There was one question from Semester 3 exam that I still remember until today. The question asks to describe 'honeycomb lung'. Most of us could not remember learning about 'honeycomb lung'. Apparently the answer was based on 2-3 slides and we need to listen to the explanation given by the lecturer. The question worth 10 marks and I tried my best to answer the question even though I hardly remember anything from the lecture.
My current rotation which is heart and lung reminds me of this unanswered question.
There are many lung diseases that will eventually end up in the same appearance during post-mortem. Honeycomb lung refers to the end stage of various diseases. There is even mnemonic for this term.
Occupational disease (pneumoconiosis, farmer's lung)
COllagen vascular disease
This is how honeycomb lung looks like. Pathologist ie the doctors that look cells under the microscope and do post-mortem have a tendency to associate food with dead human tissues.
