Abstract
Sialolipoma is a rare benign neoplasm and was recently described as a histological variant of intraoral lipoma. In the current report, the case of a of a 65-year-old female with a slow-growing mass in the right parotid gland with recurrence is presented. The initial clinical diagnosis was a benign salivary gland tumor. The tumor was situated between the right parotid gland and the right masseter muscle; therefore, a superficial parotidectomy was performed. Histopathology revealed that the tumor was a sialolipoma of the parotid gland. During the three-month follow-up, a recurrent right parotid tumor was identified in the deep lobe space of the right parotid gland and a deep lobe parotidectomy was performed. The present case demonstrates that although surgical excision is generally sufficient to treat parotid gland sialolipoma, postoperative follow-up is required as multifocal lesions may potentially remain, which could result in recurrence.
Highlights
Sialolipoma is a rare histological variant of intraoral lipoma, characterized by the well‐circumscribed proliferation of mature adipose tissue and entrapped normal salivary glandular elements (1)
In the present case report, a lesion, which was later identified as a sialolipoma, was detected in the parotid gland of a 65‐year‐old female patient using Computed tomography (CT)
Sonography is the preferred imaging method for the majority of neck masses, CT and Magnetic resonance imaging (MRI) may be more effective for diagnosing a parotid gland neoplasm (1,2,6)
Summary
Sialolipoma is a rare histological variant of intraoral lipoma, characterized by the well‐circumscribed proliferation of mature adipose tissue and entrapped normal salivary glandular elements (1). The present report demonstrates an exceptional case of parotid gland sialolipoma with recurrence following the performance of a superficial parotidectomy, a revised deep parotid Computed tomography (CT) demonstrated a 2.3x1.7x1.9‐cm well‐circumscribed and mildly enhanced lesion, located between the right parotid gland and the right masseter muscle (Fig. 1A). A 3x3x3‐cm brown, soft, and well‐circumscribed mass was excised en bloc (Fig. 1B).
