Summary
This study reports a rare case of spinal cord germinoma in a 33-year-old woman. The tumor exhibited characteristic features and strong c-kit expression, leading to neurological deficits despite treatment.
Area of Science:
- Neuro-oncology
- Pathology
- Neurosurgery
Background:
- Spinal cord tumors are rare, with germinomas being an uncommon subtype.
- Intramedullary spinal cord tumors present diagnostic and therapeutic challenges.
Observation:
- A 33-year-old woman presented with progressive numbness in lower extremities extending to the thorax.
- Magnetic resonance imaging revealed an intramedullary spinal cord mass with heterogeneous enhancement and peritumoral cysts at T1-T3 levels.
Findings:
- Intraoperative and histological examination confirmed a spinal cord germinoma with a "two-cell pattern".
- Tumor cells displayed strong surface c-kit protein expression.
- Surgical debulking followed by chemotherapy and radiation therapy resulted in partial neurological improvement.
Implications:
- This case highlights the importance of considering germinoma in the differential diagnosis of intramedullary spinal cord lesions.
- Strong c-kit expression may have implications for targeted therapy in spinal cord germinomas.
- Multimodal treatment approaches are crucial for managing these rare tumors.

02:38Mitogens and the Cell Cycle
Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
01:33Cancer-Critical Genes I: Proto-oncogenes
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

01:20The Retinoblastoma Gene
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

01:06Induced Pluripotent Stem Cells
Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).
