LIPOTHYMOMA WITH RED-CELL APLASIA, HYPOGAMMAGLOBULINEMIA, AND LICHEN-PLANUS

We describe a patient who had lipothymoma with red cell aplasia, hypog ammaglobulinemia, and lichen planus. Parathymic syndromes described in association with lipothymomas also include myasthenia gravis, hyperth yroidism, lymphangioma, aplastic anemia, chronic lymphocytic leukemia, and Hodgkin's disease. The behavior of lipothymoma is generally benig n, although local recurrence was noted in 1 patient who had an incompl ete resection. Lipothymoma should be considered in the diagnosis of me diastinal tumors and parathymic syndromes, and also in patients with c ardiomegaly, phrenic nerve palsy, and a widened mediastinum.
