Histopathology and immunohistochemistry of dermatofibrosarcoma protuberans (DFSP) mass on the posterior scalp. (A) Hematoxylin-and-eosin-stained images of DFSP showed spindle cell tumor in storiform pattern (200×). (B) Hematoxylin-and-eosin-stained images of DFSP showed spindle-shaped cells, arranged in intersecting fascicles that resembled a herring bone appearance (400×). (C) Immunostaining profiling displayed strong CD34 expression in the storiform area (200×).
