lipoblastic lipoma |
A malignant tumour derived from primitive or embryonal lipoblastic cells. It may be composed of well-differentiated fat cells or may be dedifferentiated: myxoid (liposarcoma, myxoid), round-celled, or pleomorphic, usually in association with a rich network of capillaries.

lipochondrodystrophy |
<syndrome> Mucopolysaccharidosis in which there is a deficiency of alpha-l-iduronidase, an accumulation of an abnormal intracellular material, and excretion of dermatan sulfate and heparan sulfate in the urine; with severe abnormality in development of skeletal cartilage and bone, with dwarfism, kyphosis, deformed limbs, limitation of joint motion, spadelike hand, corneal clouding, hepatosplenomegaly, mental retardation, and gargoyle-like facies; autosomal recessive inheritance. See: mucolipidosis. Synonym: dysostosis multiplex, Hurler's disease, lipochondrodystrophy, Pfaundler-Hurler syndrome, type IH mucopolysaccharidosis. (05 Mar 2000) |

lipochrome |
1. A pigmented lipid, e.g., lutein, carotene. 2. A term sometimes used to designate the wear-and-tear pigments, e.g., lipofuscin, haemofuscin, ceroid. More precisely, lipochrome's are yellow pigments that seem to be identical to carotene and xanthophyll and are frequently found in the serum, skin, adrenal cortex, corpus luteum, and arteriosclerotic plaques, as well as in the liver, spleen, and adipose tissue; lipochrome's do not stain with the ordinary dyes for fat. 3. The pigment produced by certain bacteria. Synonym: chromolipid. Origin: Lipo-+ G. Chroma, colour (05 Mar 2000) |
