A case of cutaneous nodular amyloidosis in a 60-year-old man is described with reference to histological, immunohistochemical and ultrastructural features. Clinically, the patient presented two brownish nodules on his face. Histologically, a massive dermal collection of eosinophilic, homogeneous material showing positivity for Congo red stain was revealed. Immunoreactivity for both Ig-light chains was detected in dermal plasma cells as well as in amyloid material. Ultramicroscopically, the typical fibrillary pattern of amyloid was found. Clinical and instrumental examinations failed to demonstrate amyloid depositions elsewhere in the body.

UI MeSH Term Description Entries
D007147 Immunoglobulin Light Chains Polypeptide chains, consisting of 211 to 217 amino acid residues and having a molecular weight of approximately 22 kDa. There are two major types of light chains, kappa and lambda. Two Ig light chains and two Ig heavy chains (IMMUNOGLOBULIN HEAVY CHAINS) make one immunoglobulin molecule.

D000682 Amyloid A fibrous protein complex that consists of proteins folded into a specific cross beta-pleated sheet structure. This fibrillar structure has been found as an alternative folding pattern for a variety of functional proteins. Deposits of amyloid in the form of AMYLOID PLAQUES are associated with a variety of degenerative diseases. The amyloid structure has also been found in a number of functional proteins that are unrelated to disease.

D000686 Amyloidosis A group of sporadic, familial and/or inherited, degenerative, and infectious disease processes, linked by the common theme of abnormal protein folding and deposition of AMYLOID. As the amyloid deposits enlarge they displace normal tissue structures, causing disruption of function. Various signs and symptoms depend on the location and size of the deposits. Amyloidoses
