Neoplasms of the Hard Palate

Epidemiological Evaluation of Palatal Cancers in Iran: A Study on 303 Cases

“…In our series, AdCC and MEC were the commonest malignancies of salivary gland origin (77.6%) followed by adenocarcinoma NOS (8.4%) and PLGA (5.6%). Similar to the findings of this research, several studies reported that (AdCC) and (MEC) were the most common salivary gland carcinoma of palatal region (1,8,12,16). In salivary gland carcinomas, the peak incidence was in the 4th to 7th decade almost equally.…”

“…In the current study, 56.43% of palatal cancers occurred in men and 43.56% in women (ratio: 1.29). In a study conducted by Aydil et al (1), no sex predilection was evident. It is well-known that the commonest oral cancer is SCC (2, 11), but It is noteworthy to refer to Duzlu et al (2) who found that a large number of SCC was detected in all sub-sites of the oral cavity except the hard palate.…”

“…The male to female ratio was 1.39 and the peak incidence was in the 6th to 8th decades of life. Aydil et al (1) also found that SCC is the second malignancy after salivary gland tumors in palate. Oral melanoma is rare and it accounts for only 0.5% of all oral malignancies, but palatal mucosa is the commonest location and there is a male predilection with the mean age of 65 years (25).…”

“…SCC, melanoma, lymphoma, and sarcoma comprised 28.5%, 14.2%, 7%, and 7% of the malignancies in their series, respectively. Palate is the most common site for minor salivary gland tumor (1,11,12). Salivary gland neoplasms depict a heterogeneous group of tumors, with a broad range of microscopic types (13)(14)(15).…”

“…Therefore, palatal neoplasms may demonstrate different microscopic features compared with other anatomic area of the oral cavity (1). Several studies in the literature, including whole oral cavity, have made it difficult to assess their actual frequency of palatal malignancies (2)(3)(4)(5)(6).…”
