2018
Background: Melasma is one of the most common and distressing pigmentary disorders presenting to dermatology clinics. There is paucity of data regarding the aetiological factors and clinical presentation of melasma in men. The present study was taken up to fill this lacuna and to understand the unique aspects of melasma in this group. Methods: Study was conducted in the Department of Dermatology at University teaching hospital from January 2015 to July 2016. A total of 72 male patients with melasma were studied. A detailed history including occupation, onset, duration and evolution of melasma, predisposing factors like sun exposure and genetic factors, were taken followed by general physical examination, cutaneous examination and Woods lamp examination and recorded in a proforma. Laboratory investigations like complete haemogram, hormonal profile, liver function tests were done whenever necessary depending on the presenting condition. Results: The mean age of onset was 31.5 years. The duration of melasma varied from 3 months to 6.5 years. The aetiological factors identified were, sun exposure in 42 patients (58.3%) and family history in 29 (40.3%). Laboratory investigations revealed hepatic disorders in 5 patients(6.9%), increased luteinizing hormone (LH) and low testosterone in 2 (2.8%) and hypothyroidism in 4 patients (5.6%). According to clinical patterns, malar pattern was seen in 65.3% of patients, centro-facial in 31.9% and mandibular in 2.8% of patients. The most common skin type found to be type IV. Conclusion: Melasma was evident in men in their fourth decade of life; malar pattern, type IV skin type were most commonly seen.
