Histological examination performed on the mass revealed a lobulated neoplasm composed of large polygonal cells replaced the last coccygeal vertabra. The neoplastic cells had highly vacuolated cytoplasm (physaliferous cells) and intracytoplasmic Periodic Acid-Schiff-positive granules. Immunohistochemistry revealed cytoplasmic positivity for cytokeratin, vimentin and S-100. Histomorphological features and immunohistochemical results consistent with a chondroid chordoma of humans. This case report described Histomorphological features and immunohistochemical results in chondroid chordoma located at the tail of Anglo mink, and reviews the relevant literature, which can provide a reference for the diagnosis and prognosis of the tumor.
