue...

PURPOSE Anthracosis often results in mediastinal nodal enlargement. The aim of this comparative study was to evaluate if it is possible to differentiate endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) proven anthracotic lymph nodes from malignant lymph node enlargement by means of multislice computed tomography (MSCT). METHODS We compared the MSCT findings of 89 e...

BACKGROUND This study aimed to characterize the histopathological pattern of lymph node pathology among Saudi patients and to highlight the age and gender variations of these lesions as base line data. MATERIALS AND METHODS We retrospectively analyzed the data from lymph node biopsy specimens received at the Department of Pathology, King Fahad Hospital, Madinah, Saudi Arabia from January 2006...

schwannomas are benign nerve sheath tumors that originate from any anatomical site. most of the schwannomas are found in the head, neck or limbs. schwannoma arising in a lymph node is extremely rare. we have found only four cases in the review of the literature. we experienced a case of intranodal schwannoma in a perigastric lymph node. a 72 year-old female underwent cholecystectomy due to clin...

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...

Lymph node enlargement is a common medical problem, and in a large number of patients, the causes of lymphadenopathy remain undiagnosed. We report a thorough microbiological analysis of 1,688 lymph node biopsy specimens collected in our bartonellosis reference center. We studied lymph node biopsy samples from patients with suspected regional infectious lymph node enlargement from January 2008 t...
