<prompt> Schwannoma, the marked area representsMyxoid tissueAntony A pattern - Verocay bodiesAntony B pattern -Verucoy bodiesAntony C pattern  <response>: Schwannoma Well circumscribed, encapsulated masses that are attached to a nerve but can be separated from it Whereas neurofibromas are unencapsulated, an ill circumscribed mass that presents within the nerve and expanding them, hence the tumor cannot be separated from the nerveMicroscopic findings :Two patterns - Antoni A and Antoni B patterns Antoni A - Cellular with spindle cells showing nuclear palisades. There is an alternate array of nuclear palisades and nuclear-free zones were together called Verocay bodiesAntoni B - Less densely cellular and consists of a loose meshwork of cells, microcysts, and myxoid stroma.Ref: Robbins 8e p1340
