Abstract
RATIONALE Hyperpigmentation is a common skin disease. However, there are few reported cases of Grave's disease with diffuse hyperpigmentation. We hereby described a rare case with diffuse hyperpigmentation induced by Grave's disease. PATIENT CONCERNS A 42-year-old Chinese woman with accumulated general pigmentation of skin was admitted to our hospital in October 2017. On examination, hyperpigmentation was observed throughout the whole body, especially on the extremities and the face. DIAGNOSES The patient has elevated levels of serum free thyroxine (FT4), free triiodothyronine (FT3), reduced levels of thyroid-stimulating hormone (TSH) and positive anti-TSH receptor antibody (TRAb). She presented with grade I goiter and a diffusely increased thyroid uptake to 18.5% in thyroid scan. Histopathological examination demonstrated melanin pigmentation in the pigmented skin area. The patient was diagnosed with hyperpigmentation induced by Grave's disease. INTERVENTIONS The patient was treated with oral methimazole (15 mg/day) for thyroid dysfunction and beta blocker for symptom control. OUTCOMES After a period of treatment with methimazole and beta blocker, symptoms of hyperthyroidism ameliorated and hyperpigmentation abated. LESSONS Our studies proposed that in this case the diffuse hyperpigmentation in Grave's disease was caused by elevated adrenocorticotropic hormone (ACTH) as well as anti- TSH receptor stimulating antibody instead of enhanced capillary fragility. Other potential mechanisms for skin pigmentation in hyperthyroidism still need further exploration.

Abstract
BACKGROUND Pemphigus vulgaris (PV) is a potentially fatal autoimmune blistering skin disease. It is known that individuals with autoimmune diseases such as PV, as well as their family members, are at increased risk of developing other autoimmune diseases. However, it is unknown whether there are specific autoimmune diseases that cluster with PV. OBJECTIVES To investigate the frequency of coexisting autoimmune diseases in patients with PV and their relatives, to determine the prevalence of specific autoimmune diseases in patients with PV vs. the general population and to identify statistically significant clinical clusters linking PV with other autoimmune disorders. METHODS We performed a cross-sectional study and meta-analysis of patient data from our own patient database (n = 230), an anonymous online survey conducted by our laboratory (n = 171) and the International Pemphigus & Pemphigoid Foundation registry (n = 393). RESULTS We found that the prevalences of autoimmune thyroid disease (AITD), rheumatoid arthritis and type 1 diabetes were significantly increased in patients with PV compared with the general population. These diseases were also among the most frequent in family members of patients with PV, in addition to systemic lupus erythematosus (SLE). Descriptive cluster analysis using basic principle components methods revealed that PV forms a distinct cluster with AITD, rheumatoid arthritis and type 1 diabetes, and another cluster with SLE, AITD and rheumatoid arthritis. CONCLUSIONS PV belongs to an established autoimmune disease cluster that includes AITD, rheumatoid arthritis and type 1 diabetes. Our data suggest the possibility of common genetic elements across clinically distinct diseases that might underlie autoimmune susceptibility.

Abstract
Background. Thyroid disorders may affect all of the organ systems of the body and they are also highly associated with a wide variety of skin disorders. The aim of this study was to investigate the prevalence of thyroid function abnormalities and thyroid autoimmunity in patients with pemphigus vulgaris (PV) and to determine the association between thyroid disorders and clinical involvement and systemic corticosteroid treatment in patients with PV. Methods. The study consisted of eighty patients with PV and eighty healthy individuals. Thyroid functions (fT3, fT4, and TSH) and thyroid autoimmunity (anti-thyroid peroxidase (anti-TPO), and anti-thyroglobulin (anti-Tg) antibodies) were investigated in both groups. Primary thyroid disease (PTD) was diagnosed with one or more of the following diagnostic criteria: (i) positive antithyroid antibodies, (ii) primary thyroid function abnormalities. Results. Significant changes in the serum thyroid profile were found in 16% (13/80) of the PV group and 5% (4/80) of the control group. Positive titers of antithyroid antibodies (anti-TPO and anti-Tg) were observed in 7 patients (9%) with PV and one in the control group (1,2%). Hashimoto thyroiditis was diagnosed in 9% of PV patients and it was found to be more prevalent in the mucosal form of PV. PTD was found in 13 of (%16) PV patients which was significantly high compared to controls. PTD was not found to be associated with systemic corticosteroid use. Free T3 levels were significantly lower in PV group compared to the control group and free T4 levels were significantly higher in PV group compared to the controls. Conclusions. PV may exist together with autoimmune thyroid diseases especially Hashimoto thyroiditis and primer thyroid diseases. Laboratory work-up for thyroid function tests and thyroid autoantibodies should be performed to determine underlying thyroid diseases in patients with PV.

Abstract
PURPOSE OF REVIEW To review the current understanding regarding thyroid hormone action on skin. To provide a historical context for the recent findings. RECENT FINDINGS Although direct thyroid hormone actions have been demonstrated on multiple aspects of cutaneous biology, rigorous study remains scant. Still, there is a slowly evolving literature supporting the concept that thyroid hormone can directly stimulate epidermis, dermis, and hair. That action may be accessed to treat cutaneous disease. SUMMARY Here, we review the literature regarding thyroid hormone action on skin along with skin manifestations of thyroid disease. We provide context for more recent findings of direct thyroid hormone stimulation of cutaneous cell proliferation in vitro and in vivo which may portend the use of thyroid hormone to treat cutaneous pathologies.

Abstract
Thyroid diseases may be associated with a wide variety of dermatologic disorders. We report a 15-year-old girl with acquired ichthyosis and hypertrichosis associated with hypothyroidism resulting from autoimmune thyroiditis. Her skin lesions progressively resolved after 8 months of replacement therapy with L-thyroxine. This result supports the hypothesis that hypothyroidism in our patient can be directly related to the pathogenesis of acquired ichthyosis and hypertrichosis.

Abstract
Dermatologists may commonly see skin lesions that reflect an underlying endocrine disorder. Identifying the endocrinopathy is very important, so that patients can receive corrective rather than symptomatic treatment. Skin diseases with underlying endocrine pathology include: thyrotoxicosis; hypothyroidism; Cushing syndrome; Addison disease; acromegaly; hyperandrogenism; hypopituitarism; primary hyperparathyroidism; hypoparathyroidism; pseudohypoparathyroidism and manifestations of diabetes mellitus. Thyrotoxicosis may lead to multiple cutaneous manifestations, including hair loss, pretibial myxedema, onycholysis and acropachy. In patients with hypothyroidism, there is hair loss, the skin is cold and pale, with myxedematous changes, mainly in the hands and in the periorbital region. The striking features of Cushing syndrome are centripetal obesity, moon facies, buffalo hump, supraclavicular fat pads, and abdominal striae. In Addison disease, the skin is hyperpigmented, mostly on the face, neck and back of the hands. Virtually all patients with acromegaly have acral and soft tissue overgrowth, with characteristic findings, like macrognathia and enlarged hands and feet. The skin is thickened, and facial features are coarser. Conditions leading to hyperandrogenism in females present as acne, hirsutism and signs of virilization (temporal balding, clitoromegaly).A prominent feature of hypopituitarism is a pallor of the skin with a yellowish tinge. The skin is also thinner, resulting in fine wrinkling around the eyes and mouth, making the patient look older. Primary hyperparathyroidism is rarely associated with pruritus and chronic urticaria. In hypoparathyroidism, the skin is dry, scaly and puffy. Nails become brittle and hair is coarse and sparse. Pseudohypoparathyroidism may have a special somatic phenotype known as Albright osteodystrophy. This consists of short stature, short neck, brachydactyly and subcutaneous calcifications. Some of the cutaneous manifestations of diabetes mellitus include necrobiosis lipoidica diabeticorum, diabetic dermopathy, scleredema adultorum and acanthosis nigricans.

Abstract
Autoimmune thyroid disease (AITD) including Graves' disease, Hashimoto's thyroiditis, and idiopathic hypothyroidism (atrophic Hashimoto's thyroiditis) is of vital concern to the dermatologist. This article reviews the cutaneous manifestations of Graves' disease and Hashimoto's thyroiditis. Recognition of dermatologic manifestations of AITD may alert practitioners to investigate for these disorders. The immune response involved in the pathogenesis of AITD is detailed. Current understanding of the role of genetic and environmental factors, antigens, and apoptosis are elaborated. The future holds exciting insight into the etiology, pathogenesis, and treatment of AITD.

Abstract
Thyroid disorders have a high prevalence in medical practice; they are associated with a wide range of diseases with which they may or may not share etiological factors. One of the organs which best show this wide range of clinical signs is the skin. This review is an attempt to approach most of the dermopathies reflecting several degrees of harmfulness, coming directly or indirectly from thyroid abnormalities, as well as to update current knowledge on the relationship between the thyroid and skin. We have proposed a primary classification of skin disorders, regarding thyroid involvement, into two main groups: 1) dermopathies associated with thyroid abnormalities, mainly with autoimmune thyroid diseases, like melasma, vitiligo, Sjogren's syndrome, alopecia, idiopathic hirsutism, pre-menstrual acne, bullous diseases, connective tissue diseases, hamartoma syndrome, atopy, leprosy and DiGeorge anomaly; and 2) dermopathies depending on the nature of the thyroid disorder, in which the evolution and outcome of the skin disorder depend on the thyroidal treatment in most cases, such as trophism and skin blood flow, myxedema, alopecia, onychodystrophy, hypo- and hyperhidrosis, xanthomas, intraepidermal bullae, carotenodermia, pruritus, flushing, pyodermitis, palmoplantar keratoderma, ecchymosis, etc. In some other cases, the skin disease which developed as a consequence of the thyroid abnormality can remain unaltered despite functional treatment of the thyroid problem, such as pretibial myxedema, thyroid acropachy and some cutaneous manifestations of multiple endocrine neoplasia types 2A and 2B.
