Patients with end stage renal disease (ESRD) ongoing hemodialysis treatment (HD) have more than 10 [6-16] fold increased risk for development of tuberculosis (TB). The tuberculin reaction is sometimes negative; this may be due to an overwhelming infection impairing the immune response. Tuberculous cervical lymphadenitis is the commonest form of nonrespiratory TB. We report herein three dialysis...

An 8-year-old boy developed cervical lymphadenitis four months after an injection of dental anaesthetic. Histology of the lymphatic tissue showed a tuberculoid granulomatous reaction with scanty acid-fast bacilli. Mycobacterium chelonei was isolated in pure culture (NCTC 10882). The patient showed specific skin hypersensitivity to an extract of M. chelonei, but not to that of M. ranae. This is ...

Lymphadenitis is the most common presentation of extra pulmonary tuberculosis, whereas gastrointestinal localization, particularly duodenal involvement, is rare. We report a case of extra pulmonary tuberculosis with association between cervical lymphadenitis and duodenitis with multiple ulcers, not responsive to treatment with protonic pump inhibitors, in a human immunodeficiency virus-seronega...

Kikuchi-Fujimoto disease is a rare, self-limited, histiocytic, necrotizing lymphadenitis first described in Japan in 1972. Necrosis of lymph node tissue is caused by apoptosis and may be virally induced. It commonly presents with cervical lymphadenitis and fever. Despite its low incidence, Kikuchi-Fujimoto disease should be considered in patients with persistent lymphadenopathy. Originally thou...

Caseous lymphadenitis caused by Corynebacterium pseudotuberculosis is mainly a disease of sheep and goats and is of zoonotic importance. The disease has rarely been recorded in cattle and mostly in its superficial form. The present communication deals with an extremely rare case of corynebacterium-induced mesenteric pseudotuberculosis in a cow calf. The gross, cytologic, histopathologic and mic...

Two children with cervical lymphadenitis due to Mycobacterium fortuitum infection are described; both presented with erythema nodosum.

Superior vena cava (SVC) syndrome refers to a medical emergency resulting from compression of the SVC. It requires early diagnosis and treatment, and is usually caused by malignant tumors; rarely, mediastinal tuberculous lymphadenitis can cause SVC syndrome. Here, we present a case study of an immunocompetent 61-year-old woman who presented with acute onset SVC syndrome and was diagnosed with t...
