CARCINOID TUMOR IDENTIFIED WITHIN A SEQUESTERED LUNG

TOPIC: Lung Cancer TYPE: Fellow Case Reports INTRODUCTION: Pulmonary sequestration is the second most common pulmonary congenital abnormality and rarely associated with malignancy. We present a case of young woman hemoptysis found to have two rare concurrent lung pathologies: carcinoid tumor within sequestration. CASE PRESENTATION: 21 year old female presents following an episode sudden onset hemoptysis. Patient's medical history was notable for prior episodes pneumonia in her teenage years. A CT chest angiogram obtained revealed right upper lobe highly vascular mass-like consolidation. This followed by bronchial artery angiography which identified torturous arterial blood supply abnormal area parenchyma large draining vein. Patient underwent 90 minute robotic resection aberrant suggestive Pathology consistent typical tumor. discharged home on post operative day 1 follow up imaging has not shown recurrence. DISCUSSION: describes tissue anomalous systemic supply. It accounts approximately 6% all abnormalities predominantly affecting males 4:1. Typically patients remain asymptomatic this finding incidentally noted imaging. If superinfected can be confused consolidative pneumonia. Therefore, presentation adults includes recurrent infections These features are also shared primary Typical tumors indolent neuroendocrine that progress slowly metastasize. Although rare, accounting 1% cancers, it malignancy children adolescents. The mainstay treatment, like sequestration, involves resection. Further staging pathological findings determine additional therapies. demonstrates considerations required diagnostic approach poorly characterized lesion when patient life threatening condition such as initial showed lesion, however degree only appreciated angiography. Endobronchial biopsy carried increased risk hemorrhage may been inadequate diagnose underlying surgical favored. CONCLUSIONS: uncommon highlights importance carefully considering these atypical diagnoses multidisciplinary successful diagnosis treatment. REFERENCE #1: Corbett HJ, Humphrey GM.
