Corpus luteum cyst

Introduction to corpus luteum cyst Pregnant women have a tendency to form corpus luteum cysts. Normal and gestational corpus luteum diameter is less than 2cm. If the corpus luteum is 2~3cm in diameter, it is called saccular corpus luteum. If the diameter is larger than 3cm, it is called corpus luteum cyst. When the cystic corpus luteum or corpus luteum cyst is degenerated, it transforms into a glass-like connective tissue, but still maintains the fluid in the cystic cavity and the cystic cavity. Its diameter is 2 to 3 cm, which is called cystic white body, and the diameter is larger than 3 cm. Cyst. basic knowledge The proportion of illness: 30% Susceptible people: good for women Mode of infection: non-infectious Complications: acute abdomen

Cause of corpus luteum cyst

(1) Causes of the disease

The onset factors of corpus luteum cysts are:

1 The blood vessels of the corpus luteum are supplied, and the lymphatic system is disordered;

2 The corpus luteum is excessively hemorrhagic during its angiogenic phase, especially in women with coagulopathy. The corpus luteum hemorrhage forms a corpus luteum hematoma. After the blood is absorbed, the clear liquid stays in the corpus luteum, which increases the diameter of the corpus luteum;

3 excessive secretion of pituitary gonadotropin, promote excessive development of the corpus luteum.

(two) pathogenesis

Gross shape

The corpus luteum cyst is a solitary cyst that occurs in the unilateral ovary. The surface is smooth and amber. The diameter is rarely more than 4cm, and it is rarely more than 8cm. However, the literature has reported 11cm, single-apartment, thin wall, translucent, and visible. The central cavity contains a pale yellow, reddish liquid or clot, and some or all of the walls are yellow, sometimes curled into a flower ring.

2. Organizational form

The lamellar surface is attached with a thin layer of mechanical tissue. The inner layer of the capsule wall is a layer of luteinized granule cells. The cytoplasm contains eosinophilic granules. The follicular cells are wedge-shaped and inserted into them. The cells are rich in capillaries, and finally the corpus luteum. The cyst is degenerated, leaving only 1 or 2 layers of cells.

Luteal cyst prevention

Regular physical examination to achieve early detection and early treatment. Special attention should be paid to the symptoms of sudden lower abdominal pain such as sudden menstrual cycle 20 to 27 days. Actively treat complications, prevent accidents, and follow up.

Luteal cyst complications Complications

The rupture of the cyst causes acute abdomen.

Symptoms of corpus luteum cysts Common symptoms Follicle enlargement of corpus luteum rupture cyst coagulopathy

Luteal cysts have no clinical significance in general, cysts can degenerate on their own, patients often complain of delayed menstruation, gynecological examination can increase the attachment of one side, Hallatt has reported 173 cases of corpus luteum rupture, which occurred in 78% of corpus luteum cysts Women with coagulopathy are prone to rupture of the corpus luteum cyst, and Lamb has encountered 4 ruptures of the corpus luteum cyst in a woman.

Examination of corpus luteum cyst

Examination of blood coagulation system, tumor marker examination.

Laparoscopy, histopathological examination.

Diagnosis and differentiation of corpus luteum cyst

diagnosis

Diagnosis can be made based on clinical manifestations, symptoms and related tests.

Differential diagnosis

Pregnant corpus luteum

The corpus luteum of pregnancy is less than 2cm in diameter, the granulosa cells of the capsule wall proliferate, the luteinization, the central non-cyst cavity, the wall of the capsule is all curled into a flower ring, and the urine HCG is positive.

Ectopic pregnancy

Acute abdomen caused by rupture of corpus luteum cyst is easily misdiagnosed as ectopic pregnancy. The former is negative for HCG, and the amount of bleeding is less than that of ectopic pregnancy, and there is no repeated bleeding.
