Primary colonic liposarcoma presenting as intussusception: A case report from the Kashmir valley

Abstract

Rationale: Soft tissue sarcoma (STS) arises from mesenchymal tissue and can occur at any anatomic site and age. These tumors can originate from skeletal muscle, adipose tissue, vascular tissues, or connective tissues. Liposarcoma (LPS) is the most frequent type of sarcoma and is commonly found in the retroperitoneal region. Patient Concerns: A case of colonic liposarcoma in a young female patient presented with sub-acute intestinal obstruction due to intussusception. The patient was only 17-years-old, much younger than the average age of occurrence, and thus represents the first case report of primary colonic liposarcoma in this age group. Diagnosis: The patient was resuscitated and subjected to standard investigations. An ultrasonography abdomen/ pelvis revealed colo-colic intussusception and CECT abdomen showed evidence of an enhancing mass within the lumen of the transverse colon. Interventions: The patient was subjected to exploratory laparotomy with segmental colonic resection and primary colo-colic anastomosis. Outcomes: The histopathology and immunohistochemistry revealed the morphology of high grade colonic liposarcoma. The patient is doing well eight months after surgery and is being monitored on a regular basis. Lessons: The primary gastrointestinal liposarcoma tumors are uncommon and colonic variants are extremely rare, especially in the second decade of life, and limited to case reports which can be counted on fingertips. Surgical resection with negative margins is the only curative treatment.
