Introduction

Background

Bullous disease of diabetes (bullosis diabeticorum) is a distinct, spontaneous, noninflammatory, blistering condition of acral skin unique to patients with diabetes mellitus. Kramer first reported bullouslike lesions in diabetic patients in 19301 ; Rocca and Pereyra first characterized this as a phlyctenar (appearing like a burn-induced blister) in 1963.2 Cantwell and Martz are credited with naming the condition, bullous diabeticorum, in 1967.3 It is also termed bullous disease of diabetes and diabetic bullae.

Also see the eMedicine articles Diabetes Mellitus, Type 1 and Diabetes Mellitus, Type 2.

Pathophysiology

The etiology of bullous disease of diabetes (bullosis diabeticorum) is not known. Patients with diabetes have been shown to have a lower threshold for suction-induced blister formation, and because of the acral prominence of diabetic bullae, the role of trauma has been speculated; however, this alone does not explain the often spontaneous development of multiple lesions at several locations. The pathophysiology is likely multifactorial.

Many, but not all, patients with bullous disease of diabetes (bullosis diabeticorum) have nephropathy or neuropathy; some authors have hypothesized an etiologic association, possibly related to a local, subbasement, membrane-zone, connective-tissue alteration. Hyalinosis of small vessels noted on biopsy specimens has led some authorities to speculate microangiopathy-associated blister induction. In some, the blisters are related to UV exposure, especially in patients with nephropathy.4 Glycemic control does not appear to have a direct correlation with blister formation.

Some electron microscopic evidence has suggested an abnormality in anchoring fibrils. A reduced threshold to suction-induced blister formation in diabetic persons as compared with nondiabetic controls has been reported.5 Prominent acral accentuation of these lesions suggests a susceptibility to trauma-induced changes, but the definitive explanation awaits elucidation.

Frequency

United States

Bullosis diabeticorum tends to arise in patients with long-standing diabetes mellitus or with multiple complications of the disease. Bullous disease of diabetes has been reported to occur in approximately 0.5% of diabetic patients. The frequency may be higher because the occurrence of blistering is likely under-reported. Patients with uncomplicated or newly diagnosed disease, including type 2 diabetes, also may be affected.

Mortality/Morbidity

Bullous disease of diabetes lesions often heal without significant scarring, but they may be recurrent and may lead to ulceration.4 One report has described osteomyelitis arising at a site of bullosis diabeticorum.6 In a reported series of 12 patients with diabetic bullae, one required amputation because of infection.7

Sex

A male-to-female ratio of 2:1 is reported in the literature for bullous disease of diabetes.

Age

The reported age of onset of bullous disease of diabetes ranges from 17-84 years.

Clinical

History

  • Bullous disease of diabetes blisters occur spontaneously and abruptly, often over night, and usually without known antecedent trauma.
  • Bullous disease of diabetes lesions tend to be asymptomatic, although mild discomfort or burning has been described.
  • Bullous disease of diabetes blisters heal spontaneously within 2-6 weeks of onset.

Physical

  • Bullous disease of diabetes (bullosis diabeticorum) manifests as tense, nontender blisters arising on nonerythematous skin. Some blisters may be flaccid.
  • Bullous disease of diabetes blisters typically occur on the feet or lower legs (see Media File 1), but they also may occur on fingers, toes, hands, and arms.

  • Bullous disease of diabetes blisters tend to be large (from 0.5-17 cm in diameter), often with an irregular shape (see Media File 2), simulating a burn.

  • Rarely, nonacral sites (eg, trunk) may be involved.

Causes

  • Prominent acral accentuation of bullous disease of diabetes lesions suggests a susceptibility to trauma-induced changes, but the definitive explanation awaits elucidation. Neuropathology, UV exposure, and microangiopathy associated with diabetes also are thought to play a role.
