A 76-year-old man had complained of dacryorrhea and visited a hospital, where he was diagnosed with primary ductal adenocarcinoma of the right orbital region based on an excisional biopsy. Radiotherapy was administered. After one year, dark reddish macular lesions appeared on the right side of his neck and gradually increased in size. At the first consultation in our hospital, angiosarcoma was suspected from the clinical findings. Histopathological analysis revealed skin metastasis of the primary ductal adenocarcinoma. Taken together, the extensive erythema of the neck was diagnosed as carcinoma erysipelatodes. An imaging examination demonstrated right cervical lymph node metastasis, multiple bone metastases, and lung metastasis. Radiotherapy and chemotherapy were administered. The skin symptoms remarkably improved and the dysphagia was also relieved with these therapies. Only a few reports have been published describing primary ductal adenocarcinoma of the right orbital region ; cases of skin metastasis, such as ours, have rarely been reported.[Skin Cancer (Japan) 2018 ; 33 : 7-12]
