Conjunctival Stromal Tumor

A 66-year-old woman developed a 4 ×8-mm slow-growing, buff-colored mass of her left conjunctiva over 5 years. The lesion was firm, fixed to underlying tissue, and straddled the limbus eccentrically (Fig 1A). Biopsy showed the substantia propria replaced with a pauci-cellular tumor, consisting of delicate spindle cells separated by bundles of collagen and scattered blood vessels (Fig 1B). The spindle cells expressed CD34 (Fig 1C) and vimentin. The diagnosis of conjunctival stromal tumor describes a CD34-positive benign mesenchymal tumor with matrix varying from purely myxoid to purely collagenous.
