The orbital rhabdomyosarcoma is the most common primary malignant tumor of the orbit in childhood. It was first described in 1854 by Weber and has been increased possibly due to improvement of diagnostic procedures. A 7-year-old boy with the complaints of proptosis and visual disturbance coincidently had an ocular trauma. Incision and drainage of intraorbital hematoma was performed in the right orbit which was confirmed with orbital CT scan. Microscopic findings showed ovoid and spindle shaped rhabdoblasts, hyperchromatic nuclei, and characteristic cross striation in the cytoplasm of the giant cells. He was diagnosed as embryonal rhabdomyosarcoma. The intraorbital hematoma and surrounding tissue in the right orbit were excised and the right eye was enucleated. He received chemotherapy and radiation therapy.

Sixteen multiple primary carcmomas were found in 674 patients with gynecologic malignancies who were treated in our departiment from 1980 to 1992. Cases with possible metastasis or recurrence were not included in this study, The incidence of rnultiple primary carcinomas in gynecologic rnalignancies was 2.1%, Multiple primary carcinomas were encountered in 2.4% of 674 cervical cancers, 1.4% of 73 ovarian cancers respectively. The most frequent sites of uther cancers were seen in the stomach(5/16) and lung(3/l6).
