Proteus syndrome: ocular complications.

Proteus syndrome is a recently recognized hamartoneoplastic malformation syndrome of uncertain etiology and variable expression, whose cardinal manifestations are pigmented nevi, hemihypertrophy, macrodactly, lipomata, and cerebroid-gyriform configuration of the skin on the soles of the feet. The characteristic features may be present at birth but become more apparent with time. In the past this syndrome has been confused with other overgrowth disorders such as neurofibromatosis, Klippel-Trenaunay-Weber syndrome, Maffucci syndrome, and Bannayan syndrome. The ophthalmic features of the proteus syndrome require clarification. We review the ocular findings in 16 previously described cases and describe the findings unique to our patient, in particular, unilateral epibulbar and suspected posterior segment hamartomas.
