A pulmonary carcinoid tumorlet (PCT) is a nodular proliferation of neuroendocrine cells smaller than 0.5 cm. On computed tomographic (CT) imaging, these nodules are nonspecific in appearance and can mimic metastatic disease. Cases of multiple PCTs diagnosed between 1992 and 2003 in patients with ...

[4] in 1944, it was not until 1972 that histologic criteria for separating these tumors were proposed by Arrigoni et al.[5] In the intervening 25 years, numerous studies have continued to confirm that there is a spectrum of neuroendocrine-appearing tumors from the carcinoid tumorlet to small...
44, 45 Hence, only diffuse idiopathic neuroendocrine cell hyperplasia, a generalized proliferation of pulmonary neuroendocrine cells that includes tumorlet formation, is recognized as a preinvasive condition of carcinoids development in the WHO classification of lung tumors.42, 45 Interestingly, the or...
