Dermabrasion is performed with help of dermabraders for removing the superficial (epidermal and dermoepidermal) skin lesions. However, due to their size, they are not suitable for dermabrasion of small skin lesions such as residual vitiligo patches before grafting, freckles, seborrheic keratosis, dermatosis papulosa nigra (DPN), milia, and warts. CO2 laser is a good option for these smaller lesions, but its availability is limited. Focal dermabrasion with bevel part of a hypodermic needle is a good option, but it requires dexterity to avoid prick injury.[1,2]
To solve the problem of dermabrasion of tiny skin lesion, we took a readily available cost-effective and aseptic disposable hypodermic needle (16/18G). The tip of the needle is cut or broken. The lateral edge of the bevel part is used for dermabrasion and blunt tip for focal dermabrasion and curettage [Figure 1a-d and Video 1]. Firm strokes are given on stretched skin from two directions at right angle. Thus, the customized needle can be useful for dermabrading as well as curettage of tiny skin lesions if needed. However, the blunt tip of the needle should be made curved for easier curettage. In place of customized needle, a broken or cut needle (21-23G) with its hub can be used for the same purposes [Video 2].
