ABSTRACT
Background: Primary malignant neoplasms of the external auditory canal are very
rare; in which, cystic adenoid carcinoma is an extremely rare tumor that represents
approximately 5%. Most patients present with constant unilateral otalgia, intense, of
prolonged duration, decreased hearing and increased volume in the external ear. These
tumors are treated with aggressive surgical excision or radiation therapy, depending on
the extent of the lesion. Despite this, the general prognosis is reserved due to recurrence
and distance metastases.
Clinical case: The cases of two patients, a woman and a man aged 52 and 41,
respectively, who were diagnosed with adenoid cystic carcinoma, are reported.
Conclusions: Adenoid cystic carcinoma should be included in the differential
diagnosis in patients with ear pain and a tumor lesion in the external auditory canal
for more than 6 months.
