Gastric IgG4-Related Autoimmune Fibrosclerosing Pseudotumour : A Novel Location

الملخص EN

We describe the first reported case of an IgG4-related autoimmune fibrosclerosing pseudotumour located in the stomach of a 75-year old woman presenting with weight loss and vomiting.

A lesion was detected in the gastric body at endoscopy.

Subsequent characterisation by CT was suggestive of a gastrointestinal stromal tumour.

Following laparoscopic resection, the patient recovered uneventfully.

Histological examination of the resected specimen revealed an IgG4-related fibrosclerosing pseudotumour, a novel location for this histopathological entity.
