How is histology of basal cell carcinoma?

• Undifferentiated BCC: when there is little or no differentiation, the carcinoma is referred to as solid BCC; this form includes pigmented BCC, superficial BCC, sclerosing BCC, and infiltrative BCC (a histologicsubtype) • Differentiated BCC: often has slight differentiation toward hair (keratotic BCC), sebaceous glands (BCC with sebaceous differentiation), and tubular glands (adenoid BCC); nodulo-ulcerative (nodular) BCC is usually differentiated
