Table 1. Summary of 5 pediatric cases of columnar metaplasia in the lower esophagus presenting with iron deficiency anemia.
Case | Age (yr) | Sex | Medical history | Hgb (g/dL) | Fecal occult blood test | Distal esophageal appearance | Distal esophageal histology |
---|---|---|---|---|---|---|---|
1 | 10 | Female | Severe neurologic impairment | 3.6 | Negative stool guaiac test | Ill-defined Z-line, nodularity, flame-shaped ulcerations proximal to the GEJ | GM, pseudogoblet cells |
2 | 15 | Male | Severe neurologic impairment | 7.0 | Positive stool guaiac test | Esophagitis, patulous LES, Z-line displaced proximally to the GEJ | GM |
3 | 8 | Male | EA, TEF | 8.7 | Negative fecal globin test | Z-line displaced proximally to the GEJ, patulous LES | GM, IM |
4 | 17 | Male | EA, TEF | 7.8 | Positive stool guaiac test | Z-line displaced proximally to the GEJ, patulous LES, edema | GM |
5 | 11 | Male | Severe neurologic impairment | 3.9 | Positive stool guaiac test | Erythema, superficial ulceration, clusters of bullous lesions | IM with ulceration |
EA – esophageal atresia; TEF – tracheoesophageal fistula; GEJ – gastroesophageal junction; LES – lower esophageal sphincter; GM – gastric metaplasia; IM – intestinal metaplasia. |
