Rare Occurrence of Mix Stromal Tumours: A Case Report Of Gastrointestinal and Extra-Intestinal Stromal Tumour on the Jejunum And Omentum of a Nine Year Old Girl From Adamawa State, Nigeria

Abstract

Background: Stromal tumors of the jejunum (GIST) and omentum (EGIST) are uncommon and dearth of information still exists on their occurrence concurrently.
Case details: Here, we report a nine year old girl that presented with tender abdominal mass measuring 14 x 8 cm associated with features of gastric outlet obstruction and hyponatremia of 115mmol/L. A diagnosis of hyponatremia in a child with gastric outlet obstruction secondary to intraabdominal mass was made for which exploratory laparotomy was carried out. Histology of the tumour revealed stromal spindle epithelioid as well as myxoid cells. Complete resection of the tumour and correction for hyponatremia was done in addition to antibiotics therapy with remarkable improvement.
Conclusion: Index case is that of mixed stromal tumours that presented with features of gastric outlet obstruction, and the patient did well after surgery.
