case_images: On gross pathological examination, an 11.5 x 7.5 x 7 cm solid lobulated mass, which was originated from the parietal layer of anterior tunica vaginalis and growed into scrotal sac was noted (Figure 1).
case_images: Hypocellular and highly myxoid lesion consisting of small spindle cells and blood vessels of varying sizes. A black arrow in (a) points to the mesothelial lining of parietal tunica vaginalis ((a) H&E: x100; (b) H&E: x40; (c) H&E: x200).

case_images: Microscopical examination showed that the lesion was hypocellular and composed of short spindle cells within abundant myxoid extracellular matrix, which was collagenous in some areas (Figure 2).
case_images: Neoplastic cells showing diffuse (a) estrogen receptor, (b) CD34 and (c) focal desmin immunoreactivity (immunohistochemistry: (a) anti-ER Ab, x200; (b) anti-CD34 Ab, x400; (c) anti-desmin Ab, x200).

case_images: fig3-2050313X17712090
case_images: Immunohistochemical studies revealed diffuse and strong expression of CD34, estrogen receptor (ER) and progesterone receptor (PR) by neoplastic cells (Figure 3).
