title: Mycosis fungoides of thyroid diagnosed by fine needle aspiration.
abstract: Fine needle aspiration of a poorly defined thyroid nodule in a patient with mycosis fungoides revealed convoluted mononuclear cells consistent with involvement by mycosis fungoides. I have briefly reviewed the literature on extracutaneous involvement, and discussed the potential usefulness of fine needle aspiration studies in diagnosing visceral or lymphatic mycosis fungoides.
