Vaginal septum
Vaginal agenesis
Gartner duact cyst
Primary squamous Cell Carcinoma of vagina
Clear cell adenocarcinoma
Embryonal Rhabdomyosarcoma
51
Vaginal adenosis
and associated with
Focal persistence of columnar epithelium in the upper 1/3 of the vagina.
Associated with diethylstilbestrol (DES) exposure in utero(1/3 of the DES-daughters)
52
Vaginal septum
plus types plus how they are formed
Can be vertical or transvers.
Transverse result from faulty fusion or canalization of the urogenital sinus and müllerian ducts.
longitudinal vaginal septum forms when the distal ends of the müllerian ducts fail to fuse properly.
53
Vaginal agenesis
types
plus describe the types
Mullerian dysgenesis an isolated vaginal agenesis due to incomplete caudal development and fusion of the lower part of the mullerian ducts.
Mullerian agenesis(Mayer–Rokitansky–Kuster–Hauser syndrome) vaginal, uterus and fallopian tubes agenesis.
54
Gartner duact cyst
location anatomical and histological
Relatively common lesions found along the lateral walls of the vagina and are derived from wolffian (mesonephric) duct remnant.
They are 1- to 2-cm fluid-filled cysts that occur in the submucosal location.
55
histologically the cysts of gartner duct
simple cuboidal to low columnar
56
Primary squamous Cell Carcinoma of vagina
precursor lesion?
1% of female genital tract malignancy.
Vaginal intraepithelial neoplasia (VAIN) is precursor lesion.
High risk HPV is an important risk factor.
57
The most common malignant tumor to involve the vagina is ..........................................., followed by ...........................
carcinoma spreading from the cervix
primary squamous cell carcinoma of the vagina
58
metastasis of primary SCC of vagina
lower 2/3 vagina lesions metastasize to the inguinal nodes, whereas upper vagina lesions spread to regional iliac nodes.
59
Clear cell adenocarcinoma
plus
association
age
Malignant proliferation of glands with clear cytoplasm.
no glands in vagina
Rare, but feared, complication of DES-associated vaginal adenosis.
Mean age is 22 years with DES exposure and 55 years women with out DES esposure.
60
Embryonal Rhabdomyosarcoma
aka
age
= sarcoma botryoides
Malignant mesenchymal proliferation of immature skeletal muscle.
~ 90% of cases are diagnosed before 5 years of age.
This is a rare tumor of unknown etiology and pathogenesis.
61
Disease the uterine cervix
Transformation zone
Neoplastic disease of the cervix
62
Neoplastic disease of the cervix
include
Benign diseases include cervical polyps.
Premalignant and malignant diseases include CIN and invasive carcinoma.
63
Risk factor for precancerous and cancerous lesion of the cervix
HPV infection
Young age at first intercourse
Multiple sexual partners or a male partner with multiple sexual partners
Oral contraceptives
Cigarette smoking
High parity (multiparous)
Family history
Associated genital infections
Lack of circumcision in male sexual partner
64
Cervical intraepithelial neoplasia
types
course
type of dysplasia
CIN 1 2 3
Carcinoma in situ the invasive carcinoma
65
Invasive cervical carcinoma
and major type
3rd common female genital tract cancer in both incidence and mortality.
About 85% are Squamous cell carcinoma,10% Adenocarcinoma and 5% Adenosquamous , neuroendocrine and undifferentiated.
Occurs when CIN break the basement membrane and involve the cervical stroma.
66
Microinvasive tumor not extend beyond 5mm from nearest basement membrane.
Invasion of stroma and nesting of malignant cell in stroma there is also lymphocytic response.
Can be fungating , ulcerative or infiltrative
67
Clinical presentation
of invasive cervical carcinoma
Post coital vaginal bleeding
Leukorrhea
Dyspareunia
Pelvic pain
Sign and symptom of anemia
Sign and symptom of renal failure and dysuria
68
............................ is common cause of death and why
Obstructive renal failure
Direct extension to adjacent structures and to pelvic lymph nodes.
69
Screening
types for ICC
pap smear
visual inspection with acetic acid
visial inspection with Lugols iodine
70
Visual inspection with acetic acid(VIA)
If the cervical epithelium contains an abnormal load of cellular proteins, the acetic acid coagulates the proteins conferring an opaque and white aspect of the concerned area. A precancerous lesion has higher protein content when compared to normal epithelium. As a consequence it becomes white (acetowhite) and is considered to be “VIA positive”.
71
Visual inspection with lugol's iodine (VILI)
Lugol’s iodine, a compound that reacts with glycogen resulting in a brown or black coloration. Normal mature squamous epithelium contains glycogen. When in contact with Lugol’s iodine it becomes black, whereas precancerous lesions and cancer contain little or no glycogen thus turning yellow after Lugol application.
72
Vaccine
Gardasil = Quadrivalent ( HPV 6/11/16/18) virus like particle vaccine.
Best given before onset of sexual intercourse
Screening is still not stopped
