  • Leukemia, Lymphocytic, Acute, L1: Acute lymphocytic leukemia is a cancer of the white blood cells. Precursors to white blood cells are called blasts and are made by the bone marrow but in ALL the blasts are abnormal and do not develop into lymphocytes. Instead, the abnormal blasts or leukemic cells multiply rapidly and reduce the level of other types of blood cells such as red blood cells and platelets. There are three main subtypes (L1, L2 and L3) which are differentiated by the appearance of the cancerous cells: L1 is characterized by small, uniform cancer cells with a round nucleus and very little cytoplasm. L1 has a better prognosis than L2. L1 is the main form in children (about 85%) but is less common in adults (about 30%).
  • Leukemia, Lymphocytic, Acute, L2: Acute lymphocytic leukemia is a cancer of the white blood cells. Precursors to white blood cells are called blasts and are made by the bone marrow but in ALL the blasts are abnormal and do not develop into lymphocytes. Instead, the abnormal blasts or leukemic cells multiply rapidly and reduce the level of other types of blood cells such as red blood cells and platelets. There are three main subtypes (L1, L2 and L3) which are differentiated by the appearance of the cancerous cells: L2 is characterized by larger cells, an irregular-shaped nucleus, more cytoplasm and significant variation between cells. L2 has a poorer prognosis than L1. L2 is the main form in adults (about 65%) but is less common in children (about 15%).
  • Leukemia, Lymphocytic, Acute, L3: Acute lymphocytic leukemia is a relatively aggressive cancer of the white blood cells. Precursors to white blood cells are called blasts and are made by the bone marrow but in ALL the blasts are abnormal and do not develop into lymphocytes. Instead, the abnormal blasts or leukemic cells multiply rapidly and reduce the level of other types of blood cells such as red blood cells and platelets. There are three main subtypes (L1, L2 and L3) which are differentiated by the appearance of the cancerous cells. L3 is quite uncommon but is very similar to Burkitt's lymphoma - in fact, they may be considered the same disease with different manifestations.
  • Leukemia, Myeloid, Philadelphia-Negative: Acute lymphocytic leukemia is a relatively aggressive cancer of the white blood cells. Precursors to white blood cells are called blasts and are made by the bone marrow but in ALL the blasts are abnormal and do not develop into lymphocytes. Instead, the abnormal blasts or leukemic cells multiply rapidly and reduce the level of other types of blood cells such as red blood cells and platelets. The Philadelphia negative form of the condition is not associated with a genetic mutation. It is distinguished from the positive form by the clinical course which is initially the same but progresses to eventual bone marrow failure without a distinct increase in blast cells. Other differences include poor response to chemotherapy, lower white blood cell counts, greater monocytosis, less basophilia, lower bone marrow myeloid to erythroid ratio and increased likelihood of developing thrombocytopenia. Philadelphia negative patients also tend to be older and median survival rates tend to be poorer.
  • Leukemia, Myeloid, Philadelphia-Positive: Acute lymphocytic leukemia is a relatively aggressive cancer of the white blood cells. Precursors to white blood cells are called blasts and are made by the bone marrow but in ALL the blasts are abnormal and do not develop into lymphocytes. Instead, the abnormal blasts or leukemic cells multiply rapidly and reduce the level of other types of blood cells such as red blood cells and platelets. The Philadelphia form of myeloid leukemia carries the poorest prognosis of all the different types. It involves an acquired genetic mutation which results in the production tyrosine kinase which causes too many white blood cells to be produced which results in a shortage of other blood cell types. Treatment is aimed at inhibiting the production of tyrosine kinase.
  • Leukemia, mast-cell: A very aggressive form of leukemia - a subtype of acute myeloid leukemia. The cancer can in rare cases develop from chronic myeloid leukemia or systemic mastocytosis but generally develops on its own.
  • Leukocytoclastic angiitis - systemic: Inflammation of small blood vessels. Usually the small blood vessels in the ski are involved but sometimes small blood vessels in other organs such as joints, kidneys, and gastrointestinal tract may be involved. Symptoms become more serious once there is systemic (organ) involvement and death may result in some severe cases.
  • Lhermitte-McAlpine syndrome: A type of neurodegenerative disorder that involves pyramidal and extrapyramidal symptoms. It can occur in middle-aged or old people and usually results in death within a year of onset.
  • Liga-induced lead poisoning: Liga is a lead-containing tetraoxide salt used mainly by Mexican people to treat digestive or stomach problems including indigestion and diarrhea. This folk remedy has the potential to cause lead poisoning due to its relatively high content of lead. Children are more susceptible to the effects of lead. The use of folk remedies is still prevalent in some cultures. Lead poisoning can result in serious illness and even death in severe cases.
  • Limbic encephalitis - neuromyotonia - hyperhidrosis - polyneuropathy: A rare autoimmune disorder involving excessive sweating, dysfunction central nervous system and neuromyotonia. The condition occurs when the body develops antibodies to voltage-gated potassium channels.
  • Lion's mane jellyfish poisoning: The Lion's mane jellyfish is a large stinging jellyfish found in the colder waters of the Atlantic, Arctic and Pacific Oceans.
