Study Notes
Microscopic Anatomy and Neoplasia in Female Genital Tract
- Vulva and Vagina: Majora skin with hair follicles and sweat glands, minora and vagina with mucosa, and the role of oestrogen in maturation of squamous epithelial cells.
- Cervix: Ectocervix with stratified squamous epithelium, endocervix with columnar cells, and the transformation zone during puberty.
- Metaplasia: Adaptive change of endocervical columnar cells to squamous epithelium in response to the vaginal environment.
- Body of the Uterus: Myometrium composed of smooth muscle, vasculature, and nerves, and the endometrium with proliferative and secretory phases.
- Neoplasia: Abnormal, uncoordinated cell growth in the female genital tract and the nomenclature based on behavior and histogenesis.
- Benign Neoplasms: Localized, slow-growing leiomyoma of the myometrium and their consequences, including pressure on adjacent tissue.
- Malignant Neoplasms: Characteristics such as invasion into surrounding tissues, metastasis, and variable resemblance to parent tissue.
- Consequences of Neoplasms: Destruction of adjacent tissue, metastasis, blood loss, and obstruction of hollow viscera.
- Histogenesis and Terminology: Classification of neoplasms based on histological appearance and the nomenclature of malignant epithelial and stromal tumors.
- Endometriosis: Presence of endometrium-like tissue outside the uterus, symptoms, and low risk of neoplasia.
Understanding the Vaginal Epithelium and Cervical Transformation Zone
- Vaginal epithelium lays down glycogen in response to estrogen, which is used as a substrate for anaerobic organisms, particularly lactobacilli.
- Lactobacilli fermentation of glycogen keeps the vaginal environment acidic, beneficial for the microbiome and infection avoidance.
- The cervix extends into the vagina and contains the active cervix, cervix, and the formation of the cervical transformation zone.
- The cervix is covered by stratified squamous epithelium, influenced by estrogen during development.
- The endocervix is lined by a single layer of columnar mucin-producing cells.
- The cervical stroma separates the columnar cells from the basement membrane, with the cells containing oval nuclei and frothy cytoplasm.
- The endocervix has ramification spaces lined by columnar epithelial cells, increasing the volume of mucus production.
- The cervix has an area covered by columnar epithelium and another by stratified squamous epithelium, meeting at the squamocolumnar junction.
- During puberty, the cervix's shape changes, with the distal end flaring open, exposing more of the endocervix to the vaginal environment.
- This exposure occurs due to the flaring open of the cervix's distal end, leading to more of the endocervix being exposed to the vaginal environment.
- The exposed area of the cervix is known as the transformation zone.
- The transformation zone is a critical area in cervical health and disease management.
