“…Mucinous cyst adenoma forms a cystlike lumen backed by multiple layers of mucinproducing cells, many of which are morphologically cubic or scyphi form, but squamous areas are also present, and the epithelium does not form papillary protrusions 8,31) .

Cystadenoma, a common benign tumor derived from glandular tissue, generally occurs in the appendix, ovaries, kidney, or pancreas. While rare in the oral and maxillo facial region, they do sometimes occur in the parotid or minor salivary glands. We report a case of cystadenoma arising in the upper lip region. The patient was a 37yearold woman referred to our hospital with a painless mass on the left upper lip initially found during treatment at a local dental clinic. The medical history was noncontributory. The 7×5mm mass was welldefined, elastic, and flexible. The surface of the mucosa appeared healthy. The mass was clinically diagnosed as a benign tumor of the left upper lip. Because the tumor was painless and slowgrowing, and magnetic resonance imaging suggested that it was benign, resection was performed under local anesthesia without biopsy. Histopathologically, cystadenoma was diagnosed. No signs of recurrence or metastasis have been seen as of 24 months postoperatively and the progress of the patient has been satisfactory.
