Abstract:
A 65-year old woman presented with nasal obstruction and on examination was found to have a huge mass in the maxillary sinus. This was removed, and histological examination revealed a mixture of trabecular structures consisting of inner dark cells, outer clear cells and solid structures consisting of only clear cells. Immunohistochemical examination showed the clear cells to be positive for α-smooth muscle actin. Ultrastructural examination confirmed the myoepithelial cell origin. The characteristic morphological, immunohistochemical and ultrastructural features aided in the diagnosis of epithelial-myoepithelial carcinoma.
