Nasopharyngeal carcinoma with dermatomyositis.
From 1976 to 1986, ten out of 1154 consecutive nasopharyngeal carcinoma (NPC) patients were found to have dermatomyositis (DM). Their clinical features and treatment results were analyzed. The skin manifestation was typical of DM and myopathy occurred in seven patients. All the tumor on presentation were early stage and locoregional control after radiotherapy was satisfactory. All but one patient had DM prior to diagnosis of NPC. The prognosis of NPC was not affected by DM with survival being comparable to contemporary controls. The complication of radiotherapy were unusually severe. Chronic radiation skin ulceration occurred in 2 patients and subcutaneous indurated fibrosis affecting both sides of neck occurred in all patients. Acute radiation mucositis was also prominent.
