A benign tumor composed of mucinous connective tissue.



a benign tumor made up of connective tissue and containing a large amount of mucus. Myxomas arise from residues of embryonic (mucous) connective tissue or from mucous transformation of fibromas or lipomas. They may be found in all organs, particularly in the extremities, subcutaneous tissue, and mesentery. Myxomas are treated by surgery; they may recur if not completely excised.
