In a few cases, immunoglobulin chain amyloidosis fibrils contain only heavy-chain sequences rather than light-chain sequences, and the disease is termed AH rather than AL. Electron microscopy may be helpful in the detection of small deposits and in the differentiation of amyloid from other types of renal fibrillar deposits. [43]
