Macroglossia reveals multiple myeloma

Abstract

We present an eighty-year old man with a one year history of progressive macroglossia, dysphagia and loss of weight. He had a medical history of arterial hypertension and prostatic hypertrophy which he had under good therapeutic control. The entire tongue was swollen, had hard solidity and was slightly painful upon palpation. A tongue biopsy revealed an amyloid deposition as it coloured bright orange-red on Congo Red staining and lead us subsequently to the diagnosis of amyloidosis; then a bone marrow biopsy confirmed the diagnosis of multiple myeloma. The case was further evaluated by a multidisciplinary team who considered it appropriate to start a lowdose melphalan treatment combined with supportive care. When macroglossia in the tongue is confirmed to be amyloidosis the differential diagnosis should include systemic amyloidosis deposition and multiple myeloma.
