An immunohistochemical study of nasopharyngeal neoplasms using keratin antibodies
American Journal of Surgical Pathology, 1982Forty cases of nasopharyngeal neoplasia were analyzed using immunohistochemical staining employing keratin antibodies. Using this probe the tumors were classified as being keratin-positive or negative. In this study, all squamous cell carcinomas labeled with keratin antibodies whether they were classified as keratinizing or nonkeratinizing by usual ...

Nasopharyngeal neoplasms and their association with adult onset otitis media with effusion
Clinical Otolaryngology, 1988Patients with adult onset otitis media with effusion are generally subjected to an examination and biopsy of the nasopharynx under a general anaesthetic to exclude a neoplasm of the post-nasal space. The likelihood in Caucasian countries of a tumour being detected has not been clearly defined.

Multiple Malignant Neoplasms in Patients with Nasopharyngeal Carcinoma
Oncology, 1990The records of 759 patients with nasopharyngeal carcinoma were reviewed. Fifteen of them also suffered from another malignant neoplasm. All patients had histological confirmation of the nasopharyngeal carcinoma and the other malignant neoplasm. There was no predilection for the second malignant neoplasms to arise from the bronchus.

Nasopharyngeal Angiofibroma: True Neoplasm or Vascular Malformation?
Advances in Anatomic Pathology, 2000Nasopharyngeal angiofibromas (NA) are rare tumor-like lesions characterized by architecturally irregular vessels set in a fibrous stroma. The unique morphology, the strong predilection for male adolescents, and the uncertainty about its etiology contributes to significant confusion regarding the classification of NA, which still has not been solved ...

Nasopharyngeal and adjacent neoplasms: A clinico-pathologic and immunologic study
Archives of Oto-Rhino-Laryngology, 1978Thirteen cases of nasopharyngeal carcinoma (NPC) and 16 cases of non-NPC tumors in the nasopharynx or in adjacent locations were investigated clinically, immunologically, and pathologically. All tumors were classified according to the TNM classification, and the stage and course of the disease was correlated with the histological tumor type, the T- and

Temporal bone tumours in patients irradiated for nasopharyngeal neoplasm
The Journal of Laryngology & Otology, 1999AbstractRadiation-associated tumours are rare complications of radiotherapy. This study seeks to highlight and discuss the clinically challenging problem of radiation-associated tumours (RATs) in the temporal bones of seven patients previously irradiated for nasopharyngeal neoplasm.Seven patients (six males and one female) with radiation-associated ...

Phenytoin-Induced Lymphadenopathy Appearing as a Nasopharyngeal Malignant Neoplasm
Archives of Otolaryngology - Head and Neck Surgery, 1981A case of phenytoin sodium-induced lymphadenopathy appeared as a nasopharyngeal malignant neoplasm with regional metastases. Cervical lymphadenopathy is a lesser-known drug reaction that is produced by anticonvulsant therapy; under some circumstances, this condition may be confused with head and neck malignant neoplasms.

Most Nasal/Nasopharyngeal Lymphomas are Peripheral T-Cell Neoplasms
The American Journal of Surgical Pathology, 1987Eleven consecutive cases of nasal/nasopharyngeal lymphoma were studied histologically and with a panel of monoclonal antibodies. The disease showed a male predominance and occurred over a wide age range, with a median of 52 years. Five patients had midfacial destructive disease, and six had gross tumor masses involving the nose/nasopharynx. Three cases
