Mass on upper chest

A 60-year-old woman asked her family physician (FP) to look at the solid, nontender, movable mass on her upper chest that had been there for 6 months. She had lost 10 pounds over the last year without dieting and her “smoker’s cough” (she smoked a pack of cigarettes a day since age 18) had recently gotten worse. She now occasionally coughed up blood-tinged sputum. The FP excised the mass and sent it to Pathology.

What's your diagnosis?


 

The pathology report indicated that the patient had squamous cell carcinoma (SCC) of the lung, a diagnosis that was consistent with an x-ray and computed tomography (CT) scan that were also done.

Lung cancer is a malignant neoplasm of the lung arising from the respiratory epithelium (bronchi, bronchioles/alveoli). The 4 major cell types responsible for 88% of cases are:

○ adenocarcinoma (including bronchoalveolar)—32% of cases

○ squamous cell carcinoma—29% of cases

○ small cell (or oat cell) carcinoma—18% of cases

○ large cell (or large cell anaplastic)—9% of cases.

Smoking is the major risk factor for lung cancer; a smoking history (current or former) is present in 90% of cases, with a risk ratio (RR) of 13 (passive smoke exposure has a RR of 1.5). Skin nodules from lung cancer metastases may not be painful but are a poor prognostic sign.

Any time spent helping your patients quit smoking may help avert a fatal outcome. In this case, the patient opted not to receive treatment. She passed away 10 months later.
