Carcinoids account for approximately 2% of all lung tumors, and the atypical carcinoids (ACs) are much rarer than typical carcinoid. Here, we report a rare case of AC tumor of the lung. A 50-year-old female patient presented with left-sided chest pain for 1 year, cough for 6 months, and loss of appetite for 6 months. Contrast-enhanced computed tomography scan of the thorax revealed an ill-defined heterogeneously enhancing soft-tissue attenuation lesion in the mediastinum following which transthoracic biopsy was done. Histomorphology and immunohistochemistry were consistent with AC, a neuroendocrine tumor. Combination chemotherapy consisting of cisplatin and etoposide was administered as initial chemotherapy.
