case_images: (a) Gross photograph of right ovary showing solid and spongy tan-colored lesion with hemorrhagic specks. The adjacent area showing luteinization (yellowish discoloration-arrow). (b) Microscopic examination scanner view showing vaguely lobulated lesion with adjacent ovarian parenchyma shows stromal luteinization (H and E, x4)

case_images: The residual ovary showed cystic change with yellowish discoloration [Figure 1a]. The residual ovarian stroma showed stromal luteinization [Figure 1b and 2a].
case_images: (a) Microscopic examination showing closely packed capillaries lined by bland hobnail endothelial cells. Mononuclear cells are seen within the lumen of capillaries and in the stroma (H and E, x20). (b) Immunohistochemistry - CD31 showing intense membranous positivity for endothelial cells (x20)

case_images: The residual ovarian stroma showed stromal luteinization [Figure 1b and 2a]. Immunohistochemically, the endothelial cells showed strong positivity for CD31 [Figure 2b] and CD34 confirming the vascular origin of the lesion.
