Advantages of Intraoperative Neuromonitoring Over Direct Visualization of the Recurrent Laryngeal Nerve During Thyroidectomy.

Background: The well-recognized risk of injury to the recurrent laryngeal nerve (RLN) during thyroidectomy has instigated various preventive measures. One such measure involves directly visualizing the RLN, but this is not always feasible in practice. A more recent approach involves using intraoperative neuromonitoring to identify and preserve the RLN.

Warthin's Tumor of the Parotid Gland With Degeneration to Diffuse Large B-cell Lymphoma: A Case Report and Review of Literature.

Parotid gland neoplasms are rare; some benign lesions, such as Warthin's tumor (WT), can present as malignant degeneration to carcinomas or, even rarer, to lymphomas. In the literature, there are fewer than 30 reported cases of primary lymphoma of the parotid gland. We present a case of a 65-year-old male patient with a first diagnosis of WT of the parotid gland who later presented a tumor recurrence and underwent a second surgery, reporting diffuse large B-cell lymphoma of the parotid gland.
