A 74-Year-Old Man with an Enlarging Pleural-Based Mass that was NOT a Mesothelioma

Abstract

Soft tissue sarcomas of the chest wall, also known as primary malignant mesenchymal tumors, may be mistaken for a malignant mesothelioma because of their histologic similarities. Reports of primary pleural sarcomas are exceedingly uncommon. We present an unusual case of a primary pleural sarcoma with unique clinical and histological features not previously seen in any other subtype of pulmonary sarcoma.

Key words

Thoracic surgery - lung neoplasm - cancer - pathology lung
