Original article: Platelet-rich plasma with microneedling in androgenetic alopecia along with dermoscopic pre- and post-treatment evaluation

Platelet‐rich plasma has shown beneficial effects in the treatment of androgenic alopecia with its growth factor properties in accelerating the dermal papilla. Dermoscopy is a noninvasive method that allows the in vivo evaluation of microstructures not visible to the naked eye.

Dermoscopy in vitiligo: diagnosis and beyond

Vitiligo is essentially a clinical diagnosis, and dermoscopy may aid in noninvasive confirmation of diagnosis by excluding other clinically simulating hypopigmentary conditions. More importantly, dermoscopy is rapidly gaining ground as an important adjunct tool to evaluate disease activity.

Using a chalazion clamp to enhance dermoscopy of oral mucosal lesions

THERAPEUTIC CHALLENGE Dermoscopy has been popular in diagnosing skin lesion, but its use in oral mucosal lesions seems to be limited. Any lesion located in the oral cavity is difficult to operate on, as tissues there are moist, vascular, and pliant. A chalazion clamp is a useful tool for therapy and diagnosis of lesions located in the oral cavity. This instrument can also be helpful in assisting during mucoscopy. We describe the use of chalazion clamp to enhance dermoscopy of oral mucosal lesions. Our institutional review board approved the study.

Dermoscopy of melasma

© 2017 Indian Dermatology Online Journal | Published by Wolters Kluwer Medknow A 35‐year‐old lady presented with brown macules of centrofacial melasma within 6 months of child birth. [Figure 1]. She was euthyroid and had never used sunscreens, depigmenting creams (topical steroids/triple combination), or hormonal pills. Polarized videodermoscopy (EScope; Nakoda, ×20) of the cheek lesion revealed a pseudoreticular pigment network, diffuse light‐to‐dark brown background with sparing of the periappendageal region (follicular and sweat gland openings), brown granules, and globules, including arcuate and annular structures [Figure 2]. In few fields, increased vascularity and telangiectasias were well visualized [Figure 3].

Dermoscopy of alopecia areata in restrospective analysis

Background Dermoscopy devices can overcome the refractive properties of stratum corneum by interface medium or cross polarization such that the lesion can be easily seen. Aim To examine the dermoscopic feature in alopecia areata and correlate the severity of disease with dermoscopic features. Materials and methods Retrospective analysis of 72 patients suffering from alopecia areata (AA), irrespective of age and sex, who visited the dermatology outpatient department of a tertiary care center in Eastern India was carried out. The most recently developed cases of AA were examined dermoscopically. Variables included yellow dots (YDs), black dots (BDs), broken hair (BH), short vellus hair (SVH), and exclamation mark hair (EMH) on the basis of available literature and expertise. Results Yellow dots was the most common finding seen in 57 cases (79.16%), black dots in 51 cases (70.8%). Short vellus hair was seen in 32 cases (44.44%), broken hair was seen in 31 cases (43.05%), and exclamation mark hair in 23 cases (31.9%). YDs per field of vision was considered as the most common finding with increased severity of AA. Conclusion YDS, in increased number per field of vision, is the most consistent finding seen in severe cases of AA, as they are in progressive AA and alopecia universalis. An increased number of SVH and terminal hairs were seen in patients who were being treated.

Platelet rich plasma with microneedling and trichloroacetic acid peel for treatment of striae distensae

Material and methods: Ten patients with striae distensae affecting arms (n=6) and trunk (n=4) were included in the study. Under topical anaesthesia, PRP was injected over the entire area of striae by nappage technique using an insulin BD syringe (31 gauze) followed by microneedling with a dermaroller (1mm), the endpoint being pin-point bleeding. Microneedling was done over the striae and extended 2-4 mm beyond the margins. Trichloroacetic acid (TCA) peel (35%) was then applied with feathering at margins for 1 minute duration. Total three sessions were done three weeks apart. Clinical improvement were graded as excellent response (>75%), good (50-75%), partial response (25-50%) and poor response (<25%).

Dermoscopy of post kala-azar dermal leishmaniasis

© 2018 Indian Dermatology Online Journal | Published by Wolters Kluwer Medknow Post Kala‐azar dermal leishmaniasis (PKDL) is a late cutaneous manifestation of untreated or partially treated visceral leishmaniasis (VL) and is caused by the same organism, i.e., Leishmania donovani. It characteristically manifests as macules, nodules, plaques, and facial erythema. A 19‐year‐old male presented with erythematous fleshy papules confined to the chin [Figure 1], along with hypopigmented macules involving the trunk and lower limbs. On evaluation, the patient revealed a history of Kala‐azar 1.5 years back with RK‐39 test positivity for the patient. Dermoscopy of the erythematous papule from the chin was performed using Dermlite II hybrid m dermatoscope at 10 × magnification in polarized mode and photographs were captured, which revealed multiple yellow tears and erythema [Figure 2]. Histopathology confirmed the diagnosis of PKDL [Figure 3].
