A cystic mass in the uterus often refers clinically to a cystic mass in the pelvis or in the adnexal region. The clinical management of such cystic masses is mainly based on the etiology. In the case of chocolate cysts on the ovaries, which often have a history of dysmenorrhea and can be associated with infertility, surgery is recommended as soon as possible, followed by Daphylline treatment, mainly to prevent recurrence. In the case of cystic masses in the fallopian tubes, the most common cause is chronic inflammation of the fallopian tubes, resulting in localized fluid accumulation in the fallopian tubes and causing cystic masses. Surgical treatment is recommended and should be given high priority because more than 90% of tubal cancers are due to chronic tubal inflammation.
