Abstract
Neoplastic lipomatous lesions of the salivary glands constitute ≤0.5% of all the salivary gland tumors. Oncocytic sialolipoma of the parotid glands is extremely uncommon. We report a case of oncocytic sialolipoma of the parotid gland in a 59-year-old male who presented with a gradually increasing swelling of the right parotid. Excisional parotid biopsy performed in view of possible pleomorphic adenoma as suggested on ultrasonography showed histological features consistent with oncocytic sialolipoma. We also described the characteristics of 24 previously reported cases of oncocytic sialolipoma of the parotid gland. The median age of the patients including the present case was 56 years (range 7-89), and 14 were male. The largest and the least reported sizes of the tumor were 7.0 and 1.4 cm, respectively. The left-sided parotid gland was more commonly involved (14/23). Despite its rarity, oncocytic sialolipoma should be considered in lipomatous parotid lesions showing epithelial components with oncocytic changes.
期刊介绍：
The journal will cover studies related to pathology including morbid anatomy, surgical pathology, clinical pathology, diagnostic cytopathology including gynecologic cytology and aspiration cytology, hematology including immuno-hematology and medical microbiology. The journal gives preference to clinically oriented studies over experimental and animal studies. The Journal would publish peer-reviewed original research papers, case reports, systematic reviews, meta-analysis, letters to the editor and brief communications. Review articles on current topics usually are invited by the editor.
