Conjunctival Leiomyosarcoma: A Report of Two Cases

Area of Science:

• Ophthalmology
• Oncology
• Pathology

Background:

• Leiomyosarcoma is a common soft tissue tumor.
• Ocular leiomyosarcoma, specifically conjunctival leiomyosarcoma, is exceptionally rare.

Observation:

• Two cases of conjunctival leiomyosarcoma are presented, detailing clinical and histopathological features.
• One patient had a large mass with orbital extension requiring exenteration; the other had a limbal mass treated with plaque radiotherapy.

Findings:

• Histopathological examination confirmed leiomyosarcoma in both cases.
• Both patients experienced no tumor recurrence or systemic metastasis at one-year follow-up.

Implications:

• Primary conjunctival leiomyosarcoma is an uncommon diagnosis.
• Timely and appropriate treatment of conjunctival leiomyosarcoma is associated with a good prognosis.
