In an electron-microscopic study of the skin of a patient with scleredema adultorum (Buschke) and diabetes mellitus, the unmyelinated nerve fibres showed accumulations of glycogen. On morphological grounds, these accumulations appeared to be located in the axons.

We studied 26 formalin-fixed biopsy specimens taken from 22 patients with scleredema and found positive staining in 67% of the tissues when both colloidal iron and alcian blue methods were used. Single stains were positive in only half the tissues. Positive findings were noted in both patients with diabetes (11 patients) and in those without it (11 patients). Our experience indicates that multiple biopsies may be necessary to demonstrate mucin in the dermis. Specimens obtained by incisional biopsy are preferred.

We report a classical case of scleredema which pursued a chronic progressive course and was associated with poorly controlled diabetes mellitus.

A study of non-infective skin associations of diabetes mellitus was conducted on 100 consecutive outpatient diabetics over a 3-month period. 10 were insulin-dependent diabetics (IDDM), 24 insulin-requiring and 66 non-insulin dependent diabetics (NIDDM). A total skin evaluation was done for each patient with skin biopsy whenever appropriate. Twenty-three patients had diabetic dermopathy; the frequency of retinopathy in this group (39.1%) is significantly higher than that without diabetic dermopathy (6.9%) (p less than 0.001). There were 20 instances of cutaneous complications of therapy; 10 had insulin lipodystrophy (29.4% of 34 insulin users). Twelve patients, 8 of whom were overweight, had acanthosis nigricans. There were 6 Indians among them and all the patients had NIDDM. Eight had xanthelasma. Vitiligo occurred in 3.3% of those with NIDDM. Classical scleredema diabeticorum and cheiroarthropathy occurred in 2% of patients. One patient had atypical granuloma annulare. There was a higher incidence of xanthelasma in our study compared with studies done previously. Insulin lipodystrophy and acanthosis nigricans in the absence of classically described syndromes of insulin resistance seem to be fairly common phenomena and merit further investigation locally.

Many skin lesions are specific for diabetes mellitus. Necrobiosis lipoidica, lipoatrophy and idiopathic bullae (bullosis diabeticorum) are usually associated with diabetes. However, diabetic scleredema has not been noticed by internists, although dermatologists have paid attention to such a cutaneous manifestation. We reported a clinical case of a female diabetic patient aged 15 who had been afflicted with diabetic scleredema. She had been treated with insulin since 5 years of age. She noticed stiffness of the skin in April 1980. Skin biopsy showed thickness of the dermis and accumulation of acid mucopolysaccharide. After control of blood glucose with continuous subcutaneous insulin infusion (CSII) and administration of tocopherol acetate and hyaluronidase, the skin lesion improved. Etiology of diabetic scleredema is unknown. Such skin lesion which is observed frequently in insulin dependent obese patients is different from a category of scleredema of Buschke.

A review of thirty-three cases of scleredema, with particular reference to clinical and histologic findings, revealed that the disease was often of insidious onset and the course was usually prolonged. A preceding respiratory tract infection was uncommon and usually did not indicate a short course. The patients were divided into two groups according to the presence or absence of diabetes. Diabetes, when present, was typically the late-onset, insulin-dependent type and difficult to control. In many of these patients, the onset of scleredema was so subtle that it went unnoticed by the patient until pointed out by an examining physician.

Scleredema diabeticorum is characterized by a dramatic increase in the thickness of the skin of the posterior neck and upper back. Of the 17 scleredema patients diagnosed by us in the last 15 yr, 16 have had type II diabetes mellitus. In a prospective study of 484 diabetic outpatients we found the prevalence of scleredema to be 2.5%. Angina pectoris was the only complication that occurred significantly more frequently in scleredematous diabetic patients than in a control group of diabetic patients without scleredema. Scleredema diabeticorum is a distinct cutaneous condition peculiar to diabetic individuals and ought not to be confused with scleredema of Buschke or scleroderma.

To elucidate the mechanisms involved in the development of cutaneous fibrosis in scleredema adultorum, we studied a patient with long-standing scleredema who had no history of diabetes mellitus or preceding febrile illness. Histological examination of a biopsy specimen from involved forearm skin demonstrated marked thickening of the dermis and accumulation of mucin between collagen bundles. Increased levels of type I collagen mRNA, as evidenced by positive in situ hybridization signals with an alpha 1(I) procollagen cDNA were found in numerous fibroblasts throughout the dermis. The expression of several genes coding for proteins involved in the maintenance of connective tissue was examined by determining in vitro protein production and mRNA levels in fibroblasts from the affected skin. Total protein production, glucosamine incorporation and collagen synthesis, were elevated by 44-97% in scleredema fibroblasts, compared with fibroblasts from two healthy individuals. Levels of mRNAs for alpha 1(I) and alpha 1(III) procollagens and fibronectin were elevated in scleredema fibroblasts, whereas mRNA levels for the tissue inhibitor of metalloproteinase were unaltered compared with control cultures. The results suggest that fibroblasts from the involved skin in non-diabetic patients with scleredema may exhibit a biosynthetically activated phenotype, which persists for several years. These alterations are likely to be involved in the development of the cutaneous induration and thickening which is characteristic of this disease.

A 21-year-old housewife with maturity onset type diabetes of young people developed scleredema diabeticorum, scleroderma-like skin thickness on forearms and dorsum of hands, digital sclerosis and cheiroarthropathy. She had diabetes mellitus since the age of 11 years. Her grandfather on the mother's side, her mother and 3 of 5 her mother's brothers and sisters have diabetes mellitus. Blood glucose was 295 mg/dl. Urinary glucose was 5.3 g/day. Nail fold capillary microscopy revealed a progressive systemic sclerosis pattern. Histologically, hematoxylin and eosin sections from back and forearm skin demonstrated broad collagen bundles separated by widened clear spaces throughout the thickened dermis.

We describe a patient with insulin-dependent diabetes without vascular complications in whom scleredema was confined to the thighs. Electron microscopy demonstrated heterogeneity in both the size and density of the collagen fibrils and the presence of filamentous material between them.
