Localized myxedema is most commonly described in patients with hyperthyroidism, especially Graves' disease. Although pretibial myxedema generally appears as indurated plaques on the shins, it has also been rarely reported in other areas such as the face, shoulders, arms, and abdomen. We report a rare case of preradial myxedema in a hyperthyroid patient who was taking thyroxine post thyroidectomy for goiter. Read More

Pretibial myxedema or thyroid dermopathy constitutes dermal deposition of mucin, primarily hyaluronic acid and chondroitin sulfate. It is a manifestation of autoimmune thyroiditis, seen more in Graves disease than in Hashimoto thyroiditis. The time delay from treatment of hyperthyroidism to appearance of localized myxedema varies from one month to 16 years (mean 5. Read More

Background: Severe pretibial myxedema (PTM) can be difficult to manage, highlighting the need to investigate newer therapies. Rituximab (RTX) and intravenous immunoglobulin (IVIg) have been tried in Graves' orbitopathy. Since PTM and orbitopathy share a similar underlying pathophysiology, this study aimed to explore these therapies for progressive PTM. Read More

Intravenous immunoglobulins (IVIG) are therapeutic products, comprising polyclonal IgGs, which are obtained from human plasma pool of healthy blood donors. Despite the lack of Food and Drug Administration (FDA) approval, the experience of using IVIG in various dermatological diseases increases day by day and exciting results are reported. However, experience with the use of IVIG in dermatological indications are mostly case reports whereas randomized, controlled, double-blind, multicentric studies have not been performed. Read More

Pretibial myxedema (PTM), an uncommon manifestation of Graves' disease (GD), is a local autoimmune reaction in the cutaneous tissue. The treatment of PTM is a clinical challenge. We herein report on a patient with PTM who achieved complete remission by multipoint subcutaneous injections of a long-acting glucocorticoid and topical glucocorticoid ointment application for a self-controlled study.

The extrathyroid manifestations of Graves disease (GD) include thyroid orbitopathy, dermopathy, and acropachy. Thyroid dermopathy (TD), also known as pretibial myxedema, classically presents as nonpitting edema or plaquelike lesions on the pretibial region, while thyroid acropachy (TA) is seen in cases of severe TD, characterized by soft tissue swelling and clubbing of fingers and toes, as well as a periosteal reaction of the bones of the hands and feet. Both TD and TA are rare manifestations of thyroid disease and uncommonly reported in pediatric patients. Read More

Pretibial myxedema (PM) is a rare extrathyroidal manifestation of Graves' disease (GD), usually during the hyperthyroid state, coexisting with orbitopathy. We describe a rare case of a biopsy-proven PM in a euthyroid patient, without history of GD or Hashimoto's thyroiditis. Assessment of commonly reported thyroid autoantibodies, such as thyroid peroxidase and thyroglobulin autoantibodies, thyroid stimulating immunoglobulins and thyroid binding inhibitory immunoglobulins, was negative.

Purpose: Thyroid autoimmunity affects approximately 5% of the population, and its investigation relies heavily on the use of autoantibodies. Thyroid stimulating hormone receptor (TSHR) autoantibodies (TRAb) play a central role in the evaluation of Graves disease (GD), Graves ophthalmopathy (GO) and pretibial myxedema (PTM). However, there is still controversy regarding overall TRAb assay diagnostic accuracy and their prognostic utility. Read More

Objective: Local immune regulation therapy has been one of the therapeutic methods used for the treatment of autoimmune thyroid disease in patients with pretibial myxedema (PTM). However, the poor response rate and high recurrence rate are still major problems. Whether a premixed corticosteroid, compound betamethasone, could enhance remission rate and decrease recurrence rate in patients with PTM was investigated in the present study. Read More

Graves' disease is an autoimmune disease, which can manifest with a variety of extrathyroidal clinical syndromes like ophthalmopathy, pretibial myxedema (dermopathy), acropathy, cardiomyopathy, and encephalopathy. Though quite rare, this disease can also manifest with gastrointestinal symptoms such as dysphagia, heartburn, nausea, vomiting and diarrhea. We report a clinical case of Graves' disease manifesting with dysfunction of the esophagus and heartburn in a 61-year-old man. Read More

The pretibial myxedema is a manifestation of Graves' disease characterized by accumulation of glycosaminoglycans in the reticular dermis. The dermopathy is self-limiting but in some cases may cause cosmetic and functional damage. Conventional treatment is use of topical steroids under occlusive dressing, however the intralesional application has shown good results. Read More

Pretibial myxedema (PM) is a rare autoimmune manifestation of Graves' disease, which commonly presents as diffuse, nonpitting edema of shins and less often as plaques, nodules, or elephantiasis lesions mimicking lymphedema. We present a 57-year-old woman with 12-month history of PM, which occurred a year after treatment of Graves' disease and improved with topical corticosteroids, support stockings, and intralesional steroid injections until recurrence with local erythema and woody edema. A literature review was undertaken of the evidence-based treatment modalities for symptomatic PM: although commonly asymptomatic and self-limited, severe cases of PM may be treated with topical corticosteroid, compressive therapy, and intralesional corticosteroid injections.

Localized or pretibial myxedema is one of the signs of Graves disease (along with goiter, exophthalmus, thyroid acropathy, and high circulating levels of long-acting thyroid-stimulating hormone) and usually tends to occur at a later stage of the disease or even after the patient becomes euthyroid post treatment. Very rarely has it been reported in euthyroid patients. We report a euthyroid man presenting with localized myxedema on the extensor surface of his forearm with clinical and histopathological features consistent with pretibial myxedema. Read More
