Background:Dermatoscopy is a new noninvasive tool for the diagnosis of various skin and hair disorders. Dermatoscopy of alopecia areata (AA) shows various specific features, which may aid in confirming the diagnosis.Aims:The aim of this study was to determine the various clinical patterns and the dermatoscopic features of AA.Materials and Methods:A total of 75 patients of AA were evaluated with a dermatoscope (magnification ×25 and ×60).Results:The mean age of onset of AA was 23.58 years. Males were more commonly affected. Scalp was most commonly involved. Patchy alopecia was the most common pattern observed. 10 patients showed concomitant nail changes. The dermatoscopic features included yellow dots (YDs) in 43 (57.33%) patients, black dots (BDs) in 63 (84%) cases, broken hairs (BHs) in 28 (37.33%) cases, short vellus hair (SVH) in 51 (68%) patients and tapering hair (TH) in 14 (18.67%) cases.Conclusion:The most common dermatoscopic finding observed was BDs, followed by SVHs, YDs, BH and TH.

Dowling–Degos disease (DDD) is a rare autosomal dominant condition characterized by multiple, small, round pigmented macules usually arranged in reticular pattern, chiefly distributed in axillae and groins. Here we are reporting three atypical cases of DDD in a family. They had hypopigmented macules with typical features of DDD indicating generalized DDD. Histopathology confirmed the diagnosis. We present these three cases to stress the existence of generalized DDD phenotype in the Indian population.

Type 2 lepra reaction or erythema nodosum leprosum (ENL) is an immune complex syndrome that occurs mostly in lepromatous leprosy and sometimes in borderline lepromatous leprosy patients. We present an untreated case of lepromatous leprosy, who presented with type 2 lepra reaction and livedo reticularis. Livedo reticularis, though seen in lucio phenomenon, is not a part of type 2 lepra reaction. The case is being reported for its rarity.

Introduction Periorbital melanosis (POM) is an esthetic facial concern on increasing trend and has a severe emotional impact on patients. We aimed to study the clinical and dermoscopic patterns of periorbital melanosis to aid in the classification and strategize therapy. Methods A cross‐sectional, observational study was conducted on one hundred patients with POM in a tertiary care center in India from January 2020‐March 2020. Dermoscopic assessment of POM was done using video dermatoscope– FotoFinder Medicam 1000s (magnification up to 140x). Results The mean age of participants was 32.8 ± 9 years. It was more prevalent among females (78%). The constitutional type (43%) of POM was the most common followed by shadow‐effect type (32%). The various dermoscopic pigmentary patterns seen were scattered pigmented dots (56%), exaggerated pigment network (31%), globules (30%), and blotches (27%). Dilated veins and telangiectasia were seen in 50% and 32% of subjects, respectively. Exaggerated skin markings were seen in 43% of participants. Scattered pigmented dots were most commonly seen in constitutional, vascular, and shadow types but were significantly associated with vascular type. Exaggerated pigment network was the most frequent pigmentary pattern in post‐inflammatory type of POM. Globules were significantly associated with constitutional as well as shadow type of POM and blotches with shadow type of POM. Conclusions Periorbital melanosis presents as multifactorial entity with constitutional type being the most common. The dermoscopic patterns of POM may provide a clue to the underlying etiology, thereby helping to plan appropriate treatment.
