case_images: Computed tomography scans (a) without contrast and (b) with contrast before the surgery showed a hypodense mass in the epigastric area between the liver, kidney, and pancreas. (c) Postsurgical contrast-enhanced computed tomography.

case_images: Also, a 5 cm simple splenic cyst was reported (Figure 1).
case_images: Histologic examination showed pseudopapillary (a, b) and solid components (c) of mildly pleomorphic epithelial cells with areas of necrosis and foamy histiocytes accumulation (d). Some tumoral cells contained hyaline globules within their cytoplasms (c).

case_images: Microscopically as shown in Figure 2, the lesion was composed of a well-circumscribed encapsulated neoplasm with solid and pseudopapillary components and large areas of necrosis.
case_images: Immunohistochemistry examination: positive staining for (a) vimentin, (b) B-catenin, and (c) progesterone receptor (PR).
