Benign Tumors

Benign Tumors

Only 5% of all primary lung tumors are benign tumors. Half of benign tumors include bronchial adenoma.

Bronchial Adenoma

Lung cancer occurs earlier than the age (30-40 years).


Bronchial glands, mucosa, or epitelyumlarından thrive. Adenoma in approximately 80% of the cases are found in the bronchi. These tumors are partially or completely clog bronchus. Complete blockage occurs when the relevant lobe atelectasis. In some cases, bronchial mucosa in lung tumor development in the right shows parenki-Masina. Bronchial adenoma and normal tissues show a growth of local lung parenkimasına to repel etmeyip devastated. These tumors are very rare in advanced disease, lymph nodes and metastasize to other organs.
Bronchial adenomalarının two major pathological types: (1) carcinoid type (2) Silindroma type.

Adenomalarının covers 90% of all bronchial carcinoid type. Silindroma type is 7%. Mucoepidermoid bronchial adenoma and confused the remaining 3% of the tumors. Adenomalannda bronchial tumor cell growth are similar to each other all the best diferansiye'dir nature.

This type of bronchial adenoma of carcinoid type Carcinoid tumors of the gastrointestinal tract is similar. Tumor cells are small, equal in size. Glandular arrangement of cells shows a pattern. The tumor stroma is a rich vascular structure. Sometimes increases, and the tumor vascular structure very similar to hemanjioma'ya. Because of the richness of vascular network hemoptysis is common in carcinoid tumors.
Carcinoid bronchial adenoma as a rare "carcinoid syndrome"
cause. This fast-growing tumors by sendrom'u, invasive nature and tend to spread hematogenously. External secretion of serotonin in carcinoid syndrome develop tumors has increased. This increase in hypotension, facial syanotik kızarmaları (flashing), dyspnea (bronchospasm), and causes diarrhea.

Trachea and major bronchi bronchial adenoma type Silindroma thrive in this kind. After the re-development is likely to be surgically removed. These are malignant and invade more tweaking nature of carcinoid type. Histologically, the acinar growth in the show.

Clinical symptoms

Bronchial adenomas grow slowly for years show no clinical symptoms. Tumor diagnosed with the disease several times due to a secondary infection or hemoptysis, the clinical, radiographic and bronchoscopic examination regains clarity. These tumors are rich in vascular tissue and bronchoscopy should be done cautiously. More than half of all cases of hemoptysis vardır.Hastaların other complaints of cough, sputum, fever, chest wheezing and chest ağnsıdır. Physical examination findings vary according to the localization of the disease. Regional dullness, decreased breath sounds, wet and dry Railer, similar to those seen with other clinical manifestations of bronchial cancer.

Radiological findings

Small tumors do not radiographic signs. The tumor grows, more likely seen. 80% of these tumors or a large segment of bronchial obstruction was showing bronşlarında full at a time when growth is occurring. During this period there are radiological findings of atelectasis and obstructive pnömonitisin. Repetitive nature of the distal segments of occluded the development of pneumonia, bronchial infections and bronchiectasis occurs.

Progressive bronchial obstruction has not done a full cavity, bronchial adenoma (adenoma central) radiograph around the well-defined, sometimes sliced, appear as soft tissue concentration. Computer tomography shows the tumor better. If necessary, regional and morphological features of the bronkografıyle adenomamn better determined.


Surgery is the treatment of bronchial adenomasmın. The most commonly performed surgery lobectomy. Usually these tumors are not sensitive to radiation therapy. However, radiation therapy, surgical intervention should be attempted in cases not possible. Chemotherapy showed no particular success.
