We present a case with leimoyosarcoma of the conjunctiva and orbit. A 70-year-old male patient who admitted with an exophytic mass covering interpalbepral fissure is presented in this case report. The past medical history was positive for a recurrent mass after two simple excisions with a preliminary diagnosis of pterygium. The orbital tomography demonstrated a 2 x 1.5 x 1.6 cm mass involving cornea. The mass had scleral and medial rectus muscle involvement, as seen intraoperatively. The mass was excised including medial ream muscle (modified enucleation) and the conjunctiva was also excised with a 5 mm tumor-free area. The histopathologic examination confirmed the diagnosis of leimyoscarcoma. Postoperative radiotherapy was administered. Conjunctival involvement is a rare clinical form of orbital leiomyoscarcoma. Atypical conjunctival lesions and recurrent pterygia should be carefully approached and pathological examination should be performed to rule out malignant lesions like leiomyosarcoma.
