Once the pleural-based lesions have been identified, tissue diagnosis is obtained via image-guided core-needle biopsy or through thoracoscopic biopsy. Benign tumors of the pleura are followed with serial imaging or resected. Parietal pleura has systemic supply, whereas visceral pleura is supplied by pulmonary and bronchial arteries.

This can be demonstrated immunohistochemically with loss lesion brain DICER1 staining in the epithelial cells and normal staining in the malignant mesenchymal cells. Surgeons can remove early-stage or small pleural tumors or cysts with advanced surgical techniques. Fine-needle aspiration takes a small sample from the pleural space, and a core-needle biopsy involves a small incision and X-ray or ultrasound imaging to guide a needle to take a larger tissue sample. The tumors usually present as a localized solid mass, although rare diffuse pleural lesions have been described.
