Previously classified as a congenital pleomorphic adenoma by Har-El et al,1 these lesions were definitively characterized by Dehner et al,2 who described a series of 9 patients in 1994. A total of 23 cases have been reported in the literature to date.1-9 The histologic appearance of SGAT is characterized by fusiform, epithelioid proliferations that merge with ductal and glandular structures that are often lined by cuboidal, "basaloid" cells. These internal structures are focally continuous with the squamous mucosa of the tumor's surface.4 Similar structural organization and cellular composition are evident during the embryological development of salivary glands when the ectoderm or endoderm proliferates into the underlying mesenchyme.2 Debate regarding whether SGAT is a hamartoma or a true neoplasm remains unresolved.
