QuestionChoice
Yes, this is the correct answer. From this patient's signs and symptoms, he is likely to have either lung cancer or tuberculosis. However, the x-ray findings are more suggestive of tuberculosis. Langhans giant cells, which surround caseating granulomas, are common histological findings in patients with tuberculosis.

A 43-year-old man visits the GP with a persistent cough, that occasionally produces bloody sputum. He also has troubling night sweats and has found his clothes are now too big for him. A chest x-ray reveals bilateral upper lobe pulmonary infiltrates.

He is referred for a lung biopsy.

The histological image of a section of this patient's lung is shown below [lightgallery]

Which of the following types of giant cell is seen in this histological image?
