From: Keratin expression in schwannoma; a study of 115 retroperitoneal and 22 peripheral schwannomas
In total, 62% of the retroperitoneal schwannomas (and none of the peripheral schwannomas) were positive for AE1/AE3 (1–4+); with a similar distribution to GFAP, keratin cocktail concentrated adjacent to the capsule, myxoid or degenerative areas, and in a perivascular distribution (a, b).
