👉 Hernioids are a type of benign tumor that occurs in the lining of blood vessels. They can be either solid or fluid, and they often appear as small protrusions or masses on the surface of the skin or other tissues. Hernioids may cause pain, swelling, and discoloration when they become larger or if they rupture. They are usually treated with surgery and radiation therapy to control their size and prevent them from causing further complications.
