C. Ballestin et al., COMBINED ACINIC CELL AND MUCOEPIDERMOID CARCINOMA OF THE PAROTID-GLAND - REPORT OF A CASE WITH IMMUNOHISTOCHEMICAL STUDY, APMIS. Acta pathologica, microbiologica et immunologica Scandinavica, 104(2), 1996, pp. 99-102
A case where mucoepidermoid and acinic cell carcinoma occurred simulta
neously in the left parotid gland of a 67-year-old man is presented. H
istologically, the neoplasm contained diagnostic areas of these tumors
close to each other within the same tumor mass. A complete immunohist
ochemical study was performed and confirmed the presence of both compo
nents. To the best of our knowledge no similar case has previously bee
n reported.
