To describe a case of mucoepidermoid carcinoma of the parotid gland that caused obstruction of a salivary gland duct and manifested as a parotid retention cyst.
A 21-year-old woman presented with a 5-cm cystic swelling in her left parotid region. Ultrasound examination and a computerized tomography scan showed a clearly outlined parotid cyst. Through a conventional parotidectomy incision, the cyst was excised with parotid gland tissue around the lesion. The patient had an uncomplicated recovery.
Histopathological examination of the resected parotidectomy material showed a parotid retention cyst and a mucoepidermoid carcinoma measuring 5mm in diameter.
Among acquired cysts of the parotid gland, retention cysts are the most frequent. They may be the presenting symptom in patients with occult cancer of the parotid. In this case report, a mucoepidermoid carcinoma played a significant role in the obstruction of a salivary gland duct and caused a parotid retention cyst. Thus, a wide excision of the parotid retention cyst is necessary, as is a careful review of the histology searching for malignant lesion.
描述1例腮腺黏液表皮样癌，其导致涎腺导管阻塞并表现为腮腺潴留性囊肿。
一名21岁女性，左腮腺区出现一个5厘米的囊性肿物。超声检查和计算机断层扫描显示一个边界清晰的腮腺囊肿。通过传统腮腺切除术切口，将囊肿连同病变周围的腮腺组织一并切除。患者恢复过程顺利。
对切除的腮腺手术标本进行组织病理学检查，显示为一个腮腺潴留性囊肿和一个直径5毫米的黏液表皮样癌。
在腮腺后天性囊肿中，潴留性囊肿最为常见。它们可能是腮腺隐匿性癌患者的首发症状。在本病例报告中，黏液表皮样癌在涎腺导管阻塞中起了重要作用，并导致腮腺潴留性囊肿。因此，广泛切除腮腺潴留性囊肿以及仔细检查组织学以寻找恶性病变是必要的。
