“…FNA can confirm the lipomatous origin and benign behaviour of the mass (Tomo and others 2016), especially if advanced imaging is not available. The presence of fat and/or salivary gland epithelium from an FNA of this site should not be dismissed as non-diagnostic and should alert the clinician to the possibility of a sialolipoma.…”

“…As specified above, surgical excision and histopathology are necessary to get a definitive diagnosis of sialolipoma (Eldamati 2016). This partial (superficial) parotidectomy aims to preserve the facial nerve and has been performed in the majority of cases (Tomo and others 2016) with only one reported case of recurrence in the human literature. In this case, excisional margins were clear on histopathology and it was thought to be a novel and independent sialolipoma rather than recurrence from residual sialolipoma tissue (Lee and others 2014).…”

“…FNA has been reported in the human literature to be of little value in giving a final diagnosis of sialolipoma, due to the inability to confirm the presence of the characteristic fibrous capsule (Eldamati 2016), and the lesion containing mature adipose tissue and non‐neoplastic salivary gland tissue (Khazaeni and others 2013). FNA can confirm the lipomatous origin and benign behaviour of the mass (Tomo and others 2016), especially if advanced imaging is not available. The presence of fat and/or salivary gland epithelium from an FNA of this site should not be dismissed as non‐diagnostic and should alert the clinician to the possibility of a sialolipoma.…”

An eight-year-old male neutered boxer and a 10-year-old female neutered lurcher were presented with palpable masses in the region of the right parotid salivary gland. In both cases, fine needle aspirates yielded adipose cells, normal salivary epithelium and some blood contamination. CT images showed a mixed fat attenuating mass in the region of the right parotid salivary gland, without a normal ipsilateral parotid salivary gland. Surgical excision was performed in both cases and histopathology was consistent with sialolipoma. Neither mass has recurred 7 and 16 months after surgery. Sialolipoma should therefore be considered as a differential in dogs with a mass in this location. Fine needle aspirates showing salivary epithelium and adipose cells should not be dismissed as non-diagnostic. To the authors’ knowledge, these are the two first reported cases of sialolipomas of the parotid salivary gland in dogs and the first description of cross-sectional imaging of sialolipomas.
