Leiomyosarcoma is the most common soft tissue sarcoma and is described as a malignant tumor of mesenchymal cells. It is rarely found as primary, secondary, or metastatic in origin in the eye and adnexa. To the best of our knowledge, a metastatic leiomyosarcoma involving the conjunctiva has not been reported in the literature. We report a case of a 35-years-old gentleman, with a prior history of leiomyosarcoma involving the anterior chest wall with pulmonary metastasis presenting to us with a rapidly increasing conjunctival mass involving his left eye. After a detailed clinical evaluation, the lesion was surgically excised. We discuss the clinical features and histopathology characteristics supported by immunohistochemistry analysis of this rare case of conjunctival metastasis from leiomyosarcoma with a review of metastatic tumors of the conjunctiva.
