ABSTRACT

Pigmented lesions on the vulva are rare and their non specific features cause difficulties in their diagnosis and differential diagnosis. Because of their localization, it is difficult to follow up vulvar lesions, which are generally noticed coincidentally by patients. Vulvar pigmented lesions are classified clinically as macules/papules and patches/plaques to provide ease of the diagnosis.

Nevi, angiokeratomas, seborrheic keratosis, melanoma, basal cell carcinoma and squamous cell carcinoma are classified under the macules/papules, and post-inflammatory hyperpigmentation, physiological hyperpigmentation, melanosis and acanthosis nigricans are classified under the patch/plaque. Dermatoscopic examination, which is increasing recently, is very valuable for avoiding possible cosmetic and functional complications of surgical procedures. However, epidermal pigmentations such as vulvar melanosis and vulvar intraepitelyal neoplazi are dermatoscopically indistinguishable. It may also be difficult to diagnose vulvar melanoma clinically and dermatoscopically. Histological examination is the gold standard for the diagnosis of pigmented vulvar lesions, which are clinically and dermatoscopically indistinguishable. (Turk J Dermatol 2012; 6: 39-44)
