Abstract

Partial unilateral lentiginosis is a rare pigmentary disorder which is characterized by multiple grouped lentigines in unilateral or segmental distributions. The ocular involvement of the disease is extremely rare and only four cases have been reported until today. The exact pathophysiology is still unknown. An 18-year-old woman is being presented with unilateral hyperpigmented macules on her left forehead, eyelid, cheek, lip and chin which all demarcated sharply at the midline of her face. The lesion has been presented since the age of 1. Also, there are discrete brownish pigmentations on her left bulbar conjunctiva. Biopsy specimen is being obtained from the left chin and the histopathological examinations revealed increasing basal layer of pigmentations and mild elongation of rete ridges. The histopathological features are also consistent with lentigo simplex. Herein, we present a rare case of partial unilateral lentiginosis with an ocular involvement. We have also proposed that the partial unilateral lentiginosis has a possibility of ocular involvements.
