Abstract
Superficial acral fibromyxoma is a rare mesenchymal tumor that arises in the distal extremities and favors the periungual and subungual regions of the digits. Superficial acral fibromyxoma are benign, however excision may be warranted due to the presence of complications and potential for extension and damage of nearby structures. Here we present a rare case of ossified superficial acral fibromyxoma.
Highlights
A 19-year-old woman was referred to our clinic with a painful growth on the distal nailbed of her right third finger (Figure 1)
Physical examination showed a firm tender skin-colored keratotic papule located on the medial aspect of the distal subungual region of the third finger
An x-ray of the finger revealed a well-circumscribed 13 x 5 mm ossified mass in the subungual region of the distal fingertip without involvement of the underlying bone. She underwent surgical excision of the lesion with histopathology showing fibroblast-derived spindle and stellate-shaped cells suspended in a myxoid stroma without significant nuclear atypia or mitotic figures (Figure 2A) and ossification (Figure 2B)
Summary
A 19-year-old woman was referred to our clinic with a painful growth on the distal nailbed of her right third finger (Figure 1). The lesion had been present for a year without any trauma. Physical examination showed a firm tender skin-colored keratotic papule located on the medial aspect of the distal subungual region of the third finger.
