This study was undertaken to characterize dermoscopic features of TSDF and to correlate them with potency and duration of application of the TCS.
Methods: The present study was conducted in the department of skin. Sample size of 100 cases was included in the study. Patients (18 years or above) with clinical symptoms and signs suggestive of TSDF (redness, itching, acne, burning, swelling, photosensitivity, pigmentation and atrophy) and with history of application of TCS on the face for a period of more than one month were included in the study after obtaining written informed consent.
Results: In the present study, Females (80, 80%) constituted the majority as compared to males. Most of the patients belonged to the age group of 18–30 years (50, 50%) with a mean age of 32.8 ± 8.2 years. Seventy Five (75%) patients had received some form of formal education, while 25 (25%) patients were illiterate. Presenting complaints of the patients were redness in 80 (80%), itching in 70 (70%), pigmentation in 60 (60%), burning in 64 (64%) and acne in 35 (35%) patients. Duration of TCS application ranged from one month to 25 years with 50 (50%) patients having applied TCS for over one year.
Conclusion: Dermoscopy in TSDF can help dermatologists in a multitude of ways from confirming the diagnosis to differentiating from other causes of red face and predicting the approximate duration of TCS abuse

A lymphangioma (or lymphatic malformation) is congenital proliferation of lymphatic vessels accounting for approximately 4 percent of vascular tumors and 25 percent of benign vascular tumors in children.¹ One of the predominant types is lymphangioma circumscriptum consisting of multiple, grouped vesicles that may be pink, red, or black, owing to serosanguinous fluid or hemorrhage. These contain lymph fluid and are often said to resemble frogspawn. We present a case of lymphangioma circumscriptum on the right inguinal fold in a 15-year-old girl who was diagnosed clinically based on dermoscopy and histopathology and subsequently treated with sclerotherapy followed by radio frequency ablation.

Background: Hair loss is a frequent complaint, diseases that result in hair loss lead to low self-esteem and impaired psychosocial interactions. Present study was aimed to study trichoscopic relevance in the differential diagnosis of alopecia in tertiary care center.
Material and Methods: Present study was single-center, a cross‑sectional observational study, conducted in patients attending dermatology OPD, with complaint of hair loss.
Results: In present study, 228 patients of alopecia were studied. Majority were from 21-30 years age group (29.82 %) followed by > 41 years age (25.88 %) & 31-40 years age (21.49 %). Male patients (65.35 %) were more than female (34.65 %).  Among patients of Androgenetic alopecia (male) (66 cases), common trichoscopic findings were yellow dots (100.00 %), diameter diversity>20% (96.97 %), thin hair (93.94 %), vellus hair (54.55 %) & honeycomb pigment network (25.76 %).  In patients of female pattern hair loss (41 cases), common trichoscopic findings were diameter diversity>20% (85.37 %), thin hair (73.17 %), yellow dots (39.02 %), vellus hair (26.83 %) & honeycomb pigment network (14.63 %). Among patients of alopecia areata (52 cases), common trichoscopic findings were yellow dots (88.46 %), black dots (82.69 %), exclamation mark hair (65.38 %), vellus hair 53.85 %) & thin hair (42.31 %). In patients of telogen effluvium (45 cases), common trichoscopic findings were thin hair (77.78 %) & yellow dots (44.44 %).
Conclusion: Along with clinical and histopathological findings, trichoscopy is valuable, noninvasive, useful, low‑cost technique & relevant investigation in the differential diagnosis of alopecia.

Background: Dermoscopy can act as an alternative diagnostic method to mucosal biopsy for diagnosis of various oral mucosal lesions.
Aim: To study the dermoscopic and histopathological characteristics of oral mucosal lesions.
Methods: The present prospective study was conducted among 53 patients of oral mucosal lesions presenting to the indoor and outdoor facilities in Department of Dermatology, Venereology and Leprosy. After performing routine investigations, dermoscopic evaluation was done in all the cases and recorded in the prestructured proforma. Oral mucosal lesions were evaluated by using non-contact videodermatoscope (AM7515MZT Dino-Lite), polarised mode. It was followed by mucosal biopsy from the same site.
Results: Nonvascular findings were the predominant features on dermoscopy. Structureless grey areas was the most common finding, seen in 72.41% patients of lichen planus. In lichen planus, it is suggested that structureless grey areas on dermoscopy corresponded histologically to hyperkeratosis. Vascular findings in form of light to intense red areas was seen in all patients of pemphigus vulgaris as well as both cases of aphthous ulcer and in each case of actinic cheilitis, bullous pemphigoid, disseminated discoid lupus erythematosus.
Conclusion: Theresultsof this rare pioneer study revealed that dermoscopy of mucosa may prove to be a valuable tool for diagnosis and may obviate need for mucosal biopsy.
