We report the case of a patient who came to us for evaluation of a progressive unilateral hearing loss and who was found to have a sebaceous nevus in an unusual location: the external auditory canal. A sebaceous nevus is a congenital organoid mass that occurs primarily on the face, scalp, and periauricular regions. Despite the predilection of sebaceous nevi for the head and neck, reports of this lesion rarely appear in the otolaryngology literature. Left untreated, the lesion can progress through three stages of gross and histopathologic development; a sebaceous nevus begins as a small benign papule, grows into an enlarging mass with different characteristics, and ultimately becomes a secondary neoplasm. The lesion's potential for malignant transformation and its association with syndromes underscores the importance of prompt recognition and appropriate management. This case report adds the sebaceous nevus to the differential diagnosis of external auditory canal lesions and provides essential information about this rare mass.

The Face

Nevus of Ota, a dermal melanocytic nevus, is rare in the Indian subcontinent. It presents as a brown, blue, or gray patch on the face and is within the distribution of the ophthalmic and maxillary branches of the trigeminal nerve. The oral cavity is infrequently involved in nevus of Ota. Only 11 cases have been documented in the English literature. We report a rare case of intraoral nevus of Ota in a 22-year-old male patient. This paper focuses on the differential diagnosis of oral manifestations of nevus of Ota to assist in proper followup to avert malignant transformation.

An acoustic neurinoma involving the internal auditory canal, the vestibule, the cochlea, the middle ear, and extending into the cerebellopontine angle and the external auditory canal, is described in a 56-year-old woman. An initial episode of vertigo was followed by a 27-year history of progressive unilateral hearing loss leading to complete deafness and areflexia with central compensation. The tumor was removed by a two-step surgical procedure, and the histologic features were those of a schwannoma.

AbstractObjective:We report a rare case of otological presentation of craniopharyngioma.Method:Case report and review of world literature concerning presentations of craniopharyngioma.Results:A six-year-old girl was referred to our department with unilateral hearing loss. This appeared to be a complete sensorineural hearing loss. Otoacoustic emissions were reproducible on both sides. Magnetic resonance scanning revealed a massive, cystic craniopharyngioma exerting pressure on the patient's ventricular system and brainstem and also invading the internal acoustic canal. The mass was resected via a craniotomy. The patient's hearing loss completely recovered, and she experienced no neurological or endocrinological side effects of the treatment. Craniopharyngioma have a prevalence of 0.13–2:100 000.Conclusion:Craniopharyngioma is a rare disease. First presentation with otological symptoms is extremely rare. Otoacoustic emissions can differentiate between cochlear and retrocochlear causes of sensorineural hearing loss.

<p class="abstract">Independently arising acrochordon of the external auditory canal is a rare entity with only one reported case in literature. We present here the second such case. A 54-yr old lady presented to our outpatient department with complains of aural fullness and reduced hearing in right ear for 2 weeks. Clinical examination showed a pedunculated polypoidal growth in the external auditory canal. Excisional biopsy and histopathology revealed an acrochordon. Following the procedure, patient was free of symptoms and all structures of the right ear were normal. In the head and neck region, acrochordons have only but once been reported in the external auditory canal and hence should be considered as a differential diagnosis in the masses of this region. Resection must be done for confirmation of diagnosis, differentiation from neoplasia and alleviation of symptoms when associated.  </p>

AbstractObjectives:To present a rare case of rectal adenocarcinoma metastasising to the external auditory canal, in a patient in whom computed tomography staging of the abdomen, chest and pelvis was clear for metastatic disease.Methods:Case report and review of the literature.Conclusions:Metastatic tumours to the external auditory canal are rare, with rectal adenocarcinoma being one of the rarest. However, it is important that the external auditory canal is regarded as a potential site for metastasis, even when computed tomography staging is clear. Metastatic tumour should be included in the differential diagnosis of a patient presenting with an ear mass.

This chapter presents a case example of a patient with progressive unilateral hearing loss who was ultimately diagnosed with a skull base schwannoma. The workup and differential diagnosis are presented and options for treatment are reviewed based on published evidence. Treatment options include observation, stereotactic radiosurgery, and surgical resection. The objective status of a patient’s hearing as well as the patient’s age influence treatment recommendations and the surgical approach. Intraoperative neuromonitoring provides real-time assessment of facial nerve irritation as well as cochlear nerve function and is an important component of surgery. Complication avoidance and management are also discussed in this chapter.

Herniation of the tympanic membrane is a rare benign malformation of the tympanic membrane into the external auditory canal. It may be asymptomatic or associated with symptoms such as aural fullness, tinnitus, otalgia or hearing loss. We present a case of a symptomatic herniation of the tympanic membrane and its surgical therapy with hernia excision and tympanoplasty. An internal review board exemption was obtained.
