From: Pathologic assessment of gastrointestinal tract and pancreatic carcinoma after neoadjuvant therapy
(a) A patient who underwent an esophagectomy following neoadjuvant therapy for squamous cell carcinoma had extensive keratinous material associated with calcifications within the submucosa (× 100). This should not be interpreted as viable carcinoma. (b) A patient who underwent an esophagectomy following neoadjuvant therapy had extensive residual carcinoma following neoadjuvant therapy (CAP tumor regression grade score 3) with areas demonstrating neuroendocrine differentiation (left half of image) and areas with mucinous differentiation (right half of image) (× 100).
