To the Editor.—
One of the distressing conditions of actinic reticuloid (AR) is its persistence for long durations without any demonstrable contact with the photoallergen. It is hypothesized that autoreactive cells are activated in the skin lesion of AR.1 We report a case of AR with the immunohistochemical study of the affected site.
