Discussion

CS is an autosomal dominant genodermatosis, with PTEN variations occurring in 35% of patients. It is characterized by the presence of cutaneous lesions and systemic neoplasms, either benign or malignant, such as thyroid carcinoma, breast carcinoma, colonic hamartomatous polyposis, kidney carcinoma, and dysplastic gangliocytoma of the cerebellum (Lhermitte-Duclos disease), among others. Cutaneous lesions related to CS include trichilemmomas, acral keratosis and acral pits, mucocutaneous neuromas, oral papillomas, and sclerotic fibromas. 1, 2 Dermoscopic features of sclerotic fibromas were first reported in 2018 by Ebadian et al. 3 They described the presence of a white background with peripheral arborizing vessels. 3 This dermoscopic pattern can also be seen in atypical dermatofibromas, late stages of sclerotic dermatofibromas, and amelanotic blue nevi. 3, 4
