title: Leiomyosarcoma of the orbit: diagnosis of its recurrence by fine-needle aspiration cytology.
abstract: An 8 1/2-yr-old boy with proptosis was diagnosed to have low-grade leiomyosarcoma of the orbit following lateral orbitotomy and histology of an incompletely excised intraconal mass. He received chemotherapy but had recurrence of proptosis at the age of 12 yr. Ultrasonography revealed a solid mass and its fine-needle aspiration cytology features were consistent with recurrence of leiomyosarcoma. A year later, the cytodiagnosis was confirmed by histology of the excised tumor from a second lateral orbitotomy. Masson's trichrome stain confirmed the smooth muscle nature of the neoplasm and ultrastructural features were in favor of leiomyosarcoma. The patient received intermittent chemotherapy, and is clinically free from disease at the age of 17 yr.
