چکیده
Objective: To compare the characteristics of Blaschkoian lichen planus with typical lichen planus. Patients and methods In this case series, we diagnosed 7 patients of Blaschkoian lichen planus (3 males and 4 females) based on specific clinical presentation, histopathological findings and exclusion of other dermatologic disease mimicking Blaschkoian lichen planus. Results Of 7 patients, 4 (57.1%) had middle to senile age, without involvement of the buccal mucosa, nails and scalp. Involvement of both trunk and lower extremity were seen in one patient. Unilateral lichenoid skin lesion with specific configuration were located on trunk in 6 (85.7%) cases, forehead in 1 (14.3%) and on lower extremity in 1 (14.3%) case. One (14.3%) patient had history of troublesome pruritus. Conclusion Although diagnosis of typical lichen planus is uncomplicated but in Blaschkoian lichen planus absence of prominent pruritus, different configurations of skin lesion on each site of the body without involvement of buccal mucosa may pose problems in diagnosis. We recommend further studies with large number of Blaschkoian lichen planus to find out more about clinical manifestations.
