What is Antoni A & Antoni B Pattern's are seen in and explain in detail?
Schwannoma *Distinctive histologic patterns seen within the peripheral nerve sheath tumor Schwan noma include the Antoni A and Antoni B regions oThese are the classic microscopic appearances of a schwannoma, which is benign. oNote the more cellular "Antoni A" pattern on the left with palisading nuclei surrounding pink areas (Verocay bodies). On the right is the "Antoni B" pattern with a looser stroma, fewer cells, and myxoid change. oNotice the whirly swirly pattern and how the cell nuclei are closely bunched together ... almost as if they're forming a fence (Verocay bodies). oSchwannomas are benign spindle cell tumors that occur along the edges of peripheral nerves.They can usually be removed without damaging the nerve itself.
