Question:
Reportability--Lung: Is carcinoid tumorlet of the lung a reportable disease? See Discussion.
Discussion:
The literature on this is rather ambiguous as to whether these tumorlets (defined as <0.5 cm) are benign, such as atypical hyperplasia, or actual carcinoid tumors.
Answer:
Carcinoid tumorlets are not reportable. The histology can be similar to typical carcinoids; however, they are <5 mm in diameter and are benign/nonreportable.
