Differential diagnosis
Lymph node nodules should be distinguished from tuberculosis. The two can be distinguished by the following points:
1 Nodules are small and scattered, unlike tuberculous nodules that fuse into larger lesions, and epithelial nodules involve more than one organ.
2 There are few multinuclear giant cells, and the nucleus is dispersed in the cytoplasm.
There is no lymphocytic infiltration around the nodules, often fibrosis, and the surrounding boundary is clear.
4 no cheese-like necrosis occurred.
