Six examples demonstrate the reactivation of pulmonary tuberculosis in elderly patients. In 3 cases the tuberculosis became reactivated 25, 47 and 51 years respectively after the initial diagnosis. In aged patients with pulmonary symptoms and abnormal x-ray findings, the presence of reactivated tuberculosis should always be considered. Sometimes steroid or x-ray therapy for other disease may be the reactivating factor.
A 71-year-old woman had massive pulmonary metastases from a right hypernephroma, as shown by a chest roentgenogram. Nine days after nephrectomy, there was no roentgenographic evidence of such metastases. This represents the most rapid regression of clear-cell pulmonary metastases ever reported. Metastases reappeared six months postoperatively and the patient died of widespread metastatic disease 18 months after nephrectomy. The unpredictable behavior of metastatic hypernephroma is discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
