case_images: Physical examination showed mild swelling of the left eyelid and a yellowish subconjunctival mass in the superior bulbar region, which had a soft consistency, was non-reducible, and had no apparent posterior limit (Figures 1 and 2). The globe was displaced inferiorly by 5 mm (Figure 1), and proptosis of 5 mm was observed in the left eye.
case_images: A yellowish subconjunctival mass is visible in the superior bulbar area of the globe.

case_images: Magnetic resonance imaging of the brain and orbits demonstrated a soft tissue mass with dimensions of 1.1x1.6 x 1.7 cm involving the superior rectus muscle belly and tendon (Figures 3 and 4).

case_images: Magnetic resonance imaging of the brain and orbits demonstrated a soft tissue mass with dimensions of 1.1x1.6 x 1.7 cm involving the superior rectus muscle belly and tendon (Figures 3 and 4).
case_images: The picture shows the mass progressive growth and prolapse into the palpebral fissure.

case_images: The superior bulbar mass gradually enlarged and prolapsed in the palpebral fissure over 4 months (Figure 5).
case_images: Hematoxylin and eosin (H&E) (1x) Whole mount section of the orbital mass demonstrates an encapsulated adipose tissue mass, with foci of lymphoid aggregates.

case_images: A pathological study revealed mature adipose tissue, with minimal connective tissue stroma, enclosed in a thin fibrous capsule (Figure 6).
case_images: H&E (40x) The light microscopic picture of tenon capsule shows high-power field findings of lymphoid aggregate which is composed of polymorphic lymphoid cells and plasma cells, without definite evidence of granuloma and vasculitis.
