Surgical treatment of synchronous multiple neuroendocrine lung tumours (case series): is more always better?

Pulmonary neuroendocrine lung tumours are uncommon neoplasm; the presence of multiple and synchronous lesions is rare, and few case report are described in the literature. We present a case series of three patients without particular symptom and radiologic finding of multiple synchronous pulmonary nodules. All the patients underwent surgical treatment; histopathologic examination revealed typical carcinoid tumours in all three cases (one patient has a synchronous atypical carcinoid). No oncological progressions were observed at follow-up. A review of current literature is also presented with a suggested strategy management
