ENKTL may be called ‘extranasal type’ when it affects the skin, testicles, soft tissues, kidneys, brain and/or spinal cord, respiratory tract, gastrointestinal tract, eyes, or adrenal glands. It typically affects areas in the nose (called ‘nasal type’), most often the nasal passages, but it can also affect the upper part of the throat and the paranasal sinuses. It is called ‘extranodal’ because it develops in organs or tissues other than the lymph nodes. Rare, aggressive (fast-growing) cancer that can develop in T lymphocytes (T cells) or in natural killer (NK) cells. Other more general symptoms may be present, such as fevers, low blood counts and weight loss.Įxtranodal natural killer T cell lymphoma (ENKTL), nasal type There may be one or more plaques or nodules, often on the legs. It starts in the fatty layer of the skin, just below the surface. Rare, slow-growing and can occur at any age. Subcutaneous panniculitis-like T cell lymphoma (SPTCL) PCALCL can affect people of all ages, including children, but is most commonly found in adults 45 to 60 years old, and occurs more often in men than women. These lesions may appear anywhere on the body and grow very slowly, so they may be present for a long time before being diagnosed.

PCALCL: An indolent type of CTCL, with characteristic features that include single or multiple raised red skin lesions and nodules, which do not typically crust and have a tendency to ulcerate. LyP can occur at any age and affects both genders equally. LyP is usually classified as non-malignant or as a CTCL precursor. LyP: Presents with self-healing small red-brown bumps and spots on the skin (papules) that come and go. Both disorders can be well-managed and have an excellent prognosis: 1. In both types, a CD30 protein is found on the surface of the abnormal lymphocytes. There are two main types of these disorders, accounting for almost one-third of all diagnosed CTCLs: lymphomatoid papulosis (LyP) and primary cutaneous anaplastic large-cell lymphoma (PCALCL). Primary cutaneous CD30+ lymphoproliferative disorders Other forms of CTCL include: CTCL Subtype Symptoms may be accompanied by changes in nails, hair, or eyelids. Because much heat is lost through the skin, people often feel cold. Oozing of clear fluid from the skin is common. The skin may be hot, sore, extremely itchy, occasionally flaking and burning. SS is the only type of CTCL that always affects the skin and the blood. The malignant (cancerous) T cells found in the skin are also seen circulating in the bloodstream. They may also feel tired, have a fever and have enlarged lymph nodes. People with SS often lose large amounts of skin during the night and may find their bedding covered with skin flakes in the morning. Sézary syndrome (SS): Less common but more aggressive (fast-growing) type of CTCL that is related to MF but presents with very severe itching, total body redness (erythroderma), intense scaling of the skin and frequent hair loss.MF usually occurs in adults over age 50 but affected children have been identified. Advanced stages are defined by involvement of lymph nodes, peripheral blood, and internal organs. Progression from limited skin involvement is variable and may be accompanied by tumor formation, ulceration, and exfoliation, complicated by itching and infections. MF typically presents with red, scaly patches or thickened plaques of skin that often mimic eczema or chronic dermatitis. Most people will have the classic form of MF, but there are several rarer forms. Over time, in about 10% of cases, it can progress beyond the skin. It is an indolent type, following a slow, chronic course, often over many years or decades, and very often does not spread beyond the skin. Classic mycosis fungoides (MF): Most common form of CTCL.chronic) lymphomas – non-curable, but treatable and usually not life-threatening. Skin cancer is the designation for cancers that develop from other, non-lymphoid cells of the skin (epidermal cells, melanocytes, pigment cells). CTCL is sometimes wrongly referred to as a skin cancer because it affects the skin, but this is not a precise use of the term ‘skin cancer’. In CTCL, malignant (cancerous) T-cells travel to the upper layers of the skin, causing a rash, which leads to diagnosis. Cutaneous B-cell lymphomas (CBCLs) more commonly cause lumps in the skin, usually in one or two areas of the body. CTCLs often look red and dry like an eczema rash and can affect widespread parts of the body. Cutaneous T-cell lymphomas (CTCLs) are the most common kind of skin lymphoma. Cutaneous lymphomas are a group of T cell and B cell lymphomas which have a highly variable disease course, clinical presentation, and prognosis.
