摘要

Background. Dermoscopy provides additional criteria for the diagnosis of nonpigmented skin lesions.Case Report. An 80-year-old woman presented with an isolated, firm, dome-shaped, erythematous nodule with surface telangiectasia on her forehead. Dermoscopy showed areas of background pink coloration with arborizing telangiectasia, blue dots/globules, and ulceration. Histologic analysis revealed features of cylindroma.Conclusion. Our case suggests that cylindromas may be added to the list of adnexal tumors mimicking BCC.
