摘要:

AbstractA staging system for juvenile angiofibroma based on computerized tomographic findings is suggested. The need for such an endeavor has come about because of a lack of standardization of tumor data in both individual series and interinstitutional reports. The various stages reflect the number of anatomic sites occupied by a lesion rather than the actual tumor size. The “simpler” tumors are confined to the medial part of the skull base and are entirely extracranial. As a tumor extends laterally and/or intracranially, the staging designation, and therefore the treatment plan, changes accordingly. Presumably, with the application of consistent diagnostic tools and standardized stage designations, the analysis of both morbidity and treatment data will become more meaning

摘要:

AbstractRecent interest in the application of computed tomography (CT) to the evaluation of laryngeal tumors, and the fact that the larynx offers the unique opportunity of whole organ study after total laryngectomy, led to a prospective study of laryngoscopy, conventional tomography, and CT in relation to pathologic findings. The results showed that CT gives an exact assessment of laryngeal anatomy and tumor involvement, particularly in the paracordal and pre‐epiglottic spaces. The laryngeal cartilages, which are not well demonstrated by any other means, are accurately delineated by CT. There is also good demonstration of the laryngeal surface of the epiglottis, including the anterior commissure, which is poorly shown by other radiologic methods and is sometimes poorly seen on laryngoscopy. Because CT and conventional tomography present images at 2 different planes, at right angles to each other, we believe that CT is entirely complementary to conventional tomograph

摘要:

AbstractFor the differentiation of benign from malignant thyroidal disease, ultrasound displays anatomic but not histologic features. Other visualization techniques can be used including isotope scanning (radioiodine,99mtechnetium,241americium fluorescence,131cesium,67gallium,75selenomethionine,201thallium,32phosphorus,99mTc‐bleomycin,197mercury,133xenon), thermography, x‐ray techniques (plain films, computed tomographic scan, xeroradiography, chest x‐ray, barium swallow, lymphography, angiography), and thyroid hormone suppression. Needle biopsy can be done by core biopsy (Vim‐Silverman and drill biopsy), large needle biopsy for histologic processing and fine needle aspiration for cytologic interpretation. The latter is the safest, most reliable, and most cost‐effective technique currently available to differentiate between benign and malignant thyroidal disease and has great promise for t

摘要:

AbstractThere are three principal malignant vasoformative tumors that can be found in the head and neck—hemangiopericytoma, angiosarcoma, and Kaposi's sarcoma. All are uncommon and provide challenges for the pathologist and the therapist both. The histogenesis of each tumor is different. Kaposi's sarcoma has many features which suggest that it is an altered immune‐response disease. Angiosarcoma is a malignancy of endothelium. Hemangiopericytoma is a tumor whose cell of origin is considered to be the perithelial pericyte. The general prognosis for patients with Kaposi's sarcoma is good. The biologic course of a hemangiopericytoma is variable and unpredictable, but there appears to be a site dependency. Angiosarcomas, particularly high grade lesions, are resistant to ther

摘要:

AbstractIn recent years, the management of parotid gland neoplasms has changed considerably, to include a more aggressive surgical approach and multimodality therapy. An organized approach to surgical management and the rationale for postoperative irradiation for selected tumors are presented. A review of several studies supporting the efficacy of postoperative irradiation is included. The principles of palliative management of adenoidcystic carcinoma are unlike those for most other malignancies, and include repeated use of limited procedures to control local and regional disease over extended periods of time, and delayed treatment of distant disease until the patient becomes symptomatic.
