case_images: Examination of the lesional sections under light microscopy revealed these proliferations to be deep in the submucosa with tumor cells abutting the inner band of the muscularis propria (Fig. 1). Scattered intracytoplasmic spherical bodies surrounding by a clear halo (POBoM) were noted (Fig. 1). S-100 IHC staining demonstrated diffuse nuclear positive staining in the tumor cells (Fig. 1).
