Abstract
Acral fibrokeratoma is a rare benign fibrous tumor of an unknown etiology, typically found at the distal end of the toes. A detailed clinical examination is necessary in order to investigate signs of tuberous sclerosis. It presents the only clinically obvious anomaly. We report a patient with a typical presentation of fibrokeratoma.
Highlights
Fibrokeratoma is a benign solitay tumor that develops in adults on on acral areas such as toes and fingers
We report an interesting case of fibrokeratoma on a toe causing a longitudinal depression of the nail
Skin biopsy shows a finger-fibroepithelial lesion with collagenous stroma containing fibroblasts arranged in parallel to the axis of the lesion and ectatic vessels, which is in favor of an acquired acral fibrokeratoma (Figure 3)
Summary
Fibrokeratoma is a benign solitay tumor that develops in adults on on acral areas such as toes and fingers. Fibrokeratoma is usually asymptomatic, and is clinically presented as a flesh-colored papule or nodule dome-shaped, with a characteristic collarette [1,2]. We report an interesting case of fibrokeratoma on a toe causing a longitudinal depression of the nail. The examination revealed a swelling Subungual longitudinal median body that seems to have a relation with the matrix.
