Clinical and Dermoscopic Features of Vulvar Melanosis Over the Last 20 Years.

Importance: Vulvar melanosis is a common pigmentary change that accounts for most pigmented vulvar lesions. It presents as single or multiple asymptomatic macules or patches of varying size and color that may be asymmetric with poorly defined borders. The differential diagnosis of melanocytic lesions includes melanoma, which creates anxiety for patients and the physicians who diagnose the condition and treat the patients.

Appearance of cutaneous melanoma and subcutaneous metastases in metastatic gastric carcinoma undergoing chemotherapy with oral 5-fluorouracil prodrug.

Metastatic skin lesions of gastric cancers usually appear as nonspecific, firm, and hyperpigmented nodules. However, they occasionally present as unusual skin manifestations that mimic other skin disorders. We describe a case of multiple cutaneous metastases from gastric cancer resembling sebaceous cysts with a synchronous melanoma, in a patient after fluoropyrimidine-based systemic chemotherapy.

Nevi and Breslow thickness in melanoma: sex differences?

A large body of evidence in the scientific literature suggests that the numbers of common and atypical nevi are strong, independent risk factors for the occurrence of cutaneous malignant melanoma. Furthermore, some studies recently found an association between high nevus counts and an improved melanoma prognosis. The aim of this study was to investigate a possible relationship between the number of common and atypical nevi and melanoma prognostic factors.

Fluorescence-advanced videodermatoscopy: A promising and potential technique for the in vivo evaluation of vitiligo.

Fluorescence advanced videodermatoscopy (FAV) has been proposed recently to be a new, noninvasive method for in vivo skin examination at high magnification. The working principle underlying FAV relates to the ability of endogenous molecules to absorb specific wavelengths and emit fluorescence. Herein we report our experience with FAV in the study of active, non-segmental vitiligo treated with narrowband UVB.
