Bilateral spontaneous pneumothorax associated with metastasis of a malignant fibrohistiocytoma.

The case of a 34-year-old female patient is presented. The patient was admitted because of bilateral pneumothorax caused by the metastasis of a malignant histiocytoma originating in the left gluteus. Bilateral chest-suction was made and the patient received complex chemotherapy. The chest X-ray taken 4 months later showed considerable regression of the lymph node metastases. Neither the time of development of pneumothorax nor its mechanism is known. There are only assumptions about it. Authors have considered their case worthy of publication because the lymph node metastasis of bilateral simultaneous pneumothorax due to histiocytoma has not so far been known in the literature.
