ABSTRACT
Nineteen patients with lichen striatus were investigated by clinical data, clinical photographs and histopathologic study by the pattern analysis method of Ackermsn. Results were as follows '. 1. The male to female ratio was 1: 1.1, and average age was 7.8 years. Seven- teen patients (about 90%) visited hospitals during summer season. 2. Nine cases showed superficial perivascular dermatitis, 9 cases interface dermatitis (vacuolar type : 7, lichenoid type, 2), 1 case nodular dermatitis and 2 rases interface dermatitis with nodular dermatitis. 3. In the epidermis, 9 cases showed variable nurnber of dyskeratotic cells. One case showed finding of perforating lichen striatus. 4. Two cases showed inflammation around acrosyringium, 4 cases around hair follicle, 6 cases around eccrine sweat gland and 1 case showed perineural inflamrnation. Summarizing above results, histopathology of lichen striatus characteristically shows superficial perivascular dermatitis, interface dermatitis, and infiltration of inflammatory cells around the sweat gland, which helps to diagnose the disease.
