BCCs have a characteristic related to the difficulty they present with differentiation from trichoblastoma, so there are two novel biomarker candidates: Meteorine-Like Peptide (METRNL) and Asprosin, where METRNL presented an overexpression in the lesion area of the trichoblastoma, but Asprosin did not increase, but in BCC samples, they both are relatively higher [115]. The gene discussed is METRNL; the disease is trichoblastoma.
