Introduction: We report one case that the patient who had sigmoid adenocarcinoma 13 years ago post left colectomy and chemotherapy therapy had one mass of encapsulated fat necrosis extremely similar to malignancy. Because of the special image, we though this case should be published. Case
Presentation: One 75 years old male oriental had a history of hypertension and sigmoid adenocarcinoma, stage IV with lung metastasis. He received left colectomy and chemotherapy therapy 13 year ago. He returned our hospital because acute abdominal pain. The computed tomography showed a fusiform shaped well encapsulated mass with increased soft tissue density in subcutaneous regions of right pelvis wall region. This looked like infectious process or malignant recurrent. Pathology specimen reported soft tissue and fat necrosis.
Conclusion: Local abdominal encapsulated fat necrosis could be mimicking local colon cancer recurrent. Laparoscopy or excisional biopsy for taking pathology specimen can be used for the same cases for study and diagnosis.
