Ultrastructural Findings

AbstractA 56-year-old woman presented with unilateral tinnitus and hearing loss for 18 months. A middle ear mass was detected clinically. At operation, the tumour was found to have eroded the stapes. The light and electron microscopic features of the tumour were those of a middle ear adenoma. This rare benign tumour has an excellent prognosis. Erosion of an ossicle has not been previously associated with this tumour.Benign adenomatous tumours arising from middle ear mucosa are rare (Mills and Fechner, 1984). The term adenoma of middle ear was proposed by Hyams and Michales (1976), and their review of 20 cases emphasized the benign behaviour of these tumours. We report a case of middle ear adenoma in which ossicular erosion occurred.

Introduction. Despite modern radiological workup, surgeons can still be surprised by intraoperative findings or by the pathologist’s report.Materials & Methods. We describe the case of a 52-year-old male who was referred to our clinic with a single sided conductive hearing loss. He ultimately underwent middle ear exploration and excision of a middle ear tumour followed by second look and ossiculoplasty a year later.Results. Though preoperative CT and MRI scanning were suggestive of a congenital cholesteatoma, the pathologist’s report diagnosed a middle ear adenoma.Discussion. Middle ear glandular tumors are extremely rare and, despite numerous histological techniques, continue to defy satisfactory classification. Most surgeons advocate surgical excision though evidence of the tumour’s natural course and risk of recurrence is lacking.

Histopathological Results

Most reported cases of middle ear adenoma (MEA) have focused on histopathology because MEA is usually diagnosed postoperatively, which is considered as a major setback. We focused on the surgical aspect of the disease to facilitate a preoperative diagnosis, resulting in prompt and proper treatment, without requiring a second stage of surgical treatment. In this report, we present the differential diagnoses in a 40-year-old man with MEA requiring surgical treatment. Preoperatively, the patient was suspected to have an MEA. An analysis of the surgical procedures in similar misdiagnosed tumors has enabled us to assess surgical procedures in cases wherein the preoperative diagnosis does not coincide with the postoperative histopathological results.

The effect of platelet activating factor (PAF) was studied to elucidate its role in the pathogenesis of otitis media and sensorineural hearing loss. The PAF alone did not induce a reduction of ciliary activity of the cultured middle ear mucosa. However, a dose-dependent decrease in ciliary activity was observed in the presence of the medium containing both PAF and macrophages. Intravenous injection of PAF did not induce dysfunction of the mucociliary system or morphologic changes of epithelium in the tubotympanum, but cytoplasmic vacuolization and ballooning were observed in the inner ear within 1 hour after injection of PAF. In contrast, intratympanic injection of PAF induced mucociliary dysfunction and some pathologic changes in the tubotympanum. Intratympanic inoculation of PAF induced no pathologic findings in the inner ear. These results suggest that PAF is at least partially involved in the pathogenesis of certain middle ear diseases such as otitis media with effusion. Additionally, PAF might be involved in the pathogenesis of some types of unexplained sensorineural hearing loss.

AbstractObjective:We present a technique which we have found useful for the management of congenital cholesteatoma extensively involving the middle ear.Case report:A five-year-old boy was presented to our department for management of a white mass on the right tympanic membrane. This congenital cholesteatoma extensively occupied the tympanic cavity. It was removed through an extended tympanotomy approach using our modified sleeve technique. The conventional tympanotomy approach was extended by gently separating the tympanic annulus from its sulcus in a circular manner. The firm attachment of the tympanic membrane at the umbo was not severed, in order to avoid lateralisation of the tympanic membrane.Conclusion:Although various operative techniques can be used, our modified sleeve tympanotomy approach provides a similarly sufficient and direct visualisation of the entire middle ear, with, theoretically, no possibility of lateralisation of the tympanic membrane and subsequent conductive hearing loss.

Objectives: To describe the features of an oropharyngeal and hypopharyngeal myxoma.Materials and methods: Case report of a 34-year-old patient operated upon for a dual-location tumour, and review of the literature.Results: The myxoma is a rare tumour. Various head and neck locations have been described, but not (to our knowledge) a tumour in both the oropharynx and the hypopharynx. Multiple synchronous locations must be searched for, particularly regarding cardiac myxoma.Conclusion: The myxoma is a rare, benign tumour, even rarer in the head and neck. Surgical treatment must be complete in order to avoid recurrences, and should be performed after assessment for cardiac involvement.

Rare Benign Tumour

Angioleiomyoma is a rare benign tumour of uterus. We are presenting an unusual case of 45-year-old female with 11 kg giant angioleiomyoma of uterus which was masquerading as ovarian tumour on imaging. Exploratory laparotomy was done which was suggestive of huge lobulated mass arising from the uterus. Hysterectomy with bilateral salpingo-oophorectomy was done. Histopathological examination of specimen was suggestive of uterine subserosal and broad ligament angioleiomyoma of cavernous type. This case is being reported because of its rarity and challenges in diagnosis and management.
