MYELOID LEUKAEMIA

A cross section through the femur from a patient who had myeloid leukaemia, a form of leukaemia with mild to very great splenomegaly and hepatomegaly, and characterised by an uncontrolled proliferation of the myeloid lineage and their precursors in the bone marrow and other sites.

SPLENIC INFARCTION

Splenic infarct is a rare form of pathology. The infarct may be segmental or global, involving the entire organ. It is the result of arterial or venous compromise. Splenic infarct is associated most commonly with hematological disorders.

MONOCYTIC LEUKAEMIA

A blood sample from a patient with monocytic leukaemia. Cells of the myeloid lineage are stained blue. This is a rare acute leukaemia involving monoblasts and monocytes.

CHRONIC LYMPHOCYTIC LEUKAEMIA

A photomicrograph of Chronic lymphocytic leukaemia (CLL), a defect in the body's ability to produce normal white blood cells. These blood cells are produced primarily in the bone marrow. It was discovered that by selectively "destroying" the bone marrow with high doses of chemotherapy and total body irradiation (TBI) and then replacing that destroyed marrow with healthy marrow from a donor, the effects of leukemia could be stopped - and sometimes reversed completely. Transplants where healthy marrow is recieved from a donor are called allogenic transplants.

MYELOID LEUKAEMIA

The enlarged abdomen of a patient with myeloid leukaemia, a form of leukaemia with mild to very great splenomegaly and hepatomegaly, and characterised by an uncontrolled proliferation of the myeloid lineage and their precursors in the bone marrow and other sites.

SKIN RASH IN ACUTE MYELOID LEUKAEMIA

Acute myeloid leukaemia (AML), also called acute granulocytic leukaemia (AGL), acute nonlymphocytic leukaemia (ANLL), acute myelogenous leukaemia, splenomedullary leukaemia or splenomyelogenous leukaemia, is a cancer of blood-forming tissues marked by rapid growth of not-fully-formed granular leukocytes, a type of white blood cell. The symptoms may begin quickly. The typical ones are spongy bleeding gums, iron-poor blood, fatigue, fever, shortness of breath, large spleen, joint and bone pains, and many infections.

ACUTE MYELOID LEUKAEMIA - BONE SPECIMEN

A photograph of a specimen of bone from an acute myeloid leukaemia (AML) patient, showing the bone marrow. AML starts in the bone marrow (the soft inner part of the bones), but in most cases it quickly moves into the blood.

ACUTE MYELOID LEUKAEMIA - BONE SPECIMEN

MYELOID LEUKEMIA

A cancer of blood-forming tissues marked by rapid growth of not-fully-formed granular leukocytes, a type of white blood cell. The symptoms may begin quickly. The typical ones are spongy bleeding gums, iron-poor blood, fatigue, fever, shortness of breath, large spleen, joint and bone pains, and many infections. Greenish tumors (chloromas) may develop in bone or soft tissue. AML may occur at any age, but it usually affects young adults. The diagnosis is made by blood and bone tests. Chemotherapy with various drugs is the main form of treatment.

PROMYELOCYTIC LEUKAEMIA

A photomicrograph showing promyelocytic leukaemia. Acute promyelocytic leukemia (APL) is a subtype of the cancer acute myeloid leukemia (AML). APL is characterised by abnormal, heavily granulated promyelocytes, a form of white blood cells. APL results in the accumulation of these atypical promyelocytes in the bone marrow and peripheral blood, which replace normal blood cells. APL represents about one percent of childhood leukaemia. APL is found more often in children between the ages of two and three, and in adults over 40. However, it has also been found in older children and teenagers. APL is found more frequently in children of hispanic and mediterranean origins.

LM X400 - ACUTE MYELOCYTIC LEUKEMIA

Human cells with acute myelocytic leukemia (AML) in the pericardial fluid, shown with an esterase stain at 400x. Acute myeloid leukaemia (AML) is a rare type of cancer, affecting approximately 2000 adults and less than 100 children per year in the UK. Acute myeloid leukaemia can affect adults of all ages, but is more common in people over 60. Apart from children, AML is rare in people under 20. Leukaemia is a cancer of the white blood cells. Acute myeloid leukaemia is an overproduction of immature myeloid white blood cells.

CHRONIC MYELOID LEUKEMIA

The enlarged spleen from a patient with myeloid leukaemia, a chronic form of leukaemia with mild to very great splenomegaly and hepatomegaly, and characterised by an uncontrolled proliferation of the myeloid lineage and their precursors in the bone marrow and other sites.
