Tuberculosis of parotid lymph nodes is a rare condition. Although uncommon, it must be included in differential diagnosis of a discrete parotid gland swelling or mass. Early recognition of the disease entity and awareness of its potential existence can spare the patient unnecessary surgical intervention. A 13-year-old female patient presented with a painless swelling in left preauricular region...

Mast cells are one of the main inflammatory cells involved in the pathogenesis of tuberculosis. Previous reports revealed that mast cells participated in both acute and chronic states of infection with Mycobacterium tuberculosis through direct contact or indirect enhancement by releasing mediators. The authors evaluated mast cell density on tissue sections of tuberculous lymphadenitis stained w...

During drug treatment of tuberculous lymphadenitis, paradoxical response (PR) may occasionally occur. Continued treatment or lymph node aspiration improves PR without severe sequelae. However, we report a case of severe PR in a patient with cervical lymph node tuberculosis causing airway obstruction due to retropharyngeal lymph node swelling during antituberculous treatment. Tracheostomy and dr...

Purulent pericarditis is a rare condition with a high mortality rate. We report a case of purulent pericarditis subsequently caused by Candida parapsilosis, Peptostreptococcus asaccharolyticus, Streptococcus anginosus, Staphylococcus aureus, Prevotella oralis, and Mycobacterium tuberculosis in a previously healthy 17-year-old boy with mediastinal tuberculous lymphadenitis. The probable route of...

The purpose of this study was to describe the clinicopathological features of 40 cases of necrotizing non-granulomatous lymphadenitis in Thai patients. The clinical features, histomorphology and special stains were evaluated in 40 Thai patients from the pathology records of King Chulalongkorn Memorial Hospital from January 2001 to December 2003 in those diagnosed as having necrotizing non-granu...

18-Fluoredeoxyglucose position emission tomography and computed tomography (F-18FDG PET/CT) scanning has been useful in the evaluation of malignant disorders and has been extensively used in cancer screening. However, F-18FDG uptake was not found to be specific for cancer diagnosis. Here, we describe increased F-18FDG uptake on PET/CT caused by extensive tuberculous lymphadenitis in a 62-year-o...

We describe here two cases, one male and one female, both age 40 years, with visceral leishmaniasis and HIV-1 co-infection. The female patient had features of Koch's abdomen. The male patient had features of tuberculous lymphadenitis and bilateral pleural effusion more marked on the right side. Both were treated with highly active antiretroviral therapy, antituberculous drugs, antibiotics, anti...

The annual numbers of cases of non-tuberculous mycobacterial lymphadenitis in south east England has increased over the period 1973 to 1993, most notably during the last few years. The most frequent cause is the Mycobacterium avium complex, followed by M malmoense. The reason for the increase is unknown but it could be due to an increased awareness in mycobacterial disease, an external factor s...

Seven children, aged 4 months to 10 years, with bronchial compression due to tuberculous hilar lymphadenitis have been treated surgically since 1974. The indications for surgical treatment were lack of response to chemotherapy and in particular the development of respiratory distress. Excision or curettage of the affected nodes was found to be a safe and sure method of relieving the acute sympt...

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...
