Acinic cell carcinoma (ACC) is a low-grade malignant salivary neoplasm that represents 17% of all salivary gland malignancies. It has a tendency to affect young individuals, especially females. ACC mainly originates in the parotid gland and has a potential for recurrence and metastases. Rarely, ACC can affect both parotid glands in a single individual. A bilateral ACC of the parotid gland could either present as a synchronous or a metachronous tumor. Our patient is a 19-year-old female known case of ACC of the right parotid gland. The tumor was resected in December 2017. After 3 years, she presented with a left parotid pain and swelling, which raised the suspicion of a contralateral metachronous tumor of the left parotid gland. In September 30, 2020 we proceeded with ultrasound-guided fine needle aspiration of the left intraparotid lesion, and the results turned out to be consistent with ACC. Here, we report a case of a 19-year-old female presenting with metachronous bilateral ACC of the parotid gland with an interval of 3 years, which is the 6 of its kind in the literature and the youngest amongst them.
Despite the rareness of metachronous occurrence of bilateral ACC of the parotid gland, it is still encountered in the medical practice. Here, we are highlighting the importance of follow-up with a periodic clinical and radiological examinations, bearing in mind the contralateral nonaffected parotid gland.
腺泡细胞癌(ACC)是一种低度恶性的涎腺肿瘤,占所有涎腺恶性肿瘤的17%。它倾向于累及年轻人,尤其是女性。ACC主要起源于腮腺,有复发和转移的可能。罕见情况下,ACC可在同一个体双侧腮腺发病。双侧腮腺ACC可表现为同时性或异时性肿瘤。我们的患者是一名19岁女性,已知患有右侧腮腺ACC。该肿瘤于2017年12月切除。3年后,她出现左侧腮腺疼痛和肿胀,这引发了对左侧腮腺异时性对侧肿瘤的怀疑。2020年9月30日,我们对左侧腮腺内病变进行了超声引导下细针穿刺,结果与ACC一致。在此,我们报告一例19岁女性,间隔3年出现双侧腮腺异时性ACC,这是文献中第6例此类病例,且是其中最年轻的。
尽管双侧腮腺ACC异时发生罕见,但在医疗实践中仍会遇到。在此,我们强调定期进行临床和影像学检查随访的重要性,同时要关注对侧未受影响的腮腺。
