Abstract
|
|
|
Laryngeal amyloidosis is a rare disorder characterized by localized amyloid deposition andcarries an excellent prognosis. On the other hand, mucosa associated lymphoid tissue (MALT)lymphoma is the most common type of marginal zone lymphoma. MALT lymphoma has apoorer prognosis compared to laryngeal amyloidosis due to more frequent local recurrence,distant metastasis and malignant changes. Despite the differences, as both are found in theform of benign mass and have slow progression, accurate diagnosis is necessary. This reportdeals with the case of a patient with voice change accompanied by a mass, in which the initialbiopsy did not include enough specimen for an accurate diagnosis. However, in the second attempt,an adequate sample was obtained, hence the final diagnosis of laryngeal MALT lymphoma.
Based on our recent experience and a review of related literature, we report a case oflaryngeal MALT lymphoma mimicking laryngeal amyloidosis.
