case_images: In addition, there were several atypical glandular cells with large hyperchromatic nuclei and thick cytoplasm [Figure 1a]. Cellular strips with nuclear pseudostratification, reminiscent of short "bird tail like" arrangements were also seen [Figure 1b]. Some tumor cells were spindle shaped similar to a high-grade anal intraepithelial neoplasia or squamous cell carcinoma [Figure 1c]. Histologic examination of the resected material demonstrated invasion of the muscularis propria by neoplastic glands [Figure 1d].
