Yoshino T, Ohara S, Moriyama H - J Med Case Rep (2013)

Bottom Line: In the English literature, this is the first case effectively treated with occlusive dressing therapy using dimethyl sulfoxide.The maneuver of occlusive dressing therapy was simpler and easier than that of intravesical instillation, and occlusive dressing therapy was advantageous in that the patient could perform the therapy herself every day.However, invasive surgical management including cystectomy should be considered if conservative management is inefficacious.

ABSTRACT

Introduction: Amyloidosis is characterized by extracellular deposition of abnormal insoluble fibrils, which cause structural and functional disorders. Amyloidosis is classified into primary and secondary disease. We report a case of localized amyloidosis of the urinary bladder. In the English literature, this is the first case effectively treated with occlusive dressing therapy using dimethyl sulfoxide.

Case presentation: A 58-year-old Japanese woman was introduced to our department with asymptomatic gross hematuria. Cystoscopy revealed a gently raised nodule at the right lateral wall. Histopathological findings of this lesion revealed extensive amorphous eosinophilic deposits that stained positive with Congo red and Dylon. The patient was diagnosed with primary localized amyloidosis of the urinary bladder. To treat residual amyloidosis of the bladder, we performed occlusive dressing therapy using dimethyl sulfoxide. After treatment, cystoscopy and magnetic resonance imaging showed no relapse of the mass-like lesion of the bladder wall.

Conclusions: Occlusive dressing therapy using dimethyl sulfoxide is efficacious and tolerable for amyloidosis of the urinary bladder. The maneuver of occlusive dressing therapy was simpler and easier than that of intravesical instillation, and occlusive dressing therapy was advantageous in that the patient could perform the therapy herself every day. However, invasive surgical management including cystectomy should be considered if conservative management is inefficacious.

Mentions: To the best of our knowledge, this is the first case in the English literature of localized amyloidosis of the urinary bladder effectively treated with ODT using DMSO. Previous Japanese literature has also reported the efficacy and tolerability of ODT using DMSO for amyloidosis of the urinary bladder [10-12]. In our case, in accordance with previous reports [10-12], the gauze of the ODT was dipped in a setup 7mL dose of 50% DMSO solution. The gauze impregnated with the solution was attached to the skin of the patient’s thigh, which was covered with cling wrap for about 2 hours every day (Figure 5).
