A rare cause of AA amyloidosis: Glomus tumor and treatment with anakinra—Case report and literature review

Abstract

AbstractSystemic AA amyloidosis is associated with poorly controlled chronic inflammatory disorders. Chronic infections and inflammatory arthritis are the most common causes; however, they can also rarely occur as a complication of neoplastic disorders. The development of AA amyloidosis secondary to paraganglioma, which is a rare type of tumor, has rarely been reported in the literature. In this case, an 85‐year‐old female patient with a glomus tumor in the neck, who has been followed up over 50 years, applied with complaints of loss of appetite, nausea, and diarrhea for 5–6 months. While evaluating the patient, who had high levels of acute phase reactants, amyloidosis was diagnosed by salivary gland biopsy. No other cause was found to explain amyloidosis. The patient, who could not tolerate treatment with colchicine and azathioprine, is successfully treated with the interleukin‐1 inhibitor anakinra. A rare relationship, systemic AA amyloidosis, which is thought to have developed as a result of long‐standing jugular paraganglioma, is presented in this article. In addition, publications showing an association between paragangliomas and amyloidosis were reviewed.
