Roveda- Benign and Malignant Disorders of female GU tract Flashcards
Reactive inflammation of vulva in response to an exogenous stimulus
Vulvitis
HSV-2, N. gonorrhoeae, Treponema pallidum, and C. albicans, and M. contagiosum can cause what
vulvitis
causative agent of a genital ulcerative lesion in the vulva
Herpes simplex

Treponema pallidum
fungus that causes a yeast infection in vulva
Candida albicans
a cutaneous or mucosal lesion caused by poxvirus. (present in eyes and in vulva)
Molluscum contagiosum
associated with condyloma acuminatum and vulvar intraepithelial neoplasia.
HPV
stiffened labial folds with smooth white plaques-leukoplakia
postmenopausal
Lichenoid sclerosis
epithelial THINNING
hyperkeratosis
classic for…
Lichen Sclerosis
with ______ there is an increased risk of developing SCC in vulva
Lichen Sclerosis
if you see leukoplakia in the mouth what are you trying to first exclude
SCC, then lichen lesions
area of leukoplakia
epithelial THICKENING
Lichen simplex chronicus
warty lesions
Condyloma
squamous cells which become infected with HPV have nuclear wrinkling with cleared cytoplasm
koilocytes
usually do not progress to invasive cancer; HPV subtypes 6 and 11 cause this
Condyloma acuminatum
“stuck on pieces of cauliflower”
Condyloma acuminatum
Marked thickening of epidermis; hyperkeratosis; turnover of cells
Condyloma
90% of vulvar carcinomas are _____
SCC
2 distinct forms of vulvar carcinoma (squamous cell carcinoma):
HPV subtypes 16 and 18
preceded by lichen sclerosis
Young age at first intercourse
Intercourse with multiple partners
Intercourse with a male partner who has had multiple partners
risk factors for HPV related diseases in vulva and cervix
HPV related vulvar carcinoma
lesion will look grossly like ______ due to the hyperkeratosis overlying the areas of squamous dysplasia
leukoplakia
normal on L side
vulva
vulvar intraepithelial neoplasia
vulva
vulvar squamous cell carcinoma
pretty good prognosis of vulvar _____ if you catch it while the lesion is small
vulvar carcinoma
Remember in Paget’s disease of the breast (which is referred to as mammary Paget’s), virtually 100% of patients have an underlying ______ ductal carcinoma of the breast.
invasive
About 30% of patients with perianal Paget’s have an underlying _____ carcinoma
invasive
Intraepithelial proliferation of malignant epithelial cells that can occur in the skin of the vulva (can also occur in the perianal area); most not associated with an underlying tumor
Extramammary Paget Disease
On gross image: red scaly crusted plaque
extramammary paget disease
red scaly crusted plaque
“area oozing, and see red scaly area, and frequently pruritic”
Extramammary Paget’s disease
disease- large pale cells with intracytoplasmic mucin which infiltrate the epidermis of the vulva
Extramammary Paget’s Disease
most people with ______disease do not have underlying invasive carcinoma
Extramammary Paget’s disease
pigmented lesion on labia
vulvar melanoma
what 2 things could this be if in vulva
Paget’s disease; vulvar melanoma
S-100 and HMB45 to stain for _____
melanoma
mucin stain to rule out_____
Paget’s
inflammatory, transient condition associated with discharge which is known as leukorrhea
vaginitis
causes curdy white discharge from vagina
Candida albicans
watery grey green frothy discharge – the cervix is grossly described as strawberry cervix
Trichomonas Vaginalis
Normal _____ of vagina can become pathogenic in the setting of diabetes, antibiotic therapy, pregnancy, or immunodeficiency
flora
uncommon in patients, but is the most common cancer of vagina occurring in patients older than 60
SCC
Usually preceded by vaginal intraepithelial neoplasia which is associated with HPV infection
SCC of vagina
The most significant risk factor for squamous cell carcinoma of the vagina is a previously diagnosed squamous cell carcinoma of the _____ or ______
cervix or vulva
1970s cluster of young women whose mothers took diethylstilbestrol to prevent threatened abortion got _____ adenocarcinoma of vagina
clear cell adenocarcinoma of vagina
Embryonal rhabdomyosarcoma—rare form of vaginal cancer that manifests as polypoid masses of tissue protruding from vaginal os (in young patients)
Sarcoma botryoides
mesenchymal sarcoma of vagina
sarcoma botryoides
Small round blue cell neoplasm with skeletal muscle differentiation
Sarcoma Botryoides
may express muscle specific marker desmin
Sarcoma Botryoides
results in epithelial metaplasia in the endocervical transformation zone: stratified squamous of ecto and merges into glandular of endo
cervicitis
the spread of this infection requires direct contact with the mucosa of an infected individual; infects cervix
Neisseria gonorrhoeae
most common bacterial cause of STD in the US, dx is made not thru culture but rather by nucleic acid amplification on voided urine; infects the cervix
Chlamydia
patients infected with ____ can get reactive arthritis known as Reiter’s syndrome
Chlamydia
will see Cowdry type A viral inclusions on pap smear
herpes
L: strawberry cervix
middle: grey green discharge
R: pap smear of organism
Trichomonas
____has a tropism for immature squamous cells of the transformation zone, basal layer at the squamocolumnar junction
HPV
where the ectocervical squamous mucosa meets the endocervical glandular mucosa
cervical transformation zone
if HPV infection persists, then can progress to SIL and CIN which are
squamous intraepithelial lesion
cervical intraepithelial neoplasia
Early age at first intercourse
Multiple sexual partners
Male partner with multiple previous sexual partners
Persistent infection with high risk strains of HPV
risk factors for squamous intraepithelial lesion
high risk strains of HPV for squamous intraepithelial lesions and cervical cancer
types 16 and 18
high risk subtypes of HPV______ into the host genome
integrate
low risk subtypes of HPV ___ and ___ are associated with condylomata and DO NOT integrate into the host genome
6 and 11
Persistent and long term infection of _____is what increases risk for developing SIL and cervical cancer
