BACKGROUND
Lichen planus pigmentosus inversus (LPPI) is a rare variant of LP. Only 31 cases have been reported in the literature.

METHODS
Here we report a series of 10 patients with LPPI from North Africa.

RESULTS
Ten cases of LPPI, clinically suspected and histologically confirmed, were seen over 3 years (2013-2015). The mean age of patients was 62.4 years old. Eight patients were women and two were men. Main folds involved were the axillae and groin. All patients were treated by topical steroids without success.

CONCLUSIONS
Our series of LPPI seems that this disorder is underreported mainly among 3 dark-skinned persons as we have seen these ten cases within three years.
