Mycosis Fungoides is a rare type of skin lymphoma, which is a cancer that originates in the lymphatic system. It primarily affects the skin, leading to symptoms such as red patches, plaques, or tumors. The condition is a form of cutaneous T-cell lymphoma, where abnormal T-cells accumulate in the skin. The exact cause of Mycosis Fungoides is not well understood, but it typically progresses slowly. Early stages may resemble eczema or psoriasis, making diagnosis challenging. Treatment options include topical therapies, phototherapy, and systemic medications, depending on the severity and progression of the disease.
