Tumor metastasis into skeletal muscle is uncommon, and is rarely noticeable clinically. Lung cancer and gastrointestinal tumors are the most frequent primary malignancies that metastasize to the skeletal musculature, but some reports have described muscle metastases from breast cancer [1]. The authors present a case of gluteal muscle metastasis in a patient with a known primary breast cancer. A...

OBJECTIVES To assess the association between muscle invasion by oral squamous cell carcinoma of the posterior mandibular alveolar ridge and cervical lymph node metastasis on the basis of preoperative magnetic resonance imaging (MRI). MATERIALS AND METHODS Twenty-six patients with oral squamous cell carcinoma of the posterior mandibular alveolar ridge were evaluated by MRI. The associations be...

Asymptomatic skeletal muscle metastasis in non-small cell lung cancer is a rare event particularly when it is detected at initial staging. This report describes how whole body imaging with [18F]fluorodeoxyglucose (FDG) positron emission tomography (PET)-computed tomography (CT) detected a solitary asymptomatic metastasis to the gluteus maximus muscle in a potentially resectable case of non-smal...

women and the second most important cause of death from cancer (1). The tumor size, lymph node status, and histological tumor grade of the tumor nuclei are important factors determining the likelihood that metastatic disease develops (2). The primary prognostic factor for breast cancer is axillary lymph node metastasis (3). The significant cause of death in patients with breast cancer is the ne...
