Flashcards in Anal Path I Deck (25):
1

dentate line

pectinate

important in anal issues

above - glandular
below - squamous

also transitional zone

2

external hemorrhoids

below dentate line
-painful

3

internal hemorrhoids

above dentate line

can prolapse and bleed

4

anal fissure

posterior wall

impacted fecal material
-painful

5

perianal fistula

abnormal connection between epithelialized surface of anal canal and abscess of skin

primary - obstruction

secondary - iatrogenic, diverticulitis, IBD, infection, cancer

6

seton drain

surgical tx of perianal fistula

facilitates healing of fistula and draining

7

pain with bowel movement and stained underwear

perianal fistula

8

opening of anal fistula

can tell location of abscess

9

superior rectal abscess

can be palpated on DRE

-pain worse with bowel movement
-fever/sepsis

10

anal fistulas

are classified - parks

11

crohn disease

can see anal fistula and abscesses

12

anal condyloma

papilliform appearance

contrast to SCC - has smooth and pearly appearance with hemorrhage and necrosis

low risk HPV association

13

koilocytosis

seen with anal condylomas

14

HPV

induces dysplasia of squamous epithelium

virus gets to basal cells - become premalignant - large darker nuclei to surface

15

high grade HPV

large dark nuclei to surface

16

low grad HPV

koilocytes - anal condyloma

17

atypical anal lesion

biopsy needed**

18

CIN

cervical intraepithelial neoplasm

19

AIN

anal intraepithelial neoplasia

low grade

20

SCC of anus

keratin pearly

21

basaloid carcinoma

in transition zone
-rare tumor

-like SCC - same tx

no keratin
-just blue basaloid cells

22

HPV 16 and 18

SCC of anus

23

above dentate lymph

perirectal and paravertebral nodes

24

below dentate lymph

superficial inguinal and femoral nodes

25

prognosis anal ca

tumor diameter and nodal involvement
