Diabetes mellitus
is a common condition, and persons who have this ailment are commonly encountered by dermatologists and primary care physicians. Because glucose attaches to long-lived proteins, it may have a profound effect on the tertiary structure of the protein. Chronic hyperglycemia may be responsible for the pathogenesis of many diabetic complications. It has been suggested that increased cross-linking of collagen in diabetic patients is responsible for the fact that their skin is generally thicker than that of nondiabetics. Advanced glycosylation end-products are probably responsible for yellowing of skin and nails. Increased viscosity of blood caused by stiff red blood cell membranes results in engorgement of the postcapillary venules in the papillary dermis, which is detected as erythema of the face or as periungual erythema. It is suggested that these skin changes may eventually be used as a reflection of the patient's current (as well as past) metabolic status.

The cutaneous microvasculature is organized into upper and lower horizontal plexuses with the dermal capillary loops arising from the upper plexus. The arteriolar and venular sides of the microvasculature can be identified by the ultrastructure of the mural basement membrane material. Collecting venules present in the lower dermis contain valves. Periadventitial cells (veil cells) are present around all microvessels. Their size and number appear to correlate with the quantity of mural basement membrane material found in cutaneous vessels in
diabetes
, actinic damage, and chronological aging. The contractile cells of the vascular wall surround the endothelial cell tube in a manner suggesting specific functions. The smooth muscle cells in the arteriolar segment form a sleeve, whereas each pericyte in the postcapillary venular simultaneously makes many contacts with several underlying endothelial cells. The common telangiectases can be explained by abnormalities in this organization and ultrastructure rather than by neovascularization or random anastomoses. The macular telangiectases seen in scleroderma, generalized essential telangiectasia, and nevus flammeus are produced by dilatation of the postcapillary venules of the upper horizontal plexus. Cherry angiomas are produced by spherical and tubular dilatations of capillary loops in dermal papillae with tortuous cross-connections between individual loops. Angiokeratomas of Fabry and Fordyce have the ultrastructure of collecting venules that contain valves, and appear to represent the ectopic development or placement of small valve-containing collecting veins. The cutaneous lesions of hereditary hemorrhagic telangiectasia represent arteriovenous communications.

In order to determine the basal insulinemia levels, the blood insulin levels have been radioimmunoassayed in psoriasis patients over the course of the routine glucose tolerance test. Hyperinsulinism, depending on the severity of the psoriatic process, has been revealed in 49 of the 64 examinees. Three types of insulin response to glucose load, similar to those in
diabetes mellitus
, have been revealed in the patients with psoriasis.

Resident skin flora consists of coagulase-negative staphylococci, micrococci, aerobic and anaerobic coryneform organisms (i.e. propionibacterium acnes) as well as gram-negative rods (i.e. acinetobacter). Their growth is favoured by increased temperature and humidity and modified by body location, age, sex and chronic diseases (i.e.
diabetes mellitus
). Occupation, hospitalization, soaps and disinfectants as well as medications exert promoting and inhibiting influences, too. In addition, environment gains significant importance due to trauma and implants as well as contact with animals, infected persons and carriers. Whereas bacteria attach by adhesins and succeed other bacteria by factors of pathogeneity such as exotoxins, exoenzymes, bacteriocins and various interference mechanisms, skin exerts its resistance and defense by means of the intact horny layer, proliferation and desquamation, lipids and fatty acids as well as sweat, in addition, by means of IgA and the specific skin immune system with complex interactions between Langerhans-, TH-, TS- and cytotoxic T-cells, interleukins and cytokines. Furthermore the non-specific defense system (complement, NK-cells, granulocytes, mononuclear phagocytic system, inflammation) is involved. Finally, skin infections caused by resident bacterial flora are briefly discussed.

Patients with renal disease or
diabetes mellitus
often have an acquired perforating disease of the skin develop that is characterized by hyperkeratotic papules with transepidermal elimination of degenerated material, including collagen or elastic fibers. There is disagreement regarding the most appropriate name for this disease. The pathologic process has been identified by various authors as reactive perforating collagenosis, elastosis perforans serpiginosa, perforating folliculitis, or Kyrle's disease. We have seen four patients with renal disease and/or
diabetes
whose skin biopsy specimens demonstrated combined transepidermal elimination of both collagen and elastic fibers. This finding is not characteristically seen in any of the previously defined perforating diseases. Since the histologic findings vary greatly in different lesions from different patients with renal disease, we recommend referring to this process as "acquired perforating dermatosis." It is best not to create a new category of perforating disease or to say that a given patient has one of the other four diseases based on random sampling of only a few lesions.

Basing on analysis of case histories of 264 diabetics, the authors have developed an original classification of the dermatoses occurring in
diabetes mellitus
. Clinical and laboratory findings evidence the identity of changes in the peripheral blood levels of calcium and immunoreactive insulin in the patients with psoriasis, neurodermatitis, and
diabetes mellitus
.

Serum monoamine oxidase, diamine oxidase and lysyl oxidase-like activity were measured in patients with granuloma annulare (GA), necrobiosis lipoidica (NL) and
diabetes mellitus
. In
diabetes
, all enzyme measurements were raised by a factor of about 2 X 2, and in NL by a factor of about 1 X 5. The rise in patients with GA was small and only significant in the case of benzylamine monoamine oxidase. "Stiff' collagen would seem to link these three disorders and the present results suggest that these amine oxidases could be useful in monitoring collagen abnormality in
diabetes
and
diabetes
-associated disorders, particularly in the absence of chronic liver disease. A negative correlation was found between enzyme activity and blood glucose levels, thus collagen changes in these conditions may occur independently of elevated blood glucose levels. Possible involvement of these enzymes in angiopathy remains to be elucidated.

Clinical and laboratory records of 100 biopsy-proved cases of generalized granuloma annulare seen at the Mayo Clinic between 1966 and 1986 were reviewed. The skin eruption involved predominantly annular lesions in 67 patients and predominantly nonannular papules in 33. The ratio of female-to-male patients was 2.9:1 in the annular group and 1.4:1 in the nonannular group. The mean age at onset was 51.7 years. The eruption was symptomatic in 34 patients, and specific precipitating factors could be implicated in 16 patients. No consistently associated systemic disorders were identified.
Diabetes mellitus
was diagnosed in 21% of our referral group of generalized granuloma annulare cases, compared with 9.7% in 1350 cases of localized granuloma annulare and 10.3% in 1383 cases of all forms of granuloma annulare seen at the Mayo Clinic in the same period. Serum lipid abnormalities were more common in the generalized annular group. Follow-up data indicated a chronic, relapsing course in most patients.
