Extrafollicular reticulum cells in lymph nodes are heterogeneous. They express cytokeratins, desmin, and/or vimentin as their intermediate filament profile. Using those markers, we undertook an immunohistochemical study of human lymph nodes under various pathologic conditions. Samples included 15 simple reactive lymph nodes, 7 follicular hyperplasia, 1 necrotizing lymphadenitis, 4 tuberculous l...

Kikuchi’s lymphadenitis (KL), also called as histiocytic necrotizing lymphadenitis, is a reactive condition of a lymph node which has a distinct clinical manifestation but unknown etiology. In most of the cases, it presents as a cervical lymphadenopathy mainly in young adults, especially women. It undergoes a self-limiting course within a few weeks to several months. However, unnecessary excisi...

INTRODUCTION Information on the long-term treatment outcome following nontuberculous mycobacterial (NTM) lymphadenitis is very limited. We performed a study to (a) compare cure rates following different initial treatment courses, (b) describe subsequent treatment courses and their outcomes, and (c) determine the occurrence of late sequelae in immunocompetent children with NTM lymphadenitis. M...

BACKGROUND Tuberculous is the leading cause of death worldwide with a large number of deaths occurring in developing countries. Tuberculous lymphadenitis is among the most common presentations of extra pulmonary tuberculous. This study attempts to determine the magnitude of tuberculous lymphadenitis from patients with lymph node aspirate in Gondar University Hospital, Northwest Ethiopia. METH...

BACKGROUND Bacillus Calmette-Guérin (BCG) vaccination is performed as a part of expanded Programme of Immunization (EPI). Suppurative lymphadenitis is the common complication of BCG vaccination. The optimum treatment for this complication is debated. METHODS All cases of BCG lymphadenitis presenting to pediatric surgical service over a 17-year study period were reviewed to determine the optim...

AIMS To formulate evidence based histopathological criteria for the diagnosis of acquired toxoplasmic lymphadenitis, in an area of high tuberculosis prevalence. METHODS Multiple histopathological parameters were assessed in a consecutive sample of biopsies from 68 patients presenting with lymphadenopathy with a duration of less than six months. Serum IgM enzyme linked immunosorbent assay was ...

Cervical adenitis >1.5cm in diameter is the less frequently observed criteria in patients with Kawasaki disease and it is usually found in association with other symptoms during the acute phase. Moreover, the finding of fever and lymphadenitis with intense local signs of inflammation and phlegmon is rarely seen as the initial manifestation of Kawasaki disease. We report the case of a 7-year-old...

BACKGROUND Due to a similarity between the features of lymphoma and the features of tuberculosis, lymphoma may go unrecognized and undiagnosed in patients with tuberculosis. CASE PRESENTATION A 33-year-old Thai man presented to our center with typical clinical manifestations of tuberculous lymphadenitis, with negative tests for both acid-fast bacilli and fungi, and negative polymerase chain r...

BACKGROUND Tuberculous lymphadenitis is next to pulmonary tuberculosis as the most common cause of tuberculosis. Uganda genotype, one of the sub-lineages of Mycobacterium tuberculosis, is the most prevalent cause of pulmonary tuberculosis in Uganda. We here investigate the clinicopathological characteristics of patients with tuberculous lymphadenitis infected with M. tuberculosis Uganda genotyp...

The aim of the study was to determine the optimal duration of treatment for patients with tuberculous lymphadenitis. The Medline database was searched for relevant articles published between 1978-1997. Inclusion criteria were study populations of patients with predominantly cervical tuberculous lymphadenitis in whom the diagnosis had been confirmed bacteriologically and/or histologically, or wa...
