A RARE CASE REPORT GASTRO INTESTINAL STROMAL TUMOR ( GIST ) IN A JEJUNAL DIVERTICULUM

Abstract

Introduction Jejunal diverticulosis is an
uncommon condition and its association
with gastrointestinal stromal tumor
(GIST) is very rare. We report a rare
case of GIST arising in a jejunal diverticulm
presenting as a pelvic mass.Case
report A fifty year old lady presented with
a mass in the right lower abdomen associated
with pain, vomiting and loss of
weight. Computerised tomography of the
abdomen showed a large, heterogenous
mass arising from the right ovary. At
laparotomy, however, she was found to
have a large lobulated tumor arising from
the jejunum which was resected. The
mucosal surface of the resected jejunum
showed the mouth of the diverticulm harbouring
the tumor. Histopathology was
suggestive of high grade GIST which
was confirmed by immunohistochemistry.
Patient was started on Tab. Imatinib 400
mgday. Conclusion Abdominal cavity
continued to be a pandoras box and
despite improvised imaging studies like
computerized tomography, laparotomy is
the final answer in clinching the diagnosis.
Gastrointestinal stromal tumor( GIST) in a
true jejunal diverticula is extremely rare
and can be confirmed by immunohistochemistry.
