Pulmonary and extrapulmonary tuberculosis.

Pulmonary tuberculosis: primary tuberculosis, usually asymptomatic, represents the first infection and is shown by a parenchymal mostly mid-pulmonary focus and satellite lymphadenopathy. Postprimary pulmonary tuberculosis, mostly located in the upper fields may be caused by endogenous reinfection for reactivation of a hematogenous focus formed during primary infection or from exogenous reinfection. Extrapulmonary tuberculosis: it includes numerous forms mostly from hematogenous spread. Miliary tuberculosis may involve a number of organs and apparatus besides the lung. Tuberculous meningitis predominantly involves the base of the skull, the fluid is clear with hypoglycorrhachia and lymphocyte pleocytosis. Lymph node tuberculosis is generally unilateral and cervical. Tuberculous pleuritis is exudative or dry. Other forms of tuberculous serositis are pericarditis and peritonitis. Renal tuberculosis involves the medullaris and intestinal tuberculosis the ileocecum; tuberculous spondilitis (Pott's disease) involves the last dorsal vertebrae. Other forms are osteoarthritis, genital tract tuberculosis, pancreatitis, laryngitis, otitis.

Pulmonary malakoplakia coexistent with tuberculosis of the hilar lymph node mimicking malignancy.

Pulmonary malakoplakia is a disease that is difficult to diagnose because its symptoms vary from those mimicking bronchogenic carcinoma to pneumonitis-like tuberculous infections. Malakoplakia is an unusual inflammatory condition characterized by the accumulation of macrophages with diagnostic Michaelis-Gutmann bodies. In this study, an immunocompromised patient with a tumor mass in the upper lobe of the right lung coexisting with hilar node enlargement is presented. A thoracoscopic biopsy revealed pulmonary malakoplakia with tuberculosis of the hilar lymph node. Microbiologic cultures were positive for acid-fast positive bacilli from the hilar node specimen, and negative for any other microorganisms such as Rhodococcus equi, but positive for Escherichia coli from the lung specimen. The significance of these findings and the coincidental association between malakoplakia and tuberculosis are discussed.

Sarcoidosis and giant midesophageal diverticulum.

Traction diverticula of the midesophagus result from granulomatous inflammation of mediastinal lymph nodes. Tuberculosis and histoplasmosis are known etiologies of this condition. To the best of our knowledge, this is the first report of a traction diverticulum caused by sarcoidosis.

Histiocytic necrotizing lymphadenitis.

Eleven cases of histiocytic necrotizing lymphadenitis were studied. Originally four were misdiagnosed as cervical tuberculous lymphadenitis. The characteristic symptoms and signs were local tenderness, fever, leucocytopenia and good prognosis. Antibody to Epstein-Barr virus was elevated in 2 of 3 cases. Biopsy of the affected lymph node was necessary when the differential diagnosis from lymph node tuberculosis or malignant lymphoma could not be made. The characteristic histological feature was focal necrosis without neutrophil infiltration in cortical or subcortical areas. Ultrastructurally, we found characteristic inclusions ('tubulo-reticular structures') in histiocytes and lymphocytes.
