ABSTRACTBackground: lichen ruber planus is a chronic idiopathic inflammatory disease, which affects skin, mucous membranes and nails. It affects general population in 0.14 to 0.8% and is more common in women aged 30-60 years. The most frequent clinical presentations are ruber or classic, pigmented, atrophic, hypertrophic and oral.
Objective: to describe clinical and epidemiological characteristics of patients with lichen planus in the Dermatology Center of Yucatan.
Material and method: descriptive, transversal, retrospective study from January 2006 to December 2014 at Dermatology Center of Yucatan “Dr. Fernando Latapí”, including data of patients with histopathological diagnosis of any clinical variety of lichen planus.
Results: we included 129 cases, 66% were female, and 34% male. The mean age was 41 years. The most common clinical variety was classic lichen planus in 63 cases (49%), affecting mainly lower extremities (23%), upper extremities (20.35%) and head (14.16%); association with hepatitis B (0.77%) was observed in one case, and another one with hepatitis C (0.77%). We found 16 pediatric cases with 10-year-old average age and the most frequent clinical variety was classic lichen planus (43.75%). The most frequent location was lower extremities (43.75%), with a mean evolution of eight months.
Conclusions: in this study lichen ruber planus affected more women with an average age of 41 years, affecting mainly limbs and head. Clinical features in pediatric patients are similar as adults.
