Primary adenoid cystic carcinoma of the lung in 14-year-old boy

Abstract

Abstract We report a young adenoid cystic carcinoma (ACC) case of the lung that was treated with thoracoscopic anatomical segmentectomy. The patient was 14-year-old boy who had a history of a nodular lesion in the left middle lung field on the chest x-ray growing in size. Chest computed tomography (CT) demonstrated a solid 24 mm in diameter nodule in the left S5 region. PET-CT was mild positive. Malignancy could not be excluded based on these findings, so thoracoscopic left lingual (S4+5) segmentectomy was done. Histopathological examination showed ACC. On immunohistochemical analysis, these tumor cells were positive for Thyroid Transcription Factor-1 (TTF-1). This tumor was diagnosed primary ACC of the lung and pT1aN0M0 stage 1A. Because of surgical margin was free, it didn't do radiotherapy and chemotherapy. On follow-up examination three-year postoperatively, he was noted to be in excellent health and no signs of recurrence have been identified. Primary ACCs of the lung are extremely rare lesions and are difficult to diagnose before the surgery. The surgery should be the first therapeutic option. Thoracoscopic anatomical segmentectomy may be the ideal oncologic procedure for patients with small lung cancers and effective means of lung parenchymal preservation in pediatric patients.
