A CASE OF LUNG CARCINOID TUMOR, SUCCESSFULLY TREATED WITH BRONCHOSCOPIC CRYOSURGERY IN THAILAND

SEPTEMBER 2015 - VOL.10 | CASE REPORT

A lung carcinoid tumor is a rare malignant neoplasm. The clinical presentation depends on the characteristics of the tumor, its location and hormones secreted. The most common symptoms are cough, wheezing, chest pain, hemoptysis and dyspnea. Diagnosis can be established through radiographic images, biopsy of the tumor with tissue analysis supplemented by blood tests. In previous years, surgery has been the gold standard in treating carcinoid tumors. However, recently, there have been several studies conducted in the efficacy of the use of bronchoscopic methods such as cryosurgery in completely extracting and treating lung carcinoid tumors without metastases. This case report’s objective is to illustrate that cryosurgery should be considered as the new gold standard in treating lung carcinoid tumors.
