“…In the presence of a salivary gland tumor with cystic change, the differential diagnoses of Warthin tumor, basal cell adenoma, cystadenoma, mucoepidermoid carcinoma, acinic cell carcinoma, and cystadenocarcinoma were considered. Histopathologically, PA of the minor salivary glands is usually unencapsulated [32], and approximately 50% of tumors of the minor salivary glands are considered to be malignant [1] [33]. Histopathologically, differential diagnoses include simultaneous occurrence of PA and dermoid cysts.…”

The incidence of pleomorphic adenoma (PA) of the minor salivary glands is reported to be 10%, and while the histological findings in PA can be diverse, keratin-filled cysts lined by squamous epithelium are rarely reported. The condition can, however, present with cyst formation in some cases. We review a rare case of pleomorphic adenoma in the buccal mucosa that involved the formation of multiple squamous epithelium-lined cysts in a 69-year-old woman. Magnetic resonance imaging (MRI), fine needle aspiration cytology, and histopathological examination were performed. Physical examination revealed a painless, mobile, elastic hard mass in the right buccal mucosa, measuring 2.5 × 1.0 cm. The MRI revealed a well-defined lesion with different signal intensities in the medial and distal regions of the right cheek. The medial side of the lesion showed a low signal intensity on T1-weighted imaging (T1WI) and T2-weighted imaging (T2WI), while the distal side showed a low signal intensity on T1WI, and a high signal intensity on T2WI and short tau inversion recovery (STIR) imaging. Fine needle aspiration of the lesion was performed under local anesthesia and a cytological diagnosis of an epidermoid or dermoid cyst was made. The tumor was completely resected under local anesthesia combined with intravenous sedation. The histopathological examination demonstrated the proliferation of atypical tumor cells with poor atypia and the formation of glandular, alveolar, large, and small cysts. The cysts were lined by keratinized squamous epithelial cells, their cavities were filled with keratinous material, and foreign body reaction was observed

“…While Velpula and other authors performed ultrasonography, fine needle aspiration cytology (FNAC) and/or computed tomography (CT) prior to MRI, we performed MRI ( 1 , 2 , 4 , 14 ). Being the clinical presentation strongly suggestive for a benign tumor of soft tissues, MRI was considered to be appropriate as first line imaging investigation, thus limiting invasiveness and unnecessary exposure to radiation ( 10 ).…”

“…Such a feature may account for some of the recurrences observed in cases of presumptive radical excision ( 12 ). On the basis of the impossibility to precisely assess the presence of malignant cells or microscopic extracapsular spread, the preferred treatment for PA consists in wide local excision (0.5 cm free margins) and follow-up for at least 3-4 years ( 4 ). This procedure was, in fact, performed in the totality of the reviewed cases, where no recurrences were reported.…”

Large-sized pleomorphic adenoma of the cheek treated with Nd:Yag laser: report of a case and review of the literature

et al. 2020

View full text Add to dashboard Cite

Pleomorphic adenoma (PA) mostly involves parotid glands, while extra-parotid localizations are relatively uncommon. Particularly, PAs of the cheek minor salivary glands with a size larger than 4 cm are exceedingly rare, with only few cases reported. Surgical treatment of PA usually consists in radical excision. However, despite a presumptive radicality, recurrences, sometimes followed by malignant transformation, may occur. Here we report a case of a large-sized (6 cm) PA of the cheek minor salivary glands in a 70 year-old female patient, successfully treated through a conservative approach, based on the use of Nd:YAG Laser (λ=1064 nm). No recurrences were observed after a 2-year follow-up. A concise review of the literature, describing the features of 14 cases is also provided. Advantages of laser treatment include a precise cut, reduction of trauma on surrounding tissues, the possibility of a very good intraoperative hemostasis. Such features may sometimes allow to avoid general anesthesia, even for removal of big lesions. Post-operative course, in terms of pain and swelling, is usually better for intervention performed with laser, when compared to traditional surgery. Key words: Oral surgery, oral pathology, pleomorphic adenoma, laser surgery, minor salivary glands, salivary glands tumors.

“…Salivary gland neoplasm accounts for 3-5% of all head and neck tumors. 1 Minor salivary gland tumor accounts for <25% of the total salivary neoplasms. 2 PA is the most common tumor of the major and minor salivary gland, 85% occur in the parotid gland and 7% in the minor salivary glands.…”

Pleomorphic Adenoma (PA) is the most common tumor of the salivary gland, arising mostly from the parotid gland while small percentage from the minor salivary gland. The most common sites of pleomorphic adenoma of the minor salivary glands are the palate, followed by lips. The buccal mucosa or cheek is a rarely affected site by PA of the minor salivary glands. Here, we present a case report of PA of the buccal mucosa, presented with intraoral swelling, complete surgical excision was done with a follow up of 3.5-years.
