Afecta principalmente a mujeres mayores de cincuenta años, se localiza por lo general en zonas fotoexpuestas, suele ser asintomático y de rápido crecimiento, presenta un elevado porcentaje de recurrencias y metástasis, siendo el lugar más frecuente de diseminación la piel, seguido por los ganglios regionales.
