Introduction: Acinic cell carcinoma (Acc) is a low-grade malignant salivary neoplasm that constitutes approximately 17% of primary salivary gland malignancies in the head and neck region. The parotid gland is the predominant site of origin and women are usually more frequently diagnosed. The diagnosis is usually confirmed with a fine needle aspiration biopsy, and surgical excision is the main treatment of this malignant neoplasm. Acc has a significant tendency to recur, to produce metastase, and may have an aggressive evolution. Therefore, long-term follow-up is mandatory after treatment. Objectives: To describe a case of a parotid tumor - acinic cell carcinoma - involving the superficial and deep lobe, with invasion of the external ear canal. Case report: Female, 35 years old, without comorbidities, came to the head and neck surgery outpatient clinic complaining of otalgia in the right ear in addition to bulging in the topography of the parotid gland since the beginning of the year 2021. On physical examination, bulging preauricular region on the right side. Otoscopy showed no changes. Imaging tests such as computed tomography and magnetic resonance imaging were requested. She underwent surgical resection with preservation of the facial nerve, and adjuvant chemotherapy. Conclusion: Acinic cell carcinoma is a rare malignant epithelial neoplasm of the salivary glands that predominantly affects the parotid gland in the female population. Less common occurrences of this neoplasm are reported in the palate, maxillary sinus, lips and buccal mucosa. [ABSTRACT FROM AUTHOR] |
