The most common type of blood cancer is developed in the white blood cells called lymphocytes and is known as lymphoma. It can be classified as either Hodgkin’s lymphoma or non-Hodgkin’s lymphoma, according to its characteristics. It can appear in different parts of the body, including the skin. Cutaneous lymphoma is a subtype of non-Hodgkin’s lymphoma and can originate in both B-cells and T-cells.
The lymphocytes are responsible for protecting the body against infections, but these cells reproduce and expand uncontrollably in lymphoma patients. The cells affected by the cancer travel to different parts of the body, forming a mass or tumor in locations such as the lymph nodes. Cutaneous lymphoma can involve not only the skin, but also the blood, lymph nodes, and internal organs.
