A rare, chronic, photodermatosis disease characterized by intensely pruritic, polymorphic, erythematous, excoriated and/or lichenified papules, macules, plaques and nodules, occurring on sun-exposed areas of the skin (particularly face, nose, lips, and ears), frequently associating cheilitis (especially of the lower lip) and conjuctivitis, which are present year-round or only in the spring/summer (depending on geographic location), observed mainly in Native Americans and Mestizos. Cheilitis may be the sole clinical presentation. Histologically, the presence of lymphoid follicles in mucosa is pathognomonic.
