[Lipomatous pleomorphic adenoma of the parotid].
Lipomatous tumors rarely occur in the salivary glands. We report an unusual case of lipomatous pleomorphic adenoma in a 47-year-old man. The patient had no significant medical history and presented with a well circumscribed nodule measuring 3 cm in the right parotid. Histologically, the tumour was predominantly composed of sheets of mature fat cells. Rare myoepithelial cells and exceptional tubules were intermingled with the mature adipose tissue. One year after surgery the patient was alive without recurrence. In conclusion, it is a rare neoplasm who needs to be recognized and discussed with true fatty tumors and lipomatosis.
