[A Case of Successful Additional Resection for Subcutaneous Local Recurrence of Cecal Cancer with Subcutaneous...

We report a rare case of subcutaneous local recurrence of cecal cancer with subcutaneous abscess formation, successfully managed by additional resection. An 86-year-old woman underwent ileocecal resection with partial peritoneal resection for cecal adenocarcinoma complicated by a subcutaneous abscess. Postoperative chemotherapy was administered, and the patient was followed up regularly. Five months later, a painful subcutaneous mass appeared in the right lower quadrant. Imaging studies, including CT and PET-CT, indicated subcutaneous local recurrence. Surgical excision was performed due to symptom progression. Histopathological and immunohistochemical findings confirmed recurrent adenocarcinoma of cecal origin. The patient has remained recurrence-free for 17 months.
