Answer

Patients with pulmonary Langerhans cell histiocytosis X (PLCH) present with nonspecific physical findings. Neither inspiratory rales (crackles) nor clubbing is common. Cor pulmonale may develop; therefore, the following related findings may be present:

  • Loud second heart sound with accentuated pulmonic component

  • Tricuspid regurgitation murmur

  • Right ventricular lift

  • Peripheral edema
