The chest x-ray revealed right diaphragmatic elevation and a poorly inflated right lower lobe (Figure 1).
Hematoxylin and eosin (H&E) stain of diaphragm sections. (A) The section shows muscle tissue (big arrow) of the diaphragm and granuloma (star) surrounded by adipose tissue (white arrow) close to the serosa (small arrow) of the pleura, at magnification 200x. (B) Granuloma (star) at magnification 400x. (C) Non-caseating granuloma consisting of Langerhans giant cells (big arrow) and epithelioid cells (small arrow), magnification 800x. (D) Myositis with lymphocytic infiltrate (star) of the muscle tissue, already showing destruction of the muscle cells, magnification 800x.

Interestingly, microscopic examination of several diaphragm sections revealed a lymphocytic myositis with granulomatous pleuritis showing multiple non-caseating epithelioid granulomas (Figure 2).
