Cavernous hemangiomas can arise nearly anywhere in the body where there are blood vessels. The primary hemangioma of the thyroid gland is extremely rare, and only a few cases have been previously reported. The true incidence of cavernous hemangiomas is difficult to estimate because they are frequently misdiagnosed as other venous malformations. We will present 4 cases from the age of 38 to 72 years old, diagnosed with cavernous hemangiomas. All 4 cases are women and the diagnosis was established after total thyroidectomy by histopathological examination. They clinically present as asymptomatic cervical tumors, are occasionally fast-growing, especially if intratumoral bleeding is present.
