monostotic fibrous dysplasia
Definition
Noun: A benign bone condition characterized by the abnormal development of fibrous tissue within the bone marrow, replacing normal bone. This condition affects only a single bone in the body.
Usage
The term is used in medical contexts to describe a specific, localized form of fibrous dysplasia. It is a diagnostic classification.
Examples
- The X-ray revealed a lesion consistent with monostotic fibrous dysplasia in the patient's femur.
- Unlike the polyostotic form, monostotic fibrous dysplasia is typically found in a single rib or long bone.
- Treatment for monostotic fibrous dysplasia is often conservative unless the lesion causes pain or a risk of fracture.
Advanced Usage
- The term is often contrasted with , which affects multiple bones.
- It may be part of a differential diagnosis when a solitary bone lesion is discovered on imaging.
Variants and Related Words
- Fibrous dysplasia (n): The broader category of the disorder, which can be monostotic (single bone) or polyostotic (multiple bones).
- Polyostotic fibrous dysplasia (n): The form of the disease that involves multiple bones.
Synonyms
- Solitary fibrous dysplasia
- Localized fibrous dysplasia
Notes on Meaning
The condition itself is the same pathological process as polyostotic fibrous dysplasia; the prefix "monostotic" specifies the extent (one bone) rather than indicating a different disease.
Noun
-
fibrous dysplasia of bone confined to a single bone
