“…Hence, it was assumed to be benign or a low-grade malignancy and surgery was performed accordingly. It is important to mention that a case of mucinous cystadenoma in the parotid gland has been reported, where an ultrasonography guided needle biopsy was performed, without yielding a diagnosis [9]. This reveals that, in mucinous cystadenoma or a cyst surrounded by epithelium with thick fibrous tissue, a needle biopsy does not yield much information; thus, a needle biopsy may not help distinguish it from other salivary gland tumors.…”

“…In these reports, clinical features revealed a slow growing and asymptomatic mass similar to cystadenoma. In the case of a single mass in the major salivary glands, the diameter was 2.6 cm, while that of the mass in the minor salivary glands was 2.5 cm [8][9][10].…”

Mucinous cystadenoma, one of the subtypes of cystadenomas, is a rare benign salivary gland tumor. Most of the cases reported tumors presenting as asymptomatic, slow growing, single masses, primarily occurring in the parotid glands, buccal mucosa, and hard palate. This report describes a case of multiple mucinous cystadenomas that presented as subcutaneous swellings in both cheeks, which were mistaken for a benign subcutaneous tumor. A complete surgical excision was performed through an intraoral incision. There were no recurrences or complications. A diagnosis of mucinous cystadenoma was made by histopathological examination. Mucinous cystadenomas are differentiated from other salivary gland tumors based on the pathological findings. A malignant transformation is also possible. Preoperative imaging cannot identify mucinous cystadenomas because of their small size and atypical features, and needle biopsy has its limitations in such salivary gland tumors. Therefore, accurate diagnosis and treatment through surgical excision become important.
