Pleomorphic adenomas are the most widespread epithelial tumours originating from the salivary glands. In almost 90% of the cases, they are localized in the parotid salivary glands. Pleomorphic adenomas only rarely affect the larynx. To the best of our knowledge, as many as 27 cases of laryngeal pleomorphic adenoma have thus far been described in the special literature. The present article was designed to report a case of pleomorphic adenoma in the larynx of a 76 year-old male patient. The surgical treatment of this condition proved beneficial for the patient whose condition remains uncomplicated by the relapse of the tumour during the 5 year-long postoperative follow-up...

The aim of this study was to investigate the benefits and potential pitfalls of transcervical extracapsular dissection in the treatment of parotid gland tumours in the parapharyngeal space. We retrospectively evaluated the records of all patients with parapharyngeal parotid gland lesions treated between 2000 and 2015 by transcervical extracapsular dissection. Patients having revision operations and patients whose records were not complete were excluded, leaving 49 patients in the study. We found acceptable oncological and functional outcomes throughout...

Pleomorphic adenoma is a slow-growing salivary gland tumor frequently arising from the parotid gland. In this study, we investigated the role of the insulin-like growth factor I-II receptor (IGFI-IIR) levels on the development of parotid gland pleomorphic adenomas. The study included 20 males and 20 females who had superficial parotidectomy with a histopathological diagnosis of pleomorphic adenoma in Fırat University Otorhinolaryngology Clinic between 2000 and 2011. The ages of the patients ranged between 20 and 50 years...

The aim of the study is to define the utility of ultrasound (US) in differentiating benign from malignant parotid tumors as well as pleomorphic adenomas (PA) from monomorphic adenoma (MA). Seventy-two consecutive parotid gland tumors were analysed with high-resolution ultrasonography (12 MHz) with color Doppler imagining. The histopathological diagnosis was confirmed after parotidectomy for each lesion. The sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) for the US were established...

Salivary gland tumors and tumor-like lesions in the pediatric population are uncommon. They comprise a heterogeneous group of infectious/inflammatory and neoplastic conditions. Pediatric salivary neoplasms include benign tumors of mesenchymal or epithelial origin as well as malignancies of epithelial (carcinomas), mesenchymal (sarcoma) or hematolymphoid (lymphoma) derivation. Infectious/inflammatory conditions and hematolymphoid malignancies may represent either genuine parenchymal pathology or conditions involving intraglandular lymph nodes of the parotid glands (intraglandular lymphadenopathy and intraglandular nodal lymphomas)...

A 44-year-old man presented with swelling in the left parotid region. The swelling was firm and Fine Needle Aspiration Cytology report proved pleomorphic adenoma. In the CT scan, the tumour was confined to the superficial lobe of parotid. So, left superficial parotidectomy was planned. Modified Wilson Blair's incision was used. On course of identifying the facial nerve, a large calibre vein was identified running vertically through the parotid substance. Assuming it as retromandibular vein, further dissection was carried out more meticulously...

Basal cell adenoma is a rare benign salivary gland neoplasm exhibiting an isomorphic basaloid tumour cell pattern, commonly occurring in the parotid. Membranous variant warrants separate consideration because of its recurrence and rate of malignant transformation. We report a case of membranous type basal cell adenoma occurring in minor salivary gland in a 61-year-old female patient. The histopathological diagnosis was supported by immunohistochemical analysis and serum Carcinoembryonic antigen level.

Carcinosarcoma of the parotid gland, a true malignant mixed tumour is extremely rare. It may occur in a pre-existing pleomorphic adenoma or arise de novo. We report a case of carcinosarcoma de novo harbouring an osteosarcomatous element in a 35-year-old man along with review of the reported cases. Excision was done and histopathologic examination confirmed the diagnosis. Long term follow up has been recommended for these tumours owing to their high propensity of recurrence and metastasis. Our case discusses the importance of histopathology and limitation of preoperative imaging in the diagnosis of such an aggressive neoplasm; emphasizing the fact that possibility of carcinosarcoma should be kept in mind while dealing with salivary gland lesions even at a younger age...

Lymphoepithelial carcinoma is a variant of undifferentiated carcinoma with characteristic dense lymphoid stroma in which nasopharynx is site of predilection. Racial and geographic association and Epstein-Barr virus positivity in endemic areas are other characteristics of this rare neoplasm. Lymphoepithelial carcinoma accounts for only 0.4% of malignant salivary gland tumors. The authors present a patient with Epstein-Barr virus positive lymphoepithelial carcinoma of the parotid gland in a nonendemic region...

Malignant non-basaloid tumors that arise from basal cell adenoma (BCA) are extremely rare. The patient was a 72-year-old Japanese male, who had noticed swelling of the left parotid region 21 years ago. A superficial lobectomy was performed. About 60% of the tumor was made up of cribriform and trabecular tissue composed of basaloid cells, which exhibited mild atypia and nuclear expression of β-catenin. This portion of the tumor was considered to be a BCA. In the other part of the tumor, the proliferation of large eosinophilic atypical cells, most of which formed intraductal structures, was observed...

Basal cell adenoma is a rare benign salivary gland neoplasm. The most common location is in parotid region. Clinically, gradual growth and firm consistency are seen. They account for 1 to 3% among all salivary gland neoplasms. Prominent basaloid cells with cluster of isomorphic cells and interspersed trabeculae are present histopathologically. In this article, we present a rare case of basal cell adenoma of retromolar region from minor salivary gland origin.

Salivary gland neoplasms represent less than 3% of all tumors in the general population of which benign adenomas account for 65.5%. Basal cell adenoma which is classified as a subtype of monomorphic adenomas accounts for 1-2% of all salivary gland epithelial tumors, and more than 80% of them arise in the major salivary glands, mostly the parotid gland and has female predominance reporting mostly in the elderly age groups. We here report a case of basal cell adenoma of trabecular type in a male patient of age 45 years in the minor salivary glands of left posterior palatal region...
