RESUMEN
We report a 12-year-old girl with hyperthyreosis who presented methamazole-induced toxic epidermal necrolysis (TEN). The patient's past history suggests a presence of autoimmune disease. To our knowledge it is the first report describing such an adverse effect of methimazole.

Hypothyroidism is induced in rats treated with thiamazole, an antithyroid drug. If this phase lasts long enough, the follicular cells develop adenomas. Within the same period, the number of parafollicular or C cells increases threefold on an average, but without producing corresponding adenomas, the formation of which is inhibited. When treatment is stopped, a second phase appears during which thyroid function reverts to normal. The previously observed inhibition disappears, and, after a period of latency, the hyperplastic C cells develop parafollicular adenomas. The type of tumors to be found in treated rats (either of them, or both simultaneously) is determined by respective durations of the two phases. The endocrine mechanisms of these phenomena are discussed.
