[Actinic reticuloid and pigmented exuberant conjunctivitis. Report of case].

The authors report the case of a patient showing simultaneously actinic reticuloid (AR) and pigmented exuberant conjunctivitis (PEC), which are frequently encountered separately in the highlands of Bolivia. This pathological association could be in favour of the actinic origin of PEC, whereas for RA this origin is quite obvious. The main characteristics of PEC are described, insisting on differentiation with spring conjunctivitis. As a consequence of this association and the observation of other similar cases of PEC in the course of other photodermatoses, the authors are led to consider PEC as the only extra-cutaneous alteration up to now, and one more feature in the clinical picture of photodermatoses of altitude.
