Degenerative apparent anophthalmia with complex choristoma of orbit. A clinicopathological case report.

A case of a peculiar congenital mass in the left orbit is described in a 6-year-old girl from Thailand. The most appropriate name for this malformation, which we have not found described in the literature, seems to be 'degenerative apparent anophthalmia with complex choristoma of the orbit'. Some unknown environmental influence is suggested.
