[Etiopathogenetic and clinical considerations of corpus luteum cysts].

The Authors report a case of hemoperitoneum after breaking of luteal cyst of corpus luteum and stress the main characteristics of this pathology. Ovarian cysts are frequently observed in the annexa; they are distinguished in folliculis cysts, luteal cysts, luteal cysts of corpus luteum. Their evolution, influenzed so both by endocrine factors so many from plogistic stimulation, pass through three essential moments: - obliteration for quick cicatrization of the stigma Graafian follicle; - hematic pouring and central softening; - increase of intracavitary fluid that stops with constitution of the fibrous tissue. In the second phase of the menstrual cycle, functional-anatomic changes occur that cause the formation of gravidic corpus luteum or menstrual corpus luteum. The luteal cysts of corpus luteum represent the result of the cystic evolution of the corpus luteum. These cysts are characterized by an intense endocrine activity and can frequently produce a surplus of steroids, particulary of progesterone. They can cause bleeding, often of slight entity but also severe that; these represent a frequent and dangerous complication, especially in women subjected to anticoagulant treatment with warfarin. This drug can determine a raise of intracystic pressure with consequent breaking of the capsule and hemoperitoneum for which is necessary emergency operation like in the case here described.
