Pleomorphic adenoma directly arising in the neck is thought to originate from heterotopic salivary gland tissue. In this article, we present the case of a 55-year-old female patient with a histologically proven pleomorphic adenoma located at the left mandibular angle, anteriorly to the sternocleidomastoid muscle and posteroinferiorly to the submandibular gland. As the patient also had an ipsilateral thyroid nodule with coarse calcifications, clinical and radiological features suggested a possible level II metastatic lymph node. However, ultrasound-guided fine needle aspiration cytology and postsurgery histopathological examination revealed a pleomorphic adenoma arising from heterotopic salivary gland tissue unrelated to a benign thyroid nodule. In this article, we provide a review of the existing literature on heterotopic salivary gland tissue and related neoplasms and discuss their imaging presentation.

<p>Pleomorphic Adenoma is a benign epithelial tumor arising from the salivary gland. It is a benign mixed tumor composed of epithelial and myoepithelial cells arranged with various morphological patterns, demarcated from surrounding tissues by fibrous capsule. In this article, we report an unusual case of 30 year, male with a single, nodular swelling evident in the upper lip which was discovered during a routine dental procedure. Fine Needle Aspiration Cytology (FNAC) was planned for the patient, where a of cytological diagnosis of Pleomorphic Adenoma was rendered, which was confirmed by biopsy. Hence, this highlights, FNAC makes up an important diagnosing tool as the first line of investigation to distinguish between benign and malignant salivary gland neoplasms.</p>

<p class="abstract">Malignant oncocytoma is an extremely rare neoplasm of the salivary gland accounting for 0.5% of epithelial salivary gland malignancies and 0.18% of epithelial salivary gland tumors. We report a case of malignant oncocytoma of left parotid gland in a 61-year old female patient. Patient presented with a 6-year history of painless swelling in the left parotid region. Fine needle aspiration cytology of the swelling was suggestive of pleomorphic adenoma. A computed tomography scan performed did not reveal any features suggestive of malignancy. Patient underwent left superficial parotidectomy. However, histopathological examination of the specimen turned out to be malignant oncocytoma. Malignant oncocytoma of salivary glands have rare incidence and may have similar morphologic features with other neoplasms. Despite the tumor being large and malignant in this case, there was no facial palsy preoperatively. As histopathology is often diagnostic, the possibility of malignancy always must be kept in mind preoperatively even when there is no facial palsy or fine needle aspiration cytology not showing up malignancy.</p>

Pleomorphic adenoma, otherwise called as benign mixed tumour, is the most common salivary gland tumour which accounts for 60% of all benign salivary gland tumours. The clinical, radiological and histopathological presentations are varied. The tumour occurs in diverse anatomical sites and can consist of epithelial and mesenchymal components. In this case report, the patient reported with an asymptomatic swelling on the face. CT scan with contrast was advised. The clinical, roentgenographic findings and Fine Needle Aspiration Cytology were indicative of pleomorphic adenoma of the parotid gland. Treatment included partial superficial parotidectomy under general anaesthesia using the modified Blair’s incision. The facial nerve was not involved. Part of the gland along with the tumour was resected completely superficial to the facial nerve with a margin of normal tissue all around. Histopathologic examination of tissue specimen confirmed the lesion as pleomorphic adenoma. The patient was asymptomatic at 6-month follow-up.

Objectives: Salivary gland tumors account for only 3% of head and neck tumors. Their character is mostly benign, although tumors of the submandibular gland are more often malignant. The purpose of this article was to evaluate the structure of patients operated due to submandibular gland tumor and to study the correlation between fine-needle aspiration cytology and postoperative histopathological examination. Methodology: We retrospectively analyzed the medical records of all patients with submandibular gland tumors. The collected data included the demographic structure, results of preoperative fine-needle aspiration cytology and postoperative histopathologic examination. Results: We analyzed 58 patients – 35 women and 23 men with a mean age of 56.6 years. The character of the lesion was benign in 45 cases and malignant in 13. The most frequent benign tumors were pleomorphic adenoma, inflammatory tumor and Warthin’s tumor, whereas most common malignancies were carcinoma planoepitheliale and lymphoma . There were four recurrences. Moreover, we compared results of preoperative fine-needle aspiration cytology and histopathological findings. The accuracy of this examination was almost 83%; 56% of incorrect results involved nondetection of malignancies. The sensitivity and specificity in the diagnosis of those tumors were 58.3% and 97.5%, respectively. Conclusions: The most common types of submandibular gland are pleomorphic adenoma and carcinoma planoepitheliale and lymphoma amongst malignancies. Fine-needle aspiration cytology is accurate in the preoperative diagnosis, mistakes are mostly caused by underdiagnosis of malignant tumors.
