Aim: This study was undertaken to better understand clinical characteristics, environmental and physical events in Down syndrome (DS) and alopecia areata (AA). Material and Methods: Cross-sectional study was performed with 18 individuals with DS who were currently presenting or had presented AA. Were evaluated: gender, age, local and type of AA, presence of autoimmune disease or atopy, AA in first-degree relatives, environmental, physical and clinical intercurrences. Results: Average age was 11.6 years (y) (SD ± 5.5y) and average age of AA onset was 7.2y (2.5 to 15.2y). The duration of alopecia episodes varied; an average of 2.7y (0.1 to 18.7y) was observed. Recurrence of AA was reported in 27.7% (5/18) and the average number of recurrences was 3.6. Localized type, was seen in 83.4% of individuals, and the most frequent location was scalp (100%). Seven of the individuals presented atopy. Fourteen of the individuals had undergone environmental and/or clinical intercurrences. Conclusion: The most frequent presentation of AA in DS is the non-recurrent, localized form, on scalp, with varied period of duration. Changes in individuals’ routine, occurred in more than half of the studied group. We suggest further studies of the psychology and immunogenetics of the etiopathology of AA in DS.
