Abstract

<p>A 60-year-old woman visited our hospital due to vomiting, and abdominal CT showed findings of suspected colorectal obstruction due to descending colon cancer, and the liver had multiple low-absorption nodules with suspected cysts. Forty days after a colonic stent was placed for colorectal obstruction, laparoscopic left hemicolectomy was performed. During the operation, two 5-mm, white nodules suspected to be metastatic liver tumors were found on the surface of liver S5 and S8. EOB-MRI showed only two suspected metastatic liver tumors at the same site. Two months after the initial surgery, laparoscopic partial hepatectomy was performed. Histopathologically, these nodules proved to be hepatic reactive lymphoid hyperplasia (RLH). RLH is a benign tumor, and there have been many reports in the lungs, orbits, and skin. However, it is rare in the liver, especially in multiple cases. There is little need to treat hepatic RLH, but it is difficult to follow up because of the difficulty of making a preoperative diagnosis and the difficulty of differentiating it from malignant liver tumor. A case of multiple nodules of hepatic RLH suspected to be metastatic liver tumors of colorectal cancer is presented along with review of the relevant literature.</p>
