Abstract
Objectives Ceruminous adenoma is a rare benign tumor of the external auditory canal. This study aimed to present the clinical characteristics, imaging findings, pathological results and the management outcomes of the ceruminous adenoma. Study design Retrospective case series review. Setting Tertiary referral center. Patients and methods Patients undergoing surgery for ceruminous adenoma of the external auditory canal between the years 2004 to 2018. All patients with ceruminous adenoma were analyzed for demographic, clinical, radiological features and pathologic findings. The outcomes of the management were also evaluated. Results Nine patients with ceruminous adenoma were included in the study. Hearing loss was the most common complaint (5/9, 56%), followed by otalgia (4/9, 44%), pruritus (4/9, 44%), and otorrhea (2/9, 22%). The tumors originated mostly from the cartilaginous portion of the external auditory canal (8/9, 89%) and merely from the bony portion of the external auditory canal (1/9, 11%). Pathohistological study indicated that the ceruminous adenomas were divided into three types: the ceruminous gland adenoma (6/9, 67%), the ceruminous pleomorphic adenoma (2/9, 22%) and the ceruminous syringocystadenoma papilliferum (1/9, 11%). No recurrence was found during follow-up for two to fifteen years after surgical resection. Conclusion Ceruminous adenomas are rare entities. They originate mainly from the cartilaginous portion of the EAC, but occasionally from the bony portion of the EAC. The surgical section with enough margin is adequate for management of these tumors.

Abstract
We describe a right external auditory canal (EAC) recurrent ceruminous pleomorphic adenoma (CPA) accompanied by itching and review the clinical features and histopathology of this disease. A female in her 70s presented with a right EAC mass accompanied by itching. We initially diagnosed the mass as a ceruminous gland adenoma (CGA) following excisional biopsy. Two years and nine months later, the tumor recurred at the same site. A preoperative computed tomography (CT) scan demonstrated no bone destruction, and magnetic resonance imaging (MRI) showed a 1 × 1 cm mass with a clearly defined margin in the right EAC. We completely excised the recurrent tumor using a transmeatal approach under general anesthesia. Histopathology demonstrated haphazard proliferation of tubule-glandular structures lined by two layers of the epithelium in the hypocellular stroma composed of a mucoid matrix. The recurring tumor was diagnosed as a CPA. Here, an EAC tumor-originally diagnosed as a CGA following excisional biopsy-recurred and was subsequently diagnosed as a CPA. CPA can be considered an unusual variant of CGA.

Abstract
Ceruminous pleomorphic adenoma is a very rare, mostly benign tumor originating from the ceruminal glands in the external auditory canal. Histologically, it is a mixed tumor with epithelial and stromal parts of different proportions, and is recognized today by the World Health Organization (WHO) as a ceruminous adenoma. Similar to the pleomorphic adenoma of salivary glands, recurrence or malignant degeneration with cellular atypia and metastasis can occur on rare occasions. Here, we describe an 87-year old female patient with a growing spherical mass in the right external auditory canal. After exclusive endoscopic tumor resection, a ceruminous pleomorphic adenoma was histologically diagnosed. Due to the absence of nuclear pleomorphism, no increased mitotic rate, no perineural invasion and no fusion transcripts of the MYB or MYBL1 gene loci, an adenoid cystic carcinoma could be excluded. The postoperative course was without any evidence of complications. A literature review identified 44 articles with 49 patients that were considered. Hearing loss and ear sensations were the most commonly reported symptoms. Most cases underwent an excision via an endaural or retroauricular approach. Recurrences were described in four patients, three of which had a malignant transformation.

Abstract
Salivary gland tumours constitute about less than 4 % of all head and neck tumours. Pleomorphic adenoma, also called benign mixed tumour, is the most common tumour of the salivary glands. About 80-90 % of these tumours occur in the major salivary glands mainly parotid gland and 10 % of them occur in the minor salivary glands. The most common site for pleomorphic adenoma of the minor salivary glands is the palate, followed by the lips and the cheeks. Other rare sites include the floor of the mouth, tongue, tonsil, pharynx, retromolar area and the nasal cavity. Here, we are reporting a case of pleomorphic adenoma of the minor salivary glands of the soft palate in a 36-year-old Indian female. The mass was removed by wide local excision with adequate margins under general anesthesia. There was no recurrence seen after a follow-up period of 1 year.

Abstract
Background. Pleomorphic adenoma (PA) is a benign tumour that mainly arises from salivary glands, and PA of the external auditory canal (EAC) is very rare. The objective of this study was to clarify the clinical presentation and treatment of PA of the EAC. Method. The authors present a case of PA arising from the EAC together with a literature review. Results. A 40-year-old man complained of hearing loss and foreign-body sensation of the right ear. Clinical and radiological examinations revealed a well-defined tumour limited to the EAC, with no connection to the parotid gland. Preoperative fine-needle aspiration cytology findings were characteristic of PA. The tumour was removed en bloc with the overlying skin. Conclusion. PA of the EAC is very rare, and methods to rule out malignancy before treatment are lacking. Thus, long-term follow-up is necessary, because malignant tumours are common in the EAC and PA has malignant potential.

Abstract
Pleomorphic adenoma (PA) is the most common benign mixed salivary gland neoplasm that accounts for 60% of all benign salivary gland tumors. It has diverse histological presentation and occurs in both major and minor salivary glands. PA of minor salivary gland in the palate is a common entity. We report the case of a 45-year-old female who presented with a painless slow growing swelling of palate over the last 20 years. The mass was extending to oropharynx causing mechanical obstruction of airway. Magnetic resonance imaging (MRI) depicted an oval-shaped mass occupying oropharynx and displacing the tongue inferiorly. Fine needle aspiration cytology (FNAC) was suggestive of PA. The entire tumor mass was excised along with overlying mucosa. Histopathological examination confirmed diagnosis of PA of minor salivary gland. There has been no recurrence of the lesion since 1 year.

Abstract
Pleomorphic adenomas, or benign mixed tumors, make up 65% of all salivary gland tumors. They also can be found as solid tumors in other parts of the head and neck region, such as the auditory canal, the eyelids, and the orbital area. In this study, we investigated extra-major salivary gland pleomorphic adenomas of the head and neck region retrospectively at a tertiary care center. Between March 1998 and June 2009, 37 patients underwent primary surgery for extra-major salivary gland pleomorphic adenoma of the head and neck. The duration of symptoms, radiographic findings, operative procedures, and pathologic findings were documented. Of the 37 patients enrolled, 22 were male and 15 were female, with a median age of 57 years. Tumors were found in the soft palate, hard palate, nasopharynx, orbital area, trachea, buccal mucosa, cheek, nasal septum, upper lip, lower eyelid, and external auditory canal. Cellular variant of the pleomorphic adenoma was found in four patients, while the remaining patients presented with the classic variant. No myxoid subgroup was noted in our study. Carcinoma ex pleomorphic adenoma was observed only in one patient for whom radical surgery was performed. Twenty-eight patients (76%) had long-term follow-ups, with the average follow-up period being 4.5 years. Local recurrence was observed in three patients, and they underwent revision surgery during the follow-up period. Our results indicate that extra-major salivary gland pleomorphic adenomas are most commonly found in the soft palate. Wide excision was the treatment of choice, although its efficacy might be compromised with cosmetics and functional structures of the head and neck. Therefore, long-term follow-up of patients is necessary.

Abstract
INTRODUCTION Primary neoplasms of the external ear canal are rare, and 5% of these tumors are of glandular origin. Ceruminal glands are modified sweat glands of the skin of the external auditory meatus that may give rise to (a) benign tumors such as ceruminous adenoma, pleomorphic adenoma, and syringocystadenoma papilliferum, and (b) malignant tumors such as ceruminous adenocarcinoma, adenoid cystic carcinoma, and mucoepidermoid carcinoma. An alternative theory holds that pleomorphic adenomas may well arise from ectopic salivary tissue present in the external ear canal. These tumors are very rare and usually have a benign course. In this report, we describe an unusual case of pleomorphic adenoma of the external auditory canal associated with chronic infection of the middle ear. CASE REPORT A 60-year-old woman presented with exacerbation of left otalgia over a 6-month period. She had been affected with chronic otitis media and aural polyps for the last 13 years, for which she had received medical treatment only. A canal-filling aural polyp was noted on clinical examination. Subsequent biopsy and histologic examination revealed pleomorphic adenoma of the external ear canal, possibly with malignant elements. Magnetic resonance imaging showed no intracranial extension or any association with the adjacent parotid gland. The patient underwent modified radical mastoidectomy and complete resection of the tumor and the entire skin of the external auditory canal. Final histology and immunohistochemistry confirmed the absence of malignancy, and no recurrence has been reported 1 year postoperatively. CONCLUSIONS Pleomorphic adenoma is an extremely rare tumor arising from the ceruminal glands of the external ear canal. Nonspecific presentation and difficult histologic diagnosis characterize this benign neoplasm. Wide local excision is the mainstay of treatment.
