Question:
Reportability/Histology--Lung: Are adenocarcinoma spectrum lesions on lung imaging reportable when no further information is available? See Discussion.
Discussion:
For example, a chest computed tomography showed multiple subsolid and ground glass pulmonary nodules measuring up to 6 mm; findings favored to reflect adenocarcinoma spectrum lesions. A literature search seems to indicate that adenocarcinoma spectrum lesions include atypical adenomatous hyperplasia through invasive adenocarcinomas.
Answer:
Do not report this case of "adenocarcinoma spectrum lesions" based on the information provided in the absence of a more specific diagnosis. Do not report until/unless a definitive diagnosis of malignancy is made. "Adenocarcinoma spectrum lesion" covers a continuum of lung neoplasms from preinvasive lesions (atypical adenomatous hyperplasia and adenocarcinoma in situ) to invasive lesions (minimally invasive adenocarcinoma and invasive adenocarcinoma).
Should additional information become available, report the case and assign the histology code if a more specific histology is confirmed later. Use text fields to record the details.
