Definition
Noun: A myxoma is a benign (non-cancerous) tumor composed of connective tissue. Its distinctive characteristic is that it contains a soft, gelatinous, or jelly-like material.
Usage
The word "myxoma" is a medical term used specifically in pathology and oncology to classify a type of soft tissue tumor. It is typically used in clinical descriptions, diagnoses, and medical literature.
Examples
- The biopsy revealed a myxoma in the patient's left atrium, requiring surgical removal.
- Under the microscope, the pathologist identified the classic stellate cells embedded in the mucoid matrix of the myxoma.
- Cardiac myxomas are the most common primary tumors of the heart.
Advanced Usage
- "Atrial myxoma": This is the most frequent type, specifically located in the upper chambers (atria) of the heart. It can cause symptoms like shortness of breath or embolic events.
- "Cutaneous myxoma": Refers to a myxoma found in the skin or subcutaneous tissue.
- The term is often modified by its anatomical location (e.g., , of the jaw).
Variants and Related Words
- Myxomatous (adjective): Describing tissue that has the characteristics of a myxoma (e.g., a of a heart valve).
- Myxosarcoma (noun): A malignant (cancerous) tumor with similar jelly-like material, representing the rare malignant counterpart.
Synonyms

- Mucinous tumor (in specific contexts, though this is a broader category)
Notes on Meaning
While "myxoma" strictly refers to a benign neoplasm, in clinical practice, the location is critical. A cardiac myxoma, though benign, can be life-threatening due to its position, potentially obstructing blood flow or causing strokes.
