	'''T-cell prolymphocytic leukemia''' (T-PLL) is a rare and aggressive form of [[leukemia]] that affects the [[T lymphocyte\|T-cells]], a type of [[white blood cell]] that plays a crucial role in the [[immune system]]. This condition is characterized by the proliferation of abnormal T-cells in the [[blood]], [[bone marrow]], and other tissues.

	T-PLL is caused by genetic mutations that lead to the uncontrolled growth of T-cells. These mutations often involve the [[T-cell receptor]] genes and other regulatory genes that control cell growth and apoptosis. The abnormal T-cells in T-PLL are typically larger than normal T-cells and have a distinct appearance under the microscope, known as prolymphocytes.
