MS usually lacks Verocay bodies, microcysts, a well-formed capsule, and thick-walled hyalinized blood vessels.
Antoni A areas are cellular with nuclear palisading and Verocay bodies where two rows of palisading nuclei are separated by pink fibrillary material.
Schwannomas were described by Verocay in 1908 as benign neoplasms of the peripheral nerves.
Schwannoma was first described by Verocay in 1908 and named as "neuroma," later in 1935 Stout suggested the name "neurilemmoma" because the tumor arises from nerve sheath and schwann cells (1).
GI schwannomas are capsulated tumors consisting of spindle cells with prominent lymphoid aggregations which are characterized by Antoni A and Antoni B areas, and the absence of typical Verocay bodies [33, 34].
Histopathological examination (Figure 3) showed the presence of characteristic hypocellular (Antoni A) areas with intermittent hypercellular (Antoni B) areas combined with the presence of Verocay bodies confirming the diagnosis of a benign schwannoma.
Microscopically (Figure 11), spindle-shaped cells in Antoni-A and Antoni-B arrangement interspersed with Verocay bodies are the characteristic features [2].
Neurofibromas do not display verocay bodies, Antoni A and B areas, nuclear palisading, or hyalinized thickening of vessels present in schwannomas.
Verocay [3] first described gastrointestinal schwannoma in 1910 [1, 10], with two histological growth patterns, namely, "Antoni A" and "Antoni B" [3].
The histopathological pattern formed by the palisading or alternating bands of epithelial cells and stroma similar to Verocay bodies is called "rippled pattern" (2).
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).
