Carcinoid tumor is a rare neuroendocrine neoplasm, and primary ovarian carcinoid is extremely uncommon. Ovarian carcinoid during pregnancy is exceptionally rare and diagnostically challenging. We report the case of a 30-year-old primigravida who underwent cesarean section for fetal distress, during which a left ovarian cyst was incidentally found. Pathological examination revealed a mature cystic teratoma with carcinoid (trabecular type). The patient underwent laparoscopic adnexectomy six weeks after cesarean delivery with curative intent. Final pathological staging was FIGO IA. Maternal and neonatal outcomes were favorable, with no evidence of recurrence during 18 months of follow-up. This case highlights the clinicopathological features, diagnostic challenges, management strategies, and prognosis of ovarian carcinoid during pregnancy and aims to enhance clinical awareness.

Ovarian Cycle01:27

Ovarian Cycle

The menstrual cycle includes a critical component known as the ovarian cycle, which undergoes two main phases each month—the follicular phase and the luteal phase. The follicular phase is variable and averaging around 14 days. Ovulation, triggered by a surge in luteinizing hormone (LH), marks the transition between the two phases. The second phase, the luteal phase, is relatively consistent, lasting approximately 14 days, and is marked by the activity of the corpus luteum. While a cycle length...
Oogenesis02:07

Oogenesis

In human women, oogenesis produces one mature egg cell or ovum for every precursor cell that enters meiosis. This process differs in two unique ways from the equivalent procedure of spermatogenesis in males. First, meiotic divisions during oogenesis are asymmetric, meaning that a large oocyte (containing most of the cytoplasm) and minor polar body are produced as a result of meiosis I, and again following meiosis II. Since only oocytes will go on to form embryos if fertilized, this unequal...
