Abstract
ABREU PERDOMO, Franklyn Alain et al. Single block orbitectomy in a patient with neurogenic orbital sarcoma. Rev Cubana Oftalmol [online]. 2016, vol.29, n.2, pp. 345-353. ISSN 1561-3070.
Neurogenic sarcoma is a malignant tumor that starts in Schwann cells of the peripheral nerves sheath and is rarely found in the orbit. Here is a 23 year old, male, Caucasian patient, with a history of Type-I Neurofibromatosis, and a left eye fore and lower side displacement of the left eyeball, intense pain and loss of vision for 4 months. A severe proptosis and the lowering of the left eyeball was detected during the ophthalmologic examination, as well as total ophthalmoplegia, severe chemosis, hyperemia, corneal opacity and increased upper eyelid volume. Imaging studies revealed a tumor lesion occupying the whole orbital compartment, with no bone wall infiltration, but causing the displacement of the eyeball out of the orbit border. A combined surgical approach was performed consisting in a single block orbitectomy with total tumor resection, as well as the reconstruction with the ipsilateral temporal muscle rotated flap. The histopathology study showed the presence of an neurogenic orbital sarcoma, so an adjuvant radiotherapy treatment was indicated. The patient was followed up for a year, after which the sequential occurrence of several lesions began.
