ABSTRACT
Minimally invasive surgery has been adopted in many areas of surgery to reduce patient morbidity during surgical resection. To achieve this, endoscopic instrumentation coupled with improved imaging and localisation techniques have been developed, to enable adequate resection of tumours with minimum damage to surrounding tissues. We review two emerging technologies, robotic assisted surgery and intraoperative imaging. We also discuss two fields of head and neck surgery, skull-base tumour resection and thyroidectomy, where the application of minimally invasive endoscopic techniques has been widely applied, and review their results.

Kimura's disease is a fairly uncommon inflammatory condition of unknown etiology. It classically presents in young Asian males as tumorlike subcutaneous nodules in the head and neck with associated lymphadenopathy, peripheral eosinophilia, and an elevated serum IgE level. Kimura's disease affects the subcutaneous tissues, salivary glands, and lymph nodes; less common sites in the head and neck include the eyelid and tympanic membrane. We report a case of Kimura's disease of the parapharyngeal space in a 42-year-old Chinese woman. To the best of our knowledge, this is the first report of Kimura's disease at this site.

Epithelioid angiosarcoma involving the thyroid is a rare entity, more often described in the Alpine region. Two cases of epithelioid angiosarcoma that affected the thyroid in patients from a non-Alpine location were diagnosed during a 10-year period in our department. The first case occurred in an 89-year-old Chinese man with a history of longstanding goiter, whereas the second case involved a 74-year-old Chinese man with a history of angiosarcoma of the scalp. On histologic examination, both thyroid tumors were composed of plump epithelioid cells with vesicular chromatin and prominent nucleoli, forming vascular structures and solid sheets. Positive staining for CD31 and factor VIII-related antigen confirmed endothelial differentiation in both cases. Both patients died within 5 months following the diagnosis of thyroid disease. The relationship of the scalp angiosarcoma and thyroid disease of the second patient is unclear. A brief review of non-Alpine primary thyroid epithelioid angiosarcoma is presented.
