Nasopharyngeal neuroendocrine neoplasms: Systematic review of the literature and case presentation

open access: closedJournal of Neuroendocrinology, 2021
Abstract Most of neuroendocrine neoplasms (NENs) are located in the gastrointestinal tract and lung, and they are rarely found on the upper aero‐digestive tract, which limit the current literature about nasopharyngeal NENs. This systemic review will summarize the clinical, pathological features and optimal diagnosis and management of ...

Most Nasal/Nasopharyngeal Lymphomas are Peripheral T-Cell Neoplasms

open access: closedThe American Journal of Surgical Pathology, 1987
Eleven 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

Nasopharyngeal and adjacent neoplasms: A clinico-pathologic and immunologic study

open access: closedArchives of Oto-Rhino-Laryngology, 1978
Thirteen 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

Nasopharyngeal Angiofibroma: True Neoplasm or Vascular Malformation?

Advances in Anatomic Pathology, 2000
Nasopharyngeal 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 ...

Multiple Malignant Neoplasms in Patients with Nasopharyngeal Carcinoma

Oncology, 1990
The 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.

An immunohistochemical study of nasopharyngeal neoplasms using keratin antibodies

The American Journal of Surgical Pathology, 1982
Forty 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 ...

Temporal bone tumours in patients irradiated for nasopharyngeal neoplasm

The Journal of Laryngology & Otology, 1999
AbstractRadiation-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 ...
