摘要:

AbstractThe occurrence of metastatic tumors in the tonsils, although rare, must be considered in the differential diagnosis of tonsillar lesions. In particular, the review of the literature reports only 7 cases of tonsillar metastasis of gastric carcinoma. The authors describe a case of adenocarcinoma involving bilaterally the palatine tonsils and the lingual tonsil, in a patient previously operated due to gastric adenocarcinoma. The clinical appearance of the lesion could be also consistent with lymphoproliferative or infectious diseases. The clinical and pathologic differential diagnosis of this peculiar case is discussed, together with a brief review of the literature.

摘要:

AbstractPleomorphic adenoma of the palate is a rare entity in childhood. Only 4 cases of this lesion are documented in detail in the literature. We present a patient with this lesion and discuss the usefulness of magnetic resonance imaging (MRI) in the preoperative evaluation. A review of the previously reported cases is provided along with a discussion of the treatment of this lesion.

摘要:

AbstractUpper aerodigestive tract (UADT) cancers provide an excellent carcinogenesis model for a number of reasons: they are accessible to observation, are usually associated with a known environmental carcinogen (tobacco by‐products), are sometimes associated with a tumorigenic DNA virus (HPV), and fall along a spectrum of progressive disease from normal mucosa through leukoplakia and verrucous carcinoma to invasive and metastatic carcinoma. Despite the presence of this unique model, the field of head and neck oncology, as a whole, has been slow in establishing an efficient 2‐way conduit between the bedside and the laboratory. Such open communication is important as current evidence suggests that future staging and therapy of head and neck tumors will depend not only on familiar macroscopic and light microscopic criteria, but also on factors that are currently identifiable only in the basic science laboratory. To have a significant impact on the direction and relevance of basic research, clinicians should become knowledgeable and conversant in the vocabulary and general concepts of basic science. The goal of this section is to facilitate communication between the basic researcher and the clinician, thereby promoting clinically relevant basic research. This is to be achieved by fostering understanding of the power, limitations, scope, and horizons of current basic research concepts and techniques. Subsequent articles will review current research topics germane to head and neck cancer, such as oncogenes and tumor suppressor genes, mechanisms of metastasis, tumor immunology and its modulation, and virology.
