Abstract
-
Cancer-associated rheumatic disorders are sometimes present concurrently with a tumor, but are not recognized initially. We report a case of dermatomyositis with breast cancer. A 46 year-old woman diagnosed with breast cancer with axillary lymph node metastasis had been treated by neoadjuvant chemotherapy and a lumpectomy with axillary lymph node dissection. She presented with a red rash on her face, eyelids, neck, and shoulders. A skin biopsy did not rule out dermatomyositis. Laboratory values were within normal limits, except muscle enzymes (Creatine kinase). Electromyography showed the presence of early myopathy. A PET CT-scan showed muscle uptake in left infraspinatus, r/o myositis. No abnormalities were presented in the muscle biopsy. Symptoms were improved by steroid therapy.
