| lipid storage diseases | A series of disorders due to inborn errors in lipid metabolism resulting in the abnormal accumulation of lipids in the wrong places (examples include gaucher, fabry and niemann-pick diseases and metachromatic leukodystrophy). (12 Dec 1998) |
| liver diseases, alcoholic | Liver diseases associated with alcoholism. It usually refers to the coexistence of two or more subentities, i.e., alcoholic fatty liver, alcoholic hepatitis, and alcoholic liver cirrhosis, but may be the general entity when subentities are not specified.

| lung diseases, interstitial | A heterogeneous group of noninfectious, nonmalignant disorders of the lower respiratory tract, affecting primarily the alveolar wall structures but also often involving the small airways and blood vessels of the lung parenchyma.

| lymphatic diseases | Diseases of lymph or lymph vessels. (12 Dec 1998) |
| lysosomal diseases | Diseases (also called storage diseases) in which a deficiency of a particular lysosomal enzyme leads to accumulation of the undigested substrate for that enzyme within cells. Not immediately fatal, but within a few years lead to serious neurological and skeletal disorders and eventually to death. See: the following conditions: Hurler sundrome, Hunter syndrome, San Fillipo, Gaucher's disease, Niemann-Pick, Pompe's disease, Tay Sachs disease. (18 Nov 1997) |
| lysosomal storage diseases | Inborn errors of metabolism characterised by defects in specific lysosomal hydrolases and resulting in intracellular accumulation of unmetabolised substrates. (12 Dec 1998) |
| acute reflex bone atrophy | Atrophy of bones, commonly of the carpal or tarsal bones, following a slight injury such as a sprain. See: causalgia, reflex sympathetic dystrophy.

| allogeneic bone marrow transplant | <haematology, procedure> A bone marrow transplant using marrow collected from a matched healthy donor, usually a brother or sister. The risks associated with the transplant increase with age and 50 years of age is generally regarded as the upper limit. (13 Nov 1997) |
