case_images: Left upper eyelid saucer-shaped mass with inhomogeneous content on T1-weighted axial image (arrow, A) and T2-weighted axial image (arrow, B) of magnetic resonance imaging. Left upper eyelid subcutaneous flat mass with 2 x 2.5 cm in size at surgery (C) and macroscopic view of the extirpated mass with size reference of no. 15 curved blade (D). Note incision line and area of the mass are marked on the skin at surgery by local anesthesia (C). Collagen fibers, capillaries and small vessels, and spindle cells in small number which are dispersed among mature adipose tissues with varying sizes (E in low magnification, F in high magnification). Spindle cells are positive for CD34, supporting the diagnosis of spindle cell lipoma. Bar = 1000 mum in E, 200 mum in (F and G).

case_images: Magnetic resonance imaging (Figure 1A,B) showed a well-defined, saucer-shaped mass with inhomogeneous content of mixed lipid and water in the left upper eyelid on the temporal side with probable adhesion to the orbital bony edge. With the clinical diagnosis of a dermoid cyst, the patient underwent the extirpation at local anesthesia (Figure 1C). The saucer-shaped mass (Figure 1D) was located anterior to the orbital septum and had firm adhesion to the supero-temporal orbital bony edge. The pathological examination of the mass showed that collagen fibers, capillaries and small vessels, and spindle cells in small number were dispersed among mature adipose tissues with different sizes (Figure 1E,F). The spindle cells were positive for CD34 (Figure 1G), indicative of spindle cell lipoma.
