27. Schwannoma

28. 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 A A B B
