A Case of Cecal Cancer Invading the Abdominal Wall Diagnosed After Detection of Pus Discharge from the Operative Wound of a Previous Appendectomy

Abstract

An 83-year-old female patient visited our hospital with the chief complaint of pus discharge from the operation wound of an appendectomy performed when she was 17 years old. The patient was admitted to the hospital due to ileus. Barium enema showed irregular stenosis at the cecum, however, no communication was observed from the skin to the cecum based on fistulography. An Abdominal computed tomography scan showed a tumor 50 mm in size located in the ileocecal region and invading the abdominal wall just below the wound. A diagnosis of cecal cancer invading the abdominal wall was made, and a right hemicolectomy was performed with excision of the abdominal wall including the operative wound of the appendectomy and D3 lymph node dissection. Pathologically, the tumor was tub1, SI (abdominal wall), ly0, v0, N0, and fStage Ⅱ. The patient received curative pathological resection (pCurA). No signs of recurrence have seen in the 5 years since the operation. A case like the present one may be considered to be rare, in which cancer invasion was detected in a patient with the chief complaint of pus discharge from a previous operative wound.
