30-423: The presentation depends if it is mycosis fungoides or Sézary syndrome , the most common, though not the only types. Among the symptoms for the aforementioned types are: enlarged lymph nodes , an enlarged liver and spleen , and non-specific dermatitis . The cause of CTCL remains largely unknown, but several external risk factors have been proposed as potential triggers and promoters of the disease. These include

60-443: A 5-year relative survival rate of 77%, and a 10-year relative survival rate of 69%. After 11 years, the observed relative survival rate remained around 66%. Poorer survival is correlated with advanced age and black race. Superior survival was observed for married women compared with other gender and marital-status groups. The complete remission rate in children is nearly 30%. It is rare for mycosis fungoides to appear before age 20;

90-716: A child's prognosis. Notably, most pediatric persons with MF present with early-stage disease. The criteria for the disease are established on the skin biopsy by the presence of the following: To stage the disease, various tests may be ordered, to assess nodes, blood and internal organs, but most patients present with disease apparently confined to the skin, as patches (flat spots) and plaques (slightly raised or 'wrinkled' spots). Peripheral smear will often show buttock cells . Traditionally, mycosis fungoides has been divided into three stages: premycotic, mycotic and tumorous. The premycotic stage clinically presents as an erythematous (red), itchy, scaly lesion. Microscopic appearance

120-440: A combination of clinical and pathological studies. Diagnosis is sometimes difficult because the early phases of the disease often resemble inflammatory dermatoses (such as eczema , psoriasis , lichenoid dermatoses including lichen planus , vitiligo , and chronic cutaneous lupus erythematosus), as well as other cutaneous lymphomas. Several biopsies are recommended, as the key microscopic features are often absent in early MF, and

150-454: A complete diagnosis requires a combination of clinical and histological study. Furthermore, long periods of treatment can alter the biopsy findings, making it difficult to distinguish from other inflammatory dermatoses. Childhood Mycosis fungoides makes up 0.5% to 7.0% of cases. Although data on childhood MF is limited, a 2021 systematic review observed that there is a significant delay in the diagnosis of childhood MF which may negatively affect

180-422: A greyish or silver appearance. Both patch and plaque stages are considered early-stage mycosis fungoides. The tumour stage typically shows large irregular lumps. Tumours can develop from plaques or normal skin in any region of the body, including the face and head regions. The symptoms displayed are progressive, with early stages consisting of lesions presented as scaly patches. Lesions often initially develop on

210-470: Is a CCR4 monoclonal antibody which has been shown to improve progression-free survival. It was approved by the US FDA in 2018 for use in people with relapsed or refractory mycosis fungoides or Sézary disease . There is no evidence to support the use of acitretin or extracorporeal photopheresis (ECP: a type of phototherapy) for treating people with mycosis fungoides. There is also no evidence to support

240-417: Is caused by abnormal white blood cells ( T-lymphocytes ). These abnormal cells have a preference for localizing and proliferating uncontrolled in the outer layer of the skin ( epidermis ). The abnormal cells may later involve other organs such as the lymph nodes . It is hypothesized that the genetic mutations in these cancer cells lead to increased growth and escape from programmed cell death . Additionally,

270-498: Is highly suggestive of mycosis fungoides. In the tumorous stage a dense infiltrate of medium-sized lymphocytes with cerebriform nuclei expands the dermis. Accurate staging of mycosis fungoides is essential to determine appropriate treatment and prognosis. Staging is based on the tumor, node, metastasis, blood (TNMB) classification proposed by the Mycosis Fungoides Cooperative Group and revised by

300-503: Is needed to identify effective treatment strategies for this disease. Suggested treatments include light therapy, ultraviolet light ( mainly NB-UVB 312 nm ), topical steroids , topical and systemic chemotherapies , local superficial radiotherapy , the histone deacetylase inhibitor vorinostat , total skin electron radiation , photopheresis , systemic therapies (e.g. retinoids , rexinoids), and biological therapies (e.g. interferons ). Treatments are often used in combination. Due to

330-432: Is no cure for CTCL, but there are a variety of treatment options available and some CTCL patients are able to live normal lives with this cancer, although symptoms can be debilitating and painful, even in earlier stages. FDA approved treatments include the following: Histone deacetylase (HDAC) inhibitors are shown to have antiproliferative and cytotoxic properties against CTCL. Other (off label) treatments include: In 2010,

360-425: Is non-diagnostic and represented by chronic nonspecific dermatosis associated with psoriasiform changes in epidermis. In the mycotic stage, infiltrative plaques appear and biopsy shows a polymorphous inflammatory infiltrate in the dermis that contains small numbers of frankly atypical lymphoid cells. These cells may line up individually along the epidermal basal layer. The latter finding if unaccompanied by spongiosis

390-402: Is primarily confined to the skin have a favorable prognosis. People with advanced stage (Stage IIB-IVB) are often refractory to treatment and have an unfavorable prognosis. Treatment options for people with advanced stage disease are designed to reduce tumor burden, delay disease progression, and preserve quality of life. The most commonly recommended first-line treatment for mycosis fungoides

420-444: Is psoralen plus ultraviolet A ( PUVA therapy ). PUVA is a photochemotherapy that involves topical or oral administration of the photosensitizing drug psoralen followed by skin exposure to ultraviolet radiation. Systemic treatments of mycosis fungoides often lead to resistance; as such, additional treatment options are often necessary in advanced disease. Other treatments have been suggested, however, larger and more extensive research

450-401: Is some evidence of a relationship with human T-lymphotropic virus (HTLV) with the adult T-cell leukemia/lymphoma subtype. No definitive link between any viral infection or environmental factor has been definitely shown with other CTCL subtypes. aggressive: Sézary disease Mycosis fungoides Mycosis fungoides , also known as Alibert-Bazin syndrome or granuloma fungoides ,

480-549: Is the most common form of cutaneous T-cell lymphoma . It generally affects the skin, but may progress internally over time. Symptoms include rash, tumors, skin lesions, and itchy skin. While the cause remains unclear, most cases are not hereditary. Most cases are in people over 20 years of age, and it is more common in men than women. Treatment options include sunlight exposure, ultraviolet light , topical corticosteroids , chemotherapy , and radiotherapy . The symptoms of mycosis fungoides are categorized into three clinical stages:

510-513: The International Society for Cutaneous Lymphomas/European Organization of Research and Treatment of Cancer. This staging system examines the extent of skin involvement (T), presence of lymph node (N), visceral disease (M), and presence of Sezary cells in the peripheral blood (B). Most patients with mycosis fungoides have early-stage disease (Stage IA-IIA) at the time of their initial diagnosis. People with early stage disease that

540-476: The U.S. Food and Drug Administration granted orphan drug designation for naloxone lotion as a treatment for pruritus in cutaneous T-cell lymphoma to a pharmaceutical company called Elorac. Of all cancers involving lymphocytes , 2% of cases are cutaneous T cell lymphomas. CTCL is more common in men and in African-American people. The incidence of CTCL in men is 1.6 times higher than in women. There

570-411: The average age of onset is between 45 and 55 years of age for people with patch and plaque disease only, but is over 60 for people who present with tumours , erythroderma (red skin) or a leukemic form ( Sézary syndrome ). Mycosis fungoides is more common in males than in females with differences in incidence across various racial groups reported in different studies. The incidence of mycosis fungoides

600-504: The body) with severe pruritus (itching) and scaling. Itching (pruritus) is the most commonly reported symptom of people experiencing mycosis fungoides with up to 88% of people reporting varying intensities of pruritus that typically worsens as the disease progresses. Those that experience intense pruritus commonly indicate that it negatively affects their quality of life emotionally, functionally and physically. Mycosis fungoides (MF) and Sézary syndrome (SS) are related conditions, with

630-454: The combination treatment of PUVA and intralesional IFN-α or PUVA and bexarotene . Treatment for adults and children with mycosis fungoides often differs because of the safety profiles of modalities. Narrowband UV-B is commonly considered for children, as opposed to Psoralen with UV-A, mechlorethamine hydrochloride , or oral bexarotene , which is often used in adults. A 1999 US-based study of people with CLL's medical records observed

660-413: The condition for four decades. Mycosis fungoides was first described in 1806 by French dermatologist Jean-Louis-Marc Alibert . The name mycosis fungoides is very misleading—it loosely means "mushroom-like fungal disease". The disease, however, is not a fungal infection but rather a type of non-Hodgkin's lymphoma . It was so named because Alibert described the skin tumors of a severe case as having

690-409: The different factors. A point-based algorithm for the diagnosis for early forms of cutaneous T-cell lymphoma was proposed by the International Society for Cutaneous Lymphomas in 2005. Cutaneous T-cell lymphoma may be divided into the several subtypes. Mycosis fungoides is the most common form of CTCL and is responsible for half of all cases. A WHO - EORTC classification has been developed. There

720-456: The disease is an unusual expression of CD4 T cells , a part of the immune system. These T cells are skin-associated, meaning they are biochemically and biologically most related to the skin, in a dynamic manner. Mycosis fungoides is the most common type of cutaneous T-cell lymphoma (CTCL), but there are many other types of CTCL that have nothing to do with mycosis fungoides and these disorders are treated differently. Diagnosis often requires

750-405: The patch stage, the plaque stage, and the tumour stage. The patch stage is defined by flat, reddish patches of varying sizes that may have a wrinkled appearance. They can also look yellowish in people with darker skin. The plaque stage follows the patch stage of mycosis fungoides. It is characterized by the presence of raised lesions that appear reddish-brown; in darker skin tones, plaques may have

780-430: The possible adverse effects of treatment options in early disease it is recommended to begin therapy with topical and skin-directed treatments before progressing to more systemic therapies. In 2010, the U.S. Food and Drug Administration granted orphan drug designation for naloxone lotion, a topical opioid receptor competitive antagonist used as a treatment for pruritus in cutaneous T-cell lymphoma. Mogamulizumab

810-440: The same type of cancer T-lymphocytes, that initially grow in different body compartments. SS cells are found mainly in the blood, whereas MF typically involves the skin. In advanced stages of MF, the cancer cells move from the skin into other organs and the bloodstream; this progression is referred to as "leukemic mycosis fungoides", "Sézary syndrome preceded by mycosis fungoides", or "secondary mycosis fungoides". Mycosis fungoides

840-464: The trunk of the body in places that are rarely exposed to the sun, such as the buttocks. These lesions can start as insignificant patches and may remain undiagnosed for up to a decade. Hypopigmentation (when the skin is lighter than normal) of lesions are less common but can be found in children, adolescents and/or dark-skinned individuals. The advanced stage of mycosis fungoides is characterized by generalized erythroderma (red rash covering most of

870-475: The use of hydrochlorothiazide diuretics, therapy-induced immunosuppression, and possible infections by a range of viral (e.g., HTLV-1 , HTLV-2 , HIV , Epstein-Barr virus , Cytomegalovirus , HHV-6 , HHV-7 , HHV-8 (KSHV) , and Polyomaviruses such as Merkel cell polyomavirus ) and bacterial or fungal pathogens (including Staphylococcus aureus , Mycobacterium leprae , Chlamydophila pneumoniae , and dermatophytes ). The level of evidence varies among

900-431: Was seen to be increasing between 2000 and 2020, although certain regions have demonstrated some stabilization. In 1995 actor Mr. T was diagnosed with a cutaneous T-cell lymphoma, or mycosis fungoides. Once in remission , he joked about the coincidence: "Can you imagine that? Cancer with my name on it — personalized cancer! " Popular British television actor Paul Eddington died of mycosis fungoides after living with
