Castleman disease: Report of a case and review of literature on role of preoperative embolization

Retroperitoneal paraduodenal unicentric Castleman disease: case report and review of the literature

Castleman disease is a rare and benign disorder, characterized by enlarged lymph nodes and angiofollicular lymphoid hyperplasia. We report a case of a 57-year-old male, who was admitted to our surgical department because of a retroperitoneal nodular mass measuring about 4 cm in maximum diameter, incidentally discovered on a radiologic exam performed for the onset of vague abdominal pain with posterior irradiation. The patient was subdue to laparoscopic removal of the mass and no intra- and post-operative complications were recorded. Histologic diagnosis of hyaline-vascular variant of the Castleman disease was confirmed. Only two cases have been found in the literature reporting the paraduodenal unicentric Castleman disease localization like our case. Although rare, the Castleman disease must be considered in the differential diagnosis among all the lymph nodes diseases, for avoiding improper therapies.

[Diagnosis and surgical treatment of a patient with Castleman disease]

Castleman disease (CD) is a benign lymphoproliferative disease. Small prevalence and diverse clinical course of disease makes it difficult to standardize diagnostics and treatment. Currently, the number of CD patients has increased with improvement in the quality of examination. Therefore, differential diagnosis of this disease is important. We present a young patient with CD and retroperitoneal non-organ neoplasm. Despite a thorough preoperative examination, the final diagnosis was established only after histological examination of surgical specimen. We discuss the diagnosis and surgical treatment of a patient with unicentric type of CD.
