Other possible diagnoses include the following:

  • Lymphangioleiomyomatosis (LAM): Patients with pulmonary Langerhans cell histiocytosis X (PLCH) frequently present to medical attention with spontaneous pneumothoraces. Lymphangioleiomyomatosis is a disorder that exclusively affects young women and is characterized by cystic, emphysematous dilation of the terminal airways and shares this predisposition. It may be mistaken for PLCH on a chest radiograph or high-resolution CT (HRCT) scan of the chest.

  • Pulmonary histiocytic sarcoma [11]
