Bone marrow biopsy and fat aspirate was positive for amyloid by Congo red staining. There were < 7% plasma cells in the bone marrow biopsy, and clonality was not established. Plasma cell labeling ...

Diagnosis of amyloidosis traditionally relies on the identification of amyloid in tissue samples. Conventional biopsy techniques, however, including rectal biopsy, are invasive and associated with ...

Following a liver biopsy at Loyola University Medical Center, 69-year-old John Nyhoff was diagnosed with amyloid light-chain (AL) amyloidosis, a rare, often misdiagnosed, blood cancer.

Of these, 5 had renal biopsy–confirmed renal AL amyloidosis, and 1 had LCDD. All 5 patients with AL amyloidosis had λ Bence Jones proteinuria. The only patient in our study with renal LCDD had ...

the sensitivity of fat pad biopsy for detection of AL cardiac amyloidosis is acceptable (84%) but is much lower for TTR (45% for heritable; 15% for wild-type). In addition, several noninvasive ...

Satoskar and co-workers have analyzed 15 renal biopsy samples and used their results to illustrate some of the potential problems in classification of renal amyloidosis. AL amyloidosis is ...
