[Examination of Breast Cancer in the Super-Elderly Individuals(85 Years Old and Above)at Our Hospital].

The rate of aging in Japan has currently exceeded 28.1%. Moreover, it is expected that the rate of aging will continue to increase in the future. Under these circumstances, the opportunities to treat breast cancer in the super-elderly individuals are elevating. Here, we summarized and examined the cases who were 85 years or above in age and diagnosed with breast cancer at our hospital during the last 10 years. There were 29 cases(30 breasts), who were all female, with an average age of 89.6 years. Dementia coexisted in 17 cases, and an enlarged mass was the trigger for the discovery in most cases. For breast cancer in super-elderly females, it is necessary to treat it in the right proportion. Moreover, it is considered that the treatment policy should be decided considering the presence or absence of dementia and comorbidities. Also, the treatment regime should be decided upon full consultation with the surroundings, such as family members and long-term care facilities.

Coexistence of Spontaneous Pneumomediastinum and a Parapharyngeal Space Tumor: A Case Report of a Patient Initially Referred for Descending Necrotizing Mediastinitis.

Spontaneous pneumomediastinum is conventionally defined as a disease that does not result from trauma or underlying disease. In recent years, many patients have had some kind of triggering factor, such as sports or a strong cough. Herein, we report a case of mediastinal emphysema with a parapharyngeal tumor at the time of initial examination. Although the patient was referred to our hospital on suspicion of cervical abscess such as descending necrotizing mediastinitis by symptoms, it seemed that the cause was a spontaneous pneumomediastinum associated with a parapharyngeal tumor coincidentally. The pneumomediastinum resolved day by day, and the parapharyngeal tumor was extracted without recurrence, which turned out to be a pleomorphic adenoma. As far as we are concerned, there have been no reports of spontaneous pneumomediastinum associated with a parapharyngeal space tumor.
