 Definition of MFW. Malignant Fungating wounds arise as a result of infiltration of the structures of the skin by malignant cells. These cells may arise from primary skin cancer, an underlying malignant tumor or through metastasis spread from a distant malignant tumorPunder, 1998.A fungating cancer is a primary or secondary malignant growth in the skin which has ulcerated and results in pain, exudates, bleeding, infection and malodourTwycross, 1995 .A malignant tumor will invade and destroy adjacent tissues and can spread to other tissues with in cells that break off and travel in the blood or lymph system. It can develop its own blood supply, sometime outgrowing it and causing the tumor to become necrotic in the middleMera, 1997.Dealey1994 states that, as the tumor extends, capillaries rupture, leading to epithelium results in ulceration through the skin, and lesions presents as a fungating, foul-smelling massDaeley, 1994.Fungating malignant wounds are caused by the infiltration of the skin and its supporting blood and lymph vessels by a local tumor or as a result of metastasis growth from the primary tumor. Unless the malignant cells are checked by single or combination cancer treatments the fungation extends with the potential for causing massive damage at the wound site through a combination of proliferate growth, loss of vascularity and ulcerationMortimer, 1998 .A fungating wound is defined as a cancerous lesion involving the skin, which is open and may be draining. The lesion may be result of a primary cancer or metastasis to the skin from a local tumor or from a tumor in a distant site. It may take the form of a cavity, an open area on the surface of the skin, skin nodules, or a nodular growth extending from the surface of the skinBritish Columbia Cancer Agency, 2001 .As the malignant cells multiply in the skin they form a tumour that enlarges causing disruption of skin capillaries and lymph vessels, eventually leading to tissues Hypoxia and subsequent skin necrosis.
