  Fig. 1 (A) Clinical appearance of the mass: The mass presented on the left upper palpebral conjunctiva, showing reddish and firm characteristics. (B) Shave biopsy of the mass: The mass was dissected with shave biopsy and was 8 mm in diameter. (C) A nodular mass measuring 0.8 cm in its greatest dimension with tenting squamo-columnar epithelium was noted (H&E, ×10). (D) The mass was composed of interlacing spindle cells with scanty myxoid stroma (H&E, ×100). (E) The tumor cells disclosed mild to moderate cellularity and mild nuclear pleomorphism. Only one mitosis was identified in the whole field (inlet) (H&E, ×400). (F) Alcian blue special staining revealed scanty amount of stromal mucin in contrast to the cytoplasmic mucin of the intraepithelial goblet cells (×100). (G) Immunohistochemical staining of tumor cells disclosed diffuse and strong positivity for CD34 (×100). (H) The immunohistochemical stains were negative for smooth muscle actin (×100). (I) C-kit immunohistochemical staining was only reactive in mast cells (×100). Written informed conset was obtained from the patient for publication of this case report and any accompanying images. (J) A remnant mass 5 mm in diameter was noticeable. (K) Clinical appearance of the patient 2 months after the shave biopsy: proliferation of the remnant mass was found, and the mass measured 6 mm in diameter.
