A Case of Nodular Muscular Sarcoidosis Mimicking a Tumor / 대한내과학회지

The nodular form of muscular sarcoidosis is a rare malady that is often confused with a soft-tissue neoplasm or other lesion. Here, we present a case of nodular muscular sarcoidosis in the arms and legs of a 59-year-old woman. She presented at our hospital with a painless nodule in her left arm. Excision was performed and she was diagnosed with sarcoidosis. One year later, nodular sarcoidosis recurred in her arms and legs. After 2 months of steroid medication, the nodules disappeared. The patient has been followed for 2 years and no evidence of recurrence has been observed.

Electrocardiographic changes suggesting ischemic heart disease in a case of lung cancer with myocardial metastasis / 대한내과학회지

Metastatic tumors to the myocardium proper are uncommon and difficult to diagnose because they have nonspecific signs and symptoms. Electrocardiogram (ECG) changes mimicking ischemic heart disease often develop when non-conducting tumor tissue replaces cardiac muscle. Hence, a high level of suspicion is required to differentiate ECG changes caused by myocardial metastasis from those caused by coronary heart disease in cancer patients. We describe a case of primary lung cancer with myocardial metastasis that showed diffuse ST segment elevation and T wave inversion on the ECG, with a relevant literature review.
