Summary Summary

Mycosis fungoides is a disease in which T-cell lymphocytes (a type of white blood cell) become malignant (cancerous) and affect the skin. This condition is one of the most common types of T-cell lymphoma. Mycosis fungoides is characterized by a scaly, red rash that develops on the skin, particularly on areas that are not usually exposed to the sun. The rash may last for months or years without causing any symptoms. Over time, a thin, reddened, eczema-like rash may develop, followed by thickened, red patches of skin. Finally, tumors form which may develop into ulcers and become infected. Mycosis fungoides is difficult to cure. Treatment is usually palliative, with the intention of relieving symptoms and improving the quality of life.^[1]

Symptoms Symptoms

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Prognosis Prognosis

Mycosis fungoides (MF) has an indolent (low-grade) clinical course, which means that it may persist in one stage, or may slowly progress to another stage (from patches to thicker plaques and eventually to tumors) over years or sometimes decades.^[2] The condition is incurable in most affected individuals, with the exception of those with stage IA disease. The prognosis for each individual varies and is related to the disease stage at the time of diagnosis, the type and extent of skin lesions, and whether the disease is present in other areas of the body (extracutaneous).^[3]
Studies regarding the survival outcomes and prognosis have generally found that:

individuals with stage IA disease at the time od diagnosis who undergo treatment have a normal life expectancy (e.g. that expected based on age, sex and race) -- a 10-year survival rate of 97-98%.
individuals with stage IIB disease with cutaneous tumors have a median survival rate of 3.2 years (a 10-year survival rate of 42%).
those with stage III disease (generalized erythroderma) have a median survival rate of 4-6 years (a 10-year survival rate of 83%).
individuals with extracutaneous stage IVA (lymph nodes) or stage IVB (viscera) disease have a survival rate of less than 1.5 years (a 10-year survival rate of 20% for those with histologically documented lymph node involvement).
individuals with effaced lymph nodes, visceral involvement, and transformation to large T-cell lymphoma have an aggressive clinical course and usually die of systemic involvement or infections.

Other factors that may be associated with reduced survival and increased risk of disease progression include increased age, male sex, and increased lactate dehydrogenase (LDH).^[3]
