Sweat dermatitis is a peculiar kind of irritant inflammatory dermatoses occurring due to prolonged exposure of retained sweat over the skin. It is commonly seen in hot and dry climates like tropics during summer months due to thermal stress. Typically, parchment paper or cellophane paper like scaling is seen over occluded areas of back, shoulder, and other areas. Here we have reported a varied presentation of sweat dermatitis in the form of its coexistence with miliaria rubra (impending to thermal burn). Further we have also observed co existing pityriasis versicolor and sweat dermatitis where the former has prevented the development of latter. Till date there is very little discussion on this condition, so we have tried to provide a concise review about sweat dermatitis along with its classical to atypical presentation with special emphasis on dermoscopy.

Striae distansae (SD) or stretch marks are very common, asymptomatic, skin condition frequently seen among females between 5 to 50 years of ages. It often causes cosmetic morbidity and psychological distress, particularly in women and in certain professions where physical appearances have significant importance. Of late, with the increasing emphasis on cosmetic management and awareness, patients approach dermatologists for stretch marks treatment. However, despite several advances, no fully effective treatment has emerged. Unfortunately, there is paucity of the strong evidence in the literature for the effective treatment of striae. A literature search using the terms 'striae distansae (SD or stretch marks' was carried out in the PubMed, Google Scholar and Medline databases. Only articles related to the treatment were considered and analysed for their data. Commonly cited treatments include topical treatments like tretinoin, glycolic acid, ascorbic acid and various lasers including (like) carbon dioxide, Er:YAG, diode, Q-switched Nd:YAG, pulse dye and excimer laser. Other devices like radiofrequency, phototherapy and therapies like platelet rich plasma, chemical peeling, microdermabrasion, needling, carboxytherapy and galvanopuncture have also been used with variable success. This article reviews all currently accepted modalities and their effectiveness in the treatment of stretch marks. [ABSTRACT FROM AUTHOR]

Ophthalmic medications used for diagnostic or therapeutic purposes are common causes of allergic contact dermatitis around the eyes. We report a case of periocular allergic contact dermatitis due to tropicamide and phenylephrine eye drops in a 1‐year‐old infant. [ABSTRACT FROM AUTHOR]

Hair casts (HCs) are thin, elongated, firm, whitish cylindrical concretions which ensheath the hair shaft and can be easily dislodge. They are of two different types: peripilar and parakeratotic keratin cast. Due to its clinical resemblance to pediculosis capitis, the entity is also known as pseudonits. Al though not unusual, false diagnoses are common, and thus, it is very important to correctly differentiate it from other similar conditions. We report here a case of HC involving scalp as well as body hair in association with androgenetic alopecia in a 22-year-old male patient. The patient's sister was also affected with pseudonits.
