Histopathological examination of the biopsy specimen indicated small round atypical cells with narrow cytoplasm and hyperchromatic nuclei constituting solid layers (Figure 3a). Histochemical examination revealed Periodic Acid-Schiff (PAS) positive intracytoplasmic perinuclear eosinophilic globular accumulations (Figure 3b). MAB-0266), while pneumocytes were significantly marked (Figure 3c). MAB-0256) (Figure 3d) and also membranous with CD 99 (mouse anti-CD99 monoclonal antibody; cat. no. MAB-0059) (Figure 3e) and cytoplasmic with vimentin (rabbit anti-vimentin monoclonal antibody; cat. no. RMA-0547) (Figure 3f), respectively.
