1/861. Laryngeal pathology in the acquired immunodeficiency syndrome: diagnostic and therapeutic dilemmas.The acquired immunodeficiency syndrome has produced a growing population of patients who, because of their associated immune system compromise, are prone to opportunistic infections and neoplastic diseases. The larynx, with its relatively inaccessible yet critical anatomic location, is a site in which these processes can produce clinical dilemmas, with respect to diagnosis as well as to therapy. By presenting 4 cases involving unusual laryngeal problems in patients infected with the human immunodeficiency virus (hiv), we emphasize these inherent diagnostic and therapeutic problems. Otolaryngologists must be familiar with the many diagnostic possibilities and therapeutic alternatives when hiv-infected patients present with laryngeal complaints.- - - - - - - - - - ranking = 1keywords = larynx (Clic here for more details about this article) |
2/861. rhabdomyoma of the hypopharynx and larynx. Report of two cases and a review of the literature.Two cases of extracardiac rhabdomyoma are reported in a 54-year-old man with unexplained difficulty in breathing and in a 39-year-old man with a prolonged history of hoarseness. attention is drawn to the necessity of doing hypopharyngo-and laryngoscopy in such cases. One tumour was found in the left vallecula in the hypopharynx and the other on the left vocal cord. The literature and the histological findings in 53 cases are reviewed. It appears that this rare tumour is most frequently found in muscles derived from the pharyngeal arches. A total of 40 cases have been diagnosed during the last decade, and this increase is likely to continue in the future. It may turn out that extra-cardiac rhabdomyoma is not so rare as was first presumed.- - - - - - - - - - ranking = 4keywords = larynx (Clic here for more details about this article) |
3/861. Primary anaplastic giant cell adenocarcinoma of the larynx.Anaplastic giant cell adenocarcinoma is an extremely rare tumour arising in the bronchial mucosa. This report describes an example--the first to be reported--of such a tumour evidenced in the subglottic region in a 64-year-old man. Histologically, the tumour resembles that arising in the lung and its morphological characteristics justify a distinction of anaplastic giant cell adenocarcinoma from other types of laryngeal malignant epithelial tumours. As to its histogenesis, the neoplasm is most probably of glandular origin and should be considered as a dedifferentiated adenocarcinoma. The patient, who had undergone total laryngectomy followed by X-ray treatment, is alive one year after surgery.- - - - - - - - - - ranking = 4keywords = larynx (Clic here for more details about this article) |
4/861. A pathologic and clinical study of adenosquamous carcinoma of the larynx. Report of four cases and review of the literature.Four cases of adenosquamous carcinoma are described. Emphasis is put on the rarity of this histological type of tumour which was first described in the larynx by Gerughty et al. (1968) who reported three cases. An exhaustive histological documentation of the neoplasm accompanies the discussion of its pathomorphological characteristics, histogenesis, differential diagnosis, prognosis and treatment. Stress is laid on the extreme aggressiveness of the neoplasm and on its high biologic malignancy. Elective treatment is radical surgery. The tumour in question is a distinct anatomo-clinical entity with its own connotations and therefore must be distinguished from the most common squamous cell carcinoma of the larynx.- - - - - - - - - - ranking = 6keywords = larynx (Clic here for more details about this article) |
5/861. Giant lipoma of the larynx: a case report and literature review.Fewer than 15% of lipomas occur in the head and neck. To date, fewer than 100 cases of laryngeal lipoma have been reported in the literature. Typical clinical manifestations include dysphagia, dyspnea and hoarseness, as well as the presence of a smooth or pedunculated mass seen endoscopically and a low attenuation mass on computed tomography scan. Pathologic sections commonly reveal a tumor consisting of mature adipocytes, which is often encapsulated. Treatment of laryngeal lipoma varies from conservative total endoscopic removal to external surgical approaches. The following is a report of a single case of laryngeal lipoma, including pathologic and radiologic findings, as well as a review of the literature.- - - - - - - - - - ranking = 4keywords = larynx (Clic here for more details about this article) |
6/861. Desmoid tumor of the larynx complicating pregnancy: a case report.Desmoid tumors are locally invasive fibrous neoplasms that arise from musculoaponeurotic structures. We report the first case of a desmoid tumor of the larynx complicating pregnancy. At 21 weeks' gestation fiberoptic and indirect otolaryngologic examination of the patient's larynx revealed a submucosal tumor involving the left true vocal cord, ventricle of the larynx, and false vocal cord. Histopathologic examination revealed areas of extensive fibrosis intermixed with degenerated vocal cord skeletal muscle. Despite a subtotal excisional biopsy, growth of the desmoid tumor continued during pregnancy. Endoscopic evaluation 9 weeks post partum revealed complete regression of the tumor.- - - - - - - - - - ranking = 7keywords = larynx (Clic here for more details about this article) |
7/861. Fibrous histiocytoma of the larynx.We present a case of fibrous histiocytoma of the larynx in a young female who presented eight years ago and is still alive and well with no evidence of any regional invasion or distant metastasis. This rare lesion has been described in 30 cases previously of which 26 were malignant and four benign. Our case is unusual in a sense that histologically it has not been possible to determine its exact biological behaviour and growth potential. However, clinically it behaved as a low-grade malignant tumour.- - - - - - - - - - ranking = 5keywords = larynx (Clic here for more details about this article) |
8/861. chondrosarcoma of larynx: a case successfully reconstructed after total cricoidectomy.A case of a 64-year-old male with low-grade chondrosarcoma of the left posterolateral lamina of the cricoid cartilage is reported, in which a total cricoidectomy and partial resection of the left thyroid cartilage were performed. The rest of the thyroid cartilage and the arytenoid mucosa were approximated with sutures to the first tracheal ring, and a silastic T-tube was placed through the tracheostoma as a stent. The postoperative course has been successful except for the existence of a tracheal stoma and slight hoarseness. There has been no evidence of laryngeal stenosis nor recurrence at about 9 years postoperatively.- - - - - - - - - - ranking = 4keywords = larynx (Clic here for more details about this article) |
9/861. Primary cancer of the larynx associated with primary lung cancer. Report of 21 cases, 14 with autopsy findings and 7 biopsies.The present paper reports 21 cases (14 autopsies and 7 biopsies) of associated primary cancers of the larynx and the lung. This association is by no means uncommon, the laryngeal lesion being usually the first to appear. Mulitple primary cancers--of the same or of a different histologic type--tend to occur in the same organ or organ system, either simultaneously or after a time interval. In case of synchronous primary malignant tumour of the larynx and lung the most lethal cancer (the lung cancer) must be managed first. Cancer patients are more likely than other individuals to develop a second primary malignant tumour. Laryngectomized patients should be followed-up possibly by means of cytologic examinations of bronchial secretions and chest x-rays at short intervals for early detection of a possible second primary malignant pulmonary lesion.- - - - - - - - - - ranking = 6keywords = larynx (Clic here for more details about this article) |
10/861. Solitary plasmacytoma of the larynx and upper trachea associated with systemic lupus erythematosus.Solitary plasmacytoma rarely involves the larynx and trachea. This tumor caused severe laryngeal and tracheal obstruction in an adolescent female with systemic lupus erythematosus of nine years' duration. Her systemic disease had been in remission at the time she developed symptoms of laryngeal and tracheal obstruction by plasmacytoma invasion. A complete survey failed to reveal any other focus of tumor. Because steroid therapy failed to clear the plasma cell infiltrate, she was treated with irradiation after the tumor was surgically debulked endoscopically. Postirradiation biopsy showed no evidence of tumor, but the patient continued to experience moderate airway obstruction from fibrosis in the irradiated trachea. The patient has been followed, and is free of disease nine years after establishing the diagnosis.- - - - - - - - - - ranking = 5keywords = larynx (Clic here for more details about this article) |
