Summary
This study reports the first case of vaginal müllerianosis, a rare condition involving Müllerian glands in an unusual location. This finding expands the known sites where müllerianosis can occur.
Area of Science:
- Gynecologic Pathology
- Surgical Pathology
Background:
- Müllerianosis is characterized by heterotopic glands of Müllerian origin.
- Differential diagnosis includes vaginal adenosis and adenocarcinoma.
Observation:
- A 59-year-old woman presented with incidental vaginal müllerianosis in a rectosigmoidectomy specimen.
- Microscopic examination revealed endosalpingeal, endocervical, and endometrial glands in the vaginal cuff.
- Immunohistochemistry confirmed Müllerian epithelium and reactive stroma.
Findings:
- This is the first reported case of vaginal müllerianosis.
- The lesion exhibited a predominance of endosalpingeal epithelium.
- Immunoprofile included CK7, CK8/18, high molecular weight cytokeratin, ER-alpha, and AR.
Implications:
- The vagina should be recognized as a potential site for müllerianosis.
- Accurate differentiation from other vaginal lesions is crucial for patient management.
- Adds to the understanding of Müllerian duct remnant pathologies.

01:16Uterine Tubes
3.3K
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...

The vaginal canal is a tubular structure averaging about 10 cm in length that acts as the entryway to the female reproductive system and the passageway for menstrual flow and childbirth. The interior walls of the vagina exhibit concentric folds called rugae and are topped by an area known as the fornix, which connects with the protruding cervical portion of the uterus. This canal is comprised of an external fibrous layer, a muscular middle layer, and an inner lining with mucosal rugae, which...

The uterus, commonly called the womb, is a vital reproductive organ in females designed to provide a nurturing environment for the implantation and growth of an embryo. It is shaped like a hollow pear and positioned between the urinary bladder and the rectum. The uterus's structure allows it to support and protect a developing fetus throughout pregnancy.
The uterus is securely anchored within the pelvic cavity by paired broad ligaments on either side. It is further stabilized by three pairs...

02:07Oogenesis
71.2K
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...
