Peripheral facial paralysis from tumoral origin is scarce in number, in spite of possible manifold causative growths. One case in which the palsy was associated to a rhinopharyngeal neoplasm is reported and possible ways of nerve involvement discussed. Although progression seems to be the most probable hypothesis in this instance, only the anatomo-pathological exam has affirmative value.
A 43-year-old female patient complaining with odynophagy since a month and a half without response to the medical treatment is presented. The pharynx exam showed an asymmetric swelling in the right tonsillar surface and the radiology provided evidence of calcareous concretions as responsible cause of the picture.
A 43 year-old man with a cystic mass on the side of the neck was admitted to the hospital for possible branchial cyst. The histopathological analysis showed a carcinoma developed on a branchial cyst. After reviewing the literature, we conclude that carcinoma developing on a branchial cyst is uncommon, if, indeed, it exists at all. The diagnostic criteria should be adhered to strictly. When confronted with this histopathologic diagnosis, the possibility of cystic metastasis to the neck of a squamous carcinoma of unknown origin should be considered.
Differentiating between Wegener's granulomatosis and other destructive centrofacial lesions often is difficult for clinicians and pathologists. It has become more confusing since what until now was known as "malignant centrofacial granulomatosis" seems to be a peripheral T-cell lymphoma. The case of an 83-year-old male recently diagnosed as angiocentric peripheral T-cell lymphoma which presented as a destructive centrofacial process is reported. The probable pathogenic role of Epstein-Barr virus (EBV) is highlighted.
