Diaphragmatic tumor

Tumor of the diaphragm is rare and less primary. The incidence of benign and malignant tumors is similar. Secondary malignancies can spread directly from tumors in adjacent organs, or they can metastasize to the diaphragm through blood or lymph. Most are metastatic from the lung, esophagus, and stomach, and a few can come from the intestine, reproductive tract, thyroid, and kidney.
