An ectopic nail is an extremely infrequent disorder, also known as onychoheterotopia. Onychoheterotopia can present congenitally as well as in acquired form, although the acquired form is a rare occurrence. Ohya et al. first described the congenital ectopic nail in 1931. The growth of tissue resembling nails at sites different from the nail bed is characteristic of this condition. Acquired type or post-traumatic ectopic nail has been postulated to be due to acute or repeated trauma to the nail unit followed by transfer and inoculation of the nail matrix at another site. A posttraumatic ectopic nail is rare and unusual, making its diagnosis and management important. Histopathological correlation is necessary to confirm the diagnosis and differentiate it from other nail conditions. Here, a classic case of a post-traumatic ectopic nail in the left little finger in a male laborer following a cut injury is reported. The ectopic nail had horizontal growth and was approximately 5 × 3 mm in size and 1 cm away from the normal nail. After surgical resection and biopsy of the resected part, it was successfully diagnosed as a nail of ectopic origin. This is a rare case of a post-traumatic ectopic nail on the little finger with horizontal growth away from the normal nail.

Idiopathic guttate hypomelanosis (IGH) is characterized by discrete, multiple, round-to-oval hypopigmented macules of approximately 2-5 mm diameter, especially on the forearms and pretibial area,which increase in number with aging. Recent focus has been on therapeutic wounding, which stimulates melanocytes from the periphery and surrounding hair follicles to proliferate, migrate, and repigment the lesions. This study aimed to evaluate and compare the efficacy of trichloroacetic (TCA) 50% application and dermabrasion in IGH patients. Twenty patients of IGH were enrolled after considering various inclusion and exclusion criteria. IGH lesions over the right side were treated with trichloroacetic acid (TCA) 50% witha cotton-tipped applicator. IGH lesions over the left side were treated with dermabrasion. Of the 153 macules in 20 patients, all 81 macules in the dermabrasion group showed some repigmentation, whereas 7 (9.7%) out of 72 macules treated with 50% TCA Touch™ showedno improvement. At the end of 3 months, repigmentation up to 25%, between 25–50%, and between 51–75% was seen in 18.5%, 66.7%, and 14.8% of lesions treated with dermabrasion, respectively. This is while TCA 50% touch-treated macules showed up to 25% and between 25–50% repigmentation in 48.6% and 41.7% of instances, respectively. The analysis suggested that both dermabrasion and TCA 50% Touch are effective in the treatment of IGH. Dermabrasion proved to be more effective than TCA peel and can be tried before or with the medical line of therapy in the treatment of IGH.
