[Coincidence of Lipoma and Liposarcoma of the Right Hand in an 84-Year-Old Patient: A Case Report].
Summary. We report the case of an 84-year-old patient presenting with a painless tumor between the thumb and the index finger. MRI showed a clearly defined tumor of the thenar eminence with a centrally localized more solid structure. There was a signal enhancement after intravenous administration of contrast medium. We performed a local resection of the tumor. Histologically, we found a lipoma with a centrally localized liposarcoma. We discuss the rare case of malignant transformation of a lipoma. In long-standing large lipomas we suggest regular controls by MR imaging.
