A 66-year-old female received a health screening and an abdominal ultrasonography revealed a retroperitoneal tumor.The 25×20mm tumor was located in the retroperitoneal space behind the pancreatic body. The tumor was homogenouslyenhanced in the computed tomography, and magnetic resonance imaging showed low intensity in T１ and iso-intensity inT2. In order to obtain a definite diagnosis and perform adequate treatment, a diagnostic laparoscopy was performed. Theresected tumor proved histopathologically to be a unicentric Castleman’s disease with hyaline-vascular type. The postoperative course was uneventful and the patient was discharged on postoperative day 8. No recurrence has been detectedat 10 months follow-up. It is very difficult to diagnose a small retroperitoneal tumor. The diagnosis was achieved only bythe histologic evaluation of the surgical specimen. The laparoscopic approach enabled the resection of the lesion (withconsequent histological diagnosis) and exploration of the peritoneal cavity with the advantages of minimal invasiveness.The pathology was totally resolved, with satisfactory results in terms of recovery, postoperative pain, and cosmetics.
