Mesenchymal cystic hamartoma presenting with spontaneous pneumothorax
J Glezos | D Toppin | T Cooney
53-year-old woman presented with a spontaneous right-sided
pneumothorax. Computed tomography chest scan demonstrated
a large bulla involving the right middle lobe. Recurrence
of the pneumothorax after initial closed chest tube
drainage necessitated thoracotomy and wedge resection.
Histopathological examination revealed features consistent
with a benign mesenchymal cystic hamartoma. Pneumothorax
is a recognized complication of mesenchymal cystic hamartoma,
a lesion that also has malignant potential.
