RESUMEN
Bronchial carcinoid tumors are rare neuroendocrine neoplasms that arise from the Kulchitsky cells of the bronchial epithelium. These tumors can manifest as central carcinoid tumors, pulmonary carcinoid tumorlets, or peripheral carcinoid tumors. Occasionally, the peripheral carcinoid tumors produce corticotropin and result in Cushing's syndrome. Herein we report the first case of Cushing's syndrome associated with a peripheral pulmonary carcinoid tumor that was excised by video-assisted thoracoscopy. After excision, the patient had complete remission. Video-assisted thoracoscopy may be ideal for resecting a peripheral pulmonary carcinoid, especially in patients with debilitation but no evidence of metastasis.

Bronchogenic cysts (BCs) are uncommon congenital anomalies. Due to the inherent complications, the mere presence of a BC should warrant surgical therapy. Partial excision of these structures leads to recurrence. Complete surgical excision using a thoracotomy or video-assisted thoracic surgery is the goal. We report a case of recurrent bronchogenic pseudocyst 24 years after initial excision. This case supports the argument for complete surgical excision of BCs at the time of diagnosis.

Early onset aortic prosthetic valve endocarditis with annular extension of the infectious process remains a highly lethal disease. Destruction of the annular tissue requires complex techniques for repair. The most challenging situation is associated with destruction and fistula formation at the left fibrous trigone. We report a technique using the anterior mitral leaflet to repair an aorto-atrial and aorto-ventricular fistula. This technique places autologous tissue from the anterior leaflet of the mitral valve against the infected area, and may decrease the risk of reinfection.
