case_images: Gross examination of the esophageal mass revealed a smooth, multilobulated, but well-circumscribed mass measuring 8.5 cm in greatest dimension (Figure 3).
case_images: Histology of the esophageal mass upon resection. Microscopic examination of the esophageal mass revealed palisading spindled cells with dense chromatin, rare mitoses and scattered atypia (H&E, x100). Immunohistochemistry revealed the tumor to be positive for the S100 protein (not shown), confirming nerve sheath origin.
