Lung, Metastatic Carcinomaالـرئة ســـــرطان
The lung tissue has been replaced by large sheets of malignant cellsThe sheets is formed of pleomorphic cells with hyperchromatic nucleiThere is also extensive necrosisThe characteristic architecture of the residual normal lung can be seen.
Lipoma
mature white fat cells The nucleus
Schwannoma
The tumor shows a mixture of two growth patterns:
-In the Antoni A pattern of growth, elongated cells with cytoplasmic processes are arranged in fascicles in areas of moderate to high cellularity with little stromal matrix. The nuclear palisading can be seen.
- In the Antoni B pattern of growth, the tumor is less densely cellular with a loose meshwork of cells along with microcysts and myxoid changes.
In both areas, the cytology of the individual cells is similar, with elongated cell shape and regular oval nuclei
