ABSTRACT

Rhabdomyosarcoma is a soft tissue tumour of undifferentiated mesenchymal cells that commonly occurs in the paediatric age group, particularly the embryonal subtype. Pleomorphic rhabdomyosarcoma usually occurs in an adult. On the other hand, alveolar rhabdomyosarcoma can affect all age groups. The common site of alveolar rhabdomyosarcoma is mainly the extremities. Embryonal rhabdomyosarcoma usually affects the head and neck region as well as the genitourinary tract. Only 10% of overall rhabdomyosarcoma involved the orbital region. Imaging features of rhabdomyosarcoma may not be specific; however, early suspicion based on radiological imaging may help in the patientís management and treatment course. We report a rare case of orbital rhabdomyosarcoma, an alveolar subtype in a 54 year-old-woman. The aim of this case report is to discuss the clinicopathological features of this type of tumour in an adult.
