Sections reveal partially ulcerated mucosal fragments infiltrated by an invasive moderately differentiated adenocarcinoma. The tumor is composed of crowded, irregular, and angulated glands exhibiting fused and back-to-back architecture with minimal intervening stroma. These neoplastic structures are set within a desmoplastic background and are lined by atypical epithelial cells demonstrating nuclear enlargement, hyperchromasia, pleomorphism, loss of polarity, and prominent nucleoli.
Dysphagia and heartburn. Endoscopy: multiple irregular nodules started at 25 cm below the dental arch and extends downwards, the largest is about 3 cm and irregular infiltrative circumferential tumor growth started at 30 cm from gastroesophageal junction, this growth extending down to the cardia with severe luminal narrowing. On background of previous barrettes esophagus.
Two biopsies were received:
1- Esophageal biopsy: soft tissue fragments collectively measured 0.5 cm, totally embedded.
2- Gastroesophageal junction biopsy: soft tissue fragments collectively measured 1 cm, totally embedded.
