[Asymptomatic gastric phytobezoar and anaemia due to iron deficiency revealing an autoimmune gastritis].
La Presse Médicale 2004 October 10
UNLABELLED: This observation recalls that gastric phytobezoar should lead to a search for an underlying disease and that a iron deficiency can be associated and hide macrocytosis related to a vitamin B12 deficiency.
CASE REPORT: A 19 year-old woman consulted for asthenia. Microcyte anaemia associated with iron deficiency was diagnosed. Upper digestive endoscopy revealed severe, totally asymptomatic phytobezoar. Biological investigations revealed a vitamin B12 deficiency, high serum gastrin level and strong positivity for gastric antiparietal anti-cell antibodies, suggestive of an autoimmune gastritis. Total immunoglobulin A deficiency was also noted.
DISCUSSION: Autoimmune gastritis is responsible for megaloblastic anaemia (vitamin B12 deficiency) but can also provoke microcytic (iron-deficiency) anaemia due to insufficient absorption of the latter and related to gastric achlorhydria. Phytobezoar might also be related to achlorhydria and/or gastroparesia associated with autoimmune gastritis. Hence, autoimmune gastritis should be searched for when confronted with unexplained gastric bezoar or iron-deficiency anaemia.
