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.

A 61-year-old Japanese woman with heterozygous familial hypercholesterolemia (FH),
type 2 diabetes
mellitus and coronary artery disease underwent coronary artery bypass grafting (CABG) utilizing a saphenous vein graft at the age of 46, in June 1984, 6 months before low density lipoprotein (LDL) apheresis was started. She had received LDL apheresis every two weeks, along with combined drug treatment since the age of 47 (December 1984). She had bilateral
xanthelasma
and Achilles tendon xanthomas. Her fasting baseline serum total cholesterol and triglyceride level were 464 mg/dl and 57 mg/dl, respectively at the age of 47 when she visited our hospital for the first time. Analysis of the genomic DNA from the patient revealed heterozygous amino acid substitution of Leu for Pro664 in the LDL receptor gene. She was diagnosed as
type 2 diabetes
mellitus at the age of 53. Combined treatment in the steady state yielded a pretreatment LDL cholesterol level of 230+/-14 mg/dl and a posttreatment level of 57+/-7.6. All grafts were widely patent after as long as 14 years since CABG, suggesting that LDL apheresis combined with drug therapy is highly effective in preventing the occlusion of bypass grafts in a patient with heterozygous FH and
type 2 diabetes
mellitus.

Xanthoma
and
xanthelasma
are typical symptoms of lipid and lipoprotein metabolism impairment. On the basis of their incidence and morphology, it is even possible to specify the impairment type. Hypercholesterolemia or certain liver dysfunctions are characterized by slow development of surface xanthelasmas usually located on mechanically stressed regions (e.g. eyelids). Tuberous and tendinous xanthomas are typical for familiar hypercholesterolemia and are common symptoms of homozygous familiar hypercholesterolemia. Small and quickly developing eruptive xanthomas are typical for mixed hyperlipoproteinemia (secondary hyperlipoproteinemia is typical for diabetes). Mechanism of accumulation of lipids in skin morphs is similar to the development of atheroma, especially when talking about the role of modified LDL and the way of accumulation of lipids in macrophages. The following factors are very important for etiopathogenesis of skin xanthomas development: mechanical stress of tissues, increased permeability of skin capillaries and reaction of proteoglycans in sparse connective tissue.
Xanthomas
and xanthelasmas are typical indicators of other complicating diseases as e.g. development of acute pancreatitis during hyperlipoproteinemic crisis, aggravation of insulin resistance, and decompensation of
type 2 diabetes
mellitus. The therapy focuses on adjustment of dietary regime (elimination of dietary fat and concentrated saccharides); no food and sufficient hydration via infusion of crystalloid solutions is indicated in cases of serious hyperlipoproteinemic crisis. In vital indication, it is possible to perform repeated plasmapheresis (or better continual plasmapheresis) that can correct even serious hyperlipoproteinemic crises within several hours. And what is more, continual plasmapheresis can significantly reduce the period when hyperlipoproteinemic crisis might induce acute necrotizing pancreatitis. In the long run, we require that patients strictly observe their dietary regime based on the type of hyperlipoproteinemia. As for medicamentous therapy, fibrates and atorvastatin (from statin family) are the preparations of choice. It is very important not to focus on symptoms, i.e.
xanthoma
or
xanthelasma
, but fully compensate lipid metabolism impairment or the disease that underlies hyperlipoproteinemia (e.g.
type 2 diabetes
mellitus or metabolic syndrome). Unfortunately, it still can be seen that dermatologists, ophthalmologists or plastic surgeons remove extensive xanthelasmas, while the underlying cause is not approached diagnostically and therapeutically at all.

Numerous skin lesions have been commonly observed in individuals with diabetes mellitus. The common skin manifestations of diabetes mellitus are erythrasma, xanthomatosis,
xanthelasma
, phycomycetes and cutaneous infections like furuncolosis, candidiasis, carbuncle, dermatophytosis, etc. Diabetic dermopathy is the most common skin lesion found in patients with diabetes. It is typically seen in men aged above 50 years. In low-level laser therapy (LLLT), the entire lower limb was illuminated with the frequency of 20 Hz and wavelength of 830 nm for 9 min, and the treatment was divided into four parts. With the continued sessions of LLLT, the skin manifestations and neuropathy conditions improved drastically. On the 21st day, the skin colour was found to be normal. Also, there were significant changes in clinical findings for diabetic peripheral neuropathy. LLLT with specific exercises can promote healing of skin manifestations in individuals with
type 2 diabetes
mellitus. It can be used as an effective treatment modality for treating diabetic dermopathy.

Soft-drink diabetic ketosis, characterized by acute onset ketosis induced by excessive ingestion of sugar-containing drinks, is often seen in obese, young patients, even with undiagnosed
type 2 diabetes
. We herein report a 15-year-old obese patient with the apolipoprotein E4/2 phenotype, in whom eruptive xanthomas lead to a diagnosis of soft-drink diabetic ketosis. He developed multiple asymptomatic yellowish papules on the auricles, back, buttocks and the extensor surfaces of the elbows and knees. He initially visited a dermatology clinic and his blood triglyceride and HbA1c levels were found to be 6,490 mg/dL and 16.5%, respectively. He was referred to our hospital for treatment of hyperglycemia and hypertyriglyceridemia. On admission, he had ketonuria and increased blood levels of 3-hydroxybutylate and acetoacetate. He habitually drank 1-3 litters of sweet beverages daily to quench his thirst. Therefore, "soft-drink diabetic ketosis" was diagnosed. Severe hypertriglyceridemia was considered to have been a consequence of impaired insulin action and his apolipoprotein E4/2 phenotype. We treated the diabetic ketosis and hypertriglyceridemia with intensive insulin therapy and a fat-restricted diet. At discharge, he no longer required insulin therapy and his blood glucose levels were controlled with metformin and voglibose. Along with amelioration of the hyperglycemia, triglyceride levels decreased to 247 mg/dL without administration of anti-hyperlipidemia agents. The eruptive
xanthoma
lesions gradually diminished in size and number and eventually disappeared by 12 months. This case provides an instructive example of eruptive xanthomas serving as a sign of severe dysregulation, not only of lipid, but also glucose, metabolism.
