A case of castleman disease in lesser omentum removed by laparoscopic operation

Abstract

A 44–year–old male patient went through a physical check–up and was pointed out to have a mass with calcification near the lesser curvature of stomach. CT and MRI study revealed a well circumscribed mass, like spleen, of 3cm in diameter with calcification inside. With a suspected diagnosis of Castleman disease in the lesser omentum, based on the image studies, excision of the tumor was performed under laparoscopic surgery. The excised specimen was a solid mass with yellow–whitish cut surface and the pathological diagnosis was hyaline vascular type Castleman disease.
