Lymphoepithelioma-like carcinoma (LELC), best known to occur in the nasopharynx, can arise in a variety of sites, such as the salivary gland, thymus, lung, stomach, and skin. Primary LELC of the lung is very rare, with only limited information in the literature. We presented a case of a 66-year-old white man with a T2N0M0 lymphoepithelioma-like carcinoma of the lung. Immunohistochemical analysi...
Inverted Papilloma (IP) is an uncommon benign sinonasal neoplasm of a particular interest because of its capacity to recur and undergo malignant transformation. It affects usually the lateral nasal wall, but rarely develops in the nasopharynx. We report a case of a well-defined polypoidal lesion of the nasopharynx presented with decreased hearing secondary to unilateral middle ear effusion. It ...
Warthin tumor is the second most frequent benign salivary gland tumor after pleomorphic adenoma; it occurs almost exclusively in the parotid gland and peri-parotideal lymph nodes, although it may rarely present in other locations. It may be multicentric and bilateral in a small percentage of cases. Nasopharyngeal Warthin tumor is very rare, and the presence of a synchronic WT involving nasophar...
Sortase A (SrtA) is required to anchor neuraminidase, beta-galactosidase, and possibly other LPXTG motif proteins to the pneumococcal cell surface. We examined the role of SrtA in Streptococcus pneumoniae nasopharyngeal (NP) colonization in the chinchilla model. The srtA mutant colonized the nasopharynx at a significantly lower level than the D39 parent strain during the second and third week o...
Lymphoepithelial carcinoma is an undifferentiated nasopharyngeal carcinoma with lymphoid stroma and non-keratinizing squamous cells with distinctive clinical, epidemiological and etiological features. Conversely, lymphoepithelioma-like carcinomas (LELCs) are carcinomas that arise outside the nasopharynx but resemble a lymphoepithelioma histologically. In this case study, LELC presentation in co...
During 1971 and 1972, 71 cultures of neisseriae that attacked lactose were received by this laboratory. All strains except one from an eye swab were from the nasopharynx of healthy subjects. Nineteen similar strains from the nasopharynx were isolated in this laboratory. The characteristics of these strains were compared with those of Neisseria meningitidis, Neisseria pharyngis, Neisseria catarr...
The maxillary swing approach (MSA) allows access to the retromaxillary area, pterygopalatine fossa, nasopharynx and infratemporal fossa through temporary disarticulation lateral of maxilla with attached facial skin. We report a case resection tumor occupying wide area sinus using modified MSA.
