Figure 1 A 61-year-old woman with PCT and bronchiectasis. Dilated, beaded bronchi and cysts with defined borders can be observed in the lung window CT image (A, white arrowheads). Cord-like shadows can be observed in the mediastinal window (B, white arrows). PCT was evidenced by histopathological examination (C, black arrow). Tumorlets consisted of a comparatively uniform population of cells with oval or spindle nuclei. Mitoses were absent. Immunochemical staining revealed that the neuroendocrine markers CgA (D), Syn (E), CD56 (F), and NSE (G) were highly expressed in the tumorlets.
