In general, mixed masses often suggest a cystic fluid with solid glandular tissue within the mass. Some of the mixed masses are the result of localized glandular hyperplasia with ischemic necrosis. Mixed masses are usually disorganized, with poorly defined borders and heterogeneous texture, and may be surrounded by abundant blood flow signals. Mixed masses may increase in size progressively within a short period of time and may even become cancerous. If a mixed mass is under close observation and painful symptoms appear, or if the size of the mass increases too rapidly, the patient may be advised to have the mixed mass surgically removed in order to prevent the mass from becoming cancerous. This can reduce the local pain symptoms and avoid more serious complications.
