Luteinized cyst

Introduction A comprehensive name for luteinized cysts, including corpus luteum cysts, white body cysts, and follicular flavin cysts. Follicular flavin cysts are often associated with hydatidiform moles and choriocarcinoma. Early pregnancy can often be combined with corpus luteum cysts, generally no symptoms, more often found in routine gynecological examinations. Do not misdiagnose as an ovarian cystadenoma and remove it. During non-pregnancy, endocrine activity due to corpus luteum cysts can cause delayed menstrual cycles, followed by persistent or irregular uterine bleeding. The uterine lining of the endometrium is sometimes decidual. Sometimes the affected lower abdomen is slightly painful.

Cause

(1) corpus luteum cysts: the most common, varying in size, most do not exceed 2-3 cm in diameter, but even up to 10 cm. Often occurs on one side.

(2) White body cysts: Most of them evolved from corpus luteum cysts, so they are all small, and the wall of the cystic wall is a transparent white body. Microscopic examination: The wall of the capsule is a dense fibrous tissue.

(3) Follicular flavin cyst: often bilateral, polycystic cyst, so the surface is lobulated, the capsule wall is thin, containing a clear or amber liquid. The difference in size is extremely significant, the small one is only slightly larger than the normal ovary, and the large one can fill the entire pelvic cavity, generally 8-10 cm in diameter, and the largest one can reach 20-25 cm.

Early pregnancy can often be combined with corpus luteum cysts, generally no symptoms, more often found in routine gynecological examinations. Do not misdiagnose as an ovarian cystadenoma and remove it. During non-pregnancy, endocrine activity due to corpus luteum cysts can cause delayed menstrual cycles, followed by persistent or irregular uterine bleeding. The uterine lining of the endometrium is sometimes decidual. Sometimes the affected lower abdomen is slightly painful. Occasionally, flavin cysts may be twisted or ruptured, and rupture may cause intra-pelvic hemorrhage. Generally, the amount of bleeding is small. White body cysts have no hormonal function and generally do not cause symptoms and can disappear by themselves. The follicular luteinized cyst and the multi-energy of the hydatidiform mole self-resolved. After a normal pregnancy, the invasive hydatidiform mole or choriocarcinoma naturally disappears after healing.

Differential diagnosis

Flavin cysts can be formed in the following three cases:

(1) Luteal cyst: The corpus luteum is imbalanced by pituitary gonadotropin, especially in the function of gestational corpus luteum. If the cavity enlarges more than 2 cm in diameter, it is a corpus luteum cyst.

(2) White body cysts: mostly caused by the evolution of corpus luteum cysts and cystic corpus luteum. It is also possible that a cyst is formed due to a certain factor when the normal corpus luteum degenerates into a white body.

(3) Follicular flavin cyst: mostly occurs in hydatidiform mole, invasive hydatidiform mole, and choriocarcinoma. Hydatidiform moles with ovarian flavin cysts account for about 50-60%, and the actual incidence may be higher than this number. Occasionally occurs during normal pregnancy and twins.
