ABSTRACT

BACKGROUND: The worldwide incidence of squamous cell carcinoma of the tongue (SCCOT) in young patients has been increasing. We investigated clinicopathologic features of this unique population and compared them with those of SCCOT in the elderly to delineate its pathogenesis.METHODS: We compared clinicopathological parameters between patients under and over 45 years old. Immunohistochemical assays of estrogen receptor, progesterone receptor, androgen receptor, p53, p16, mdm2, cyclin D1, and glutathione S-transferase P1 were also compared between them.RESULTS: Among 189 cases, 51 patients (27.0%) were under 45 years of age. A higher proportion of women was seen in the young group, but was not statistically significant. Smoking and drinking behaviors between age groups were similar. Histopathological and immunohistochemical analysis showed no significant difference by age and sex other than higher histologic grades observed in young patients.CONCLUSIONS: SCCOT in young adults has similar clinicopathological features to that in the elderly, suggesting that both progress via similar pathogenetic pathways.

ABSTRACT

Popliteal venous aneurysms can be a cause of fatal pulmonary thromboembolism. We report a case of a 47-year-old woman who suddenly died of fatal pulmonary thromboembolism. Deep vein thrombosis was not observed, but a venous aneurysm with intraluminal thrombi formation was identified on the left popliteal vein. This case illustrates that venous aneurysms can be presented as fatal pulmonary thromboembolism, and that they should be considered as a rare cause of pulmonary thromboembolism.
