(A, B) Magnetic resonance imaging scan of abdomen revealed a large well-defined suprarenal mass that measured 12x10x8.3 cm displacing the right kidney inferiorly and inferior the right lobe of liver and close to the porta hepatis, with evidence of cystic changes, fatty component, and calcification.

Magnetic resonance imaging scan of pelvis and abdomen revealed left ovarian mass 10x8x7 cm and a large well-defined suprarenal mass that measured 12x10x8.3 cm displacing the right kidney inferiorly and inferior the right lobe of liver and close to the porta hepatis (Figure 1).
Histopathology of the initial left ovarian tumor demonstrating immature teratoma composed of mixed immature and mature elements including (A) primitive neuroepithelial elements with rosettes formation (H&E, 4x), (B) focal immature cartilaginous elements (H&E, 4x), and (C) benign mature epithelial elements forming papillary structures adjacent to mature neuroglial tissue (H&E, 4x).

The previous histopathology was reviewed in our center, and it was consistent with immature teratoma, grade 3 (Figure 2).
Histopathology of the recurrent tumor revealed heterogeneous mature elements including (A) epidermal cyst lined by mature keratinized squamous epithelium and filled with keratinous debris (H&E, 4x), (B) dermoid cyst lined by benign squamous epithelium surrounded by mature fibroadipose tissue with embedded adnexal glands (H&E, 4x).
