Basal cell carcinoma with matrical differentiation: a case study with analysis of beta-catenin

J Cutan Pathol. 2005 Mar;32(3):245-50. doi: 10.1111/j.0303-6987.2005.00301.x.

Abstract

Matrical differentiation in basal cell carcinoma (BCC) is rare. Only nine cases have been described that showed typical diagnostic features of BCC, in addition to shadow cells indicating hair-matrix differentiation. These cases often present a diagnostic challenge due to confusion with pilomatrixoma or pilomatrix carcinoma. We present a case of BCC with matrical differentiation in a 78-year-old man. Immunohistochemical and molecular methods are used to differentiate this lesion from benign or malignant forms of pilomatrixoma. differentiation: a case study with analysis of beta-catenin.
