Histopathological evaluation of the specimen revealed a circumscribed mass comprised of spindle-shaped cells arranged in Antoni A configuration surrounding eosinophilic structures looked like verocay bodies (Figure 2a).
2) La region Antoni A es una zona hipercelular cuyas celulas son fusiformes con nucleos que se disponen en empalizada formando filas paralelas y dando origen a los cuerpos de Verocay.
Histopathologically gastrointestinal schwannoma are spindle shaped cells with a prominent lymphocytic cuff and are characterized by the absence of typical Verocay bodies, Antoni A and Antoni B areas10.
Scattered prominent Verocay bodies were also identified (Fig 5).
Gastrointestinal schwannomas often lack the prototypical nuclear palisading, Verocay bodies, and Antoni A and B areas seen in their soft tissue counterparts and often appear uniformly cellular.
Microcalcifications with ossification and Verocay body formations were identified.
Neurilemmoma was first described by Verocay in 1910.
Antoni A areas were composed of spindle-shaped cells forming Verocay bodies.
The first Antoni A pattern showed closely arranged bundles of schwann cells with spindle-shaped nuclei which were aligned in parallel rows, which formed a typical palisading pattern around acellular, amorphous, eosinophilic masses, which represented the verocay bodies.
The histopathological report showed an arrangement of spindle cells in a storiform pattern with Verocay bodies interspersed with myxomatous areas.
2) Histologically they are described as Antoni type A (highly cellular, tightly compact spindle-shaped cells which pallisade and produce Verocay bodies) and Antoni type B (less cellular and more randomly arranged spindle cells in a loose, myxomatous stroma).
Schwannomas are peripheral nerve sheath tumors that, in contrast to neuromas, have thick collagenous capsules, true Verocay bodies, and hypocellular or myxoid (Antoni B) stroma (3).
