Abstract

Adrenal rest tumors are aberrant adrenocortical tissue which has been most commonly described in abdominal and pelvic sites. To our knowledge, there has been no previous description of an adrenal rest tumor of the greater omentum. We present a case of a pathologically confirmed adrenal rest tumor of the greater omentum in a 76-year-old man.

Keywords: Adrenal Rest Tumor, Greater Omentum, Computed Tomography, Exophytic Hepatocellular Carcinoma

Figures and Tables

Fig. 1

76-year-old man with adrenal rest tumor of the greater omentum.

A. Contrast-enhanced CT scan obtained during portal phase shows heterogeneous enhancing mass (arrow), seems to adhere to gastric wall.
B. Mass (arrow) abuts the gastric fundus wall in coronal image.

The upper gastrointestinal series shows mass lesion (arrows) at outside of gastric fundus.

76-year-old man with adrenal rest tumor of the greater omentum.

A. Contrast-enhanced CT scan obtained during arterial phase shows feeding vessel (arrow) branched from left hepatic artery.
B. Sagittal image shows feeding vessel (arrow) and mass (M) abuting the gastric wall.

Fig. 4

76-year-old man with ruptured adrenal rest tumor of the greater omentum.

Contrast-enhanced CT scan shows obscured boundary of mass around fundus of stomach and abundant hyperattenuated fluid in peritoneum.

Fig. 5

76-year-old man with adrenal rest tumor of the greater omentum.

A. The microscopic picture of the tumor shows proliferation of large polygonal cells with abundant eosinophilic cytoplasms and atypical nuclei. The tumor cells are arranged around the slit like sinusoidal vessels without fibrosis (Original magnification, ×200 Hematoxylin & Eosin stain).
B. Electron micrograph from paraffin embedded tissue of the tumor (Original magnification, ×5000 uranyl acetate-lead citrate stain). Multiple oval to round mitochondria with electron dense inclusions in the cytoplasm (arrow) suggest that the tumor cells are originated in adrenal gland (M: mitochondria, N: nucleus, L: lipid vacuole).
