Purpose

To present a case of nasosinusal chondrosarcoma revealed by a Periorbital edema.

Setting

Adult Ophtalmology Department of 20 August University Hospital, Casablanca, Morocco

Methods

A 25-year-old patient, with no particular pathological history, presented for significant periorbital edema of the left eye. Facial examination revealed a facial asymmetry, a widening of the base of the nose and a fullness of the medial canthus of the left eye. Ophthalmologic examination of the left eye revealed an impossible spontaneous eye-opening, a grade II exophthalmos and a normal fundus exam. Ophthalmologic examination of the right eye did not show any abnormalities. The patient was conscious, with no sensory-motor deficit.

Results

CT of the sinuses showed a mass lesion involving the nasal cavity and the left maxillary sinus with bone lysis and expansion to the nasopharynx and the left orbit. The biopsy of the nasal cavity concluded through the histological study to a sarcoma. The immunohistochemical study confirmed the diagnosis of chondrosarcoma. After 4 cycles of neoadjuvant chemotherapy, a complete removal of the tumor was performed with an additional external radiotherapy. The histological study was in favor of a chondrosarcoma grade II.

Conclusion

Chondrosarcoma of the paranasal sinuses is a rare and aggressive tumor with a slow growth. The occurrence of a significant periorbital edema associated with uni or bilateral nasal obstruction justifies the use of Facial imaging.
