“…This can be explained by UV radiation directly inducing the increase of melanogenic activity, thereby causing the development of epidermal pigmentation and occurs more intensely in regions with melasma than in the adjacent skin. 22,23 A 2013 study conducted in Brazil on the epidemiological characteristics of facial melasma identified the predominance of centro-facial melasma (51.7%), followed by mixed melasma (43.4%).…”

Background: To study the spectrum of periorbital dermatoses in patients of both genders irrespective of age and identify any underlying etiology.Methods: A clinico-epidemiological study of periorbital dermatoses was done in all patients with skin lesions in and around the both eyes who visited our outpatient department. Digital photographs will be taken for all the patients with periorbital dermatosis. Data obtained was compiled, tabulated, and statistically summarized using SPSS version 16.Results: Among 110 patients, majority of patients with periorbital dermatoses, were in the age group of >50 years (40%) including 77 (70%) females and 33 (30%) males. The most common dermatoses observed in periorbital region were benign and malignant skin tumors 46 (41.8%), followed by pigmentary disorders 21 (19.1%), miscellaneous 19 (17.3%), nevoid conditions 12 (10.9%), eczema 6 (5.5%), and infections 6 (5.5%).Conclusions: Benign skin tumors and pigmentary disorders are the most common periorbital dermatoses seen in our study. Certain periorbital dermatoses like skin tag and xanthelesma are seen associated with underlying metabolic disorders.

“…8 The centrofacial pattern in 55% -75%, the malar pattern in 24% -43%, and the mandibular pattern in 1.5% -2% patients are three distinct clinical patterns. 10,11 Its exact etiology is poorly understood but often imputed to genetic predisposition, pregnancy and oral contraceptives, endocrinopathies, or drugs (hormones, anticonvulsants, phenothiazines, phototoxic agents) ingestion. 3,4 Pigmented cosmetic contact dermatitis is another recognized etiologic factor.…”

Background: Facial hypermelanosis is a significant cause of cosmetic disfigurement, social embarrassment and psychological morbidity affecting quality of life.Objective: To study clinicoepidemlogic patterns of facial hypermelanoses among men. Material and Methods:Medical records of all adult males presenting with facial hypermelanoses were analyzed for this retrospective cross sectional study for demographic details, duration, cosmetic usage, sun exposure, drug intake, infections, systemic or cutaneous diseases, and family history of hypermelanotic dermatosis. Laboratory investigations and skin biopsy were performed when deemed necessary.Results: These were 300 Indian men aged 18 to 74 (mean 37.35) years with 121 (40.3%) individuals aged 31-50 years. Various patterns of melasma in 230 (76.7%) patients were the major cause of facial hypermelanosis. Periorbital hypermelanosis was observed in 32 (10.7%), freckles and lentigens in 26 (8.7%), acanthosis nigricans in 12 (4%) and lichen planus pigmentosus in 10 (3.3%), pigmented cosmetic contact dermatitis in 7, and nevus of Ota in 6 persons. The 71 (30.8%) patients with melasma had a history of frequent sun exposure, 9 (3.9%) patients had systemic comorbidities. Family history of periorbital melanosis was present in 7 (21.8%), personal or family history of atopy in 5 (15.6%) patients. Acanthosis nigricans was associated with obesity in 9 (75%) of patients and with diabetes mellitus in 4 (33.3%) cases.Conclusions: Melasma, periorbital hypermelanosis, acanthosis nigricans and lichen planus pigmentosus remain the predominant causes for facial hypermelanosis in men.
