ABSTRACT
Lymphoepithelial carcinoma (LEC) is a rare entity of malignancy. It has been associated with Epstein-Barr virus (EBV), and in regions where it is endemic, such as Southeast Asia, EBV is typically associated with nasopharyngeal carcinoma. The incidence of such malignancies in the young population is unusual. Here we report a 17-year-old with a 5-year history of a painless right submandibular mass presenting with a sudden increase in size for one month before surgery. Neck examination revealed a firm right submandibular gland measuring five by five cm, with an irregular surface, non-tender with normal overlying skin. We performed a fine needle aspiration cytology (FNAC), and he underwent computed tomography (CT) scan of the neck. He underwent a right submandibulectomy. Lymph nodes from levels I and II were also removed. The final histopathology was reported as LEC. Following this tissue diagnosis, another follow-up surgery, a modified radical neck dissection, was carried out for locoregional clearance. Postoperatively, he completed chemoradiotherapy treatment and is now on regular follow-up.
ABSTRACT
Metastatic renal cell carcinoma (RCC) presenting with multiple deposits in the head and neck region is unusual. It is not uncommon for a RCC to metastasise to a distant site after years of a tumour-free period, but most of it would be expected to have a single site of deposit. We report a rare case of a patient who had a nephrectomy 10 years earlier for RCC and presented with tumours in the frontal sinus and posterior pharyngeal wall. Radiological imaging and histology confirmed metastatic RCC at both sites.
