Gastritis cystica profunda (GCP) is a rare
submucosal benign gastric lesion. Its etiology
is not clear, but the most important cause is
prior gastric surgery. GCP can be mistaken for
other gastric masses because it generally
cannot be diagnosed preoperatively. There is
no consensus on treatment of these lesions. Its
surgeries range from simple submucosal
excisions to total gastrectomies. As it is seen
so rarely, we present this case to raise
awareness of differential diagnoses of
stomach wall masses.
