Myxedema - an overview ScienceDirect Topic

  1. In myxedema there is an infiltration with mucopolysaccharides in the subcutaneous tissue. For this reason, this edema is hard, nonpitting, and the indentation of a finger on the skin after pressure does not remain. One manifestation of myxedema—an extreme form of hypothyroidism—occurring in the lower limbs is typical pretibial myxedema

  3. Myxedema, therefore, is to a large extent a lymphatic edema. Hyponatremia is an indirect consequence of the lack of T3 and is directly caused by impaired renal Na reabsorption. Renal Na,K-ATPase is reduced in specific segments. The often discussed role of inappropriate elevation of circulating ADH does not seem to be a key factor in myxedema
  4. Myxedema is the extreme clinical condition in adults where no thyroid hormones are secreted. In these patients, swelling of the skin and subcutaneous tissues is caused by the extracellular accumulation of a high-protein fluid
  5. Pretibial myxedema (PTM) is a rare extrathyroidal manifestation of Graves' disease that requires treatment when the clinical picture is markedly evident. In addition to topical treatment with steroid ointments, there have been previous reports of subcutaneous injections of steroids

Background . Pretibial myxedema (PTM) is a rare dermopathy. The morphologic features and mechanism of its evolving process are not reported in large case series. Methods . 216 cases with PTM were retrospectively reviewed to analyze demographics, history, lesional morphology and its evolving process, histopathology and immunohistochemistry, serum TRAb levels, treatment, and outcome.<i> Results</i> Pretibial myxedema Not technically edema, the swelling on the anterior shins is due to coalescing of subcutaneous plaques due to Graves disease antibodies infiltrating dermal tissue. Patients with edema but no additional symptoms are most likely to have venous stasis or medications.
