Match each patient's occupational history and clinical presentation with the most characteristic diagnostic or pathologic finding associated with their exposure.
- A retired naval shipyard worker who develops progressive exertional dyspnea and a chronic dry cough over several months.Bilateral pleural plaques, predominantly in the lower lung zones, and golden-brown fusiform rods on tissue biopsy.
- An individual employed as a monument engraver who reports worsening shortness of breath and fatigue after years of occupational sandblasting.Upper lobe predominant nodular opacities with eggshell calcification of the hilar lymph nodes.
- An aerospace industry technician experiencing progressive dyspnea, joint stiffness, and the appearance of erythematous skin lesions.Widespread noncaseating granulomas on lung biopsy and a positive lymphocyte proliferation test.
- A worker at a battery recycling plant who presents with colicky abdominal pain, memory impairment, and a recent-onset wrist drop.Microcytic hypochromic anemia with coarse basophilic stippling on a peripheral blood smear.
Answer
Shipyard work (asbestos exposure) pairs with lower lobe pleural plaques and ferruginous bodies. Sandblasting (silica exposure) pairs with upper lobe nodules and eggshell calcifications. Aerospace work (beryllium exposure) pairs with noncaseating granulomas. Battery recycling (lead exposure) pairs with basophilic stippling and neuropathy.
Each occupational history provides classic clues for specific exposures. Matching them correctly requires linking the industry (e.g., shipyard for asbestos, sandblasting for silica, aerospace for beryllium, battery recycling for lead) with their pathognomonic diagnostic findings.
