Abstract

The dermatologic conditions affecting the male genitalia are diverse and range from normal variants and benign growths to overt malignancy. Unfortunately, there is a dearth of urologic dermatology training in most residency programs, and many dermatologic lesions with a classic appearance on other areas of the body may have atypical presentations on the genitalia. Patients may present to a variety of physicians without receiving a definitive diagnosis, which can be highly distressing to the afflicted individual. To provide sexual medicine physicians tools to aid in the evaluation and diagnosis of urologic dermatology lesions, whether they are limited to the genitalia or part of a widespread systemic disease. Comprehensive review of the literature pertaining to genital dermatology in men. We stratify each condition into 1 of 5 groups (normal variants and benign lesions, inflammatory lesions, transmissible lesions, premalignant lesions, and malignant lesions) and focus on presentation and prevalence of these conditions. Sexual medicine physicians should emphasize the non-pathologic nature of normal variants of genital anatomy (ie, penile hyperpigmentation, pearly penile papules) and stress that removal of these lesions is only appropriate for cosmetic purposes. Benign genital growths (ie, sebaceous cysts, seborrheic keratoses) may not require intervention, but they should be monitored for atypical features and infection. In contrast, transmissible (ie, herpes, syphilis) and inflammatory (ie, psoriasis) lesions may necessitate prompt intervention to reduce transmission and complications of late-stage disease. Premalignant and malignant lesions may mimic many of the aforementioned conditions; it is important that patients receive routine follow-up after treatment. All suspicious non-healing or ulcerating lesions should undergo pathologic evaluation to rule out malignancy. Urologic dermatology can be a diagnostic challenge for sexual medicine physicians. This review simplifies the diagnostic approach and emphasizes pathologic features of each condition to guide management. Gabrielson AT, Le TV, Fontenot C, etal.
