Symptoms include progressive dyspnea, especially on exertion, productive cough; sputum usually thick, chunky, and yellow whitish. fatigability, aching chest pain and weight loss, and occasional cardiovascular failure. Signs include pulmonary rales (rare), finger clubbing (rare), and cyanosis (terminally). Onset at all ages, most often in adult males.
