case_images: fig2-2050313X221147196
case_images: On macroscopic examination, the spleen measured 10 x 6 x 4 cm3 (Figure 2(a)). The cut section showed brown-red tissue and a yellowish-white tumor with a diameter of 3 cm (Figure 2(b)). On microscopic examination, multiple cystic structures with variable sizes lined by flattened endothelial cells (Figure 2(c)). Immunohistochemical stains showed the cells were positive for CD34 (Figure 2(d)), and negative for CK AE1/AE3, P63, desmin and Ki67.
