Pulmonary hamartoma

Overview of pulmonary hamartoma in the incidence of lung tumors accounted for the first one. Etiology of pulmonary hamartoma the sources and causes of morbidity is not very clear, relatively easy to accept the hypothesis that hamartoma is a bronchial of embryonic development in reverse and peeled off period, the normal lung tissue enveloping, This part of the growth has been slow, it may not grow in a certain period of time, gradually developing tumor formation. Hamartoma most of the 40 years after the fact that the incidence support this hypothesis. Pathological changes hamartoma pathological features of the normal tissue is not normal composition and arrangement, Such abnormal histological organ may be in size, structure or maturity level of insanity. Hamartoma key ingredients including cartilage, fat, muscle, glands, epithelial cells, sometimes bone or calcified. Yet to see a hamartoma malignant reported. Hamartoma typically real dense spherical, oval, it can also be a lobulated or nodular, Most of 3 cm in diameter on the next. Diagnosis of hamartoma diagnosed mainly by X-ray examination, the majority of the conventional X-ray inspection discovered accidentally. X-line performance for the dense shadow of a shadow can be uneven, but can also calcification, Popcorn video showed calcification-shaped logo, peripheral density is relatively low, it may adipose tissue. Popcorn is the levy lung hamartoma characteristic performance, but it is a rare pulmonary hamartoma alone (Figure 1). Pulmonary hamartoma typically single, multiple persons are extremely rare, yet reported. Single hamartoma majority of the lung parenchyma type, bronchial cavity type rarely see. On the right side than the left lung, coming to the leaf over leaves, and in part in the right middle and left upper lobe of the tongue. Figure 1 pulmonary hamartoma clinical manifestations hamartoma made abundantly clear in the age of majority above 40 years old, men more than women. Hamartoma majority (about 80%) growth in the peripheral lung, pulmonary close to the visceral pleura, Sometimes prominent in the lung surface, it is not a general clinical symptoms, check-no positive signs. Only when hamartoma develops to a certain size, sufficient to stimulate or bronchial compression caused bronchial stenosis or obstruction, only cough, chest pain, fever, shortness of breath, bloody sputum, or hemoptysis clinical symptoms can arise when the corresponding clinical signs, If wheezing or breathing tube sound. Physical examination found that the treatment of pulmonary hamartoma, in the absence of dynamic observation, and sometimes very difficult to differentiate lung cancer, rapidly increasing short-term pulmonary hamartoma it will be difficult to diagnosis. Therefore, when the clinical and X-ray can not rule out malignancy should be performed as soon as possible. Even benign hamartoma early surgery can be avoided by increased tumor caused by pneumonia, atelectasis, bronchiectasis, and other complications, which might aggravate their condition or complicated. Surgery under general anesthesia, the tumor after thoracotomy in pulmonary surfactant, flaky texture, the surface is not smooth, may find tumor in the lung tissue sliding. Open lung tissue little separation may be excised tumor integrity. Apart from endobronchial - hamartoma, or cancer may not line up, in general, are OK partial resection, or removal of the lung.
