Figure 1: (A) Photograph of a 52-year-old man with insulin-derived amyloidosis, showing discoloration (arrows) on his right and left upper abdomen, overlying 2 palpable nodules. (B) A computed tomography scan of the abdomen showing bilateral, irregularly shaped, dense lesions on the bilateral anterior abdominal wall at the site of insulin injection (arrows), with no surrounding inflammatory change, consistent with subcutaneous amyloid deposits. The posterior lateral margins of the mass are ill-defined, and the average density of the lesions is 53 Hounsfield units with minimal enhancement.
