Ileocolic intussusception as a presenting sign of primary lymphoma of the colon.

INTRODUCTION

Intussusception is a rare phenomenon in adults. It is caused mainly by malignant neoplasm. Primary lymphoma of the colon is a rare malignancy of the large intestine. The association of intussusception in adult and primary colorectal lymphoma is a diagnostic challenge, since they occur with a variety of atypical symptoms.

CASE OUTLINE: We report a case of ileocolic intussusception in a 26-year-old man induced by primary lymphoma of the cecum. He was admitted to our hospital for incomplete intestinal obstruction. After thorough diagnostic work-up (plain abdominal radiography, abdominal ultrasonography, multi-slice computerized tomography, colonoscopy with biopsy), the patient underwent surgery. Intraoperative findings confirmed lymphoma as the cause of intussusception. The right hemicolectomy was carried out with end-to-side ileo-transverse anastomosis.

CONCLUSION

Primary colorectal lymphomas should be considered in differential diagnosis of intussusceptions in adults. The treatment of choice is a radical resection where all oncological standards must be fulfilled.
