【 摘 要 】

Pruritic folliculitis of pregnancy is a noninfective dermatosis of the gestation period characterized by multiple pruritic follicular papules and/or pustules which is not uncommonly mistaken for other similar skin disorders that may occur during pregnancy. In the present article we describe the usefulness of dermoscopy as a supportive diagnostic tool in a case of pruritic folliculitis of pregnancy. The main (always present) dermoscopic clue consisted of a vellus hair in the centre of each papule/pustule. Moreover, most papules showed a central yellowish-orange hue with some dotted vessels and irregular haemorrhagic spots. The detection of the aforementioned dermoscopic features might help distinguish pruritic folliculitis of pregnancy from its main differential diagnoses, mainly including microbial folliculitis, prurigo lesions, and the papular stage of pruritic urticarial papules and plaques of pregnancy, as they typically show different dermoscopic patterns.
