INTRODUCTION: Primary leiomyosarcoma (LMS) of the colon is a rare and aggressive gastrointestinal tract tumor, associated with poor prognosis. Case presentation and methods: We present the case of an asymptomatic patient who was diagnosed with a low sigmoidal stricture on routine colonoscopy. Although biopsies were inconclusive, an oncological partial mesorectal excision (PME) was performed due to the malignant macroscopic aspect. Pathological examination surprisingly revealed a LMS. The patient received no adjuvant chemo- or radiotherapy, but is seen on regular follow-up. We review the literature on leiomyosarcoma of the colon: its diagnosis, treatment, and prognosis. RESULTS: Up until now the patient shows no sign of recurrence, 15 months postoperatively. CONCLUSION: Radical resection is the treatment of choice for primary leiomyosarcoma of the colon and long-term follow-up is needed to evaluate metastatic disease or local recurrence.
