Overview
Dermatofibroma may be classified according to histopathology into three groups, variants that are prominent in architectural (low-power) properties, variants that are prominent in cytologic or stromal (high-power) properties, and variants that have architectural (low) and cytological or stromal (high-power) properties.
Classification
Dermatofibroma may be classified according to histopathology into three groups:[1][2][3][4][5][6][7][8][9]
- Variants that are prominent in architectural (low-power) properties
- Variants that are prominent in cytologic or stromal (high-power) properties
- Variants that have architectural (low) and cytological or stromal (high-power) properties
