lichen striatus must be differentiated from systematized eruptions such as lichen planus ( the simultaneous occurrence of l.s . and lichen planus is extremely rare and the resemblance of one dermatosis to the other can be so pronounced that a differential diagnosis is difficult ) linear localized neurodermatitis , linear psoriasis ( almost always associated with more typical lesions of psoriasis elsewhere on the body ) , linear keratosis follicularis ( histologically typical of darier 's disease ) and linear epidermal nevus which occasionaly does not appear at birth but later in life and may present nail involvement .
