This report is concerning a case of adenosquamous carcinoma having unknown origin and showing SVC syndrome as the first symptom. A 44 year-old man was admitted to our hospital because of facial edema at the beginning of April 1990. He was diagnosed as having a mediastinal tumor of the SVC syndrome type. ⋯ The pathological diagnosis of the SVC tumor was adenosquamous carcinoma, however, no clinical examinations could identify its original matrix. Mediastinal tumors of unknown origin are reported as about 1% of all mediastinal tumors, and are responsible for 0.68% of all carcinomas in the mediastinum. This was one experience of a rare case of mediastinal tumor having unknown origin and showing SVC syndrome as the first symptom.
