REFERRING TO DERMATOMYOSITIS

例如眼皮上的向陽疹(Heliotrope sign)、前胸特殊的紅疹(V sign)或者是手部指間關節的紅疹(Gottron sign)。

ans: nasopharyngeal cancer

Dermatomyositis is well known to be associated with several types of malignancy and patients with dermatomyositis have higher rates of mortality from cancer. Although rare in Japan, head and neck cancer, especially nasopharyngeal cancer, is the predominant type of cancer associated with dermatomyositis in several areas in Asia, including Hong Kong and Singapore. Here we report two cases of head and neck cancer with dermatomyositis as well as a literature review. Both cases were treated with chemotherapy and radiotherapy. Although the patients were immunosuppressed due to dermatomyositis treatment, no grade 3 or 4 adverse events occurred.
