title: Pilomatricoma of the male breast: sonographic mammographic MRI features with pathologic correlation.
abstract: We report a case of 43-year-old man who presented with an enlarging, painless, palpable mass in the left breast for one year associated with surface blue discoloration of the skin. Mammogram showed a well-defined 2.3-cm mass with microcalcifications. Ultrasound revealed a well-defined, subcutaneous hypoechoic mass adherent to the skin with multiple bright foci. Ultrasound-guided needle biopsy produced a dark-colored sample corresponding to pilomatricoma on final pathology. Bilateral breast magnetic resonance imaging showed heterogeneously hyperintense in T1- and T2-weighted images with heterogeneous enhancement toward the delayed phase. Surgical resection was carried out with wide margins.
