Histopathological Grading

A

grade tumors at a histopatho level

26
Q

Grade I

A

well-differentiated (low grade); tumor resembles normal (origin) tissue

27
Q

Grade IV

A

Does not resemble tissue it came from (poorly differentiated and high grade or anaplastic)-HARD to make a diagnosis

28
Q

A

64%

29

A

middle aged adults; F>M 2:3

30
Q

Oral lesions of Lichen Planus

A

white lace like dots on the insides of the cheeks and tongue, peeling

31
Q

Reticular Oral LP

A

Striations, papules, plaques

32
Q

Erosive Oral LP

A

Less common, symptomatic, peripheral striations and desquamative gingivitis–> Shiny red gums

33
Q

Diagnosis of LP

A

isolated solitary lesions worrisome, candidiasis, microscopic hard due to look alikes, use direct immunofluorescence (fibrinogen at BMZ)

34
Q

Treatment of LP
