What is endometritis? What characterizes it on histology?

Inflammation of the endometrium (with plasma cells and lymphocytes)


What typically causes endometritis?

Associated with retained products of conception following delivery (vaginal/C-section)/miscarriage/abortion or foreign body such as IUD.


Why do retained products of conception cause endometritis?

Retained material in uterus promotes infection by bacterial flora from vagina or intestinal tract.


What is the treatment for endometritis?

Treatment: gentamicin + clindamycin with or without ampicillin


What is endometriosis?

Non-neoplastic endometrial glands/stroma outside of the endometrial cavity.


Where can endometriosis be found? Which sites are most common?

Can be found anywhere; most common sites are ovary, pelvis, and peritoneum


How does endometriosis appear in the ovary?

In the ovary, appears as an endometrioma (blood-filled "chocolate cyst")


What are 3 potential reasons for endometriosis?

Can be due to (1) retrograde flow, (2) metaplastic transformation of multipotent cells, or (3) transportation of endometrial tissue via the lymphatic system.


What 7 symptoms/signs characterize endometriosis?

Characterized by cyclic pelvic pain, bleeding, dysmenorrhea, dyspareunia, dyschezia (pain with defacation), infertility; NORMAL-SIZED uterus


What are 5 treatments for endometriosis?

Treatment: NSAIDs, OCPs, progestin, GnRH agonists, surgery


What characterizes cervical dysplasia/carcinoma in situ on histology?

Disordered epithelial growth; begins at basal layer of squamocolumnar junction (transition zone) and extends outward


What are the classifications of cervical dysplasia/carcinoma in situ? On what are these classifications based?

Classified as CIN 1, CIN 2, CIN 3 (severe dysplasia or carcinoma in situ), depending on extent of dysplasia


With what pathogenic strains is cervical dysplasia/carcinoma in situ associated? Why do these strains cause cancer?

Associated with HPV 16 and HPV 18, which product both the E6 gene product (inhibits p53 suppressor gene) and E7 gene product (inhibits RB suppressor gene).


What can happen with cervical dysplasia/carcinoma in situ if left untreated?

May progress slowly to invasive carcinoma if left untreated


How does cervical dysplasia/carcinoma in situ typically present? How is it diagnosed?

Typically asymptomatic (detected with Pap smear) or presents as abnormal vaginal bleeding (often postcoital)


What are the risk factors for cervical dysplasia/carcinoma in situ?

Risk factors: multiple sexual partners (#1), smoking, early sexual intercourse, HIV infection.


What kind of cells are often involved in invasive cervical carcinoma?

Often squamous cell carcinoma


Why is Pap smear such a useful test? What histological finding does it detect?

Pap smear can catch cervical dysplasia (koilocytes - wrinkled, "raisinoid" nuclei", some of which have clearing or a perinuclear halo) before it progresses to invasive carcinoma


What is a possible medical complication with regard to invasive cervical carcinoma progression, and what causes this?

Lateral invasion can block ureters, causing renal failure


What is adenomyosis? What causes it?

Extension of endometrial tissue (glandular) into the uterine myometrium; Caused by hyperplasia of the basalis layer of the endometrium


What symptoms/signs are associated with adenomyosis?

Dysmenorrhea, menorrhagia. Uniformly ENLARGED, SOFT, globular uterus


What is the uterus like in endometriosis? How does that compare to the uterus in adenomyosis?

Endometriosis - Normal-sized uterus; Adenomyosis - Enlarged, soft, globular uterus


What is the treatment for adenomyosis?

Treatment: Hysterectomy


What is an adenomyoma (polyp)? What might it contain?

Well-circumscribed collection of endometrial tissue within the uterine wall; May contain smooth muscle cells


Where can an adenomyoma extend, and how?

Can extend into the endometrial cavity in the form of a polyp


What are 2 types of endometrial proliferation?

(1) Endometrial hyperplasia (2) Endometrial carcinoma


What is endometrial hyperplasia, and what usually causes it?

Abnormal endometrial gland proliferation usually caused by excess estrogen stimulation


How does endometrial hyperplasia relate to endometrial carcinoma?

Increased risk for endometrial carcinoma


How does endometrial hyperplasia manifest clinically?

Clinically manifests as postmenopausal vaginal bleeding.


What are 4 risk factors of endometrial hyperplasia?

Risk factors include anovulatory cycles, hormone replacement therapy, polcystic ovarian syndrome, and granulosa cell tumor.
