Which of the following is the most common type of primary carcinoma of the lung in non-smokers?
- A.
  
  Oat cell carcinoma
- B.
  
  Squamous cell carcinoma
- C.
  
  Adenocarcinoma
- D.
  
  Anaplastic carcinoma Anaplastic carcinoma
- E.
  
  Mixed carcinoma
Correct Answer
C. Adenocarcinoma

Explanation
Adenocarcinoma is the most common type of primary carcinoma of the lung in non-smokers. Adenocarcinoma originates in the glandular cells of the lungs and is often found in the outer regions of the lungs. It is more common in women and non-smokers compared to other types of lung cancer. Adenocarcinoma is associated with exposure to certain environmental factors such as secondhand smoke, radon, and asbestos.

A 50 year-old female, non-smoker is found to have a peripheral opacity on a CXR. Which of the following is most likely type of carcinoma?
- A.
  
  Adenocarcinoma
- B.
  
  Carcinoid tumour
- C.
  
  Oat cell carcinoma
- D.
  
  Metastatic tumour
- E.
  
  Mesothelioma
Correct Answer
A. Adenocarcinoma

Explanation
Given that the patient is a 50 year-old female and a non-smoker, the most likely type of carcinoma in this case is adenocarcinoma. Adenocarcinoma is the most common type of lung cancer in non-smokers and is more common in women than in men. It often presents as peripheral opacities on a chest X-ray. Carcinoid tumors, oat cell carcinoma, metastatic tumors, and mesothelioma are less likely in this scenario based on the patient's demographics and clinical presentation.

This is an image of a lung removed from a 45 year-old female smoker. Which of the following is the most likely diagnosis?
- A.
  
  Adenocarcinoma
- B.
  
  Small cell carcinoma
- C.
  
  Squamous cell carcinoma
- D.

- E.
  
  Smoker's lung with pneumonia
Correct Answer
A. Adenocarcinoma

Explanation
The most likely diagnosis for the image of a lung removed from a 45-year-old female smoker would be adenocarcinoma. This is because adenocarcinoma is the most common type of lung cancer in both smokers and non-smokers. It typically originates in the outer areas of the lungs and is associated with the development of tumors in the lung tissue. Given the patient's smoking history and the appearance of the lung in the image, adenocarcinoma would be the most probable diagnosis.

A 37 year-old woman consults her GP with symptoms of a non productive cough, present for approximately 4 months. The GP elicits a further history of loss of appetite and a 6 kg weight loss over the previous 2 months. She does not smoke. On examination, she is afebrile, and there are no remarkable findings. A CXR shows a right peripheral subpleural mass. A fine needle aspiration biopsy is performed and the patient undergoes a right lower lobectomy. The microscopic appearance of the lesion is shown in the below image. What is the most likely diagnosis?
- A.
  
  Adenocarcinoma
- B.
  
  Bronchial carcinoid
- C.
  
  Hamartoma
- D.
  
  Large cell carcinoma
- E.
  
  Bronchoalveolar carcinoma
Correct Answer
A. Adenocarcinoma

Explanation
Based on the given information, the most likely diagnosis for the patient's condition is adenocarcinoma. The patient's symptoms of non-productive cough, loss of appetite, and weight loss, along with the presence of a subpleural mass on the CXR, are consistent with adenocarcinoma of the lung. The microscopic appearance of the lesion would further support this diagnosis. Adenocarcinoma is a common type of lung cancer that arises from the glandular cells in the lining of the lung.
