Histologically, BCC is divided into the following 2 categories:

  • Undifferentiated: 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 histologic subtype)

  • Differentiated: Differentiated BCC often has slight differentiation toward hair (keratotic BCC), sebaceous glands (BCC with sebaceous differentiation), and tubular glands (adenoid BCC); noduloulcerative (nodular) BCC is usually differentiated
