We report a case of lipoma arising in the parotid gland. A 62-year-old man presented with a swelling in the left preauricular region, which had persisted for two months. The tumor was soft and the size of a hen's egg, with no tenderness. Sialography revealed a so called ball-in-hand appearance, which suggested a benign tumor. CT scan demonstrated a clear-cut low density area showing -104.3 Hounsfield units. The tumor was extirpated easily. The diagnosis of lipoma was made histologically.
