One case of primary adenocarcinoma of the middle ear is reported, which developed from a chronic otitis media. Histological examination established the diagnosis of adenocarcinoma. Its clinical appearance was benign, being restricted to the middle ear and tympanic membrane and with no bone destruction or metastases. Two years after local surgery there was no evidence of recurrence. 相似文献

We present a case of a 52-year-old white female with what we believe is the first documented example of a primary melanoma of the middle ear. Multiple myringotomies and two tube insertions over a 14-month period were curried out until frank hemorrhage was encountered on the last one. Middle ear exploration found the lesion to be a primary melanoma. The supposed course of her diseased ear is discussed as regards the lag between effusion and frank blood when tumor was finally hit on the last myringotomy. 相似文献

Schwannomas of the middle ear may originate from the nerves of the middle ear cavity or by extensions from neighboring structures. We present a case of a 51-year-old female patient with primary middle ear schwannoma believed to arise from Jacobson's nerve. The tumor was easily divided from the facial nerve and the chorda tympani nerve. Erosion of the promontory was noted, and the jugular foramen and posterior wall of the ear canal were preserved without destruction. The mass was successfully removed by a canal down mastoidectomy procedure, while preserving the hearing and facial nerve functions of the patient. To our knowledge, this is only the second reported case of a patient with Jacobson's nerve schwannoma. 相似文献

The benign, monomorphic adenoma, derived from the respiratory epithelium of the middle ear, is a well circumscribed, greyish, avascular tumor. Its histology — documented by light and electron micrographs contained in this report — supports a distinct entity and pathogenesis apart from the malignant adenocarcinoma. Utilizing two case reports, this compendium emphasizes the clinical presentations, as well as radiographic and audiometrical characteristics, of the tumor. The first case represents the typical tumor with conductive hearing loss. The second case is the first reported facial paralysis associated with hemorrhagic infarction of an adenoma which was reversible by surgical resection of the tumor. Based on the histology and four year postoperative follow-up, the authors conclude the adenoma may be effectively managed by surgical resection. 相似文献

Primary adenocarcinoma of the middle ear is rare. It may or may not be associated with chronic suppurative otitis media. After the exclusion of a primary site elsewhere, the tumor should be managed by surgery and postoperative radiotherapy, especially if tumor excision is incomplete. We report a case in which primary papillary adenocarcinoma developed in the middle ear, possibly due to aberrant ceruminous gland elements. The findings prior to histologic examination were unusual in that they were consistent with a tumor of the glomus tympanicum or glomus jugulare. 相似文献

Two patients with primary adenocarcinoma of the middle ear displayed symptoms in the affected ear many years before their condition was diagnosed as adenocarcinoma. Treatment included simple extirpation of the tumor, radical mastoidectomy with or without radiation. A review of the literature shows 11 cases reported previously. Follow-up of the patients for more than four years revealed four deaths in the reported cases-one from causes unrelated to the tumor and the others showing only local invasion without distant metastases. These tumors grow slowly and have a low-grade of malignancy. 相似文献

Adenomatous lesions of the temporal bone are seldom encountered in clinical practice. Four cases of primary adenocarcinoma of the middle ear are reported. All four patients presented with a mass behind an intact tympanic membrane. Two of the four patients had received radiation to the head and neck area 10 or more years prior to their developing adenocarcinoma of the middle ear space. Although this tumor is locally invasive, it does not appear to be highly aggressive and can be treated by local excision, i.e., mastoidectomy with tympanoplasty. 相似文献

The middle ear cavity and the eustachian tube contain a well-functioning mucociliary clearance system. To learn more about the importance of this mucociliary clearance, we studied patients with primary ciliary dyskinesia, in whom mucociliary clearance is absent. Thirty-six patients were investigated by means of a questionnaire; in 16 of these patients, otological and audiological studies could be performed. In patients with primary ciliary dyskinesia, a discrepancy was found between subjective ear complaints and the actual middle ear function. Moreover, it appeared that for the middle ear system, mucociliary clearance is of importance only in the first 3 decades of life. With aging, however, a deficient mucociliary clearance system in the middle ear and eustachian tube can be fully compensated for. 相似文献

Primary mucosal malignant melanoma of the middle ear. 总被引:1,自引:0,他引:1
Only one case of primary malignant melanoma of the middle ear has been reported in the literature to date. We report a case of middle ear and nasopharyngeal malignant melanoma where the primary is likely to have arisen in the middle ear and discuss the relevant literature. 相似文献

Primary adenocarcinoma of the temporal bone is a rare disorder. Fewer than 40 cases have been reported in the English literature, most of these being single case reports. Exclusion of metastatic adenocarcinoma is imperative. Adenocarcinomas must be differentiated from benign adenomas. Adenocarcinomas are best managed by aggressive surgical resection, with postoperative irradiation used in cases of incomplete resection or high-grade tumors. 相似文献

Petrosal cholesteatomas are rare lesions, which may be primary or acquired in nature. We report a case of primary cholesteatoma in petrous bone occurring in 51-year old woman who presented with a unilateral facial nerve palsy and conductive hearing loss, despite normal tympanic membrane appearance. Early diagnosis was facilitated by computed tomography scanning and magnetic resonance imaging. Complete cholesteatoma removal was accomplished using a transtemporal supralabyrinthine approach, which allowed hearing preservation. Facial nerve function is the main complication of these lesion. We suggest that use of CT scanning and MRI in unilateral conductive hearing loss may allow the earlier detection of the most cases of petrosal cholesteatomas. 相似文献

A Non-Hodgkin Lymphoma (NHL) represents nearly three percent of all malignant tumors. Thirty to fourty percent of the lymphomas are located extra-nodal. Within the head and neck region they might occur in the tonsils, tongue base or the sinuses, the larynx and the pharynx. A cutaneous manifestation is rare. We report on an extranodal B-cell-lymphoma of the ear in a young woman. She reported on a piercing of the pinna months before with a subsequent infection. This infection led to the development of a massive ear tumor. Histologic examination resulted in the final diagnosis. In spite of the considerable extent of the lymphoma there was no systemic manifestation and a total remission was induced by chemotherapy before adjuvant radiation. 相似文献

Primary adenocarcinoma is a rare tumor of the middle ear and temporal bone; its most frequent symptoms are hearing loss,
otalgia, and facial paralysis. Otoscopic examination of a 27-year-old man revealed purulent discharge in the ear canal, diffuse
edema, and hypertrophy of the right tympanic membrane. He presented with a grade III (House-Brachman) facial paralysis and
right conductive hearing loss with a history of aural discharge for 6 months, otalgia, and facial weakness for 2 days. Computed
tomography of the temporal bone showed an opacity filling the tympanic cavity, antrum, and aditus. Tympanotomy revealed diffuse
edema of the middle ear mucosa, and granulation tissue was encountered during mastoidectomy filling the antrum and periantral
cells and eroding the fallopian canal at the level of the oval window. After the histopathological examination revealed papillary
adenocarcinoma, a subtotal temporal bone resection, facial nerve segmenter resection, and end-to-end anastomosis of the facial
with the hypoglossal nerves were performed. The importance of histopathological examination in all cases of chronic otitis
media with granulation tissue is stressed.
