Juvenile nasopharyngeal angiofibroma. An unusual presentation as an oral mass.

Although juvenile nasopharyngeal angiofibroma (JNAF) usually presents as a mass in the nasopharynx, the primary manifestation may, in rare instances, occur intraorally. We observed such a case in a 12-year-old boy. The clinical finding of hemorrhage from the nasopharynx or contiguous areas in a male adolescent is an important diagnostic clue which should alert the clinician to the possibility of JNAF as the underlying cause.

Thorotrast-induced extraskeletal osteosarcoma of the cervical region. Report of a case.

This is the seventh reported case of soft tissue sarcoma attributed to thorotrast extravasated during the course of an injection for arteriography. An extraskeletal osteosarcoma occurring the cervical region of a 51-year-old man 30 years after a cerebral arteriogram is presented. The other reported cases include a fibrosarcoma, two neurofibrosarcomas, two spindle cell sarcomas, and an extraskeletal chondrosarcoma. The latency period has varied from 5 to 30 years. The thorotrast granules are readily identified in macrophages near or adjacent to the tumor, and the demonstration of alpha tracks on autoradiographs is diagnostic.
