Localized malignant lymphohistiocytoid pleural mesothelioma.

We report a case of a 42-year-old man with a right pleural mesothelioma. This neoplasm has 3 rare features. Firstly, it was a localized form: suspected by imaging, visualized by video-assisted thoracoscopy, at the time of the curative-thoracotomy and confirmed by the pathological analysis. The second characteristic is its histological type: "malignant lymphohistiocytoid mesothelioma". This rare subtype has been reported in only 4 papers. Third, after pleuro-pneumonectomy, our patient is alive after 6 years and 5 months postoperatively without any sign of recurrence. Only one case with a long follow-up has been reported but with recurrence at 5 years postoperatively.
