  • Spinal Chordoma

    Spinal Chordoma: Definition and Description of Spinal Chordoma: Spinal chordoma is a rare type of tumor that occurs in the spine. It arises from remnants of notochordal cells, which are present during embryonic development. Chordomas typically develop in the vertebrae, particularly in the sacrum at the base of the spine or in the cervical region…

  • Skull Base Chordoma

    Skull Base Chordoma: Definition and Description of Skull Base Chordoma: Skull base chordoma is a rare type of bone cancer that occurs at the base of the skull and the spine. These tumors arise from remnants of the notochord, a structure that is present during embryonic development. As chordomas are slow-growing tumors, they may not…

  • Sacrococcygeal Chordoma

    Sacrococcygeal Chordoma: Definition and Description of Sacrococcygeal Chordoma: Sacrococcygeal Chordoma is a rare type of tumor that arises from the remnants of notochordal tissue, which is part of the embryonic development of the spine. Specifically, this chordoma occurs in the sacrum and coccyx, which are the lower parts of the spine. These tumors are typically…

  • Gastrointestinal Stromal Tumors

    Gastrointestinal Stromal Tumors Definition and Description of Gastrointestinal Stromal Tumors Gastrointestinal Stromal Tumors (GISTs) are a type of tumor that occurs in the gastrointestinal tract, primarily in the stomach and small intestine. They arise from interstitial cells of Cajal or precursor cells, which are part of the autonomic nervous system of the digestive tract. GISTs…

  • Extragonadal Germ Cell Tumors

    Extragonadal Germ Cell Tumors Definition and Description of Extragonadal Germ Cell Tumors Extragonadal germ cell tumors (EGCTs) are a rare type of tumor that arises from germ cells outside the gonadal regions (testes in males and ovaries in females). These tumors account for approximately 1-5% of all germ cell tumors. They can occur in various…

  • Ewing’s Family of Tumors

  • Clival Chordoma

    Clival Chordoma: Understanding, Symptoms, and Treatment Clival Chordoma Definition and Description of Clival Chordoma Clival Chordoma is a rare type of cancerous tumor that primarily arises in the clivus, a bony structure at the base of the skull. Originating from remnants of the notochord, a structure that provides support during embryonic development, these tumors tend…

  • Bilateral Acoustic Neuroma

    Bilateral Acoustic Neuroma Definition and Description of Bilateral Acoustic Neuroma Bilateral Acoustic Neuroma, also known as vestibular schwannoma, is a rare benign tumor that develops on the vestibular nerve, which is responsible for balance. This condition typically affects both ears, leading to a range of auditory and balance-related symptoms. Acoustic neuromas arise from Schwann cells,…

  • Arachnoidal Fibroblastoma

    Arachnoidal Fibroblastoma Definition and Description of Arachnoidal Fibroblastoma Arachnoidal fibroblastoma is a rare type of tumor that occurs in the arachnoid membrane, one of the three membranes that envelop the brain and spinal cord. This tumor is characterized by the proliferation of fibroblasts within the arachnoid layer, leading to the formation of a localized mass.…
