title: An infant with Turner-Down aneuploidy and massive capillary hemangioma of the orbit: a case report with review.
abstract: We report on a case of double aneuploidy involving Down and Turner cell lines in a female child with a massive capillary hemangioma of the left orbit and mild clinical features of Down syndrome. Cytogenetic findings with G-banding revealed mosaicism in her peripheral blood, i.e. mos45,X[48]/47,XX,+21[28]/46,XX[12/47,XXX[12]. Mosaicism of such nature is rare and to our knowledge the present case is the first reported of Turner-Down double aneuploidy mosaicism associated with an orbital capillary hemangioma. An annotated bibliography of earlier reported cases with documented karyotyping is also included.
