what are cervix problems?
endocervical polyp
SIL
Adenocarcinoma in situ
Cervical carcinoma
PAP smear
what are 2 types of cervix cells we have ?
Ecto cervix —> STRATIFIED SQUAMOUS EPITHELIUM —> if it would become cancer it would be squamous cell
Endocervix =Inner cervix = towards the utereus –> Mucus secreting columnar epithelium –> if it becomes cancer it would be adenocarcinoma
what is transformation zone?
aka squamocolumnar junction
the point where the 2 types of cells of the cervix meet
its very active and targeted by HPV
what is an endocervical polyp?
a polyp arising from the endocervical part of cervix
what is the clinical presentation of endocervical polyp?
40-60 years old
Abnormal vagina bleeding
what are the grossly features of endocervical polyp?
Polypoid mass with smooth surface
what are the microscopic features of polyp?
generally all polyps are projections lined by epithelium with a fibrovascular core
so here its endo so lined columnar epithelium secreting mucus –> ENDOCERVICAL GLANDS
with fibrous stroma and thick walled vessels
Note : the lining could be either squamous or columnar but the endocervical glands are present always
whats the difference between polyp and papillary?
polpy has smooth surface
papillary has projection
what is condyloma acuminatum?
Condyloma = mass
Acuminatum = pointed
its aka Genital wart
Genital cuz its in the genitalia
Wart = another name for papillae but for viral
it makes papillae
what causes Condyloma acuminatum ? genital wart
HPV TYPE 6 , 11
HPV affect human
and it attacks epithelial tissue especially sqamous and penetrate until basal cells then it lives there and lead to formation of papillae
type 6 and 11 are low risk so they have low chance of cancer cuz they dont reach DNA
SPREAD BY SKIN TO SKIN CONTANCT
what are the grossly features of condyloma acuminatum ?
Exophytic papillary lesion
what are the microscopic features of condyloma acuminatum ?
Papillary ( fingerlike ) lesion
Hyperkeratosis in case the virus affected a cell with keratin
Acanthosis –> increase epidermis thicking
Koilocytic changes :
viral effect on the cell , the nucleus shrink and hyperchromatic creating PERINUCLEAR HALOS ( chromophobe RCC )
what is squamous intraepithelial lesion? SIL?
aka Cervical intra epithelial neoplasia (CIN )
its a dysplasia = malignant transformation of cells = divide uncontrollably
notice the name squamous = affect squamous only
so it only affects the ectocervical region and not endo cuz endo is columnar and not squamous
what are 2 types of squamous intra-epithelial lesion ? or CIN?
Low grade SIL –> mild dysplasia
High grade SIL
what causes high grade SIL?
HPV = 16 and 18
6 and 11 were low risk so only polyps
here 16 and 18 are high risks = dysplasia
what are the grossly features of SIL/CIN?
normally dysplasia is something we only see under microscope but here we can see it :
using colposcopy appears as :
Discolored raised plaques
how do we confirm that the Plaques are SIL?
1st:
Apply acetic acid :
IF normal = retain pink color
IF abnormal = WHITE MOSAIC OR COBBLESTONE
2nd step :
Apply Lugol iodine :
If normal = Squamous epithelium become brown
If abnormal = Bright yellow non iodine uptake
what are the microscopic features of Low grade SIL? or CIN1?
Nuclear poleomorphism and hyperchromasia in lower 1/3 of epithelium
what are the microscopic features of HGSIL?
Nuclear pleomorphism and hyperchromasia in lower 2/3 –> CIN2
or
Nuclear pleomorphism and hyperchromasia in ENTIRE thickness = BECOMES CARCINOMA IN SITU -> CIN3
what is an important marker for High grade SIL?
P16 immunochimstery
Strong and diffuse nuclear and cytoplasmic positivity in the full thickness = forms block
ITS IMPO CUZ IT REACTES STRONGLY WITH CELLS IN CASES OF HIGH RISK HPV
if you see P16 = HIGH GRADE SIL = high risk HPV
what is the treatment of SIL/CIN?
Low grade = Most lesions regress but keep following up
High grade = Loop electrosurgical Excision procedures (LEEP ), conization , laser, cryosrugery, thermal ablation –> regardless of the way you need to remove it
what is Adenocarcinoma insitu?
Similar to SIL but this time its endocervix with the columnar gland cells ( dysplasia but in columnar gland cells )
its aka Cervical glandular intra-epithelial neoplasia
It can become invasive if not treated
what is the clinical presentation of ADC in situ?/ CGIN?
Asymptomatic
Cant even be seen grossly like SIL
what are the microscopic features of ADC in situ or CGIN?
Repalcement of endocervical epithelium on surface and glands by :
ABNORMAL ATYPICAL EPITHELIUM
