"Lipomatosis conditions"
"Lipomatosis is a condition where there is diffuse excessive fat deposition within the body. Although considered a single entity in the WHO classification of soft tissue and bone tumours 7, lipomatosis encompasses a variety of conditions heterogeneous in demographics, distribution and aetiology. These are, therefore, discussed separately (see below)."
"Importantly many of the conditions that have an abnormal accumulation of fat in certain regions (lipomatosis) can also have a simultaneous loss of fat in other regions (lipodystrophy); HIV-associated lipodystrophy is a good example."
"Occasionally, if extensive, the accumulation of fat can cause mechanical compression and result in regional symptoms which will depend on the location (e.g. nerve root/cauda equina compression or laryngeal compression)."
