1/5. Typical carcinoid tumor of the larynx occurring with otalgia: a case report.Neuroendocrine neoplasms of the larynx comprise a rare group of tumors that have a controversial history with regard to their classification. The world health organization categorizes these tumors as typical carcinoids, atypical carcinoids, small-cell neuroendocrine carcinomas, and paragangliomas. Atypical carcinoids and small-cell neuroendocrine carcinomas are the more common. Only 13 cases of typical carcinoid have been reported. Local excision is sufficient for typical carcinoids and paragangliomas, but atypical carcinoids require neck dissection because of their tendency to metastasize. Small-cell neuroendocrine carcinomas are not cured by local excision, and these patients have the worst prognosis (5-year survival: 5%); their treatment is limited to chemo- and radiotherapy. Because of these variations in tumor behavior and treatment, it is essential that otolaryngologists and pathologists to be able to correctly identify the specific type of tumor in order to optimize patient treatment and survival. We report a case of typical carcinoid and review the pertinent literature on this subject.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/5. carcinoid tumor of the middle ear: a case report.Middle ear (ME) carcinoid tumor is exceedingly rare. We present a case of ME carcinoid tumor in a 29-year-old woman whose chief complaints were right otalgia, aural fullness, hearing loss, and facial palsy of 5 days duration. A reddish bulging mass behind the right eardrum and right facial palsy staged as grade IV on the House-Brackmann scale were noted. The high-resolution computed tomography of the temporal bone showed a soft-tissue density mass in the right middle ear and antrum without bony invasion. Although the initial diagnosis was ME adenoma made by the intraoperative frozen section report, the tumor was resected completely by a modified conservative ossicles-preservation method. The patient's initial symptoms of otalgia, aural fullness, and hearing loss immediately improved after surgery, and facial palsy diminished in the following months. No recurrence was noted after 12 months of follow-up.- - - - - - - - - - ranking = 0.084762057362602keywords = soft (Clic here for more details about this article) |
3/5. facial paralysis caused by metastasis of breast carcinoma to the temporal bone.Metastatic tumors to the temporal bone are very rare. The most common sites of origin of temporal bone metastases are breast, lung, kidney, gastrointestinal tract, larynx, prostate gland, and thyroid gland. The pathogenesis of spread to the temporal bone is most commonly by the hematogenous route. The common otologic symptoms that manifest with facial nerve paralysis are often thought to be due to a mastoid infection. Here is a report on a case of breast carcinoma presenting with otalgia, otorrhea, and facial paralysis for 2 months. The patient was initially diagnosed as mastoiditis, and later the clinical impression was revised to metastatic breast carcinoma to temporal bone, based on the pathologic findings. Metastatic disease should be considered as a possible etiology in patients with a clinical history of malignant neoplasms presenting with common otologic or vestibular symptoms, especially with facial nerve paralysis.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
4/5. Middle-ear ceruminous adenoma as a rare cause of hearing loss and vertigo: case reports.Middle-ear ceruminous adenomas are rare benign neoplasms arising from the epithelium of the middle ear. Progressive hearing loss, ear fullness and tinnitus are common symptoms of this tumour; facial nerve paresis and vestibular disturbances occur very infrequently. We present two cases of middle-ear ceruminous adenomas, one showed rapid unilateral hearing loss with aural fullness, followed by purulent aural discharge and vertigo. In the second case, the disease affected an already deaf ear and the only symptom of the disease was increasing vertigo. The clinical features, intraoperative findings, and histological and radiological findings are presented. The cases are compared to those described in the literature.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
5/5. Malignant cylindroma of the external auditory canal.OBJECTIVE: This report describes a case of a malignant cylindroma arising in the external auditory canal. STUDY DESIGN: Retrospective surgical case review. SETTING: Tertiary care teaching hospital. INTERVENTION: Wide local excision with margin control. RESULTS: Local control of disease at 2-year follow-up. CONCLUSION: To our knowledge, this is the first report describing a malignant degeneration of cylindroma in the external auditory canal. This tumor represents an extremely rare cutaneous neoplasm, thus raising diagnostic and therapeutic challenges.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
