Sometimes its complete resection is not possible because of vicinity of the mass to important vascular and neural structures.</p> <p><strong>Clinical case: </strong>This is a 56-year old female subject who developed headache in the right side, paresthesia in the right side of her upper lip, short term memory loss, and ageusia. A magnetic resonance imaging study showed an enhanced extra-axial mass. This patient underwent complete surgical resection. The anatomopathological study showed a well differentiated chondrosarcoma of the cranial base.</p> <p><strong>Conclusion: </strong> Chondrosarcoma is a malignancy with pure differentiation of the hyaline cartilage. It represents 0.15% of all intracranial tumors, and this is the second case with a cranial base location reported in Peru. Both histological characteristics and immunohistochemistry markers revealed the classic characteristics of this tumor. Therapy is given on an individualized basis.</p&gt;}, number={3}, journal={ACTA MEDICA PERUANA}, author={Romero Yauri, José and Castillo Gutierrez, Alejandro Esteban and Castillo-Soto, Ana}, year={2021}, month={Oct.} }
