Abdominal contrast-enhanced computed tomography (CT) scan. (a) Cross-sectional (transverse) view: showing a large lesion in the region of left adrenal gland measuring 9.0 x 9.2 x 10.8 cm and demonstrating multiple cystic spaces with thin septations as well as multiple areas of fatty collections and coarse calcifications. (b) Coronal (frontal) view: showing displacement of left kidney inferiorly.

An abdominal contrast-enhanced computed tomography (CT) scan showed a large lesion in the region of left adrenal gland measuring 9.0 x 9.2 x 10.8 cm and demonstrating multiple cystic spaces with thin septations as well as multiple areas of fatty collections and coarse calcifications (Figure 1(a)). The huge space-occupying lesion displaced the left kidney inferiorly (Figure 1(b)).
Mature (benign) cystic retroperitoneal teratoma in the region of left adrenal gland. (a) Grossly, cut-section of the resected mass revealed multilocular cystic spaces, whitish-gray walls, scattered yellowish adipose tissues, mucus secretions, and areas of calcifications. (b) Hematoxylin & Eosin (H&E stain), x20 magnification: a scanning magnification view of the lesion depicting its relationship with the adrenal cortex (open arrows). The lumen [L] is lined by respiratory columnar epithelium. (c) Hematoxylin & Eosin (H&E stain), x40 magnification: a low magnification image of another cystic space lined by mucous-secreting epithelium (solid arrows). The wall is formed by cartilage tissues [C], fat (adipose) tissues [F], and salivary gland tissues (open arrows).

Cut-section of the mass revealed multilocular cystic spaces, whitish-gray walls, scattered yellowish adipose tissue collections, mucus secretions, and areas of calcifications (Figure 2(a)). Microscopically, the walls were largely lined by respiratory columnar and squamous epithelium with various proportions of mature well-differentiated parenchymal tissues derived from the various three germ cell layers (Figures 2(b) and 2(c)).
