" Hello I am a cheater cock..... Oh Plz I am not Malignant!!" My take on GCT

Benign tumor
Dorsum of tongue most common site of occurrence
appears as nodule
H/P mimics SCC with pseudoepitheliomatous hyperplasia with syncytium of granular cells
Oh no.... u should still search for my parents !!!! origin unknown------- Muscle outdated, neural- under study

local excision would suffice, uncommon recurrence
very rarely malignant transformation

Backdrop:

Also known as Abrikossoff’s tumour

What it all about??!!!

So here i wish to have a backup of my knowledge which i would gain in the field of OMFP from now on. so i am gonna blog my brain !!!;-) ;-) :-) gonna get started with a nice case !!!!!!!!!
