Sialolipoma of salivary glands: Two case reports and review of the literature
A 45-year-old female presented with a painless mass in the right parotid gland. The patient had neither any systemic diseases nor any trauma on the region. The overlying skin was normal in color and appearance. A course of antibiotic therapy had been prescribed to rule out infection causes without any beneficial effect. An ultrasound imaging showed a relatively solid hypoecho nodule in the right parotid gland at the superficial lobe []. Fine needle aspiration (FNA) was performed. Under general anesthesia, superficial parotidectomy was done, superficial lobe with tumor was freely separated from adjacent tissue. The gross specimen contained a soft, brown-yellowish lobulated mass with definitive borders measuring 7.5 × 5 × 2.5 []. Microscopically, the specimen showed mature adipose tissue with some salivary gland structure. The ratio of mature adipose tissue to salivary gland tissue was 2:5 []. A one-year follow-up period showed no evidence of recurrence [].
