The first patient presented complaining of dry itchy skin on her lower legs that was not improving with a moisturiser. On examination, dry skin may be seen in association with eczema, i.e., asteatotic ecema (eczema craquele). Further inquiry determined that she was feeling tired and gaining weight despite poor appetite. The rash resolved with a mild topical steroid ointment and a thicker emollient. Thyroid function tests revealed elevated thyroid-stimulating hormone (TSH) level and free T4 just below the normal range, which was considered significant.
