Definition
- Noun:
- A type of refractory anemia characterized by the presence of sideroblasts in the bone marrow: "Siderochrestic anemia" is a medical term for a rare blood disorder where the body has sufficient iron but cannot incorporate it properly into hemoglobin within red blood cells. This leads to anemia that is typically resistant (refractory) to standard treatments. The defining feature is the presence of abnormal, iron-loaded red blood cell precursors called "ringed sideroblasts" in the bone marrow.
Usage Examples
- Noun:
- The patient's fatigue and pallor were eventually diagnosed as siderochrestic anemia.
- A bone marrow biopsy is essential to confirm siderochrestic anemia by identifying ringed sideroblasts.
Advanced Usage
- "Refractory siderochrestic anemia": This term emphasizes the condition's typical resistance to common therapies like iron supplements or vitamins.
- Managing refractory siderochrestic anemia often requires specialized hematological care.
