Linear porokeratosis is characterized by linear hyperkeratotic papules and annular plaques arranged along the Blaschko lines.


Here we report a case of linear porokeratosis and describe the dermoscopic features for the first time.

Patients/materials and methods

Dermoscopic and histopathological features of the linear porokeratosis were evaluated.


In this report, we point out "the variation of the dermoscopic findings of linear porokeratosis in relevance to the age of the lesions". And we described new dermoscopic features like "the gray-brown pigment network-like appearance", "the reddish vascular network" in linear porokeratosis.


The findings of this report may help to improve the diagnosis.
