Conjunctival myxoma is a rare benign tumor, which can mimic more common conjunctival lesions such as a cyst, lymphangioma, amelanotic nevus, neurofibroma, amelanotic melanoma, or lipoma. We describe a patient with the conjunctival myxoma, who was initially misdiagnosed as a conjunctival cyst. This case report includes intraoperative photographs and various immunohistochemical staining images.

Patients concerns:

A 55-year-old woman presented with a painless mass in the superotemporal conjunctiva of the left eye, which she had noticed 1 month ago. The patient had no previous history of trauma or eye surgery. Slit-lamp examination revealed a well-circumscribed, freely movable, pinkish, semi-translucent mass on the temporal bulbar conjunctiva, suggestive of a conjunctival cyst.


Histopathological analysis showed stellate- and spindle-shaped cells within the loose myxoid stroma, confirming a diagnosis of conjunctival myxoma.


The conjunctival lesion was completely excised under local anesthesia.


After 4 months of follow-up, the patient remained in good health without recurrence of the conjunctival lesion and no evidence of any systemic abnormality.


Myxoma is an extremely uncommon benign tumor derived from primitive mesenchyme. Considering the rarity of the tumor and its similarity to other conjunctival tumors, diagnosis can be challenging. Ophthalmologists should consider myxoma as a possible differential diagnosis when encountering conjunctival lesions. Surgical excision is essential to confirm the diagnosis and careful systemic evaluation is required to prevent potentially life-threatening underlying systemic conditions.
