der·ma·to·phi·lo·sis (dur″mə-to-fĭ-loґsis) infection with Dermatophilus congolensis, seen in many different mammals. In humans it is characterized by nonpainful pustules on the hands and arms that later break down, forming shallow red ulcers that heal to leave scars. The sheep condition (also called lumpy wool, proliferative dermatitis, or strawberry foot rot) is characterized by exudative, red, scaling lesions that form pyramidal masses.Medical dictionary. 2011.
