Uncommon Tumor

Myoepithelial carcinoma is an uncommon tumor of the salivary glands, most commonly the parotid gland. Clear cell myoepithelial carcinoma is a rare variant with an aggressive behavior. Here, we describe a case of clear cell myoepithelial carcinoma arising from the hard palate in an elderly male who underwent resection of the tumor and postop radiation. Posttreatment imaging demonstrated bilateral pulmonary nodules and a C2 body lesion concerning for metastasis. Biopsy of the lung lesions revealed a monomorphous population of optically clear cells with hyperchromatic and pleomorphic nuclei which were morphologically similar to the prior resection specimen. There are few reported cases of clear cell myoepithelial carcinoma arising from the hard palate, and there are even fewer reports on metastases to the lungs. Due to the low number of reported cases, prognosis and treatment of this neoplasm is not well defined.

Sialadenoma Papilliferum

AbstractSialadenoma papilliferum is a rare, benign exophytic tumour of salivary glands. The preferred site of this tumour is usually the hard palate. A case of sialadenoma papilliferum occurring in the parotid gland of a 49-year-old man is presented; only one such case has been previously described.

Unusual Presentation

<p class="abstract">Mucoepidermoid carcinoma (MEC) is the most common malignant tumor of the salivary glands. This tumor usually occurs in the parotid gland and hard palate but rarely in the buccal region. We report the case of a 51 year old lady with mucoepidermoid carcinoma of left buccal mucosa. She was treated successfully with multimodal treatment including surgery, chemotherapy and radiotherapy. MECs have a female predilection and occur most commonly on the hard or soft palate or both and rare in the buccal mucosa.</p>

Pleomorphic adenomas are non-malignant tumours originating in epithelium. They are most often found in the parotid gland. Their location apart from the parotid gland is quite rare. That type of tumour is usually treated surgically. The aim of this paper is to describe own observations of the symptoms of pleomorphic adenomas that were not located in the parotid gland. Analysis of the clinical material was based on retrospective assessment of 41 patients hospitalised in the Department of Maxillofacial Surgery during the period 1991-2010 because of pleomorphic adenomas located in the small salivary glands. The group consisted of 24 women and 17 men aged between 24 and 79. Tumours were most often round or oval, between 0.7 cm and 3.5 cm and found in the palate area. All patients were treated surgically. Pleomorphic adenomas of small salivary glands, similarly to tumours located in the parotid gland, were more often found in women. Non-symptomatic course of the illness was the main reason behind late diagnosis. Tumours from the group of pleomorphic adenomas originated from small mouth glands were most often found in the hard palate.

Frequent Site

Myoepithelial carcinoma is a rare tumor of salivary glands, the most frequent site being the parotid gland. Myoepithelial carcinoma of the maxillary sinus has only been reported very few times. As the lesion is very rare in the maxillary sinus and due to the lack of specific guidelines for its treatment, its prognosis remains to be poor. We report a rare case of myoepithelial carcinoma in the maxillary sinus and discuss its diagnostic and therapeutic aspects.

Epithelial Myoepithelial Carcinoma

Abstract Epithelial-myoepithelial carcinoma (EMC) is a rare malignant salivary gland tumor, which is especially uncommon in the minor salivary glands (MSG). We report literature review of EMC of the MSGs with our experience of two cases. Case 1 is a 75-year-old woman with a hard elastic mass in the hard palate, sized 2.5 × 2 cm without ulceration. Incisional biopsy was suggestive of pleomorphic adenoma. Tumor resection was performed with adequate surgical margin. Case 2 is a 44-year-old woman with a mass in the hard palate, sized 1.8 × 1.6 cm without ulceration. Incisional biopsy was suggestive of pleomorphic adenoma or a low-grade salivary gland carcinoma and intraoral tumor resection was performed. Both have good postoperative courses and are alive with no evidence of local recurrence or metastasis at 25 and 10 months. The Ki-67 labeling index in Case 1 and 2 were 10.6 and 3.8 %. Considering that the anatomy, structure, and size of salivary glands are quite different from MSGs, EMCs of the MSG cannot be predicted similarly to EMCs of the major salivary glands. The present review with 18 cases revealed no consensus on treatment methods for MSG cases other than surgery.
