Bilateral middle ear squamous cell carcinoma and clinical review of an additional 5 cases of middle ear carcinomas

A case report of otoendoscopic radiofrequency resection of squamous cell carcinoma of the external auditory canal

Squamous cell carcinoma is the most common pathological type of external and middle ear malignancy. Squamous cell carcinoma of the external auditory canal and middle ear is closely associated with long-term chronic inflammatory irritation. The patient was admitted with a major complaint of a "stuffy feeling in the left ear for more than three months." The results of the otoendoscopic examination were as follows: The left external auditory canal was filled with a granuloma-shaped mass with an unsmooth surface that showed obvious oozing of blood. The tympanic membrane was not visible. After the completion of the relevant examinations, radiofrequency resection of the external auditory canal mass was performed under otoendoscopy and the wound healed well with postoperative dressing changes. Pathological results revealed a well-differentiated keratinizing cutaneous squamous cell carcinoma and there was no recurrence throughout the next 5 years after the operation. Proper preoperative evaluation and the correct selection of surgical approaches can be of great importance. The primary complication of ear squamous cell carcinoma was local recurrence with a low incidence of metastasis. Early and complete resection was determined to be the optimal course of treatment.

Left Chronic Otitis Media with Squamous Cell Carcinoma of the Middle Ear and Postauricular Mastoid Fistula: A Case Report

Though squamous cell carcinoma is the commonest tumor, it rarely presents in the middle ear and follows a history of chronic ear discharge. Postauricular mastoid fistula is also a rare complication of chronic otitis media. These two pathological changes occurring simultaneously are even rarer. We report a rare case of a 37 years old male with a history of left-sided chronic ear discharge and conductive hearing loss. Squamous cell carcinoma along with postauricular mastoid fistula was diagnosed based on high-resolution computed tomography scan and histopathology. Left modified radical mastoidectomy with tympanic membrane grafting was done under general anesthesia. Often middle ear tumor is associated with long-standing ear discharge and this case is a very good example. The co-occurrence of the middle ear tumor with mastoid fistula is extremely rare as both the entities are rare in itself.

Poorly Differentiated Primary Carcinoma of the Middle Ear on 18F-FDG PET/CT

Primary carcinoma of the middle ear is extremely rare. A 41-year-old woman with a history of skull base osteomyelitis and chronic suppurative right otitis media presented with 1 month of right-sided facial droop, tearing, and headaches. Initial head CT revealed bony destruction and soft tissue opacification involving the right middle ear. Surgical biopsy yielded poorly differentiated carcinoma. Subsequent F-FDG PET/CT and MRI scans demonstrated FDG-avid soft tissue in the right middle ear with associated heterogeneously enhancing soft tissue on MRI.

A case of sensorineural hearing loss involving a fibroepithelial polyp of the middle ear

Primary middle ear neoplasms are rare, and commonly cause conductive hearing loss. When aural masses result in sensorineural hearing loss, malignant etiologies are often suspected. Fibroepithelial polyps are benign lesions commonly found in the skin and genitourinary tract and are not commonly identified as primary lesions of the middle ear. Here, we present a case of a benign fibroepithelial polyp of the middle ear causing sensorineural hearing loss and describe its surgical management. Imaging and histologic characteristics are reviewed.

Inverted papilloma involving the temporal bone and its association with squamous cell carcinoma: critical analysis of the literature

Inverted papilloma is a rare, benign neoplasm, which usually originates from the lateral nasal wall and can be locally aggressive, extending into surrounding structures. Unusually, this disease involves temporal bone. There have been only 18 reported cases in the literature. The available data regarding inverted papilloma of the temporal bone are reviewed, and its etiopathogenesis, recurrence rate and association with squamous cell carcinoma are discussed.

Cholesteatoma triggering squamous cell carcinoma: case report and literature review of a rare tumor

BACKGROUND

The aim of this study was to report a case of squamous cell carcinoma of the petrous part of the temporal bone associated with a long history of secondary acquired cholesteatoma in a 71-year-old man.

PATIENTS AND METHODS

We present the case of a 71-year-old man diagnosed with secondary acquired cholesteatoma in 1950. Treatments consisted of repetitive surgery owing to several relapses. In 2004, he presented with progressive fetid otorrhea. Clinical and computed tomography findings were indicative for relapsing cholesteatoma and a subtotal petrosectomy was performed.

RESULTS

Histologic work-up demonstrated a moderately differentiated squamous cell carcinoma. The staging revealed stadium pT3 cN0 cM0. Postoperative treatment consisted of local radiation therapy with intensity-modulated beam geometry with a total of 64.2 Gy in 30 fractions using a simultaneous integrated boost.

CONCLUSION

Middle ear carcinoma can arise from acquired cholesteatoma. The pathogenesis of squamous cell carcinoma associated with cholesteatoma has not been elucidated satisfactorily. Due to the complex anatomic features, intensity-modulated radiation therapy is the technique of choice for postoperative radiotherapy.
