What is myxoid degeneration mean?

Definition. A degenerative process in which the connective tissues are replaced by a gelatinous or mucoid substance. Supplement. For instance, myxoid degeneration of the tendon occurs when the normal fibrilary appearance of the tendon is replaced by a homogenous, opaque, mucoid type of tissue.

What is a myxoid lipoma?

Myxoid adipocytic tumors encompass a broad heterogeneous group of benign and malignant adipocytic tumors, which are typically myxoid (e.g. myxoid liposarcoma, lipoblastoma and lipoblastoma-like tumor of the vulva) or may occasionally appear predominantly myxoid (e.g. pleomorphic liposarcoma, atypical lipomatous tumor.

What is a myxoid?

Myxoid is a word pathologists use to describe connective tissue that looks more blue or purple compared to normal connective tissue when examined under the microscope. The type of connective tissue that usually shows myxoid type change is called the stroma.

The pathogenesis of mucoid degeneration is unclear, but injury, ganglion cysts, and degenerative process have been implicated as the most likely etiologic factors in the production of this change.

What is a myxoid change?

Stromal myxoid changes can be defined as an amorphous stromal substance composed of an amphophilic or slightly basophilic vacuolated material found among the collagen fibers.

What causes myxoid liposarcoma?

Doctors aren’t sure exactly what causes liposarcoma. They do know these tumors form because of changes, called mutations, in the DNA of your fat cells.

Is myxoid normal?

Myxoid tissue consists of a gelatinous mucopolysaccharide matrix of sulfated and nonsulfated glycos- aminoglycans. It is not a normal tissue in adults and is actively secreted by the tumor cells in these lesions [1, 2].

Can a myxoid tumor be benign?

Myxoid soft tissue tumors are diversified group tumors of mesenchymal origin with a mucoid or myxoid extracellular matrix, which can be benign or malignant 1-3.

How rare is mucoid degeneration?

Epidemiology. ACL mucoid degeneration is present on ~10% (range 9-12%) of 3 T MRI examinations and 2% of 1.5 T MRI examinations 6.
