“…This condition can be easily differentiated from talon noir by a potassium hydroxide scraping test which highlights its hyphae and spores [3,9]. Dermoscopy, a non-invasive procedure, can differentiate talon noir from melanoma preoperatively as the former shows homogenous reddish globular structures [10]. Acral melanoma, on the contrary, shows a typical parallel ridge pattern with irregular pigmentation.…”

Talon noir is an asymptomatic, self-limiting, dermatological condition that is most commonly seen in young athletes and mountain climbers. Histologically, the characteristic findings are intraepidermal hemorrhage and fluid collection due to shearing forces. Here, we report an interesting case in an elderly female, which mimicked acral melanoma clinically and alerted us to do a biopsy for confirmation.

Acral melanosis refers to increase in melanin pigmentation, in a diffuse, reticulate or focal pattern over the distal portions of the limbs and the head. The underlying causes are broadly classified as genetic or acquired, including various causes like hereditary, infections, inflammatory conditions, traumatic, neoplasms, drug induced and miscellaneous causes. We present seven cases of acral pigmentation with their clinical features, dermoscopy and histopathological findings. Here is an attempt to understand the subject better with the etiological classification and review of literature.
