Gynecology . s. The vaginal wall was removed during the operation and is seen in thedrawing surrounding the lower myoma. Myxomatous degeneration, so-called, is a misleading term.

A better term for this change would be myxoma-toid degeneration. Cystic degeneration in some cases represents a still more marked serousinfiltration by which the fluid exudate becomes confined in certain areas, soas to create cavities in the tissue of the tumor. Enormous cysts may form bythe coalescing of smaller cysts. Cystic formation in uterine fibroids also results from other causes thanpassive congestion. Changes in the blood- and lymph-vessels may producecystic tumors of the angiomatous and lymphangiectatic type. In some of thelarge cystic myomata there is doubtless an abnormal secretory action on the.

Cysts may also result from a local necrosis of the myoma with lique-faction of the tissues. This is sometimes seen in fibroids that have been treatedby radiation. In some cases the cysts originate in the glandular elements of anadenomyoma. Red degeneration relates to a form of degeneration characterized by a brightred color of the tissue. There are two types of red degeneration, the thromboticand the angiomatous. The thrombotic type is especially common in tumorscomplicating pregnancy. These tumors degenerate rapidly and easily becomeinfected. They usually grow rapidly and may be very painful and exquisitely NEW GROWTHS 265 tender to the touch. They are apt to be attended with fever and other consti-tutional symptoms. The angiomatous tumors show free blood on the cut surface from numerousthin-walled blood-vessels. They are clinically less i
