Gestational choriocarcinoma is a form of gestational trophoblastic neoplasia, which is a type of gestational trophoblastic disease (GTD), that can occur during pregnancy. It is a rare disease where the trophoblast , a layer of cells surrounding the blastocyst , undergoes abnormal developments, leading to trophoblastic tumors .
Gestational trophoblastic disease (GTD) is a term used for a group of pregnancy-related tumours. [1] These tumours are rare, and they appear when cells in the womb start to proliferate uncontrollably. The cells that form gestational trophoblastic tumours are called trophoblasts and come from tissue that grows to form the placenta during pregnancy.
Choriocarcinoma is a malignant, trophoblastic [1] cancer, usually of the placenta. It is characterized by early hematogenous spread to the lungs. It belongs to the malignant end of the spectrum in gestational trophoblastic disease (GTD). It is also classified as a germ cell tumor and may arise in the testis or ovary.
The choriocarcinoma has 2 significant subtypes including gestational and non-gestational and they are differentiated by their different biological feature and prognosis. [4] Signs and symptoms of GTN will appear vary from person to person and depending upon the type of the disease.
A placental site trophoblastic tumor is a form of gestational trophoblastic disease, which is thought to arise from the intermediate trophoblast. [1] The tumor may secrete human placental lactogen, [2] and result in a false-positive pregnancy test. [3]
Theca lutein cyst is a type of bilateral functional ovarian cyst filled with clear, straw-colored fluid. These cysts result from exaggerated physiological stimulation (hyperreactio luteinalis) due to elevated levels of beta-human chorionic gonadotropin (beta-hCG) or hypersensitivity to beta-hCG.
A micrograph showing a choriocarcinoma spread to the lung [13] Choriocarcinomas are exceptionally rare which account for 2.1%-3.4% of all OGCTs. [ 14 ] Under gross examination, the syncytiotrophoblast cells are aligned in a plexiform arrangement with the mononucleated cytotrophoblast cells surrounding the foci of the hemorrhage. [ 1 ]
The 1997 International Germ Cell Consensus Classification [17] is a tool for estimating the risk of relapse after treatment of malignant germ-cell tumor. A small study of ovarian tumors in girls [18] reports a correlation between cystic and benign tumors, and conversely, solid and malignant tumors. Because the cystic extent of a tumor can be ...
