FIG5
Histopathological examination of lymph node biopsy demonstrated non-caseating granulomatous inflammation, and cells diagnostic of malignancy were not identified (Figures 5, 6).
Pathology images (20x). Pathology images show multiple non-necrotizing granulomas composed of aggregates of epithelioid histiocytes with multinucleate giant cells of the Langhans type (yellow arrows) and foreign-body type (red arrow), and lymphocytes. Grocott methenamine silver (GMS) and acid-fast bacilli (AFB) stains are negative.
