A Pathological results for posterior RB2. Granulomatous inflammation. Under the microscope, lymphocyte infiltration was noted, and individual multinucleated giant cells were observed. Special staining results: acid-fast 1 (−), acid-fast 2 ( +), Gram (−), Grocott methenamine silver (GMS) (−), periodic acid-Schiff (PAS) (−), acid-fast fluorescence ( +), fungal fluorescence (−). B, C Results of mNGS detection in specimens obtained by percutaneous lung puncture. These results show the specific fungal sequences of Exophiala dermatitidis and other suspected respiratory/skin flora. D Comparison of the number of mNGS reads detected in the two biopsy specimens
