White rosettes in borderline lepromatous leprosy: A new observation

: Dermoscopy is a non-invasive diagnostic tool which aids in visualizing morphology of the skin. Recently, the focus of dermoscopy is extended to the inflammatory and infectious conditions. Dermoscopy demonstrates characteristic patterns in respect with pigment network, background color, type of scales, vascular arrangement and follicular structures in a given skin lesion. 1 Follicular structures are observed as white specks, brown to gray globules and red dots that represent follicular plugs, perifollicular pigmentation and erythema. Yellow and white dots which correspond to dilated follicle with sebum and empty follicles are other dermoscopic features of follicles. 2 White rosettes are special structural change of follicles in dermoscopy and they suggest hyperkeratosis of dilated infundibulum. White rosettes are seen in many conditions including basal cell carcinoma, dermatofibroma, nevus, squamous cell carcinoma, melanoma, lichen planopilaris and molluscum contagiosum. 3 We herewith, document a case of borderline lepromatous (BL) leprosy demonstrating white rosettes in the facial lesions.
