Atypical carcinoid tumors grow faster, and they’re more likely to spread, or metastasize, outside of the lungs. Doctors also refer to lung carcinoid tumors based on their location.

Carcinoid tumors have an annual estimated incidence of two to four per 100,000, but the true incidence probably is higher at eight per 100,000 population, as evidenced by autopsy data. Figure 7.

Atypical carcinoid (AC) tumors have a fast growth rate and a higher tendency to spread to other organs. AC tumors are less common than TC tumors and may be more common among individuals who smoke.

Thoracotomy was performed, and the presence of a corticotropin-positive, atypical carcinoid tumor was confirmed. After surgical removal of the tumor, Cushing's syndrome persisted, ...

On the left, four pathology images from a patient with atypical small cell lung cancer show hallmarks of carcinoid cancer in the lungs (thorax), but signs of classical small cell lung cancer where ...

If atypical carcinoid lung tumour has spread to nearby tissues or lymph nodes at the time of diagnosis, prognosis is not very good. As compared with other types of lung cancers, ...
