Management of Diaphragm Tumors

Abstract

Diaphragm tumors are very rare, with secondary tumors being more common than primary tumors. The most common benign primary tumors include lipomas and cysts, and malignant primary tumors include rhabdomyosarcoma and leiomyosarcoma. Endometriosis is the most common benign secondary tumor, followed by malignant tumors with localized spread of disease. In addition, widely metastatic disease has been described. Benign lipomas and cysts can be managed conservatively, but more complex or concerning disease typically requires resection. The diaphragm can often be repaired primarily, though any large defect or tension would indicate the need for mesh or an autologous reconstruction.
