Myxomas and Angiomyxomas of the Orbit

Myxomas rarely involve orbital tissue, and no angiomyxomas of the region have been previously reported. Angiomyxomas in children may be aggressive. Vascularity and bone involvement appear to be important prognostic features for recurrence. Complete resection with a margin of healthy tissue appears to be the treatment of choice. Tumor cell immunopositivity for vimentin, CD34, and factor XIIIa may assist in the histopathologic diagnosis.
