基于这些发现,lymphocutaneous孢子丝菌病诊断,和碘化钾是规定在1 g / mL;这是开始每天三滴,逐步增加病人容忍金属味。经过一个月的治疗,每天用25滴碘化钾,病人报告缺乏食欲,恶心和呕吐。碘化钾是取代了伊曲康唑,口服药物12天在100毫克/天;随着病人变得宽容,抗真菌药物的剂量增加到200毫克/天。病人报告常数恶心和催吐剂事件经过七天的治疗;然而,水平的丙氨酸和天冬氨酸氨基转移酶,碱性磷酸酶,gamma-glutamyl转移酶是正常的。后五十天的开始伊曲康唑治疗,病人报告严重的胃肠道变化,和静脉注射止吐剂药物胃复安管理病人;不断水化是推荐的。这个事件后十天,没有观察到改善皮肤损伤。 Due to the side effects of both first-line drugs and the resistance of the patient to take oral medicines, such as terbinafine or fluconazole, she was admitted to the Hospital das Clínicas to initiate a treatment with systemic amphotericin B. Additionally, it is important to observe that all these side effects were associated with the therapy with potassium iodide or itraconazole since the patient had no underlying diseases. Electrolytes, renal, and hepatic biochemical tests as well as electrocardiogram were performed, before beginning treatment. Amphotericin B deoxycholate at 50 mg/day (diluted in 500 mL of sodium chloride 0.9% and glucose 5% solution for 6 hours) was given during three days due to the inaccessibility of the liposomal formulation. At the beginning of treatment, episodes of nausea and vomiting were reported, but antiemetic medicines controlled these side effects. Biochemical tests were performed and revealed an increase of serum potassium and creatinine. Correction of electrolyte disturbance was carried out; and to compensate the biochemical alterations, the treatment was suspended for three days. A second set of treatment was performed with liposomal amphotericin B seven days after the infusion with amphotericin B deoxycholate, and it was administered at 150 mg/day (diluted in 500 mL of sodium chloride 0.9% and glucose 5% solution for 6 hours) during 17 days. Clinical improvement of the lesions was observed during treatment (Figures
