Roentgenological occult large-cell neuroendocrine carcinoma: Report of a long-term survivor

A 64-year-old male patient complained of a one-month history of bloody sputum. A polypoid tumor was almost obstructing the orifice of the subsegmental bronchus (B8b) of the anterior basal segment of the right lower lobe on bronchoscopy. Biopsy specimens of the tumor surface yielded a diagnosis of un...

Sumario:A 64-year-old male patient complained of a one-month history of bloody sputum. A polypoid tumor was almost obstructing the orifice of the subsegmental bronchus (B8b) of the anterior basal segment of the right lower lobe on bronchoscopy. Biopsy specimens of the tumor surface yielded a diagnosis of undifferentiated carcinoma. Clinical staging was T1aN0M0, stage IA. Surgical resection that comprised a right upper lobectomy with systematic mediastinal and hilar lymph node dissection was performed. Histopathologically, the tumor specimen was compatible with large-cell neuroendocrine carcinoma (LCNEC) of the subsegmental bronchus. Pathological staging was T1aN0M0, stage IA. To our knowledge, few cases of central-type LCNEC have been reported in the English literature, and ours is the first report of roentgenological occult LCNEC.
