somatotroph adenoma

A somatotroph adenoma is a benign tumor that develops in the anterior lobe of the pituitary gland. These tumors arise from somatotroph cells, which are responsible for producing growth hormone (GH).

When somatotroph adenomas cause excess GH production, it leads to conditions like gigantism in children and acromegaly in adults. Acromegaly is characterized by the enlargement of extremities, facial features, and internal organs due to the overgrowth of cartilage, muscle, and skin. This excess GH can also lead to other health issues, including diabetes mellitus, high blood pressure, and an increased risk of colon cancer. Treatment typically involves surgical removal of the tumor, radiation therapy, or medication to block GH's effects.12
