lichen myxedematosus

Scleromyxedema (SM) was previously known to be associated with monoclonal gammopathy. The association of SM and its counterpart lichen myxedematosus (LM) with chronic hepatitis has rarely been reported. We retrospectively reviewed medical records and histopathological reports of consecutive patients who presented at our department with the diagnosis of SM or LM from January 2001 to September 2017. The patients' demographic details, cutaneous presentation, associated underlying diseases and hepatitic profile were studied and compared with previous published cases...

Reticular erythematous mucinosis (REM) is a rare form of primary cutaneous mucinosis, most often involving the midline of the upper chest or back in middle-aged women. REM bears clinical and histopathologic resemblance to lupus erythematosus tumidus (LET), dermatomyositis, scleredema, and lichen myxedematosus. Early recognition and diagnosis of REM is particularly relevant to exclude the abovementioned diseases, as REM is more benign and has fewer systemic consequences.

Scleromyxedema and lichen myxedematosus (LM) are rare disorders that fall along the spectrum of primary cutaneous mucinoses. Scleromyxedema is a systemic form that classically presents with generalized waxy papules, sclerodermoid eruption, and monoclonal gammopathy; LM is a localized form limited to the skin that classically presents with white, firm, waxy papules and lacks monoclonal gammopathy. According to diagnostic criteria established in 2001, the diagnosis of both conditions requires absence of thyroid disease...

BACKGROUND: Scleromyxedema, also referred to as the Arndt-Gottron (S-AG) syndrome or the systemic form of Lichen myxedematosus (LM), is a cutaneous mucinosis with a chronic course and high lethality from systemic involvement of other organs and systems. Interesting in several aspects is the association between scleromyxedema and viral hepatitis about: 1) hepatitis virus infection as a possible etiological factor for the development of scleromyxedema, 2) antiretroviral therapy for the treatment of hepatitis as a method of reversing scleromyxedema and 3) antiviral drugs as inducers of scleromyxedema...

Lichen myxedematosus is a chronic cutaneous mucinosis that can present on a spectrum from localized cutaneous lesions to systemic disease of scleromyxedema. The clinical presentation of localized cutaneous lichen myxedematosus is waxy lichenoid papules, nodules, and/or plaques that have histopathologic findings of mucin deposition and a variable degree of fibroblast proliferation. There is an absence of serum paraproteins, and there are no other systemic causes of cutaneous mucinosis such as thyroid disease...

INTRODUCTION: Secondary lymphedema is the most frequent long-term complication of axillary lymphadenectomy. It can result in complication as erysipelas, warts, Papilloma Cutis Lymphostatica (PCL), or angiosarcomas. Moreover, in women affected by breast cancer an accurate differential diagnosis among these conditions or complication related to radiation dermatitis or cutaneous metastasis is essential. PRESENTATION OF CASE: We report the case of a 60-year-old postmenopausal Caucasian woman affected by secondary lymphedema following complete mastectomy for breast cancer...

Scleromyxedema is regarded as a rare cutaneous mucinosis from a group of lichen myxedematosus characterized by diffuse mucin deposition, sclerosis, and lichenoid eruptions in the absence of thyroid disease. The paper discusses the pathogenesis of the disease and histological changes in tissues. It underlines the need for using histochemical tests to identify acidic and neutral glycosaminoglycans and gives a differential diagnosis of this disease.

Lichen myxedematosus is condition characterized by localized areas of dermal deposition of mucin, presenting with firm papules localized to few areas of the body. The condition needs to be excluded from scleromyxedema, which, in addition to the firm papular eruption, has areas of induration and is usually associated with a monoclonal gammopathyand systemic symptoms. We present a 62-year-old woman with a several-year history of asymptomatic, firm papules over the face and arms with no evidence of thyroid disease or a monoclonal gammopathy,which is consistent with a diagnosis of localized lichen myxedematosus, the discrete papular variant...

Lichen myxedematosus is an idiopathic, cutaneous mucinosis with 2 clinicopathologic subsets. There is the generalised papular and sclerodermoid form, more properly termed scleromyxedema, and the localised papular form. We report the first case, to our knowledge, of lichen myxedematosus in association with rheumatoid arthritis as well as a case in association with dermatomyositis. An up-to-date literature review on cutaneous mucinoses and connective tissue diseases, excluding the common association of primary and secondary mucinoses with systemic lupus erythematosus, was also performed...

A 41-year-old man was referred to our outpatient department with a diagnosis of urticaria with angioedema of 3 months duration. On examination, he had generalized coalescent waxy papules and diffuse periorbital swelling. Systemic examination was unremarkable except for limited finger flexion. Serum electrophoresis and thyroid function tests were normal. Histopathological examination showed normal epidermis and intradermal mucin deposition, which was diagnostic of lichen myxedematosus (LM). The patient showed prompt response to melphalan...

Discrete papular lichen myxedematosus (DPLM), asubset of localized lichen myxedematosus, is a rarecutaneous mucinosis of unknown etiology. We reporta case of a 57-year-old woman with palmoplantarpsoriasis who developed DPLM 8 weeks after addingustekinumab to a long-term course of methotrexate.The patient had previously failed 2 prior tumor necrosisfactor (TNF) inhibitors, adalimumab and etanercept.This case demonstrates an association between TNFinhibitor and ustekinumab use in a psoriasis patientand localized lichen myxedematosus for the secondtime in the literature...

Acral persistent papular mucinosis (APPM) is a rare subtype of localized lichen myxedematosus. It consists of small papules localized exclusively on the back of the hands, wrists and extensor aspects of distal forearms with no other clinical or laboratory manifestations. The lesions tend to persist and may increase slowly in number. Histologically, hematoxylin-eosin and Alcian blue staining demonstrate mucin accumulation in the upper reticular dermis with separation of collagen fibers as a result of hyaluronic acid deposition...

Scleromyxedema or lichen myxedematosus is a rare papular mucinosis of chronic and progressive course and unknown etiology. It is commonly associated with monoclonal gammopathy and may show extracutaneous manifestations, affecting the heart, lung, kidney, and nerves. The diagnosis is based on four criteria: generalized papular and sclerodermoid lesions; mucin deposition, fibroblast proliferation, and fibrosis in the histopathology; monoclonal gammopathy; and no thyroid disorders. This article reports the case of a scleromyxedema patient with a recent history of acute myocardial infarction and monoclonal gammopathy...

BACKGROUND: Lichen myxedematosus (LM) is a rare, chronic idiopathic disorder characterized clinically by waxy, closely set papules and histopathologically by diffuse dermal mucin deposition and fibroblast proliferation. The most recent classification of LM was proposed in 2001; however, it seems to be complex, confusing, and imprecise. Herein, we present seven cases of LM to evaluate the validity of the current classification, to propose new diagnostic criteria and classification, and to suggest a clinically relevant severity grading system for this rare disorder...

We present an original case report of a 45-year-old woman with a five-month history of sporadic, tender, nodules present on the right upper abdomen, bilateral dorsal wrists, right upper arm, and left flank. Biopsy revealed a mild perivascular infiltrate, increased dermal mucin, and no significant increase in fibroblasts. Presentation and histology were most consistent with nodular lichen myxedematosus (NLM), a rare primary mucinosis. Only four previous cases are reported in the literature to our knowledge. Management of NLM and other subtypes of lichen myxedematosus is not well described...

BACKGROUND: Discrete papular lichen myxedematosus (DPLM) is a rare form of localized lichen myxedematosus that presents with skin involvement only and without systemic involvement. OBJECT: To describe our experience with atypical cases of DPLM associated with monoclonal gammopathy. METHODS: Data were collected from patients with clinicopathological evidence of DPLM associated with monoclonal gammopathy who presented to the Department of Dermatology of two tertiary university-affiliated medical centres from 2000 to 2015 and were followed prospectively...
