Mucoepidermoid carcinoma (MEC) accounts for approximately 30% of malignant salivary gland tumors and approximately
30% occur in minor salivary glands. The palate is the most frequent localization for those arising in minor
glands. A 33-year-old male patient with MEC of the hard palate was treated as an acute odontogenic infection, which
was not cured after tooth endodontic treatments, repeated incisions and antibiotics. On the hard palate ovoid, a hard
painless mass, which had not extended over the middle palatal line, was observed. Partial maxillectomy was performed.
A review of the literature was performed in order to provide a coherent overview on the differential diagnosis of palatal
lesions. To the best of authors’ knowledge, this is the first report in English literature describing palatal MEC misdiagnosed
and treated as odontogenic infection. Considering the extensive list of MEC’s differential diagnoses on the
hard palate, acute odontogenic infection can now be added to that list.

Salivary gland tumors constitute a highly heterogeneous histopathologic group. There are few epidemiological studies of large series of benign and malignant salivary gland tumors in Brazil. MATERIAL AND METHODS: Hospital records of 124 patients with salivary gland tumors diagnosed from January 1993 to December 1999 were reviewed. The patients were analyzed according to gender, age, size, location, and histopathology of the tumor. RESULTS AND CONCLUSIONS: Patients with benign and malignant tumors presented with a mean age of 47.7 and 48.8 years, respectively. The frequency of benign tumors was 80% (n = 99) and malignant tumors 20% (n = 25). Tumors were localized in the parotid gland 71% (n = 88), in the submandibular gland 24% (n = 30), and in the minor salivary glands 5% (n = 6). The most common benign tumors were pleomorphic adenoma in 84% (n = 84) and Warthin's tumor in 13% (n = 13). Among malignant tumors, mucoepidermoid carcinoma was the most common in 52% (n = 13), adenoid ...
