Objective. This study describes the clinicopathologic features and therapeutic results of 116 patients with actinic prurigo cheilitis seen over an 11-year period. Study Design. A retrospective study was carried out with hospital records and a microscopic slide review from a large dermatology department in Mexico City, Mexico. Results. The study consisted of 42 male (36.2%) and 74 female (63.8%) patients, with a male to female ratio of 1:1.7. Age ranged from 9 to 82 years (mean, 27.9 years; standard deviation, 14.2). Thirty-two cases (27.6%) were found in which cheilitis was the only manifestation of this condition. Pruritus, tingling, and pain of the vermilion were recorded in 96 cases (82.7%). Typical histopathologic findings included in most cases the presence of acanthosis, spongiosis, basal cell vacuolation, ulceration with serohematic crust formation, edema of the lamina propria, lymphocytic inflammatory infiltrate with well-defined lymphoid follicles, and variable numbers of eosinophils and melanophages. Improvement of the symptoms was obtained in 112 cases (96.5%) with sun-protective measures and diverse antiinflammatory agents. However, complete resolution of the labial lesions were more frequently achieved with the combination of topical steroids, thalidomide, and sun-protective measures (42.2%) as compared with topical steroid therapy plus sun-protection measures (16.3%; P <.005). Conclusion. Our findings confirm that lip lesions may appear as the only manifestations of this photodermatosis and that it has typical clinical and microscopic features and should therefore be considered a specific form of cheilitis.
