Abstract

A Solitary Pulmonary Nodule (SPN) is a focal opacity on chest radiographs or CT with a clear border; at least partially covered by lung parenchyma; usually spherical; diameter equal to or less than 3 cm; can be solid (Solid Nodule – SN), Non solid (Ground Glass Opacity – GGO) or Semi-solid (Part Solid – PS). One-third of lung cancers present as solitary masses or nodules and the majority are of the adenocarcinoma type. WHO's updated histopathological classification 2021, Adenocarcinoma is divided into the following types: Minimally Invasive Adenocarcinoma (MIA); Invasive Non-Mucinous Adenocarcinoma (INMA); Invasive Mucinous Adenocarcinoma (IMA); Colloid Adenocarcinoma (CA); Fetal Adenocarcinoma (FA) and Enteric Adenocarcinoma (EA). Minimally invasive adenocarcinoma (MIA) usually has the main characteristic components, in which have Lepidic Predominant Adenocarcinoma (LPA).

We report a case of  LPA, PS type, discovered incidentally, diagnosed and operated at the National Lung Hospital, initially with excellent results.
