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.
