title: Rhabdomyosarcoma and late malignant melanoma of the orbit.
abstract: Forty-five years following surgical excision and radiation for a childhood rhabdomyosarcoma of the left orbit, a patient with primary lymphedema developed an ipsilateral malignant melanoma of the anterior orbital tissue. This was excised, but a metastasis of the melanoma occurred in the contralateral upper lid. This is the first case report of treated rhabdomyosarcoma of the orbit followed by a second primary tumor occurring in the field of radiation.
