This is basically a question of terminology. (FA2020 p219)
Invasive means it has penetrated the basement membrane but "microinvasive" would assume it has not invaded surrounding tissues as it has not metastasized.
dhkahatam i crazy here? This questions seems odd to me. Because full thickness of the epithelium had to have been covered by neoplastic cells first right? idk maybe i got confused by the wording what "lead to this diagnosis"+1
j44nwhat they're talking about with that one is a carcinoma insitu-> IE its neoplastic but it has yet to invade+1
ali_hassanso basically the full thickness of epithelium has been occupied and it's gone slightly beyond into the-basement membrane tissue, but not the actual membrane tissue (hence "micro"invasion)+2
microinvasion as a lesion that invaded below the basement membrane to a depth of 3 mm or less, with no evidence of invasion of the lymphovascular space.
