Mycosis fungoides. Mycosis fungoides, also known as Alibert-Bazin syndrome or granuloma fungoides, [1] 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.
Leukemia cutis. 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.
Frequency. rare. Richter's transformation (RT), also known as Richter's syndrome, is the conversion of chronic lymphocytic leukemia (CLL) or its variant, small lymphocytic lymphoma (SLL), into a new and more aggressively malignant disease. [1] CLL is the circulation of malignant B lymphocytes with or without the infiltration of these cells into ...
Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare hematologic malignancy. It was initially regarded as a form of lymphocyte -derived cutaneous lymphoma and alternatively named CD4+CD56+ hematodermic tumor, blastic NK cell lymphoma, [1] and agranular CD4+ NK cell leukemia. [2] Later, however, the disease was determined to be a ...
Hodgkin lymphoma. Hodgkin lymphoma ( HL) is a type of lymphoma in which cancer originates from a specific type of white blood cell called lymphocytes, where multinucleated Reed–Sternberg cells (RS cells) are present in the patient's lymph nodes. [2] [8] The condition was named after the English physician Thomas Hodgkin, who first described it ...
H&E stain. Cutaneous T-cell lymphoma ( CTCL) is a class of non-Hodgkin lymphoma, which is a type of cancer of the immune system. Unlike most non-Hodgkin lymphomas (which are generally B-cell -related), CTCL is caused by a mutation of T cells. The cancerous T cells in the body initially migrate to the skin, causing various lesions to appear.
Specialty. Oncology, hematology. Adult T-cell leukemia/lymphoma ( ATL or ATLL) is a rare cancer of the immune system's T-cells [1] [2] [3] caused by human T cell leukemia/lymphotropic virus type 1 ( HTLV-1 ). [4] All ATL cells contain integrated HTLV-1 provirus further supporting that causal role of the virus in the cause of the neoplasm. [4]
Tumors of the hematopoietic and lymphoid tissues ( American English) or tumours of the haematopoietic and lymphoid tissues ( British English) are tumors that affect the blood, bone marrow, lymph, and lymphatic system. [1] [2] Because these tissues are all intimately connected through both the circulatory system and the immune system, a disease ...
