Castleman disease is a rare hyperplastic disorder that can affect any group of lymph nodes. Clinically and radiologically, it can mimic a malignancy and can only be diagnosed by histopathological examination. Castleman disease should be considered as one of the differential diagnosis for a patient presenting with a retroperitoneal mass. Complete surgical excision is usually curative; a preoperative diagnosis by biopsy can avoid extensive surgery for this condition. In this case report, we present a 40 year old female with a retroperitoneal mass, which was clinically suspected to be a malignancy. Complete surgical excision was done and histopathological examination of the mass revealed a unicentric Hyaline vascular type of Castleman disease. Keywords: Castleman disease, Hyaline vascular type, Giant lymph node hyperplasia, Plasma cell type, retroperitoneal mass, Unicentric.
