The clinical symptoms of parathyroid adenoma are reflected in the following aspects: 1. Parathyroid adenoma is a relatively common benign tumor in clinical practice, usually composed of a mixture of principal cells, eosinophils and transitional eosinophils, and is usually seen in middle-aged and elderly people, with more women than men. 2. Parathyroid adenoma is usually divided into two types, functional and non-functional, while functional adenoma is mainly caused by anxiety, depression, psychosis, drowsiness in the nervous system, bone pain, osteoporosis, pathological fracture in the skeletal system, and anxiety. Parathyroid adenoma is mainly caused by excessive parathyroid hormone, which manifests as anxiety, depression, mental disorder and drowsiness in the nervous system, bone pain, osteoporosis, pathological fracture and bone deformity in the skeletal system, and even fatigue and weakness in some patients.3 Some patients may experience local irritation or pain in the neck, causing symptoms such as hoarseness and slight hypopharyngeal dysfunction. Therefore, if patients have the above symptoms, they must seek medical attention in time for early detection and early treatment, and have better results after surgical removal.
