Localized amyloidosis of the bladder treated effectively by occlusive dressing technique therapy using Dimethyl sulfoxide (DMSO): two case reports

The first case is a 50-year-old female. She was consulted to our hospital for further examination of right hydronephrosis that was shown by ultrasonography. Cystoscopy revealed tumorous lesion around the right orifice. Bladder tumor was suspected and transurethral biopsy of the bladder was performed. The second case is a 54-year-old man. He was consulted to our hospital because right hydronephrosis was shown by counterized tomography. A tumorous or stenotic lesion in the lower end of ureter was suspected. Cystoscopy revealed yellowish and thickened tissue in the trigonal area. Bladder amyloidosis was suspected and transurethral biopsy of the bladder was performed. The histopathological diagnosis indicated amyloidosis and systemic amyloidosis was excluded. Both cases were treated by occlusive dressing technique therapy using Dimethyl sulfoxide (DMSO) successfully.     

Localized amyloidosis of the ureter: a case report

A 58-year-old woman was introduced to our department complaining of lower abdominal pain and macrohematuria in March, 1978. Intravenous pyelography revealed stenosis and a ureteral stone on the right distal ureter. In May, 1983, she visited our department again. Endoscopically, bleeding from the right ureteral orifice was observed. Retrograde pyelography demonstrated the right hydronephrosis and irregular margin of the right lower ureter. However, the urine cytology was negative, and CT scan and ureteroscopy showed no tumorous lesion on the portion. On 7 August, 1989, partial ureterectomy and end to end anastomosis was performed. Histopathological examination by H-E and Congo red stain proved amyloid deposition. Postoperative course was uneventful. A total of 40 cases of amyloidosis of the ureter in the world are reviewed.     

Localized amyloidosis of the ureter: a case report

A 46-year-old female was referred to our hospital with a complaint of left flank pain. Ultrasongraphy and computed tomography demonstrated a left hydronephroureter due to stenosis with a ureteral mass in the left lower ureter. Retrograde pyelography revealed severe stricture of left lower ureter and brushing cytology showed papanicolaou class III. Ureteral tumor was suspected and left nephroureterectomy with partial cystectomy was performed. Histopathological diagnosis was amyloidosis of the left ureter. There was no evidence of secondary or systemic amyloidosis. Finally, we diagnosed her with localized amyloidosis of the left ureter. Localized amyloidosis of the ureter is a relatively rare condition, and this is the 55th case reported in the Japanese literature.     

Localized amyloidosis of the ureter: report of a case

A case of primary amyloidosis of the ureter is presented. The patient was a 48-year-old woman with a 5-year history of asymptomatic macrohematuria. Roentgenographic examination showed left hydronephrosis and stenosis of the left distal ureter. Histological examination of the biopsied specimen during the operation revealed no malignancy; and, left partial ureterectomy and uretero- vesiconeostomy was performed. Congo red stain proved amyloid deposition after surgery. Rectal biopsy was negative for amyloid; and, other laboratory findings were within normal range. Thus it was diagnosed as a primary localized amyloidosis of the ureter. Importance of intraoperative histologic examination was discussed. This is the 22nd case in the literature.     

Localized amyloidosis of urinary bladder: a case report

A case of localized amyloidosis of the urinary bladder is reported. A 82-year-old woman visited our hospital with the chief complaint of miction pain and residual urine sensation. Cystoscopic examination revealed a broad-based and nonpapillary tumor without bleeding on the right lateral wall. A transurethral biopsy of this tumor was performed. A histopathological examination with H.E. and Congo red stains demonstrated amyloid deposition in the submucosal layers of the vesical wall. Rectal biopsy and other findings suggested no deposition of amyloid in other organs. On the basis of these findings, we made a diagnosis of localized amyloidosis of the urinary bladder. To the best of our knowledge, the present case is the 23rd of localized amyloidosis of urinary bladder in Japan. The patient was asymptomatic after biopsy. We discuss the clinical features and management of this disease.     

Localized amyloidosis of the urinary bladder: a case report

Amyloidosis is characterized by extracellular deposition of abnormal insoluble fibrils, which cause structural and functional disorders. Amyloidosis is classified into systemic and localized amyloidosis. Localized amyloidosis in individual organs is uncommon. We report a rare case of localized form of primary amyloidosis of the urinary bladder. A 76-year-old male visited our hospital with a complaint of macroscopic hematuria. Cystoscopy showed submucosal hematoma in the anterior wall and broad-based mass occupying the trigone without normal mucosa covered by calcification. Transurethral biopsy and resection were performed. Histopathological diagnosis was AL type amyloidosis occupying submucosal extracellular space. We gave the patient occlusive dressing with dimethyl sulfoxide. In 12 months, cystoscopy and magnetic resonance imaging revealed improvement of the mass-like lesion in the bladder wall.     

Primary localized amyloidosis of the bladder: experience with dimethyl sulfoxide therapy

PURPOSE: We present our long-term experience with intravesical dimethyl sulfoxide (DMSO) for primary localized amyloidosis of the bladder. MATERIALS AND METHODS: The study included 4 males and 2 females 28 to 68 years old (mean age 54) at diagnosis of biopsy proven primary localized amyloidosis involving the bladder diffusely or extensively in 1 locale. All patients had normal upper urinary tracts. They continued to be symptomatic (hematuria in 3, irritative voiding symptoms in 1, and hematuria and irritative voiding symptoms in 2) despite conventional transurethral destructive therapy. Every 2 weeks they received 30-minute instillations of 50 ml. 50% DMSO intravesically for 3 months (patient 1), 6 months (1) and 1 year (4). RESULTS: Therapy failed at 3 and 6 months in 2 patients of whom 1 with a contracted bladder underwent cystectomy and another was stabilized for 1 year with laser therapy. In the remaining 4 patients who were followed for 6 years disease stabilized for 2 to 6 years (mean 3.5) but 3 later required additional therapy including repeat DMSO in 1 and laser therapy in 2. CONCLUSIONS: Diffuse or locally extensive bladder involvement by primary localized amyloidosis usually fails to respond to conventional transurethral destructive surgical procedures. Collectively, our experience and the literature suggest that intravesical DMSO can be a bladder saving measure and help resolve ureterovesical obstruction in some patients. High recurrence rate mandates lifelong cystoscopic surveillance.     

Intravesical dimethyl sulfoxide for primary amyloidosis of the bladder

Primary bladder amyloidosis is a rare disease. Treatment recommendations are necessarily anecdotal. We report a case of a 52-year-old woman treated successfully with intravesical dimethyl sulfoxide instillation.     

Primary localized amyloidosis of the bladder: a case of AL (lambda) amyloid protein and combination therapy using dimethyl sulfoxide and cepharanthin.

We report a case of primary localized amyloidosis of the bladder with amyloid deposits which was characterized as being of immunoglobulin light chain origin (AL) including lambda type (A lambda) and P component (AP) using the KMnO4 pretreatment method and immunohistochemical procedures. The patient was treated successfully with intravesical dimethyl sulfoxide instillation and oral administration of high-dose cepharanthin after transurethral resection. Combination therapy with dimethyl sulfoxide and cepharanthin was shown to be useful for primary localized amyloidosis of the bladder.     

Localized pleural amyloidosis: report of a case

We herein describe an asymptomatic 31-year-old male who was admitted for an investigation of an abnormal pleural tumor detected by chest radiography. We performed various preoperative investigations including fluorodeoxyglucose-positron emission tomography. The maximum standardized uptake value (SUVmax) was 2.2, and malignancy could not be ruled out. We therefore carried out a thoracoscopy-assisted partial resection of the right upper lobe combined with a parietal pleurectomy. The pathological examination showed that there was a tumor localized with pleural amyloidosis.     

Danazol therapy of endometriosis of the bladder and ureter: a case report

Endometriosis of the urinary tract is uncommon. A thirty-year-old woman was referred to our hospital, complaining of macrohematuria. Intravenous pyelography (IVP) showed bilateral hydro nephrosis. Cystoscopic examination revealed a mass around the bilateral ureteral orifice. Danazol therapy was commenced. After 6 months of therapy, IVP showed the improvement of hydronephrosis of left kidney and cystoscopy revealed the resolution of most of the mass in the bladder. For definite diagnosis and treatment, danazol therapy is considered to be effective for endometriosis, but if secondary fibrosis has occurred, surgical treatment may be necessary.     

Idiopathic calcinosis cutis in fingertip treated with occlusive dressing using aluminum foil: a case report.

Calcium deposition in the skin, known as calcinosis cutis, is an uncommon disorder caused by an abnormal deposit of calcium phosphate in the skin. We report a case of idiopathic calcinosis cutis in fingertip treated with surgical excision followed by the occlusive dressing using aluminum foil, and obtained significant pain relief and round-shaped fingertip which looked normal.

Colchicine therapy in primary amyloidosis of the bladder: a case report

A patient with diffuse localized amyloidosis of the bladder was considered for cystectomy because of intractable gross hematuria. Oral colchicine (2 mg. daily) was commenced and 4 years later the patient was asymptomatic with minimal evidence of amyloidosis cystoscopically.     

Localized amyloidosis of the seminal vesicle: a case report

Primary amyloidosis of the seminal vesicle is a rare disease entity. We report here a case of localized seminal vesicle amyloidosis with hematospermia. A 66-year-old man visited our hospital with a chief complaint of hematospermia. T2 weighted magnetic resonance imaging (MRI) showed a hypointensity mass in the left seminal vesicle. Needle biopsy revealed amyloidosis of the seminal vesicle. Without any specific treatment, the mass lesion disappeared on MRI, and hematospermia was improved.     

Experience with dimethyl sulfoxide treatment for primary localized amyloidosis of the bladder

We report a case of primary localized amyloidosis of the bladder treated successfully with transurethral resection and intravesical dimethyl sulfoxide instillation. Dimethyl sulfoxide bladder instillation is useful for the treatment of primary localized amyloidosis of the bladder.
