title: Retroperitoneal laparoscopic management method of Castleman's disease in the adrenal gland: two cases report and review of the literature.
abstract: OBJECTIVE
  Castleman's disease (CD) is a rare and complex disease of lymphoid tissues typically involving a mediastinal mass. CD in the adrenal area is an even rarer occurrence. In the present study, two extremely rare cases of adrenal Castleman's disease at our hospital are reported, and the relevant literatures were reviewed. Significant findings: A 51-year-old woman had abdominal pain for 1 month. Physical examination revealed a mass in the left abdominal. A computed tomography (CT) scan confirmed the presence of the mass. Additionally, a left suprarenal mass was detected in a 56-year-old male patient during a regular medical checkup. He had no symptoms when he arrived at our hospital. The two patients underwent mass excision via a retroperitoneal laparoscopic approach. Postoperative histopathological examination of both patients' specimens suggested a diagnosis of the hyaline vascular-type of CD.
  
  
  CONCLUSIONS
  These two rare cases confirm that CD can occur in the adrenal gland area. In addition, we also demonstrate that retroperitoneoscopic surgical management is effective in the treatment of the disease.
