Case presentation: A 65 years old male patient referred to our institute with complaints of vomiting, pain and distention of abdomen .Clinical examination showed rigidity and guarding of abdomen with diminished bowel sounds. Clinically diagnosed as intestinal obstruction. Colonoscopy revealed growth at recto-sigmoid junction. Histopathology of biopsy reported with differential diagnosis. Malignant gastrointestinal stromal tumors (GIST) and Leiomyosarcoma. Immunohistochemistry confirmed the final diagnosis. SMA positive and CD117 negative.
