Review
Monoclonal gammopathy associated with dermatological manifestations are a well-recognized complication. These skin disorders can be associated with infiltration and proliferation of a malignant plasma cells or by a deposition of the monoclonal immunoglobulin in a nonmalignant monoclonal gammopathy. These disorders include POEMS syndrome, light chain amyloidosis, Schnitzler syndrome, scleromyxedema and TEMPI syndrome. This article provides a review of clinical manifestations, diagnostics criteria, natural evolution, pathogenesis, and treatment of these cutaneous manifestations.

Review
Stem cells are precursor cells present in many tissues with ability to differentiate into various types of cells. This interesting property of plasticity can have therapeutic implications and there has been substantial research in this field in last few decades. As a result, stem cell therapy is now used as a therapeutic modality in many conditions, and has made its way in dermatology too. Stem cells can be classified on the basis of their source and differentiating capacity. In skin, they are present in the inter-follicular epidermis, hair follicle, dermis and adipose tissue, which help in maintaining normal skin homeostasis and repair and regeneration during injury. In view of their unique properties, they have been employed in treatment of several dermatoses including systemic sclerosis, systemic lupus erythematosus, scleromyxedema, alopecia, Merkel cell carcinoma, pemphigus vulgaris, psoriasis, wound healing, epidermolysis bullosa and even aesthetic medicine, with variable success. The advent of stem cell therapy has undoubtedly brought us closer to curative treatment of disorders previously considered untreatable. Nevertheless, there are multiple lacunae which need to be addressed including ideal patient selection, timing of intervention, appropriate conditioning regimens, post-intervention care and cost effectiveness. Further research in these aspects would help optimize the results of stem cell therapy.

Review
Scleroderma is divided into a systemic form called systemic sclerosis and a localized form also called morphea. According to 2013 ACR/EULAR Classification Criteria for Systemic Sclerosis, developed by the American College of Rheumatology (ACR) and the European League Against Rheumatism (EULAR), skin thickening of the fingers extending proximal to the metacarpophalangeal joints is sufficient for a patient to be classified as having scleroderma. Histological examination is not included in the diagnostic criteria and is not routinely performed. Skin biopsy is recommended only in the case of diagnostic doubt with other scleroderma like disorders (scleromyxedema, scleredema, nephrogenic systemic fibrosis). Alternatively, skin biopsy is also often performed for research purposes. Indeed, the first step analysis of new cytokines or pathways that may contribute to the pathogenesis of the disease requires the evaluation of their expression or activation in the skin of scleroderma patients compared to healthy controls. The histological picture of the skin in bot localized and systemic scleroder shows initially microvascular alterations and chronic inflammation while in the more advanced stages skin fibrosis prevails. Localized scleroderma (LS) or morphea includes a number of subtypes which are classified more according to their clinical presentation rather than histopathological pictures. However, some histopathologic changes may be useful in differentiating each entity from the others and from other sclerodermoid disorders.

Scleromyxedema is a rare, cutaneous deposition disorder from the group of mucinoses, which can affect multiple organs and is virtually always associated with a monoclonal gammopathy. Cutaneous manifestations are usually generalized, 2 to 3 mm sized, dome-shaped or flat-topped, waxy, slightly red to skin-colored papules and sclerodermoid indurations. Neurological, rheumatological, cardiovascular, gastrointestinal, respiratory tract, renal and ophthalmologic manifestations can occur, with decreasing frequency. A serious and potentially lethal complication is the dermato-neuro syndrome which manifests with flu-like prodromes followed by fever, convulsions and coma. Untreated, scleromyxedema usually takes an unpredictable and potentially lethal progressive disease course over several years. According to a widely acknowledged classification by Rongioletti a diagnosis of scleromyxedema can be rendered when (1) generalized, papular and sclerodermoid eruption, (2) a histological triad of mucin deposition, fibroblast proliferation and fibrosis, and (3) monoclonal gammopathy are present, and (4) thyroid disease is absent. Apart from the classic microscopic triad, an interstitial granuloma annulare like pattern was also described. The pathogenesis of scleromyxedema is unknown. A potential role for various, as yet unknown serum factors has been discussed. An unequivocal causal relationship between paraproteinemia and disease manifestations could not be established to date. High dose intravenous immunoglobulins (IVIg) are the first-line treatment of choice according to the most recent European guidelines.

Review
Scleroderma refers to an autoimmune connective tissue fibrosing disease, including three different subsets: localized scleroderma, limited cutaneous systemic sclerosis, and diffuse cutaneous systemic sclerosis with divergent patterns of organ involvement, autoantibody profiles, management, and prognostic implications. Although systemic sclerosis is considered the disease prototype that causes cutaneous sclerosis, there are many other conditions that can mimic and be confused with SSc. They can be classified into immune-mediated/inflammatory, immune-mediated/inflammatory with abnormal deposit (mucinoses), genetic, drug-induced and toxic, metabolic, panniculitis/vascular, and (para)neoplastic disorders according to clinico-pathological and pathogenetic correlations. This article reviews the clinical presentation with emphasis on cutaneous disease, etiopathogenesis, diagnosis, and treatment options available for the different forms of scleroderma firstly and for scleroderma-like disorders, including scleromyxedema, scleredema, nephrogenic systemic fibrosis, eosinophilic fasciitis, chronic graft-versus-host disease, porphyria cutanea tarda, diabetic stiff-hand syndrome (diabetic cheiroartropathy), and other minor forms. This latter group of conditions, termed also scleroderma mimics, sclerodermiform diseases, or pseudosclerodermas, shares the common thread of skin thickening but presents with distinct cutaneous manifestations, skin histology, and systemic implications or disease associations, differentiating each entity from the others and from scleroderma. The lack of Raynaud's phenomenon, capillaroscopic abnormalities, or scleroderma-specific autoantibodies is also important diagnostic clues. As cutaneous involvement is the earliest, most frequent and characteristic manifestation of scleroderma and sclerodermoid disorders, dermatologists are often the first-line doctors who must be able to promptly recognize skin symptoms to provide the affected patient a correct diagnosis and appropriate management.

PURPOSE OF REVIEW
To synthesize the current known data on pathogenesis and treatment of scleromyxedema. This review will also highlight the clinical presentation, systemic features and outcomes and distinguishing features between scleromyxedema and scleroderma, as a common mimic.
RECENT FINDINGS
Most recent publications have focused on describing treatment responses with novel therapies, with the majority of cases reporting success with intravenous immunoglobulin. However, other therapies suggest promise as well in case reports, including bortezomib, thalidomide and stem cell transplantation. There is little information on pathogenesis; however, focus has been on the relationship between the mucin deposition and the monoclonal immunoglobulins that are seen in almost all patients with scleromyxedema.
SUMMARY
Scleromyxedema is a rare mucinous deposition disorder that shares clinical features with scleroderma but has important distinguishing features in clinical presentation and major organ complications that should be recognized. Patients typically respond well to therapy as highlighted in several larger series, but poor outcomes are reported in a few cases.

Review
BACKGROUND
Scleroderma is a term used to describe diseases that involve hardening and tightening of the skin and the underlying subcutaneous connective tissue. It could be localized to skin and subcutaneous tissue, or may involve the internal organs too in systemic sclerosis.
OBJECTIVE
There are disorders that can cause hardening and tightening of skin and mimic scleroderma but are rarely associated with Raynaud phenomenon, sclerodactyly, and autoantibodies in the serum, features specific to scleroderma/systemic sclerosis.
CONCLUSION
These are termed as "scleroderma variants" or "scleroderma like disorders". This review discusses the various "scleroderma variants" e.g. scleromyxedema, scleredema, nephrogenic systemic fibrosis, and eosinophilic fasciitis.

Review
Scleromyxedema is a rare disorder that frequently affects multiple extracutaneous organ systems and is usually associated with monoclonal gammopathy. The pathogenesis of scleromyxedema is unknown. The clinical course is chronic and progressive and can lead to marked morbidity or death. The skin findings consist of multiple waxy papules and indurated plaques. Progressive skin involvement can lead to decreased mobility of the mouth and joints. Extracutaneous manifestations occur in the musculoskeletal or cardiovascular system, in the gastrointestinal or respiratory tract, or in the kidneys. There are no approved or evidence-based treatment options available for scleromyxedema. High-dose immunoglobulins are considered the treatment of choice, followed by lenalidomide (or thalidomide) and systemic glucocorticosteroids, or in severe cases even autologous hematopoetic stem cell transplantation. Long-term maintenance treatment is usually required and close clinical follow-up is necessary as recurrence of scleromyxedema is common after withdrawal of an effective therapy.

Review
Scleromyxedema is a chronic, idiopathic disorder associated with monoclonal gammopathy, and characterized by dermal mucin deposition. However, systemic manifestations are frequent, including neuromuscular symptoms. We herein present a 71-year-old man who developed a vacuolar myopathy in a context of a known scleromyxedema, and we compare our observation with the nineteen other cases found in the medical literature. Such an association (especially with suggestive skin abnormalities) has to be known for two reasons. First, this diagnosis might be quite challenging because the myopathy may precede the typical skin changes. Secondly, conversely to other forms of vacuolar myopathy, some of the symptoms may respond (even partially) to immunomodulatory and/or immunosuppressant therapeutics.
