A 67-year-old woman presented with progressive enlargement of a long-standing mass on the surface of her OS associated with ocular surface irritation. The mass was excised en bloc. Histopathological examination showed a well-defined encapsulated tumor composed of wiry collagen containing bland spindle cells that were strongly positive for CD34 with scattered mature adipocytes. These features confirmed a diagnosis of spindle cell lipoma.
