Carcinoma stomach, GIST, SchwannomaAbstract
Carcinoma stomach- Captain of men of death, is the first diagnosis we have across any patient presenting with pallor, epigastric lump and loss of appetite. We present the case of a 47 year old lady with upper abdominal discomfort, anemia and a lump in the upper abdomen and family history of carcinoma stomach, suspected even intra operatively to have carcinoma or gastro intestinal stromal tumour(GIST) of stomach, to be surprised by the histopathology of a benign schwannoma. GIST, a more common pathology of stomach, has malignant behaviour upto 30%. On the other hand, schwannomas are more benign and have excellent prognosis. There lies the importance of differentiating the two.
