Intratumoral lymphoid hyperplasia in a patient with lipoma is rare, and when this intratumoral lymphoid hyperplasia occurs as a well-defined, nonadipose mass juxtaposed with a fatty tumor, it may mimic a dedifferentiated liposarcoma. The current opinion is that most, if not all, such cases represent extranodal marginal zone B-cell lymphomas masquerading as reactive lesions.
