Dermatologic Manifestations of Endocrine Disorders.

Cureus 2021 Sep 27;13(9):e18327. Epub 2021 Sep 27.

Endocrinology, Diabetes and Metabolism, University of Arizona College of Medicine - Phoenix, Phoenix, USA.

Endocrine disorders are known to involve all organ systems of the body, including the skin. The cutaneous manifestations of endocrine disorders can range from common findings such as acanthosis nigricans, pretibial myxedema, acne, hirsutism, hyper or hypopigmentation to rare cutaneous findings such as miliaria rubra, calciphylaxis, lentigines, and calcinosis cutis. These cutaneous symptoms can sometimes be the presenting symptoms or can even be pathognomonic of the underlying endocrine condition. Read More

Obesity-associated lymphedematous mucinosis and stasis mucinosis.

Clin Dermatol 2021 Mar-Apr;39(2):229-232. Epub 2020 Oct 16.

Unit of Dermatology, Department of Medical Science and Public Health, University of Cagliari, Italy.

Cutaneous dermal mucinoses are a group of conditions characterized by abnormal deposition of mucin (hyaluronic acid and sulfated glycosaminoglycans) in the dermis. They can be classified either as localized or generalized forms and occur primarily or secondarily to systemic disorders. Obesity-associated lymphedematous mucinosis and pretibial stasis mucinosis are uncommon and relatively newly recognized disorders occurring in obese patients or in patients with venous insufficiency.

Henoch-Schönlein Purpura (IgA Vasculitis) in Association with Thyrotoxicosis.

Case Rep Endocrinol 2021 22;2021:6669653. Epub 2021 May 22.

Pathology Department, School of Medicine, Kerman University of Medical Sciences, Kerman, Iran.

Graves' disease is the most common cause of hyperthyroidism, which is characterized by thyroid antibodies and the following clinical manifestations: goiter, ophthalmopathy, and pretibial myxedema. On the other hand, Henoch-Schönlein purpura is an IgA-mediated small-vessel vasculitis. Review of the literature showed a relationship between propylthiouracil overdose and the following Henoch-Schönlein purpura (IgA vasculitis) as a side effect. Read More

Local immune microenvironment of skin may play an important role in the development of pretibial myxedema.

Exp Dermatol 2021 12 11;30(12):1820-1824. Epub 2021 Jun 11.

Department of Dermatology, Rui Jin Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, China.

Pretibial myxedema (PTM), characterized by the accumulation of glycosaminoglycans in dermis is an autoimmune skin disorder, which is almost always associated with Graves' disease (GD). Although fibroblast stimulated by thyroid-stimulating hormone receptor (TSHR) antibody, cytokines and growth factors have been postulated as target of the autoimmune process in the dermopathy, the pathogenesis of PTM remains unclear. We hypothesize that the local immune microenvironment of the skin including the antigens and antibodies, T cells, B cells, plasma cells and fibroblasts may play an important role in the development of PTM.

Background: Pretibial myxedema (PTM) is a local mucinous dermopathy associated with thyroid diseases. Since the etiology of PTM is unclear, the aim of this study is to identify the risk factors for PTM and their etiological roles in PTM occurrence.

Methods: A large-scale case-control study (n = 1,200) was performed to identify risk factors for PTM by calculating odds ratio (OR) values and 95% confidential intervals. Read More

BACKGROUND Graves' disease is an autoimmune disease of the thyroid gland and it is considered the most common cause of hyperthyroidism. It is characterized by particular eye manifestations, skin changes, and pretibial myxedema in addition to the signs and symptoms of hyperthyroidism. Graves' disease can be diagnosed based on clinical presentation and low thyroid stimulating hormone (TSH) and elevated free T4 (FT4) levels. Read More

Graves' disease.

Nat Rev Dis Primers 2020 07 2;6(1):52. Epub 2020 Jul 2.

Department of Medicine I, Johannes Gutenberg University Medical Centre, Mainz, Germany.

Graves' disease (GD) is an autoimmune disease that primarily affects the thyroid gland. It is the most common cause of hyperthyroidism and occurs at all ages but especially in women of reproductive age. Graves' hyperthyroidism is caused by autoantibodies to the thyroid-stimulating hormone receptor (TSHR) that act as agonists and induce excessive thyroid hormone secretion, releasing the thyroid gland from pituitary control.

Graves' disease: Clinical manifestations, immune pathogenesis (cytokines and chemokines) and therapy.

Best Pract Res Clin Endocrinol Metab 2020 01 4;34(1):101388. Epub 2020 Feb 4.

Department of Clinical and Experimental Medicine, University of Pisa, Pisa, Italy. Electronic address:

Graves' disease (GD) is characterized by thyrotoxicosis, caused by the presence of circulating thyroid stimulating antibodies (TSAb), that are determinant also in the pathogenesis of its extrathyroidal manifestations [Graves' ophthalmopathy (GO), pretibial myxedema]. T helper (Th)1 immune response prevails in the immune-pathogenesis of GD and GO, during the active phase, when Th1 chemokines, and their (C-X-C)R3 receptor, play a key role. In GD, the existing treatments are not ideal for hyperthyroidism (long-term remission with anti-thyroid-drugs only in 50% of patients; while radioiodine and surgery cause hypothyroidism). Read More

A Case of Unilateral Dermopathy Possibly Related to Graves' Disease.

Eur Thyroid J 2019 Oct 11;8(5):278-282. Epub 2019 Jun 11.

Department of Clinical and Experimental Medicine, Endocrinology Units, University of Pisa and University Hospital of Pisa, Pisa, Italy.

Background: The pathogenesis of the extrathyroidal manifestations of Graves' disease (GD) is not fully clarified. According to the most common hypothesis, they would reflect an autoimmune reaction against antigens constitutively expressed by the thyroid and by the extrathyroidal affected tissues. According to another hypothesis, the so-called Kriss' hypothesis, soluble autoantigens released from the thyroid would reach the affected tissues, where they would become the target of the immune system.
