Intrathyroidal metastasis of tonsillar squamous cell carcinoma is rare. To date, only six cases have been reported in the literature. This case was unusual and presented with thyromegaly before the diagnosis of the primary tumor. A 55-year-old male patient was suspected to have a primary thyroid tumor with nodal metastasis. The thyroid gland was diffusely enlarged, with no discernible mass. Histologically, the thyroid parenchyma revealed extensive endolymphatic tumor emboli, which were positive for p40 and p16 in a background of chronic lymphocytic thyroiditis. Positron emission tomography–computed tomography revealed hypermetabolic activity in the right tonsillar region. Tonsillar biopsy revealed human papillomavirus–positive squamous cell carcinoma. The present case is the first reported case of intrathyroidal metastasis of tonsillar squamous cell carcinoma with an initial clinical presentation of thyroid enlargement before the primary tumor of tonsillar cancer was diagnosed.

Abstract PDF: BACKGROUND
Because of the rarity of mummies in Korea and the difficulty in obtaining samples from mummies, studies to determine the ages of mummies are uncommon in Korea. This study was performed to determine the ages of mummies using the information obtained by nondestructive methods to minimize damages to the mummies. METHODS: Three mummies excavated between 2002 and 2004 were used. Three-dimensional reconstructed images of the total teeth were obtained by CT scanning. The age at death was determined according to the 'Age Estimation Table of Dental Attrition' as developed by Takei. Three teeth were extracted from each of three mummies and examined grossly and microscopically by serial sections using the Gustafson-Johanson method. RESULTS: The ages at death of the three mummies estimated by the Takei method were 23.57 years (Yoon mummy), 51.01 years (Bong mummy), and 64.45 years (Black mummy). These results were similar to the ages determined by the Gustafson method. CONCLUSION: Age determination method using a CT scan and three-dimensional reconstruction may be a valuable method because it minimizes the damages to valuable mummies and it gives reliable data similar to that obtained by other standard methods.
