[Macroglossia as the initial symptom of amyloidosis].

Amyloidosis is a term that describes a heterogeneous group of disorders in which various tissues contain the characteristic insoluble fibrillar protein known as amyloid. A number of different forms of presentation have been described and include senile, familial or hereditary, systemic, localized, secondary and primary forms. We now report our management of a 79-year old woman who suffered from primary A-lambda-light chain amyloidosis. Amyloid changes first presented in the tissues of the tongue and floor of mouth and were seen clinically as a macroglossia. Further investigation led to a primary diagnosis of multiple myeloma IIa, as categorized by Durie and Salmon. Several cases have been reported to date describing secondary development of macroglossia due to long-term known and treated multiple myeloma. However, there has been only one report of macroglossia as a primary finding leading to the diagnosis of multiple myeloma.
