Bullous Disease of Diabetes (Bullosis Diabeticorum)

Acanthosis nigricans, acrochordrons, diabetic dermatopathy, necrobiosis lipoidica, and bullous diabeticorum are some of the cutaneous symptoms of diabetes. Bullous illness (bullosis diabeticorum) is a blistering, non-inflammatory condition of the acral skin. Diabetes bullous illness is more common in people who have had diabetes for a long time or who have many comorbidities. Although the actual cause is uncertain, it is likely to be multifactorial. Neuropathy, nephropathy, vasculopathy, and UV (ultraviolet) light are all suggested to have a role. BD is most likely caused by the various problems that come with poorly managed diabetes. The exact number of people who have BD is unknown. The majority of case studies in the literature were based on a small number of cases. Bullous diabeticorum is a restrictive diagnosis, which necessitates a histological study that includes direct immunofluorescence to rule out other vesicobullous illnesses. In terms of BD management, no strong consensus has formed. The blisters have historically been thought to be self-limiting, with bullae resolving in 2 to 6 weeks if left untreated. In some cases antibiotic may be used. In this article we’ll be looking at Bullosis Diabeticorum. Its etiology, epidemiology, diagnosis, and treatment.

Necrobiosis lipoidica: a rare clinical and pathomorphological case

According to modern scientific researches, necrobiosis lipoidica (NL) is a disease characterized by focal disorganization and lipid collagen dystrophy. It is believed that the basis of skin changes in this dermatosis is diabetic microangiopathy that is accompanied by sclerosis and obliteration of blood vessels, which leads to necrobiosis with subsequent deposition of lipids in the dermis. This pathology is registered relatively rarely, in 1 % of patients with diabetes mellitus (DM) on average. The combination of NL with DM, according to the literature data, ranges from 25 to 70 %; more often (in 40–60 % of cases) DM is preceded by NL, and in 10–25 % of cases they occur simultaneously. In addition, in 10–50 % of cases NL is diagnosed in people without concomitant diabetes. The variability of clinical, epidemiological features and the relatively low prevalence of this pathology is often the cause for misdiagnosis or late diagnosis. The described clinical case is typical in terms of the epidemiological data: sex, age, presence of DM. At the same time, it is rare in terms of the clinical picture: it is not classically diabetic by localization (symmetrical areas of the legs are typical), by appearance of necrobiosis areas — granulomatous type of necrobiosis in the form of granuloma annulare, by histological structure — area of chronic perivascular lymphoplasmocytic inflammation with the involvement of single giant cells, which required additional clinical and anamnestic data for an objective report of the pathologist. Biopsy in this case was used as a differential diagnosis between granuloma annulare and necrobiotic necrogranuloma. In addition, this method of diagnosis has played an additional therapeutic role. This case may have demonstrated the activation of the cellular and humoral immune response in the area of chronic inflammation in response to a mechanical damage and the resolution of inflammation with complete tissue repair.

Necrobiosis Lipoidica: Atypical Presentation in a Diabetic Girl

Necrobiosis lipoidica (NL) is a chronic granulomatous idiopathic disorder. It usually presents as yellow-brown, atrophic, telangiectatic plaques with an elevated violaceous rim, typically in the pretibial region of both extremities with and without ulceration [1, 2]. There are few reported cases of childhood-onset NL in atypical locations. We report a case of type 1 diabetic 13-year-old girl who developed yellow atrophic plaque with telangiectasia on the extensor aspect of her upper arm.
