The fourth case of malignant lymphoma coexisting with an adenocarcinoma in the stomach is presented. Although an increased incidence of systemic malignant lymphoma in association with gastrointestinal tumors has recently been emphasized, primary gastric lymphoma and adenocarcinoma coexisting in the same stomach is still rare.
Extracardiac rhabdomyomas are rare benign lesions of striated muscle origin. A review of the world literature revealed about 27 acceptable cases of benign, adult-type rhabdomyoma with a distinct male predominance. In most of the reported cases, the tumor was located in the head and neck region, usually submucosal or deeper. The case reported here is unusual because the tumor was subcutaneously located in the neck. The tumor was fairly well circumscribed, multilobulated, and easily shelled out. Light microscopy showed large round to elongated cells with granular, highly eosinophilic cytoplasm, often with peripheral vacuolation. Cross striations were infrequent. The nuclei were often peripheral and had prominent nucleoli. Electron microscopic studies confirmed the tumor's myogenic origin. Myofibrils with Z band material, abundant mitochondria, and glycogen particles were observed.
Comparative studies between routine roentgenograms and scintiphotographs using 99mTc-pyrophosphate, of the hands and feet are documented in three cases of bone sarcoidosis. All the abnormal roentgenographic findings were also detected by 99mTc-pyrophosphate bone imaging. However, several areas of increased radiopharmaceutical uptake were found in areas with normal roentgenographic studies. These results suggest that the 99mTc-pyrophosphate bone scintiphotographs might be more sensitive than radiographs in the localization of the bone involvement in sarcoidosis.

Caring for the parenteral drug abuser with infective endocarditis is a challenge. In many ways, the nursing care needed for these patients differs from that needed by other patients with infective endocarditis. This article has identified some of the important considerations: maximizing the effectiveness of the treatment regimen, fostering patient adaptation to hospitalization, and planning for discharge to minimize the risk of recurrence. By understanding the nature of drug abuse and of infective endocarditis, and by understanding how they interact to create a particular set of problems in the parenteral drug abuser with infective endocarditis, the nurse can provide optimal nursing management for these patients.
