Macroscopic findings and histopathological findings. a, b Mass in the left diaphragm was 68 mm in size, and the cut surface showed yellow content covered with a thick wall. c Conventional hematoxylin- and eosin-stained section of lung tissue adhered to the tuberculoma showed epithelioid cell granulomas composed of histiocytes and multinucleated giant cells (white arrow heads). Bar: 100 µm. d Adhesion was present between the tuberculoma and left lower lung. Bar: 1 mm. e Histiocytes and multinucleated giant cells (black arrow heads) were found in the diaphragmatic muscular layer (white arrow heads). Bar: 50 µm
