Dermatoscopic Evaluation of Facial Melasma
Abstract: Background: Dermatoscopy is a non - invasive diagnostic tool for pigmented lesionsMelasma is a common problem encountered in dermatology clinics [1]. It helps in visualizing subtle clinical patterns of skin lesions and subsurface skin structures not normally visible to unaided eye. Aims & Objectives: 1) To evaluate dermatoscopic findings in facial melasma. 2) To determine correlation between clinical and dermatoscopic features of various facial Melasma. 3) To correlate dermatoscopic features with histopathological findings in facial Melasma wherever possible. 4) To correlate the treatment response. Results: The present study is to evaluate dermatoscopic findings in facial melasma. The age of these patients was 21 - 62 years, most patients belonging to the age group 31 - 40 years. Mean age group was 37.59 (+/ - 7.28232). Female patients (42) are more commonly affected (80%). Maximum number of patients were housewives (57%).15% were manual labourers. History of sun exposure was predominantly seen in 46 % cases. Out of 50 patients of melasma studied, clinically 19 (38%) patients presented commonly with mixed type, 12 (24%) patients with malar, 10 (18%) patients are centrofacial type and 9 (18%) patients with mandibular type. Out of 50 patients in our study, 50% patient have mixed type of colour changes on dermatoscopy then reflecting 30% showed dermal type of colour changes and 20% showed epidermal type colour changes. That is, 58% cases showed light brown background on dermatoscopy, 20% cases showed ash grey background and 22 % cases showed dark brown background. Out of 50 patients studied 24 patients (48%) have accentuated pigment network is the most common finding, 12 patients (24%) with reticuloglobular pattern, 6 patients (12%) have annular pattern, 2 patients (4%) have blotchy pigmentation, 3 patients (6%) have arcuate pattern, 3 (6%) patients were unpatterned. The persistent type of melasma was (60%) in 30 patients and transient type was (40%) in 20 patients. Conclusion: Thus, dermatoscope is an innovative instrument playing a vital role in diagnosing various conditions especially facial melanosis that have overlapping clinical entities and where histopathology on face is not feasible.
