Bronchoscopic treatment with argon plasma coagulation for recurrent typical carcinoids: report of a case.

Carcinoid tumors are recognized as a low-grade malignancy. Recurrence of bronchopulmonary typical carcinoids is extremely rare. We herein report a case of recurrent multiple intraluminal bronchial typical carcinoids that were successfully removed using argon plasma coagulation by bronchoscopic approach. A 48-year-old man, who had undergone resection of a pulmonary typical carcinoid 8 years previously, suffered from a productive cough and hemosputum for a month. Bronchoscopic examination revealed multiple intraluminal bronchial polypoid tumors. Based on histopathological findings, we diagnosed recurrence of typical carcinoids. The patient underwent argon plasma coagulation (APC) treatment by bronchoscopic approach several times. APC treatment is considered to be a safer method than conventional bronchoscopic treatment with neodymium-yttrium aluminum garnet (Nd-YAG) laser or electrocautery. After a series of treatments, his symptoms completely improved and no recurrence was found during 10 months of follow-up.
