Patient case (clinical description): A 61-year-old man comes to the clinic due to nonproductive cough and progressive dyspnea.  The patient's medical conditions include hypertension, hypercholesteremia and peptic ulcer disease.  He smokes 2 packs of cigarettes daily for the past 30 years.  On examination, there are decreased breath sounds and percussive dullness at the base of the left lung.  Other vital signs are normal. Abdomen is soft without tenderness. CT scan shows a left-sided pleural effusion and nodular thickening of the pleura. The plural fluid was bloody on thoracentesis. Biopsy shows proliferation of epithelioid-type cells with very long microvilli.

Patient's own account: I am 61 and I had to go to the clinic because I couldn't stop coughing and I experienced some breath shortness. I suffer from hypertension and cholesterol and I also have a stomach ulcer. I should admit that I've been smoking 2 packs of cigarettes every day for the past 30 years. My doctor told me that my breath in my left lung sounds bad. But he told me that my blood pressure, heart rate, breathing rate and temperature are normal. My belly is also normal. However my X-Rays show some liquid on the left side and a mass where the liquid got hard. The scary thing is that the liquid was bloody when they got it out. They did a biopsy and it showed that I have an increase of epithelioid-type cells with very long microvilli.
