Lower extremity lipedema, upper extremity lipodystrophy and severe calcinosis complicating juvenile dermatomyositis.
Juvenile dermatomyositis (JDM) is a rare but complex and potentially life-threatening autoimmune disease of childhood. Significant proportions of patients have residual weakness, muscle atrophy, joint contractures, and calcinosis. Recently, new clinical findings, such as lipodystrophy accompanied with increased fat deposition in certain areas, have been reported. So far, it is not known whether the redistribution of body fat may be the type of lipedema of lower extremity. We describe a 39-year-old woman who was diagnosed with JDM at the age of 7. Later she developed symmetrical lipodystrophy of upper extremities and symmetrical lipedema of lower extremities (making 2 and 58.3 % of total body fat mass, respectively), with multiple calcified nodules in the subcutaneous tissues. These nodules gradually increased in size despite therapy. Capillaroscopy findings showed scleroderma-like abnormalities. ANA and anti-U1RNP antibodies were positive. Similar cases with simultaneous occurrence of the lipedema of lower extremities, lipodystrophy of upper extremities, and severe calcinosis complicating JDM have not been published so far. We showed that the calcinosis and lipodystrophy were associated with short duration of active disease. Also, we display case that raises the question whether it is possible overlapping autoimmune diseases revealed during follow-up.
