href="#fig0005">Figs. 1 and 2</a>). No other anatomical area was involved. Under Wood’s light the lesions appeared bright white and sharply demarcated, confirming the diagnosis of vitiligo. His personal and family medical history was negative for autoimmune disorders. The patient reported that eight months before, a diagnosis of acquired secondary idiopathic hypogonadism due to aging was made (low levels of testosterone; normal LH and FSH levels; negative MRI of the hypothalamic-pituitary region and normal body mass index). Laboratory investigations and analysis of autoimmunity showed no alterations. Thyroid function was normal and thyroid antibodies were absent. According to this diagnosis, he started treatment with topical testosterone 2% gel once a day for six months, which he applied at level of the chest and thighs. He noticed the first depigmentation area on the hands, during the fourth month of treatment. For vitiligo areas, pimecrolimus 1% cream was prescribed. After six months of follow-up, the treated vitiligo areas are stable and no further depigmented areas arose. The patient continues to perform the endocrinological consultations with good hormonal compensation.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><elsevierMultimedia ident="fig0010"></elsevierMultimedia><p id="par0010" class="elsevierStylePara elsevierViewall">The etiology of vitiligo is still unclear.<a class="elsevierStyleCrossRef" href="#bib0005"><span class="elsevierStyleSup">1</span></a> Several hypotheses have been proposed to explain the causes of melanocyte dysfunction.<a class="elsevierStyleCrossRef" href="#bib0005"><span class="elsevierStyleSup">1</span></a> In this regard, Kotb et al. also investigated the hormonal theory.<a class="elsevierStyleCrossRef" href="#bib0005"><span class="elsevierStyleSup">1</span></a> Specifically, they found a significant decrease in testosterone levels in the serum of males in both active and stable vitiligo groups when compared to controls, and in the active vitiligo group compared to the stable vitiligo group; besides, they did not find significant difference in testosterone levels between males and females in the active vitiligo group.<a class="elsevierStyleCrossRef" href="#bib0005"><span class="elsevierStyleSup">1</span></a> Furthermore, testosterone can be also involved in the downregulation of the inflammation.

Indeed, no areas of depigmentation were observed at the testosterone application sites (chest and thighs).
