Pathology Image Detail

Caption

The neoplasm is composed of papillary projections (predominantly in this area) and a few glands supported by a small amount of fibrovascular stroma. Papillae and glands are lined by a one cell-thick cuboidal epithelium. Neoplastic cells are cuboidal with indistinct cell borders and a small to moderate amount of strongly amphohilic cytoplasm. Small aggregates of degenerated neoplastic cells are scattered between neoplastic papillae.
