We report three cases of proptosis, in children
aged 6, 10 and 12, whereby in all cases
the first clinical, radiologic and ultrasonographic
diagnosis was lymphangioma, while
the final anatomopathological diagnosis was
rhabdomyosarcoma. In presence of a rapidly
worsening exophthalmos or eyelid swelling in
a child, an early correct diagnosis is very
important. Imaging techniques play a very
important role in the diagnosis, but are often
inconclusive and an excisional biopsy (if feasible)
must always be considered
