AI Article Synopsis
- A 57-year-old man showed a concerning mass on a chest x-ray, which grew larger over the course of a year.
- A lung cancer suspicion was raised following a PET scan, leading to surgery (lingular segmentectomy).
- The final diagnosis revealed the mass to be pulmonary actinomycosis instead of cancer, highlighting the importance of considering this condition as a possible lung cancer alternative.
Article Abstract
A 57-year-old man had been observed a mass-like shadow on a chest radiograph. One year later, chest computed tomography (CT) revealed the enlargement of the shadow. Positive finding of fluorodeoxyglucose-positron emission tomography (FDG-PET) suspected lung cancer, and lingular segmentectomy was performed. The pathological diagnosis was pulmonary actinomycosis. It is necessary to consider pulmonary actinomycosis is a differential diagnosis of lung cancer.

KRAS is a proto-oncogene that is found to be mutated in 15% of all metastatic cancers with high prevalence in pancreatic, lung, and colorectal cancers. Additionally, patients harboring KRAS mutations respond poorly to standard cancer therapy. As a result, KRAS is seen as an attractive target for targeted anticancer therapy.

Early cancer detection substantially improves the rate of patient survival; however, conventional screening methods are directed at single anatomical sites and focus primarily on a limited number of cancers, such as gastric, colorectal, lung, breast, and cervical cancer. Additionally, several cancers are inadequately screened, hindering early detection of 45.5% cases.
