Case Reports in Pathology
|September 15, 2025
Summary
This case report details an uncommon placental site nodule (PSN) discovered in a fallopian tube during cesarean-assisted tubal sterilization. Recognizing these benign lesions in extrauterine locations is crucial for accurate diagnosis.
Area of Science:
- Reproductive Pathology
- Gynecologic Oncology
- Trophoblastic Disease Research
Background:
- Placental site nodules (PSNs) are rare lesions originating from prior implantation sites.
- PSNs are typically identified in uterine specimens, with extrauterine occurrences being exceptionally uncommon.
- This report focuses on an incidental PSN found within a fallopian tube.

01:16Uterine Tubes
2.1K
The uterine or fallopian tubes function as the conduit through which oocytes travel from the ovaries to the uterus. Each fallopian tube measures approximately 10 to 13 cm long and is anatomically divided into the infundibulum, ampulla, isthmus, and interstitial part (or intramural segment). The infundibulum is characterized by its funnel shape and features extensions called fimbriae which reach towards the peritoneal cavity. These fimbriae play a critical role during ovulation as they extend...

01:24Gonadal and Placental Hormones
2.8K
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair...

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...
