Abstract

|
|
Purpose: We report a conjunctival myxoid stromal tumor (CMST), which is a rare benign conjunctival mass.
Case summary: A 70-year-old man with a history of hypertension and cerebral infarction visited our hospital with a clear mass of the conjunctiva in the left eye. His visual acuity was normal, and no other abnormal findings were noted. A transparent, yellowish, jelly-like, 4 × 3 mm mass with a clear border between it and the surrounding tissue was found at the lower temporal part of the conjunctiva. The mass was mobile and there was no pain or tenderness. Excisional biopsy was performed on the mass. Histopathological examination showed reticular fibers located in an abundant mucus-like matrix with fusiform, astrocytic and scattered inflammatory cells. Immunologic examination revealed CD34 positive and SMA negative findings and we diagnosed the mass as a CMST.
Conclusions: When there is a clear pale yellow to light pink mass with a clear border and a distinct vascular distribution or pigmentation in the conjunctiva, the possibility of a CMST must be considered. Histopathologic and immunologic examination should be performed through biopsy and evaluation for systemic disease should be performed as necessary.
