myxoma

Pronunciation: mik-so'ma

Definition: A benign neoplasm derived from connective tissue, consisting chiefly of polyhedral and stellate cells that are loosely embedded in a soft mucoid matrix, thereby resembling primitive mesenchymal tissue; occurs frequently intramuscularly (where it may be mistaken for a sarcoma), also in the jaw bones, and encysted in the skin (focal mucinosis and dorsal wrist ganglion).

[myxo- + G. -oma, tumor]
