J Eur Acad Dermatol Venereol 2022 Jul 17;36(7):1016-1024. Epub 2022 Feb 17.

Dermatology Clinic, IRCCS San Raffaele Scientific Institute, Milan, Italy.

Cutaneous mucinoses are a heterogenous group of conditions, characterized by the deposition of glycosaminoglycans (mucin) in the dermis, follicles, or in the epidermis. Major cutaneous mucinoses include lichen myxedematosus, scleredema, mucinoses associated with thyroid disease, reticular erythematous mucinosis, papulonodular mucinosis associated with connective tissue diseases, and cutaneous focal mucinosis. The aim of this review is to provide an update of what has currently been reported in the last 30-year literature about several new or emerging conditions of acquired cutaneous mucinoses in adults.

Solitary Cutaneous Focal Mucinosis.

Cureus 2021 Oct 9;13(10):e18618. Epub 2021 Oct 9.

Dermatology, University of California, Davis Medical Center, Sacramento, USA.

Solitary cutaneous focal mucinosis is a unique condition defined by the presence of mucin, a hyaluronic acid complex, in the dermis. The lesion typically presents as an isolated, asymptomatic papule or nodule on the extremities or back and is not associated with any systemic condition. Conversely, multiple cutaneous focal mucinosis present with numerous skin lesions has been found to be associated with systemic diseases such as scleromyxedema, systemic lupus erythematous, and thyroid disease.

Department of Dermatology and Venereology, All India Institute of Medical Sciences, New Delhi, India.

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. Read More

IgG1 Subclass Restriction and Biochemical Peculiarities of Monoclonal Immunoglobulins in Scleromyxedema.

Clin Lab 2021 Mar;67(3)

Background: Scleromyxedema (SME) is a rare mucinosis associated with monoclonal gammopathy. Several biochemical peculiarities of monoclonal immunoglobulins (Ig) in SME patients were reported in case reports or short series, such as IgGλ over-representation, cationic migration, and partial deletion.

Methods: Monoclonal immunoglobulins (Ig) from the serum of 12 consecutive patients diagnosed with scleromyxedema (SME) were analyzed using electrophoretic and immunoblotting techniques. Read More

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. Read More
