Conjunctival Leiomyosarcoma

A 60-year-old lady presented with a fleshy mass at the nasal limbus of the right eye of two months' duration which was progressively increase in size. Right eye examinations showed a fleshy exophytic mass arising from inferonasal limbus with the base involving cornea and conjunctiva. There was presence of few big feeder vessels at medial part of the mass. The mass had keratinized surface and bled easily on palpation. Excision of the mass was performed in order to rule out conjunctival squamous cell carcinoma. Histopathological examination of the mass revealed malignant spindle cells arranged in interlacing bundles with prominent nucleoli, abundant eosinophilic cytoplasm and atypical mitotic activity. There were positive immunohistochemical staining for actin, vimentin and S-100. The histopathological features were consistent with leiomyosarcoma of the conjunctiva. There was no sign of recurrence at 5 month post excision.
