LYMPH NODES - TUBERCULOSIS

Clinical History

This patient was a young woman who presented with a history of lumps in the neck which had been present for 4 years. The lumps had recently enlarged and become firmer.

Pathology

The specimen consists of five masses of lymphoid tissue. The individual lymph nodes are enlarged and some are matted together. Some of the nodes contain discrete white areas which are foci of caseous necrosis. Microscopy revealed chronic granulomatous inflammation with focal necrosis and multinucleated Langhans type giant cells. Ziehl Neelsen stain revealed acid-fast bacilli. Lymph node culture confirmed the diagnosis of tuberculosis.
