Definition / general
  • Carcinoma characterized by the presence of malignant glandular epithelial cells within the squamous epithelium of the esophagus (paralleling WHO definition of Paget disease of nipple)
  • While Paget disease in the nipple has been reported without underlying malignancy, essentially all reported cases in the esophagus have underlying carcinoma
Epidemiology
  • May occur in 5% of esophageal resections for adenocarcinoma
  • Cases reported with underlying adenocarcinoma, mucous gland carcinoma and adenosquamous carcinoma (Am J Surg Pathol 2008;32:1068)
Clinical features
  • Occurs due to spread from underlying malignancy
  • In rare cases, may serve as a marker of underlying malignancy
Diagnosis
  • Endoscopic biopsy or resection
Prognostic factors
  • Prognosis related to underlying malignancy
Case reports
Microscopic (histologic) description
