The tumor is firm

Introduction Thyroid tumors are common and frequently-occurring diseases, most of which are benign lesions, and a few are cancers, which are divided into benign and malignant categories. The cause is unclear, and the pathological changes are thyroid follicular hyperplasia and thyroid tissue enlargement. It is soft in nature and hard in nature. The incidence of the disease varies greatly depending on the region and gender. In general, the incidence of this disease is high in areas with iodine deficiency in the plateau; in terms of gender, the incidence of benign thyroid tumors in women is 2-4 times higher than that in men. It can be single or multiple.

1, benign thyroid tumors in addition to functional autonomic thyroid tumors, most see thyroid solitary nodules, a few are multiple nodules. The course of the disease is slow, and there may be no clinical symptoms in the clinic. Most of them are in the months to years or even longer. Because of slight discomfort or the mass of the mass reaching 1cm or more, it is found that there is no symptom and it is B-ultrasound during routine physical examination. Found a neck lumps. Most of them are single-shot, round or oval, with smooth surface, clear boundary, solid texture, no adhesion to surrounding tissues, no tenderness, and can move up and down with swallowing. Tumors are usually in the order of a few centimeters, which is rare. Large tumors can cause compression of adjacent organs, but do not invade these organs, such as compressing the trachea, causing the organs to shift. A small number of tumors due to intratumoral hemorrhage suddenly increased with local pain.

2, functional autonomic thyroid adenoma is more common in women, patients often have a long history of thyroid nodules, early asymptomatic or only mild palpitation, weight loss, fatigue, with the development of the disease, patients with varying degrees of thyroid Symptoms of poisoning, most patients have symptoms of hyperthyroidism, and individual hyperthyroidism can occur.

3, part of the thyroid adenoma can be cancerous, the cancer rate is 10-20%.

The possibility of cancer should be considered if:

<1> The tumor has recently increased rapidly.

<2> Tumor activity is limited or fixed.

<3> There are pressure symptoms such as hoarseness and difficulty in breathing.

<4> The tumor is hard and the surface is rough.

<5> There is swelling of the neck lymph nodes.

Differential diagnosis

Benign: Most of the neck masses are single-shot, slow-growing, and may have compression symptoms when large. The masses move up and down with swallowing, smooth, soft texture, round or oval, which can cause hyperthyroidism. When the tumor is small, it can be reduced or disappeared by the general treatment instrument; when the tumor is too large, it should be surgically resected and then irradiated, which can achieve anti-inflammatory, analgesic, swelling, accelerate wound healing, prevent infection and scar. .

One-tenth of benign thyroid tumors can develop malignancy, and malignancy may also be associated with radiation exposure. Malignant thyroid tumors are classified into papillary adenocarcinoma, follicular adenocarcinoma, undifferentiated carcinoma, medullary carcinoma, squamous cell carcinoma, and lymphoma. There is a lump in the neck of the thyroid or adjacent area, and the texture is hard and not flat. There are no obvious symptoms in the early stage, hoarseness in the late stage, difficulty in breathing or swallowing, pain in the pillow or shoulder, diarrhea, palpitations, facial flushing and decreased blood calcium.
