An 82-years-old man was referred to our hospital for a nodule on the upper right eyelid. He gave a history of bruising his upper right eyelid two weeks earlier. Histopathologically, the lesion was characterized by the presence of foamycells in the dermis and subcutis. We diagnosed the nodule as a tuberous xanthoma. The nodule disappeared spontaneously within three months.
