Figure 2: (a-c) Ewings sarcoma/primitive neuroectodermal tumor of the mediastinum showing sheets of dyscohesive small round blue cells with scant cytoplasm, round nucleus with stippled nuclear chromatin (a : MGG stain × 100; b: Papanicolaou stain × 100). PAS stain showed cytoplasmic positivity in tumor cells (c : PAS stain × 400). (d-f) Anaplastic carcinoma of lung showing dyscohesive singly scattered cells with bizzare nucleus (d: Papanicolaou stain ×100; e: Papanicolaou stain ×200; f: MGG stain ×200). (g-i) Plasmacytoma of the lung showing sheets and single scattered of plasma cells and plasmablasts (g: MGG stain ×100; h-I: MGG stain ×400)
