Pulmonary tumor embolism from squamous cell carcinoma of the vulva.

Involvement of the pulmonary vessels by tumor emboli has been described from different primary sites of malignancy. A case of pulmonary tumor embolism due to squamous cell carcinoma of the vulva is reported. This form of pulmonary involvement has not previously been described in cases of vulvar carcinoma and it is rare in gynecologic neoplasms. The development of dyspnea with rapid clinical deterioration and fatality associated with multiple pulmonary emboli and histologic signs of pulmonary hypertension is well shown by this case.
