A total of 43 episodes of tuberculosis lymphadenitis were treated in 32 adult patients. In 12 instances the affected lymph node was excised without any chemotherapy; there were 10 relapses. The treatment was local excision of the affected lymph nodes together with antituberculosis chemotherapy with at least two drugs in 30 instances; there were no relapses following such therapy.Presumably pati...

In this review, representative types of granulomatous lymphadenitis (GLA) are described. GLA can be classified as noninfectious GLA and infectious GLA. Noninfectious GLA includes sarcoidosis and sarcoid-like reaction. The cause of sarcoidosis remains unknown, but it has good prognosis. Sarcoid-like reaction, which is considered to be a biological defense mechanism, is observed in regional lymph...

Mediastinal lymphadenopathy in patients with malignancy may not be always metastatic disease. We present three patients with proven thoracic or extra thoracic malignancies with mediastinal lymphadenopathy which were subsequently proven as granulomatous lymphadenitis by endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA). The objective of the current report is to emphasi...

Cat scratch disease is a non-epidemic infection caused by Gram negative bacillus Bartonella henselae. The most common course of the disease includes regional lymphadenitis and skin papule at the entrance site of the infection. We report a case of a female, 22 years of age, with cat scratch disease. Clinically we observed the typical skin papule at the entrance site of the infection with severe ...

In three pediatric patients with necrotizing lymphadenitis, cytosol aminopeptidase activity (c-AP; EC 3.4.11.1) in serum was markedly increased to 509, 417, and 191 U/L, respectively (normal range 25-60 U/L). Lactate dehydrogenase (LD; EC 1.1.1.27) was also increased, with LD-3 predominating. The increased concentrations of c-AP and LD presumably originated from the destruction of infected, act...

Histiocytic necrotising lymphadenitis is the pathognomonic histological appearance of lymph nodes in Kikuchi's disease, a condition characterised by a brief systemic illness and lymphadenopathy. The case is described of a young man, originally diagnosed as having Kikuchi's disease by lymph node histology, who subsequently developed systemic lupus erythematosus with symmetrical polyarthritis, Co...

Kikuchi’s disease (KD), or histiocytic necrotizing lymphadenitis, is a rare benign and self-limited disease involving young adults, predominantly females. It is rarely described in children. It is characterized by localized lymphadenopathy, often associated with fever and systemic symptoms. The diagnosis is based on histological examination of lymph node biopsy. The disease usually resolves spo...

3-Hydroxy-3-methyl-glutaryl-CoA reductase (HMGR) is a key enzyme in the sterol biosynthesis pathway, but its subcellular distribution in the Trypanosomatidae family is somewhat controversial. Trypanosoma cruzi and Leishmania HMGRs are closely related in their catalytic domains to bacterial and eukaryotic enzymes described but lack an amino-terminal domain responsible for the attachment to the e...

Functional cloning led to the isolation of a novel methotrexate (MTX) resistance gene in the protozoan parasite Leishmania. The gene corresponds to orfG, an open reading frame (ORF) of the LD1/CD1 genomic locus that is frequently amplified in several Leishmania stocks. A functional ORF G-green fluorescence protein fusion was localized to the plasma membrane. Transport studies indicated that ORF...
