“…It helped to have better access to the whole tumour. The histopathologic characteristic most frequently associated with recurrent tumour is a myxoid stroma (similar to what was found in the specimen of this patient), which could be spilled into the surgical field, providing a nidus for future recurrence [13,16].…”

Background/aim: Pleomorphic adenoma is a common slow growing benign tumour that is known to occur mainly in the salivary glands. Case reports of pleomorphic adenomas originating from the external auditory canal have been extremely rare. Case presentation: We report the case of a 64-year-old patient who presented with 2-year history of a slow growing mass of the left external auditory canal. Excision of the mass was performed and pathology was consistent with pleomorphic adenoma. Conclusion: Pleomorphic adenomas of the external auditory canal are uncommon and can be easily misdiagnosed as aural polyps or granulation tissue. Biopsies are often necessary for an accurate diagnosis.

“…There was no sex predilection. Common symptoms related to primary PA of the EAC included obstruction of the EAC meatus, hearing loss, otalgia, and otorrhoea [3][4][5][6][7][8][9][10][11][12][13].…”

“…However, PA may also arise from the external auditory canal (EAC), although reports are very rare. Since 1951, when Mark and Rothberg published their first EAC pleomorphic adenoma report [2], at least 35 similar cases have been reported [3][4][5][6][7][8][9][10][11][12][13]. PA of the EAC is classified as a type of ceruminal gland tumour.…”

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 welldefined 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.

“…The outer one-third of the auditory canal contains ceruminous and sebaceous glands, which are absent in the inner two-thirds of the ear canal and the middle ear. Primary tumors of the external auditory meatus are very rare; they grow slowly and affect both sexes equally with median age of 50 years [ 12 ]. Five percent of these tumors are ceruminous (modified sweat) gland tumors [ 3 ].…”

A 55-year-old male presented with a nine-month history of gradually enlarging, painless mass in the right external auditory canal associated with hearing loss and occasional bleeding. Examination demonstrated complete obstruction of the outer 1/3 of the external auditory canal by a firm, pink, rubbery mass. CT scan of the temporal bone showed tumor mass with no evidence of bone destruction. The tumor was excised and histopathology confirmed a diagnosis of ceruminous pleomorphic adenoma of the external auditory canal. Six months following the surgery, patient is free of any recurrent disease.
