This "slow" increase, measured
in years.
Retrospective diagnosis case: patient male, 68 years old; Denial of a history of smoking; Family history of the tumor is denied; previous history of tuberculosis, formal treatment; Pigeon breeding hobby
.
Review of chest CT in 2016: fibrous foci
on the upper lobe of the right lung.
Because there is no clear indication of a tumor, the patient is not routinely followed
.
Benign signs of nodules are: long burrs, unclear frosted glass shadow boundaries, and relatively straight
solid component boundaries.
There are few signs of malignancy: bronchiectasis, which can also occur in
old TB foci.
CT in 2022: showed a mixed ground glass shadow of the right upper lung, which was further enlarged
than the former solid composition.
Tumor markers suggest increased CYFRA21-1 and SCC, but these two indicators are of little
significance.
Postoperative pathology: low-differentiation adenocarcinoma, micropapillary, solid, complex acinar subtypes a total of 55%, involving visceral pleural PL2, with STAS, parabronchial lymph node metastasis, pT2N1M0 stage
IIB.
Summary of this example: This example is again verified that slowly increasing ground glass/mixed ground glass nodules within a few years are basically considered adenocarcinoma
.
