Pathology dictionary -
All organs include a special type of tissue called stroma which provides both functional and structural support for the organ. Myxoid is a word pathologists use to describe a change in the way the stroma looks under the microscope. Myxoid stroma looks more blue compared to normal stroma which looks pink.
The presence of myxoid tissue offers a clue to the diagnosis but it is not a diagnosis in itself. However, some types of tumours are always associated with a myxoid stroma and the word myxoid (or ‘myxo’) may be included in the diagnosis.
