Prolonged Survival Due to Spontaneous Regression and Surgical Excision of Malignant Mesothelioma

We report a case of malignant pleural mesothelioma with histologically proven spontaneous regression of pleural disease. During a 12-year follow-up there was a single recurrence, which was a lesion in the chest wall at 6 years that was surgically excised. A prominent host response to tumor was seen in both the primary tumor and the recurrence.
