Bladder Amyloidosis

Andrew J Einstein, Igor Shuryak, Adam Castaño, Akiva Mintz, Mathew S Maurer, Sabahat Bokhari
BACKGROUND: Increasing recognition that transthyretin cardiac amyloidosis (ATTR-CA) is much more common than previously appreciated and the emergence of novel disease-modifying therapeutic agents have led to a paradigm shift in which ATTR-CA screening is considered in high-risk populations, such as patients with heart failure with preserved ejection fraction (HFpEF) or aortic stenosis. Radiation risk from 99m Tc-pyrophosphate (99m Tc-PYP) scintigraphy, a test with very high sensitivity and specificity for ATTR-CA, has not been previously determined...

Amyloidosis is a rare disease defined by accumulation of extracellular amyloid systemically or within a specific organ. Localized amyloidosis of the genitourinary system is extremely rare, with the predominate location being the bladder. The imaging findings are often nonspecific and mimic urothelial carcinoma. We present a 49-year-old woman with a chief complaint of flank pain. A filling defect was discovered on radiological imaging. The defect was subsequently biopsied and proven to be a primary amyloidosis of the renal pelvis...

PURPOSE: To investigate the utility of Pittsburgh compound B (PiB) positron emission tomography (PET) imaging for evaluating whole-body amyloid involvement in patients with systemic amyloidosis. METHODS: Whole-body 11 C-PiB PET was performed in seven patients with systemic immunoglobulin light-chain (AL) amyloidosis, seven patients with hereditary transthyretin (ATTRm) amyloidosis, one asymptomatic TTR mutation carrier and three healthy controls. The correlations between clinical organ involvement, radiological 11 C-PiB uptake and histopathological findings were analysed for each organ...

Gross hematuria is a common occurrence in adults. The differential diagnosis is extensive, including: malignancy, trauma, inflammation of the urinary tract, and stones. While, urinary tract amyloidosis represents only a small percentage of causative gross hematuria, it is concerning because of its superficial resemblance to malignant processes. We report the case of an 82-year-old male with concurrent primary amyloidosis of the kidney, ureter and bladder in the setting of acute hemorrhage. Histopathological examination of several biopsied samples confirmed our diagnosis...

Amyloidosis is a protein folding disorder characterized by the deposition of fibrillar proteins into solid organs or tissues. Primary localized amyloidosis of the bladder is very rare and can mimic bladder cancer in its presentation with hematuria, lower urinary tract symptoms or a mass on imaging. A case of localized amyloidosis of the bladder in a 48-year-old man with painless gross hematuria and evidence of bladder mass on ultrasound is presented. Amyloidosis is a rare but important non-malignant process of the bladder...

Primary amyloidosis of the urinary bladder is a rare disease, with only approximately 200 cases reported in the literature. We herein present a case of amyloidosis of the urinary bladder with painful gross hematuria. Pelvic Computed Tomography showed uneven thickening of the bladder wall suspicious of neoplastic lesion. Cystoscopy and transurethral resection were performed. Congo-red staining confirmed amyloidosis it was. Postoperative recovery was good and close follow-up was recommended after discharged. Amyloidosis is usually benign, while it can masquerade as a malignancy...

OBJECTIVES: Cryopyrin-associated periodic syndromes (CAPS) usually start during infancy as an urticarial-like rash and a marked acute phase response, with additional manifestations appearing during its evolution. The aim of this study was to expand the clinical diversity of CAPS by the description of novel atypical features. METHODS: Clinical data were collected from patients' medical charts. Sanger sequencing analyzed NLRP3. Response to anti-IL-1 blockade was evaluated by clinical assessments and by measurements of laboratory parameters...

Primary and localized amyloidosis of the urinary tract is considered to be a rare clinical entity with approximately 160 cases documented in the literature. Here we present a case of a 77 year old gentleman with painless visible hematuria. Flexible cystoscopy revealed abnormal and polypoidal bladder mucosa. Transurethral resection of these lesions revealed histology with congo-red staining and positive green-apple birefringence, these findings are consistent with amyloidosis. There has so far been no sign of recurrence in this gentleman, with routine cystoscopic surveillance...

BACKGROUND: Secondary bladder amyloidosis is an extremely rare disease, resulting from a chronic systematic inflammatory disorder associated with amyloid deposits. Although uncommon in Japan, familial Mediterranean fever (FMF) is a hereditary autoinflammatory disease characterized by recurrent episodes of fever of short duration and serositis and is frequently associated with systemic amyloidosis. Here, we present a case of a Japanese patient complaining of fever and macroscopic hematuria after a living donor renal transplantation...

BACKGROUND: Localised immunoglobulin light-chain amyloidosis, involving one type of tissue, is rare. Little systematic data exists regarding clinical presentations, course or outcomes, or risk of progression to systemic amyloidosis. We aimed to report clinical features and outcomes of a large series of patients with localised light-chain amyloidosis. METHODS: We examined data for all patients with localised amyloidosis who were diagnosed, assessed, and followed at the UK National Amyloidosis Centre (NAC) between Jan 2, 1980, and Dec 15, 2011, from the NAC database and written records...

UNLABELLED: In this review, the clinical manifestations of urinary schistosomiasis are displayed from a pathogenetic perspective. According to the prevailing host's immune response profile, urinary schistosomiasis may be broadly categorized into cell-mediated and immune-complex-mediated disorders. The former, usually due to Schistosoma haematobium infection, are attributed to the formation of granulomata along the entire urinary tract. As they heal with excessive fibrosis, they may lead to strictures, calcifications and urodynamic abnormalities...

The clinical manifestations of schistosomiasis pass by acute, sub acute and chronic stages that mirror the immune response to infection. The later includes in succession innate, TH1 and TH2 adaptive stages, with an ultimate establishment of concomitant immunity. Some patients may also develop late complications, or suffer the sequelae of co-infection with other parasites, bacteria or viruses. Acute manifestations are species-independent; occur during the early stages of invasion and migration, where infection-naivety and the host's racial and genetic setting play a major role...

Amyloidosis is a disorder of protein folding characterized by extracellular aggregation and deposition of amyloid protein fibrils. Light-chain amyloidosis, also known as primary systemic amyloidosis, is the most common form of the disease. We present a case of an 84-year-old male with a history of systemic primary amyloidosis causing genitourinary, cardiac, and autonomic dysfunction who presented with hematuria and hypotension secondary to bladder perforation. He underwent open repair of a large extraperitoneal bladder defect...

Localized urinary tract amyloidosis (UTA) is a rare disease that mimics neoplasia clinically, cystoscopically, and radiologically. We report eleven cases of isolated UTA from the urinary bladder (n=7) and upper urinary tract including the ureter (n=2) and renal pelvis (n=2). All cases clinically presented as mass lesions prior to histologic examination and clinically suggested a neoplastic process. The amyloid composition in most cases was mixed Kappa and Lambda light chains. All cases were cured after surgical excision except one case which was diagnosed as plasmacytosis/plasmacytoma six months later...

Primary bladder amyloidosis is a rare disease, with only 200 cases reported worldwide. This condition is clinically important since it masquerades as a malignancy. We herein present a case of primary bladder amyloidosis presenting as painless hematuria and dysuria. Computed tomography and ultrasound showed thickening of the posterior bladder wall. Cystoscopy revealed abnormal bladder tissue suspicious of malignancy. However, transurethral resection of a bladder tumor showed no evidence of malignant cells. Amyloid was identified on Congo red staining...
