Seven cases of subpulmonary pneumothorax are presented: four due to penetrating injury, two to blunt trauma and one to osteosarcoma metastasis. The typical and diagnostic appearance is a basal band of radiolucency bounded above by the thin hair-line of visceral pleura paralleling the dome of the hemi-diaphragm. When partially clotted blood is also present, the appearance becomes less typical and has to be differentiated from traumatic diaphragmatic herniation of bowel and from traumatic pneumatocoele by barium studies and by decubitus radiographs respectively. It is the bridge-like disposition of the pleural cavity between the dome of the hemi-diaphragm and the hollowed concavity of the lung base which allows pneumothorax to collect in it. It is rarely seen because blebs and bullae which are the commonest causes of pneumothorax are most often located in the upper zones.

Spontaneous pneumothorax is an uncommon complication of lung metastatic disease. In most of the cases reported until today, the primary disease was a sarcoma (osteogenic sarcoma, soft tissue sarcoma, hemangioendotheliosarcoma, and Ewing's sarcoma). An exceptional case of spontaneous pneumothorax in a patient suffering from carcinoma of the breast with lung metastases, is herein presented. The pneumothorax developed immediately after regression of lung metastases during administration of combined chemotherapy. Some etiological factors, as well as the rarity of this complication and its treatment, are also discussed.

Of approximately 1,999 cases of osteogenic sarcomas at the Mayo Clinic, 25 were diagnosed as telangiectatic osteogenic sarcomas. Of the 25 patients involved, 16 were males and 9 were females, and their ages ranged from 6 to 49 years. Six patients had had pathologic fracture. The lesions were typically located centrally and usually in the distal femur or proximal humerus and roentgenographically were large and purely lytic with destruction of cortex. Grossly, the lesions were cystic and contained clotted blood. Histologically, cystic spaces that contained blood were lined with anaplastic spindle cells and benign giant cells; sometimes, there were so few malignant cells that diagnosis was difficult. Usually, fine, lacelike osteoid was present. Of the 25 patients, 23 have died of metastatic disease, and another has developed pulmonary metastasis 11 months after amputation. Only one patient has survived for more than five years; however, he has developed pneumothorax. Data from this series suggest that the outlook in telangiectatic osteogenic sarcoma is more bleak than in conventional osteosarcoma.

A 29-year-old patient presented with bilateral pulmonary lesions following surgery for recurrent placental site trophoblastic tumor (PSTT). On day seven after institution of the 'EMA' regimen (etoposide, medium dose methotrexate with folinic acid rescue and actinomycin-D), complete pneumothorax occurred. Closed-system air drainage brought only transient lung expansion and subsequent talc pleurodesis was needed. During follow-up, complete regression of lung metastases was observed. A literature survey of post-chemotherapy pneumothorax in patients with lung metastases disclosed fourteen hitherto reported cases. Including the present PSTT case, non-epithelial gynecologic malignancy (3 patients) ranks second to osteogenic sarcoma (6 cases) with regard to the primary tumor involved.

A report is presented on 5 cases of pneumothorax which occurred during chemotherapy in patients suffering from osteogenic sarcoma of the extremities. None of them presented radiographically detectable substitutive pulmonary lesions. It was hypothesised that the origin of pneumothorax was the necrosis produced by agents of a pulmonary micrometastasis.

Spontaneous pneumothorax is a rare complication in both primary and metastatic pulmonary neoplasms. Occasionally, pneumothorax is associated with chemotherapy of pulmonary malignancies. Pneumothorax after chemotherapy has been reported only in cases with osteogenic sarcoma, synovial sarcoma, fibrosarcoma, germinal tumors, and lymphoma with lung metastasis. We report a case of a patient with malignant thymoma who suffered from lung metastasis after radiation and adjuvant chemotherapy from lung metastasis after radiation and adjuvant chemotherapy (cyclophosphamide, adriamycin, and cis-platinum). A chest X-ray taken 2 days after chemotherapy showed bilateral pneumothorax, which was resolved with conservative treatment. The pneumothorax in this patient is believed to have been caused by the rupturing of the tumor into the pleural cavity and the bronchi.

Seven cases of unilateral, spontaneous pneumothorax were found in a retrospective study of 63 patients with osteogenic sarcoma who were admitted to The Norwegian Radium Hospital (NRH) in the period 1970--1977. The relative risk of pneumothorax developing doubled, from 7--14%, after the introduction of chemotherapy for this disease at NRH. This difference was not statistically significant. Pneumothorax developed in two of 18 patients (11%) with lung metastases who never received chemotherapy. Pneumothorax occurred in four of 19 patients (21%) treated with chemotherapy for manifest lung metastases, and in one of eight patients (13%) who received adjuvant chemotherapy, but in whom lung metastases developed later. Pneumothorax did not develop in 79 patients treated with chemotherapy for disseminated testicular cancer, despite the fact that 82% of these patients had manifest lung metastases.

We describe 12 patients with simultaneous bilateral spontaneous pneumothorax (SBSP). They represent 4 percent of patients with spontaneous pneumothorax seen at our hospital from 1971 to 1990. Five of the 12 had no underlying lung disease. In the seven remaining patients, SBSP was secondary to histiocytosis X, lymphangioleiomyomatosis, osteogenic sarcoma with pleural and pulmonary metastases, Hodgkin's disease, mesothelioma, cystic fibrosis, or miliary tuberculosis. Nineteen of the 56 patients with SBSP (34 percent) described in the literature (this series included) had pulmonary disease related to disorders of cells of mesenchymal origin. Emphysema and bullous lung disease were not associated with SBSP. Long-term prognosis was a function of pulmonary status. Four of the patients described herein died during the period reviewed. All suffered from severe underlying disease. In no case was SBSP the main cause of death. With timely treatment, the short-term prognosis is benign even for patients with underlying lung disease. Surgical pleurectomy should be attempted early, especially in SBSP secondary to underlying lung disease.

An 11-year-old girl with osteosarcoma in the left distal femur, developed unilateral spontaneous pneumothorax. Pneumothorax was found at the initial presentation, but chest CT failed to reveal pulmonary metastases, bullae or blebs.

Secondary spontaneous pneumothorax (SSP) is a rare complication of chemotherapy for pulmonary metastases and to the best of our knowledge, only 28 cases have been described, most of which occurred in patients with osteosarcoma or germ cell tumors. We present herein the case of a 56-year-old woman in whom bilateral and recurrent SSP was caused by the rupture of pulmonary lacunae induced by chemotherapy, given for bilateral lung metastases secondary to breast carcinoma. Our experience of this case led us to conclude that: patients with pulmonary metastases may develop bilateral and/or recurrent pneumothoraces following chemotherapy; computed tomography scan is essential for defining the cause of SSP; and closed chest tube drainage remains the therapy of choice, while chemical pleurodesis may also be used to prevent recidivant SSP.
