| Esophageal Biopsy in a Patient
    with Alkaline Esophagitis* 
 Papillary Height is more than 90%, and Basal Zone Thickness is more than
          30% of total mucosal thickness. Inflammatory cells and cellular atypia
          are also
      evident. (H&E stain x 200) These findings are similar to pathology
      findings in chronic acid reflux.
 We have observed that pathology
    findings in patients with chronic bile reflux esophagitis are similar to
    acid reflux. Papilary
    Height > 1/2 and Basal
  Zone Thickness > 1/6 are considered as positive evidence for chronic Reflux
  Esophagitis (Arch Pathol 1975; 99:387-391). For more information on Alkaline Esophagitis, you can refer to the following
  study: Clinical Endoscopic and Pathologic Manifestations of Bile Reflux Esophagitis * Slide provided by Dr. Mazen Duwaji of Pathology
    Department at the Caritas
Norwood Hospital, Norwood, MA.
