Fungating lesion

Type of skin lesion

A fungating lesion is a skin lesion that fungates, that is, becomes like a fungus in its appearance or growth rate. It is marked by ulcerations and necrosis and usually presents a foul odor. This kind of lesion may occur in many types of cancer, including breast cancer, melanoma, and squamous cell carcinoma, and especially in advanced disease. The characteristic malodorous smell is caused by dimethyl trisulfide. It is usually not a fungal infection but rather a neoplastic growth with necrosing portions.
