Primary mesenteric gastrointestinal stromal tumour with concomitant mesenteric tuberculosis: Careful histopathology is essential.

Gastro-inestinal stromal tumours (GISTs) comprise 1-2% of all gastrointestinal (GI) tumours. The mesentery, retroperitoneum and omentum are common sites of extra-gastrointestinal stromal tumours (E-GISTs). Isolated involvement of the mesentery by tuberculosis (TB) without any evidence of pulmonary disease is quite unusual. Here we report a case of an E-GIST arising from the small bowel mesentery in a 60-year old female where an incidental concurrent mesenteric tuberculosis was diagnosed following surgical resection.
