ABSTRACT

Objective:

To approach the distinctive histopathological chages of nontuberculous mycobacteria lymphadenitis.

Methods:

The experimental animal model of nontuberculous mycobacteria lymphadenitis was developed and the histopathological changes were observed under the light microscope.

Results:

The distinctive histopathological changes of nontuberculous mycobacteria lymphadenitis were identified as following ①Granulomas were found in lymph nodes which were infected with nontuberculous mycobacteria.The coagulation necrosis was located at the center of the granuloma and it was not caseation.Neutrophils were distributed over the necrosis area.Surrounding the center necrosis area,many epithelioid cells,lymphocytes and mononuclear cells could be found.The periphery of the granuloma was surrounded by the fibrous tissues.Outside the granuloma,Langhans giant cells could be found.②Serpiginous necrosis was found in the lymph nodes which were infected with nontuberculous mycobacteria.The shape of serpiginous necrosis was a long strip.In the center area,the strip of coagulation necrosis and the strip of the space which was remnant after the desquamation of necrosis tissues could be found.Many neutrophils were distributed over the necrosis area.Around the center necrosis area,many epithelioid cells,lymphocytes and mononuclear cells could be found.The fibrous tissues were in the borderline.

Conclusion:

Serpiginous necrosis was one of the distinctive histopathological change of nontuberculous mycobacteria lymphadenitis.
