Pathology Image Detail

Caption

Neoplastic cells occasionally form tubules lined by a one cell-thick cuboidal epithelium. Neoplastic cells show nuclear palissading at the periphery of neoplastic lobules. They are large, polygonal to fusiform, with indistinct cell borders, and with a moderate amount of acidophilic cytoplasm. The nucleus is central, oval to elongated, medium-sized and slightly hyperchromatic.
NOTE: Tubules are commonly present in myoepitheliomas.
