RESUMO
Primary mucosal melanoma of the tonsil is rare, with 27 reported cases. Careful diagnosis is necessary, as the tonsil is more often a site of metastatic melanoma from a cutaneous primary tumour. In this report, we present a case of primary right tonsillar mucosal melanoma with widespread metastasis in a 31-year-old man who presented with a 3-month history of enlarging neck lumps. On examination, he had cervical lymphadenopathy and a pigmented, vascular lesion of his right tonsil, which was diagnosed as melanoma following investigation. He had widespread metastases upon presentation, and is currently undergoing palliative immunotherapy. Owing to the aggressive behaviour, late presentations and lack of effective treatment to cure mucosal melanomas, they have a poor prognosis. Treatment involves wide local excision in local disease, and immunotherapy as the first-line for metastatic disease.
RESUMO
Mucoepidermoid variant of thyroid carcinoma is a rare and complex disease. Securing a diagnosis and formulating an evidence-based treatment plan is challenging. A case report of a patient with the dual pathology of a composite mucoepidermoid carcinoma of the thyroid and a follicular variant of papillary thyroid carcinoma with malignant metastasis is presented in this article. We discuss the challenges in diagnosis, prognostic factors and management of this rare presentation by reviewing current literature.
RESUMO
BACKGROUND: Ring retractors, such as the Alexis® wound retractor, are simple devices used in a wide range of surgical settings to provide atraumatic exposure while protecting wound edges. METHODS: Here, we describe the application of the Alexis® to provide access during transoral robotic surgery (TORS). CONCLUSION: Its ease of application and many benefits, including maximization of intraoral space and protection of perioral soft tissues, make this device an excellent adjunct for TORS procedures.
