Review of the literature and our personal experience with carcinoma of the palate indicates that a significant number of patients may benefit from palatal resection, either as an initial modality, in a planned combined treatment program, or for salvage after radiation therapy. Under any of these circumstances an integral part of the treatment program is rehabilitation of speech and swallowing function through prosthetic repair. Familiarity with the potentials and techniques of prosthetic rehabilitation after palatal resection is an important concern for the head and neck oncologist.

BACKGROUND: This case report describes a unique palatal tumor with features of a dermal neoplasm. Microscopically, the lesion appeared similar to a trichoepithelioma and trichoadenoma. METHODS: Light microscopic and immunohistochemical studies were performed to arrive at the final diagnosis. RESULTS: The lesion arose from the surface epithelium and had features of a dermal tumor. CONCLUSIONS: The case report describes a unique benign palatal neoplasm.

Soft palate neoplasms are relatively rare and their care requires not only an adequate surgical removal but also a post-treatment rehabilitation. In this article the authors after having considered the importance of the soft palate function on the individual's ability to shallow and speak, describe one case of squamous cell carcinoma of the soft palate and treated with surgery followed by prosthetic rehabilitation. Especially it is pointed out the utility of a palatal obturator in the care of deleterious esthetic and psychological aspect of the residual anatomical defect, considering the possibility of the re-establishment the integrity of the tissues and structures in the oral cavity by hand-made prosthesis more and more exact and functional.
A retrospective study of 103 cases of metastatic pulmonary tumors originated from oral and maxillofacial regions was made radiologically as well as clinically. With regard to the site and pathologic type of the primary neoplasm, palatal tumor and adenoid cystic carcinoma was the most frequent ones respectively which metastasize to the lungs. Radiologic types of metastatic pulmonary tumor might be classified into five categories: solitary, multiple nodular, multiple mass, diffuse and miliary network. The relationship between prognosis and radiologic types, the growing rate and complications such as cavitation, atelectasis, pleural effusion, lymph node enlargement and destruction of ribs were briefly discussed. The authors were of the opinion that the duration from primary to metastatic and that from metastases to death in oral and maxillofacial malignant tumors are longer than those of other sites in human body.
