Leukemia cutis is the infiltration of neoplastic leukocytes or their precursors into the skin resulting in clinically identifiable cutaneous lesions. [1] This condition may be contrasted with leukemids , which are skin lesions that occur with leukemia, but which are not related to leukemic cell infiltration.
Subleukemic leukemia, also known as leukemia subleukemic and aleukemic leukemia cutis, is a rare, cancerous blood disease characterized by the presence of abnormal or atypical white blood cells in the peripheral blood while the total white blood cell count is within the normal range. It can also be characterized by leukemic cells in the skin ...
Most patients with mycosis fungoides have early-stage disease (Stage IA-IIA) at the time of their initial diagnosis. [19] People with early stage disease that is primarily confined to the skin have a favorable prognosis. [19] People with advanced stage (Stage IIB-IVB) are often refractory to treatment and have an unfavorable prognosis. [19]
T-cell prolymphocytic leukemia (T-PLL) is a very rare and aggressive leukemia affecting adults; somewhat more men than women are diagnosed with this disease. [24] Despite its overall rarity, it is the most common type of mature T cell leukemia; [ 25 ] nearly all other leukemias involve B cells .
Jessner lymphocytic infiltrate of the skin is a cutaneous condition characterized by a persistent papular and plaque-like skin eruption which can occur on the neck, face and back and may re-occur. This is an uncommon skin disease and is a benign collection of lymph cells. Its cause is not known and can be hereditary.
CLL is the most common type of leukemia in the UK, accounting for 38% of all leukemia cases. Approximately 3,200 people were diagnosed with the disease in 2011. [87] In Western populations, subclinical "disease" can be identified in 3.5% of normal adults, [88] and in up to 8% of individuals over the age of 70. [89]
Blastic plasmacytoid dendritic cell neoplasm is an aggressive malignancy with features of cutaneous lymphoma (e.g. malignant plasmacytoid dendritic cell infiltrations into the skin to form single or multiple lesions) and/or leukemia (i.e. malignant plasmacytoid dendritic cells in blood and bone marrow). [2]
Leukemids, also known as nonspecific cutaneous conditions associated with leukemia, are nonspecific skin lesions that occur with leukemia which are not related to leukemic cell infiltration. [ 1 ] : 745 [ 2 ] This condition may be contrasted with leukemia cutis , which is the infiltration of neoplastic leukocytes or their precursors into the ...
