C84: Mature T/NK-cell lymphomas
C84.8: Cutaneous T-cell lymphoma, unspecified
Cutaneous T-cell lymphoma, unspecified is a type of non-Hodgkin lymphoma that predominantly affects the skin. This condition involves an uncontrolled growth of T-lymphocytes, a type of white blood cell which plays a role in the immune response. Unlike other types of lymphomas that typically begin in other parts of the body and can subsequently spread to the skin, cutaneous T-cell lymphoma starts in the skin and can potentially progress to internal organs. Early symptoms generally involve patches, plaques, or tumors on the skin that can be itchy or painful. As the disease progresses, symptoms can include enlarged lymph nodes and systemic symptoms like fever, fatigue, or weight loss. The cause of cutaneous T-cell lymphoma is currently unknown and it is not contagious. It is usually diagnosed through skin biopsies and blood tests.
