A lump in the neck that moves when touched is most commonly a swollen lymph node in the neck, which can be secondary to a local soft tissue infection, or secondary to a viral infection or upper respiratory tract infection, and the patient will also have pain, cough, and sputum, and should be treated systematically with anti-inflammatory or antiviral therapy, and the symptoms can gradually improve. It can also occur in the thyroid gland, mainly as a mass in the front of the neck, which can be investigated as a locally elevated mass that moves well up and down with swallowing, with a smooth surface, clear borders and good mobility, most commonly as a thyroid adenoma, especially in young female patients. The most effective treatment is surgery to remove the lesion under local anesthesia. The cause of thyroid adenoma is related to the hyperplasia of the thyroid follicles.
