Rosettes (also known as ‘four-clod dots’) are defined as four white points, arranged as a four leaf clover. They are not lesion-specific and are described in many tumoral and inflammatory lesions, including: scars, dermatofibroma, actinic keratosis, squamous cell carcinoma and melanoma and more. Smaller rosettes are mainly caused by polarizing horny material at infundibular level in adnexal openings and larger rosettes mainly by concentric perifollicular fibrosis [1].
