- Abstract
A 50-year-old woman was diagnosed with dermatomyositis at the department of neurology in our hospital; she then received steroid pulse therapy. A positron emission computed tomography(PET-CT)revealed swollen lymph nodes near the aorta and in the left inguinal region. She presented at our institution for examination to determine the cause of her lymphadenopathy, but the primary site of the carcinoma was unknown. A histopathological examination of the lymph node specimen obtained using endoscopic ultrasonography-guided fine-needle aspiration(EUS-FNA)revealed a moderately to poorly differentiated adenocarcinoma. The patient underwent lymphadenectomy. After the surgery, a new lymph node metastasis appeared in the lower abdomen. We initiated a combination treatment with chemotherapy and radiotherapy. The patient died because of disease progression 31 months after her first visit.
