A 53-year-old man consulted for this firm tumor on his 5th left finger. Clinical diagnoses were an acquired fibrokeratoma or a wart.
Dermoscopy revealed a peripheral homogeneous pigmentation and a
central white scarlike patch in favor of a dermatofibroma.
The lesion was excised and pathology confirmed this diagnosis of dermatofibroma.
Dermatofibromas are usually localized on the extremities , shoulders, thighs, buttocks.
Digital localization is rarely reported in the literature*.
Dermoscopy allows a more accurate diagnosis before excision of digital tumors.
