Acquired fibrokeratomas are benign and uncommon lesions consisting of collagenous papules and nodules covered by hyperkeratotic epidermis. These tumors occur mainly on the fingers and toes and infrequently on the palms and soles. They may possibly be triggered by a reaction to a trauma and presents as small and solitary dome-shaped lesions with a collarete of slightly raised skin at the base. Several case reports have been published of this rare lesion, with only a few investigators describing lesions of the feet.
