Polymorphous light eruption (PMLE) is an acquired disease and is the most common of the idiopathic photodermatoses. In dermatology, a number of other conditions as a response to sunlight exposure have also been reported, however, there is no study detailing the dermatological co-morbidity profile of clinically diagnosed PMLE cases.
Aims and Objective: To study dermal co-morbidity profile of PMLE cases.
Materials and Methods: Hundred PMLE patients were studied at Department of Dermatology, Venereology & Leprosy, Era’s Lucknow Medical College and Hospital, Lucknow during a period of one year for demographic, clinical and histopathological findings.
Results: Maximum patients had age <30 years (54%) with female preponderance (58%). Maximum patients had an acute onset (61%) mainly in summer season (78%). A total of 77 patients had dermal co-morbidities. Melasma was the most common co-morbidity (23%). Histopathology was performed in 89 cases and confirmed PMLE in only 56.92% cases. Presence of dermal co-morbidities in a large number of cases (77%) and lack of confirmed diagnosis in almost half the cases stress on the need to adopt a comprehensive clinical and histopathological evaluation approach.
Conclusion: PMLE was characterized by a higher prevalence of other dermal conditions, thus indicating the vulnerability of these patients to other skin disorders.
