In patients with the acquired immunodeficiency syndrome, mycobacterial lymphadenitis is characterized by the presence of numerous acid-fast bacilli within histiocytes. In Diff-Quik-stained cytologic preparations of such lymph nodes, performed during intraoperative consultations, the presence of mycobacteria is manifested by numerous negatively staining rod-shaped spaces intracellularly within histiocytes, as well as extra-cellularly in the background. Recognition of these characteristic "footprints," or "negative images," of mycobacteria can facilitate early diagnosis and treatment. The morphological characteristics that help to distinguish between Mycobacterium avium-intracellulare and Mycobacterium kansasii are also described. |
