Secondary cutaneous nodular AA amyloidosis in a patient with primary Sjogren syndrome and celiac disease.

摘要

We describe a 62-year-old female with primary Sjogren syndrome and myopathy, severe osteoporosis, and vertebral fractures that were attributed to celiac disease. A year after the diagnosis, she developed a skin nodule on the extensor surface of her right elbow, which was due to an amyloid deposit of AA type. Amyloidosis, although relatively common in some chronic inflammatory diseases, has been uncommon in Sjogren syndrome or celiac disease. Visceral amyloid was not found in this patient.
