PATH - Cervical Cancers Flashcards
Choriocarcinoma
Rare
can develop during or after pregnancy in mother or baby.
Malignancy of trophoblastic tissue (cytotrophoblasts, syncytiotrophoblasts)
*no chorionic villi present
Presents with abnormal INC β-hCG, shortness of breath, hemoptysis
Hematogenous spread to lungs.
INC frequency of bilateral/
multiple theca-lutein cysts
Squamous cell
carcinoma (SCC) of vagina
Usually 2° to cervical SCC
1° vaginal carcinoma rare
Clear cell adenocarcinoma of vagina
Affects women who had exposure to *DES in utero
Sarcoma botryoides (embryonal rhabdomyosarcoma variant)
Affects girls
Dysplasia and carcinoma in situ of cervix
Disordered epithelial growth
begins at basal layer of squamocolumnar junction (transformation zone) and extends outward
Associated with:
HPV 16 - E6 gene product (inhibits p53 suppressor gene)
HPV 18 - E7 gene product (inhibits RB suppressor gene)
Typically asymptomatic or presents as *abnormal vaginal bleeding (often *postcoital)
RISK
multiple sexual partners (#1), smoking, starting sexual intercourse at young age, HIV
infection.
Invasive carcinoma of cervix
Often *squamous cell carcinoma.
Pap smear can catch cervical dysplasia (koilocytes) before it progresses to invasive carcinoma.
Diagnose via colposcopy and biopsy.
Lateral invasion can block
ureters–>renal failure
