Overview

Other diagnostic studies for glucagonoma include venous sampling after a selective injection of a stimulating secretin. Biopsy, which demonstrates epidermal necrosis, subcorneal pustules, either isolated or associated with necrosis of the epidermis, confluent parakeratosis, epidermal hyperplasia and marked papillary dermal angioplasia, and suppurative folliculitis.

Other Diagnostic Studies

Invasive investigations may be needed to localize tumors at particular regions of the pancreas for treatment planning.

Arterial stimulation venous sampling

Transhepatic portal venous sampling involves a selective injection of a stimulating secretin for glucagonoma into arterial supply of the pancreas with a sampling of the hepatic veins. It is highly sensitive.[1][2]

Biopsy
