Abstract

Familial partial lipodystrophy (FPLD) is a rare, inherited disorder characterised by selective loss of adipose tissue, often affecting the limbs and gluteal region, and concurrent fat accumulation in the face, neck and intra-abdominal areas. This redistribution leads to profound insulin resistance, dyslipidaemia and fatty liver disease. It may be misdiagnosed clinically as type 1 diabetes (T1DM), particularly in patients with lean body habitus, or type 2 diabetes (T2DM) due to insulin resistance. We report a case of a young woman who was initially treated for presumed T1DM but was ultimately diagnosed with FPLD.
