Diabetic Scleredema: A Case Report and Biochemical Analysis for Glycosaminoglycans

We report a patient with the typical lesions of diabetic scleredema. Histological findings of the involved skin were thickening of the dermis, depositions of mucins, and fibrosis. Biochemical analysis revealed an increase in glycosaminoglycans in the involved skin as well as in the cutaneous lupus mucinosis. Mucinous materials were composed of hyaluronic acid.     

Morphea-like cutaneous mucinosis

A whitish, indurated, oval plaque, lasting for 1.5 year, was observed in the right paraumbilical skin of a middle-aged man in otherwise good health. No erythema was present or referred. Histological examination revealed massive deposits of a globular, slightly basophilic, amorphous substance in the dermis, accompanied by a slight perivascular mononuclear cell infiltrate and scattered mast cells. Special staining with Alcian blue at pH 2.5 confirmed the intense deposition of mucin involving the entire dermis. sparing epidermis, adnexa and perivascular areas. No abnormal laboratory results indicating lupus erythematosus or thyroid dysfunction were present. Morphea was excluded on clinical and histological grounds. A plaque-like form of cutaneous mucinosis was diagnosed. Plaque-like mucinosis and reticular erythematous mucinosis (REM) syndrome are currently considered to be the same disease, although some authors noted a different response lo treatment. Clinical presentation of our case was unusual: no erythema preceded or accompanied the plaque growth, which had a whitish, indurated, morphea-like appearance from the beginning but with preservation of hair follicles, quite different from archetypical REM syndrome based on clinical grounds.     

Hyaluronan in skin

Juhlin L (University Hospital, Uppsala, Sweden). Hyaluronan in skin (Minisymposium: Hyaluronan) J Intern Med 1997; 242 : 61–6.
Because of the abundance of hyaluronan in skin, interest was early focused on variation in the content of the polysaccharide in various pathological conditions of this tissue. A large amount of early work utilized histological techniques of insufficient specificity but recent developments of specific analytical and staining methods for hyaluronan have supplied new data on its presence and possible role in skin disorders.
