Cysts associated with high levels of human chorionic gonadotropin and related to trophoblastic disease are called?

• A. Theca lutein cysts
• B. Corpus luteum cyst
• C. Serous cystadenoma
• D. Dermoid cyst

Answer: (A)

High hCG levels stimulate thecal interna cells to form cysts in the ovary, a process seen with trophoblastic disease such as molar pregnancy or choriocarcinoma. This results in theca lutein cysts, which are typically bilateral and often large and multilocular with thin walls. They arise specifically from the diffuse stimulation by hCG and tend to regress once the hCG level decreases or the trophoblastic condition is treated. In contrast, a corpus luteum cyst comes from the corpus luteum after ovulation and is usually unilateral and smaller, linked to very early pregnancy but not to markedly elevated hCG from trophoblastic disease. Serous cystadenoma and dermoid cyst are ovarian neoplasms unrelated to hCG stimulation, so their association with high hCG and trophoblastic disease isn’t a defining feature.
