In this paper, we report three cases of orbital rhabdomyosarcoma in different age groups with different
histopathologic types. Case 1 is a 10-year old Malay boy who presented with painless proptosis of the
left eye. Magnetic resonance imaging (MRI) showed soft tissue mass arising from the lateral rectus
muscle. Tissue biopsy revealed rhabdomyosarcoma of embryonal type. Case 2 is a 32-year old Malay
man who presented with a progressive left eye proptosis associated with pain and redness. Computed
Tomography (CT) scan showed a retrobulbar mass extending medially in the left orbit. Meanwhile,
biopsy showed rhabdomyosarcoma of pleomorphic type. Case 3 is a 67-year old Malay woman who
presented with proptosis and fungating growth of left orbital region, epistaxis and nasal blockage. CT
scan revealed an ill-defi ned mass fi lling up the left orbital cavity. Biopsy showed rhabdomyosarcoma
of alveolar type. Rhabdomyosarcoma is the most common in childhood but it should be considered
as a differential diagnosis of orbital tumours irrespective of age.
