Langerhans cell Histiocytosis can present as a single or multiple lesion and can
affect one or several organ systems. A 41-year-old
woman with a
history of multisystemic
Langerhans cell Histiocytosis invading
lung and
thyroid was admitted with left-sided
spontaneous pneumothorax. Here we
report a case of uncommon pulmonary
Langerhans-cell Histiocytosis presenting with
spontaneous pneumothorax as a multisystemic
Langerhans cell Histiocytosis.
