Mesenteric Mixed Type of Castleman Disease: A Report of a Rare Case

Castleman disease is a rare type of lymph node hyperplasia primarily affecting the mediastinum, with mesenteric localization being extremely uncommon. It is classified into solitary and multicentric forms. In this case report, we present the case of a 46-year-old female patient in whom an incidental mesenteric mass was discovered during the workup for a ventral hernia. The mass was completely excised, and the histopathological examination confirmed the diagnosis of mixed-type Castleman disease. Surgery is the treatment of choice for localized forms of this condition, and histological examination is crucial in confirming the diagnosis.
