Glucagonoma is a tumor of the islet cells of the pancreas, which secrete the hormones insulin and glucagon.

Tonsillectomy is surgery to remove the tonsils. These two fleshy oval-shaped pads are located on either side of the back of the throat. Tonsillectomy is needed when the tonsils become infected frequently (tonsillitis) or non recovering infection and because of enlarged tonsils blocking normal breathing and rarely to treat cancer or a tonsil that won't stop bleeding. Tonsillectomy is one of the more common surgeries in children, but it's done less often in adults. Adult patients with swollen, infected tonsils may require a tonsillectomy under general anesthesia if their problem recurs too often.

A skin tag is a common, acquired benign skin growth that looks like a small piece of hanging skin. Skin tags are often described as bits of skin- or flesh-colored tissue that projects from the surrounding skin from a small, narrow stalk. They typically occur in characteristic locations including the neck, underarms, eyelids, and under the breasts (especially where underwire bras rub directly beneath the breasts).

Pruritus (itching) can be a symptom of primary skin diseases or of systemic disease. Skin diseases notorious for causing intense pruritus include scabies, pediculosis, insect bites, urticaria, atopic and contact dermatitis, lichen planus, miliaria, and dermatitis herpetiformis.
