Orbital Lymphangioma Dear Editor: I read with interest the recent report by Vavvas et al1 regarding the coexistence of congenital orbital and intraocular vascular abnormalities. The 2 cases they describe are strikingly similar to a case2 I reported with Sam Rahim in 2001 in which a young girl had a biopsy-proven orbital lymphangioma, mild microcornea, an unusual large iris vessel, and an atypical retinal vessel branching pattern. I suspect the authors were unaware of our case report, because it is not referenced on MEDLINE. Dr Rahim and I reached the same conclusion as Vavvas et al—to wit, that this combination of malformations is due to a localized disruption of vascular anlage maturation. SANDRA M. BROWN, MD Lubbock, Texas,

Author reply Dear Editor: We thank Dr Brown for bringing our attention to her case report and for highlighting the limitations of a MEDLINE literature search. We, too, were struck by the similarities linking these independent reports. However, we cannot concur that the findings in any of the 3 cases represent persistent fetal vasculature, as the title of Dr Brown’s case report indicates. Nevertheless, the coexistence of these blood vessel and lymphatic anomalies leads all of us to reach the same conclusion: that they result from a localized disruption of common vascular anlagen.
