BACKGROUNDS Basal cell carcinoma (BCC) is the most common cutaneous neoplasm. Despite numerous previous studies, the origin of BCC is still controversial. OBJECTIVE The aim of this study is to evaluate whether BCC arises from the hair follicle rather than the epidermal basal cell. METHODS The labeling index and differences of expression of the immunohistochemical (IHC) stainings of CK15, CK19, follistatin, and Bmi-1 were evaluated in 20 cases of BCC, 13 cases of trichoblastoma, 21 cases of… CONTINUE READING
