Summary We have presented the survival rates of patients with cancer of the head and neck treated with radiation therapy, surgery, and Hydroxyurea. The survival of patients receiving Hydroxyurea was significantly higher, suggesting that the chemical may possess a cytotoxic or radiosensitizing effect useful as an adjunct to radiation therapy and ...

Unusual Neoplasms of the Head and Neck [PDF]

, 2010
Chloromas (also called granulocytic sarcomas or myeloid sarcomas) are solid extramedullary tumors consisting of early myeloid precursors associated with AML. The name derives from the green color of affected tissues. They are more frequent with AML M4 and M5 subtypes, and are associated with t(8;21). They may herald AML relapse after remission.

Neoplasms of the head and neck

Oral Surgery, Oral Medicine, Oral Pathology, 1948
Abstract Most early cancers of the head and neck are not difficult to diagnose, especially those of the skin, lips, and oral cavity. They are usually accessible to examination, and even some of the more obscure may be detected by palpation. In this respect, the dentist is in an enviable position to detect and recognize early neoplasms.

Neoplasms of the Head and Neck [PDF]

, 2013
Neoplasms of the head and neck in children are different from those of adult population in frequency and pathology. The most benign tumor in children is infantile hemangioma. Other common benign tumors and tumor-like lesions include teratoma, nasopharyngeal angiofibroma, Langerhans cell histiocytosis (LCH), and soft tissue tumors (fibromatosis colli ...

Unusual presentation of head and neck neoplasm

The Laryngoscope, 1982
AbstractWe have a 67‐year‐old Caucasian male presenting with a (T4, N1b, M0) Stage III squamous cell carcinoma of the larynx. He subsequently underwent a total laryngectomy and right radical neck dissection. It was only determined by the pathology report that the cervical nodes in the neck specimen obtained the associated disease, Hodgkin's (mixed ...
