The sections show a soft tissue spindle cell lesion cellular fibrillary areas (Antoni A) and pauci-cellular microcystic ~~area~~ (Antoni B). There are ~~paucinuclear~~ areas surrounded by clusters of nuclei (Verocay bodies). Thick hyaline blood vessels are present within the lesion. There is no apparent nuclear atypia. Mitotic activity is not readily apparent. No nerve is seen adjacent to the lesion. The lesion is partially encapsulated by a fibrous tissue. Focally, ink is seen on the lesional cells.
