case_images: The CT scan revealed a well circumscribed 4x3.5 cm sized, soft-tissue density, lobulated round mass in the mid-abdominal cavity (Fig. 2).
case_images: A. Macroscopically, the mass was egg shaped, and it measured 5.0x4.5x4.0 cm in size. B. The cut surface showed a well defined homogenous brownish mass with multifocal whitish foci.

case_images: It was hard and surrounded by a thin fibrous capsule (Fig. 3A). On sectioning, the cut surface showed as a well defined homogenous brownish mass with multifocal whitish foci (Fig. 3B).
case_images: A. On histopathologic examination, lymphoid follicles with centrally located, thick blood vessels and interfollicular nodular hyalinizing fibrosis (hematoxylin and eosin, 100x). B.

case_images: On histopathologic examination, this mass showed lymphoid follicles separated by bands of connective tissue with centrally located thickened blood vessels, and it was compatible with the hyaline vascular type of Castleman's disease (Fig. 4A, 4B).
