A wolf in sheep's disguise: rhabdomyosarcoma misdiagnosed as infantile hemangioma.
BACKGROUND
Rhabdomyosarcomas are a heterogeneous group of malignant tumors representing the most common soft tissue sarcoma of childhood. A delay in diagnosis is not uncommon.


OBJECTIVE
To report a boy with paranasal rhabdomyosarcoma who was misdiagnosed and treated for infantile hemangioma.


RESULTS
A 2-year-old Saudi boy who presented with a progressively increasing nasal mass for 18 months was misdiagnosed and treated for infantile hemangioma at an outside hospital. Histopathologic examination revealed paranasal rhabdomyosarcoma.


CONCLUSIONS
We review some clinical clues that can alert the physician to malignant childhood tumors. We also review management options for childhood rhabdomyosarcoma.
