A febrile 65-year-old woman who had suffered a new-onset seizure was brought to the emergency department. The patient-a cigarette smoker-was not coughing and had neither chest pain nor a significant medical history. Her temperature was 39.4°C (103°F). She had nuchal rigidity and Kernig's and Brudzinski's signs of meningeal irritation. Lung auscultation revealed signs of right middle lung consolidation. Her white blood cell count was 1,200/µL. A chest film, seen here, showed a masslike density in the right midlung.

A 35-year-old man, a smoker, had right pleuritic pain, productive cough, and fever for 3 days.

A 49-year-old woman, severely obese but otherwise healthy, appeared for a preemployment medical examination. She neither smoked cigarettes nor drank alcohol. She had no respiratory problems and recalled no family history of such. A baseline mammogram taken 4 years earlier showed no abnormalities, and the patient was not under care for any medical condition. Results of physical examination were normal, except for the obesity-which made it difficult to determine breast masses with confidence.

A 52-year-old man from Bangladesh had suffered from pleuritic pain for 1 week. He had never had tuberculosis and-except for being a cigarette smoker-had no notable medical history. The only remarkable findings were a temperature of 37.5°C (99.5°F) and anterior tenderness over the right lower rib cage. Laboratory test results were normal. A tuberculin test with 5 TU of purified protein derivative produced positive results, with a 15 × 17-mm induration.
