Literature is limited regarding the medical and cosmetic dermatologic issues pertinent to transgender patients and the reasons why 19 transgender individuals seek care from dermatologists. Clinical management of this population has historically been limited to 20 mental health providers, endocrinologists, and select surgeons with expertise in sex reassignment surgery. The impact of hormonal 21 therapy on transgender skin has been well documented in endocrinology journals, but is underrepresented in dermatology 22 literature. Hormonal therapy leads to drastic skin alterations, impacting sebum production, hair growth, and acne, all of which may 23 become a dermatologic concern for the transgender patient. Dermatologists may also be consulted regarding issues such as 24 permanent hair removal, androgenic alopecia, or scar revision following breast reduction surgery or genital reassignment surgery. 25 The purpose of this review is to provide relevant information for use by all dermatology providers who care for transgender 26 patients or patients undergoing transition.
