腸腰筋膿瘍を合併した下行結腸癌の1例

A 62-year-old man was admitted to another hospital because of hip joint pain and gait disturbance, and he was referred to our hospital for a left psoas abscess. Drainage for the abscess resulted in well control of systemic inflammation. A diagnosis of descending colon cancer was made based on close examination. On the 24th day after the admission, resection of the descending colon was performed. The tumor had invaded the retroperitoneum, but no direct invasion into the iliopsoas muscle was confirmed. The patient’s postoperative course was uneventful. The patient was discharged from the hospital 18 days postoperatively. Rare cases of a carcinoma of the descending colon complicated with a psoas abscess reported in Japan, including our case, are reviewed in this paper.
