Abstract


Objective To determine the association of periorbital melanosis with pigmentary demarcation line-F.

 

Methods This observational study was carried out at the Department of Dermatology, Services Institute of Medical Sciences/ Services Hospital Lahore, from January 2017 to June 2017. A total of 50 patients of periorbital melanosis of any age and either sex were included. The association between periorbital melanosis (POM) and pigmentary demarcation line-F (PDL-F), if present, was determined by close inspection of the patients, histopathological and Wood’s lamp examination.

 

Results In 44 (88%) patients, PDL-F was observed along with POM. Histopathological examination carried out on 5 patients showed melanin pigment within dermal macrophages in both POM and PDL-F. In 9 (18%) patients, both POM and PDL-F became indiscernible on Wood’s lamp examination.

 

Conclusion POM and PDL-F are common chronic and same pigmentary conditions and should be considered as a single entity.
