Clinically the patients may remain asymptomatic or symptoms can be non- specific, which include abdominal mass, pain, nausea and emesis. We report a four year old male child who presented with intermittent pain in abdomen. The child was evaluated for the same by radiology which suggested a duplication cyst in epigastric region. The child underwent excision for the same following which histopathology confirmed the diagnosis of gastric duplication cyst (Gastric mucosal cyst). Although a benign entity, it has risk of complications such as obstruction, torsion, perforation, haemorrhage, and malignancy. Abstract 1 Associate Professor, Department of Pathology, Dr. D.Y.

Duplication cyst is capable of occurring anywhere within the gastrointestinal tract. 1 GDCs represent 4% of all alimentary tract duplications, and approximately 67% manifest within the first year of life. 2 It is most frequently diagnosed in young children presenting with abdominal pain, vomiting or as asymptomatic abdominal mass. We report a rare case of four years male child with pain abdomen diagnosed as gastric duplication cyst (Gastric mucosal cyst). Case Report Four years, male child, presented with intermittent pain abdomen and intermittent fever for last six months. There was no history of vomiting, nausea, constipation, loose stool, jaundice, loss of weight. Past medical history was not significant. Physical examination revealed mild epigastric fullnesses with no guarding or rigidity. Hence the child was subjected to further radiological evaluation. Ultrasonography (USG) abdomen and pelvis revealed a small anechoic lesion in right epigastric region in sub hepatic area close to gall bladder fossa suggestive of duplication cyst (Figure 1).
