Benign tumors of the middle ear cavity have wide spectrum of diseases. Facial nerve Schwannomas which arise along the facial nerve course are rare benign neoplasms that can be found in the middle ear cavity. Ipsilateral facial palsy and hearing impairment are the most common presentations. But because of the diversity of symptoms ranging from asymptomatic to atypical manifestations, the exact diagnosis of facial nerve Schwannoma may be difficult and the treatment can be delayed. Therefore, early diagnosis and treatment strategies are essential to preserve audiologic, vestibular and facial nerve function. We report a case of the facial nerve Schwannoma in intratemproal area masquerading as other benign tumors of middle ear cavity such as tympanic paraganglioma in a 58-year-old man presenting with left earfullness and hearing impairment without presenting facial palsy. We describe the diagnosis and the treatment strategies of facial nerve Schwannoma.

Pilomatrixoma is an unusual benign cutaneous tumor, originating from precursor cells that normally differentiate into hair matrix cells. The majority of pilomatrixoma is seen in the first two decades of life, and they are extremely rare in older patients. Thus, pilomatrixoma is often not considered in the clinical differential diagnosis of solitary, firm nodules in older adults. Most present as firm, solid nodules in the head and neck region. We present two cases of a non-calcifying pilomatrixoma in older patients. One lesion arose from the upper neck in 54 year-old male and the other from the cavum concha of left ear in 35 year-old male.

Facial nerve schwannomas(neurilemmoma) are uncommon tumors that involve the facial nerve. They are frequently misdiagnosed due to subtle and variable clinical presentations. We present a case of a 42-year-old female patient with facial nerve schwannoma who presented as sudden onset of facial palsy mimicking steroid responsive Bell’s palsy. This case shows that affected patients develop unilateral facial paralysis over one to three days with forehead involvement and no other neurologic abnormalities were developed. Patient with facial palsy who do not improve or aggravate on medication should include evaluation for other causes of facial nerve palsy of tumorous condition.

Schwannoma is a benign neoplasm emerging from the peripheral nerve sheath. Schwannomas in the nasal cavity sinuses are unusual compared to those in other head and ncek regions. In this case study, nasal schwannoma originating ofrm the right nasal cavity will be reported. A 13-year-old female presented with complaints of right nasal obstruction and dy spnea. A mass(4×4×5cm) that filled the right middle meatus was observed by an endoscopic examination. The mass was completely removed by endoscopic sinus surgery under general anesthesia.

Schwannoma is slow-growing, benign neurogenic tumor arising from schwann cells and rarely occurs in the middle ear cavity. The origins of primary schwannoma in the middle ear are the facial nerve, chorda tympanic nerve, and Jacobson’s nerve. Only a few cases have been reported of sympa-thetic plexus of the internal carotid nerve as the origin of primary schwannoma. We present a case of a 62-year-old male patient who have had recurrent otitis media for 20 years and accompanied by pus like discharge, otalgia, and hearing loss. On otologic examination, we found whitish mass in the middle ear cavity and performed temporal bone CT and MRI. There was soft tissue density filled the middle ear cavity with expansion of internal carotid canal petrous portion. We performed surgical exploration to rule out recurrence of chronic otitis media with cholesteatoma, the most common neoplasm in the middle ear cavity. The result of the biopsy was schwannoma. We report a case of schwannoma, which was suspected to be originated from sympathetic plexus of carotid artery.

Foreign bodies in external auditory canal (EAC) are one of the most common problem encountered in the emergency or outpatient department by otorhinolaryngologist. Patients present to the clinic with different type foreign bodies, ranging from small beads to living insects. They could lead to various complications, such as abrasion of EAC, otitis externa and tympanic membrane perforation. Therefore, it is important to identify and remove the foreign body while minimizing the damage of the surrounding structure. Here we present a case of foreign body found in EAC, initially misdiagnosed as hemorrhagic mass, which was later identified as Haemaphysalis longicornis Neumann, known as Asian long horned tick during the operation process. Reporting this case, we want to discuss about the importance of identifying the type of foreign bodies and about the tick-borne disease we have to consider when encounter the insects in EAC.

Carcinoid tumors are neuroendocrine tumors which arise from the enterochromaffin cells; the neoplasms grow slowly and are usually found in the gastrointestinal and bronchopulmonary systems. Carcinoid tumors in the middle ear are uncommon since the neuroendocrine cells have not been identified in middle ear mucosa. In this case, a 46-year-old man had tinnitus in right ear for a year. From otoendoscopy findings, we observed a complete perforation of right tympanic membrane and a pinkish mass like lesion at the center of the perforated tympanic membrane. Canal wall up mastoidectomy and tympanoplasty were done, and pathological findings showed cuboidal or columnar cells with small, round, and uniform nuclei; immunohistochemistry demonstrated positive for CD 56 but negative for S-100. Ki- 67 proliferation activity was low. While the patient underwent intubation for general anesthesia, a 2 cm polypoid mass was found at right base of tongue. The mass was removed by robotassisted surgery, and the pathology demonstrated neurilemmoma. The aut
