Thyroid adenoma

Overview of thyroid adenoma is the most common thyroid thyroid tumors. The disease in the country sporadic presence in the area of endemic goiter prevalence slightly styles. Cause pathogenesis of thyroid adenoma pathology can be divided into follicular adenoma and papillary cystic adenomatoid two. The former are more common. Cut surface light yellow or scarlet, with a complete envelope. The latter than the former rare features of papillary protrusions formed. Clinical manifestations in patients with more female, age often below the age of 40, most are single-vivo thyroid nodules. many were rare. Park tumor was egg-shaped or round in shape, and confined to the gland side, the texture than the surrounding thyroid tissue shape and slightly harder, smooth surface, a well - no tenderness, with the next swallow, slow growth, the majority of patients without any symptoms. Papillary cystic adenomatoid sometimes vascular wall can rupture occurred intracystic hemorrhage. At this time, the tumor volume in a short period of time increases rapidly, and so have local flu. Diagnosis of thyroid adenoma diagnosis based on history, physical examination, isotope scanning and "B" Ultrasound and other tests to determine. But thyroid adenoma with other differentiated thyroid nodules. Thyroid adenoma and nodular goiter single nodules in clinical sometimes difficult to identify. 2:00 differential for the following reference : ① thyroid adenoma years remain single, nodular goiter single node for a period of time, many more into nodules. ② during the two are clearly different, adenoma complete envelope, the normal surrounding tissues, clear distinction; nodular thyroid nodules no single complete capsule and the surrounding normal thyroid tissue. The following can be used as identification with thyroid cancer reference : ① child or over the age of 60 male patients should consider the possibility of thyroid cancer, and thyroid adenoma occurred in the following 40-year-old female patients. ② nodular thyroid cancer surface uneven, with hard, swallowing activity at the small, and in a short period of time grew faster. Sometimes thyroid nodules smaller, it can lay hands on the same side of his neck and swollen lymph nodes. Thyroid adenoma smooth surface texture is relatively soft, the next time swallowing activity, slow growth, no more neck lymph nodes. ③ iodine 131 or radionuclide scanning photographic γ thyroid cancer manifested as cold nodules and thyroid adenoma temperature can be in the form of nodules, cool or cold nodules nodules. And cold nodules "B" ultrasound examination for cystic more performance. ④ surgery thyroid cancer can be seen not coated with the surrounding tissue adhesions or infiltration performance and thyroid adenoma more complete capsule and the surrounding normal thyroid tissue.
